IPC: G03G21/10
Filed: 1972-12-06
Abstract: 1375630 Cleaning sensitive surfaces INTERNATIONAL BUSINESS MACHINES CORP 6 Dec 1972 [22 Dec 1971] 56184/72 Heading G2H Excess toner is removed from the sensitive surface 11 of an xerographic drum by advancing the surface past a wiper member 50. The wiper is cleaned by a member 32 having a roughened surface 31 which is advanced past the wiper whilst applying a potential to the wiper to repel toner therefrom on to the member. As shown the member is carried on the xerographic drum but in an alternative form the member is stationary and a rotary wiper is arranged to contact the drum and the member. During cleaning of toner from the surface 11 an electrical bias may be applied to the wiper to attract toner thereto. The wiper may be polyurethane foam carried in a plastics 51 mounted on a conductive plate 53. An alternative wiper material is conductive neoprene. The member 32 may be a metal block having a grooved, knurled or flame-sprayed surface. The drum may be replaced by a xerographic belt having at one part of its surface a member 32.

The ends of the leads 13, 14 are bent back on themselves to engage the tape 16 so preventing their longitudinal movement relative to the bundle 11. Each lead may contain two insulated wires and one base earth wire. The tapes 16 may be coloured differently from tapes 12 to indicate that they may be cut to release leads 13, 14. The plurality of leads may be secured to a flexible non-conductive member to form a flat bundle, the tapes 12 being then not necessary.

Title: Apparatus and method for measuring dimensions
IPC: G01B11/28
Filed: 1971-12-21
Abstract: 1428949 Area or length measurement SHOE & ALLIED TRADES RESEARCH ASSOCIATION 2 March 1973 [21 Dec 1971 28 Feb 1973] 59354/71 and 9843/73 Heading G1A Apparatus for measuring a dimension of a first surface which contrasts with a second surface discriminates the signals corresponding to the two levels from the video signals produced by scanning the surface and registers a count corresponding to one of the discriminated signals via a scaling device which permits the count to represent the dimension directly in desired units. Both the final count and the scaling factor are displayed. The object to be measured is preferably dark relative to its background and the scanning is preferably by a TV camera with the intensity of the output signals being black > white > vertical sync. The video signal is applied at A. Amplifier 54 is set to separate the black level signals, which are shaped by Schmitt trigger 56 and applied to AND gate 32. Amplifier 34 selects the vertical sync pulses and these are filtered (36), shaped (38) and their frequency divided twice by two in bi-stables 40 and 42 to produce a signal (F) of pulse duration equal to one frame period which is fed to gate 32. The signal F is also differentiated (44) and fed to AND gate 46. Manually operated start button 50 produces a pulse from monostable 48 which enables gate 46 for a period sufficient to allow the passage of only one spike from differentiator 44. This spike triggers monostable 52 which produces on output for just less than two frame periods which output is fed to gate 32. The gate output J which represents the amount of a frame period that the signal is "black" enables AND gate 64 Fig. 5 gating high frequency pulses from oscillator 60 via variable divider 66 to counter 62 with NIXIE read-out 68. The divider is variable under control of divider control 70, the division factor being indicated at 72. In operation a test card with known black area is used. This area in desired units is set up in divider 66 and a reading is taken. The value in counter 62 is then set into divider 66 and subsequent readings are then in the correct units. For measuring length, a differentiator and monostable may be interposed between trigger 56 and gate 32. The scaling means may also be a multiplier or multiplier/divider combination or the frequency of oscillator 60 may be varied. Readings may be made over a different number of frame periods.

Title: Apparatus and method for examining a blood vessel of interest using radiation detected outside the body
IPC: G06F19/00
Filed: 1978-09-23
Abstract: Particulate sources of signals which can be detected outside the body of a patient are introduced into the circulating blood and are tracked in three dimensions in the region of the heart using suitable detectors (7, 7', 8, 8') disposed about the patient's chest. This permits the sequence of positions of each particle to be recorded as a function of time as each particle flows through a coronary vessel. Data analyses of these recordings of particle positions provide information about the velocity of blood flow through, and the course of each coronary artery. This velocity information is used to determine the extent, severity and location of stenotic lesions of the coronary arteries. The sources preferably contain a positron emitter and their position is determined from produced pairs of  gamma  rays. <IMAGE>

Patent GB-787174-A (GB)
Abstract: 787,174. Cash registers. NATIONAL CASH REGISTER CO. Sept. 4, 1956 [Sept. 9, 1955], No. 26974/56. Class 106 (1). Mechanism for shifting the record strip 20, Fig. 1, between reading and printing positions comprises a pair of spaced guides for the strip, e.g. the rollers 40 and 41, a pinion 45 fast with a pivoted carrier for these guides and a cyclically-reciprocated rack 48 for driving the pinion to rock the carrier. The guides or rollers 40 and 41 are normally so disposed that the section of strip between them extends substantially transversely to the direction of feed, the latest entries then lying beneath a window 21 and autographic writing aperture 24. During machine operation, the rack 48 moves downwardly, the pinion 45 and carrier are turned clockwise and the strip is fed upwardly, under tension constantly applied to the supply spool 25, to bring the strip into printing position opposite the type wheels 29. In the particular mechanism shown, the rack 48 is pin-and-slot connected to the spring- actuated follower 50 of a cam 56. This cam is one of an assembly of three cyclicallyactuated cams including also a cam 65 for operating the printing hammer and a cam 33 for line-spacing the strip by means of the receiving roll 31. Control of record strip printing. The cam assembly is driven through a clutch comprising a notched driving member 68, Fig. 2, fast with a gear 69 adapted to be driven one revolution counterclockwise during each machine operation. The driven element of the clutch comprises a plate 66 fast with the cam assembly and bearing a spring-actuated dog 71 normally engaged with the notch of the driving member 68. A control arm 101 for the clutch is pivoted at 102 and carries a roller 100 bearing against a cam 70 fast with the gear 69, the cam allowing the arm to move inwardly under spring tension early in each cycle. Movement of the arm 101 is under the control of a notched disc 78 adapted to be differentially adjusted according to which key of a bank of control keys 73 to 77 has been depressed. In the case of the keys 74 and 75 (Subtotal and Multiple-Item), a notch 107 in the disc 78 clears an ear 104 of the control arm 101 allowing the arm to move inwardly. An ear 105 on the arm then trips the dog 71, the drive is not transmitted to the cam assembly and the record strip mechanism is not operated. The other keys position the disc 78 to obstruct inward movement of the aim 101, so that the clutch dog 71 is not tripped and the record strip mechanism is operated. The arm 101 is also under the control of a second bank of control keys which is adapted to position a stop arm (not shown) differentially, the stop arm engaging under a further ear 122 on the arm 101 when moved to certain positions. The record strip mechanism then operates even when the keys 74 and 75 of the first bank also are depressed.

Filed: 1979-06-12
Abstract: An interval timer adapted for the repetitive timing of at least two, but preferably three, pre-set time intervals - typically of 15, 30 and 60 seconds. The timer includes an electronic circuit (Figure 3) adapted to produce distinct audible and/or visual alarm signals at the completion of each pre-set time interval following initiation of a timing cycle. The timer includes an electronic circuit (Fig. 3) operating on a digital basis having a first multivibrator (gates 30 and 31) feeding pulses to a ripple counter 37. Outputs for the required time intervals are taken from the counter to enable a multivibrator (gates 53 and 54) which drives an alarm output device 59. A reset switch 20 serves to reset the counter 37 and at the completion of a timing cycle, the multivibrator (gates 30 and 31) is rendered inoperative until the reset switch is depressed again. An alarm may be sounded or an LED flashed to warn of insufficient battery voltage. <IMAGE>
