Abstract

945,498. Burglar alarms. COMPAGNIA ITALIANA WESTINGHOUSE FRENI E SEGNALI, and G. PRETINI. Sept. 16, 1960 [Sept. 24, 1959], No. 31959/60. Heading G4N. The double walls of a safe enclose a cavity 16 fed with fluid under pressure through a conduit 9, valves 20 and 25, and a conduit 42, the fluid being fed also to tanks 36 and 38 which are arranged to operate an acoustic alarm 51 and a protection assembly (consisting of one or more bottles 31 of smoke or tear gas and a plunger 18 which shuts the safe door 5) if the pressure in the cavity 16 falls because of damage to the walls or opening of the door 5 (and consequent release of fluid through a valve 17); the equipment is put into operative or inoperative condition at predetermined times by means of the electropneumatic valve 25 under the control of a time switch 45. The equipment is set in readiness by temporary manual operation of a valve 21, causing operation of valves 20 and 32 which are released if the pressure in conduit 42 falls. In a modification, the operative medium is a vacuum instead of fluid under pressure.
