Title: Digital logic controller for gas burner - uses digital logic circuits to monitor burner status and to enable or disable burner operation or ignition
Inventor: RIGOLLET DANIEL
IPC: F23N5/12
Filed: 1981-07-09
Abstract: At least a solenoid valve regulates the flow of combustible. A flame detector (7), an igniter (21), and a thermostat (22) are provided, the latter controlling an interrupter in the supply circuit. An electrical contactor (23) is mechanically actuated and associated with a tap placed upstream from the solenoid valve. An electromagnet (6) holds the contactor (23) and the tap (1) in the open position when energised. A logic circuit, connected between the thermostat (22) and the flame detector (7) on one side and the electromagnet (6) on the other, comprises logic gates (8,11,12) which drive a timer (24) controlling the electromagnet (6). The logic circuit checks for correct ignition conditions and detects abnormal operating conditions, removing the electromagnet supply to provide fail safe operation.

Title: Car lighting circuit with switches for town traffic - has resistor in series with filament and connected between switch and diode
Inventor: AURET YVAN
IPC: B60Q1/14
Filed: 1981-09-03
Abstract: The lighting circuit for a car includes side lights, dipped headlight filaments, and main beam lights. A selector switch directs current either to the main beam filaments or to the dipped light filaments via two contacts. A relay, whose coil is controlled by a switch, is able to operate a further switch allowing current to flow to the dipped light filaments via a resistor and diode. The coil is supplied through the filaments of the lamp when travelling in urban areas, the arrangement allows the intensity of the lights to be reduced, in order to avoid dazzling other drivers.

Title: Laminated plastics panels supported by peripheral springs or frames - to allow relief of dimensional stresses without facial constraints
Inventor: MORVAN ERIK
IPC: E04B9/30
Filed: 1982-04-30
Abstract: Wall or ceiling lining panels of laminated plastic sheet a few mm thick are supported either in tension by use of suitable peripheral clips mounted on a supporting framework or are supported in compression by opposing borders braced as a distance shorter than the corresponding dimension of the sheet, so that the sheet adopts a curved profile to bridge the gap. Allows the sheet dimensions to respond to variations of ambient temp. or humidity without being stressed by differential responses of other materials: avoids the effects of such stress on panels bonded directly to supporting structures with a common interfacial major face. Pref. tensioned supports involves use of coil or concave leaf spring profiles. Used for panels used as reflectors, the form of the curvature may be controlled by the shape of adjacent framework or hanger bars.

Title: Supersonic delta wing aircraft - contains trapezoidal opening in each wing to increase lift at subsonic speeds
IPC: B64C3/54
Filed: 1982-05-17
Abstract: The delta-wing aeroplane contains an opening in each wing which takes the shape of a triangle, trapezium or parallelogram. The section of wing situated in front of the opening itself forms a front wing, the trailing edge of which is formed by the front edge of the opening. The section of wing situated behind the opening forms a rear wing, the leading edge of which is formed by the rear edge of the opening. The arrangement allows supersonic aircraft to generate extra lift at subsonic speeds.
Patent FR-2527831-A1 (FR)
Inventor: COUEGNOUX GUY
IPC: H01H71/24
Filed: 1982-05-28
Abstract: The operating device contains an insulating tube (2), a coil (9) which surrounds the insulating tube (2), and a slotted tubular armature (13) which is fitted in the insulating tube (2) such that it can be displaced. The armature (13) supports a peg (16) for controlling the contact, whose condition is intended to depend on the intensity of the current flowing through the coil (9). The armature (13) is continuously pressed into its quiescent position by a spring (26). As soon as the response threshold in the coil (9) is exceeded, the magnetic force exerted on the armature (13) is sufficient to displace the armature (13) into its energised position, against the influence of the spring (26). The armature (13) and the peg (16) are produced from a single sheet-metal blank whose rectangular part (113) is bent in a round manner in order to form the side wall. The invention is used to simplify production.

Title: Jet cut-off device for a sanitary shower.
IPC: B05B15/00
Filed: 1982-11-30
Abstract: The device comprises a conduit 10 communicating, at one end, with a feed hose 11 and, at the other end, with a shower head 12. A valve 18, together with a valve seat 19, is provided in the conduit 10. The valve 18 is translationally integral with a piston 26 arranged in order to slide in a sleeve 27, the interior of which communicates with a space 29, located between a gripping handle 20 and a conduit 10, and filled with water. When the user grasps the handle 20 and presses it in his hand, pressurised water in the sleeve 27 pushes back the piston 26, which causes the separation of the valve 18 from its seat 19 and the water can flow towards the shower head 12. The invention permits substantial savings of water for sanitary use.

Title: Noise rejection system for Doppler radar
Inventor: CHALARD CLAUDE ALAIN
IPC: G01S13/52
Filed: 1983-04-28
Abstract: The Doppler radar comprises a correlator (COR), a Doppler filter (FD), an integrator - detector (INT), a threshold system (S) and a speed estimator (EV-LA). The device has a constant rate of false alarms (TFAC) and uses the speed (v-hj) and noise (b-hj) provided by the speed estimator (EV). The information is used to validate detected contacts, delayed by a buffer memory (MTR). If in a window of distance there is no noise detected, one estimates the average speed of the sync. noise and the dense region. If there is sync. noise, the measured speed is compared with the average speed of the sync. noise, but if not it is compared with the average speed of the dense region. If the speed is detected clearly above the noise then it is accepted, but if not the detected contact is annulled.

Filed: 1983-06-03
Abstract: In a planetarium, the floor together with the seats can be pivoted between the horizontal position for planetarium presentations and an oblique position for wide-angle projection during the presentation. In order that the seats and seat platforms always remain horizontal in an arrangement of this kind, a second axis of rotation for a framework is arranged perpendicularly below the axis of rotation for the floor, this framework being connected to the floor in the manner of a parallelogram by vertical struts. The seats and seat platforms are fixedly connected to these struts.
