Patent GB-785842-A (GB)
Abstract: 785,842. Overhead current systems for electric traction. JACQUEMOND, J. Feb. 8, 1955 [Feb. 13, 1954], No. 3676/55. Class 104 (3). A direct or alternating current three-wire overhead supply system for trolley vehicles has the third conductor spaced above the two power conductors which are spaced apart in the same horizontal plane. The system has three overhead conductor wires 5, 7 and 8 supported from a catenary 1 through hangers 6, 6<SP>1</SP> attached to members 11 which directly carry the third conductor 5 and support the power conductors 7, 8 through an insulating bar 13 and respective insulators 14, 15, the central and neutral third conductor wire 5 being connected directly to earth through the member 11, hanger wires 6, 61, catenary 1, bracket 2 and either through the post 3 or an earthing wire. Swinging of the insulator bar 13 is prevented by a stay 10 extending from the post 3 to an extension 13<SP>1</SP> of the bar 13. The power is collected by a single collector head 19 which is mounted by a ball and socket joint 20 on the end of a collector arm 22. The shoe 25 engaging the neutral wire 5 is guided therealong by check plates 26. The power wires 7 and 8 are engaged by shoes 31, 32 mounted on arms 29, 30 resiliently mounted at 35 on spigots 34 attached to insulating plates 28 secured one on each side of the head 19. The shoes 31, 32 are connected by wires 38, 39 to terminal blocks 40, 41, mounted on an insulating sleeve 23 on the pole 22, and are connected to the trolley vehicle equipment by cables 42, 43. The neutral wire 44 of the trolley vehicle equipment is earthed to the overhead wire 5 through the pole 22. The shoes 31, 32 are held in contact with the wires 7, 8 by springs 36 the upper movement being limited by stops 37. The ball and socket joint 20 is arranged at the centre of pressure of the shoes 25, 31 and 32 At crossings, Figs. 5 and 6, the neutral wires 5, 5<SP>1</SP> support a plate 45 formed with guiding cheeks 47 and upwardly inclined ends 48 so that on approaching collector head 19 on reaching positions B, C will be depressed by the cheeks 27, Figs. 3 and 4, engaging the underside of plate 45 between the guides 47 and so move the shoe 25 out of engagement with the wire 5, the earth connection, however, being maintained by the cheeks 27, plate 45 and wire 5. At the same time the shoes 31, 32 are disengaged from the wires 7, 8. A similar but reverse movement is effected at the outgoing end of the plate 45 to allow the shoe 25 to move into contact with wire 5. The line wires 7, 8 are supported by the plate 45 above the crossing at 51, 52, 51<SP>1</SP> and 52<SP>1</SP> and pass through sheathing 53. At the entrance and exit ends of the plate 45 the wires 7 and 8 are insulated by insulators 50.

Title: Removing Slag
IPC: C10J3/08
Filed: 1979-02-01
Abstract: In a slag removal and quenching apparatus the quenching means is located below the slag tap and a water reservoir, located within the quench chamber is provided with means to permit depressurisation and discharge of slag and water to atmosphere. As shown in the drawing the gasification plant includes a spiral pipe issuing water in jets towards a slag stream issuing from a slag tap which shock cools the slag which forms a frit that drops into a water reservoir. The water and slag frit is removed by a slag removal means after de-pressurisation of the water and slag. <IMAGE>

Title: Orthodontic bracket
IPC: A61C7/14
Filed: 1979-03-12
Abstract: An orthodontic bracket comprises:- a bracket body (20) with an open sided slot running along the labial side of the bracket from the mesial end to the distal end, the slot being for the reception of an arch wire (46 or 80); and a resilient retainer member (45) for retaining an arch wire in the slot, the retainer member being movable on the bracket body in the occlusal-gingival direction between a slot-closed position and a slot-open position; wherein the part (50) of the retainer member which closes the slot extends into the slot when it is in the 'slot closed' position, so that movement of the retainer member out of the slot-closed position takes place against its resilience as the opposed embracing retainer parts are moved apart. The arrangement is such that any force urging the arch wire out of the slot and contacting it with the retainer, thereby urges the retainer to the slot-closed position. <IMAGE>

Title: A Digital Time Domain Transversal Filter
IPC: H03H17/02
Filed: 1979-08-20
Abstract: The filter comprises two samplers (5 and 6), the first of which receives an input signal x(t) and the second of which receives the Hilbert transform signal @(t) of the input signal x(t), the samplers operating synchronously at the rate 1/T and respectively providing samples x(m) of the input signal x(t) and @(m) of the signal @(t), together with a calculator unit for transforming the sample pairs (x(m), @(m)) into output samples y(m) of an output signal, according to the relationship: <IMAGE> where m and k are integers and b(2k) and c(2k) are real weighting coefficients. It is convenient to use Hilbert transform when filtering single sideband signals, and the present filter makes use of both the input signal and its Hilbert transform, but without doubling the number of samples on which calculations are performed during any one sampling period. <IMAGE>
Patent GB-2039592-A (GB)
Title: Combined hinge and hold-open device
IPC: E05D11/10
Filed: 1979-08-28
Abstract: A combined hinge and hold-open device, for example for a motor vehicle door, is used to hold the door open until a predetermined holding force is exceeded by the closing force. The design of such a device is simplified by mounting a torsion bar 54 in one leaf 51 of the hinge so that the bar extends substantially perpendicular to the pivot pin 53 of the hinge. The torsion bar 54 has a transversely-extending arm 56 at one end thereof which is engaged by a cam surface 61 on one side 59 of the second leaf 52, a recess 62 in the cam surface providing the hold-open position of the hinge as the arm 56 is urged into the recess by the torsional action of the bar 54. A roller 65 is rotatably mounted on the inner surface of the second leaf 52 and extends beyond the cam surface 61. As the door is opened, the second leaf 52 moves from a closed position until the roller 65 engages the arm 56 of the torsion bar 54. <IMAGE>

Title: Methods of and apparatus for making lengths of tubing from cylindrical tubes
IPC: B23D21/00
Filed: 1981-03-04
Abstract: To cut a tube, preferably of plastics, into lengths of tubing, the tube is inserted into a tubular guide and one end of the tube is clamped in a clamp (10), whereupon the tube is rotated and cut into lengths by successively actuating a plurality of severing units (6) in the direction towards the clamped end (9), starting with the unit (6) furthest away from the clamped end (9). Each severing unit (6) comprises a cutting knife movable into contact with the rotating tube via a slot in the guide.
