Patent FR-2492891-A1 (FR)
Title: Charge intake for IC-engine - has housing with air flow passage controlled by obturator and fuel passage with sprung valve
IPC: F02M69/28
Filed: 1980-10-24
Abstract: The air intake for an i.c. engine has a housing (1) containing an air flow passage (2). An orifice feeds fuel (8) under light pressure to the passage intake to mix with the air. A valve (9) can close the fuel orifice via a spring. A feed control valve (19) has a gate (26) in the air passage and over the fuel inlet. A spring (24) forces the gate closed and is mounted in the base of the housing. A second valve (35) can control the volume of the housing depending on external conditions.

Title: Device for resolving ambiguity in pulse radars with variable repetition frequency
Inventor: GERARD THOUVENEL
IPC: G01S13/524
Filed: 1981-01-19
Abstract: A pulse radar with variable repetition frequency producing measurements marred by ambiguity and uncertainty comprises means for modifying the repetition frequency in order to produce series of ambiguous measurements corresponding to different values of ambiguity. A specific Kalman filter (251) is allocated to each of the possible states for the radar-target system at the beginning of an iterative measuring process. An unambiguous estimator is thus produced at the output (271) of each of the said Kalman filters for each successive ambiguity value. A measurement of likelihood produced at the output (441) of a module (40) is associated with this estimator in order to determine at the end of each step the probability that the corresponding filter (251) has been correctly initialised. A selector interrupts the iteration when this measurement of likelihood reaches a predetermined threshold for one of the filters whose output (271) then supplies unambiguous values of the required state parameters. Applications to measurements of distance/speed in coherent pulse Doppler radars with variable repetition frequency.

Title: Sheet offset printer with electronic-pneumatic rectification - has microprocessor control from optical detectors with sheets constantly supported during rectification and margin setting
IPC: B41F21/00
Filed: 1981-09-17
Abstract: The machine has pneumatic and electronic systems for rectification and margin setting. An arrangement of cylinders permits the transfer of fully finished printed sheets, by use of a pressure cylinder of doubled diameter. The cylinder has two arcs of a circle of 145 degrees on its circumference. A microprocessor with optical detectors commands and controls the pneumatic and electronic systems. The sheets are constantly pneumatically held during rectification and margin setting until complete closure of the pressure cylinder grips.

Title: Hydraulic picking mechanism - using pair of synchronised hydraulic cylinders with accumulator forming oscillating, energy-conserving system
IPC: D03D49/42
Filed: 1982-01-20
Abstract: A picking mechanism comprises a pair of double-acting hydraulic cylinders, one on each side of the loom, the movements of the pistons being synchronised by means of a data processing control unit such that they provide a coordinated picking and checking mechanism. Each of the cylinders is connected to a system of reservoirs or accumulators having a natural period of elastic oscillation which corresponds to the pick-insertion rate, whereby most of the energy for picking is stored and constantly re-used, only losses due to internal resistance requiring replacement. A slide valve controlled by the processing unit connects each cylinder alternately to the accumulator and then to a power source to top up the pressure at appropriate points of the cycle. This is a simple mechanism with few moving parts which gives relatively slow, impact-free acceleration and deceleration of the weft carrier. It operates independently of the rest of the loom, and consumes very little power.
Patent FR-2520864-A1 (FR)
Inventor: RODDE CHRISTIAN
IPC: G01F15/02
Filed: 1982-02-03
Abstract: A flowmeter has a tank disposed between a discharge circuit and a supply circuit from which the tank is refilled when the level of the liquid in the tank falls below a predetermined level. A plunger is suspended in the tank by a force sensor. The output of the force sensor is used to measure the rate of flow from the tank to the discharge circuit except when the tank is being refilled. Flow from the tank during a refilling cycle is approximately measured in response to flow parameters in the discharge circuit which are independent of the force sensor and liquid level in the tank. The flow parameters in the discharge circuit are monitored and calibrated during each tank discharge cycle, and the new calibration values are used during the next tank refilling cycle, to obtain reasonably accurate continued flow measurement during each tank refilling cycle.

Title: Cpd metallic layer formed on ceramic substrate - capable of being easily soldered to components
Inventor: PRIBAT DIDIER
IPC: H05K3/24
Filed: 1982-04-16
Abstract: A cpd. metallic layer which can be soldered on its free surface to an attached component is formed on a ceramic substrate as follows. A first adhesive layer (1) is screen printed onto the substrate (2) using a paste which contains a powdered metal, an oxide adhesive agent pref. glass powder or a metallic oxide and an organic binder and is then heated to between 800 and 1000 deg.C. Onto this first layer is screen printed a second solderable layer (8) using a paste containing metal powder and an organic binder, the metal being either the same or different from that of the first layer. This is again heated to between 800 and 1000 deg.C. Adhesion between the substrate (2) and the first layer (1) is a chemical oxide-oxide liaison at the interface and between the first layer (1) and oxide free second layer (8) is a metal-metal liaison at the interface. Used in electric circuits in particular multilayer circuits of a piled insulator/conductor/insulator structure in which the upper layer receives components or microunits. The metallic layer on the free surface of the substrate enables connections to be made easily.
