Patent FR-2474764-A1 (FR)
Title: Semi-crystalline silicon photovoltaic cell - having large surface grains and junction extending into grains and along boundaries
Inventor: LINDMAYER JOSEPH
IPC: H01L31/0368
Filed: 1980-01-28
Abstract: The cell is formed in an Si wafer having a major surface adapted for impingement of light formed from randomly arranged, irregular, individual Si grains having mean dia. >=100 mu. (pref. >=1 mm) and grain boundaries that contact or are sepd. only slightly from adjacent grains at the impingement surface. A photovoltaic junction is formed extending across and below the surface and into the interior of the wafer along and inward of the grain boundaries, penetrating the wafer so that the total junction area exceeds the prod. of linear dimensions of the wafer surface but not so that the junction extends completely round the Si grain boundaries or to the opposite surface. The junction is formed by (a) diffusing impurity into the impingement surface and (b) maintaining in an atmos. free from the impurity at temp. and for a time causing the impurity to penetrate between grain boundaries and into individual grains. The cell gives satisfactory energy prodn., e.g. 15% conversion efficiency, at an efficiency/expense ratio much better than monocrystalline Si cells.

Title: Thief proof cylinder lock - has hard armoured screen in cylinder extending into radial core groove
IPC: E05B27/04
Filed: 1980-02-05
Abstract: The cylinder case in the lock contains pin springs prestressing pin tumblers to the key channel, to hold the core firmly against turning. The core (14) contains a radially opening groove (40) flush with a pin tumbler (18). The cylinder (10) has a protective screen made of material harder than the case (12) and fastened in the case. The screen (42) has walling between the cylinder core end and a case pin (50) allotted to the tumbler assembly. The screen extends outwards from the case into the groove (40). This affords better protection from attacks in the pin tumblers' plane and along the line between core and case.

Title: Sliding shutter mould for concrete kerb - has interior insert linings changing kerb section without changing mould
Inventor: MEDINGER JEAN-CLAUDE
IPC: E01C19/48
Filed: 1980-03-18
Abstract: The sliding shutter continuously casts kerbs with a backing or with an integral pitched channel by blanking off the flow of concrete using mould inserts. An insert on the left produces the kerb and channel, an insert on the right produces the kerb and backing. The mould is preceded by an integral hopper box and tapered walls in this aid mould insert removal. On a single pitch road where a channel is required only on the lower side, the mould after casting can be moved across the road to continue working in the opposite direction towards the starting point.

Title: Automatic graphic data generator for TV data - uses graphic pen having optical detector and data generator providing cartesian coordinates and microprocessor for information sequencing
Inventor: GOGUET ODILE
IPC: G06F3/0488
Filed: 1980-05-23
Abstract: The device uses a graphic table (1) and pen with an optical detector (2) and also a monitoring and composing keyboard (3).

The coordinate data is interrogated by validation (41) and address calculator (42) and applied to the image composing unit (43) in a composing assembly (4). This data then passes via a storage unit (5) to a video terminal (6). The keyboard is used to input commands such as display functions for a cursor, graphic characters, or semi-graphic characters. The latter comprise elementary rectangles which are chosen from a predetermined matrix.
Patent FR-2459438-A1 (FR)
IPC: F28D21/00
Filed: 1980-06-13
Abstract: In the heat exchanger (16), the heat of the heating-boiler waste gases is used for heating the return run water. The heat exchanger is characterized by a housing (17), inside which a number of pipe coils, through which the return run water can flow are arranged laid parallel to one another in the return run pipe (14) and preferably lie transversely to the smoke gas through-flow. The structure of the heat exchanger allows a compact construction and the subsequent installation or removal of a coil, so that it can easily be added and adapted to existing heating installations.

Title: Opto-galvanic analyser for small concentrations in gas samples - uses two facing mirrors in analysed gas cavity to obtain multiple reflections of beam
Inventor: BERTHOUD THIERRY
IPC: G01N27/62
Filed: 1981-08-13
Abstract: A gas to be analysed is injected into a tube (32) through an injector tube (36). The gas is carried through a high frequency generator assembly (30) to excite the gas. The carrier gas is inert and is supplied from a gas bottle (34). A plasma (38) is generated at the outlet of the gas supply tube which is located between two mirrors (M1,M2) facing each other and onto which a pulsed laser beam (26) is directed from a laser (24). The laser beam is subjected to multiple reflections by the mirrors. Adjacent to the plasma are electrodes (18) powered from a high voltage supply (20) to produce ionising currents in a load resistor. A measuring circuit (28) allows the current variations to be measured resulting from the photonic irradiation.

Title: Torque measuring system for twin engine aircraft - has counters for measuring durations of mark and space periods torque signal and with outputs fed to microprocessor
Inventor: SNOWDEN DAVID CHRISTOPHER
IPC: G01L3/10
Filed: 1981-08-26
Abstract: The torque measuring system comprises respective inductive sensors for each engine of a twin engine aircraft gas turbine engine installation. The sensors are positioned to co-operate with respective pairs of toothed wheels which are secured to axially spaced points on the engine shaft whose torque is to be measured and have interlaced teeth whose spacing varies with torque. Each sensor produces a torque signal which, after suitable pulse shaping has a mark-space ratio representative of torque. The respective durations of the mark and space periods of the signal are measured digitally by counting at counters clock pulses during successive groups of mark periods and space periods. The accumulated counts are then subjected to recursive digital filtering by a microprocessor in accordance with a predetermined function approximating the response of a low pass or, more specifically, a second order Butterworth filter said to increase resolution and enhance noise rejection. The microprocessor then calculates the torque for each engine, using the appropriate filtered counts together with digital signals respectively representative of the temp., stiffness and zero-torque twist of the respective shaft.

Title: Amplitude and phase comparator for target identification - has processor calculating modulus and argument from processed sampled signal data taken within wave period of signal
Inventor: GUERN RENE
IPC: G01S7/285
Filed: 1981-10-15
Abstract: Two sinusoidal signals of the same frequency from a coherent receiver are applied to A/D converters controlled by a synchronising circuit to produce sampled data. The sampled signals are memorised and processed to produce two pairs of values representing digital valves of instantaneous amplitude of the two complex signal components. These pairs of valves are applied to multipliers whose outputs are summed. The outputs of another pair of multipliers are subtracted and the outputs from one processing circuit are multiplied to obtain a sum of the squares signal from a summer. Two dividers determine the ratio of each of the summer outputs w.r.t. the squared sum valve. The real and imaginary components are used by a processor to determine the modulus and argument of the vector to give relative amplitude and phase shift. The system may be used in undersea surveying for petroleum layers.
