Filed: 1971-03-03
Abstract: 1275535 Digital computers INTERNATIONAL BUSINESS MACHINES CORP 3 March 1971 5931/71 Heading G4A A digital electric data processing arrangement in which two or more district processes may be performed concurrently comprises a plurality of serially reusable resources (i.e. units that can be used by only one process at a time) and means for identifying the sequence of use of the resources by means of graph theory. A scheduler receives data concerning the resources and sequencing of the processes and constructs a digital vector graph which indicates whether a complete vector circuit exists or not and this is displayed on a CRT or printed out. This is stated to prevent deadlock situations occurring i.e. where two processes are waiting for each other. The Apparatus.-This comprises a central processor having a microcode store, an arithmetic unit, several other stores and the scheduler. Connected thereto are a disc store, a multiplexer, and three channels connected respectively to a console or card reader/punch devices, a display unit, and disc stores. Two processes or more can be performed concurrently. Operation.-Four processes I-IV respectively use the following resources in these sequences: A, C ; A, B, C ; A, B, D, C ; C, B. In Fig. 5A each resource A to D is shown as a vertex of a graph and each process is shown as a path (i.e. a number of arcs between vertices). The scheduler has two stores FOSTACK and FLAGSTACK and the following algorithm is performed: 1. The vertices of the graph G without predecessors (i.e. A) are stored in FOSTACK. If FOSTACK is then empty step 4 is performed, if not step 2 is performed. 2. The top vertex from FOSTACK is deleted and all its successors (i.e. B, C) are stored in FLAGSTACK (Fig. 5C, not shown). 3. One vertex is taken from FLAGSTACK, checked for predecessors, and if it has none it is stored in FOSTACK. This is repeated until FLAGSTACK is empty. Both B and C have predecessors, G is unchanged, FOSTACK is empty hence there is a circuit. 4. If FOSTACK is empty and all vertices are deleted from G, there is no circuit. If there are vertices in G there is a circuit. If FOSTACK is not empty, step 1 is returned to. Figs. 5E and 6 (not shown) indicate how matrix theory can be used for the schedules to store the graph and another embodiment is described using this (Figs. 7 and 8, not shown). If a deadlock is found, the operator is shown the circuit on the CRT and can remedy it by, for example, delaying the operation.

Abstract: 705,280. Semiconductor devices. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. March 13, 1951 [June 28, 1950], No. 6016/51. Class 37 A semiconductor device comprises a block 1 of semiconductor with electrodes 4 and 4<SP>1</SP> on each of its two end faces, and having a thin central portion of 1 to 500 microns thick, the thickness of the semiconductor increasing continuously and at an increasing rate; from the central portion to the end portions. Electrodes 4 and 4<SP>1</SP> are ohmic contacts. Various other shapes of semiconductor are described, including some which resemble a concavo-concave or convexo-concave cylindrical lens. It is alleged that shaping in this way facilitates the handling of these blocks while providing certain desired resistance characteristics in the thin central portion. A further electrode, comprising a point contact or an area contact, may be provided in the region of the thin portion. Shaping may be effected by moulding the semiconductor material, which may be germanium, on to a shaped core, and then grinding the opposite surface to produce the desired thickness. The electrodes may be of iron, copper, aluminium, silver, gold, or platinum. The arrangement is said to be applicable to rectifiers and transistors.

Title: Braking systems and/or tractive systems
Inventor: CRAWFORD KENNETH DESMOND EDDIN
IPC: G01P3/58
Filed: 1968-02-07
Abstract: 1,204,266. Automatic speed control. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan.29, 1969 [Feb. 7, 1968], No. 6106/68. Heading G3R. [Also in Division F2] In a wheeled vehicle the braking or tractive effort is reduced upon the occurrence of wheel slide or spin, respectively, due to loss of adhesion the control system being arranged so that the effort is reapplied slightly before full adhesion is regained. A first embodiment controls only the braking effort. An A.C. tachometer generator coupled to a braked axle applies a frequency proportional to wheel speed at terminals 1, 2. This is converted by a Schmitt trigger 5 and diode pump 11-14 to a D.C. voltage X proportional to the speed. The voltage X is applied through a differentiating capacitor 30 to an amplifier 31 which thus delivers an output at 32 dependent on the deceleration of the wheel. When this deceleration exceeds a value pre-set by a potentiometer 40, transistors 36, 37 are triggered to energize an electromagnetic valve 38 to reduce the hydraulic brake pressure. When transistor 37 becomes conducting a transistor 22 is cut off. This greatly increases the time constant of the circuit around capacitor 30 so that it can no longer follow the variation of voltage X but instead discharges (chain line Y of Fig.1) at a constant rate set by a rheostat 25. The amplifier 31 thus continues to receive a constant deceleration signal sufficiently large to maintain the transistor 37 inconduction and hold off the brake. With the braking reduced the wheel begins to accelerate again (point B Fig.1) towards the vehicle speed Z. At a time D the voltage X once again becomes equal to the voltage Y on the capacitor 30 and thereafter capacitor 30 begins to recharge. The input to amplifier 31 is thus reversed (indicating acceleration) and transistor 37 is cut off to restore the braking. In a second embodiment Fig.3 (not shown) parts of the circuit of Fig.2 are repeated to respond to negative values so that tractive effort is reduced if wheel acceleration becomes excessive. In a modification Fig.4 (not shown) the voltage Y on the capacitor 30 is directly compared with the speed voltage X by a differential amplifier 65. This is arranged to restore the braking or tractive effort when X and Y are equal. Means may be provided to restore braking after a predetermined time protecting against failure of the system and to prevent operation of the system at very low speeds e.g. during shunting of railway vehicles.

Abstract: 915,269. Control of A.C. motors. ENGLISH ELECTRIC CO. Ltd. Feb. 26, 1959 [Feb. 27, 1958], No. 6450/58. Class 38 (3). A winding operation is initiated when a control member is moved to operate one or other of the stator contactors 12, 13, for an induction motor 10, and, at the same time, contacts 29 are closed to energize a relay 28 whereby contacts 20 are closed and contacts 23, 24, are opened. A transducer 19 is then energized by a current transformer 22 in accordance with the stator current of the motor, and a rotor resistance 14 is reduced to increase the motor torque. An increase in the energization of the transducer 19 reduces the effort exerted by mechanical brakes 15 upon the motor, the brakes being released by the admission of fluid to a cylinder 17 having a control valve 18 which is, in turn, operated by the transducer. As the brakes begin to slip and the winding engine breaks away from rest, a motion-responsive relay 32 opens its contacts 30 to de-energize relay 28, so causing the current transformer to be short circuited and disconnecting the transducer from the transformer circuit. De-energization of the relay 28 also connects the transducer to a further brake control device 25 so as to release the brakes completely. Temporary de-energization of the transducer is prevented when changing from one supply circuit to the other, a rectifier 21 preventing interaction between the two circuits whilst they are in parallel. As the end-of-wind positions are approached, limit switch 33 is opened to de-energize the transducer and re-apply the brakes. In a modification, the control device 25 varies the braking effort in accordance with the deviation of motor speed from a reference value, so tending to reduce the deviation. Specification 863,262 is referred to.
