Abstract: 1,053,327. Electrophotographic processes. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug.24, 1964 [Aug. 23, 1963], No.34588/64. Heading G2H. In an electrostatic image transfer step in which image bearing and image receiving dielectric surfaces are sandwiched together between conducting elements at the same electrical potential, the interfacial pressure is made sufficiently great to exclude substantially all traces of air from the interface. A potential opposing charge transfer may initially be applied to the interface, until the high pressure of several hundred p. s. i. has been established. As shown, a metal drum 10', coated with a layer 14' of amorphous selenium, is conventionally charged at 48 and exposed by means of projection lens 47. A web 20' of dielectric material which may be "Mylar" (Registered Trade Mark), polystyrene, polyethylene as a styrene butadiene copolymer is wound over guide rollers between reels 54 and 56. A conductive roller 22 brings the web 20' into contact with layer 14' and is electrically connected to a source of potential opposing transfer. The resilient conducting outer surface layer of roller 32 provides a conducting pressure element at the same potential as metal drum 10' and is hydraulically urged to effect transfer. Developer powder for the transferred image is applied by hopper 82 to a pile fabric roller 84 and to a velvet covered roller 86. The developed image is fixed by heating at 92. In another form Fig. 10, (not shown), a semi-transparent photoconductive layer of polyvinyl carbazole or zinc oxide in a resin binder is carried on an endless belt of "Mylar" (Registered Trade Mark), a transparent conductive layer of evaporated gold being interposed between the photo-conductive layer and carrier. Exposure is made by reflex contact-printing and the electrostatic image is transferred on to a sheet of electrographic paper, consisting of a layer of polythene on a conductive paper base, by means of a hydraulically operated roller. The transferred image is developed by the application of a liquid by a porous roller connected to a bias potential supply.

Abstract: 1,231,188. Printing surfaces. STRACHAN & HENSHAW Ltd. 6 Nov., 1968 [8 Nov., 1967], No. 50745/67. Heading B6C. An assembly 4<SP>1</SP> for locking up a flexible printing plate 36 on a cylinder comprises two jaw members 12, 39 separated by a slit 9 for the insertion of two internal end flanges 37, 38 on the plate, and resilient member 15<SP>1</SP> attached to one of the jaw members and situated between the jaw members, one of the jaws being normally fixed relative to the cylinder and the other jaw being releasable so that it is resiliently urged towards the other jaw to cause the end flanges of the plate to be gripped between the jaws and the resilient member. In one construction, Fig. 1 (not shown), the normally fixed jaw is secured directly to the cylinder, but as shown in Figs. 4, 5 it may be given a circumferential movement or a skew movement to adjust the register of the plate. The assembly comprises two filler blocks 6, 7<SP>1</SP> mounted in a recess 3<SP>1</SP> in the cylinder. A normally-fixed jaw 39 is secured to the block 7<SP>1</SP> and a jaw 12 is as shown pivoted at 20 to the block 6 but it may be slidably mounted. Springs 24 urge the jaw 12 towards the jaw 39, but arms 30 on the jaw 12 engage a shaft 32 to prevent movement of the jaw 12 unless the shaft 32 is rotated to present flats thereon to the arms 30. The tips of the jaws are separated by a slit 9. To the jaw 39 is fixed a resilient member 15<SP>1</SP> and, before locking up, the inturned flanges 37, 38 are inserted respectively between the jaws 12, 39 and the member 15<SP>1</SP>. The jaw 12 is now released by rotating the shaft 32 so that under the action of the springs 24 it moves towards the jaw 39 so that the flanges 37, 38 are gripped respectively between the parts 39, 15<SP>1</SP> and 12, 15<SP>1</SP> without the flanges contacting one another, the plate 36 being tensioned at the same time. The holes in bearing blocks 21<SP>1</SP> carrying the pivot 20 are over-size so that the jaw 12 can move to accommodate inaccuracies in the plate flange. The jaw 12 may be axially divided to take care of such inaccuracies or a number of separate assemblies 41 may be disposed axially side by side. In the latter case, the flats on shaft 32 associated with each assembly may be staggered so that the operation of the various assemblies may take place at different stages of the rotation of the shaft. For registering the plate 36, the jaw 39 may be adjusted as referred to above. For this purpose, the jaw has two lugs 60, Fig. 5, carrying screws 50 having non-threaded parts 52 engaging slots 54 in wedge members 55 engaging correspondingly-angled faces 59 on the jaw 39. The members 55 are engaged by oppositely-threaded parts 56, 57 on a shaft 43 rotation of which causes circumferential movement of the jaw 39 which movement is followed by the jaw 12 under the action of the springs 24. A block 41 fixed axially relatively to the shaft 43 can be moved by rotation of a threaded rod 42 so as to move the shaft 43 and blocks 55, thus causing a skewing movement of the jaw 39 and plate 36.

As shown in Fig. 2, the ring 5 is of L-cross-section with its axial arm located in a recess formed in the land 10 and a projection on the free end of the arm, formed as by rolling, engaging a groove 6 in the land. A tongue 8 on the ring engages a groove 7 in the ring groove wall. In a modification, Fig. 4, the outer edge of the ring 5 is secured both axially and radially by the projection on the ring which engages the groove 13 being of L-cross-section. In a further modification, Fig. 5 (not shown), the wear ring (5) is of rectangular cross-section and is secured at its outer edge to the groove wall by soldering (16). The wear ring may be clamped against the groove wall whilst the rolling over or soldering operation is performed by a tool 11, Fig. 2, or a roller chain and turnbuckle 11a, Fig. 4. The working surface of the ring 5 may be coated with molybdenum or chromium 12, Fig. 2, and the surface abutting the groove wall may be coated with a malleable material, e.g. copper or lead, to facilitate heat transfer.

Abstract: 1,239,168. Radar. TOKYO KEIKI K.K. 4 Aug., 1969 [8 Aug., 1968], No. 38898/69. Heading H4D. [Also in Division H2] In a system in which a first shaft is driven by means which also drive a generator, and a second shaft is driven by means synchronously with the generator, to achieve initial angular alignment between the shafts there are first and second switches associated with the respective shafts which control third and fourth switches to interrupt the current to the synchronous drive of the second shaft and apply direct current braking thereto, the arrangement being that the second shaft is stopped at a datum point until the first shaft reaches a corresponding point. As shown, deflection coils 6 of a radar P.P.I. are rotated by a shaft 8 driven via a gear-box 24 by a synchronous motor 22 which is energized by a generator 13 driven by a motor 4 which also drives, via a gear-box 3, a shaft 2 which rotates an aerial 1. Switches 11, 12 operated by cams 9, 10 coupled to the shafts 2, 8 control a relay logic circuit 25 which controls change-over switches 17a, 17b between the generator 13 and motor 22. Initially, 17a and 17b are as shown, and the motor 22 rotates synchronously with generator 13, but out of phase. When receiver cam 10 operates switch 12, 17a and 17b change over, connecting charged capacitors 18a, 18b and a D.C. source 19 to the motor 22, thereby braking and holding it, until transmitter cam 9 operates switch 11, whereupon switches 17a and 1 7b revert and rotation of 22 is resumed, this time with the shaft 8 in phase with shaft 2. The logic circuit 25 is described, with three alternatives (Figs. 2 . . . 5, not shown). In an alternative embodiment (Fig. 6, not shown), control is effected as in the embodiment shown, but the logic circuit 25 is replaced by transistor bi-stable and switching circuits which it is explained give more accurate phase synchronization.

Abstract: 1,258,841. Measuring heat transfer. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Dec., 1969 [6 Dec., 1968], No. 59273/69. Heading G4H. In a method of measuring the heat dissipated by a heat exchanger the amount of fluid flowing through the exchanger is measured by impeller 4, and the temperature difference across the exchanger is measured by temperature sensors 6 and 7. A series of pulses whose number is proportionalto the amount of fluid flowing through the exchanger is produced by pick up 5. Pulse duration modulator 9 alters the pulse duration so that the pulse duration of each pulse is proportional to the temperature difference across the heat exchanger. These pulses whose total duration (i.e. duration of each pulse x number of pulses) is proportional to the heat dissipated by the heat exchanger operate gate 11 to pass A.C. signals only during a pulse. Counter 12 counts the total number of A.C. cycles passed by gate 11, the count thus indicated by indicator 13 is a measure of the heat dissipated by the heat exchanger.
