Abstract: 1,037,117. Automatic voltage control. ZENITH RADIO CORPORATION. June 19, 1964 [July 1, 1963], No. 25572/64. Heading G3R.[Also in Divisions A5, H2 and H3] An electrical defibrillator which is portable and operated from a battery 10 includes a charge and discharge circuit 15 which is able to deliver to electrodes 16,17 placed on or over a patients heart a direct-current output pulse having a trapezoidal waveshape. As described, energy from the battery 10 is inverted to A.C.and amplified by a circuit 12, the voltage is increased by a transformer 13, and it is then rectified in a silicon diode circuit 14 to give a controlled charge to a two or more section delay line 34, 35, 36, 37 which is discharged on demand by actuating switches 39, 40. A control circuit 18 including transistors 47, 59 maintains and controls the replacement of charge on the condensers 36, 37. As shown, with the switch 29 open a bias from the primary winding 21a and rectifier 43 maintains the transistors 23, 24 non- conducting and prevents charge being supplied to the delay line. However if charge is lost the potential across resistor 56 drops and the transistor 47 becomes non-conductive and the transistor 59 conductive, and the resultant current flow in coil 30 closes switch 29 allowing the transistors 23, 24 to conduct and charging of the delay line to take place to the predetermined limit. Chattering of the relay 30 is avoided as a result of the reduction of the emitter bias supplied through the resistor 62, due to the closing of contact 29.

Filed: 1921-09-30
Abstract: 190,812. Graseby, R. C. Sept. 30, 1921. Clockwork - actuated valves.-An electric igniting means for gas burners comprises clockwork-actuated means for opening a valve 12 in a pipe 11 supplying gas to the burner and simultaneously setting in motion a pendulum 9 adapted intermittently to close the igniting circuit for a period limited by the decreasing amplitude of the oscillations of the pendulum. The device is operated by a, clockwork-actuated arm 3 which, in its rotation in a counter-clockwise direction, displaces a. bellcrank 17 about its pivot 18, thereby depressing a lever 28 until a catch 30 thereon engages a stop 31 on a pivoted lever 32. At the same time, a notched lever 21 pivotally connected to the bellcrank 17 at 20 displaces in its horizontal movement the pendulum 9 which carries a contact 6 co-acting with a contact 5 carried on a flexible blade 7. As the arm 3 clears the end of the bellcrank 17, the latter is returned by a spring 19, thereby raising the pivoted lever 32 and lifting the valve 12 through the medium of a link 34, bell-crank 14 and valve stem 13. The pendulum is simultaneously released by the return of the lever 21, thereby causing igniting sparks at the burner by the intermittent closing of the contacts 5, 6 during the oscillation of the pendulum. The gas may be automatically shut off by an arm 4 rotated by the clock mechanism which arm is adapted to tilt the lever 28 against a spring 29 so as to release the lever 32 which is then returned to the horizontal position by a spring 35 thereby closing the valve 12.
