Patent GB-2292850-A (GB)
Title: A switching device
Inventor: MELTON DAVID LAURENCE
IPC: H01H37/74
Filed: 1995-08-23
Abstract: In order to switch off electrical power to an appliance in which a fault develops leading to a temperature rise, a temperature sensor 18 is placed in the appliance 12 and is connected to a switch module 16 which is positioned as an interface between the mains and the appliance. When the sensor senses an increased temperature, it causes the switch module to go open circuit and thus to disconnect the appliance from the mains. The switching module 16 comprises a plug and a socket for connection of the appliance to the mains supply. In one embodiment the temperature sensor may consist of a flexible tube 18 made of a thermoplastic which contains a fluid under pressure. Excess heat causes the tube to rupture releasing a pressure switch which cuts off the mains power. In another embodiment the tube 18 may hold a fire extinguishing fluid. In a further embodiment the temperature sensor may also comprise a temperature sensitive conductor including one or more thermal fuses. <IMAGE>

Title: Safety switch assemblies
Inventor: MOHTASHAM MEDI
IPC: H01H27/00
Filed: 1994-10-20
Abstract: A safety switch comprises a housing containing electrical contacts movable from a power supply OFF position to a power supply ON position by rotation of an actuating cam assembly. An actuator of a predetermined configuration is insertable within the housing to rotate the cam assembly, causing movement of a cam plunger which moves the electrical contacts between the on and off positions. Locking members are actuable by a sliding plate operated by a solenoid which is controlled by a control button. In a locked position the locking members engage the plunger such that when an attempt is made to withdraw the actuator from the switch movement of the cam plunger and consequent cam rotation is prevented. In an unlocked position the locking members are pivoted by energising the solenoid to release the cam plunger and thereby to allow withdrawal of the actuator.

Title: Portable telephone loss alarm
Inventor: PARK TAE-GUEN
IPC: H04M1/72448
Filed: 1996-06-21
Abstract: A portable telephone has a loss-alerting mode which when set, initiates a timer and counter in a control unit that determines whether the number of originating calls made from the telephone, or the time elapsed, since the loss-alerting mode was set exceeds a respective preset limit. If so, an audible alarm is given and a password request message is displayed. The loss-alerting mode is released if a password input in response to the request is the same as a previously registered password. If it is not then the owner's address and/or telephone number is displayed and call origination and reception is blocked. When a call originating key is operated, a previously registered owner telephone number is dialled. Thus the owner of the telephone is automatically alerted to the fact that someone has the lost telephone.
