Sand rammer consists of calibrated sliding weight actuated by cam, a shallow cup to accommodate specimen tube below ram head, a specimen stripper to strip compacted specimen out of specimen tube, a specimen tube to prepare the standard specimen of 50 mm diameter by 50 mm height [1] or 2 inch diameter by 2 inch height for an AFS standard specimen.
A tablet press in operation An old rotary tablet press. A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A tablet press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals, nutraceuticals, cleaning products, industrial pellets and cosmetics.
The compression is done either by a single-punch machine (also called stamping press, achieves an output of approximately 200 tablets per minute, making it ideal for manufacturing small batches of tablets) or by a multi-station machine (rotary press). The tablet press is a high-speed mechanical device.
Manual goldsmith press General-purpose hydraulic shop press Power press with a fixed barrier guard A HACO CNC hydraulic press brake A press brake bending a sheet of steel. A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. [1]

Oil under constant pressure is supplied to the lifter via an oil channel, through a small hole in the lifter body. When the engine valve is closed (lifter in a neutral position), the lifter is free to fill with oil. As the camshaft lobe enters the lift phase of its travel, it compresses the lifter piston, and a valve shuts the oil inlet.

A rapid compression machine can be used for chemical kinetics studies. It is often used as an alternative to a shock tube for understanding specifically low-to-intermediate temperature autoignition chemistry under idealized automotive engine conditions.
