Patent FR-2247840-A1 (FR)
Title: Battery voltage monitor for stand-by battery connection - has resistance bridge across battery terminals controlling switching thyristor
IPC: H02J9/06
Filed: 1973-10-15
Abstract: The battery voltage monitor, for e.g. sonar buoys, has the main battery connected in series with a diode across a resistance bridge input diagonal. One resistor in the bridge is replaced by a diode. A transistor emitter/base junction is connected across the bridge output diagonalM and its collector is connected to the base of a switching transistor. The switching transistor emitter is coupled to a thyristor gate and turns the latter on when the battery voltage drops below a given level. The thyristor is connected in series with a switching device or similar, e.G. a resistor across the main battery. The switching device actuates the stand-by battery when the thyristor is turned on.

Title: Vacuum deposition of catalyst - from atomic dispersion produced by bombarding target with accelerated ions
IPC: B01D53/86
Filed: 1973-11-29
Abstract: A e.g. Pt catalyst, is deposited on an Alumina substrate; as an atomic dispersion, produced by bombarding a target with inert ions, e.g. Argon, accelerated, as produced by glow discharge between an anode and a Pt cathode. The target is orientated at 45 degrees To the ion beam, and the substrate is at right angles to the target. Equivalent activity is produced by a much lighter catalyst deposit, because agglomeration does not occur, as with vapour decomposition; and catalyst may be more selective, e.t. in producing higher proportions of butenes, in butane from butadiene hydrogenation. The substrate may be of known extended surface type, or may comprise e.g. alumina crystals, continuously reoriented by vibration, e.g. on the diaphragm of a loud-speaker.

Title: Synchronization of set of pressing-machines - has each machine operated by individual variable speed motor
IPC: B21D43/05
Filed: 1974-02-22
Abstract: Each machine in a set of several pressing-machines, linked together by conveying devices, is driven by separate variable speed drivers. Each part-carrying conveyor also has its driving mechanism separate from that of the press, as well as its own lifting and positioning parts and a step by step conveyor band. The speed of these individual driving units is synchronized with the pre-set value of one of them. For the part-carrying system variable speed motors, preferably direct current are used.

Title: Forming polycrystalline areas on substrate - using laser or electron beam preparing areas for epitaxial deposition
Inventor: LAUVRAY HUBERT
IPC: H01L21/20
Filed: 1974-09-03
Abstract: Localised layers of polycrystalline material are formed on a monocrystalline slab without the need for complex chemical processes and without disturbance of surfaces other than those under the polycrystalline layers. The area to carry this layer is subjected to a laser beam or an electron beam such as to disrupt the crystal lattice to a depth not greater than 1000 Angstroms. The beam is swept over the area in such a way that a mask is made unnecessary and the polycrystalline material is laid using an orthodox epitaxial technique. Using silicon, resistivities of the order of 106 OHM/CM may be achieved, reducing carrier lifetimes and capacity effects.

Title: Rotary wing producing lift and thrust - has horizontal blades with pitch control, rotating about horizontal shaft
IPC: B64C39/00
Filed: 1975-02-27
Abstract: A lift and thrust rotor for aircraft can be used in pairs mounted horizontally in the positions normall ied by the aircraft wings. Each consists of long thin blades (11, 12) parallel to and rotating around a horizontal drive shaft (18). Each blade is pivoted about a longitudinal axis (13) and a pitch mechanism comprising a toothed belt drive (32) actuated by a cam (38) ensures that its incidence is correctly maintained as the assembly rotates. The pitch mechanism can be adjusted during flight, so as to rotate the resultant aerodynamic force vector. There is reduced drag and the rotor is more efficient than a helicopter rotor because the baldes are at the same angle to the relative airstream along their entire length. An aircraft fitted with the rotor has short landing capability and also, because of low rotor speeds, low noise.

Title: Tube prodn. by winding resin impregnated textile onto mandrel - and using high frequency capacitative heating to cure resin
Inventor: ROELLINGER PHILIPPE
IPC: B29C53/60
Filed: 1975-03-07
Abstract: A short tube used e.g. as a textile bobbin is produced by winding a thermosetting resin impregnated textile onto a heated mandrel mounted on a rotating spindle. After a predetermined thickness of the textile has been wound onto the mandrel the textile is cut and the mandrel is removed from the spindle and heated by a high frequency capacitative heater to cure the resin. Finally the tube is removed from the mandrel and the ends of the tube are finished off whilst the mandrel is fed back to the spindle for re-use. The tubes are cheap to produce.
Patent FR-2267063-A1 (FR)
Title: Safety belt clasp with notched tongue and fastener - has two fastener plates forming tongue guide and containing pivot cock
IPC: A44B11/25
Filed: 1975-04-09
Abstract: A side notched tongue is accepted by a fastening component and two fastener plates form a guide for the tongue. They contain a pivot lock which acts with the indentation in the tongue. Two cut-outs in the fastener plates allow the lock to pivot about an axis normal to the plates, while it is forced into the tongue guide by spring force. There are fixed guide sections between the fastener plates acting with the tongue side faces and these give the tongue a guide direction coinciding with its longitudinal direction in the position in which it is locked in the clasp. The side of the pivot lock facing the tongue in its open position includes an expanding angle with the tongue longitudinal direction. The guide direction is inclined in that region in which the thicker section of the tongue passes by the lock and shortly before reaching the locking position it transfers into the direction coinciding with the tongue longitudinal direction.

Title: One-way rotary access gate - has ratchet mechanism controlling rotation and fixed bars on one side interleaved with gate bars
IPC: E06B11/08
Filed: 1975-06-10
Abstract: The rotary access gate allows passage in one direction only, being particularly for use at railway stations, fairgrounds, etc. A spring loaded ratchet mechanism allows rotation of the gate in one direction only. It can be divided into sectors by racks of bars extending horizontally (d) from the central column (a), passing between the bars of a fixed rack (e). The latter are at the same interval, but offset in the vertical direction for half an interval. Thus the fixed rack prevents passage past the gate on one side of the vertical column.

Title: Measuring unit for mutual surface slippage - has two pulse generators whose pulse repetition frequencies are proportional to the speeds of the objects
IPC: G01R23/02
Filed: 1975-12-30
Abstract: The mutual surface slippage measuring device is especially for detecting the movement between the driving hub and the brake surface of a motor vehicle wheel. It includes a comparator comparing the two pulse trains. Each pulse generator is connected to an allocated measuring device which deliver a test value proportional to the spacing of puses from the respective generator.
