Title: Method of Validating Data Stored in Read-Only Memories
IPC: G06F11/10
Filed: 1980-07-26
Abstract: Signature analysis is used to validate the contents of a store. Signature analysis is a technique based on the time-honored technique of signal tracing in which lengthy bit streams are converted into short four digit hexa-decimal "signatures" in a linear feedback shift register which is clocked by the same clock as the bit stream under test and the bits summed modulo 2 by the register feedback. The resulting "signature" of the tested bit stream is compared with the correct "signature" and any deviation from the required signature will indicate a bit error which can then be traced. The invention applies the technique of Signature Analysis in the verification of the contents of PROM's by driving a PROM put under test from a pulse driven binary address counter and converting PSC the PROM output to serial form before application to the signature analysis feedback shift register DOR/SR. The use of 4 digit signatures allows unique identification of PROM's up to 65 K bits in size, whereas five digit signatures would check PROM's up to 1 M bits in size. <IMAGE>

Title: Television cameras
IPC: H04N9/76
Filed: 1980-08-01
Abstract: Where a plurality of television cameras 11, 12,...,1n are used, the output video signals therefrom are used after being sequentially switched, mixed or superimposed so as to give a special effect to a reproduced picture, and the resultant video signals are recorded on a video tape recorder 31, it is necessary that the relations between the output video signals from the cameras 11, 12,... 1n or synchronization of the output signals, phase relation of the sub-carriers of the chroma signals thereof, magnitude relation thereof, black level relation thereof, white balance and so on are made coincident. To this end, a camera control unit 3 is provided externally which produces a data signal to establish the above coincident relations between the signals. This data signal is used to control a microcomputer 15 provided in each of the cameras 11, 12,... 1n and hence positively to control the respective video conditions. Moreover, in the case where one television camera 1, and one video tape recorder 2 are directly coupled to each other, the operation of the system control circuit 27 of the video tape recorder 2 is controlled by the camera 1 and the fade-in and fade-out operations of the output signal from the camera 1 in synchronism with this control can be simply carried out by means of the microcomputer 15. <IMAGE>

Title: Work holding device for the turret of a turret lathe
IPC: B23Q7/04
Filed: 1980-10-09
Abstract: The device 9 for the turret 22 of a lathe cooperates with the chuck of the lathe to drive the workpiece in order to prevent a deformity being formed on the workpiece when parting-off from the remaining length of stock. The device comprises an attachment including a body 30 having a bore housing a hollow spindle 39 within which is located a collet 38, the sleeve 37 of which is operated by a piston 34 which is also used to operate a workpiece ejector 48. An air motor 47 is used to rotate the spindle and collet. The piston is rotary or non-rotary. A ratchet on gearing from the motor, or a spring-biassed, air-retracted stop prevents rotation of the workpiece when required e.g. for subsequent machining operations upon turret indexing after parting-off. The attachment drive may be a flywheel which is energised by the initial workpiece rotation by the chuck. <IMAGE>

Patent GB-2066532-A (GB)
Title: Coin counting system
IPC: G07D9/00
Filed: 1980-12-10
Abstract: A coin counting system for use with a coin handling apparatus such as a coin counting apparatus, a coin sorting apparatus or a coin wrapping apparatus includes a coin guide for guiding a series of coins to be counted therealong and a belt conveyor for conveying the coins in the guide. A light source is disposed at a downstream portion of the guide. Pre- and post-sensors are juxtaposed to each other upstream and downstream in the coin conveying direction and are arranged to receive the light from the light source and to be included temporarily within the generally triangular space, which is defined by the inner wall of the coin guide and by the facing circumferential portions of the two coins being conveyed adjacent to each other, thereby to generate respective signals. A generator circuit is made receptive of the signals of the two sensors for generating an addition signal, when the two coins pass in the normal order from the pre-sensor to the post-sensor, and a subtraction signal when the two coins pass in the abnormal order from the post-sensor to the pre-sensor. Structure is made responsive to the addition and subtraction signals of the control circuit for generating a count signal, when in the normal order, but not when in the abnormal order. A counter counts up the number of the coins in response to the count signal. Thus, the coin having been counted can be prevented from being erroneously counted up even if it is conveyed backward.
