Sewing Machines

For the seamstresses, this is a huge pleasure when the sewing machines not only properly primed, but also work properly. Nothing is more interesting and fascinating than make their own decisions from various fabric! Yet improperly dressed sewing machine will not do anything but complexity as will fail and will certainly require repair. The thread is missing – about any sewing can not be considered. The thread is necessary for of the sewing machine to sew the fabric. For the correct operation of many sewing machines used two threads. There are certain features of filling top and bottom threads. In addition, each model requires a sewing machine certain threading. It is important to follow the advice, as this will save you time and ensure smooth operation of your machine.

It is helpful instructions and tips on threading, and we want to give readers of this article. Fill a sewing machine usually start with the upper thread. Before you start filling the upper thread is necessary and to raise the presser foot and set the needle thread take-up lever and the upper position. Then place a spool of thread on spool pin. The next step is to hold the thread from the spool through the upper thread guide to the upper thread tension regulator. It should be understood that the coils are different in form, but the principle works in all the same. Make sure that the thread is not too tight, otherwise it can end.

Then proceed to the bobbin. To do this, and take shpulederzhatel insert the bobbin with thread. It is necessary to ensure that the spool spins freely and not jammed. The main thing to know that properly dressed with thread – is the key to the success of the sewing machine. It's fun for you and your machine!

Covered Electrodes

Storage conditions (*): Electrodes should be kept in original packaging. The electrodes must be protected from rain and moisture. Storage relative humidity is 40% or less. Storage temperatures should be constant and greater than 15 C. Boxes with the electrodes should be stored on shelves or pallets to avoid direct contact with the floor and walls. During welding, the open air should be taken to prevent falling rain and moisture to open packs of electrodes. You should not take more electrodes than required for 1-day or 2-hdnevnogo consumption. Calcination: Rutile: Ignition is not required.

In the case of absorb moisture it is recommended electrodes calcined at a temperature of 100-150 C for 1-2 hours. At lower temperatures, calcination time, calcination should be increased. Cellulose Finish: electrodes with cellulose coating is not as susceptible to absorption of moisture. Calcination should be done carefully to avoid cracking. In general, however, ignite cellulosic electrodes is not recommended. In the case of appropriate calcination temperature should not exceed 70 C.

Main cover and alloy electrodes: If the electrodes are stored in the recommended conditions (15 C / RH 40%) and in original packaging the need for ignition is missing. When removing the protective film packs with basic electrodes past, ie electrodes should be placed in a heating chamber at 50 C. Calcining is recommended in case of autopsy cases and exposure of the electrodes exposed to air for more than 2 hours. Basic coated electrode alloyed electrodes and calcined for 2-3 hours at 250-400 C. It is not recommended, however, subjected to calcination the same electrodes for more than 3 times. It should be borne in mind that any packaging used, no matter how perfect it was, did not prevent the process of saturation coverage of the electrodes with moisture, but only slows down it. For example, tightly wrapped in polyethylene film electrodes with basic coating during storage in a humid atmosphere gaining an excessive amount of moisture and require baking already after 25-30 days when stored in dry area – after 120-180 days, in packaging and storing in sealed metal boxes – 1 year. Deadline for storing unpackaged electrodes in the workplace, depending on the humidity of air was from 2 to 8 hours. Thus, regardless of quality packaging and electrodes on a mandatory basis – especially when the responsible works – must pass before re-welding operation baking. (*) These terms and conditions of storage relate to the electrodes with basic coating. For electrodes with rutile and cellulosic storage conditions are not as stringent.

GRU Pressure

Gas control points or installation (EMG GRU) – special technological equipment and systems of gas distribution devices in the system of industrial and municipal housing supply. Serve to reduce inlet gas pressure after gas power station and its support for a given constant value, followed by submission to consumers. The main components of fracture: 1) gas pressure regulator, 2) filter for removal of solids, 3) pressure relief valves, 4) instrumentation, 5) meters of gas passing. Depending on the placement of equipment distinguish types of EMG: cabinet gas control points (GRPSH, RPn). The equipment is housed in a compact GRPSH metal cabinet and is intended to reduce the gas pressure with high or medium to the required parameters, and automatic support for the outlet pressure regardless of drops the input gas pressure and flow. In a system for cleaning GRPSH gas supply from various admixtures in accordance with the requirements of GOST, and to automatically adjust the gas supply in case of emergency increase or decrease pressure. GRPSH widely used as a stand-alone gas control points in the gas supply different sizes of settlements, industrial, agricultural, mlm municipal facilities.

With domestic gas supplies are used with a two-stage system GRPSH reduction. Gas control block points (GPB, SGS). The equipment is mounted in one or more containers (Blocks). Gas control plant (GRU, PG). The equipment is mounted on the frame and most often placed in the room, where the gas-powered plant (boiler, industrial furnace, etc.). The market offers a variety of SRC construction: houses, with two lines of reduction, with one line of reduction + bayzapas, with primary and backup lines, with two lines and two others bayzapasami and EMG may be a serial or parallel installation of controls, different configurations of gas metering, different placement of the entrance and exit, with one or two outlets, etc. When choosing a type of fracture are also important operating parameters gas pressure regulator (pressure at the inlet and outlet, the bandwidth), security and reliability in adverse environmental conditions (eg, at low and high temperatures), the protection system of various unusual situations. Today's manufacturers offer additional instrumentation for precision gas flow, as well as designs and manufactures gas control installation, based on the individual customer requirements.


For the production of breeze blocks and other building products, the following individual components: cement, aggregates, water, chemical additives – plasticizers and modifiers of concrete (at the request of customer). The binder material can be used by Portland both low and high grades, as well as medlennotverdeyuschy gypsum. As the filler used in any combination of sand, gravel screenings, concrete block, slag, ash, sawdust, peat, Styrofoam pellets, peschanogranitnaya mixture (CBC), marble chips, bricks and fight, etc. At a temperature of 20-25 C hardening products takes place in 20-25 hours. When used for shelving podblochnyh plates of steaming can be organized that will positively affect the strength characteristics and reduced curing time items, as well as reduce the production area occupied by up to 30-40 square meters. It is recommended to use Portland cement grade 400 (PC M400). When using cement mark 300 cement consumption should increase by 10%, the use of cement grade five hundredth reduces its consumption by 10-20%. For mini production breeze blocks, we recommend to purchase upgraded machine 'EP – 600'.

Its cost is 95 thousand rubles. It is intended for the manufacture of the method of volume vibropressing of heavy and light concretes wide range of products: 1.Plitka sidewalk and curb stone of various shapes and colors of the original. 2.Pustotelye and sandstone wall and partition stones, the elements overlap. 3.Dekorativnye walling and cladding stones of different colors. 4.Zabornye and lawn elements and other elements of the redevelopment. In the manufacture of concrete products used environmentally friendly materials: natural sand and crushed, lightfast pigments plasticizers, cement brand or M400 M500.

Bible World

Nothing has changed in the world, except my thoughts and Nate you: the rain has suddenly turned out contrary to the ordinary, says go for a walk grow up! And in the lumina of the clouds – the sun's rays. Soon the sun declare all of their rights! And write like! And want to live. And yet you want in a gym. Knead the muscles, feel your body. Problems? But who today without any problems! We shall solve in order of importance. Well now I'm saying "We will solve …" And just recently in my life was so besprosvet! Everyone probably it happens! Thought. Strangely, no one sees our thoughts, but they paint the world around us in certain colors. All the religions of the world assert that depression is a terrible sin, but we have neither the Bible nor the Koran is not read – and therefore do not know what sadness sin.

And yet it is so. Sadness is a sin not only before God but also to society, and in front of him! It has long been known that people communicating not only get their information from the words of the interlocutor, but also because of its filling, can of liver from the intestine may be, no matter where. After all, everyone knows, came across, was held. Standing talking to a man, he sings the praises and you you know: now asks to borrow money. And you do not like his compliments, even though you know that well-deserved compliments! Even more interesting to compare his feeling of a big city with good and bad mood. When the mood good, then the world is huge and beautiful.
