Patent FR-2248820-A1 (FR)
Title: Complete artificial joint between bones - has interlocked rings permanently attached together
IPC: A61F2/30
Filed: 1973-10-29
Abstract: The joint comprises two parts for rigid implantation in the bones involved between which relative movement must take place. There is a permanent articulated joint (10, 19) between the parts, typically in the form of two toroidal rings engaging together, one of which can be movably mounted in one of the parts. Typically this can be achieved by a trunnion rotating in a housing, but which can not slide in it. Where the joint is used for the shoulder, the part of insertion in the humerous can have a rod integral with one of the rings and with a hook end. It is implanted obliquely so that the hook engages through an external perforation in the bone.

Title: Peak detector of variable amp. signals with differencer and memory - has time marker activated by peaks exceeding level operated for given period
IPC: G01R19/04
Filed: 1973-11-09
Abstract: A system for detecting a row of signal peaks of varying amplitudes. The signals appear at the input of a differencer circuit (27) which has an analogue memory element (2) for storing the values representing a fraction of the amplitude of the last signal peak to appear acting as a reference threshold. The system contains a timing element (4) whose output is connected to the input of the reduction circuit control (3). The timing element is actuated for a given period when the threshold is exceeded. This actuation period is independent of the time interval between two peaks. The reduction element is translated into a fraction of the last peak to arrive.

Title: Double pump unit for central heating - blocks return flow when one pump of two parallel pumps stops
IPC: F04D13/14
Filed: 1974-01-23
Abstract: A pump unit for a central heating installation has two pumps (3) in parallel, which can be operated independently, mounted on a casing (1) between them so that water can enter through a common inlet (2), branch to either side to either pump, and so that the combined flows can unite in a common collector chamber (5) between them for delivery through a common outlet. At the entry ports (22) into the collector chamber is a spring loaded flap (31) which closes when its pump is not operating, thus acting as a stop valve which is self operating when a pump stops. A by-pass (36) with an externally operated control (37) communicates between th inlet port and the collector chamber.

Abstract: 1455593 Working up nitration mixtures BASF AG 4 April 1974 [6 April 1973] 14918/74 Heading C2C The invention comprises a process for working up a reaction mixture obtained by nitration of an aliphatic or cycloaliphatic ketone, in the presence or absence of the corresponding alcohol, with at least 95% w./w. nitric acid in the presence of an inert organic solvent for the organic compounds, wherein there is added to the reaction mixture a nitric acid of a concentration such that the reaction mixture contains 40 to 80% w./w. nitric acid prior to the separation of the organic phase. The nitric acid to be added to the reaction mixture following nitration generally has a strength of from 40 to 70% w./w. Working up is advantageously carried out at a temperature of less than 50‹ C. Magnesium nitrate may be added to the reaction mixture following nitration in order to diminish further the residual concentration of organic material in the aqueous nitric acid phase. Example 2 also describes the preparation of #-nitro capronamide by passing ammonia through 2-nitrocyclohexanone.

Abstract: 1512681 Multi-band aerial system THOMSONCSF 8 Aug 1975 [9 Aug 1974] 33249/75 Heading H4A [Also in Division H1] A multi-band aerial system comprises an e-m wave filter grid of substantially uniformly spaced metal elements on a dielectric substrate, the grid being transmissive to a first frequency band and reflective to a second, higher frequency band. First and second primary feeds direct first and second beams, respectively in the two frequency bands, onto respective opposed faces of the grid such that on leaving the grid the two beams merge into a resultant beam, outside the path of which the second primary feed is located. Fig. 4 shows a Cassegrain system of mirrors 80, 81, scanning in azimuth and elevation, onto which the resultant beam is directed by mirror 82. Grid 86 reflects the higher frequency band, fed from source S2 via mirrors 88, 87, and passes the lower frequency band, fed from source S1 via mirrors 85, 84, 83. In the Fig. 7 embodiment the filter grid 31 in horn 30 combines the beams from a dual-band high frequency (11 and 14 GHz bands) multiplexer-demultiplexer 33 with the beams from a dual-band low frequency (4 and 6 GHz) multiplexer-demultiplexer 32. An embodiment using a plane filter grid and plane mirrors instead of the curved grid 86 and curved mirrors 83, 84, 87 is described (Fig. 5, not shown). In other embodiments the filter grid forms a curved wall of a horn (Fig. 2, not shown) or is used to direct the resultant beam upward to a mast-supported mirror which is angled to direct the resultant beam horizontally (Fig. 3, not shown).

Title: Addressing circuit for integrated logic matrix - allows high speed switching with minimum power drain
Inventor: JOURNEAU JACQUES
IPC: G11C11/415
Filed: 1975-09-03
Abstract: The addressing circuit is for integrated logic units where the individual memory cells are arranged in a matrix, and is provided with read and write control lines. The design is intended to minimise the power required to provide ahigh switching speed. Switching is by two voltage levels via emitter followers in earthed collector configuration, each emitter being connected to an input point in the control system. Each emitter follower load resistor is connected to a common line fed from the supply across a current generator. The voltage swing between the potential at the emitter resistance line and the holding voltage is a quarter of that initiating the switching operation.

Title: Fuel injector pump delivery valve - relieves pressure after delivery to assist injector valve return
IPC: F02M59/46
Filed: 1975-11-28
Abstract: The delivery valve is fitted between the injector pump outlet and the injector valves and consists of a bore (16) whose one end forms a stop (17) for a hollow cylindrical unit (19) and joins the pump chamber. Between the ends of the bore an outlet (18) leads to the distributor part of the pump. The hollow unit has ribs (20) extending along its outer periphery which contact the bore inner wall and form a fuel channel. The hollow unit is pressed against the stop (17) by a spring (21) coiled around a conical abutment (23) which passes into the hollow unit. A piston (24) fitted inside the hollow unit, uncovers a bore (25) in the side of the hollow unit, when subjected to pressure from the pump chamber, allowing fuel to pass via the ribs (20) to the distributor outlet (18). After delivery the spring (21) snaps the hollow cylinder (19) back against the stop (17) and pressure from the injector forces the piston (24) back to return some of the fuel to the pump chamber.
