Patent GB-746443-A (GB)
Title: Improvements in or relating to control systems for railway car retarders
IPC: B61K7/12
Filed: 1954-05-13
Abstract: 746,443. Railway car retarders. GENERAL RAILWAY SIGNAL CO. May 13, 1954 [June 2, 1953], No. 14035/54. Class 103 (1). In a railway car retarder, particularly for hump shunt yards, control is carried out by selecting automatically the degree of retardation in accordance with the weight of a car and operating the retarders so that they are released when the speed of each car has been reduced to that which will allow that particular weight of car to reach its destination. The general arrangement of the system, as using two retarders, is shown in Fig. 1, use being made of radar antennas 1DA and 2DA to measure the speeds of cars passing through the retarders and in conjunction with signals received from the weight detector WD to provide through the retardation stage selectors control of car retarder mechanisms 1-CRM and 2-CRM which release the cars at the required speed. The operation of the retardation stage selectors is also subject to control by levers 1MM and 2MM which select "High," "Normal" and " Low " car leaving speeds and levers 1MS and 2MS which may be adjusted to any of positions 0, 2, 3, 4 to provide for further more selective variation of the car leaving speeds. The control circuits used to combine the actions of the weight detector WD and signals received from the radar antennas 1DA and 2DA are shown in Figs. 2A and 2B. The weight of a car on the movable track rail is caused to operate a plunger 8 against a spring 9 so as to bridge over a finger 11 to any of three position contacts 13, 14, 15 which operate relays LW, MW, or HW according to whether the car is of low, medium or heavy load, it being found that more selective weight control is unnecessary. An electric signal varied in relation to the speed of a car as detected by the radar device 1DA and 2DA is applied to the cathode followers 21 and 22 of the speed detectors 1SD and 2SD so that a corresponding current output is applied to lines 16 and 59 which are connected to one of three circuits as selected by the levers 1MM and 2MM which operate through relays 1L, 1H and 2L, 2H. The further control by levers 1MS and 2MS determines which of the lines 0, 2, 3 and 4 shall become effective to control the car retarder mechanisms 1CRM and 2CRM. A table giving suggested high, normal and low car leaving speeds for a range of loads is provided, and it is explained how for cuts of cars comprising combinations of low and medium or heavyweight cars, the relays will be operated to establish retardation appropriate to the heavier weight of car. The composition of a speed detector of the continuous wave radar type is described in detail with reference to a further figure. Specification 303,446, [Class 103 (i)], is referred to.

Title: Improvements in or relating to high frequency heating systems
IPC: H05B6/78
Filed: 1953-05-19
Abstract: 726,359. High-frequency heating. AKTIEBOLAGET BOSTADSFORSKNING. May 19, 1953 [May 23, 1952], No. 14067/53. Class 39 (3). [Also in Group XL (c)]. In apparatus for heating by high frequency a plurality of supports, carrying a work piece or pieces, are moved past antenna plates connected to a high frequency generator. In Fig. 1, supports in the form of carriages 2 run on a track 1, and each work piece 3 forms the dielectric of a condenser having electrodes 4, 5, which may also act as clamping plates. Antenna plates 6 are connected to the electrodes 4 and pass close to transmission plates 7 connected to high frequency electromagnetic wave generators 8 each of which are earthed to the track 1. Variable inductances 9 are shunted across the electrodes 4, 5 and the circuits formed may thus be separately tuned. The transmission plates 7 are spaced by a distance 10 at least equal to the length of each antenna plate and have a length corresponding to a whole multiple of the pitch between the antenna plates 6 thus providing an approximately constant load on each generator. Fig. 2 shows a tuning inductance in which a metal strip 14 is displaceable along wire arms 12, 13, the inductance being connected across electrode plates 4<SP>1</SP>, 5<SP>1</SP> mounted in a clamping plate 11. The transmission capacity may be increased by making both transmission plates and antenna plates from several metal sheets which interengage but which are insulated from each other. The above apparatus may be embodied in a press for glueing laminated wood. For heating metal, a coil inductor is provided and tuned by a variable condenser. Specification 649,345, [Group VIII], is referred to.
