Inventor: RENE DOCHE
IPC: H01H33/00
Filed: 1993-09-14
Abstract: The present invention relates to a high-voltage circuit breaker capable of cutting off alternating fault currents of period T and with delayed zero crossing, passing through zero after a maximum time delay tzmax-t0 after the instant t0 of appearance of the fault, comprising a plurality of first cutoff chambers (1) in series each provided, at their terminals, with a distribution capacitor (2) of the same capacitance and equipped with means (3) for opening at an instant t1 later than the instant of appearance of the fault t0. It comprises at least one supplementary cutoff chamber (4) in series, equipped with means (6) for opening at an instant t2 after the instant of the fault t0 lying between tzmax-T and tzmax+T, the said supplementary cutoff chamber (4) being provided, at its terminals, with a distribution capacitor (5) having the same capacitance as the distribution capacitors (2) of the said first chambers (1).

Title: Thermally-sensitive, low-rigidity recording material - made from backing layer, e.g. of synthetic paper, with thin coating of thermally-sensitive substance
Inventor: KATSUNORI HIROISHI
IPC: B41M5/30
Filed: 1993-09-22
Abstract: The material is made from a backing layer, e.g. of paper, and a coating of a thermally sensitive colouring substance which is capable of changing colour when heat is applied to it. The rigidity of the coating substance is less than a specified limit when measured in a lengthwise direction, i.e. in line with the cellulose fibres of the backing material, or in a specified direction when the backing material contains no fibres. The thickness of the coating layer is 150 micrometres or less, and the backing material is preferably of a synthetic paper with polyethylene, polypropylene, polystyrene or PVC as its main constituent. Where it is made from plastic film it should be of low-density polyethylene or PVC, with a relatively low module of elasticity. The thermally sensitive coating can be made by mixing two liquids in a 1:3 ratio. The first liquid can comprise (parts by weight): 3-(N-methyl-N-cyclohexyl)amino-6-methyl-7-anilino-fluorane 10; 10 per cent polyvinyl alcohol solution 10; water 80. The second liquid can comprise: p-hydroxybenzyl benzoate 10; calcium carbonate 10; 2,2'-methylenebis (4-methyl-6-tert-butylphenol) 5; 10 per cent aqueous polyvinyl alcohol solution 20; water 55. ADVANTAGE - Rapid image recording without sound or environmental pollution, and lower manufacturing costs.
