Title: IC engine testing electronic diagnostic appts. - includes engine position and ignition sensors providing signals to determine speed and ignition advance angle
Inventor: MEULEMAN JEAN-JACQUES
IPC: G01M15/05
Filed: 1980-07-22
Abstract: The appts. is connected to an electronic ignition system which includes transducers measuring the piston positions in order to synchronise the ignition pulses applied to spark plugs. Two digital displays are provided, the latter's inputs being connected via a multiposition switch. A first decoding circuit provides a reference signal relating to the ignition timing, and a second circuit provides a square signal indicating the relative phase between the two input signals.

Title: Polycrystalline silicon mfr. from crystallised base material - by electron beam bombardment to produce local fusion and recrystallisation
Inventor: CASENAVE DANIEL CYRILLE
IPC: C30B13/00
Filed: 1980-07-18
Abstract: Polycrystalline Si is prepd. from a crystallised base material by (a) holding the base material by at least one of its edges in a vacuum chamber; (b) bombarding it with an electron beam, sweeping it in alternating fashion to provoke local fusion of material giving rise to subsequent crystallisation; (c) simultaneously provoking a relative displacement between the material and the beam in a direction crossing the direction of sweep. Used in photocells, esp. for conversion of solar energy. The material is prepared economically without excessive use of energy. The base material may be used at a level of purity which may even be as low as metallurgical purity.

Title: Doppler radar operated movement detector - has logic circuit analysing output to allow operation of automatic doors in response to selected movements only
Inventor: OTTO HANS-ULRICH
IPC: G01S13/56
Filed: 1980-10-28
Abstract: The movement detector comprises a radar signal source transmitting from a radar aerial, and two detectors (2,4) intended to receive this signal. The two detectors are positioned at different distances from the transmitting aerial to receive radar waves reflected by the target. By the Doppler effect the frequency received by the first detector is increased if the target is approaching and that received by the second target is decreased. The output signals of the two detectors are fed to a phase comparator (18). The phase comparator output and the output signal of the receiver are fed to a logic circuit (52) which detects movement in the required direction. The output is then used to control the operation of automatic doors. It is sensitive only to movement in the direction towards the doors and is not affected by people walking past, or, for example, by falling rain or snow.

Title: Hot air blowing hair brush - has push-on fitting to hair dryer and air flow both radially out from centre cylinder and transversely across bristle tips
Inventor: SCHWOB PIERRE
IPC: A45D20/52
Filed: 1980-11-13
Abstract: The hair brush has bristles or teeth protruding radially and distributed along the length and round the circumference of a cylindrical former. An enlarged fitting at one end allows connection to a blower type hair dryer which forces hot air along the length of the former to exit radially. The cylindrical former is mounted so it is free to rotate on a bolt running along its axis and fitting into a hole in a central boss in the mouth of the larger diameter push on fitting to a hair dryer outlet. Air from the dryer passes both over the oute surface to the bristles and inside the cylindrical former. The air passing inside the cylinder escapes radially through slots cut at the base of the bristles or teeth.

Title: Stabilised voltage reference integrated Zener diode - has pyrolytic silicon passivation covering over circuit removed from certain areas after masking
Inventor: BARTHEZ JEAN
IPC: H01L29/866
Filed: 1981-04-27
Abstract: The integrated circuit is formed on a substrate of silicon and includes at least one reference voltage zener diode. The zener diode has a high degree of stability, and consists of N-P junctions. The circuit is covered by a passive layer of pyrolytic silicon oxide or silicon nitride outside the contact plots, which receive soldered wires for external connections. The covering is also omitted in an area which covers each of the reverse biased N-P junctions which constitute the zener diode. After the stage in which the layer is deposited, a single stage of masking is used in order to define the areas which are not to be covered by the layer i.e. the contacts and the reverse biased junctions. The arrangement may be applied to circuits containing only zener diodes, or to more complex circuits of which the zener diode forms only a part.

Title: Solar heating enclosure for fermentation of compost etc. - to eliminate use of internal pipe work
Inventor: GERMON BERNARD
IPC: F24S20/30
Filed: 1981-06-05
Abstract: An enclosure for maturing compost etc. comprises a bell-shaped casing of metal painted black externally and with a reflective inner surface.

Simpler and more reliable than use of internal serpentine fluid heat transfer piping. Pref. the enclosure stands on a grid or mesh to allow ventilation from below through biomass within to a vent at the top of the enclosure. During cool weather or seasons, the heat input may be supplemented by introducing warmed air from below. A nitrogeneous soap may periodically be circulated from a sump beneath the enclosure to an overhead nozzle to keep the fermenting mass moist. Opt. the outer surface of the enclosure is protected by transparent coatings, opt. microblister film.

Title: Evaporator de-icing in air heat pump driven by heat engine - using engine cooling water and exhaust heat to melt external ice on evaporator tubes
Inventor: LEORAT FRANCOIS
IPC: F25B27/00
Filed: 1982-04-14
Abstract: The heat pump installation has a compressor unit (10) driven by a heat engine (16) to circulate a refrigerant (for example freon) through a condenser (12) and an evaporator (14). The evaporator has an internal network of pipes, in the vicinity of the refrigerant pipes, supplied (40,42) through a three-way valve in the cooling water system of the heat engine. The engine cooling water is held in a tank (30) and is normally circulated only through a cooling radiator (34). When de-icing is required some of the cooling water is diverted (32) to the evaporator chamber (14). A solenoid valve (28) is used to divert the refrigerant round the condenser (12) during the de-icing.
