Loaded-piston gauges with self-centering pistons
Measurement Techniques, 1983This work on developing, commissioning, and operating a direct-loading machine for 1 tf (100 kN) gives rise to the following conclusions. The chain loading scheme with i0 links enables one to implement the lO-stage loading series recommended by the standards with monotonically increasing or decreasing loads.

An automatic-release piston for use in piston coring
Marine Geology, 1970Abstract An automatic-release piston has been developed to replace the conventional fixed piston/wire combination used in Kullenberg-type corers. At the end of penetration of the corer into the sediment this piston breaks into two parts. The actual piston is jammed in place by spring-actuated barbs that are pressed into the P.V.C. core liner.

Study on Piston Motion Control Strategy of Single Piston Hydraulic Free-piston Engine
2012 Second International Conference on Intelligent System Design and Engineering Application, 2012This paper investigates the piston motion control strategies of a single piston hydraulic free-piston diesel engine, which is intended to be a power supply for hydraulic propulsion systems. The Cycle fuel mass is determined by engine displacement and load.

Physical Review A, 1986
We report an experimental and theoretical study of the optical piston, a consequence of the phenomenon of light-induced drift (LID), observed in binary mixtures of Na vapor and a buffer gas. Good agreement has been found between experiment and existing theory as far as the shape of the Na density profile in the piston is concerned.

The piston remains one of the most challenging components to successfully design, and is certainly quite critical to the performance and durability of the engine. The root of the challenge lies in the piston’s role as the moving combustion chamber wall.

A piston compressor containing a housing (8) with a compression chamber (13) in it, having an inlet, and an outlet and a piston (10) arranged movably back and forth in an axial direction (X-X') in the compression chamber (13) between an upper dead point and a lower dead point, delimited by a kinematic mechanism (20) with which the piston (10) is ...

has to maintain a gas-tight chamber for the charge during its stroke, when hot or cold, and to transmit the combustion pressure through the connecting rod to the crankshaft. The excess heat in the combustion chamber is dissipated partly by the piston to the cylinder walls, so there must be sufficient surface contact, and the piston is expected to last ...
