Title: Adjustable mounting ensures constant face contact loading betw gears - has axial drive gear motion while ball coupling bar retains radial position
IPC: F16H57/025
Filed: 1975-05-07
Abstract: The contact between an output gear (1) of a drive unit (2) and another tak-off gear is regulated by a dumped torsion bar arrangement. The bar (6) provides a flexible link between a flange (4) fixed rigidly to the drive housing at one end and a flange (4) rigidly attached to a separate machine body. Ball profiled (11) sleeves are retained between guide flanges (5, 7) mounted on a common backing plate. The ball sleeves located in mating bushes (12) that are retained in the main flanges (4). The complete drive unit is mounted on vibration absorber pads (10) of the elastomer type that limit axial motion. The complete assembly permits axial motion to occur, but ensures that radial displacement between the drive and take-off gears is maintained constant.

Title: Laser equipped multipurpose sensor for geological research - measures gravity using laser levitation method and homogeneity using laser interferometry
IPC: G01S17/87
Filed: 1975-06-09
Abstract: A portable measurement sensor (1) for mineral research measures discontinuities, defects and variations or homogeneity of materials. It comprises a laser transmitter (10) and detectors together with ultrasonic and infrared equipment (11). A device for gravity measurements uses a laser beam to lift fine particles, pref. metallised, inside a partially evacuated enclosure. The height to which the particles are lifted depends on the gravity to which they are subjected. Another device (9) determines homogeneity by bringing a helium saturated atmosphere into contact with the surface of the material investigated. Laser interferometry gives the thickness of the liquified gas film on the surface.

Patent FR-2307209-A1 (FR)
Inventor: HAMBURGER NICOLAS DR
IPC: F15B13/043
Filed: 1976-04-07
Abstract: Good linearity between the electric current and the displacement of the control spool, good dynamic behaviour and low susceptibility to faults are to be achieved with the proportional valve. A plunger (7) is suspended in a longitudinally displaceable manner in the electromechanical transducer (2) by means of two spring members. The plunger carries a permanent magnet in the centre and passes through two exciting coils arranged fixed to the housing on either side of the permanent magnet. The control spool (5) is designed as a follow-up piston opposite an end face (8) of the plunger, the follow-up control being effected by means of a nozzle (9) located at a distance from this end face and firmly connected to the control spool. A control flow diverted from the main hydraulic flow passes through this nozzle (9).

Title: Correcting agent for flour derived from problem wheat - contg. cystine and ascorbic acid
IPC: A21D2/28
Filed: 1976-04-21
Abstract: A correcting agent for flour contains ascorbic acid and cystine. Also flours which are difficult for bread making are corrected by adding the above so that flour contains 20-100 ppm of cystine. The cystine/ascorbic acid ratio is from 1:5 to 5:1, particularly from 1:2 to 2:1. The correcting agent pref. also contains 1-8, esp. 2-6 pts./pt. cystine of a phosphate, esp. a calcium phosphate. A flour contg. even 20% flour derived from "problem" wheat such as the high-yielding Benno, Kranich and Feldkrene species gives a mobile, sticking dough, which on baking rises too little and gives bread with incomplete development, reduced volume and unsatisfactory structure. The above agents gives satisfactory bread from flour contg. above 20% and particularly above 50% problem flour.

Title: High frequency welder driven from low voltage direct current source - suitable for sealing medical packs from a standard vehicle electrical system
Inventor: GARDE BERNARD PIERRE GEORGE
IPC: H02M7/537
Filed: 1976-05-21
Abstract: High frequency welding jaws can be driven from a low voltage DC power source by means of an oscillator used in conjunction with an amplifier and an ancillary circuit which shits the impedance of the oscillator output terminal relative to the impedance of the input terminals of the electrodes. Used for operating equipment at e.g. 140-175 MHz, 80 Watts and 800 V for welding package seams, viz sealing (PVC) sample sachets or tubes of blood donor samples or equipment using mobile power, viz from vehicles restricted to typical 12 V accumulator power sources with an effective operating potential of 9-10V. This eliminates need for connection with fixed high voltage (200-250V) power supplies, or relatively bulky and expensive alternator/transformer combinations or extra accumulators. Power requirements are approx. half that drawn from conventional systems during welding and need not be sustained between welds.

Patent FR-2353715-A1 (FR)
IPC: F02B37/00
Filed: 1976-08-09
Abstract: In the ship's propulsion system with a supercharged diesel engine (1) a waste heat boiler (10) is connected to the outlet of the exhaust gas turbine (6) of the turbocharger.

Title: Lining device for confectionery and pastry moulds - with platform turning through 180 degrees to drain off excess lining material
IPC: A23G3/20
Filed: 1976-11-18
Abstract: The device comprises a platform moving around a horizontal axis above a tank. One face of the platform is provided with cavities; these receive the moulds adn any excess of the lining material drains away when the platform is turned over. The platform turns around the axis fixed above the tank. The cavities receive the mould which are held in position by the grid; the plate slides on teh base of the tank. Handles allow the platform to be monoeuvered around the axis and to be held in the horizontal position when they rest on the lateral sides of the tank. When the moulds are lined with the coating substances, e.g. chocolate or sugar, and after placing the grid in its channels, the platform is turned over through 180 degrees to the horizontal; excess coating drains out on to the plate and only a film remains inside the moulds. A great saving in time and manual labour is effected as compared with the brush application method.

Title: Continuous distribution ground baiting appliance - disperses bait from block of ice, and parts are recovered for use again
IPC: A01K97/02
Filed: 1977-02-25
Abstract: The fishing bait release device has a tube (1) hermetically sealed near one end by a cork to which a coil of wire or nylon is attached. The tube is placed over a boss in the bottom of a pot, hermetically sealing the lower end of the tube. A boss on a pot cover centres the tube in the pot. The pot is filled with bait and water and is frozen solid. In use the cover and pot are removed and the wire is connected to a ballast (17) using a paper clip (12). One end of clip (12) is inserted in a piece of macaroni (13). The macaroni softens in the water so that when the bait has dispersed the buoyancy of the cork causes the clip to free itself for recovery and re-use of the tube and wire.
