Patent GB-192070-A (GB)
Abstract: 192,070. Bosch Akt.-Ges., R. Jan. 23, 1922, [Convention date]. Systems, electric; contacts, arrangement of external .-The depletion of the battery a, due to the ignition switch i and interrupter contacts c remaining closed when the engine stops, is prevented by arranging a thermostat in a shunt circuit. The uninterrupted passage of current allows the coil d to close the contacts c, and the consequent heating of the coil f causes the opening of contacts h in the main ignition circuit. The reclosing of the contacts h when the thermostat cools may be avoided if one of the contacts h is held against the other by a catch carried by the thermostat. A hand switch is provided for reclosing the circuit. In a second modification, the thermostat circuit remains closed when the ignition circuit is broken, its resistance being made suffieently high to prevent exhaustion of the battery. To reclose the ignition circuit the thermostat circuit is broken by a switch therein. A signalling device, operating simultaneously with the thermostat, is preferably provided to attract the driver's attention to the irregular condition of the ignition circuit.

Filed: 1972-04-25
Abstract: 1432567 Battery charging systems NV TOOLS Ltd 12 July 1973 [25 April 1972] 19211/72 Heading H2H A circuit for monitoring the charging current supplied to a main battery (not shown) comprises an internal battery 24 and an alarm 25 which is intermittently energized by the internal battery in the event of a mains supply failure, no output from the main battery charger or disconnection of the main battery. The internal battery which consists of six nickel cadmium cells is charged from a power supply 22 via a constant current transistor circuit 23. The charging current supplied to the main battery flows through a diode 26 and switches on transistors in a detector circuit 21 thereby energizing a relay coil 30 and disconnecting multivibrators 28, 29 from the battery 24. A driver circuit 27 therefore does not operate the alarm but in the event of failure of the main battery charging current the battery 24 is connected to the multivibrators, the higher frequency one of which, 28, supplies three mark pulses to the driver circuit during each space of the multivibrator 29 to sound the alarm. A link 31 enables testing of the alarm.

IPC: B01F3/04
Filed: 1922-07-17
Abstract: 202,809. Garrett, P. A. July 17, 1922. Actuating-mechanism.-A gas inlet valve 3 of an aerating-apparatus is actuated against a spring by a roller on a lever 45 acting on a ball 44, so that the valve cannot be held open, but only give a short sharp charge of gas. The lever 45 is so pivoted to a lever 2 that it opens the valve on moving upwards but slides over the ball 44 without action on moving down. The lever 45 may be replaced by a cam with sharp rises. The escape of gas from the aerating-chamber is controlled by a valve 35 operated by the lever 45 through a lever 31. In a slot in the valve 35 slides the stem of a valve 39 controlling the gas outlet from a chamber 15. When the valve 35 has moved a certain distance it opens the valve 39 through a pin-and-slot connection. If, however, the pressure in the chamber 15 becomes excessive it opens the valve 39 against the action of a spring without moving the valve 35.
