Patent GB-2136378-A (GB)
Title: Mine conveyors
Inventor: NELSON JAMES
IPC: B65G19/28
Filed: 1983-02-03
Abstract: A mine conveyor comprises a series of pans connected together by linkages which allow pivoting in a horizontal plane to permit snaking-over of the conveyor, said linkages consisting of a single ball-joint 2 between adjacent pans on one side and at least one loose joint 3 on the other side which permits substantially greater freedom of movement than the ball-joint. In another embodiment the mine conveyor comprises a series of line pans connected together on one side by hinge joints which permit pivoting between adjacent pans about a vertical axis but only limited movement about a horizontal axis and a trapped joint on the other side enabling the joint to be connected by hooking a male end projecting from one pan into a recess in the other. <IMAGE>

Title: Load supporting vehicle suspension beams
Inventor: HARLE CHRISTOPHER NORTON
IPC: E04C3/06
Filed: 1983-05-24
Abstract: The invention relates to load bearing beams, and has for its object the provision of such beam of high strength and hence high load carrying capacity with relatively low weight, such as would be suitable for use in vehicles. The objective is met by a construction comprising a beam-like member formed by two spaced plate-like members, each of which has an outwardly directed flange to one side and an inwardly directed flange to the other side, to be of generally Z-shaped cross-section, said two plate-like members being secured to and spaced by internal cross-members. Thus, with the outwardly and inwardly directed flanges respectively being to the same side of the plate-like members an effective box-like structure is formed within which lie the spacing internal cross-members.

Title: Actuating a back-pedalling brake in a bicycle driving assembly
Inventor: BERGLES EDUARD
IPC: B62L5/00
Filed: 1983-08-02
Abstract: In a bicycle a rear wheel hub 1 is driven by a chain from a pedal shaft and includes a clutch-brake combination 3,4,5. The chain is shifted to various rear wheel sprockets 6 to change the transmission ratio. A chain tensioner compensates for the differences in diameter of the various sprockets. To avoid loosening of the upper chain strand and belated brake effect in response to backward pedaling, a separate brake- actuating transmission line is provided between the pedal shaft and a driver member 2 of the rear wheel hub. This transmission line comprises a free- wheel unit mounted onto the pedal shaft and a disengageable drive unit 8 adjacent the rear wheel hub. The units are interconnected by a transmission member 12 separate from the chain. The disengageable drive unit 8 may comprise a pinion 7 fixed to the driver member 2 and a rack 9 formed by a series of pins 10 engageable with the pinion 7 on displacement of the rack 9 in direction F. <IMAGE>

Patent GB-2158326-A (GB)
Title: Testing arrangements of a digital switching systems
Inventor: MURRAY JAMES ANDREW
IPC: H04Q11/04
Filed: 1984-04-26
Abstract: To test a digital line from a switching centre to subscriber's apparatus a loopback test method is used, in which a pseudo-random bit sequence is sent from the exchange via the GO path and looped back at a desired one of three points (A, B, C) in the path. After each loopback the bit sequence as it returns is monitored and its condition indicates whether there is an error present. By successive use of the different loopback points a detected error can be located.   Generation of the pseudo-random bit sequence uses a feedback shift register, and monitoring is effected by applying the returned bit sequence to a similar feedback shift register whose condition thereafter indicates whether there is an error present. The output of the second register is used, with a counter to so control a third feedback shift register to eliminate errors due to the taps on the second register. <IMAGE>
