Patent FR-2230957-A1 (FR)
Title: Revolver with sighting aid - beam of light directed onto target by torch type fitment
IPC: F41G1/35
Filed: 1973-05-24
Abstract: A revolver carries a compact cylindrical torch casing (3) secured by means of clips (4, 5) and aligned so that a beam of light is directed onto the target when the torch is switched on. The torch can be actuated by the trigger (14) by means of a switch (13) connected by wires (9, 10) passing upwards to the torch above, so that the target is illuminated momentarily. Thus only a pair of small batteries is required and the size of the torch is suitably reduced. The torch casing contains two miniature batteries behind an enclosed bulb. The front of the casing contains a lens which forms the objective of the torch, thus producing the required spot of light on the target. The revolver is first pointed in the general direction of a target and a small initial pressure applied to the trigger. This closes the switch and energises the bulb, thus allowing accurate aiming before firing the revolver.

Title: Statistical analysis of voltage fluctuations - direct numerical readout after comparison
IPC: G01R19/04
Filed: 1973-06-06
Abstract: An equipment designed to overcome the disadvantages of poor accuracy and lengthy interpretation of existing recording systems provides a direct numeric readout of voltage fluctuations which exceed a pre-determined amplitude and duration. The voltage is repeatedly compared with a series of pre-set amplitude thresholds typically 5%, 10%, 15% etc. below normal, to determine when a reduced amplitude exists and when it does so for more than a pre-determined time interval. The number of such occasions is counted and recorded.

Title: Vehicle air filter cartridge - with joints manufactured in a single moulding operation
IPC: B01D46/52
Filed: 1973-11-21
Abstract: Vehicle air filter cartridge comprises a cylindrical folded paper element, opt. reinforced with inner and outer perforated metal tubes, and top and/or bottom members made of fusible material, e.g. PVC, which form a strong bond with the element and reinforcements, and which may be reinforced with rigid metal discs. In assembling the filter, the whole structure is placed between two half-moulds, with rigid metal annular disc, pref. of Al or other electrically conductive material, on the outside of the top or bottom member. The disc is subjected to an alternating magnetic field to produce Foucault currents which raise its temp., thus softening the fusible material and swelling the jointing material; the latter is pushed towards the outside of the mould cavity, and the disc is pressed to form the bond between element and top or bottom member.

Title: Flushing toilet bowl with syphon system - has outlet opening connected to combined comminuting and syphoning device
IPC: E03D9/10
Filed: 1974-02-22
Abstract: The flushing toilet bowl is connected to a comminuting device which has an electric motor driven rotating paddle system.

Title: Impulse synchronised motor circuit - uses rotor pulses in combination with control pulses to set applied voltage
IPC: H02P23/00
Filed: 1975-11-26
Abstract: The dc motor has an impulse generator, typically a switch on its rotor which, in combination with a shaping circuit provides impulses to one input of a bistable switch. The other input is a similar pulse train from a controller. The pulses combine to form an output train whose pulse duration depends on the relative displacement of the two inputs. This output controls the mark-space ratio of the voltage setting circuit (3) and therefore the mean applied voltage of the motor thus controlling the speed. The application is typically to camera or projector drives where the motor speeds has to be synchronised with that of another camera or with external channels such as sound.

Title: Pulsed microwave field detector - has transistor with polarisation circuits at each terminal, tuned circuit in base and indicator circuit in collector
Inventor: VECCHIS MICHEL DE
IPC: G01R19/145
Filed: 1976-03-11
Abstract: A microwave field detector is used, the microwaves being modulated by pulses. It comprises a hypofrequency transistor whose three electrodes are each connected to a polarisation circuit. The base (14) is connected also to an integrated circuit tuned to a neighbouring frequency to that of the microwave field. The collector (15) is connected also to an indicator circuit whose time instant is high compared with the pulse repetition frequency. The base polarisation is fixed near the optimum value at which the transistor and the tuned base circuit presents the maximum selectivity at the frequency of the field. The collector polarisation is fixed in order to obtain an impedance which provides good coupling with the antenna, thus, at the minimum level of detector functioning, the power injected into the transistor produces a maximum excursion of the semicontinuous perentials of the transistor's electrodes.
