Title: Hydraulic prop with filling and releasing valve and a return line of pressure liquid
Inventor: VOSS RICHARD
IPC: E21D15/45
Filed: 1993-04-27
Abstract: Provided for use in prop support systems underground is a prop valve (6) in whose housing (18) a non-return valve (26) for setting, a stop valve (34) for releasing and a pressure-relief valve (44) for protecting the prop against overload are integrated. The valve housing of the pressure-relief valve (44) is hydraulically displaced by the housing (18) also being equipped on the release side with a coupling piece (22) with gripping groove (23) and catch projection (24). A thrust pin (48) appropriately loaded by the pressure liquid acts on the valve housing and displaces the latter by a predetermined amount so that the stop valve (34) thus opens and the pressure liquid can flow off from the interior of the prop via the suction-pump connection (65) arranged on the setting side. Here, the passages or spaces are dimensioned in such a way that an increased quantity of pressure liquid can be discharged, this action being assisted by a pump attached to the suction-pump connection. …<IMAGE>…

Title: High active ethylene-selective metallocenes
Inventor: SCHMID MICHAEL
IPC: C07F17/00
Filed: 1995-06-02
Abstract: A cylinder assembly for a plate tumbler lock includes a removable, self-retained plate tumbler which snap-fits into an assembled position by pivoting the tumbler and pushing the tumbler into its ward until a projecting detent passes by a retaining ledge in the side wall of the ward. The force of the tumbler spring then pivots the tumbler into its assembled position where the detent is engaged with the retaining ledge. The pivoting of the tumbler is accomplished by locating the leg which forms the tumbler spring seat on the tumbler in a position where it does not interfere with the terminal edge which defines the open top of the ward during assembly.
