Title: Beam Deflection Circuit
IPC: G09G1/10
Filed: 1967-12-19
Abstract: 1,162,289. Cathode-ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORP. 19 Dec., 1967 [27 Dec., 1966], No. 57739/67. Heading H4T. An electromagnetic beam deflection circuit for a cathode-ray tube comprises two groups of sources of deflection current the sources of one group each supplying a different magnitude of current and those of the other group each supplying an equal magnitude of current greater than the total current supplied by the first group. This arrangement avoids deflection errors which arise when the currents are supplied by binary weighted sources with one source providing one half the total current for full scale deflection whilst another source merely provides current for a single unit of deflection since the effect of, e.g., 1% error in the sources causes an absolute error in the larger source which is greater than the total current supplied by the smallest source. Fig. 1 shows one arrangement in which, for deflection in the X directions (the Y deflection circuitry being similar), binary weighted current sources I1, I2, 14 and I8 are connected via switches S1-S4 and amplifiers 14, 16 to the X, X deflection coils, the switches being controlled by a binary counter 12 incremented by an oscillator 10. When counter 12 is re-set to zero a pulse is supplied to a digital counter 18 which, on each resetting of counter 12, supplies equal current steps to one of the amplifiers 14 or 16 depending on whether a stage of the counter 18 is set to a " zero " or to a " one " state the current steps being equal to the sum of the currents from the binary weighted sources plus the magnitude of the current from the source of smallest magnitude, i.e. each current step = 2I1 + I2 + I4 + I8. Fig. 3 shows an arrangement for generating computer controlled graphic displays in which the lower order bits, e.g. N=3, are supplied, from a computer 30, to a binary register 3 whilst the remaining high order bits are supplied via an encoder 38 (detailed in Fig. 4, not shown), which supplies an output in decimal form, to a register 40, the various stages of which control equal current steps, the magnitude of the step being determined as described above for the Fig. 1 arrangement. The outputs of the various stages of register 32 are then converted to analogue current steps in 33 and these together with the current steps from register 40 are utilized in similar manner as described for the Fig. 1 arrangement.

Title: Film pack
IPC: G03B17/34
Filed: 1968-12-18
Abstract: 1,255,616. Film packs. AGFA-GEVAERT A. G. Dec,18, 1968 [Dec. 22, 1967; Aug. 14, 1968], No. 60205/68. Heading G2A. In a film pack for use in self-developing cameras and comprising at least two film sections each having a photo-sensitive sheet 5 and an image transfer sheet 9, the trailing end of sheet 5 is connected by a flexible strip 14 to the pull-out tab 7 of the following film section. As shown, the film pack is a cassette housing 1, with an exposure aperture 1a in its upper surface, and an opening 1b through which the sheets are withdrawn to pass between pressure rollers 10, 11. A flexible wall 2 divides an upper chamber for a stack of sheets 5, and a lower chamber for a stack of sheets 9. The two sheets are connected to pullout tab 7 by intermediate sections 6, 3, section 6 carrying the sac 12 of developer material. The connecting strip 14 runs from the trailing end of sheet 5 and is guided round the sheet sections to the tab 7 of the following section, where it widens out to a gripping piece 16. At one end of piece 16 is a thickened part 15, and a line of perforations 17 across strip 14. Thus when the strip is pulled between rollers 10, 11, the thickened part 15 offers resistance as it comes up against the rollers, and hence the strip tears along the perforations. The piece 16 of the following film section is then in the withdrawal position. A number of further separate strips 14a-14c are provided as shown, to prevent sheet 5 being distorted out of the flat in the exposure position. A new film pack may have an initial pull strip (18), Fig. 3 (not shown) attached to a light-impermeable sheet. Fig. 4 (not shown) is a modification in which the thickened part 15 is obliquely arranged and extends over only part of the width of the strip. In a further modification Fig. 5 (not shown) the strip 14 is bifurcated, and lies only along the extreme edges of the sheet 5 in order not to affect the light-sensitive coating thereon,

Title: Control arrangement for ac motors
IPC: H02P5/74
Filed: 1978-07-12
Abstract: For supplying groups (1, 2, 3, 4) of synchronous motors, preferably hysteresis motors, alternating current is supplied from an AC power supply (19) to a controllable AC/DC converter (10). The output of the converter (10) is connected via an intermediate circuit (12) having power storage means to a DC/AC converter (8), whose output supplies the motor groups (1, 2, 3, 4). Reactive power compensating means (7) are also connected to converter (8) whose frequency is determined by signal uf applied to control unit (18). Control means (20, 21 and 17 or 27 to 32) control the voltage V1 of converter (10) in accordance with a control signal us and an additional signal uz superimposed on the signal us, the signal uz being proportional to the current in the intermediate circuit (12) and hence to the amplitude of the "intermediate circuit oscillation," which is of low frequency relative to the operating frequency of converter (8) and is produced by self-excitation in the system comprising the motor groups (1-4), capacitors (7) and the circuit (12). The oscillation occurs mainly during simultaneous run-up of the motor groups just before they enter into synchronism and leads to cycling between synchronous and asynchronous operation and unstable operation of the converter. The oscillation is reduced or eliminated by the signal uz whose effect is equivalent to adding a stabilising resistor to the circuit (12). <IMAGE>

Title: Improvements in Circular Knitting Machines
IPC: B65H51/14
Filed: 1978-09-08
Abstract: To furnish a knitting point in a circular knitting machine with a yarn consisting of two or more component yarns twisted about each other, component yarns withdrawn from at least two individual coils or packages are, during their transit from said coils to the knitting point, subjected to the action of a twisting tool the rotation of which is reversed periodically. To prevent or reduce untwisting of the yarn caused by equalization between yarn portions having opposed twists, the yarn leaving the twisting tool is gripped by gripping members e.g. pads 35 on belts 34 which travel with the yarn or by moving belts whose whole surface is covered with foam rubber. If the twisting tool is placed sufficiently close to the knitting point, no other gripping members than the needles of the knitting machines are required. <IMAGE>

Title: Fruit handling and cleaning
IPC: A23N12/02
Filed: 1979-06-25
Abstract: An apparatus for cleaning berries includes a separator which receives berries and waste material entrained in water and separates the berries from the waste material by causing the entraining water to flow over a number of surfaces which have corners. The relatively light waste material is carried around the corners by the water whereas the relatively heavy berries pass straight on. The separator comprises a vertical array 60 of U- shaped channel members, the bottoms of the U's being upwardly inclined so that water with the entrained waste and berries is incident upon them. Before reaching the separator the berries are first broken up into individual berries by means of a loosening unit 30 and adhered waste material is detached from the berries in a washing unit 50. After passing through the separator the berries are dried in a continuous centrifuge 70. <IMAGE>
