Patent FR-2477718-A1 (FR)
Title: Ultrasonic appts. for tube fault detection - utilises direct acoustic to optical conversion of output from transducer having shape of tube periphery
Inventor: DORY JACQUES
IPC: G01S15/89
Filed: 1980-03-07
Abstract: A number of ultrasonic transducers are arranged around the periphery of a tube in order to detect any faults which are then displayed by acoustic to optical conversion. The speed of operation is sufficient for production purposes. A generator produces a sawtooth waveform at a particular frequency to produce an acoustic pulse which drives a number of comparators. Potentiometers provide a reference potential and give a delay to the leading edge of the waveform. The waveform is shaped and applied via back to back diodes to transducers around the periphery of a tube. The diodes ensure that the returned echos pass to amplifiers which drive an acousto optic display for direct display of any faults.

Title: Electric cooker hot-plate - has spiral heating element and is sealed by stainless steel mounting ring against ingress of food particles
IPC: F24C15/10
Filed: 1980-05-16
Abstract: The electric hot plate consists of a cast iron griddle underneath which a heating element is mounted in a spiral groove. The heated section of the electric hot plate is bounded by an annular flange which has a cylindrical outer surface. The upper edge of the flange forms a cone which flares outwards. The hot-plate is supported by a mounting ring which prevents food particles which have dropped from cooking utensils from entering the appliance. The mounting ring is made from thin sheet stainless steel and has a conical outer surface which corresponds to the surface of the flange. It forms a tight fit to prevent the ingress of food particles. The peripheral edge of the mounting ring slopes gently towards the supporting surface.

Title: Thin component distribution feed - has conveyor chain with grip which extracts articles by end from bottom of stack
Inventor: LOLLICHON ROBERT
IPC: B27M3/34
Filed: 1980-05-21
Abstract: The distribution feed is for thin components, particularly wooden slats, on a conveyor chain constructing packages. A storage container (1,5) accommodates a set number of components in a uniform stack(E) so that one end of one component is accessible from the bottom. This component end is deflected downwards and in the lengthwise direction by a vacuum (2) so that it can be gripped by an extractor (3), pulling it out at right angles to the conveyor chain, on which it is placed by a positioning jaw (4). It can comprise a box-type housing with an open bottom at which two freely-turning rollers are mounted, set back from the front wall.

Title: CRT with spot locating technique - has layer of transparent material over screen, internally reflecting light to sensor if deformed by finger pressure
Inventor: BROUSSAUD GEORGES
IPC: G06F3/037
Filed: 1980-06-30
Abstract: The cathode ray tube screen comprises a glass plate (101) coated internally with a lumiphore material (102) emitting light when a beam of electrons (103) strikes it. Outside the glass there is a layer of silicon material (105) on top of which a thin layer of plastic of refractive index 1.49 is laid. This in turn is covered with another layer of flexible silicon material (107), thicker than the first layer (105). If a particular point on the screen is touched, the thin layer (106) is deformed, allowing light to be reflected inside this layer. Once inside, the light is internally reflected and transmitted to a sensor at the side of the screen. Thus by using the scan timing of the beam, and the noted time of arrival of light at the side of the screen, the point may be located.

Title: Longitudinal cable sheath cutter - uses electronic control circuit to position cutting tool in response to transducer measured sheath thickness as cable passes through
Inventor: DUBOIS GILLES
IPC: H01B15/00
Filed: 1980-10-31
Abstract: The appts. uses an automated cutter which has its depth of cutting adjusted in response to sheath thickness, which is continuously monitored as the cable is drawn past the cutting unit. This method allows quick sheath removal with easy recovery of the sheath material for recycling. The thickness of the sheath (3) is measured by a transducer (6), for example an inductance type transducer, and the transducer output is accepted by an electronic circuit (CR) which provides a drive signal (11) to an actuator (8) which positions the cutting tool (2). The position of the actuator is monitored and fed back (7) to the controller circuit (CR) for precise positioning of the cutting tool, in response to set input (10) and transducer data.

Title: Pick for earth cutter - has tip for use on leading edge with additional tips behind and covered with soft material
Inventor: REYNOLDS JOHN MICHAEL
IPC: E02F9/28
Filed: 1980-11-28
Abstract: The cutter pick for use in earth cutting apparatus has one cutting tip (2) exposed ready for use on a leading edge (4) of the pick body (1). One or more additional cutting tips (3) are also located in the leading edge though spaced from the first cutting tip and each other.

Title: Gas-fired oven burner - has bracket with vertical sleeve forming mixing chamber round nozzle
IPC: F24C3/08
Filed: 1981-06-15
Abstract: The burner is for a gas-fired oven or boiler plate, having a bracket for the fuel nozzle and a cover (12) forming with it a mixing chamber for gas and primary air, together with a flame-divider body with holes. The bracket has a vertical sleeve (6) forming a mixing chamber (5) enclosing the nozzle (1), together with a peripheral flange (8) forming a sealed joint with the oven support plate (9). The cover above the sleeve has a central tubular portion (14) enclosing a passage (15) concentric to the chamber, and a peripheral portion extending outwards and downwards near to the plate to form a primary air inlet (18) all the way round, while passages (16') in it lead to the mixing chamber. The cover supports the flame-divider body (13), which is above and extends outwards beyond the tubular portion, and the intervening space between cover and body leads to a peripheral passage (22). Thus as the mixture of gas and air flows from the passage (15) to the drillings in the body its speed is reduced and pressure is raised again.
