ALARM DEVICE Russian patent published in 1994 - IPC

FIELD: signaling devices. SUBSTANCE: device has slope detector, which has case and cap forming air-tight space. Two cylindrical electrodes - internal and external - are disposed one inside the other and separated by insulating bushing in the case. Sensitive element, made in form of conducting ball, is disposed onto internal cone-shaped surface of external electrode. Winding 9 is disposed onto rear part of external electrode. The external electrode is disposed in light-melting-point material (for example, paraffin), which fills the lower part of air-tight space. External and internal electrodes are suspended vertically in air-tight space by three flexible wires, which come out of three symmetrically disposed contact areas of isolating bushing. The areas are connected with external electrode, with internal electrode and one end of winding, which has the second end to be connected with external electrode. Wires are removed from air-tight space through hole in the cap and are fixed after electrodes are suspended vertically. Device has flip-flops, counter, OR gates, AND gates, pulse generator, switches, inverters, actuating unit, make contacts, buttons, reed relay, time-setting circuits, light-emitting diodes, load resistors, decoupling diodes, positive and negative buses of power supply. Positions of internal and external electrodes are restored automatically independently of slope of automobile. EFFECT: improved reliability of operation; widened area of application; improved quality of protection. 1 dwg
