Abstract: ABSTRACT         A hand-held scanning device is moved across a line of print and generates a two-dimensional scan of the print. A line array of photo diodes performs the scan in one direction and the movement across the paper generates strobe pulses each of which allows one scan of the array to be passed to a store from which a domestic T.V. set can be fed to provide an enlarged dis-play. May be used as a reading aid for partially sighted people or as an input device for an optical character recognition machine. In the case of a reading aid using a T.V.-type raster display, the store is organized to allow new array scans to be written in at a variable rate dependent on hand motion while the contents of the store are read out repetitively and non-destructively at a constant line-by-line rate suitable for the T.V. raster.

Abstract: TITLE          ELECTRONIC AUTOCLAVE TIMING CIRCUIT   FOR KIDNEY DIALYSIS APPARATUS                         ABSTRACT              Disclosed herein is an improved electronic control system for the autoclaving sequence of a kidney dialysis machine, during which water is circulated at high temperature and pressure to clean and sterilize the machine.  The circuit ensures that the machine will be autoclaved for a minimum period of time, such as 20 minutes, measured only while the temperature is above a minimum, such as 120° centigrade.  The circuit will remember the time of autoclaving previous to a power interruption, and will continue to time the autoclaving function only when the temperature has again exceeded the set minimum.  Once an autoclaving sequence is initiated, the circuit prevents normal use of the machine until the sequence is completed,  During the autoclave timing sequence, the kidney by-pass solenoid is energized and de-energized on a 50% duty cycle to make sure all flow paths in the machine are cleaned and sterilized.                              -1a-

Abstract: MEASURING-WHILE-DRILLING METHOD AND SYSTEM        HAVING A DIGITAL MOTOR CONTROL                 ABSTRACT OF THE DISCLOSURE    A measuring-while-drilling system has a digitally implemented motor speed control circuit for controlling a downhole, motor-driven acoustic signal generator.  The acoustic generator is motor driven at speeds for imparting to well fluid an acoustic signal having phase states repre-sentative of encoded data derived from measured downhole conditions.  The digital motor control circuit drives the motor at a substantially constant, carrier frequency pro-ducing speed in the absence of data of one logic state and temporarily changes the speed of the motor to effect a predetermined phase change in the carrier signal upon data of the predetermined logic state.  For returning the motor speed to the carrier frequency producing speed during phase changes, the digital motor control circuit includes a first digital integrating circuit for providing a first digital signal having a value indicative of the constant value of the carrier frequency integrated over a time period be-ginning substantially upon the occurrence of the particular data; it has a second digital integrating circuit for providing a second digital signal having a value indicative of the instantaneous speed of the acoustic generator inte-grated over the time period; and it has a digital comparator which is responsive to the first and second digital signals for generating a control signal effective to change the speed of the motor when the difference between the first and second digital signals reaches a predetermined value.
