Patent FR-2303164-A1 (FR)
Title: Fuel air mixture and exhaust feed back system - regulates injection dwell by crankshaft speed variations using phase comparator
IPC: F02D41/14
Filed: 1976-03-05
Abstract: The engine is fed the weakest possible air fuel mixture in order to reduce the toxic content of the exhaust emission and to reduce the fuel consumption. The mixture regulator system consists of gaining an impulse signal from the engine crankshaft speed variations and feeding to a phase comparator to form a phase locked loop circuit. Should positive acceleration variations occur, a contact breaker switch (6) leading to the integrated comparator (5) opens. The contact breaker is formed as a field effect transmitter whose input is connected to the outputs of the phase comparator responding to the positive and negative crankshaft speed variations.

Title: Type bead reinforcement hoops made from aromatic polyamide cords - for less weight and easier tyre fitting than metallic bead hoops
Inventor: MIRTAIN HENRI JEAN
IPC: B60C15/04
Filed: 1976-08-11
Abstract: Tyre bead reinforcement made by spiral lay-up on to a drum mandrel of a rubber sheet incorporating an array of aromatic polyamide (aramide, e.g. 'KEVLAR'-RTM) cords followed by circumferential cutting of the wound sheet to obtain narrower hoops for individual bead reinforcement. The drum can be contracted radially to facilitate removal of the bead hoops after the sheet supported by the drum has been sliced circumferentially. The drum is covered with silicone rubber or other material resistant to cutting. Bead hoops of equivalent strength to hoops made of metallic cord are approx. 1/6th of the wt. of the metallic cords. The toughness of the polaramide cords and the method of cutting result in negligible damage or wear to individual cords or knives respectively. The greater extensibility of the polyamide bead hoops facilitates fitting/removal of tyres to/from a wheel rim.

Title: Blocking the pores in granules - esp. for foundry moulding sands, using reactive binders or fillers
IPC: B22C1/02
Filed: 1976-09-15
Abstract: Treatment of porous granular prim. materials for prepn. of foundry sands comprises soaking and filling the pores in the grains with mineral or quick drying organic impregnants which form chemical bonds or solidify in the pores.

Other impregnants are an aq. soln. of dextrin, sulphite lye, pitch, asphalt, wax, plastics and resins. Method may be used for impregnating porous natural sands, ceramic materials, artificial sands and natural rocks for use as foundry sands after grinding and classification. The amt. of binder required to mould the grains into foundry moulds is reduced by up to two thirds.

Patent FR-2375046-A1 (FR)
Title: Elimination of water from printing ink - by passing thin film of ink through a high frequency electromagnetic field
IPC: B01D17/04
Filed: 1976-12-21
Abstract: Printing ink is pumped from an ink well to a nozzle. This nozzle sprays the ink in a thin film vertically downwards through a heating chamber. At the bottom of the chamber the ink is collected in a sump and pumped back to the well. A tube positioned perpendicularly to the thin film in the heating chamber emits a high frequency electro-magnetic field across the area through which the ink is sprayed. This field heats the ink by dielectric losses and the water in the ink evaporates. A fan removes the water vapour from the heating chamber. The chamber is lined with a material that absorbs the hyperfrequency radiation given off by the tube. Device is partic. useful on offset print machines, bit also for removing water from other cpds., e.g. alcohols. Water is eliminated without destroying the composition of the printing ink by parallel entraining of certain volatile constituents of the ink.

Title: Automatic control and sequencing of accumulator powered vehicle - uses electronic logic circuit to ensure power is applied via bus bars in safe conditions
IPC: H02H7/20
Filed: 1976-12-21
Abstract: For a vehicle powered by accumulators an automatic control and sequencing system ensures that the power is applied in conditions of safety. The system comprises several bus bars with a control circuit containing logic gates. The accumulators of a vehicle are connected through a start stop switch to a primary bus bar which excites an information transmitter. A principal bus bar supplies several motors for steering and traction. A secondary bus bar operated by a switch in series with the start stop switch activates several control circuits. A control and sequencing unit produces validation signals from several input signals to operate a control unit, for the motors.
Patent FR-2371826-A1 (FR)
IPC: G04F3/06
Filed: 1977-01-17
Abstract: In this electronic multi-range time-delay relay, the setting member, e.g. potentiometer, which serves to set the time in a stepless fashion is operated by means of a transparent rotary knob (1) which overlaps the major part of the relay front panel (4). The time scale (12), which preferably occupies the edge region of the rotary knob (1), can be provided on the rotary knob or on the front panel. A correspondingly smaller changeover knob (2) is present on the rotary knob (1) for the purpose of preselecting the timing ranges. The changeover knob (2) is mounted on a spindle which is guided through the rotary knob (1) and the setting member for setting the time in a stepless fashion. The spindle is part of a changeover switch by means of which different resistors, for example, for the individual timing ranges are switched into the circuit. By comparison with the conventional juxtaposition of stepless and range time setting, this superimposed arrangement of knobs and setting means facilitates optimum use of space for miniaturisation in conjunction with a simultaneously guaranteed accuracy of setting.

Title: Heat-storage material pref. based on hydrated salts - contg. nucleating agent, is suspended in colloidal suspension of thixotropic material
Inventor: CAPITANT MATHIEU
IPC: C09K5/06
Filed: 1977-06-29
Abstract: A medium for storage of heat is based on a compsn. that changes from the liq. to the solid state subject to undesirable sedimentation of a solid, particular fraction when the compsn. is at least at the temp. of change of state. The compsn. includes a nucleating agent and the medium is obtd. by suspending the compsn. in a colloidal suspension of a thixotropic material. The colloidal suspension is pref. stabilised by a peptising agent, pref. CMC with addn. of a wetting agent. The medium is used as a method of accumulating heat in an isothermal manner over the temp. range -30 degrees C to 180 degrees C esp. for storage of solar heat. The medium resists the degradation by sepn. into two phases that is a disadvantage of the use of polyhydrated salts for heat storage. This permits the medium to undergo several hundred storage- "destorage" cycles with only small loss of efficiency. The addn., the use of new nucleating agents increases the range of polyhydrated salts and hence widens the range of temps. of change of state that can be used.

Title: Bakery prod. pressure baked in extrusion cooker - using as main ingredient conventional bread which is dried and crushed
IPC: A23L1/18
Filed: 1977-11-16
Abstract: Bakery prod. is pred in a process of the type in which ingredients, e.g. flour, salt, water, are passed through an extrusion cooker in which they are subjected to high temp. and high pressure. A bread prod. which has been conventionally kneaded, fermented and baked is used as the main ingredient. This is first dried and/or toasted pref. to a moisture content below wt. 10%. The ingredient is then crushed ready for extrusion cooking. The bread prod. used as main ingredient can be freshly made, just before the drying stage, or it can comprise stale bread and mfg. waste for reworking. Other raw materials such as flour, salt, sugar and starch, can be mixed with the main ingredient just before cooking extrusion. Since the main ingredient has passed through a fermentation process, the final prod. has an acid pH similar to normal bred. The final prod. is an appetising, low calorie food with a distinct bread flavour and attractive, toasted appearance.
