Title: Analogue to digital conversion apparatus
IPC: H03M1/44
Filed: 1971-03-19
Abstract: 1382027 Analogue/digital converters DATA LABORATORIES Ltd 10 March 1972 [19 March 1971] 58830/70 Heading G4H An analogue/digital converter includes a first converter deriving the N most significant digital output bits which comprises a number of serial stages each having a V-shaped transfer characteristic and a second converter receiving at its input the analogue output from the last stage of the first converter and comprising 2<SP>M</SP> comparator stages to derive the M least significant bits of digital output. In one embodiment the unknown analogue input is applied via push-pull terminals 10, 11 (Fig. 3) to the first of a plurality of serially connected stages in the first converter. Each stage comprises, for each terminal, an operational amplifier OA1, OA2, each with two feedback paths via oppositely poled diodes. With a negative signal terminal 10, the amplifier output t is positive so that a diode D1 is non-conductive and no signal is applied from point t to junction J1. However diode D3 is conducting, due to the positive signal at terminal 11, so that a signal is applied from point r to junction J1 where it is added to a signal from reference source V R . Similarly junction J2 receives signals from point s and q for positive and negative signals respectively at input terminal 10, each signal being added to a signal from a negative reference source - y R . The digital output bit is derived by examining the polarity of the signals t and u at the amplifier output in a discriminator DSC, the resulting digital signal being in Gray binary code.  The output from the last series connected stage is applied as one input to 32 voltage comparators VDS1-VDS32 (Fig. 6) their other inputs being derived by tapping a potentiometer network PN. The outputs of the voltage comparators are decoded by logic circuit DLN to derive a 5-bit signal in Gray binary form. These signals may be converted to pure binary form. Overload detection may be provided by an auxiliary input converter stage, the digital output from which is used to form an overload warning signal.

Title: Electronic time reaction game apparatus
IPC: A63F9/00
Filed: 1978-09-28
Abstract: An electronic time reaction game apparatus which may be played by one or more players comprises a pair of opposed player ends and an electronic processing means, such as a microprocessor, located in the housing. Two player actuable response switches and a plurality of player response lights are located at each player end. One of the response switches is forward acting and the other is rearward acting. The microprocessor initiates a game by generating a player ready signal and, after a randomly varying time interval, generates a player start signal. The ready and start signals may be visual or audible or both. The player or players must anticipate the action of the opponent player and select and actuate the proper one of their response switches to maximize their score, and after the start signal, each actuates their selected switches as quickly as possible. The score is depicted by one or more of the lights at the end of the player first actuating the forward response switch and extinctions of one or more lights of the end opposite the player first actuating a rearward response switch. <IMAGE>

Abstract: Apparatus feeds a web 23 of metal foil or other dead-fold material, cuts lengths of the web to size and positions the leading edge of a cut sheet 32 of foil in advance of the leading edge 14a of a tray 11 having a peripheral flange lip around its top. The tray 11 is advanced on a continuous conveyor 16 and its leading edge pinches the leading corners 38 of the sheet 32 between the underside of the lip and stationary blocks 36, one on each side of the conveyor 16. Next a plate 47 having an aperture 48 slightly larger than the tray is caused by cranks 44 to move with the tray and also down over the tray, bending the foil downward. in one embodiment, at each corner of the plate aperture 48 is an L-shaped bar 56 which is actuated to move diagonally inward, tucking the foil securely under the tray lip. Actuation of the L-shaped bars may be mechanical, pneumatic or electro- mechanical. In another embodiment, Figures 9 and 10 (not shown), said tucking under of the foil is effected by a blast of air from an aperture tube surrounding the aperture 48. After the foil has been tucked under, the plate 47 is lifted above the tray. A smaller plate 51 may be spring mounted in plate aperture 48 to level the contents of the tray during wrapping of the foil. <IMAGE>
