Belt Conveyor:

This type is available in two common forms: flat belts for pallets, parts or even certain types of bulk materials and troughed belts for bulk materials. Materials are placed on belt surface and travel along the moving pathway. The belt is made into a continuous loop so that half of its length can be used for delivering materials and the other half is the return run (usually empty).

The belt is supported by a frame that has rollers or other supports spaced every few feet. At the each end of the conveyor ( where the belt loops back) are driver rolls (pulleys) that power the belt.

Scleroscope:

The Scleroscope test has the distinction of being the first commercially available metallurgical hardness tester produced in the United States. The instrument continues to be used extensively in selected applications.

The test consists of dropping a diamond hammer, which falls inside a galss tube under the force of its own weight from a fixed height, onto the test specimen and reading the rebound travel on a graduated scale. The height of the fall is 250 mm. The hammer is a little less than 6 mm in diameter, 19 mm long, and weights about 2 g. Te shape of the diamond is slightly spherica and blunt with a diameter of approximately 0.5 mm.

Discontinuous Chip(in Metal Machining):

When relatively brittle materials (e.g. cast irons) are machined at low cutting speeds, the chips often form into separate segments ( sometimes the segments are loosely attached). This tends to impart an irregular texture to the machined surface. High tool-chip friction and large feed and depth of cut promote the formation of this chip type.

Serrated Chips(in Metal Machining):

Serrated chips are semi-continuous in the sense that they possess a saw-tooth appearance that is produced by a cyclical chip formation of alternating high shear strain followed by low shear strain. This fourth type of chip is most closely associated with certain difficult to machine metals such as titanium alloys, nickel base superalloys, and austenitic stainless steels when they are machined at higher cutting speeds. However, the phenomenon is also found with more common work metals (e.g steels) when they are cut at high speed.
