Title: Vacuum deposition of layers through masks - changing the masks under vacuum
Inventor: TUETA ROGER
IPC: C23C14/04
Filed: 1981-09-30
Abstract: Flat electro-luminescent screens etc., are produced by vacuum deposition, through masks, of a number of different layers. The sample to be coated is located in a carrier, which can be rotated in a vacuum chamber. On the carrier is mounted a disc, around which the masks are cut. When the carrier is stopped, in the right position in the chamber, a rod may be engaged with the axis carrying the disc. The disc can then be rotated to position the required mask over the sample. The rod is retracted and the mask is held against the sample by a spring. It is located by an indexing peg on the carrier engaging in a hole in the disc. Changing masks without releasing the vacuum and opening the chamber considerably reduces changers of pollution at the interfaces of the layers. It also saves time.

Title: Volumetric perfusion pump for medical use - has identifier for liq. sensed by detector associated to pump and electronic controller to establish related fluid flow variations
Inventor: JEANMOUGIN MICHEL
IPC: A61M5/142
Filed: 1981-10-16
Abstract: The tube (I) is filled with a perfusion liq. from an upper reservoir or bottle. A part (Ia) of tube (I) forms a pump body. A motor drives the liq. mechanically through the pump body (Ia). Tube section (Ia) is located between two discs, and the disc on the output side of the section (Ia) is located in a detector, which monitors the vol. of the perfusate being delivered at the output end of tube (I). The detector feeds signals representing the actual vol. delivered to an electronic controller, which can adjust the actual vol. to coincide with a pre-recorded desired vol. The pump is used for the medical treatment of humans.

Patent FR-2493399-A1 (FR)
Title: Control of fuel supply in internal combustion engine - has transducer which provides series of signals at predetermined positions of rotary part of engine, through shaping circuit
Inventor: TUMBER BRIAN WILLIAM
IPC: F02M41/14
Filed: 1981-10-28
Abstract: The system includes an electromagnetic device (52) which when energised causes an increase in the amount of fuel supplied by a fuel pump forming part of the system, to an associated engine. A transducer (54) which provides series of signals at predetermined positions of a rotary part of the engine, is provided, the signals being supplied through a shaping circuit (55) to a delay circuit (56) which provides a signal of fixed time length to a second circuit (58) to deenergise the device (52) every time a transducer signal is moved. As the engine speed increases therefore the amount of fuel supplied by the pump decreases and vice versa. The delay circuit is adjustable by the engine operator so that he can exercise some control over the quantity of fuel supplied by the pump. A third circuit (57) provides a continuous signal to de-energise the device if the interval between pulses from transducer becomes excessive.

Title: Rotary hydraulic damper with temp. compensation - uses change in gap between rotor and stator to compensate for change in damping from silicone oil in stator
Inventor: ROTH SIEGFRIED
IPC: G01D11/12
Filed: 1982-03-10
Abstract: The hydraulic damper comprises a stator (2) consisting of a cylindrical sealed aluminium case which houses a solid or hollow cylindrical PTFE rotor (3) which extends to almost the full length of the housing. A narrow annular clearance (4) exists between the stator and rotor and is filled with a silicone oil damping fluid. The rotor is supported at the open end of the stator by a roller bearing assembly (5) to which the rotor is attached by a locking nut (6). A cover (7) screwed into the open end of the stator closes the assembly but allows a shaft (9) to pass through for coupling to the rotating element requiring the damping action. In operation over a temp. range, the clearance increases with temp. but the damping force remains constant.

Title: Isolating valve for dual circuit automotive braking system - uses piston with passages for each braking circuit to block off low pressure circuit if failure occurs
Inventor: BERTIN PATRICE
IPC: B60T11/32
Filed: 1982-03-19
Abstract: The isolating valve for a double circuit automative braking system, has pressure comparators fitted between the two circuits to isolate the circuit having low pressure when a significant pressure difference is detected between the circuits. It also has a body (17) having a passage (18) with four orifices: a first service orifice (19) associated with a first pressure orifice (20) and a second pressure orifice (22) associated with a second circuit (13,15). A piston (23) sliding in the passage defines two chambers (24,25). A bi-directional spring mechanism (26) tends to maintain the piston (23) in its equilibrium position, with the two inlets connecting to the two outlets, respectively. A pressure differential between the chambers (24,25) displaces the piston along the passage, blocking the outlet passage in the low pressure circuit, and allowing a spring loaded finger (38) to lock the piston. An electrical contact for a warning lamp is associated with the locking finger.

Patent FR-2522367-A1 (FR)
Inventor: ISOYA YUKINORI
IPC: F02M15/00
Filed: 1983-02-23
Abstract: A variable venturi carburettor with a carburettor housing, a float chamber and a main fuel nozzle is equipped with a chamber, through which fuel flows, arranged in proximity to the main fuel nozzle for cooling of the main fuel nozzle and of the carburettor housing in that the fuel delivered from a fuel pump to the float chamber is fed wholly or partially through the cooling chamber. By means of this arrangement according to the invention, an increase in the temperature of the fuel in the main fuel nozzle is prevented, thereby preventing the occurrence of fuel vapour in idling operating of the engine and any influencing of the rate of fuel flow in the idling fuel duct. Fluctuations of the air-fuel ratio when the engine is in idling operation are thereby suppressed.
