Along with hoses comes a requirement for hose connectors. There are a myriad of different types and sizes of hose connections that are perfectly suitable for compressed air. However, there are only few basic connectors that are typically used. above Figure shows two different male NPT × hose barb fittings. The combination nipple is a

Most compressed air systems require at least one regulator, and in many situations they require a large number of these devices. A pressure regulator is a control device that takes a high input pressure and lowers it to a usable output pressure. The most important regulator in the system is the master regulator, which is

Centrifugal fan are commonly found in commercial heating, airconditioning, and ventilation systems. In this role they serve the same function as a squirrel cage fan as a prime air mover. A centrifugal fan can produce a higher output pressure than a squirrel cage blower and, therefore, is the preferred choice for pumping large positive pressure

Rammers are shown in above Fig. . These are required for striking the molding sand mass in the molding box to pack or compact it uniformly all around the pattern. The common forms of rammers used in ramming are hand rammer, peen rammer, floor rammer and pneumatic rammer which are briefly described as (i) Hand

All wooden objects whether doors, windows, furniture, pattern, core boxes, handicrafts, toys, cots, etc., are all assembled with joints. The various common used wood working joints are given below

Chisel is a strong sharp edge cutting tool with a sharp bevel edge at one end. Its construction is composed of handle, tang, ferrule, shoulder, and blade. Chisels are generally made up of high carbon steel. They are used to shape and fit parts as required in joint making. A gouge is a curved chisel.

Various kinds of cutting tools namely various kinds of saws, planes, chisels, scraper, files, and rasp adze and axe and boring tools such as brace and bits, bradawl, auger, gimlet are used in the carpentry shop. Few important types of cutting tools are described as under. Saws Saws are wood cutting tools having handle and

Defects in timber may be broadly classified into three major categories : Defects Due to Abnormal Growth of Trees Defects due to abnormal growth of trees are natural in nature and they are knots, stakes, twisted fiber and rind galls. Knots are too much frequent in many trees. They break the continuity of fiber and

Hard wood is generally obtained from broad leaves or deciduous trees where as the softwood from trees having needle shaped yes or conifers. The major differences between hard wood and soft wood are given as under The most important distinction between softwoods and hardwoods is that almost all hardwoods contain a type of cell called
