Patent FR-2454148-A1 (FR)
IPC: G09B29/00
Filed: 1980-04-09
Abstract: An information board (see Figs. 1 and 2) for the formation of signs such as figures, letters, patterns etc. According to the invention the device comprises a greater panel (1) and a smaller panel (2), a first of which includes a chequered pattern with transparent fields (4) surrounded by white (5) or black (3) fields of substantially the same size as the transparent fields, and a second of which includes a chequered pattern with black fields (3) surrounded by white (5) or transparent (4) fields where the first panel (1) is located closest to an observer. The panels (1, 2) are arranged close to and above one another and are movable relative to each other in a direction in parallel with a side of a field (3, 4, 5) at least through a distance corresponding to a side of a field (3, 4, 5).
Patent FR-2454670-A1 (FR)
IPC: G04G5/04
Filed: 1980-04-11
Abstract: A multistage counter 3, 5, 7, 10 normally counts seconds pulses from a frequency divider 2. Counters 5 and 7 are units and tens minutes counters and are set by shifting a counter 21 by button B to provide a "1" on output 21d. When a button A is then held down the seconds pulses pass through gates 17 and 22 and count the units counter 5 up to the numeral 0. A flip-flop 19, 26 is then set to disable gate 22 and enable gate 23 so that the units counter stays at the numeral 0 and the tens counter advances to the desired value, when button A is released, which resets the flip-flop. Button A is pressed again to count the units counter from the numeral 0 to the desired value. The invention in one embodiment simplifies the setting of a digital watch and reduces the time (number of pulses) needed to preset the units and tens of minutes counters. The invention can be extended to more than two counters and used for counters other than in clocks and watches.

Title: Thermoluminescent imaging device for x=ray pictures etc. - avoiding chemical developing, printing etc. of pictures
Inventor: GASIOT JEAN
IPC: G21K4/00
Filed: 1980-05-20
Abstract: Device consists of a thin film of thermoluminescent material. The material is sensitised by exposure to an image using X-rays, gamma-rays or other ionising beams (neutrons, etc) and the image received is read using an infra-red laser beam by passing the beam into the thermoluminescent material to heat it momentarily so that light is emitted which is converted into electrical signals and reproduced on a television screen. The method is useful for obtaining pictures by Radiography and gamma radiography for industrial or medical purposes, neutron radiography for industrial purposes and for use in locating components in a nuclear reactor, etc. The method can give an instant, or not long delayed image and does not require complex appts., chemicals, etc. to produce the image on film. The information is not degraded by reading as in some prior art methods.

Title: Oil-bath drying process for wood - involves microwave heating whilst immersed in oil and under vacuum
IPC: F26B5/04
Filed: 1981-06-24
Abstract: The process for drying wood and other organic products takes place under vacuum in a warm drying medium, preferably oil. The boiling point of the oil is sufficiently high for fulfilling the drying process and sufficiently low for its evaporation from the wood surface after the drying process. As a heating source (wholly or partly) dielectric energy is used, within a high frequency range such as the GHz region. The dielectric energy may only be introduced during the later part of the drying process. Preferably the dielectric heating is started or is accentuated at about the time when the oil is taken away from the drying cylinder.
