Title: Power supply
Inventor: LUCAS JAMES
IPC: H02M1/08
Filed: 1983-09-21
Abstract: A power supply capable of providing a high current output without requiring a heavy power transformer comprises a resonant LC circuit, L1, C1, and a switching transistor Q1 connected in series across a d.c. supply +Vs, Vo. The transistor is switched on by pulses from a pulse generator 11 to periodically feed power to the LC circuit. A monitor device such as a microprocessor MPU monitors the voltage V1 across Q1 via an analogue/digital converter A/D and controls the pulse generator 11 so that the period of the pulses fed to Q1 varies in step with the period of oscillation of the LC circuit. Thus, when the load coupled to the LC circuit via a link winding L2 varies, the power output is maintained. The width of the pulses may also be controlled by the microprocessor via a pulse width modulator 12, to control the power output of the supply. <IMAGE>

Patent GB-872307-A (GB)
IPC: G07C1/18
Abstract: 872,307. Selective punching-machines. BUD, M. July 7, 1959 [April 11, 1958], No. 11570/58. Class 31 (2). [Also in Group XIX] Time-recording apparatus comprises a plurality of punches for marking in binary code a card positioned in a guide and punchactuating projections on wheels rotated step by step by time mechanism so that when the wheels are moved towards the punches the coded marks, produced on the card by the punches selected by the operating projections, represent the time set up on the wheels. In a workmen's time recorder, an electric motor 301 causes micro switches 304, 305 to close at minute and twelvehourly intervals respectively. Minute pulses to an electromagnet 25 cause stepping of a units wheel 3 and transfer mechanism carries the drive over to wheels 4, 5, 6 in turn. Twelve-hourly pulses to electromagnet 31 cause the wheels 3, 4, 5, 6 to return to initial position and to electromagnet 114 cause stepping of a wheel 100. Each wheel 3, 4, 5, 6, 100 carries projections 38, 118, 119 so that when either micro switch 66, 67 is closed when clocking " on " or " off " an electromagnet 45 causes certain punches in the assembly 200 to be actuated by those projections of the actuating wheels for the time being in operative position. Each wheel 3 to 6 completes a revolution in eight steps and is justified in each of its eight positions. With the arrangement of projections spaced round the peripheries of the four wheels shown in Fig. 6, their positions at any time represent elapsed time in binary code. The wheel 100 turns in fourteen steps and the position of the projections 119 represents the days or nights of the week. The projections 118 actuate a punch every time a card is punched and an interposer 236 enters this hole on the subsequent insertion of the card in the guide 217 to limit its passage and cause punching on a new line. When clocking on, a button 62, Fig. 3, is pressed to close the micro switch 67 and also pushes the actuating wheels and punch assembly laterally relative to the card holder; lateral movement in the opposite direction on clocking off is caused by pressing a button 61 which also closes the micro switch 66. Thus IN and OUT records are offset and can be distinguished when the cards are read or sensed. Safeguards are provided against simultaneous punching and setting.
