Title: Electronic anti theft device for handbags - has siren sounded in absence of siren bypass bracelet
IPC: A45C13/24
Filed: 1975-05-09
Abstract: The anti-theft device consists of a detector which is placed in the handbag, document case or suitcase. When anybody approaches the bag this detector causes a siren to sound, but when the owner is carrying the bag the siren does not sound. This is because the owner wears a bracelet which broadcasts a signal which completes the circuit but bypasses the siren. The detector has two metal plates which complete the circuit when someone approaches them. The switches of the circuit are contained in the box of the detector so that the thief cannot stop the siren sounding.
Patent FR-2271966-A1 (FR)
Title: Pneumatic control valve for trailer brakes - which holds trailer pressure in direct relationship to towing unit pressure
IPC: B60T15/18
Filed: 1975-05-23
Abstract: The pneumatic brake system of the towing vehicle operates at a high pressure in order to reduce the size of air pressure reservoirs, and to increase the response of braking. The trailer brakes operate at lower pressures and are coupled to the towing unit brakes by a special valve which controls the ratio of pressures rather than the absolute pressure of the trailer brakes. During braking both towing unit and trailer pressures drop by proportionate amounts, while the valve maintains the pressure ratio. This prevents large amounts of air draining from the high pressure side to the low pressure side during successive braking, so that the towing unit brakes remain at their most effective level.

Patent FR-2337404-A1 (FR)
Inventor: GREGG GORDON E
IPC: H03M13/15
Filed: 1976-12-28
Abstract: Apparatus for directly decoding and correcting double-bit random errors per word and for detecting triple-bit errors per word is disclosed   Said apparatus comprises a syndrome calculator which operates upon codewords received from memory as generates syndromes   The  syndromes are operated upon and translated by a mapping device which generates pointers identifying the bits which are in error   The pointers are then passed through decoding means to generate error words which are summed with the received word from memory to provide a corrected codeword.  The syndrome calculator may further provide a parity check signal to determine if a three-bit error is present, in which case the  decoding means are not enabled and a signal is generated indicating that a triple-bit error has been detected which is not correctable. This invention includes circuitry for systematically multiplying two arbitrary field elements in a Galois field GF(2m). Each element is represented by an m-bit binary number.  The multiplicand field element is passed serially through a plurality of m-1 modulo multipliers.  The multiplicand and the product from each of the m-1 modulo multipliers are passed through networks which are gated by bits of the multiplier field element forming partial products.  The partial products are summed to form the bit representations of the final product.

Patent FR-2389000-A1 (FR)
Title: Burner fuel control for turbine - has servo device varying return flow in opposite sense to delivery flow to widen operating range
IPC: F02C7/22
Filed: 1977-04-29
Abstract: A turbine (1) is supplied with gas heated by a bank of burners (2). A variable speed pump (3) delivers fuel to the burners and a regulator (9) allows a controlled quantity of return to the fuel tank (6). The quantity burnt (Q1) is the difference between that delivered (QE) and that returned (QR). An electronic controller (4) with an input from a tachometer (5) on the turbine varies the speed of the fuel pump. A pressure controller (10) adjusts the return fuel regulator (9) so that the return quantity (QR) varies in the opposite sense to the delivered quantity (QE) as the pump speed changes. A small range of pump speeds thus produces a larger range of fuel input quantity (Qi). This enables a simple pump (3) to be used for a wide control range.
