Title: Rotor balance system for compressor motor - has throat surrounding counterweight support of rotor end ring to withstand discontinuous rotational movements
Inventor: MOODIE ELDON EUGENE
IPC: H02K7/04
Filed: 1979-03-29
Abstract: The dynamo electric machine rotor has conducting material end ring designed to form a circuit for the rotor current. The end ring or rings (15, 17) have a surface (19) approx. perpendicular to the rotor axis of rotation. A counterweight support (21, 23) forms parts of hte end ring (15). The support projects w.r.t. the surface (19) of the end ring so as to receive a balancing counterweight (25-31). The end ring surface (19) has a throat (33) which surrounds the counterweight support. An internal edge of the throat progressively connects the ring surface to the counterweight support. This connection gives to the counterweight support structure which enables it to resist the forces applied to it during discontinuous rotational movements of the rotor.

Title: Low head hydraulic turbine - has pistons reciprocating in cylinders to pump water onto turbine nozzle
IPC: F03B17/00
Filed: 1979-03-29
Abstract: In the device two cylindrical reservoirs contain water. A piston reciprocates in each reservoir and pistons are linked so that as one rises the other falls. There is a valve in each piston which closes on the downstroke and opens on the upstroke. On the downstroke the piston compresses the water and forces it from the bottom of the reservoir through a tube leading to a nozzle. The same nozzle is served by the tubes from both reservoirs. Water issuing at pressure from the nozzle rotates a turbine and then returns to the top of the two reservoirs.

Title: Audio-visual educational game for children, has signals extinguished or silenced by correct association of paired pictures
IPC: A63F9/18
Filed: 1979-04-27
Abstract: The frame (201) supports two sets of pictures, each picture in the second set being associable with one in the first set. The game is won by the first player to choose from the second set the picture which is correctly associated with a picture in the first set, which thereupon disappears from the display (or alternatively the accompanying sound effect is interrupted). The game resembles a game of chance such as roulette, in which the wheel may rotate randomly in either direction with abrupt stops, and is represented by flashing lamps (9), one of which eventually remains alight.

Title: Mfg. self-lubricating seals as long laminated strips - by co-vulcanisation of extruded composite strips to fit large paper mfg. rolls etc.
IPC: B29C48/475
Filed: 1979-05-04
Abstract: Elongated seals of self-lubricating material are made by extrusion of a solvent-based suspension of rubber, solid lubricants (graphite; MbS2) and refractory fibres through a strip die and subsequently laminating and co-vulcanising two or more superimposed strips in a heated press tool. Used for mfr. of seals used within large suction rolls used for paper mfr. e.g. those mounted against the underside of the roll face. Process produces longer one-piece seals than those available from sheet formed around the circumference of a calendar roll. Interlayer adhesion is better than that of multilayer seals cut from sheets individually vulcanised and/or consolidated from different materials, e.g. rubber, asbestos or ceramic fibres alone.

Patent FR-2429900-A1 (FR)
Title: Fuel injection nozzle for diesel engine - has ring under tension applying compressive force outside annular fuel supply groove
IPC: F02M61/10
Filed: 1979-06-27
Abstract: A fuel injection nozzle assembly for a diesel engine has the nozzle and the needle spring housing screwed together by a sleeve. As the fuel is injected from the pump tension stresses are set up in the body (12) in the region of the annular groove (24). This stress is minimised by shrinking on a ring (26) so that the body is in the free state, under a compressive stress. The ring forms the abutment for nozzle in the threaded sleeve holding the assembly together. Alternatively the ring could be of a wedge section that corresponds to a tapered face on the nozzle outside in the region of the groove, so that when the assembly is screwed together the ring wedges on the nozzle and exerts a compressive stress.

Abstract: The ring for blowing soap bubbles consists of a circular frame (1) made from a smooth tube of plastics. The extremities of this (10a,10b) are fitted on to a joining piece (4) which joins it to a handle (2). The diameter of the ring is between 25 and 35mm and the external diameter of the tube is between 5 and 7mm. The joining piece is curved to correspond to the shape of the ring and has projections (6a,6b) which fit into the extremities of the tube and into the handle (7). Alternatively it can have holes into which they fit.
Patent FR-2433816-A1 (FR)
IPC: G21F9/34
Filed: 1979-07-24
Abstract: A plurality of containers (1) with irradiated fuel elements or other radioactive material are stored in the tubular shafts (5). The tubular shafts (5) are joined together movably by means of mandral guides (8, 9) which are welded onto the guide ribs (2). The mandral guides (8, 9) permit the heat expansion of the tubular shafts (5), independently of each other in the vertical direction. The space (10) formed between the container bottom (13) and the store bottom (12) serves in each case as a flow chamber for the cooling medium which flows through the cooling ducts (6) formed by the guide ribs (2). The tensions in the storage rack are eliminated by the possibility of vertical expansion of the tubular shafts (5) and by the improved flow conditions.

Title: Plug for deep undersea pipeline with pyrotechnic gas-generating charge - which brings about sealing off against high pressure, preventing flooding of pipeline in case of accident during laying
IPC: F16L1/235
Filed: 1979-11-02
Abstract: Device for closing off deep undersea pipelines in case of accident during laying which could cause flooding of the pipeline comprises an autonomous pressure generator, means of detecting accidents to the pipeline, mechanical means of circulation without friction in the pipeline and a seal ensuring water-tightness. The seal is constituted by a skirt in polyurethane which will be deformed and applied against the inner wall of the pipe by the expansion of a water-tight annular chamber. It possesses a central armature with supports to take up the flexibility of the skirt, and annular pockets between the central armature and the skirt. The seal is connected to a gas generator contd. in a receiver resistant to high pressure. The gases are cooled before they reach the inflatable annular pockets. A closing-off system pref. comprises two such devices connected by a cable and situated on either side of the zone where the damage can appear, e.g. the most curved part. The invention overcomes difficulties encountered with existing internal mobile pipeline closing-off devices, held by a rope from a ship to the horizontal part of the pipe, in which the closing-off mechanism is controlled by an electrohydraulic group integrated in the plug and activated by a detonator. These devices are not suitable for the pipes of small dia. used for great depths. They do not prevent the flooding of the suspended part of the pipeline connected to the laying vessel. They risk being displaced by the propagation of the crushing to the next buckle arrester and sliding in case of failure of their clamping mechanism.

Title: Gold ingot checking device - comprises mould having internal dimensions matched to ingot and weight equal to that of ingot
IPC: G01B3/30
Filed: 1980-02-06
Abstract: The system checks the carat of a piece of gold and is intended to check both the volume and the weight, thus in effect checking density. For a cylindrical gold ingot (11) the device is made as a cylinder of copper (12). The internal dia. of the cylinder (D) is the same as the correct external dia. of the ingot so that a correctly formed ingot should fit without play. Similarly the length (L) of the cylinder is intended to match the correct length of the ingot. By choosing an appropriate thickness the copper cylinder is made to have the same weight as the corresp. gold ingot, so that the two may be compared on a balance. Moulds of other shapes may be formed for ingots, bars or coins of other shapes. A flat mould may for example include a cut-out shape and a slot for checking area and thickness of a gold plate.
