Title: Magnetic suspension and propulsion system
IPC: B60L13/06
Filed: 1972-03-24
Abstract: 1385212 Control of A.C. motors ROHR INDUSTRIES Inc 24 March 1972 [19 April 1971] 13998/72 Heading H2J [Also in Division G3] In a system for electromagnetically suspending the moving part of a linear induction motor, e.g. for a tracked vehicle, with automatic means for keeping the gap constant (see Division G3), the speed of propulsion is controlled by adjusting the frequency of energization of the motor windings. Energization is from a three phase A.C. or a D.C. source via switching transistors or thyristors controlled by three phase signals produced by potentiometers having sliders spaced at 120 degrees and continuously rotated by an electric motor whose speed thus determines the speed of the linear motor. The energization may be phase retarded to provide regenerative braking. The motor has a three phase winding on its movable part 1, and as shown this is supplied with energy and co-operates with the laminated steel stationary part 2. In one alternative arrangement the stationary part has a "squirrel cage" winding of aluminium impressed in steel laminations (Fig. 7, not shown) or a solid aluminium strip may be combined with the steel. In another alternative the stationary part is a plain steel rail (Fig. 8, not shown), and propulsion is by hysteresis effect; preferably the steel has a "square loop" magnetization curve, or it may alternatively be made of a ferrite.

Abstract: 808,388. Repairing tubeless tyres. JOHN BULL RUBBER CO. Ltd. May 1, 1957 [May 9, 1956], No. 14482/56. Class 144 (1). [Also in Group VIII] Punctures in tubeless tyres are first enlarged, and then plugged, by means of a tool comprising a tubular member 18 having a handle 16 at one end 24 and a screw thread 19 at the other end terminating in a cutting edge 20 at the extremity of the member. As shown, the cutting edge 20 is serrated or toothed, and the end 24 is also screw-threaded for detachable attachment to the handle 16. The handle 16 comprises a winged boss having a through bore which is stepped and screw-threaded at one end 17 to receive tubular members 18 of two different diameters, and is screw-threaded at its other end 23 to receive the nozzle 28 of a collapsible tube 27 of rubber solution. A series of transverse holes 22 are provided in the walls of the tubular member, intermediate its ends, of which a diametrically opposed pair may serve to receive a tommy bar 12 for facilitating screwing of the member 18 into or out of the handle 16. The bar 12 is pointed at one end 14, and cranked at its other end 15, to serve as a nail extractor, Fig. 1, and is of a diameter to pass through the handle 16 and tube 18 and project therefrom as shown in broken lines in Fig. 2 to serve as a probe to lead the cutting edge 20 into the puncture. In use, rotary motion of the tube 18 under axial pressure causes the screw thread 19 to progress the cutting edge 20 through the tyre tread. On withdrawal of the tube, the cut core is removed therefrom by the bar 12 and the tube is then detached from the handle 16. A mushroomheaded, long-tailed rubber plug 26 is inserted into the tube, Fig. 4, until the head 26 abuts the blunt end 24, the surplus tail end being severed as shown against the cutting edge 20. The handle 16 is then applied to the tube end 19 and the plug forced into the enlarged puncture, rubber solution having previously been injected into the puncture by the collapsible tube 27. The nozzle 28 of the tube 27 is then screwed into the rear end of the handle 16, Fig. 7, and rubber solution is injected into the tubular member 18 to surround the plug and ooze out through the holes 22. Rotary withdrawal of the tubular member 18 spreads the solution on the inner surface of the tyre around the puncture and leaves the plug in the puncture with its head 26 firmly abutting the solutioned tyre surface, Fig. 8.

Title: Improvements in and relating to means for retarding the movement of vehicles
Inventor: PENN ARTHUR
IPC: B61K7/02
Filed: 1959-04-29
Abstract: 875,217. Track brakes. SIMON-CARVES Ltd. April 11, 1960 [April 29, 1959], No. 14645/59. Class 103 (1). A device for retarding vehicles comprises a portion 20 slidably associated with a portion 21 fixedly secured in the path of the vehicle, hooklike catch means 50 pivoted to portion 20 being projected into a position for engagement by the moving vehicle by a wedge-like slide 53, and a retarder to decelerate portion 20 and the vehicle. A spring 64 moves slide 53 and the catch means 50 is locked in position by the mating surfaces 71, 70. A lug 27 of portion 20 carries a rod 29 and piston 34 in a cylinder 31 of portion 21; a tapered pin 39 is coaxial with cylinder 31, a port 40 in piston 34 and with a blind bore 42 in rod 29. In operation, the catch 50, portion 20, rod 29 and piston 34 are moved with the vehicle to force fluid from chamber 33, via ports 40, 47, 46, to the chamber 79, Fig. 3, of an oleo-pneumatic recuperator 45, the piston 81 of which being moved from stop 82 into chamber 78. The pin 39 gradually closes port 40 to progressively decelerate the vehicle until, when piston 34 engages a collar 43 on pin 39, the vehicle is stopped. A control over the deceleration may be exerted by a needle valve 77 in a vent passage 75 connecting opposite sides of piston 34. To release the vehicle, air pressure admitted via pipe 73, moves piston 63 and slide 53 to permit the catch 50 to rotate and release the vehicle. Air pressure is also admitted to recuperator chamber 45 to move piston 81 and force fluid from chamber 79 via ports 46, 47, blind bore 42, an annular chamber 87 and ball valves 88 in piston 34, Fig. 9, to chamber 33 to return piston 34, rod 29 and portion 20 to their initial position. Pipes 73 and 85 are then connected to atmosphere to permit spring 64 to reset the catch and to relieve pressure in chambers 79, 33. The vehicle is then moved forward by a ram. In Fig. 7, not shown, after a predetermined movement of portion 20, a projection on the slide engages a stop to withdraw the slide and release the vehicle, at this time a reduced diameter portion of the tapered pin permits a more rapid fluid flow through the piston; the vehicle is thus released at a predetermined speed determined by the taper of the pin and the position of the stop.

Title: Spark Gap and Discharge Control Apparatus.
IPC: H01T4/20
Filed: 1967-03-31
Abstract: 1,173,685. Surge diverters. OHIO BRASS CO. 31 March, 1967 [11 Oct., 1966], No. 14738/67. Heading H2H. A multi-stage surge diverter selectively responsive to surges having respectively slowly rising and fast rising wavefronts (e.g. switching surges and lighting surges) comprises the arrangement shown in Fig. 2 in which main spark gaps 21-24 are respectively shunted by pre-ionizer gaps 32, 36, 42 and by a capacitor 40, and also by grading resistors 35, 39, 41, 45. The value of resistor 41 is small relative to that of the resistors 35, 39, 45 which are of equal value, whilst the resistors in series with each pre-ionizer gap are chosen so that their value per stage progressively decreases from a maximum in stage S1 to a minimum in stage S4, the gaps 32, 36, 42 being designed to spark-over at substantially the same voltage. When a surge with slowly-rising wave front appears on the line 28, gaps 32, 36, 42 spark-over and alter the voltage distribution across the stages S1, S2, S4, so that the main gaps 21, 22, 24 fire in that order followed finally by the gap 23. During initial discharge of the gaps 21-24, the gaps 30, 31 spark-over until their arcs are extinguished by a magnetic blow-out coil 25 which thereafter serves to extinguish the arcs across the gaps 21-24. When the surge on line 28 is one with a rapidly-rising wave front, the voltage distribution across the stages is determined by the distributed capacitance of which the capacitor 40 is chosen so that the greater part of the impressed voltage is divided across the stages S1, S2, S4. These then fire in an indeterminate order determined primarily by the voltage variation between the stages caused by the impressed wave front, the stage S3 again being the last to fire. The arrangement of Fig. 2 may be made symmetrical by replacing members 36, 37, 38 by a capacitor (75), Fig. 5 (not shown), the values of the grading resistors and capacitors being chosen to obtain desired firing orders which may or may not be similar to those already described. In a modification of the symmetrical arrangement the grading resistors of the first and last stages are omitted. In both the described embodiments, it is preferred that the total resistance of the switching gap branch, when the gap is fired, should be less than the resistance of the associated grading resistor. The various stages of the arrester are constructed and arranged in the manner disclosed in Specification 1,173,686.
