Title: Multipurpose triaxial testing cell for geological materials
Inventor: SECQ J
IPC: E21B49/00
Filed: 1990-06-12
Abstract: The invention relates to a multipurpose triaxial testing cell for geological materials such as rock or clay. It is characterised in that the main piston (6) has a collar (28) which fits into a bore (29) provided in the upper wall (16) of the body (8) in order to delimit therein two annular chambers (30, 31) of complementary volumes, and in one (30) of which chambers, namely the chamber called the lower chamber which, with respect to the collar, lies on the same side as the sample, a channel (32) emerges, through which a fluid can be introduced in order to exert, on that of the radial surfaces (33, 34) of the collar which is turned towards the chamber (30) in question, a force which, directed along the longitudinal axis of the piston, tends to move the piston towards the outside of the test chamber and therefore to unload the sample.

Title: Liquid esp. water handling equipment e.g. for condensation in domestic refrigerator or cold room - using lower collector connected to liquid source by non-return valve and also to source of pressure
Inventor: GERALD ANQUETIL
IPC: F25D21/14
Filed: 1992-08-21
