Title: Improvements in or relating to railway signalling equipment
IPC: B61L19/06
Filed: 1956-03-02
Abstract: 802,088. Railway signals. STANDARD TELEPHONES & CABLES, Ltd. March 2, 1956 [March 9, 1955], No. 6605/56. Class 105. A railway signal governing access to a plurality of routes from a point and having a first and second aspect authorizing movement at high and low speeds respectively is under the control of two relays each controlling one aspect which are connected in series and that relay apertaining to the unwanted aspect of a route over which movement is to take place is shortcircuited as by a shunt containing a contact for each track switch giving entry to a reduced speed route, each such contact being operable to close when the corresponding track-switch is in a position for a high-speed route so as to short-circuit the second or. low speed aspect relay when a high speed route is to be established and to open the short-circuit on the low aspect relay and establish a short-circuit on the high-speed aspect relay when the corresponding track switch is in a position required for a reduced speed route. In the event of a failure in a shunt circuit the two aspect relays are operable in series to give an indication of such failure. As shown, for a high speed route from signal F, Fig. 1, to signal N, the low speed signal SF2 is short-circuited by contacts W31, W41, W61 in the reversed positions to those shown, of devices indicating the normal positions of the facing points W3, W4, W5 (similar contacts for the trailing points may also be included) so that when the route is set or locked the relay SF2 is shunted and the high-speed aspect relay SF1 is operated over, the circuit from + battery, contact AN (normal) supervisory relay UN for signal N, contacts U6 + ... U1 + (all operated to indicate that the points W1-W6 are in their normal positions), supervisory relay UF for signal F, contact AF, operated when the route is established, contacts W61, W41, W31 all operated, winding of relays SF1 to -battery. For travel in the opposite direction from signal N to signal F, the relay SN1 would be operated over a similar circuit. For a route from signal F to signal M over the reversed points.W4, the relay SF2 is operated over a circuit from + battery and contact AM, supervisory relay UM for signal M, all not shown but similarly arranged to contact AN, and supervisory relay AN, contact U4 - (operated, showing the reversed condition of points W4), contacts U3 +, U2 +, U1 + (all operated, showing normal positions of points W3, W2, W1), relay UF, contact AF (operated) relay winding of the low speed aspect relay SF2, contact W31 (operated), contact W41 in position indicated to negative battery. The contact W41 removes the shunt from relay winding SF2, and places a shunt across relay winding SF1. The contacts W31, W41, W61 may be made dependent upon the locking of the points instead of their positions in which case the contacts would occupy the positions shown until the points are locked in the position for a high speed route.

Abstract: 692,981. Automatic weft control systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 21, 1952 [March 22, 1951], No. 7359/52. Class 38 (iv). [Also in Groups XXXVI and XL (b)] Apparatus for straightening the weft of moving woven material comprises two rotating lamps passing light through the material on to two photo-cells, whose outputs, consisting of an H.F. undulating voltage of L.F. varying magnitude, are compared individually with a standard voltage and combined to produce skew and bow correcting voltages. The lamps 9, 11, Fig. 1, shining through opposite edges of a width of the material 23, are driven by identical gears from a motor 2 which also drives a reference signal generator 28. The beams 21, 22, which are made elongated by suitablyshaped filaments are focused on the material 23 and fall on photo-cells 26, 27 whose output voltages are as shown in Fig. 4, and are demodulated to pass the upper L.F. envelope only. The modulation voltages are phase-compared separately with the reference signal from 28, giving a D.C. output voltage whose magnitude and polarity depend on the magnitude and direction of the phase angle difference. Thus with a skewed weft, the D.C. voltages are equal in magnitude and sign, and are added to actuate a skew control motor 54, Fig. 11, and when the weft is bowed, the D.C. voltages are equal in magnitude but opposite in sign, and their difference is made to actuate a bow control motor 56.
