A beltweigher or belt weigher, more commonly known as a belt scale, is a piece of industrial control equipment used to measure the mass and flow rate of bulk material traveling over a conveyor belt. [1] Invented by Herbert Merrick in the early 1900's, belt weighers are commonly used in plants and heavy industries, such as mining. [2]
A variable rate feeder (often shortened to belt feeder, or simply feeder) is a piece of industrial control equipment used to deliver solid material at a known rate into some process. Belt feeders vs. belt conveyors
An ammunition belt is a firearm device used to package and feed cartridges, typically for rapid-firing automatic weapons such as machine guns. Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes.
A vibratory feeder is an instrument that uses vibration to "feed" material to a process or machine.Vibratory feeders use both vibration and gravity to move material. Gravity is used to determine the direction, either down, or down and to a side, and then vibration is used to move the material.
The belt feed mechanism is a lever-type one, somewhat reminiscent of the vz. 52 and the PK, but with an unusual exposed lever hinged at the side of the receiver swaying horizontally instead of vertically. The top cover above the feed tray is very short to allow for quicker reloading and the mounting a receiver-integral optics rail. [2]
The ability to use G3 or STANAG (for HK23E) box or drum magazines is available with an optional feed module kit that consists of the bolt, recoil spring and belt feed module or magazine well. When employed in the belt-fed medium machine gun (fire support) role the HK21E provides a cook-off rate in excess of 1,000 rounds fired in quick ...
The M240 machine gun, officially the Machine Gun, 7.62 mm, M240, is the U.S. military designation for the FN MAG, [6] a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge.
The Model 4 of this weapon adopted the same belt-feed mechanism as the Type 99 Mark 1 Model 4. The Type 99 Mark 2 Model 5 resulted from attempts to increase the rate of fire. By modifications that included the addition of strong buffer springs, the rate of fire was raised to between 670 and 750 rpm.
