Title: Fuel cell cooling system - using surplus of reaction hydrogen for cooling the cells
Inventor: OHSAKI KOZO
IPC: H01M8/04
Filed: 1990-09-06
Abstract: A cooling system for a fuel cell is based on introducing a larger quantity of hydrogen in the fuel cell than is needed for an electrochemical reaction in the individual fuel cell units. The gas is introduced in the reaction gas phassage in such a way that it is partly used for an electrochemical reaction and the remaining part absorbs the heat of reaction as a cooling medium. A fuel cell (100) is supplied with hydrogen in excess from the pipe system (10, 20). The hydrogen surplus is passed by the pipe (230) for cooling to the exterior of the cell. An air preheater (1000) cools it by heat exchange with fresh reaction air introduced by a blower (400). ADVANTAGE - This requires no additional cooling plate and simplifies the control system.

Title: Power actuated chuck for lathe - has internal levers to enable centrifugal force of compensating weights to increase clamping force
Inventor: HIESTAND KARL
IPC: B23B31/14
Filed: 1991-03-27
Abstract: A power actuated chuck for a lathe has a piston (19) with inclined surfaces (24, 25) which engage matching surfaces on the actuating jaws (21) causing them to move radially. The actuating jaws (21) act on primary jaws (15) which in turn act on the gripping jaws (16) which can be moved radially inwards to grip a solid workpiece (10) or radially outwards to grip the bore of a tubular workpiece. When the chuck is rotating, the compensating weights (35) exert a centrifugal force on the levers (36) which exert a radially inward force on the jaws (15, 16) to increase the clamping force on the solid workpiece (10). When a tubular workpiece is held in the chuck the centrifugal force is ineffective. USE/ADVANTAGE - Lathe clutch which utilises centrifugal force to increase clamping force.

Title: Combined function control valve for constant displacement pump circuit - has pressure balancing spool for motor load control sliding inside low pressure relief spool for idle running
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B13/04
Filed: 1991-06-12
Abstract: A hydraulic valve (10) combines the three functions of pressure relief for idle running, circuit pressure limitation, and pressure regulation under load in a circuit for driving a motor (11) with a constant displacement pump (47). A differential pressure spool (22) with seating surface (29) and pressure surfaces (37) slides inside a second differential spool (19) with a seating surface (29) and pressure surface (38). The tail shaft (32) of the inner spool passes through a separating gland (33) into a chamber (23) housing a spring (24). The tail shaft end (39) is equal in area to the other pressure surface (37), so that the inner spool and spring form a pressure balance system. At the idle running or rest position (42) of the multi-way control valve (41), the outer spool (19) can lift off its seating at a low pump pressure, directing the total oil flow back to the sump (48). At a load position (51, 52) of the valve (41), the inner spool (22) is moved off its seating by pressure difference to allow proportional oil flow to the motor whilst the outer spool (19) is held against its seating. ADVANTAGE - Only two chambers and one spring are required. Easy to produce.

Title: Improved seal design for crystal removal lock of a reactor - consists of protecting the seal from direct radiation from crystal and avoidance of shear action in the closure
Inventor: DRECHSEL DIETER DR
IPC: H01L21/208
Filed: 1991-07-04
Abstract: Crystal growth, especially single crystal pulling form a melt, uses a melt containing chamber and a lock through which the crystal is pulled out of the melt chamber. The lock can be closed hermetically after the crystal has been pulled. The sealing action is simply by pressure between the lid and the lock with an absence of shearing action, and the seal ring (9) between these 2 parts, is protected (15) from radiation originating from the crystal being pulled. The closure part is pref. a lid which sits on top of a ring shaped seal (9) placed behind a heat shielding wall element (15), which is pref. an integral part of the cylindrical lock of the reactor. The element can be formed by turning or by welding to the cylindrical lock. USE/ADVANTAGE - The stressing of the seal is much reduced by the absence of shear stress. The protection from direct radiation reduces the thermal damage of the seal, allowing it to be used for more operations, which reduces the cost and improves the usable machine time.
