PURPOSE:To cut off a running clutch at the same time as braking force for a brake starts up by working an inching valve in detection of boost chamber pressure of a brake assistor. CONSTITUTION:When a brake pedal 6 is trod, an operating rod i, a spool valve e of a booster 22 for a brake assistor moves through an input rod k to the left, a return valve part o is closed at the same time as oil pressu...

Lumps of a mineral or like material comprising two or more solid phases at least one of which is electrically semi-conductive and of different conductivity and permittivity from the other or others are subjected while immersed in water or other high dielectric medium, to the action of an electrical discharge of high enough potential to ionize the mineral. The discharge so generated crushes the lum...

A data processing system consists of a number of modules such as integrated circuit chips, each of which receives a clock signal. Each module contains a checking circuit 22 producing a failure signal which indicates whether or not the module is operating correctly. The clock signal is used to invert the sense of this failure signal in successive clock periods. Thus, the failure signal normally alt...

A non-collapsible medical fluid container is disclosed, with microporous filter means mounted on the interior end of a vent conduit that extends into the container for venting displacement air thereinto. The filter means, preferably a rigid microporous depth-type filter frictionally mounted on the end of the vent conduit, is mounted closely adjacent to an interior surface of the container to preve...
