Title: Linkage to raise and lower surface skimmer of decantation tank - is actuated by low pressure pneumatic jack pref. rubber bellows
Inventor: DUROCQ LOUIS
IPC: B01D21/18
Filed: 1980-06-27
Abstract: A power linkage for raising and lowering the skimming rake used to sweep surface scum from a rectangular or semicircular decantation tank. The tank is of the type in which the rake is mounted on a mobile chassis which bridges the tank and moves in one direction with the rake lowered to sweep the liq. surface and then back again with the rake raised to an inactive position. The rake is raised and lowered by a power linkage using an actuating jack. An air compressor serves an emulsion pump for shifting sludge from the bottom of the tank. The rake linkage actuating jack is now a pneumatic jack operated by low pressure air from the compressor serving the emulsion pump. The air pressure is pref. less than 0.4 bar and the pneumatic jack comprises a simple, deformable container made of resilient material, e.g. a corrugated, rubber bellows. Pref. as the mobile bridge chassis reaches each end of its travel, a pneumatic limit switch is triggered so that a pilot valve actuates the pneumatic jack. The skimmer is used to clean the top surface of liq. being treated in a sedimentation tank.

Title: Cooling circuit for refrigerator - has hinged condenser acting also as enclosing grille for circuit
Inventor: BIANIC CHRISTIAN
IPC: F25D23/00
Filed: 1980-08-01
Abstract: The refrigerator has a storage compartment (2) with a recess at the back with the external components such as the compressor (4), the condenser (5) and possibly a fan housed in the recess. The condenser is designed to form a part of the component enclosure. The condenser is hinged along its horizontal axis (13) and connected to the compressor by a curled pipe (15). This renders the connection flexible to allow the condenser to be opened to gain access to the other components. The condenser thus acts as a ventilation grille, a protection grille and as part of the enclosure.

Title: Digital switching for telecommunications conference system - uses processor to control ports for routing data to required destination
IPC: H04M3/56
Filed: 1980-11-21
Abstract: A conference system for telecommunications terminals operating in a simultaneous bidirectional mode is realised by use of a digital switching system. A processor effects the read or write operations of the data on a bus line. Telephonic speech is sampled to form digital data frames for transmission on a number of channels. A number of terminal circuits receive the data via ports and a time division multiplexed data bus permits exchange of the data or a sequential sharing basis. Memory circuits record the selected data frames and a processor controls the ports to effect read and write operations into the memory. This allows the selected data to be routed in an output signal to the ports for the appropriate destination.

Title: Remote controlled rotary head with tool holder slide - is driven during rotation by reciprocating ball train in hydraulic loop
IPC: B23B29/034
Filed: 1981-01-27
Abstract: The remote controlled rotary heads adapt to a machine-tool table with revolving spindles, using a head (I) with an integral tool-holder slide. It can transmit reciprocal linear motion to the slide whilst the head rotates, the movements being initiated from an independent control centre through a network of supple pipes and a rotatable coupling. The head may include two passages each locating a ball (1) train driven by floating pistons (2) in a closed hydraulic loop. The ball trains drive independent wheels (W) on an output shaft (S), final linear drive being imparted by worm and wheel or rack (R) and pinion (P). The hydraulic circuit may include two pressure compensators with fixed adjustable stops, the shaft also being drivable by a crank handle or a servo-motor.

Title: Electrical heating cartridge with coaxial internal heat transfer tube - to minimise temperature differentials at the cartridge tip
IPC: H05B3/46
Filed: 1981-08-26
Abstract: An electrical resistance heating cartridge comprising a tubular body ending in a relatively sharp nose and having resistance windings surrounding a coaxial ceramic core includes a "heat-tube" located coaxially partly within a passage coaxial within the ceramic core and partly in an extension of the passage within the tip of the cartridge casing. (the "heat tube") is a tube conductive material, e.g. Cu, Ni, Al or stainless steel contg. steam or gas at reduced pressure to act as a heat transfer agent within the tube from one end to the other - may also be known as a "thermal tube", a "caleoduc" or a "caloduc"). Used esp. for cartridge heaters for use in thermoplastic processing equipment to heat injection moulding rubbers, extruder cores or "torpedoes", welding tools, for liquid-filled plastics beach balls, bowls, etc. The inclusion of the heat tube reduces temperature differentials between the cylindrical surfaces of the cartridge and its tip from 25 deg.C or more to 5 deg.C or less.

Title: Processing circuit for colour TV camera detector - uses analyser to produce colour signals for each point of matrix detector
Inventor: MORAILLON JEAN YVES
IPC: H04N9/04
Filed: 1982-02-19
Abstract: An analyser (10) output is multiplexed (51) with a constant coefficient (KA,KB,KC) which depends on the colour of the filtering element at a point matrix detector. The multiplexer is operated at half the detector reading frequency. Its output is passed through a high pass filter (24a) to a rejection filter (61) to reject the parasitic sampling frequency. The analyser output is demultiplexed (12) to provide one output which passes directly to a low pass filter (17). A second output is applied to multiplexers (26,28) with a delayed (31) output. The outputs pass through low pass filters (35,39) and all the filter outputs are summed (16,34,38) with the rejection filter output to obtain single colour (A,B,C) signals.

Title: Secure interconnection system for shared data transmission - uses local auxiliary buses for connection of processors and peripherals through couplers to bus-loop
Inventor: LALLEMENT PHILIPPE
IPC: H04B1/74
Filed: 1982-05-25
Abstract: A functional unit comprises a processor card and two peripheral cards while a second functional unit comprises a processor card and a peripheral card. These are interconnected by a general bus and in order to prevent failure of a card from blocking the bus a safety interconnection circuit is used. This comprises an auxiliary bus to which processor cards are connected through a bus coupler. A second coupler type is used for peripheral cards. Couplers of the same functional unit are connected to a local auxiliary bus. A local repeater connects the local auxiliary buses to an auxiliary bus loop which interconnects all local repeaters through loop repeaters. The auxiliary bus permits reconfiguration of the system and allows a faulty card to be disconnected.
