Title: Liquid cooled multi-disc friction brake or clutch - has improved axial coolant flow for increased heat exchange provided by pair of cutaways
IPC: F16D13/72
Filed: 1974-11-12
Abstract: Basically circular friction plates are provided with curved sections of friction material on either side. Two parallel flats on the edge of the discs reduce their axial area. This creates an increased cross sectional area for the axial flow of cooling liquid inside the housing. A variation to parallel flats is obtained by providing the friction plates with two or three concave cut outs. This configuration produces less scrap when the discs are punched from strip material. The disc may alternatively be formed in an approximate Y-shape by producing the cut outs as curved punched out edge sections, or a pair of smaller facing cutouts spaced between two large cutouts.

Title: Control system for cintral heating installations - uses gas or liquid fuel and can be programmed on weekly basis
IPC: F23N5/14
Filed: 1974-11-25
Abstract: The control system consists of two discrete parts. The first is operated from two resistances of a Wheatstone Bridge and has one resistance sensitive to external temperatures. The second sensitive regulates the internal temperature of the building according to a weekly, daily and hourly programme. This control operates the circulating pump through a day and night thermostat. The system is connected to an electrical clock so that the controls and temperatures may be set the required figures. Two separate resistances control the burners to the boilers on or off as required. The system may be adapted to a number of installations in parallel.
Patent FR-2296796-A1 (FR)
Title: Transmission system for moped - with automatic high ratio selection for starting
IPC: F16H61/662
Filed: 1974-12-31
Abstract: One half of the pulley (3) slides on the motor shaft (1) and carries a helical track (15) bearing on a fixed roller (7). The other half of the pulley (4) can rotate but not move axially on the motor shaft. If the sliding half (3) is rotated by the belt (2), the track (15) rides on the roller and drives the sliding half pulley towards the fixed half, automatically increasing the drive belt radius and producing a higher gear ratio. Spigots (11, 12) and a stop (8) fixed to the motor shaft ensure that the gear change happens in about one half revolution of the pulley. When the motor starts, the action is reversed and a spigot (13) on the free half (4) of the pulley engages with another spigot (10) on the motor shaft to ensure that both halves of the pulley are driven.

Title: Prodn. of animal fodder with balanced protein to carbohydrate ratio - by growing yeast etc. in a base carbohydrate-contg. fodder
IPC: A23K1/00
Filed: 1975-04-04
Abstract: Prodn. of protein material for use in making fodder with a balanced protein/carbohydrate ratio, consists of growing a carbohydrate-contg base fodder in a liq. and making a fodder substrate with a base fodder fraction 'K' (dry solids) and several parts water, inoculating this substrate with yeast or other micro-organism and growing the organism to give an edible substrate. Method gives high quality fodder, and provides a chep process for making the protein. The prod. has lower moisture content than e.g. silage, and thus can be kept for longer periods.
Patent FR-2268315-A1 (FR)
IPC: G07D9/00
Filed: 1975-04-17
Abstract: 1486519 Identifying and counting coins NGZ GELDZAHLMASCHINEN GmbH & CO FERTIGUNGS-KG 9 April 1975 [19 April 1974] 14551/75 Headings G4V G4X and G4D Apparatus for identifying and counting coins comprises an optical signal transmitter controlling a counter in which the signal transmitter is formed by an optico-electronic image converter past which the coins are adapted to be guided and which supplies signals representative of the respective coin surfaces, the said signals being fed to a comparator which in its turn feeds the counter with signals associated with the coins. Coins are fed from a trough 13 to a rail 15 by conveyer 14. A rocker member 16 permits coins to pass to rail 18 when in a closed position but when open coins fall on to conveyer 17 and are passed back to the trough. Coins passing along the rail pass image converter 19 consisting of four solar cells 20. A light source 21 projects rays through a condenser 22 to the solar cells. From the rail coins pass through shoot 23 into distributor shoot 24 and thence into through one of passages 27 into a container 29. Shoot 24 is positioned by a step-by-step mechanism 26. Fig. 2 shows how rocker member 16 is rotated to an open position by magnet 38 when it receives a signal from photo-electric cell unit 36 via store 37, that a coin has passed. The member 16 is closed when the counting operation in respect of a coin is completed. When a coin passes image converter 19 there is a decrease in the output voltage of a summation or adding unit 39. If the value is below an adjustable reference level comparator 41 prepares for an evaluation instruction. This occurs when the solar cells 20c and 20d are covered by equally large amounts which causes zero-pasage discriminator 42 to pass from a low level to a high level position. After delivery of the evaluation instruction store 37 is returned to its initial position. Also by means of an eight-channel analogue comparator 43 and a coder 44, a channel number is fed into an intermediate store 45 when there is voltage parity between the output voltage of summation unit 39 and a reference level adjusted by reference level adjusting unit 31. The reference levels correspond to the normal dimensions of the coins of a coinage system. The channel numbers are supplied to a counter 46 which has a valuation stage, an adding mechanism 48, a store 49 and an indicating means 50. A metal senser 51 prevents the use of counterfeit coins. For coin sorting, the difference between a channel number which is stored in an intermediate store 45 and the counter content of a forward and backward counter 54 is determined in a comparator stage 53. Depending on the difference an instruction is given to control means 55 of mechanism 26.

Title: Protecting underwater steel units against corrosion and fouling - by covering plastic insulator jacket with metal, pref copper
IPC: B01J19/00
Filed: 1975-04-25
Abstract: Steel structural units for underwater use, esp. ships and pipes, are protected against corrosion and fouling, by plant or other growth, by applying a metallic anti-fouling agent, surrounding steel unit entirely or in part, on an electrically insulating layer coating the surface of the steel unit. Long-term protection is given; anti-fouling protection lasts for several years and can be renewed without lifting steel units out of sea-water, drying and repainting. Insulating layer pref. consists of a plastic, e.g. polyethylene, and anti-fouling agent of Cu or a Cu alloy, used as a wire, strip, foil, mesh, paint or sprayed-on powder.

Title: Hydrostatic transmission for small vehicle - with hydraulic brake to stop gear shaft for gear change
IPC: F16H3/12
Filed: 1975-07-17
Abstract: The mass produced small vehicle has a combustion engine which drives a fluid flywheel. This in turn drives a single speed gear bos, which has the facility for reverse and neutral settings. In order to provide a simple gear change control the main shaft (4) of the gear box is braked during gear change. The gear brake operates from the hydraulic brakes of the vehicle, but at a lower pressure than is required to apply the wheel brakes. A pressure control system isolates the gear change brake from the wheel brakes when a set pressure is exceeded.

Title: Appts. for drying and superheating steam, e.g. from nuclear reactor - incorporates tubular enclosure with deflectors imposing helicoidal movement of flow, increasing compactness and efficiency
Inventor: CERDAN JEAN-PIERRE
IPC: F22B37/26
Filed: 1976-07-05
Abstract: A steam drier and superheater comprises a tubular enclosure connected to a superheating pipe. Satd. steam enters through one end of the tubular enclosure, in which there are means for deflecting the flow and extracting the liq. phase. The means of deflecting the flow are placed near the upstream end. They cause it to take the form of a single stream and impose a rotation, e.g. helicoidal, motion. The means of extraction are placed so as to collect the liq. phase which gathers on the wall of the enclosure, and to discharge it. Used in drying satd. steam from e.g. boiler, a nuclear reactor or a heat exchanger. Compared to existing drier/superheaters the appts. is more compact, carries out both operations of drying and superheating more efficiently and permits high flow rates with acceptable pressure drops.
