Title: Centralised traffic control system for railroads
IPC: B61L27/00
Filed: 1973-09-24
Abstract: 1452328 Central traffic control GENERAL SIGNAL CORP 24 Sept 1973 [22 Sept 1972] 44627/73 Heading B7N A central office control apparatus for setting track switches and signals at field stations FS1 ... FSn comprises a manual keyboard 103 for initiating commands for required settings of track switches and signals, an indicator 102 responsive to signals from the field stations indicating the actual setting of switches and signals and track occupation, a communication system 104 for signalling between the central office and the field stations and vice versa, and a central processing unit of computer 105 which responds to the keyboard commands and information from the stations to decide on and issue setting orders only when these are allowable. Interlock safety equipment (not described) is also provided at the field stations to prevent unsafe setting of switches and signals.  The communication system monitors each field station in turn to provide information on the actual setting of track switches and signals and track occupation for the indication files of the processing unit and the C.R.T. display 102. The display shows the whole of the track layout being controlled and also when the keyboard operator is working on a particular field station, shows an enlarged display of that field station. Assuming a track switch and signal change has to be carried out at a particular field station the operator actuates the keyboard and appropriate inputs are applied to a digital file. This causes a decision file for the appropriate station to be transferred, if it is not already there from a bulk memory to the internal memory of the processing unit. The particular tables of the decision file associated with the required changes are then selected and the changes are checked for permissibility. The switch change instruction, if permissible, is now transferred with the location address to a central file and the signal change instruction, if permitted, to a flag file. At this time if a code start switch has been actuated by the operator to execute the changes an entry is made in a code start file and the digital file is cleared. At the next space between scans of the field stations the code start file is interrogated to determine if a code start is pending and if so the location number is generated and the contents of the control file are transmitted to the field station to be changed. When correspondence between the desired and actual position of the track switch is achieved the signal change is transferred to the control file and thence to the field station. Figure 9 (not shown) illustrates the manner in which the field stations are displayed on the C.R.T. indicator, how the track plan is formed from characters and how the normal and reverse positions of the track switches and the clearing of the signals and occupancy of the track is shown. Where a particular change has been requested the indicator flashes until the change is carried out in the field.

Title: Process and apparatus for examining transparent sheet materials
IPC: G01N21/896
Filed: 1961-12-13
Abstract: 1,004,472. Photo-electric determination of transparent sheet quality. COMPAGNIE DE SAINT-GOBAIN. Dec.13, 1961 [Dec.13, 1960], No. 44669/61. Heading G1A. In a process for the continuous estimation of the polish quality or the body quality of a transparent sheet, where-in a point image of a light source is formed on the transparent sheet by optical means, at least as small as the smallest flaw to be detected, and the light passing through the sheet and/or being scattered therby, is directed by further optical means on to photo-sensitive means, a filter and a counter filter are arranged in the light path, optically conjugate to each other, on either side of the sheet, such that light passing through the filter and an unblemised part of the sheet is obstructed by the counter filter, whilst scattered light, caused by blemishes in the sheet, passes the counter filter to be detected by the photo-sensitive means for producing a recorded output. In the embodiment shown, a glass sheet 6 moves perpendicularly to the paper relative to an optical system comprising a slit light source 1, rays from which are focused on the glass sheet by a concave mirror 5 and directed on to a photomultiplier 13 behind a slit 12 by a second concave mirror 7. The filter is in the form of an attenuator 3 comprising a rectangular obstruction 4 and is placed in optical conjunction with the counter filter 8 comprising a similar rectangular aperture 9, such that the image of the obstruction 4 is formed on the aperture 9, thus preventing light from source 1 reaching the photo-multiplier 13 except when it is scattered by blemishes in the glass sheet. The relative movement between the sheet and optical system may be caused by the movement of the sheet or system alone or by the movement of both. Lenses can be used instead of the concave mirrors. The filter may comprise a phase plate or a doubly-refracting prism or any other device to provide interferential contrast with the counter filter which may comprise a slit or a plurality of slits in an opaque sheet.

Filed: 1975-10-29
Abstract: 1522650 Watches A SCHILD SA 29 Oct 1975 [1 Nov 1974] 44694/75 Heading G3T In a watch movement having a stem 2 movable axially between a winding position (shown) and a setting position, a pinion 19 is fast for rotation with the stem but axially fixed so as to be permanently in mesh with an intermediate setting wheel 21 and a slidably mounted winding wheel 36 Fig. 3, a second intermediate wheel 23 is controlled by the stem to uncouple the setting wheel 21 from minute wheel 15 when the stem is in its winding position, and a device controlled by pullout piece 8 ensures that the winding wheel 36 is moved out of mesh with barrel ratchet wheel 27 when the stem is in its setting position. As shown this device comprises a lever 33 which can pivot about a stud 34 (under the control of a stud 41 on the pull-out piece co-operating with a slot 39 and incline 40 of the lever) and which has an elongated aperture 35 embracing the pivot shaft of the winding wheel 36. In the winding position shown, rotation of the stem in one direction causes the wheel 36 to drive the ratchet wheel 27 in the direction of arrow 31, whereas the wheel 36 slips out of mesh with 27 when the stem is turned in the opposite direction. When the stem is pulled out for setting, the lever 33 pivots clockwise and shifts the wheel 36 away from the ratchet wheel. The latter may also be wound by an automatic train terminating in a pinion 30, and its reverse rotation is prevented by click 29. The stem may also occupy an intermediate position, determined by a notch 42 in check spring arm 12, in which neither winding nor setting occurs but a lever 49 is free to pivot about a post 63. A pinion 54 mounted on the lever 49 meshes with the wheel 21, and rotation of the stem then corrects a date ring 43 or a day dial 45 depending on the direction of rotation.

Title: Magnetic core storage system
IPC: G11C11/20
Filed: 1963-11-18
Abstract: 1,038,299. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1963 [Nov. 28, 1962], No. 45362/63. Heading H3B. In a two core per bit memory system, reading is effected by passing read current signals comprising an alternating component through wires traversing the cores to change the state of one of the cores, thereby inducing on a sense winding an oscillation whose phase is determined by the identity of the core which changes state. A two word system, each word of two bits, is shown in Fig. 1. In order to write a " 0 " bit in cores B1, B0, a writing D.C. pulse C5, Fig. 2, is passed along wire 3 in coincidence with a train of oscillations C1 along column winding 1 so that core B1 is demagnetized and core B0 is saturated. To write a " 1 " bit switch 6 is moved to feed a write D.C. pulse to wire 2 instead of wire 3. Reading is effected by passing a train of oscillations, analogous to C1, down wire 1 such that flux oscillations are induced in the sense or read wire 4, the oscillations. produced in the saturated cores being of much smaller amplitude than those produced in the demagnetized core. Since the flux oscillations induce in wire 4 opposing E.M.F.'s a sinusoidal resultant signal is generated in the wire 4 whose phase depends on the value of the bit which is read, the resultant signal being used to determine the phase of phase-sensitive device 7. In the arrangement of Fig. 3 (not shown), wires 2, 3 of Fig. 1 are replaced by a single writing wire and when a bit has been written one of the cores is saturated in a positive direction and the other in a negative direction. Writing is again effected by the coincidence of a D.C. pulse, the polarity of which determines the bit to be written, and a train of sinusoidal oscillations on the writing and column wires. Reading is effected by passing a train of sinusoidal oscillations superimposed on a D.C. pulse through the appropriate column wire, the phase of the signal induced in a sense wire again being used to determine the phase of a parametron. In the arrangement of Fig. 6 two simultaneous trains of oscillations are sent respectively on a column wire such as 11 and on a pair of line wires 12, 13. Writing is effected by sending, in addition to the two trains of oscillations, a writing D.C. pulse on the writing 14, the polarity of which determines the value of the bit to be written. Reading is effected by sending on the pair of line wires 12, 13 a train of sinusoidal oscillations and on the column wire 11 an identical train superimposed on a D.C. pulse, the resultant signal induced in reading wire 15 being in the form of an oscillation whose phase represents the value of the bit read.
