Title: Time sharing multiplex telecommunications system - has relief line in ring brought into service in opposite direction
Inventor: PANDO BERNARD
IPC: H04M9/02
Filed: 1973-12-26
Abstract: The transmission path for the relief line is the reverse of that of the normal service line and is automatically brought into use. A normal service line (1) and a relief line (2) permit transmissions in opposite directions between subscribers equipments (11) which are connected to secondary changeover units (3, 5, 7, 9) containing switching networks (13, 15, 17, 19). The switching networks are controlled by control circuits (20) contained in each subscribers equipment. A principal unit (39) contains a connecting unit (27) and a changeover control circuit (41) which contains switching code (43) and address code generators (45). The address codes are detected (47) and the changeover control circuit activated on receipt of fault signals at a detector (49). This activates the subscriber's control circuit.

Title: Constant altitude maintaining aircraft control system - numerical computer memorises a number corresponding to required altitude
IPC: G05D1/04
Filed: 1974-05-13
Abstract: Aircraft altitude control system has a circuit with an altitude transductor (10) which generates an analogue signal corresponding to aircraft altitude, a clock impulse source (11), a numerical counter (12), a numerical analogue coverter (13), connected to the counter (12), which produces an analogue output signal corresponding to the counting recorded by the counter (12); a device which conditions the counter (12) so that it counts the clock pulses until the output signal reaches the altitude signal level at a wanted instant and memorises afterwards the number so that the output signal remains at a reference level practically equal to the signal altitude level at the wanted instant. A device compares the altitude signal with the output signal, and produces a correction signal in case of a difference between th altitude signal and the reference signal. The counter is a multistage binary device, and the numerical analogue converter is a resistance ladder network.

Title: Variable speed moving pavement - interlocking elements, spacing varied by pivoting levers running in helical drive slot
IPC: B66B21/12
Filed: 1974-06-27
Abstract: A variable speed moving pavement or conveyor, of the type where passengers step on and off slow moving sections and move faster between these sections, consists of elements, having interlocking strips the speed of the conveyor being determined by the separation of the elements. Beneath the conveyor surface a drive rod with a helical groove rotates, the pitch of the helix determining the spacing and speed. The spacing is controlled by levers (11) which have a protrusion (13) which runs in the helical groove, varying the inclination of the lever according to the pitch. The ends of the levers (12) engage in slots in the elements. Varying the lever inclination thus varies the element spacing.

Title: Steam heated calorifier - having elements with change from circular to rectangular to improve heat transfer from condensate
IPC: F28D7/02
Filed: 1974-09-06
Abstract: Calorifier for steam heating hot water for space heating purpose has elements enclosed in a vessel or container. The elements consist of a spiral of circular pipe which change into rectangular suction further down. This is so as to improve the ratio of surface area to cross section in the lower portion because here the steam has fully condensed and is condensate of lower volume and poorer hot-transfer coefficient. The diameter of the rectangular spiral is smaller than that of the circular spiral. The lower portion can also have elliptical cross section.

Title: Flat steel parts made by cold forging - using annealed blanks and tools providing close dimensional tolerances
IPC: B21K1/76
Filed: 1976-02-05
Abstract: Flat precision parts are made by cold forging, starting from a blank made by cutting or stamping. The blank has a wt. equal to that of the finished part, and is annealed to remove all internal stress; it is then cold forged between a punch and die, each consisting of several parts. When the blank is made from mild steel sheet, the latter is pref. given a spheroidising anneal to prevent cracking during forging. A blank is then stamped out of the sheet using a relatively large clearance between the blanking punch and die to avoid tearing or deformation at the blanked edges. The blank may also be annealed before forging. For cold forging, the pref. punch is provided with one or more outer concentric ring punches entering a die contg. one or more die rings forming the lower surface of the forged piece. The tools pref. include channels for removing phosphate or grease. Used esp. for mfg. parts with complex profiles from steel or alloy steels, to obtain close dimensional tolerances, defect-free forgings, and long tool life.

The hysteresis coupling (10) has a polarised rotor (11) which is rigidly fixed to the shaft (12) of the take-up spool and cooperates with a hysteresis band, with the housing of the hysteresis coupling (10).
Patent FR-2325003-A1 (FR)
IPC: G05D23/24
Filed: 1976-09-15
Abstract: The aim is to make a solar energy installation which makes possible more efficient utilisation of the heat obtained from solar radiation. To this end, the installation comprises a secondary circuit for the fluid to be heated. The secondary circuit comprises storage tanks (B1, B2, B3), each of which is provided with a heating coil. The installation also comprises a primary circuit which includes solar collectors (CS1, CS2, CS3) and the coils (S1, S2, S3), connected in parallel with one another and in series in relation to the solar collectors. In each of the tanks (B1, B2), with the exception of the tank (B3) situated further upstream in the direction of the circulation of the fluid to be heated in the secondary circuit, first detectors (RM1, RM2) of the temperature of the fluid to be heated are situated. Second detectors (RD1a-RD1b, RD2a-RD2b, RD3a-RD3b) detect the difference between the temperature of the transfer liquid in the collectors and the temperature of the fluid to be heated in the tanks. Associated with each coil (S1, S2, S3) are electrovalves (EV1, EV2, EV3) controlled by electric circuits (AE1, AE2) which are sensitive to the first and the second detectors to ensure initially the circulation of the heat transfer liquid in the single coil (S1) situated further downstream and then switch this circulation over in succession into the coils (S2) and (S3). The installation is envisaged for use for producing hot water.
