Title: Improvements in or relating to railway car retarders
IPC: B61K7/04
Filed: 1955-05-03
Abstract: 781,904. Railway car retarders. GENERAL RAILWAY SIGNAL CO. May 3,1955 [May 6, 1954], No. 12786/55. Class 103 (1). A railway car retarder control system, as shown generally in Fig. 1, comprises a retarder unit (No. 1, No. 2) located on the hump and further units Nos. 3-14, located in the respective group of shunt yards, the performance of a car in passing from the hump retarder units to the group retarders being measured to determine the car's rolling resistance and the leaving speed from the group retarder units being adjusted in accordance with this resistance, to brake the car in the desired position. The car retarders are preferably of the weight automatic type, as shown in Fig. 3, in which the rails 50 are supported on hook arms HA pivotally coupled to floating levers L, such levers applying force to the wheels through the brake shoes S in accordance with the weight of the vehicle and the movement of cams C on each side of the track, which are rotated by shafts 56 coupled by a chain drive 62, as shown in Fig. 9. The cams are of a type which must be rotated through 270 degrees to give full application of the brake shoes S, whereas the shoes may be fully released by only 90 degrees rotation. The cam shafts are driven by a motor 60 through suitable reduction gearing 61. Figs. 10 and 11 show typical control circuits for hump and group car retarder units. The approach speed of a car towards the hump car retarder is determined by a radar speed detector or " interferometer" device DA which actuates control circuits so as to adjust the brake bars of the hump retarder to give a definite leaving speed such as 12 miles per hour. A further radar speed detector DA1 associated with the group car retarders determines whether the speed of a car has increased or decreased from the 12 m.p.h. in passing between the two retarder units, thus giving a measure of the car's rolling resistance and relays S, 5, 8, 12 or 14 are accordingly operated to further decrease the speed of the car as necessary to a selected leaving speed such as 5 miles per hour. Further more elaborate control circuits are described for use in arrangements wherein each car retarder comprises multiple brake units and in which the track includes weight registration means for determining the weight of the car passing over it. Specifications 303,446, [Class 103 (i)], 753,069, [Group XL (c)], 781,903, [Group XXXVII], and U.S.A. Specification 2,038,112 are referred to.

Filed: 1937-07-06
Abstract: 504,174. Converting. GENERAL ELECTRIC CO., Ltd., and DUNHAM, C. R. July 6,1937, No. 12942. [Class 38 (ii)] Peaky control potentials for a polyphase converting arrangement are obtained from a single phase supply by means of an impedance network which includes a plurality of saturable reactances from which the potentials are derived. In the form shown in Fig. 1, three parallel connected networks, each containing an impedance Z1, a series resonance circuit LC1 and the primary of a transformer, are supplied from a single phase circuit L1, L2. The impedances Zl arc respectively inductive, resistive and capacitative so as to give currents through the transformers T1 mutually 60‹ phase displaced. The transformers T1 operate at saturation to give peaky potentials. Phase adjustment is obtained by varying the phase of the single phase supply. In the form shown in Fig. 2, phase displaced control impulses are obtained from three transformers TI, T2, T3 operating at saturation and Laving their primaries connected in series across the supply L1, L2. Two of the transformers have tertiary windings T2a, T3a. which are connected to a source of D.C. B through a choke L and resis. tance R. Adjustment of the moments at which saturation occurs in the transformers T2a, T3a is effected by control of the current in the tertiary circuit. The Specification states that phase adjustment of the single phase supply may be remotely and/or automatically effected.

Abstract: 457,707. Granulating slag. BJORKMAN, E. B., 25, Montague Street, Russell Square, London. May 3, 1935, No. 13232. [Class 82 (ii)] [See also Group V] A method of producing porous light-weight aggregate from molten slag consists in rendering liquid slag porous by treating it with water or other volatile liquids or gases, cooling the porous slag to a viscous state, subjecting it to a mixing operation during which the mass is broken up into particles, and solidifying. The slag may be rendered porous and brought to a viscous state by causing it to flow down a sloping trough b, into which water in small quantities is admitted at the upper end (nozzle c<1>) and by blowing cold air or sprinkling water from above on to the slag in the trough (nozzle c3) The gas-containing viscous slag may be mixed, broken up and solidified by leading it on to the surface of a cooled revolving concave conical disc d having radially extending corrugations e which flatten out and merge into the surface of the disc at the central part and form vertical ledges towards the periphery. As shown water is sprayed on to the slag and disc through a nozzle c<2>. In a modification, the viscous slag is led into a cooled revolving sloping drum having at the upper end a contracted inlet formed with internal longitudinal corrugations.
