Abstract: An immersion pump assembly comprises a pump and a wet-rotor motor driving the pump. The motor and the pump have a common shaft which is closable and hollow and which is partly filled with a fluid, for dispersal of waste heat from the rotor chamber of the motor into a heat sink provided by the liquid to be conveyed by means of the pump. The shaft together with the fluid constitutes a rotating heat pipe system.

Abstract: This invention relates to an air trap for shutting off flexible plastic tubing, particularly infusion tubing, for instance, during a transfusion of blood the air trap will reliably shut off the supply of blood when air bubbles are contained in the liquid entering the infusion tubing. This is ensured in that the air trap for shutting off flexible plastic tubing, particularly infusion tubing, comprises a flat head (mushroom-shaped head), which on one side bears on a ciaphragm, which defines a pressure chamber, and on the other side is provided with a guide stem, which is provided with means for squeezing a flexible plastic tubing in a receptacle and is operable to release the tubing in the receptacle under the action of a gas pressure in the pressure chamber and is spring-biased to cause said squeezing means to squeeze the flexible tubing in the receptacle when the pressure chamber is pressure-relieved.

Abstract: A fuel pumping apparatus of the rotary distributor type includes an accumulator volume into which fuel can be spilled to terminate delivery of fuel by the apparatus. The accumulator is defined by a movable member in the form of a sleeve which is slidable on an extension of the distributor member and has a closed end. The extension defines a seating with which can be engaged by a valve element defined by the sleeve. The extension and sleeve define an annular space connected to the pumping chamber of the apparatus and mechanical means is provided to effect initial movement of the sleeve against the action of a spring to lift the valve element from the seating to allow fuel flow into the accumulator volume.

Abstract: A fuel injection nozzle comprises a valve member which is biased into contact with a seating by a spring supported on a spring abutment having an integral extension which projects through an aperture in the end face of a holder which carries a nozzle body in which the valve member is located. The valve member is in engagement with the extension. A sleeve surrounds the valve member and is slidable in the body and is engageable with the extension. The valve member and the sleeve move together against the action of the spring under the action of fuel pressure to allow fuel flow to an outlet. The movement of the sleeve is arrested by a stop surface defined by the end face of the holder. The continued movement of the valve member being under the action of the fuel pressure acting on the valve member alone, until its movement is arrested by a stop.

Abstract: A rotary distributor fuel injection pump includes a rotary distributor member movable axially in a body part. The distributor member has a transverse bore in which is mounted a pumping plunger. At its outer end the plunger is engaged by a cam follower including a roller which is axially movable with the distributor member and which engages cam lobes formed on the internal surface of a cam ring to effect inward movement to the plunger. Outward movement of the plunger is effected by supplying fuel to the bore and the extent of outward movement of the plunger is limited by stop rings on the opposite sides of the cam ring. The stop rings are mounted in the body and define internal inclined surfaces which are engaged by end portions of the roller so that as the distributor member is moved axially the extent of outward movement of the plunger will be varied to control the amount of fuel supplied by the pump.

Abstract: The apparatus serves for a slipless conveyance of two coextensive parallel plates, which are in register and transversely spaced apart and supported on those broadsides which are remote from each other in respective planes of travel. The apparatus comprises at least two vacuum-applying conveyors, which are adapted to be driven in synchronism in a direction of travel and extend parallel to each other and are disposed opposite to each other and transversely spaced apart and are adapted to contact said plates on those broadsides which are remote from each other and to convey said plates in said direction of travel.

Abstract: A process for the preparation of catalysts, in particular for the purification of exhaust gases from internal combustion engines, is described, which makes it possible to use supports stable up to at least 1,200.degree. C. which are free of gamma-aluminium oxide and transition aluminium oxide and nevertheless have a high catalytic activity. The catalytically active noble metal as the constituent of a composite powder is attached to the support, which in addition to the noble metal contains a thermally stable metal oxide and is prepared by the spray pyrolysis process.

Abstract: A device for adjusting the belt length in a safety belt system comprises a frame and a winder element rotatably journalled thereon, from which the belt may be unreeled, upon actuation of a key, against the force of a spring and on to which it may be wound again automatically by the force of this spring. To ensure the immobilization of the belt at its required length, the winder element interengages with a lock releasable by the key.
