Title: Improvements in or relating to operating mechanism for electric circuit breakers
IPC: H01H3/32
Filed: 1939-10-11
Abstract: 535,032. Automatic circuit - breakers. GENERAL ELECTRIC CO., Ltd., HARKUS, G. N., and GARRARD, C. J. O. Oct. 11, 1939, No. 27658. [Class 38 (v)] When the handlelever 1 is rotated from the upper, open position, a roller 18 on a spring-urged, gravity lever 12 pivoted to lever 1 at 1a, rides off a fixed ramp' 19 and is free to rotate clockwise in the tripping direction. but provided the handle is moved reliably, the lever 10 remains behind the handle and tripping does not occur. In the closed position a fixed stop 21 arrests the lever 10. The intermediate position shows the parts when tripping occurs due to too low a handle-speed, a tail 13 having rotated a lever 5 about its pivot 7 on the handle, so releasing a part 3 in the transmission. The operation may be adjusted by varying the position of the weight or the point of attachment to lever 10 of the spring 15 which alternatively may be arranged to oppose, instead of assist, the weight. The Provisional Specification states also that a balanced lever may be pivoted cn the handle-axis and adjustably spring biased in the closing direction, the lever being arranged to overtake the handle and trip a catch.

Title: Error detection and correction circuits
IPC: H03M13/19
Filed: 1972-06-14
Abstract: 1363586 Digital data error detection and correction INTERNATIONAL BUSINESS MACHINES CORP 14 June 1972 [26 June 1971] 27710/72 Heading G4A A modified Hamming code is used to detect multiple errors, and to correct single errors, in words, e.g. read from a data store. A modified Hamming code is defined as a Hamming code in which each data bit is related to an odd number of check bits, one half of the data bits in an information word are related to an even number of check bits of one half of the check bits and to an odd number of check bits of the other half of the check bits, the other half of the data bits in an information word are related to an odd number of check bits in said one half of the check bits and to an even number of check bits in said other half of the check bits, and the data bits of each byte are all uniquely related to the same half of the check bits. Each word has 64 data bits Di and eight check bits Cj and the bits Di are passed to check bit generators RBG1 to regenerate the check bits (Gj). The check bits Gj are compared with the check bits Cj in a comparator 2 to produce eight syndrome signals, erroneous bits being indicated by a 1 syndrome. These pass to an error bit location circuit FBL3, to a circuit UGP4 which. finds out if the number of 1 syndromes is odd or even, and to a circuit FKF5 which indicates whether there are any errors. A circuit 6 sends a KBF signal when there is a correctable error (odd number of syndromes with binary 1) and a UKBF signal when the error is uncorrectable (even number of syndromes other than zero with binary 1). If the error is correctable, the data bits Di are corrected in circuit DBM7 to give Di<SP>1</SP>. A circuit 8 then forms a parity bit for each eight bits of Di<SP>1</SP>. In another embodiment (Fig. 3, not shown) a parity bit is shown which enables the corrected parity bits to be produced simultaneously with the corrected data bits.

Title: Braking apparatus for electrically propelled motor vehicles
IPC: H02P3/06
Filed: 1929-09-21
Abstract: 319,739. Spangler, L. Sept. 27, 1928, [Convention date]. Electric and magnetic.-In electricallypropelled vehicles wherein the motors are run as generators for braking, each motor or group of motors is connected in a separate circuit and the current in a pair of circuits acts oppositely on a magnet so as to effect the application of a mechanical brake to one axle or group of axles if the braking current associated with this axle or group fails or weakens. The braking current in the separate circuits of the motors 1, 2 passes through the coils 5, 6 of a magnet connected by gearing 7, 8 to a brake which is thus applied to the axle of one of the motors if the current in the circuit thereof fails or weakens. The gearing may be directly connected to the brake or it may bring into operation a source of power for applying it. Optical or acoustic indicating devices may be provided to indicate to the motorman the application of the mechanical brakes. Known arrangements in which the braking current and the supply current act oppositely upon a magnet whereby the supply current brings a mechanical brake into operation if the braking current fails are referred to.

Void [Abridged as open to inspection under Sect. 91 of the Acts, April 23, 1935]. [Class 10] Control means are provided in the transmission from a source of power 1 to the driven part 13 which, at preferably equal time periods, disconnect the driven part from the source of power and allow it to run by the momentum stored in it until again connected to the source of power. In the apparatus shown, the power source 1 drives through a clutch 2 and gearing a shaft 11 connected by a one-way clutch 12 to the shaft 14 of the driven member 13. The shaft 14 rotates, through further gearing, a shaft on which is mounted a cam 22 acting on the lever 24 of a band brake 26 encircling a brake disc 27 mounted on a shaft 28 which forms a part of the transmission between the power source 1 and the driven member 13. At periodic intervals the cam allows a spring 29 to move the lever so that the band brake stops the rotation of the transmission members. The member 13 continues to run in virtue of the momentum of the moving parts and owing to the provision of the one-way clutch 12, and the continued rotation of the cam 22 thereby produced causes it after a certain period to free the band brake and allow the power source 1 again to take up the drive. A slightly modified band brake mechanism, and a ratchet- and-pawl arresting mechanism, both operated by a cam are also described. The mechanism may be applied to advertising devices, flashing lights, periodically acting pumps, machine tools, and other apparatus where an intermittently acting power transmission is required.
