Abstract: 875,027. Couplings between relatively movable conducting parts; neutralizing thermal expansion in electric couplings. BRITISH INSULATED CALLENDER'S CABLES Ltd. April 21, 1960 [April 21, 1959], No. 13578/59. Class 38 (1). An overhead electric conductor system comprises three conductors 1 located within a flexible tube 2 having a longitudinal slit 3 and formed of extruded polychloroprene, clamps being secured along the length of the tube. Each clamp consists of an internal member 4 and an external member 5 held together by a screw 6 passing through the tube 2. The internal members 4 are of epoxy resin and have grooves on their inner faces to receive the bull-headed conductor rails 1. Additional grooves 11 increase the creepage path between neighbouring conductors. The external members 5 are provided with clamping means 14, 16 for engaging catenary wires 13 which are given additional support by bridges 17 secured to a fixed support 18. When the system is of considerable length, connectors 21 are used to joint successive lengths and such connectors, one on each side of an internal clamping member 4, may be used to locate the conductors endwise. In a modification, Fig. 2, thermal expansion joints for the conductors each consist of a connector 23 clamped to one conductor end only, the other conductor being free to slide in the connector 23 and having a second connector 25 clamped to it. A looped flexible lead 27 is cast or sweated to the two connectors. Fig. 2 also shows a collector of which a table 28 of insulating material is supported by a spring- loaded trolley arm 29 mounted on a carriage (not shown) which travels along a path parallel to the conductor system. The lower parts of lateral walls 31 formed on the table engage parts of the walls of the tube 2 on each side of the slit 3 and open the tube to the extent required. Lateral guidance for the collector is provided by the deflected parts of the tube wall, by engagement of the tube wall with upwardlyprojecting wall 30 of the collector, and by the walls 32 on the collector which register with the centre conductor. Spring - loaded carbon brushes 33 bear on the lower face of the conductors. Alternatively, the brushes may be of metal and spring-urged or they may be of spring form. An earth or neutral conductor may be provided externally of the flexible tube, Fig. 3 (not shown). Specification 774,558 is referred to.

Title: Digital processor having automatic conflict-resolving logic
IPC: G06F9/48
Filed: 1971-05-07
Abstract: 1354377 Digital computers; interrupt INCOTERM CORP 7 May 1971 [10 June 1970] 13795/71 Heading G4A A digital data processor has an executive operation which can resolve interrupt situations. The processor is connected to a number of asynchronously operated I/O devices 11 and an interrupt can arise if data is to be transferred between them and either the processor or the device is not ready, or if an interrupt arises due to a request for service. The processor is normally executing instructions (instruction state) but, when an interrupt occurs, it switches to an automatic instruction operation which is stated to be economical in memory space. Operation (Fig. 2, not shown).-When the processor is in the instruction state the processor reads an instruction from core memory 12 and passes the instruction to register 16 and its opcode to register 18. It then senses if the instruction is concerned with reading or writing of data with an I/O device 11 (an I/O instruction). If not, and if there are no interrupts pending, the instruction is executed and the next instruction fetched. If it is an I/O instruction, the processor transmits a request for service to the I/O device and, if an acknowledgement is received within a certain time, the instruction is completed. If one is not received in that time the processor loads into register 14, from special address generator 48, an address in memory 12 of a location reserved for that I/O device (an autoexecutive (A-E) device address) and the processor goes into an extension W state. The processor stores its present status in the A-E address location, increments the address in register 14 to the A-E address, switches to an extension X state then loads a background address, switches to an extension Y state and operates on a background instruction sequence using data in the background location. There is a similar routine if there is an interrupt pending during execution of a normal instruction. Here the processor status is stored in the background location and the processor status for handling the interrupt is loaded from the A-E address location. The interrupt operations are controlled by a sequence control logic unit (Fig. 3, not shown).

[Also in Division F2] A method for interconnecting two steel bars 1, 2 which have raised portions extending at an angle to the axis of the bars, comprises the steps of disposing over the adjacent ends of the bars 1, 2 an annular sleeve 8 having a full length opening therein and compressing the sleeve around the ends of the bars by subjecting the sleeve to a cold flow process by means of compression jaws movable transversely of the axial direction of the sleeve. The inner surface of the sleeve is shaped before compression, or the outer surface of the sleeve is shaped during compression so that the inner surface of the sleeve co-operates with the raised portions of the bar ends to produce axial forces acting to push the bar ends together. The internal surface of the sleeve may be provided with internal corrugations or toothings 9 which on being urged on to the surface of the bars 1, 2 cause the bars to be forced towards each other. The cold flow process is effected by the compression jaws of the press (Figs. 2, 3, not shown) in one or more pressing stages. The sleeve may also be heated before the cold flow process. The sleeve material has a wall thickness similar to the thickness of the bars and may be of steel or aluminium or an aluminium alloy.

Title: Improvements in or relating to grain-cleaning or-treating machines

Abstract: 475,506. Cleaning &c. grain. SIMON, Ltd., H., LOCKWOOD, J. F., and WATTS, G. May 19, 1936, No. 14193. [Class 58] A grain cleaning or treating machine in which dust or light particles are removed from the grain comprises a cylindrical casing 10 into which the grain is fed by a conduit 12 and in which it is operated upon by a helical brush 11 which carries it to an opening at the other end of the casing through which it passes to a shoot 13 communicating with an air-box 14. The casing is divided by a vertical transverse partition 9 which also extends across a compartment 15 above the casing 10 this compartment being provided with an air circulator 16 and a cyclone separator 17. The air circulator 16 comprises an air impeller provided with two rotors 18, 19, the rotor 18 communicating through a control inlet with an air-box 20 opening on both sides of the partition 9 ; a conduit 21 leads from the periphery of the rotor 18 to the separator 17. The shoot 13 has an outlet slit 31 which causes the grain to fall in a thin sheet across a current of air which is drawn from the box 14 up a channel 32 to the compartment 15 where the heavy dust is deposited in a trough 34 from which it is ejected by a conveyer 35. The air and light dust pass through an opening 36 in the partition 9 to the box 20 and thence to the rotor 18. The rotor 19 forces air through a conduit 22 to the air box 14 or through a branch passage 23 to the cylindrical casing 10 whence it escapes through a slot 24 to the casing 15. The air laden with dust particles concentrates at the periphery of the rotor 18 and passes from these through the passage 21 to the separator 17 leaving comparatively dust free air to be forced by the rotor 19 into the grain treating chamber. Purified air from the separator 17 is directed through a tube 25 to the casing 10. The accumulated dust from the separator falls through a shoot 27 into a trough 28 whence a conveyer discharges it through the side of the casing.
