Abstract: ABSTRACT A closure cap (1) of plastics material has a circular sealing lip (5) which is arranged in the region of the join (6) between the cap wall portion (3) and the cap end portion (4), and points inwardly at an inclined angle. At its smallest diameter, the sealing lip has a rounded sealing portion (7). Below the sealing portion, the sealing lip is enlarged outwardly in a funnel-like configuration, to receive the mouth (2) of a container. By virtue of that arrangement, a reliable sealing action is produced at the outside wall portion (8) of the mouth (2) of the container, even when there are large fluctuations in tolerances. In each case, the sealing region which extends circularly around the mouth of the container is of a linear configuration, which considerably enhances the sealing action of the sealing lip.

Abstract: ABSTRACT:       The invention relates to a disc player for a rigid information-carrying disc, which player has a disc holder on which the disc rotates during information transfer, the disc holder comprising a turntable and a centring  device, which device comprises a plurality of centring elements which are arranged along a circle, which are each resiliently movable in a radial direction in order to keep the disc centred during rotation by means of the centring elements which act on the wall of the centre hole in the disc.  A lid which is movable from an open to a closed position in two stages carries a disc loader and is coupled to lifting means.  After the disc loader has resiliently urged the disc onto the centring device and the turntable in a first stage, the lifting means lift the lid in a second stage until the disc loader is clear of the disc which is clamped on the centring device.  The resilient centring elements firmly retain the disc on the turntable as a result of their radial elastic deflection.

Abstract: ABSTRACT      The method and improvement for recovery of hydrocarbons in situ from subterranean oil shale formations is disclosed by forming generally horizontal electrodes from the injection of molten metal into preheated or unheated fractures of the formation.  A nonconductive spacing material is positioned in the casing of the bore hole between the electrodes.  A fracture horizontally intermediate between the metallic electrodes is propped with a nonconductive granular material.          Unterminated standing waves from a radio frequency (R.F.) generator are passed between the electrodes so as to heat the oil shale formation.  The hydrocarbons in the formation are vaporized and are recovered at the surface by their migration through the intermediate fracture and tubing.  By this method radial metallic electrodes can be formed at various depths throughout a subterranean oil shale formation so as to vaporize the hydrocarbons contained within the oil shale formation.

Abstract: ABSTRACT         In Conform machinery for continuous friction actuated extrusion the wheel is made up of at least three parts, namely two cheeks with a hub between them.  Annular coolant passages extend between these members and are fed by ducts which extend at least through the cheek members.  These ducts (and any extending through the hub) are lined with thermally-insulating material such as PTFE.  This greatly reduces thermal stresses around the coolant ducts, which can be a cause of premature and catastrophic failure of the wheel.

Abstract: COLLECTOR     ABSTRACT   A collector for the results of a pipelined central processing unit of a digital data processing system.   The processor has a plurality of execution units, with each execution unit executing a different set of instructions of the instruction repertoire of the processor.   The execution units execute instructions issued to them in order of issuance by the pipeline and in parallel.  As instructions are  issued to the  execution units,  the  operation code identifying each instruction is also issued in program order to an instruction execution queue of the collector.  The results of the execution of each instruction by an execution unit are stored in a result stack  associated with each execution unit.          Collector  control  causes  the  results  of  the  execution  of instructions  to  program visible  registers  to be  stored  in  a master safe store register in program order which is determined by the order of instructions stored in the instruction execution stack on a first-in first-out basis.  The collector also issues write commands to write results of the execution of instructions into memory in program order.

Abstract: PIEZOELECTRIC REED POWER SUPPLY FOR USE IN   ABNORMAL TIRE CONDITION WARNING SYSTEMS                Abstract A device is provided for sensing the condition of a pneumatic tire preferably of the type used on an automobile wherein the tire is mounted on a tire rim and the tire is subject to normal vibra-tions.  The device comprises a housing, a means for mounting the housing to the tire rim, sensing means for monitoring the condi-tion within the tire, circuit means operatively connected to the sensing means for generating radio signals indicative of the tire condition, power supply means operatively connected to the circuit means and means for receiving the radio signals.  The power supply means includes a piezoelectric reed having a base portion and an end portion.  The base portion is elastomerically bonded to the housing. A tuning mass member is mounted to the end portion and is configured for mating abutment against stop members which limit the flexure stroke of the piezoelectric reed and inhibit compound bend- ing of the reed.  The tuning mass member includes an outer weighted casing and an inner elastomeric portion insulating the reed from physical shocks to the outer casing and from electrical shorts across the casing.  The tuning mass member is sized relative to the piezoelectric reed to obtain a resonant frequency of vibration of the power supply induced by common road vibrations during wheel operation.  The reed is symmetrically configured about a radiating center line of the tire.
