IPC: B61L25/02
Filed: 1965-06-17
Abstract: 1,081,474. Automatic train control. SIEMENS A.G. June 17, 1965 [June 19, 1964], No. 25769/65. Heading B7N. In an arrangement for controlling the direction of drive of a rail vehicle capable of moving in either direction with either end of the vehicle leading, means are provided for supplying the vehicle with a route direction signal via a pickup arrangement which also supplies the vehicle with an indication of its orientation on the track. The vehicle is provided with two pickup coils A, B, one on either side of the longitudinal centre line of the vehicle which cooperate with crossed loops which extend alternately adjacent one rail then adjacent the other rail of the track. The two coils are connected to a comparison device V which connects the coil receiving the maximum signal to direction determining device R, in addition the signal is applied to a transducer U which supplies a route direction signal to the device R. The device R determines from the signal and the coil receiving maximum signal the movement order for controlling travel direction switch F. The crossings in the loop conductors are used in conjunction with counter Z and the direction signal to indicate the position of the vehicle and on change over from one loop to the next an additional signal is transmitted to the vehicle which returns the counter to zero.

Abstract: 1275868 Stretching films CHEMIEFASER LENZING AG 5 May 1970 21683/70 Heading B5B In an apparatus for stretching films of thermoplastic material where conveying rolls, heating, stretching and cooling rolls are used, one or more electrodes are arranged to give an electrostatic charge to the film in contact with the first stretching roll and within a short distance, that is within 7À5 and 10 times the thickness of the non-stretched film, there is a further stretching roll capable of running at a higher speed than the first roll and located within the field of a further electrode. The emission of the electrodes associated with a particular roll impinges upon that part of the film in contact with the surface of the roll in such a fashion that the affected part of the film subtends an angle of at least 30 degrees at the centre of the roll. Two electrodes may be used in association with the first stretching roll so that the combined overlapping fields affect the film in contact with the roll 1 to the extent that this affected part of the film subtends an angle of 180 degrees at the centre of the roll. The stretching rolls have preferably a diameter of between 40 and 120 mm. and their surface is preferably sanded or otherwise roughened. In the embodiment shown in Fig. 3, the film is heated by rolls 4, 5, 6, 7 and 8 and stretched in the gap S 1  between rolls 10 and 10<SP>1</SP> and further stretched in the gap S 2  between rolls 16 and 16<SP>1</SP>. The stretching is preferably such that 80% is carried out between the first pair of rolls. The first roll of each pair is subjected to the influence of electrodes 11 and 11<SP>11</SP>, and 111 and 111<SP>11</SP>, and the second by electrodes 11 and 111 in accordance with the preferred arrangement.

Title: Load control valve for vehicle air springs
IPC: F16K31/36
Filed: 1958-08-12
Abstract: 839,103. Adjusting body height. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE .CO. Aug. 12, 1958 (Sept. 13, 1957], No. 25893/58. Class 108(2) A levelling valve for an air spring suspension system, has two inlet valves 28, 32, Fig. 3. Compressed air enters the valve through an opening 50 and passes out to the air spring through an opening 78. An arm 18, connected to an unsprung portion of the vehicle, operates the levelling valve. Arm 18 rotates a cam 92 to raise or lower members 80 and 66. For small movements of the arm 18, members 80 and 66 raise the valve 32 from its seat 42 and allow air to enter the springs, the rate of entry being controlled by an orifice 60. Orifice 60 is relatively small and the rate at which air enters the air spring is correspondingly low. For large movements of arm 18, members 80 and 66 lift the valve 32 until it abuts the valve 28 and lifts it off its seat 40. The rate at which air enters the air spring is now much higher and is controlled by the larger orifice 52. Small movements of arm 18 in the opposite direction cause members 80 and 66 to move downwards thus uncovering an orifice 72. Air is now exhausted from the air springs through the small orifice 72 and passages 70, 82, chamber 94, and orifices 104. If the movement of arm 18 allows further displacement of members 80 and 66, member 80 continues to move downwards but member 66 is held back by a ring 76. Thus, orifice 82 is the orifice which controls the rate of flow of air from the air spring to atmosphere. In a further embodiment, members 66 and 80 are combined into one member. In this case there is only one rate at which air may be exhausted from the air spring. The valve operating arm may incorporate a lost motion device. An arm 110, Fig. 6, operates a control arm 120, through adjustable stops 116, which contact ears 122, 124 of the arm 120. The arm 120 rotates the cam 92 as previously described.

Abstract: 1,000,542. Endless conveyers. UPJOHN CO. June 23, 1964 [June 24, 1963], No. 25918/64. Heading B8A. Articles on an endless conveyer 2 carry labels 3 each of which bears a code pattern, means being provided to compare the pattern with that on a standard label, any container carrying an incorrectly coded label being ejected from the conveyer. A motor 9 rotates a disc 5 in close proximity to each label as the articles successively pass on the conveyer. The disc 5 carries a permanent magnet 10 and a transducer 11. magnetic code strips 4 on the label 3 (see the standard label 3 on panel 14) are caused by the magnet 10 to energize the transducer 11 to produce a series of spaced electric pulses. These are dealt with in logic circuitry which incorporates a suitable time delay, so that an incorrectly labelled article is ejected further downstream by a ram 16. Alternatively, the magnet 10 may be replaced by a source of heat and the transducer 11 is then responsive to heat radiation.

Title: Improvements relating to valve mechanism for fluid under pressure
IPC: G05D16/10
Filed: 1945-10-09
Abstract: 601,865. Valves controlled by auxiliary valves. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and KERSHAW, N. G. Oct. 9, 1945, No. 26292. [Class 135] A valve mechanism for controlling the supply and release of fluid pressure to pneumaticallyoperated apparatus is operated by two or more pistons or like abutments 6, 11, each actuated by fluid under pressure under a separate control, one of the pistons 6 being arranged to actuate the valve directly and all the pistons being mechanically coupled in a series or chain by means which permit of limited lost motion so that the supply of control pressure fluid to all the pistons is necessary to operate the valve. As shown, the valve comprises an inlet valve 3 and an exhaust valve 4 normally biassed by a spring 8 to cut off a conduit 9 leading to the pneumatically - operated apparatus from a supply conduit 2 and connect such conduit 9 to atmosphere through a further conduit 10. The pistons 6, 11 are connected by interlocking projections 17 on nuts 18 which serve to secure piston packings 20. The piston 11 is mounted in a detachable extension 12 of the valve body 1 closed by a cap 14. A shoulder 16 limits the inward movement of the piston 11 so that it cannot unseat the valve 3. Each of the control conduits 13, 15 has a manual control valve. By detaching the cap 14, further detachable extensions 12 with corresponding pistons and control conduits may be added, the units being interchangeable. Fluid pressure applied to the conduit 13 alone does not operate the valves 3, 4 since the lost-motion between the pistons 6, 11 is taken up and the fluid pressure acts equally but oppositely upon the two pistons. If pressure is applied only to the conduit 15, the piston 11 cannot move far enough to unseat the valve 3. Specification 286,818, [Class 135], is referred to ir the Provisional Specification.

Abstract: 998,647. Parachutes. G. Q. PARACHUTE CO. Ltd. July 2, 1964 [July 3, 1963], No. 26297/63. Heading B7G. A parachute comprises a canopy constructed of segments connected together by means which break under predetermined strains so that the number of segments effective, or the gaps between the segments varies with the speed at which the canopy is deployed. In one embodiment (Fig. 1) the segments 11 are connected by stitching from the apex downwards. The distance for which this connection extends determines the inflation of the canopy on deployment and is arranged so that part of stitching breaks when a predetermined load on the canopy is exceeded. Alternatively, a series of breaking ties 22 may connect adjacent segments, the ties being stronger near the apex. The segments are also connected at the apex by a cord 13 passing through loops 12. The segments have reinforcing tapes along some or all of their edges, and may have load-bearing tapes extending, e.g. centrally of each segment from the apex to the hem. In another embodiment (Fig. 3), series 17, 18, 19 of segments are attached to a central rigging line 21 by ties of different strength, the ties to 18 breaking, for example, at a deployment speed of 300 ft./sec. the ties to 19 breaking at 600 ft./sec., and the ties to 17 being strong enough to hold under the maximum load anticipated. The segments 17 may be connected by fine netting to improve stability. Since the maximum loads on the various segments are different, different materials may be used for them.

Abstract: 186,628. Eclairage des VÚhicules sur Rail. Oct. 3, 1921, [Convention date]. Exciting.-The voltage of a variable-speed auxiliary-brush dynamo is regulated by means of a variable resistance 3 and a fixed resistance 4 connected as two of the arms of a four-armed bridge of which the armature winding sections between the auxiliary brush C and the main brushes A, B form the other two arms. The field winding 2 is connected between the auxiliary brush C and the junction of the variable and fixed resistances. In a modification the field winding 2 forms a regulating winding, the main field winding being connected across the main brushes A, B or between a main brush and the auxiliary brush C. At low speeds the regulating winding assists the main field winding and at high speed opposes it. The resistance 3 is varied by an automatic regulator R which is dependent on the voltage of the generator. The regulator R may also be provided with coils carrying the whole or part of the current from the generator.
