Title: Improvements in the testing of electric cables
IPC: G01R31/02
Filed: 1978-09-08
Abstract: The invention relates to the manufacture of cables, and is of particular utility in the manufacture of coaxial cables. To measure the consistency of the thickness of an extruded dielectric material (14) over the central conductor (10) of a part-formed coaxial cable (16), the cable is passed between capacitance plates (22, 24) optionally in a water bath (18). The capacitance between the plates is measured by network (30), and the reactive component of the output is recorded in a recorder (52). The recorder is periodically replayed at a higher speed and the frequency spectrum analysed and displayed on an oscilloscope (58). If the part- formed cable is satisfactory, the outer conductor can then be added. <IMAGE>

Patent GB-2057996-A (GB)
Title: Walking beam conveyor
IPC: B65G25/02
Filed: 1979-09-07
Abstract: A walking beam conveyor comprises a walking beam 12 which is movable along a closed path with respect to a fixed part 13 of the conveyor. As the beam is raised with respect to the fixed part it lifts objects to be transported from the fixed part, moves forward and deposits them again on the fixed part of the conveyor. If the objects are relatively large compared with the width of the beam or if the objects are relatively unstable then they may fall off the beam. To avoid this from happening it is proposed to provide the walking beam with transverse arms 17 which serve to support the objects to be transported even when those objects are decentralised relative to the beam. The upper faces of the arms may have U-sections to support cylindrical objects with their axes horizontal. <IMAGE>
Patent GB-2030680-A (GB)
Title: Spline drive arrangement
IPC: F16D3/06
Filed: 1979-09-07
Abstract: A spline drive arrangement has two externally-splined shafts 10, 12 which engage an internally-splined gear 14. An extension 15 on the shaft 10 is a relatively close fit in a bush 17 which lines a bore 16 in the shaft 12. The drive arrangement is maintained full of a liquid which can enter and leave a space 18 in the bore 16 by way of restricted passages 19, 20 and a clearance zone between the extension 15 and bush 17. Damping and viscous drag of the liquid tends to prevent relative movement between the splines of the shaft 12 and gear 14, which may occur if the torque load on the shaft 12 is low, and also to prevent relative axial movement between shaft 12 and shaft 10. <IMAGE>
Patent GB-2036376-A (GB)
Title: Robot System
IPC: G05B19/423
Filed: 1979-09-21
Abstract: A programming device 23 is attached to a motor driven robot arm 22 for recording the robot movements along a predetermined spatial track in a teaching mode. The recorded data enables the robot movements to be repeated in a playback mode. The device includes a centre portion rigidly attached to the robot arm and a sleeve surrounding the centre portion. Separate, flexible blades join the sleeve and centre portion to each other, with a separate strain gauge transducer fixedly attached to each flexible blade which detects bending forces employed to move the sleeve and robot. The transducers generate output signals indicative of the magnitude and direction of the forces, which signals are used for deducing the movements. <IMAGE>
Patent GB-2035489-A (GB)
Title: Deceleration-responsive brake controls
IPC: B60T8/74
Filed: 1979-10-09
Abstract: A rail vehicle emergency braking system produces a braking effort which lies in a range (because of operating variables) which extends beyond that giving the maximum allowable deceleration. A deceleration responsive switch, e.g. a mercury switch, however modifies the brake control input when a certain deceleration is reached, so that the maximum is not in fact exceeded. A control valve has a supply port 23, or brake port 22, and a control pressure port 21. Brake pressure acts on the underside of diaphragm 24 and in the position shown, control pressure acts on the upper side of diaphragm 24. However, when solenoid 27 is energized, the effective control area becomes that of diaphragm 25, thus reducing the equilibrium brake pressure. <IMAGE>

Title: Testing terminal unit and plug
IPC: H01R9/26
Filed: 1980-03-10
Abstract: An electrical terminal unit, primarily intended for connecting an ammeter to a current transformer secondary winding, has respective terminal members 3 normally interconnected by a resilient bridging contact 5, and testing contacts 4' for connecting the terminal members to test apparatus by means of a test plug 12. The testing contacts 4' extend beyond the bridging contact by an amount greater than that by which the plug contacts 10 are set back from the forward end 9 of the plug. The forward end of the plug serves to disconnect the bridging contact when the plug is inserted, after the plug contacts have made contact with the testing contacts, so that the transformer secondary circuit connected to the terminal unit remains closed. <IMAGE>

Patent GB-2055005-A (GB)
Title: Multi Planar Image Editor
IPC: H04N11/00
Filed: 1978-08-25
Abstract: Television/photographic camera arrangement includes an optical arrangement which causes the image light from the camera's main lens system to be focused on two or more planes at different distances from the main lens system, e.g. for three such planes the resulting sub-images are arranged to include in-focus objects located in the far, middle and near distance ranges respectively from the main lens system. These sub-images are then analysed and the in-focus portions thereof selected and used to form a composite image which is substantially in-focus at all points. The sub-images are analysed by television cameras e.g. three colour television cameras, and the resulting video signals (specifically the luminance signals) are analysed e.g. by digital filtering, to determine those regions of each sub-image which are more in-focus than the corresponding regions of the other sub-images. From this in-focus determination a switching control signal is formed for selecting the in-focus video signals for transmission or recording. The in- focus selection may be effected by first recording the sub-image video signals on magnetic tapes and erasing the out-of focus portions. Cine or still photographic cameras may simultaneously record the sub- images and during the processing of the films those portions not in-focus are suppressed from each frame according to the compared television signals, the films then being combined to form a master film. Also described is an arrangement in which a single image is photographed or televised, and those regions which are determined to be out of focus e.g. by digital filtering, are mathematically enhanced under operator control to improve their sharpness so that they appear to be in focus.
