Title: Movable Element Control System
IPC: G06K15/04
Filed: 1967-03-06
Abstract: 1,181,692. Automatic control of speed. INTERNATIONAL BUSINESS MACHINES CORP. March 6, 1967 [March 28, 1966], No.10381/67. Heading G3R. The speed of a reversible motor PCM, e.g. driving a type bar in a printing device, is controlled by a system in which, when the motor is slow, a bi-stable "accelerate trigger" 38 is gated on by reference pulses (from single shot device 40) and off by motor speed pulses (from magnetic disc 34), and when fast a "decelerate trigger" 46, which causes reverse energization of the motor, is triggered on by the motor pulses and off by the reference ones and hunting is reduced by means not shown in Fig.2. The motor, which is of printed circuit construction, is energized from a D.C. source via transistors which are switched by the trigger circuits Fig.6 (not shown). Hunting is reduced in Figs.4 and 7 (not shown) by an auxiliary circuit which causes the motor to be energized continuously for a predetermined brief time in a direction which hastens correction; this occurs upon the second trigger pulse following a change from accelerate to decelerate or vice versa. The complete system comprises logic circuitry and photo-cell detectors of print bar position, and provides for the motor to be accelerated from rest by continuous energization for a predetermined time and to be similarly decelerated to stop beyond a predetermined position, the stopping point being such, that, upon reversal, the print bar will have aquired full speed by the time that position is reached. The reference single shot device 40 is operated by sub-division of pulses from a clock 42, the sub-dividing counter also being used to determine the starting and stopping time. A "checking circuit" (100) comprising further logic devices de-energises the motor in the event of typebar jam, feedback or amplifier failure, clock failure or failure of the triggers to reset, and the motor drive circuit includes biasing of the transistors to prevent simultaneous energization in both directions.

In an EHT supply for a cathode-ray tube of the type in which the current in an inductor is periodically interrupted by means of an electronic switch 7, controlled by a sawtooth waveform 17, the EHT voltage is stabilized by variation of the steep flank of the sawtooth wave 17. As shown, a line output valve 7 or transistor is periodically interrupted by a sawtooth voltage on the grid generated by the periodic charging and discharging of capacitor 6 via valve 1, overdriven by a sine wave 2 on the grid. The flyback pulses developed in winding 11 are rectified at 12 so as to provide the EHT voltage. An energy recovery circuit 9, 10 is provided. The EHT current is monitored by resistors 13, the flyback pulses being by-passed by diode 15, and after smoothing, applied to the base of transistor 16 so as to control the discharge current of capacitor 6 and hence the slope of the steep flank of the sawtooth voltage 17 fed to the grid of valve 7, so as to stabilize the EHT voltage against changes in load current. This action causes a corresponding change in the width of the flyback pulses so that if lower voltage flyback pulses are rectified for the production of focusing voltage, the ratio between EHT and focusing voltags remains contant. A positive-going control voltage + U1 is available if device 16 is replaced by a NPN transistor or thermionic valve. In Fig. 4 (not shown) transistor 16 is replaced by a thermionic valve, shunted by an inverse diode and connected in series with the grid of valve 7.
