Title: Voltage converter for supplying accident blinker light - has comparators driving two-transistor chopper feeding tube via transformer and rectifier
IPC: H05B41/32
Filed: 1975-03-20
Abstract: The voltage converter supplies a blinker discharge tube used as a warning light at the scene e.g. a car accident. The lamp is connected across the output of a rectifier (P). The rectifier is supplied from the secondary winding of a transformer whose primary is coupled to a two-transistor chopper. The transistors in the chopper are driven by the outputs of two comparators and supplied from the battery. Each comparator compares a pilot oscillator output with the output of a circuit that corrects the symmetry of an error signal. the error signal is derived, by amplification, from the voltage across a resistor in one dc supply line.
Patent FR-2265950-A1 (FR)
Title: Locking mechanism with adjustable key - has sliding bolt within casing with two sets of locking shims operated by multi-pin push-key
IPC: E05B29/00
Filed: 1975-03-28
Abstract: The casing, as well as the sliding bolt have cavities in which a number of shims of different heights are arranged on their edges. The shims in the casing protrude into the cavity of the bolt as long as the key is not pushed into the keyhole and prevent the spring loaded sliding bolt from moving. The multi-pin latch key has pins of different lengths with chamfered ends. When the key is pushed into the lock, the chamfered ends lift the shims by amounts corresponding to their various heights. The combination of the pins with different length is such, that each shim is lifted by such amount that the top edges move into level and push upwards the set of shims in the casing, which, in turn clear the edge of the sliding bolt edge, hereby allowing the bolt to move.
Patent FR-2307316-A1 (FR)
Title: Magnetic sorting of perforated cards - involves series of pins perfectly parallel in vertical plane and friction between them in reduced to minimum
IPC: G06K21/02
Filed: 1975-04-07
Abstract: The magnetic perforated card (2) sorter has fins (7) which receive data according to perforation codes. It also has a device, which selects the fins as a function of the codes, by means of a selective magnetic system. Selection taking place for whatever height, surface and perforation zone the fins are acting at. The fins (7) have means which permits them to be maintained perfectly parallel to each other in the vertical plane, when they are placed in a container a group of them arranged without any pressure between them. This means permits simultaneous reduction of the surface contact existing between two neighbouring fins. It is associated with a means which suppresses the effect of a rotation couple which the fins are subjected to when the selection operation takes place.

Title: Temperature transducer - depending on magnetic core temperature characteristics, uses two cores in a bridge network activated by a transformer (NL150676)
IPC: G01K7/38
Filed: 1975-12-15
Abstract: The accurate temperature transducer appts. depends on the temperature characteristics of two magnetic cores. The device consists of two wound magnetic cores (10, 12) of not necessarily a square hysteresis characteristic, which are connected as two adjacent arms of a bridge network. The network is activated by a transformer of which the secondary winding constitutes the other two arms of the bridge. A variable tapping (25) allows a bridge balance point to be set over a curtain temperature range, the balance point being detected by a pull detector (32). A small output is thus produced for a particular temperature, whilst a larger signal of appropriate phase is produced above and below that temperature.

Title: IC engine electronic ignition advance system - is controlled by two pulse trains and reference pulse train which is independent of engine speed
IPC: F02P5/02
Filed: 1976-07-13
Abstract: The first pulse train frequency is independent from engine speed, while the second and reference pulse train frequencies are proportional to the engine speed. The pulses of the first pulse train are counted during the interval between two reference pulses. The pulse number so counted is coded in accordance with a specified ignition advance function. Starting with a reference pulse, the pulses of the second pulse train are counted between two reference pulses, and the number so obtained is compared with the coded number of the first pulse train. A control pulse is delivered when the two numbers are equal.

Title: Track for use with model electric railway - has lengths joined together using metal clips around each rail and tongues locating in cavities
IPC: A63H19/30
Filed: 1976-07-29
Abstract: The track is produced in lengths and joined together to form a continuous electrical circuit for a model railway. Each length consists of a base (24), moulded from plastic to portray the ballast and sleepers. Each rail is metal, attached (12) to the base. The lengths are joined using clips (16), one being fixed to each rail. These clips have spring sides to provide good electrical contact when pushed over the mating rail. At the same time, a tongue on the base, underneath each clip, locks into a cavity on the opposite rail. This provides the necessary mechanical strength for the joint.
Patent FR-2363514-A1 (FR)
Title: Automatic generation of hydrogen and steam - by reacting (ferro)silicon with caustic soda solution and using product pressure to regulate the quantity produced
IPC: C01B3/00
Filed: 1976-09-07
Abstract: Hydrogen and steam are produced in a water-tight tank that contains a caustic soda solution. Inside the tank is an auxillary vessel with permeable walls contg. the ferrosilicon or Si. This auxillary vessel sits on a piston rod allowing it to be raised above the level of the caustic soda solution. The gases pass to a collecting tank where the steam is condensed by bubbling the gases through water. A pipe, leading to a cylinder containing a piston compensated by a release spring that limits the piston travel, is taken from the water space of the collecting vessel. As the hydrogen press. rises the spring is compressed and the rod on the piston turns a multi-way cock to put the water under press. in the collecting tank, in direct contact with the piston in the generation tank. The rod of this piston rises, raising the vessel containing the ferrosilicon out of the solution. Used for generation of hydrogen and steam for industrial and domestic motors that are stationary or moving. Generates large amounts of products cheaply.

Title: Vertical concrete wall coffering panel stabilising system - has counterweight on arm erected by cable ready to raise panel from ground
Inventor: BACHER MAURICE
IPC: E04G19/00
Filed: 1976-11-08
Abstract: A coffering panel for vertical concrete walls with a conventional support framework attached to its rear, adjusted by cylinders at ground level, has an arm extending from the base, also at the rear, with a counter weight attached. This arm is attached by a hinge pin, so that when the panel is horizontal, ready to be erected, the arm is also horizontal. A lifting cable is then attached to the counterweight on the end of the arm, so that the counterweight is swung up on the end of the arm, until the arm is at right angles to the panel. In this position the arm is automatically locked by a swinging hooked lever. The panel can now be raised, assisted by the counterweight. This also opposes the force of the wind against the panel.
