Devices for marking – labellers labellers can rightly be considered the most common marking device. Its use in large supermarkets, as well as in small retail outlets, such as markets or stalls. The main function of labellers – applying a price tag on the goods. That price is most often indicated by little more labels are attached to the package. In contrast to the self-adhesive price tags for manual fitting in the price labellers can easily label the large number of similar products. The second popular feature of labellers – drawing sheet. Reference is to the warehouse accounting definition of goods belonging to one group or another, and to simplify the sales process. Learn more at this site: Death by Robot.
The third function – application of additional information such as weight. Now it is very relevant label that says 'GMO' The basic amount of business costs in three of these functions for marking guns. But that's not all the good devices. Now becoming more popular with gun-etiquette cliches, which allow to put on the label, in addition to numeric and alphabetic values, and even small images (logos, or special. insignia).
Large companies often go to buy printer labels. When buying labellers should pay close attention to what kind of labels can be printed by this device. Depending on your needs, you can select single row, double row and three-line labellers. In addition, there are differences in what symbols are and what they may contain a number of each line. There are also different sizes of labels: 21h12 mm mm 26h12, 26h16 mm, etc. Below are some professional model labellers manufacturers produce etiquette feeds irregular shape and color, for example, a round sticker with a preprint firm Printex. The tasks are varied markings and attentive approach to choosing labellers can greatly facilitate your work.

Additional requirements. If you have any – any requirement for additional flow options, discuss them necessarily, and if possible execution – production. Example Objective: To measure the production line in volume flow additive with a density 800-900kg/m3, 10000-50000 cP viscosity, flow 5-50kg/chas, ambient temperature of 90-120 degrees. Celsius ambient temperature +5 – +20 degrees Celsius, the measurement accuracy better than 0,5%, the line pressure 6 bar, flanged, you need a remote electronic bypass adder with indication of evidence in the case with DIN and output an analog signal, as well as with alarm at the large and small stream. Based on this task, we need a set of flow meter with pulse output and electronic adder RT12, which has all the necessary functions (alarms, analog output). 1. Recalculate the flow volume of the mass, in terms of density.
2. Accuracy of measurements for such highly viscous liquids even without the use of linearization corresponds to the requirements of the customer. There is an inverse relationship – the more highly viscous liquid, we measure, the less the impact of factors that can impair the accuracy and hence better accuracy. 3. Highly viscous liquid – just refuse to use the turbine and blade models. After the conversion rate in accordance with the methodology for measuring highly viscous liquids, we see (through counting the volume density), which required meter with an operating range: for flow series and the OM MG – 41,5-520 l / h flow series with OM and MG special treatment of teeth Gear – 22,0-250 l / h flow MR Series – – 11,0-125 liters / hour.

The very name of 'synthetic materials' says that it will focus on materials produced artificially. As a raw material used oil, natural gas and coal. Through the transformation of these substances are obtained chemical compounds that determine their structure and specific properties of materials. CM can be divided into 3 groups: thermoplastics, elastomers and Duroplastic. This article focuses on thermoplastics, and one of the areas they application. Synthetic materials that are reused after heating up to become soft liquid state, and after cooling again acquire strength, are called thermoplastics. They contain linear or branched molecular chains, which are usually arranged randomly or have a certain structure.
The value of the physical forces between the molecules completely defines the properties and behavior of thermoplastics. In connection with the the fact that these properties depend on temperature, thermoplastic properties crucially depend on the temperature of application. Thermoplastics can be divided into two groups: – amorphous thermoplastics – their molecules are not ordered and have no internal structure (the structure of a lump of cotton wool) at 20 C, strong, hard and brittle – partially crystallized thermoplastic – they, along with the amorphous regions contain areas in which the molecules are arranged in an orderly fashion, they are at room temperature of solid and durable polypropylene is formed by the polymerization of propylene. Lateral methyl group CH3 can be spatially oriented in different ways (random or ordered) that produces propylene with different properties. If all the groups CH3 are on one side of the molecular chain isotactic polypropylene is called.

Ropes marking groups 1370 (140) – 1770 (180) are manufactured as standard, others as agreed. 5.Po mind covering the wire surface: no coverage; zinc-coated for: – osobozhestkih aggressive operating conditions (coolant) – Hard aggressive environments (R) – for medium corrosive environments (C). The surface density of zinc for the above groups (See chart on the above link) 6.Po purpose of war: gruzolyudskie (GL) – for lifting and transporting people and cargo, cargo (F) – for transporting cargo. 7. By Material core: – with an organic core (DC, from natural or synthetic material) – with a metallic core (MS.). Reference: Core provides internal support and cushion for the strands of the rope, and as a whole. It must withstand the radial pressure locks during loading of the rope, preventing its lateral deformation.
As organic cores are used cores from natural materials – hemp, synthetic and artificial materials – polypropylene. In the production of ropes are commonly used organic cores are impregnated with antiseptic and anti-corrosion compounds. Mass fraction of the impregnated composition is in the range of 25-50% by dry weight permanently core. To prevent corrosion, and organic core ropes are lubricated during manufacture of wire rope lubricants SC-50, KC-Y, Elaskon. 8.Po direction of lay of the rope elements: – Right Lay – Lay the left (A). ue. 9.Po combination direction of lay of the rope and its elements: – a cross-Lay – the direction of lay of strands in the rope opposite to the direction of lay of wires in the strands – Lay-sided (D) – the direction of lay of strands in the rope and the wires in the strands is the same.

In every industry there are problems that are associated with the connection of metal parts: obtaining reliable metal, the connection of large diameter pipes connecting the various body parts car and many more other tasks that can be solved only welding. There are various methods of welding, such as Thermoplastic, electron beam, gas welding and Electrogas. The most common type of welding is Electrogas Automatic and semi-automatic arc welding, which is used in the manufacture of complex and important structures, using a special welding wire, which moves in an arc, and arc moves along the line of welding. Welding wire, usually wound on a framed Ryadno coil and wire as needed continuously fed into the arc. Welding wire is used for cladding and welding low alloy and carbon steels in various fields, including shipbuilding. What is the advantage of using a wire? First of all, it is reliable and accurate joints capable of withstanding high pressure, highly-continuous welding process, low material consumption and arc stability. Welding wire is selected depending on what task you need to decide whether welding of pipes bodies, tanks, welding of shipbuilding steel, for certain tasks require a certain type of wire.
According to the chemical content of carbon and alloying elements were divided into three groups of welding wire: 1. Mild welding wire 2. Alloy welding wire 3. High-alloy welding wire less carbon content in the welding wire, the more plastic than metal. Depending on the type of wire, It may contain various alloying elements such as manganese, silicon, nickel, chromium, titanium and others.

Many believe that the ventilation is only needed for that would ventilate the unpleasant odor. In fact, the need is not just that. Dust as home and building a property accumulation, which in turn leads not only to the dirt and dust, but also to many diseases including in ourselves and respiratory diseases. Therefore, the design of ventilation systems is one of the most important moments, as closed on the building site, as well as in an ordinary dwelling. For many, the phrase ventilation design just is not perceived by the big words seriously, I bravely pointed out in vain. After having considered practically any situation can be easily noted that any building needs regular airing.
Closed construction site, this is certainly a significant amount of construction and street dust, which is also that fire not safe and can lead to diseases of the respiratory and nerve damage in your body. Design of ventilation is necessary to wisely, removing the wiring from flammable areas and distributing evenly drawing. Improper design of ventilation systems and can lead to opposite effects, such as regular drafts and correct ventilation, which instead of that would be aired and will draw on the contrary dust and dust accumulate in the corners. Home nook, your territory, but you can not even imagine the extent to which this fortress conquered enemies referred to as a lyutuyuschimi bacteria. Therefore, proper design of ventilation systems needed to support pure oxygen as the title of your ally. And if the house is home to a small child? Can you imagine what he is breathing, crawling on the floor? But the correct design of ventilation systems to help make the little beetles asthma.

This condition was not considered Podgorodnikov in the design of heating and cooking stoves FE-1 FE-2. In this regard, the rear wall of the oven is warming much worse than the front. As a consequence, these stoves are not widely available. Ray Bradbury has much to offer in this field. Stoves FE-1 FE-2 had improved my (patent of Russian Federation 2055272 from 27.02.1996g). You can do equivalent parallel caps (equidistant path of the gas), if necessary, a cap can be divided into horizontal diaphragm, and there should be provided with the best conditions for combustion, as well as separation of hot and cold gases, the separation of the diaphragm is necessary in the design of the Russian "teplushek", some designs of furnaces for baths, boilers, heating is not recommended caps with vertical crosscuts; flow of hot gases from the furnace (or a lower bell) gush with great speed, and extended as far as lifting, vertical crosscuts prevent the spread of natural gas, the lower cap in the volume, may have a variable cross-section and variable height (for example, part of the hood has a height of half of the furnace, and a part – full height, thus can not be installed at the top of the hood latch high summer course for Smoke opportunities through it) from the top of the furnace can do one or more outputs of hot gases into the hood (preferably away from the door), with filling bell on the ability to make uniform, the path of the gases in the cap to the connecting channel of equal better to do; gases from the furnace may be made to cover up or sideways, the back side of the chamber can not make the hole below the 12 range, to avoid clogging the furnace, the bottom of the firebox necessary to provide openings or dry seams to ignore the cold gas, hot gases are fed to the second cap from the bottom, it is important, and the filling cap on the ability to make uniform. .

For this reason the section of pipe in front of the dent and the dent remains in neprokontrolirovannym. Intratubal magnetic inspection Flaw PII Ltd. (U.S. Patent US 6,538,431) contains a number of bars mounted on the body flaw. In each bar of a pair of magnets and magnetic field sensors.
Magnets mounted on steel brushes. Each bar pivotally connected to the housing by means of three levers. Here, the first lever is connected to the front of the bar and the movable unit mounted on the body flaw and are able to move along the body axis of the flaw detector, the second lever is connected to the rear of the bar and the second mobile unit mounted on the body flaw and are able to move along the axis of the body flaw. The mobile nodes are connected with springs that provide a clamp sticks to the inside surface of the pipeline. The third lever is connected to the rear of the bar and the body flaw.
The advantage of this flaw is that the mobility of the bars relative to the body flaw in radial direction provides the cross-over restriction, regardless of the length of the pipeline sticks brushes. And the mobility of nodes along the axis of the body allows rounding dent the pipe. The main drawback of this flaw is that in the event that the motion inside the pipe flaw detector encounters an obstacle, for example, with the edge welded to the pipe-line frame, this leads to conflict front of the bar with an obstacle that affects the bar in the opposite direction of the flaw.
