Patent GB-2239569-A (GB)
Title: Engine starting device
Inventor: MINEGISHI MASAMI
IPC: F02N11/08
Filed: 1990-12-12
Abstract: When an ignition switch 1 is closed to its engine starting contact ST, a signal passes via an OR gate 10 causing a circuit 6 to provide an ON signal to a driver circuit 8, whereby a starter motor 13 is energised. Rotation of the engine is detected from the output of a generator 4 which is caused to charge a capacitor CS to a voltage dependent on the engine speed. When the engine speed exceeds a reference, an overrun prevention circuit 7 sends an OFF signal via OR gate 11 to circuit 8 to deenergise motor 13. OR gate 10 also has an input which goes high when circuit 7 senses engine notation. Restarting of the motor 13 is therefore inhibited until both switch contact ST is opened and the engine has stopped. If engine rotation cannot be detected by circuit 7, a transistor Q4 in a backup timer 9 is held OFF so that a capacitor C7 in an RC timing circuit R19, C7 begins charging, whereby after a certain time a comparator IC2 sends an alternative OFF signal via OR gate 11 to circuit 8 to deenergise motor 13. <IMAGE>

Title: Improvements relating to thermally-responsive controls
Inventor: O NEILL ROBERT ANDREW
IPC: H02H5/04
Filed: 1992-07-02
Abstract: An electrical appliance (1) is protected against overheating by the provision of a plurality of series-connected, auto-reset type thermal cut-outs (2) each located in the appliance in the region of a potential hot-spot, and by the provision of a thermal relay comprising a bistable thermally-responsive switch (3) connected in the main power supply line of the appliance and a heater (4) associated with the switch and connected so as to be energized in the event of any of the cut-outs going open circuit. The thermally-responsive switch (3) will thus operate, due to heat generated by the heater (4) and after a certain time delay, in response to any of the cut-outs (2) operating in response to local overheating. The cut-outs (2) can be located at relatively inaccessible regions of the appliance and do not have to be accessed to be manually reset, and the thermally responsive switch (3) can be located in a readily accessible prominent position. This arrangement overcomes the problem of having to have the appliance attended to by a service engineer whenever a cut-out nuisance trips in response to a transient condition, as is the case conventionally when non-auto-reset type cut-outs are employed. <IMAGE>
