Title: Apparatus for detecting horizontal misalignment of a railway track
IPC: E01B27/17
Filed: 1963-10-15
Abstract: 1,067,825. Checking railway track alignment. CANADA IRON FOUNDRIES Ltd. Oct.15, 1963 [Oct.15, 1962],.No.38476/63. Heading G1A. In order to checK railway track alignment a wheeled carriage or a number of wheeled carriages are provided to support and carry an infrared test system. In a first embodiment carriage 10 is held with its wheel flanges hard against rail 25 by spring-loaded rod 16 terminated in wheel 18 pressing on the opposite rail. On the carriage  is mounted infrared transmitter 13 from which a beam of radiation is directed along the track towards infrared receiver 31. The receiver is mounted on a similar carriage 30 also held with its wheel flanges against rail 25. Between the carriages 10 and 30 is a third carriage 40, likewise held against rail 25 and carrying a board 41 whose edge is level, and in a position to interact with, the infrared beam. If the track is out of alignment as indicated by the dashed lines on the drawing the board 41 will obstruct the beam of radiation and receiver 31 will cause an indicator lamp to light. A similar system 13a, 31a, 41a checks for misalignment in the opposite direction. The receivers may also be used to control correcting means such as a hydraulic cylinder 42 pressing an anchor into the track ballast and a horizontally arranged double acting cylinder 45 pressing one of shoes 45a or 45b, against the track. As soon as the track has been pressed to its correct position, boards 41, 41a, will allow sufficient of the beams to pass to terminate operation of cylinder 45. In a modification, Fig.2, a single infrared transmitter 13b is used in conjunction with two vertically spaced receivers 31b and 31c. The board between them is shaped as shown so that the part 51 cuts off radiation to receiver 31c when the track is out of alignment in one direction, and the part 50 cuts off radiation to receiver 31b when the alignment error is in the opposite direction. In another embodiment the transmitter and receiver systems are placed at opposite ends of a single, long, rigid-framed vehicle Fig.3 (not shown) and the board is movable transversly relative to the vehicle and attached to a member spring-loaded to sense the rail position. In this embodiment rollers engaging the outside edge of track at the four corners of the vehicle make a ballast anchor unnecessary and if rollers are provided instead of shoes 45a 45b for operation by the correcting cylinder 45 the vehicle may be moved slowly forward in a continuous aligning process. It is possible to associate the present system with that described in Specification 1, 014, 324 so that horizontal and vertical deviation may be investigated and corrected using a single vehicle. If the alignment of curved track is to be investigated the board is moved sideways sufficiently to take into account the desired radius of curvature.

Abstract: 1,193,337. Transistor pulse circuits. ROBERT BOSCH G.m.b.H. 22 Aug., 1967 [24 Aug., 1966], No. 38528/67. Heading H3T. [Also in Division G1] The output of a monostable circuit KG, Fig. 1, in an I.C. engine injection control system, is fed to a circuit ST which shortens the pulse width of the monostable output by delaying the leading edge. The pulses from the circuit ST are made to start later than the monostable output pulses (T N , T G , Fig. 2, not shown) and to finish simultaneously, whereby a given variation in pulse width of the monostable output by resistor 34, connected to the inlet manifold pressure transducer 35, represents a larger proportional variation of the reduced width output of circuit ST. The monostable comprises a normally ON transistor T1 and a normally OFF transistor T2, a pulse from a cam-controlled switch A changing over the states of these transistors to apply a positive pulse to a capacitor 41 in circuit ST and a negative pulse to a resistor 40. Since the right hand plate of capacitor 41 is already positively charged through diode 43, the base of transistor T3 is taken even more positive, holding it cut off, until the positive voltage decays through resistor 40 to the point where T3 conducts. This represents the start of pulse (TN). In other embodiments, an NPN transistor is used in circuit ST (T4, Fig. 3, not shown), an NPN transistor replaces T2 (T5, Fig. 4, not shown), and a variable inductance transformer is used in the monostable KG as the pulse width varying device (Fig. 5, not shown).
