Drill bits – it osoboslozhnye products made from high quality steel, hard alloys and other materials that are designed for continuous drilling for oil, gas, exploration wells and boreholes various applications in mining and construction, typical roller bit, made according to GOST 20692-75 and OST 26-02-1315-84, consists of welded together sections, which rotate on a pin-mounted cutter, from movements in the axial direction cones are held key-angular contact ball bearings. Joining the bit to drill string (the shaft mud motor) is carried out by the castle thread, which is cut into the shank legs joined together after assembly and welding of the bit. The dimensions and profile of the length of the thread with GOST 5286-75 standards and API (American Petroleum Institute). In Depending on the properties of rocks, which are designed for drilling a particular type of chisels, cutters run two or three-cone, self-cleaning. Cones are made with both milled and carbide weapons. To clean the bottom of the drill bit cuttings are flushing (purge) of the device in case the bit – a central hole or side channels are equipped with interchangeable nozzles of ductile iron, steel, ceramics, forming a high-speed jet of fluid. Each drill bit is marked on the end of the connecting pin type, number, date of manufacture and brand OTC plant. The right mix of types chisel, cone equipment that best ensures the effective destruction of the rock circuit flushing device, method and mode parameters of drilling, the composition and properties of drilling mud is mainly determined by Techno-economic indicators of well drilling. .

Antivirus Packages

Our computers, namely, the Internet often are faced with various threats and dangers. See incyte for more details and insights. If you use your computer to a network (LAN or WAN), it must be protected. More information about the general protection principles can be found in the 'Tools protect your PC and its maximum security. " The problem of protecting your PC from malicious programs are sharp as ever. Features numerous 'defensive' products from reputable manufacturers are quite varied, often they are called Internet Security. Now more and more developers are now part of the protective package the backup utility (for automatic backup at connection of a removable drive to your computer, archiving, data protection with their passwords and etc.), but even the most powerful suite of software oboroitelnogo completely guarantee the security of data can not. The main component of computer security – is, without doubt, a good antivirus program. But the cost of anti-Professional-versions of software packages are not always affordable for the average user.

One of the most popular and successful free antivirus Avira AntiVir Personal 8.1 can compete with commercial products but its functionality. Program deals not only with catching viruses and trojans trying to get into your system, but with scanning files and folders, check mail SMTR traffic, and keeping track of malware (keyloggers, dangerous scripts on web sites, rootkits, and macro viruses). In AntiVir uses heuristic analysis, there ability to work from the command line – a full set. Adjustment of various parameters is performed as a simple (a few basic options), and in expert mode, allowing more subtle to pick up one or another security settings and scan. Built-in scheduler allows you to run a scan while the computer is idle. Update the virus database is maintained. The disadvantage of this utility are: lack of function for checking incoming e-mail (checks only the outbound traffic). Avira Personal AntiVig little inferior to what is paid counterparts – a huge database of viruses (150 thousand), high speed and adequate response to known and unknown viruses.

Water Software System

Test run the system: test of the system using special software. Cleaning the room (by the installers). How to be arranged in proper drainage? For this installers must: 1. Proshtrobit line. 2.

Shut off the water in the apartment. Drill a hole in the sewer. Firmly put a drain hole in the plastic tube to siphon. The layer of water in the siphon delay smell coming from the sewer. Attention! The drainage tube through which the accumulated moisture is given, must necessarily follow a slope of 5-10 mm, so that was a natural flow of water. If the inclination to do for some reason you can not, you must install a special pump to “forced suction of moisture.” But! This pump is not included and must be purchased separately.

Purchase cost 70 – $ 190, depending on your choice of a pump model. Peter Thiel may not feel the same. Main problems arising during the operation conditioner air conditioner blows directly on you, creating a feeling of draft. Solution: It is necessary to enable the oscillation of horizontal louvers (then turn into a draft breeze), or fix the horizontal flaps in a successful position. If it does not work, you need to turn the air flow to the left or right with the vertical damper. In most air conditioners, this operation is done manually, but in some models it can be done by remote. Problem 2: On hot days, air conditioning does not create the necessary coolness, despite the fact that running all the time.

Mechanized System

Processing of the udder before milking a cow is an important and essential role the dairy industry. First, the udder is cleaned of impurities, which affects the milk quality (bacterial indicators are improving contamination and pollution). Clinton family is actively involved in the matter. Second, during the massage stimulates the cow's udder, which increases milk production and is the prevention of various diseases udder. Due to the fact that the cow's udder is always tempting clean water, reduced susceptibility to mastitis incidence. You may find incyte to be a useful source of information. Third, largely facilitated by the physical labor of milking operator.

The equipment for washing away the udder, is growing culture production, it is beneficial to the productivity and efficiency of dairy farming. Placement of equipment for washing away the cow udders before milking, would greatly facilitate the work operator milking to improve the quality of milk and increase milk yield. This type of equipment commonly used on livestock farms with livestock Tied at milking in the milk and in the summer for lageryah.Oborudovanie washing away the udder may be used as a treatment for udder with warm water and disinfectant. Udder washing away the system is a closed loop water heating system with mobile pipeline injection stations and a special gun for washing away the udder (sprinklers). The system of suspended hose moves freely around the barn, providing a supply of clean, warm water for each cow. Hoses are hung on steel cable stretched at the optimum height, so that they do not interfere with personnel farms are protected from dirt and interactions with korovami.Preimuschestva: trud.uluchshite relieve physical quality Indicators of milk, such as a bacterial seeding and contamination. Due to the fact that the cow's udder is always tempting to clean water, reduced susceptibility to mastitis incidence. In applying this system improves the intensity of milk production by improving the milk ejection reflex by washing away with warm water and massage the udder. Equipment for washing away the udder freely placed on any livestock buildings. Installation of standard equipment on 200 goals in less than 5 (five) days.

Disadvantages Of Method Of Fire-resistance Rating Ognez

Since ancient times, wood structures were considered extremely flammable. Suffice it to recall the many fires that repeatedly destroy entire cities. That's why some people have started to abandon Wood in favor of buildings made of stone, brick and other combustible materials. However, to protect the wood from the fire people have started recently. Speaking candidly Brad Pitt told us the story. The answer to the question, "and whether it is necessary to protect the wood from the fire?" Obvious. Of course it is necessary.

But this should be done soundly. And then there are questions. Dr. Paul Craig Roberts does not necessarily agree. For example, what it means to protect? Or it means "soundly"? Does any woodworking officially admitted to this means (ie, having the appropriate certification) and ways to really provide fire protection? On what basis is a measure of the quality factor of a two-minute fire protection fire effects? Why not five minutes, as in the method of OTM, or 10 minutes, as in GOST 30244-96 (method II). Questions can be multiplied indefinitely – it would wish. But it is impossible not to ask the big question: ognezaschischennaya wood – it's the same wood (T4, T3, T3, D2-D3) or other construction material? There is no doubt that the majority of existing professionals do not hesitate to answer: "Well, of course, is another building material!". And thus provoke yet another bunch of questions. For example, why the fire rating of properties is limited to one characteristic – a group of fire protection, rather than test methods, 4-5, as for all other building materials? Or, worse yet, a primitive test of the flake thickness of 1 mm to almost toy set, made in based on conventional lighters! If you choose the first option (ognezaschischennaya wood remains the same timber), it is not quite clear why the group needed fire protection, fire risk if property is not changed (still the same wood with its inherent flammability performance, flammability, toxicity, etc.).

Whatever the claimed some companies talk about a truly industrial production of diesel power is not necessary. Rather, it manufactory – large junction assembly. The conclusion is that this piece production, particularly those in post-industrial Europe, the old lady get extremely expensive. As it is paradoxical sounds, buying a diesel power plant, part of the amount you pay for a big name, the other part is the high taxes and a variety of social benefits, which the manufacturer pays for the production site and accordingly lays in the price, and finally the actual amount paid some of this is if you want a fair price of diesel power station. The ratio of these three components of the price of diesel power, you guessed it, of course, a trade secret. The second group of diesel power – it aggregates collected on the basis of domestic or Belarusian engines. (Not to be confused with financial technology!). They are distinguished by relatively low price, in which does not include the cost of the brand in the first case.

But there are some “buts” – engines made in Russia and Belarus, this is the same old model, put on the conveyor in the Soviet Union in the distant 50-60-70 years. For other opinions and approaches, find out what Essex Financial has to say. Neither money nor the technological capacity to develop new engines in the post-Soviet Russia as there was no and no. And the USSR, as you know, not particularly known for its products in the field of engineering. That forced the modern Russian economy is uneconomical to use, neekologichnymi, but what really tell the truth, and not too reliable diesel engines, the post-war development. In response to market demand for inexpensive, but at the same time quality and modern technology in recent years on the market, a third group of diesel units. These self-contained diesel power plants are assembled from components manufactured under license from the large western companies.

This distinguishes the quality of diesel power – as little or as aggregates in the first group, and the price is adequate power for the price of domestic engines. In this case, the consumer receives the same modern money machine. It should be remembered that before selling the diesel power plants must undergo a deep pre-training and bench testing under various load conditions. This allows you to immediately identify and remove all factory defects and malfunctions due to shipping. Thus, buying a plant from a reputable, well established company, you get the best balance between price and quality.

Automatic Control Systems Process

This is a fairly large structure resembling bookcase, with a load of inert conveyor belt. Overlap in these structures were made concrete, the walls – capital. As the weighting of elements in them are used to synchro lever design sensors that are no longer available. Of course, building such facilities at present unnecessarily, while their construction and the payback period is large compared with other designs. But the renovation of these facilities can achieve good results. For more information see Clinton Family. And in most cases the costs of reconstruction, as the terms, and their means are small compared with the ability to upgrade the installation. Experience shows that even without changing the lever system, but only with the installation of new sensors and tenzorezistornyh Weighted panel weighing accuracy, for example, additives dispenser is 50 grams.

Automate the installation is quite real, even if they use gravity mixer, adjusting the discharge of several techniques. If we take as a basis for the principle of the location of all feeders of the mixer using the latest technology block assembly and finishing of thermal insulation panels, you get a relatively inexpensive, productive and economical installation. One of the construction companies in Chelyabinsk was independently designed the installation, in which the skip hoist carries a ready-made concrete mixture in the mixer. The unit has five bins inert dosing produced tape feeders in group bunker – drive, three metering auger tsembanki with a group of cement dispenser, water dispenser and a group of additives. Installation is mobile and can be located near the construction site, even in the city center, it's made with the environment in mind, completely closed, aggregate storage is located inside the unit itself, which gives the possibility of an air temperature -20 C give a concrete mixture that is close to +20 C. Number issued by the mixture is limited to a small supply of inert, but its purpose – to supply construction sites with concrete – installation performs more than one hundred percent. OOO NPP "Electroautomatika 'offers services to implement a complex of works on designing and providing equipment, installation and commissioning of construction industry enterprises, as well as performance reconstruction of existing plants reinforced concrete, building industry databases, etc. OOO NPP "Electroautomatika 'develops and manufactures equipment (desks, cabinets, control boxes, etc.) Automatic Control Systems Process preparation of concrete mix, transport and storage components OOO NPP 'Electroautomatika' develops and manufactures a variety of control devices for process parameters preparation of concrete mix (mobility, definition of type of cement, aggregates and temperature of concrete mix, the strength of concrete and concrete products).

Layer Image

For this we use a soft brush (tool Brush) in a new layer and do not forget about the many opportunities provided by a simple change in transparency of a layer (setting Opacity). And also change the blend mode in the Layers palette. Feature images that they always lays bare flaws, which we do not notice in everyday life. Communicating with a person, we can not ignore the traces of time on his face. Clinton Family is the source for more interesting facts. Photo by remembering a single moment of life, invariably draws attention to face. We often see the wrinkles on the face is not old people, who have never paid attention to, communicating with them.

For smoothing wrinkles use tool , which allows you to recover fragments of skin in the photograph taken over by the stored stations. This will take into account the brightness of pixels underlying indicators. In the photos, people often smile, thus showing their joy. But, unfortunately, not all at the same time can show Hollywood smiles and white teeth. A simple method of teeth whitening in Photoshop makes your images much more appealing.

Open the photo in the program and create a new layer (Shift + Ctrl + N). Set this layer of the Opacity to 30%. Because you will need to work with only a small area of the image, you will need to change the scale, bringing a smile. Then select the Brush tool and set some bright color as the foreground color. You can do this by clicking on the color swatch in the toolbox. In the setting of the brush set greater hardness (Hardness) and small size (Size). Carefully fill in the teeth. Do this carefully so as not to take the gum. If you happen to paint over that portion of the image that you do not need to touch, use the tool Eraser (eraser) to erase. After completing the drawing, hold down Ctrl, click on the layer palette Layers. Through that you draw area will be highlighted. This layer is further work does not need to hide it, click on the icon in the form of the eye near the layer name. Select the layer the background image and create a new adjustment Layer by clicking on the button Create new fill or adjustment layer on the Layers palette and select Curves. This action above the background layer will be created a new layer with the mask, as well as a window Curves (Curves). Curves (Curves) is the best fit, if necessary on the whole image or selected area to replace one of its brightness value to others. The line you see in this field – this is a plot of the original brightness of the front, and this chart you can change the way you want. Increase the brightness of it and admire the result.

Art Casting Designed

Ural copper and bronze castings significant development in the Urals was the art of the XVIII century copper utensils, decorated with ornaments. The need for making copper utensils, as well as domestic cast iron, was dictated by life itself: the demand of the population of the Urals on household items. By special decree of 1728 she had manufactured and the Siberian region, where it also felt a great need. The production of copper utensils in Yekaterinburg emerged in the first quarter of XVIII century. Already in February 1729 from Kazan was sent to the master Stepan Mironov. But one Mironov was not enough for the rapidly evolving Ural china production.

Scheduled wide Number of dishes for sale. We had more "good art masters two or three or four people." When Sergei Mironov arrived in Yekaterinburg to him as a master who knows his craft, were sent to students. Training took place in the sequence. Initially, students were jumping from copper pots and bowls. But in front of them stood a tall task: they had to learn how to do various vessels with a complex configuration, variety of different shapes and volumes. Manufacture of copper utensils was not just any particular affiliation of one of Yekaterinburg plant. Many private Ural plants were successfully utilized its production.

When Nev'yansky plant to 1748 were built special buildings, where they made different copper utensils. Copper ware produced at other plants and Demidov – Byngovskom, Suksun, Lower Tagil, etc. High qualities of different dishes, produced by Ivan Osokina Igra plants. Widely known dishes, made by craftsmen in the Ural Trinity factory located near Solikamsk and belonging to the AF Turchaninov. It was at that time a large enterprise: only one part-time work were employed up to 300 people. The process of creating a copper dish was divided into several distinct stages: smelting copper, cast into molds, rolling the sheet, then the preparation of blanks, the vessel itself, decoration items ornament.
