Title: Ultrasonic lap butt welding of two metal strips - using sonotrode imparting vibrations to roller driven transversely across lap butt joint formed by two strip ends
Inventor: BESSON DANIEL
IPC: B23K20/10
Filed: 1980-04-16
Abstract: Continuous metal strip is made by welding a tail end of one strip to the front of the next strip. The overlapping ends of the two strips are placed on a welding table and held by clamps. The table is next lifted so the overlapping strip ends are forced at a predetermined pressure against a roller fixed to a sonotrode which is also provided with a photoelectric cell. The roller is moved across the joint, and the cell detects both edges of the overlapping strips and switches the sonotrode on and then off. The sonotrode subjects the roller to ultrasonic vibration to make the weld. Used in joining thin strips made of Al; Cu; or steel; but esp. Al strip coated with polyethylene and used in mfg. electric cables. The polyethylene is removed from the strip ends before welding and the continuous strip can be used in mfg. long cables.

Title: Battery electrolyte level monitor - includes two floats connected to magnetic cores in resonant coils to provide signals indicating electrolyte level and density
Inventor: PLESSIS ROBERT
IPC: H01M10/48
Filed: 1980-06-13
Abstract: The monitor includes two floats, one to detect the level of electrolyte, and one to determine the specific gravity of the liquid. The first float is made of material considerably less dense than that of the liquid and is a short cylinder (5). It is connected to a magnetic core (7) which moves axially in a coil (3) connected to a resonant circuit (4). This detects the electrolyte level. The second float is a longer cylinder (14) made of a material of density close to, but slightly less than that of the liquid. This float is similarly connected to a core moving in a coil (3') linked to a resonant circuit (4'). This circuit provides a signal which may be used to determine the specific gravity of the liquid (N). Both signals are fed via frequency-voltage converters (20,20') to a control circuit (21).

Title: Optical investigation of surface reflective properties - measuring included angle of light beam reflected from painted or bare metal panel to assess finish
Inventor: CRAHAY JEAN
IPC: G01B11/30
Filed: 1980-09-25
Abstract: The optical properties of a material such as sheet metal, which may or may not have been painted, are determined by aiming a low power light source such as a laser at the surface at an oblique angle. The included angle of the reflected cone of light represents the reflective properties of the surface. The process may be used in the automobile industry to determine the quality of painted or bare metal panels. The reflected cone of light impinges on a screen, where it may be measured manually or automatically. The area of the spot of light corresponds to the proportion of incident light which was reflected by the surface, and thus indicates the reflective properties of the surface. A television camera coupled to an image analyser may be used to detect the reflected light, and fibre-optic cables may be used to deliver the light beam to inaccessible surfaces.

Title: Water vapour condenser for steam turbine - uses refrigerating fluid to remove heat from water vapour to cause condensation
Inventor: TONDEUR GERARD
IPC: F01K23/04
Filed: 1981-03-13
Abstract: The process for condensation of water vapour forms part of the operating cycle of an electrical generator using the expansion of water vapour through turbines. Condensation of the water (1) is achieved by vaporisation of a refrigerating fluid. The temp. of vaporisation of this fluid under atmospheric pressure is less than that of water. The vaporised refrigerating fluid is expanded in a turbine (20), and subsequently condensed by heat exchange with the cold water in the course of being reheated. The liquefied refrigerating fluid is recompressed (29) and then carried back around in order to exchange heat with the water vapour which is to be condensed. The refrigerating fluid may be ammonia. The water vapour to be condensed is at a pressure of 400-500 millibars prior to condensation.

IPC: B62D29/00
Filed: 1981-03-23
Abstract: The fibre reinforced car body panel has a thin outer skin of metal to take the enamel finish and polish to resemble proper metal panels at a lower weight. The metal skin is pressed at low cost and with simple presses and the fibre moulded to the metal. The low weight, low cost panels are coated with a carbon based fibre layer on the inside for added protection, with the bulk being glass fibre based. The metal outer coating is no thicker than one mm and is painted using conventional techniques. The panel has the high gloss finish of metal panels, which does not dull as does a fibre panel.

Title: Automatic light control for vehicle - uses frequency-to-voltage converter and RC delay circuits to change parking lights to headlights in response to increase in engine speed
IPC: B60Q1/14
Filed: 1981-03-24
Abstract: The vehicle light control system is intended to change automatically from parking lights to headlights when the vehicle moves faster than a certain speed. This speed is detected by a frequency-to-voltage convertor which is attached to the alternator of the engine. The output voltage is compared with a fixed value in order to determine whether or not the speed exceeds a certain threshold. If the speed falls below the threshold, after the headlights have been automatically turned on, an RC circuit delays the reversion to parking lights. The system saves fuel, since power consumption is reduced, and also reduces stress on the driver since the lights are not on unnecessarily.

Title: Measuring system for passband of communications optical-fibre - has signal sequence generator with output converted to optical signal supplying photodetectors feeding comparator fed with reference
Inventor: PREVOT JULIEN
IPC: H04B10/07
Filed: 1981-08-25
Abstract: A photodiode receives the output from an optical fibre link. The signal is applied to a low noise preamp to drive a filter network where only one filter is selected to transmit a signal free from perturbations. A summer controls a gain controlled amplifier to amplify the fundamental frequency and avoid the parasitic frequencies. A processing circuit receives the filter output voltage and provides a display with the transmission frequency. The processing circuit controls a local oscillator driving a mixer for the input signal. A discriminator provides automatic frequency control for the local oscillator. The mixer output is filtered and demodulated and applied to a log. amplifier (64) to provide an attenuation display scaled in dB's, when the amplifier output is compared with a reference level.

Title: Washing suspended joints of meat - using brief hot and cold water jets to cleanse the surface of dirt and bacteria
Inventor: BEAU JEAN-CLAUDE
IPC: A22B5/08
Filed: 1981-12-29
Abstract: Meat in the form of quartered carcasses of boned joints are passed as pendant joints on a conveyor through an enclosure isolated by air jet curtains and within which the joints are subjected first to hot wash nozzles and then briefly to cold sprays before emerging dry after passing through the exit air curtain. Pref. the hot wash is by water jets operating at 4-40 bar pressure and 65-100 deg.C applied for 2-60 seconds. The rinse is of water jets at 2-25 bar and 2-16 deg.C applied for 4-25 seconds. As the joints pass through they are reoriented so that the jets impinge on all surfaces but also so that no pockets of trapped water remain to contaminate and spoil the meat. The enclosure is pref. built with smooth surfaces of stainless steel. Drainings are collected by a gutter. Used for cleaning meat prior to valuation and/or refrigeration under conditions which substantially reduce the concentration of superficial bacteria by a factor of at least 10.
