Abstract

1,012,068. Temperature alarms. MAINTENANCE CO. Inc. Aug. 21, 1963 [Sept. 10, 1962], No. 33107/63. Heading G4N. [Also in Division G1] The invention relates to control apparatus responsive to changes in its environment such as in ambient light or temperature changes due to a fire, and consists of a rechargeable battery having across it a voltage divider which responds to the said changes to vary the voltage at its tap, and switching means in series with a device to be controlled, the switching means and the device being connected across the battery, the tap being connected to the switching means to activate it and allow current to flow through the device upon the occurrence of an environmental change. The figure shows an emergency lighting circuit for lighting an emergency lamp 36 in the event of failure of the local lighting or power and includes a battery 26 which is continuously trickle charged by a transformer acting through a half-wave rectifier 30. When the local lighting is on the resistance of a cadmium sulphide photo-resistor 44 is low compared with a resistor 42 so that the voltage drop across the photo-resistor 44 is also low. When the local lighting is absent the resistance of the photo-resistor rises and the voltage at the tap 46 becomes sufficient to cause a silicon controlled rectifier 40 to fire and thus light the emergency lamp 36. Capacitors 38 and 50 prevent triggering of the rectifier 40 due to transient conditions. In a further embodiment (Fig. 2, not shown), the silicon controlled rectifier 40 is used to trigger a high current silicon controlled rectifier which is connected in series with a heavy lighting load. The photo-sensitive resistor 44 may be replaced by temperature-sensitive resistor to detect fires and the silicon controlled rectifier in this case operates an aural fire alarm or fire control equipment such as sprinklers. The temperature-sensitive resistor and the resistor 42 may be interchanged to enable the apparatus to be used to monitor cold storage rooms to prevent freeze damage to food products. The photo-resistor could be placed in a smoke collecting chamber and normally illuminated by a source across the chamber. In the presence of dense smoke the light falling on the resistor would be reduced sufficiently to actuate the circuit. To sense humidity the photoresistor could be replaced by a suitable moisturesensitive device.
