Title: Display panel electrode termination
IPC: H01R12/70
Filed: 1972-11-13
Abstract: 1389545 Alpha numeric displays BURROUGHS CORP 13 Nov 1972 [24 Nov 1971] 52256/72 Heading G5C [Also in Divisions H1 and H2] Electrodes seated on the opposed inner surfaces of spaced insulating plates 20 and 100 of a display device 10 are connected to terminals 35 and 140 also disposed on said inner surfaces and accessible to connecting means 228 inverted between the plates. The display device shown is a gas-filled panel in which groups of cathode segments are deposited on the base plate 20 and corresponding segments in the groups are connected in common to a terminal 35. An anode for each group of cathodes is deposited on the face plate 100 and has a connecting tab 140. The insulating spacer 110 is a frame with ribs separating the groups of cathode segments and may incorporate a metal layer (Fig. 1, not shown), the connectors 225 comprise spaced resilient strip portions 226 and 227 so that each connector can engage either an anode tab 140 or a cathode terminal 35. Tails 220 of the connectors may be bent and inserted into apertures 310 in a printed circuit board 300 and soldered to conductive runs 320. The device 10 may thus be supported at any desired angle. Bending stress on the connectors may be relieved by a housing 260. An alternative housing (Fig. 6, not shown), providing an alternative means of supporting the display device has a lug with a hole for a bolt. This housing also has slots in which tabs projecting from the metal layer of the spacer 110 are secured by set screws thus securing the connectors to the display device and providing a connection to the metal layer, e.g. for applying a bias potential. The gas filling may be neon, argon and/or zenon with mercury vapour, the pressure being from 20 to 250 torr with 70 to 120 torr preferred. The display device may alternatively utilize liquid crystal material, various suspensions or emulsions, or semi-conductor or luminescent material between energizing electrodes.

Abstract: 1,209,144. Refrigerating. DISTILLERS CO. (CARBON DIOXIDE) Ltd. 21 Feb., 1968 [25 Nov., 1966], No. 52795/66. Heading F4H. Apparatus for freezing liquid in a pipe-line comprises a source of liquefied refrigerant gas, an expansion and cooling zone in which the pipe-line can be located, a tube of relatively small cross-section for supplying liquefied gas to the zone and a tube of relatively large cross-section for removing refrigerant vapour from the zone. As shown in Fig. 2, a tube 22 has a screw 26 for connection to a liquefied gas cylinder and comprises a filter 27 and inlet chamber 28 for the liquefied gas, and a plug 29 into which one end of a tube 20 is soldered, the flow of liquid into tube 20 being limited by a pre-set valve 30. An externally adjustable valve may alternatively be employed. Tube 20 extends coaxially within a tube 21, which is connected at one end to tube 22 and at the other end to an expansion chamber 40 (Fig. 3), and terminates within chamber 40. The latter is shaped at 41 to receive a pipe 9, which is to be blocked by freezing, and has a cover 42. Gas from chamber 40 returns via tubes 21 and 22 to a tube 7 which leads to a device in which the gas is burnt in admixture with atmospheric air (Fig. 1, not shown). Tube 21 is made of nylon and tube 20 of stainless steel. A stand is provided for the liquefied gas container. In a modification (Fig. 5, not shown), the expansion chamber is of part-annular form and is defined by the pipe to be cooled and a synthetic rubber casing which is preformed to seal around the pipe or is clamped therearound. A tube is provided for conveying gases leaking from the expansion chamber to the burner.

Title: Systems for the automatic reading of information
IPC: B61L25/04
Filed: 1967-11-21
Abstract: 1,208,141. Vehicle identity. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. 21 Nov., 1967 [22 Nov., 1966; 3 Feb., 1967], No. 53021/67. Heading B7N. In a system for automatically reading information carried by moving objects or vehicles, e.g. a rail vehicle, the vehicle carries a plate perforated in accordance with the information which is scanned in passing by light, X-ray or gamma-ray radiation from a traokside source and the radiation transmitted by the plate energizes detectors also disposed adjacent the track. One example of plate is shown in Fig. 8 and includes an upper row 52 perforated in accordance with the information, a lower row 84 perforated in accordance with its complement and a middle row 83 regularly perforated to provide synchronizing and reference signals. The information is coded in decimal binary form and the left and right hand sides of the plate GAU and DRO are perforated to provide start and finish signals or vice-versa depending on the direction of movement of the plate. Four detectors are provided, sync. detector 1 and reference detector 2 co-operate with the middle row and information detectors 3 and 4 co-operate respectively with the upper and lower rows. Detector 1 is associated with a signal generator 5 which supplies a positive signal DS at terminal 18 when the detector is illuminated and a similar signal DS at terminal 19 when the detector is not illuminated, similarly detectors 2-4 provide signals DR, DR; D1, D1 and D2, D2 at terminals 20-25. The reference and information signals are applied with signals T+ and T-, representing transitions in the sync. signal DS, to a start and finish correlator 10 which supplies start D + or D- and finish F+ or F- signals (+ or - depending on the direction of motion) to a programmer 12 which supplies a read signal L to synchronization member 9 and information correlator 11. The sync. member 9 supplies pulses S+ or S-, derived from transitions in signals DR and + or - in dependence on the direction of movement, to a reversible counter 13 having a capacity N equal to the number of binary digits. The. counter .via a matrix 14 and address member 15 prepares in turn the N elements of a memory 16 to receive the information signals Io (binary 0) and I1 (binary 1) from information correlator 11 in which the information signals are sampled by pulse train TŒ. The information read into the memory 'is transferred to a register 17 from which it is transferred to a utilization device on receipt of finish signal TR from programmer 12. The reversible counter allows the plate to be read in either direction and also allows the plate to be read should the vehicle stop, reverse, then restart in the original direction during the reading process. Error signals delivered respectively by the information correlator 11 (EC), the memory 16 (EM) and the programmer 12 (EP) are connected to OR gate 18 which supplies an output to return the counter, the memory and the programmer to zero.

As shown the arm 42 carries rack 54 slidably mounted therein and the end of the rack is connected by a bracket 60 and a pivot pin 62 to the second arm 40. A rack 70 is movable in slidewarp 74 in arm 40 under control of a motor 30 and at its end supports a clamp 52 on a carrier 76. The clamp 52 may have a single plate with a high friction under surface 94 which holds the workpiece against the worktable 20 and moves it thereon. Alternatively the clamp may have a second plate below the high friction surface, the workpiece being clamped between the two. A pulse generator is connected to the main needle drive shaft of the machine and produces 1000 pulses for each revolution of the needle drive shaft. These pulses are fed into a digital computer which divides the stitch cycle up into a dwell period, during which the needle forms a stitch with the workpiece stationary, an acceleration drive and decelleration period during which the motors cause the arms to move the work clamp and subsequently a second dwell period. The driving period is further split up by the computer to determine the extent of movement required by each motor to bring the workpiece into the next desired position along the predetermined path at the correct distance commensurate with the required stitch length. It is stated that a third arm and suitable driving motor may be provided in the apparatus so that a general motion in three dimensions for a tool holder is obtained.
