Patent FR-2269831-A1 (FR)
Title: Call simulator for communications exchange testing - has circuits with facilities for listening and dialling tests
IPC: H04M3/32
Filed: 1974-04-30
Abstract: Semiconductor circuits comprising the call generator are housed in a case with operating controls on the front panel. Jack sockets enable connections to be made to calling and called circuits. Other sockets permit connections to an amplifier and loudspeaker for listening tests. Manual selector switches connected to counter circuits permit the setting up of numbers for dialling tests. The number of figures transmitted is selected by a number selector switch which blocks additional numbers in automatic sequences. Operating sequences such as permanent cycling may be chosen using a sequence selector switch.

Title: Geothermal water heating system - using successive refrigeration circuits to heat water supply
IPC: F24D11/02
Filed: 1974-12-10
Abstract: A geothermal hot water system using two heat pumps, has a circuit using hot water arriving at 70 deg.C, with an evaporator, (3) a compressor (8), and a condenser (10) so that a water supply (27) arriving at 60 deg. is heated to 75 deg.C. The natural hot water, cooled to 37 deg., passes through a similar heat pump (14, 19, 21) so as to heat up the water supply to 60 deg. before the latter reaches the first heat pump, the natural water being cooled down to 5 deg.C. In alternative designs, instead of having two compressors (8, 9) driven by one motor (26), the system can be simplified by mounting the two compressor stages or a common motor driven shaft inside the same housing. Further, the two evaporators (4, 15) can be housed inside a common casing, separated by a divider plate. Further circuit designs are possible.

The shaft (23) carries a lever (16) connected to a second linear actuator (A). The combined action of both actuators (A, 40) alters the nozzle from a parallel shape to a convergent-divergent shape to suit the aircraft flying conditions.

Title: Sensor for self levelling headlamps - has sealed pivot bearing for sensing arm to prevent ingress of dirt and water
IPC: B60Q1/105
Filed: 1975-03-11
Abstract: The position of the axle is sensed by a lever whose other end operates on a spring loaded servo piston to alter the inclination of the headlights. The lever is provided with a bearing plate on each side of its pivot point, with the plates moulded on the lever. The plates locate in elastic lips around the entrance slot to the servo cylinder with additional sealing provided by an O-ring in the grooves between the lips. The lever bearing is secured by a transverse bar moulded to the plate and moving in a slot in the sides of the housing. A simple sealed pivot is thus provided for the sensing lever to prevent ingress of dirt and water.

Title: Heat developable photographic prod - contg leuco base of a dye, silver salt oxidising agent and reducing agent and binder
IPC: G03C1/498
Filed: 1975-07-25
Abstract: A heat developable photographic product in colour comprises a support bearing a layer contg. a photographic silver salt, a silver salt oxidising agent and a reducing agent, a polymeric binder, and also contg. a leuco base of a dye which can be oxidised to form a coloured image. The process comprises heating the exposed product at 80-250 degrees C for 0.5 to 60 secs. Previous products have employed colour couplers/oxidised developers to form the colour which requires a high pH and also p-phenylene-diamine developers can give rise to reduction of the silver salt e.g. silver behenate. The above process avoids the use of colour couplers.

Title: Recovery of copper from sulphides - by heating in vacuum with alkali metal polysulphide and sepg copper from melt
IPC: C22B15/00
Filed: 1976-01-06
Abstract: Cu is recovered from sulphide ore by mixing and firing the ore under vacuum in the absence of H2O, CO2 and O2 with at least a stoichiometric amount of a non-saturated sulphide of Na or K at 210-360 degrees C thereby forming a melt of Cu, Cu oxides and more saturated sulphides of Na or K and separating Cu from the melt. The ore, which may also contain sulphides of Ag, Pb, Mo, Sb and A, is first roasted at 300 degrees C to remove CO2 and H2O. The ore is then heated with the polysulphide, the melt is cooled and leached with water. The leach solution is separated and a metal above Mo in EMF series is added to precipitate Mo, As and Sb present and the filtrate is evaporated to recover sulphide and S. The sulphide may be thermally decomposed to a non saturated sulphide and recycled. The non-saturated sulphide may be generated in situ by mixing NaOH/KOH and S with the ore.

Patent FR-2344068-A1 (FR)
Title: Temp. regulation system for enclosure - uses correction for humidity in enclosure and operates with heat supply probes
IPC: G05D23/24
Filed: 1976-02-26
Abstract: The temp. regulation method involves the use of detectors which deliver a linear signal proportional to the thermal flux. These detectors have an identical very low dynamic impedance. Heat loss detectors are used to measure the thermal flux passing through the walls of the enclosure. They also measure the thermal flux given up by the thermal capacity of the enclosure. They also determine a connection factor for the degree of humidity in the enclosure. Heat supply probes are used to measure the flux from the heat supply source. The sum of the heat loss signals and the heat supplied signals are carried out separately. The relative influent sum, with sums of loss signals and sums of heat input signals is carried out separately with these partial sums.

Title: Card filing cabinet with retrieval system - has twisted bars which are rotated by push buttons to form drop slots for cards
IPC: B42F17/34
Filed: 1977-02-18
