Title: Improvements relating to the operation of a polyphase electric motor from a single phase source
IPC: H02K17/08
Filed: 1945-07-24
Abstract: 632,918. Induction machines; phase-changing. BRITISH THOMSON-HOUSTON CO., Ltd., MAGGS, A. H., and CHOUDHURY, S. U. A. July 24, 1945, No. 18930. [Classes 35 and 38 (ii)] [Also in Group XXXVII] Suitable operating characteristics for a three-phase induction motor, which is supplied through terminals 8 and 9 from single-phase mains 1, 2, are afforded by means of a capacitor 6 and a saturable ironcored reactor 7, which are connected in parallel across motor terminals 8 and 10. The reactance of the combination of the elements 6, 7, varies with the applied voltage, the reactor being designed to become saturated at a voltage substantially equal to that obtaining across terminals 8, 10, when the motor is running at normal speed and load. The winding of the induction motor may be delta-connected (Fig. 2, not shown), or star-connected for starting and delta-connected for running (Figs. 3, 4, not shown). Reversal is obtained by connecting the capacitor and reactor to a different pair of motor terminals, such as 9 and 10 in Fig. 1. The number of turns of the motor phase winding 4 may be made smaller than that of the windings 3 and 5. In this case reversal is obtained by connecting another pair of motor terminals to the supply-lines. Specification 630,007 is referred to.

Title: Improvements in digital data handling systems
IPC: H04L1/00
Filed: 1964-05-08
Abstract: 1,057,985. Error correction. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 8, 1964 [May 13, 1963], No. 19347/64. Heading G4C. A digital data word comprising information and parity bits in accordance with a Hamming single error correcting code is assembled in parallel form from bits occurring on a number of separate lines each of which supplies a serial pair of bits, double errors being corrected on the assumption that both bits in error occurred on the same line. In the particular embodiment, a 16-bit word comprising 11 information bits and 5 parity bits is read from a set of eight magnetic disc stores and assembled in parallel form. EXCLUSIVE-OR circuitry performs parity checks to produce error signals E0, E1, E2, E4, E8 (all " zero " in the absence of errors). If E0, which relates to the whole word, is " one," there is assumed to be a single error (rather than 3, 5 or &c.) and the error signals E1, E2, E4 are allowed by gating circuitry (Fig. 8, not shown) to constitute the input to one of two binary to decimal decoders (no details given) depending on the value of signal E8. The selected decoder produces an output on one of eight lines leading to EXCLUSIVE- OR gates to correct the bit in error. If both signals E0 and E8 are " zero", there is an uncorrectable double (or strictly, even) error and an alarm signal is generated. If signals E0 and E8 are " zero " and " one " respectively, both binary to decimal decoders receive signals derived from the error signals E1, E2, E4 (see Figs. 8, 10, not shown) by EXCLUSIVE-OR gates and two errors are corrected. Thus when a double error occurs and it is consistent with the results of the parity checks to assume that both bits in error came from the same disc, corrections are made on these assumptions, whereas when only the first assumption is consistent, the errors are declared uncorrectable.

Filed: 1919-08-06
Abstract: 151,425. Fowler & Co., J., and Royston, M. H. Aug. 6, 1919. Ploughs.-To facilitate the tipping of an antibalance plough, the bottom stretcher d of the plough carriage or middle frame is provided with arms e extending longitudinally of the plough frame and carrying rollers f adapted to engage inclined guides g on the frame. On reversing the pull on the stretcher the one roller f is moved into engagement with its guide and travels along it tilting the middle frame until the second roller f is brought up against the end of its guide, the stretcher then having accomplished half its movement along the frame. The middle frame and the plough frame are thus held rigidly together and the plough may be tipped about the axis of its main carrying wheels. In the working position the rollers fare freed from the guides and the middle frame may oscillate freely about the wheel axis. Specifications 3861/86 and 4735/99 are referred to.

INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts- Ges.; 2, Friedrich Karl Ufer, Berlin.) July 8, 1931, No. 19689. Convention date, July 9, 1930. [Class 38 (iii).] In a system, more particularly for ship propulsion, in which motors M1, M2 are connected in series with one or more generators G, and the speed regulation is effected by motor field or Ward Leonard control, according to whether the motors are running at dissimilar or equal speeds, main controllers 7, 8, associated with the motors regulate the generator fields, and an auxiliary controller 14, coupled with the main controllers through a mechanical or electrical differential 13, regulates the motor fields. When the controllers 7, 8 occupy the same positions, the motors are fully excited, but when they are in dissimilar positions the field of the motor which must have the smaller torque and speed is weakened. The controllers 7, 8 follow guide controllers 3, 4 on the bridge. The controller 14 inserts resistance in the generator fields at the same time as it reduces a motor field, and thereby limits the current. The direction of rotation is determined by motor field reversing contactors under the control of the controllers 3, 4, and the main controllers 7, 8 move in one direction for forward and reverse operation. The generator G- has shunt, series, and separately excited fields differentially arranged, so that when the guide controllers are moved from a forward to a reverse position, the voltage of the generator is temporarily reversed, and then builds up again in the original direction, as the motors speed up in the opposite direction.
