Title: Improvements in or relating to multivibrator circuits
IPC: H03K3/08
Filed: 1946-05-15
Abstract: 612,539. Pulse generating circuits. PHILIPS LAMPS, Ltd. May 15, 1946, No. 14698. Convention date, March 10, 1942. [Class 40 (vi)] In a multivibrator comprising two valves which are cross-connected in the normal manner, a short build-up and decay time of the output pulse is produced by supplying at least two similar output electrodes of the valves from a common voltage source via a common resistor. In the Figure, the multivibrator circuit shown operates in the normal manner except that the inclusion of resistors 25 and 25<1> in the common supplies to the anode and screen circuits reduces the time interval between which one valve just commences to conduct and the other valve is just completely blocked. When valve 1 just starts to conduct, not only is the potential of control grid 12 reduced by virtue of the cross-coupling 10, but as the screen current of valve 1 increases the potential of screen grid 8 is reduced by reason of the increase voltage drop across the common resistor 25<1>, in a similar manner the increase in anode current of valve 1 increases the voltage drop across resistor 25 and thus reduces the voltage of anode 2. The resistors 25 and 25<1> are preferably approximately equal in value to the resistors 17, 18 and 13, 14 respectively.

IPC: F02M1/00
Filed: 1917-10-11
Abstract: 119,888. Donning, G. W. Oct. 11, 1917. Thermally-actuated valves.-In engines for use on motor-vehicles, motor-boats, aeroplanes, and like vehicles which at times travel in comparatively low temperatures, the air supply is heated by exhaust gases and electrically; the temperature of the air is controlled by a thermostat in accordance with the temperature of the cooling- water of the motor itself, or of the surrounding air; the action of the thermostat may be manually controlled, and, in the case of a motor-vehicle, the bonnet space is ventilated by a, valve actuated by the thermostat. The invention is shown applied to a motor-vehicle in which the engine 1 is enclosed in a bonnet 34, the cooling system comprising a radiator 2 and pipes 3, 4, the pipe 3 including a box 42 containing a thermostat 41. Air is supplied to the carburettor through pipes 20, 54 from chambers 49, 50 surrounding the exhaust pipe 6. The chamber 50 is separated from chamber 49 by a partition 48 with flap valve 55 and supplies air only when the suction is sufficient to open the valve 55. Air enters the chambers through ports 51, 52. The pipe 20 has two additional inlets 21, 22 provided with hinged valves 24, 25 actuated by arms 29, 28 connected by link 30. The arm 29 is further connected through link 31, bell-crank 32, link 35. and bell-crank 38 to the rod 40 of the thermostat 41. Upon an increase of temperature the valves 24, 25 are opened so as to admit cool air through the opening 22 and at the same time allow the hot air from the pipe 54 to escape through the opening 21. An electrical heating-coil 59, supplied with current from a battery 60 through leads 63, 64, 65, may be used at starting or during normal running. The circuit has a hand-switch 66 and a spring switch 71 carried by an arm 69 on the spindle of the valve 25. With this arrangement the circuit of the heating-coil is controlled by the thermostat 41, the action of which may be retarded more or less by providing on the arm 69 a rod 72 with a resilient section 73. the outer end of the rod being adjustable by a latch 74 and holes in a fixed part 75. The thermostat may actuate also a valve 77 in the bonnet 34, through links 78, 79. In modification the thermostat 41 is mounted directly on the engine cylinders.
