Title: Rubber seal profile for a French window - to prevent internal spillage of penetrating moisture
IPC: E06B7/23
Filed: 1974-11-27
Abstract: Seal profile for use along the base of a 'French window', comprises a 'J' section profile with a cranked lip facing outwards. When the door is closed, the capacity of the lip is reduced by compression against a fixed frame: when the door is open, the lip distends elastically to contain any trapped water at a level lower than the lip. The seal retains trapped water entering by capillary action without risk of spillage as the door or window is opened into a building. Seal is less fragile than sprung metal leaf seals.

Title: Safety switch for communication circuit with current sensitive release - transmits snap action to contacts via spring loaded link mechanism actuated by coil
IPC: H01H73/56
Filed: 1975-04-18
Abstract: Safety switch for telecommunication circuit with a current dependent release mechanism (48, 49) which transmits the snap action to the contacts.

Patent FR-2280162-A1 (FR)
IPC: G04C10/00
Filed: 1975-07-23
Abstract: The liquid-crystal display device includes electrodes (2a and 3a) deposited in the form of transparent layers on the internal faces of the upper and lower plates (2 and 3).

Title: Expressing filter plate - with diaphragm filter sheet having fluid passing opening protected against constriction or blockage
Inventor: KURITA TETSUYA
IPC: B01D25/21
Filed: 1976-05-04
Abstract: Expressing filter plate for a filter presS, comprises 2 base plate covered by a diaphragm sheet having a filter surface and formed with a fluid passing opening communicating with a filtrate or wash liquor passage in the base plate. A cover made of material of higher hardness than the diaphragm sheet has a tubular portion which fits in the fluid passing opening to provide a fluid inlet or outlet. Since the tubular portion is harder than the sheet it retains its shape without expanding inwardly towards the centre when the sheet is subjected to press. on its opposite surfaces. Thus the fluid passing opening will not be constricted or blocked due to plastic deformation.
Patent FR-2311343-A1 (FR)
IPC: G04G99/00
Filed: 1976-05-06
Abstract: A digital watch with oscillator/divider power selection circuitry. The selection circuitry selects the source of the voltage to be supplied to the crystal oscillator and initial divider circuits. If battery voltage is low because battery current is high, as when the light emitting diodes (LED's) are illuminated in an LED digital watch or when the illumination light is on in a liquid crystal display (LCD) digital watch, the crystal oscillator and initial divider would be powered by two batteries; and when battery voltage is high because battery current is low, the crystal oscillator would be powered by only one battery. Therefore, the power selection circuitry determines whether one or two batteries are used to power the oscillator depending upon the particular operating conditions. There are two advantages of this technique: (1) current is reduced so battery life is increased, and (2) the voltage never goes so low that circuit production yields are adversely affected.

Title: Electrode assembly for accumulator batteries - has header welded to frame channel sections holding long strips clamping active mass filled tubes
Inventor: GUGLIERI MICHEL
IPC: H01M4/76
Filed: 1976-09-02
Abstract: The electrode assembly for accumulator batteries comprises a basic frame member of metal having a U-channel profile (12). The member has nicks (13, 14) at two places at which it is folded inwards to form a three-sided square frame.

Filed: 1977-01-21
Abstract: Prodn. of lubricating oils and greases by dispersing thickners, additives and fillers in base fluids is carried out by means of ferromagnetic particles which form a vortex under the influence of a rotating magnetic field. The ferromagnetic particles can be of a magnetically soft or hard material (e.g. carbon steel, Ni or Co/Ni alloys) with a ratio of max. to min dimension of 6-20:1. The particles are pref. protected by a polymer coating. In the case of dispersing thickeners (e.g. metal soaps), these can be formed in situ by reaction of appropriate starting materials. High quality products can be produced in treatment times of a few seconds. Energy consumption is low. The process can be operated continuously and is readily automated.
