Sewing Machines

It should be noted that the sewing machines are capable of doing things. Such a pleasure to sew new masterpieces, giving them an amazing view through the sewing machine! Feature of the sewing machine is that it can all people, regardless of gender, age and position in society occupied. Many housewives alone sew clothes for themselves. The reason for that is too high a price fashion clothes, buy you can afford let not everyone. Here are just and there is a need to buy a sewing machine. It is using the sewing machine, you can create unique clothes, while significantly cheaper.

Many boutiques can be purchase patterns and sew them with beautiful items. Creative thinking, which possess many of the women can come up with their own design and sew clothes. In addition, much useful information can be learned from the fashion magazines! Sewing machines will always help to dispel the longing a gloomy rainy day. Working on the sewing machine, you will save money and in addition a lot to learn. To buy a sewing machine and start it properly used, not necessarily to be an experienced craftsman. In order to understand what is the essence of sewing, you can try to start sewing clothes for dolls. Thus, you will gradually pass to a garment for themselves and their loved ones. Once you learn how to handle a sewing machine, you can teach it, and their friends. The work on the sewing machine they will certainly be interested, since this is an interesting and necessary work. Well, not is no time to waste. Purchase a sewing machine today and see what she could.

Piston Compressors

Reciprocating compressor can be of two main types: beskreytskopfny and cross-head. Reciprocating compressor beskreytskopfny low productivity is simple construction, has the best weight and size characteristics, so that in addition to use in stationary conditions, widely used in portable and transportation applications where the requirements of compactness and low mass are particularly important. This kind of reciprocating compressor runs with trunk piston, and the differential pistons. The surface area of the piston facing the crankcase, is dead in the trunk piston plunger, and when the differential – it may be used only partially. The role of the crosshead to the piston beskreytskopfnom komprssore itself to do the piston through it on the wall of the cylinder piston is passed, the normal component of force. This leads to increased wear of the piston and cylinder and an increase in leakage of gas through the piston seal, which comes into the crater. When compressing, toxic and explosive gases must take special measures to prevent the ingress of gas into the engine room.

In beskreytskopfnom reciprocating compressor to lubricate the cylinders and motion mechanism used compressor oil with sufficient viscosity at high temperature of the walls of the working chamber, but too viscous for motion mechanism, which leads to additional costs of the mechanical friction. Beskreytspkofny piston compressor inferior kreytspkofnomu to friction losses, in addition, at the same productivity they have big bore. The main advantages beskreyptskofnogo piston compressor – low weight and dimensions. Reciprocating compressor for the location of the cylinder axes in the space is divided into vertical, horizontal and angular. The most widely used angular reciprocating compressor with cylinder axes, symmetrical vertical (Y-and W-shaped), and vertical-horizontal (U-shaped or square).

Vertical reciprocating compressor has a smaller area, but a great performance is much more difficult to maintain. Cylinders vertical crosshead compressors are smaller and uniform wear, vertically directed forces of inertia are absorbed better foundation from which it can facilitate. The temperature and the elastic deformation in the vertical compressors are free. Horizontal reciprocating compressor – large cross-head compressor medium and high productivity. Widespread in recent years received a horizontal reciprocating compressor cylinder arrangement on both sides of the shaft, the so-called Boxer compressor, which has a substantial advantage over other types of compressors. The main advantage of boxer piston compressor in multilayer performance to the location of each row of one cylinder. In stages of low pressure where the volume of compressed gas is large, it is possible to have two or more cylinders in several rows. Therefore, the diameters of cylinders and pistons were significantly lower than in the horizontal reciprocating compressors previous designs with an arrangement of cylinders on one side of the shaft and the differential pistons. This made it possible to reduce the mass of moving parts and thus the value of the inertial forces. Angular reciprocating compressor V-, W-, fan-and star-shaped with odnokolennym shaft, joined by up to four rods. In the angular reciprocating compressors, especially when fan-shaped and star-performance, can be used also trailed rods, attached to the bottom of the head of the main rod. Angular reciprocating compressor with low productivity holds beskreytspkofnym, average – with kreytspkofom. The main advantages of angular piston compressor: well balanced with counterweights; cylinders are far removed from one another in the space between the rows of vertical and horizontal machines may be located in between refrigerator design simplicity and short length of the shaft, which promotes the use of rolling bearings, easy installation.

Venetian Plaster

Venetian plaster – a liquid marble. The very name "Venetian Plaster" is a literal translation of the Italian expression 'stucco veneziano'. Composition and application technique was invented in ancient Rome. When processing of marble were . Apparently, then at some of the architect, whose name history has not preserved, and the idea to use this material for creating artificial marble or onyx. So there was this clear plaster on the basis of many components, chief among them – lime and marble flour Classic Venetian plaster is known since the Renaissance, which created the unique color of Venetian palaces. Durability, the amazing beauty of facades and interiors of buildings, centuries standing in the water, partly through this unique material, which was called 'Venetian plaster. " Venetian plaster can transform a home into a palace.

In the modern interior design in recent years more and more popular imitation of natural materials. That is the type and applies the Venetian plaster, which allows to issue walls and decor elements under natural marble. Drawing can be applied in different ways, that allows you to create clearance for the most refined taste and to fully realize the vision designer. Today, Venetian plaster can return to the beauty of noble walls of ancient times. Of course, time has made adjustments to her recipe. Today in the plaster comprises marble and granite dust, slaked lime, organic and inorganic pigments, water and latex emulsion.

But one thing remains unchanged: a classic technique of applying an effect veneer with natural stone. Coverage always consists of multiple translucent layers. Their number varies from 2 to 10 – the bigger, more noticeable glow plaster. The wall appears translucent, and the pattern is read in depth, though we face the real veins of natural stone. Venetian plaster is applied a layer thickness of 2-3 mm. Applied with a spatula, a metal trowel on cement and cement-lime plaster, concrete, brick, asbestos and gypsum plasterboard, particleboard, fiberboard, and other similar surface, as well as old coatings based on aqueous dispersion, alkyd and oil paints and whitewash, after pretreatment of the surface. Sometimes a wall is covered with wax – it strengthens the gloss coating and gives sense of optical illusion. Thin film changes the angle of refraction of the light beam, and it seems that the wall is not flat, but as it goes deep. This is an amazing property Venetian plaster that distinguishes it among Other building materials. Decorative effect is achieved in different ways: the pigment is added to the composition itself, or applied on top. In addition, the plaster after the application has portions with different porosity, which gives the game light depending on the lighting. Venetian plaster environmentally safe, non-toxic, can apply for child and medical institutions, does not contain organic solvents Classic Venetian plaster – expensive elite coating, a large fraction of the cost of which – is work. But thanks to the longevity of "Venetian" eventually turns out to be significantly cheaper than, say, finish wallpaper that will have to glue every 3-4 year. Proper treatment will last as long as the wall will stand. Venetian plaster has always been used to design the most beautiful and affluent areas. White stucco can be found in European cathedrals. Raphael and other artists of that time hiding film used Venetian plaster to decorate the palaces and park pavilions. Then she served for framing artworks from the era renaissance today combined with any style and decor.
