Title: Improvements in or relating to control systems for electric motors
IPC: B60L15/04
Filed: 1928-11-23
Abstract: 301,464. Associated Electrical Industries, Ltd., (formerly Metropolitan- Vickers Electrical Co., Ltd.), (Assignees of Clarke, J. A.). Nov. 30, 1927, Convention date]. Drawings to Specification. Master control systems; series-parallel systems.-In a system for the series-parallel control of railway motors, for example four motors arranged in two pairs, a master controller by successive notching movements determines the setting of an electro-pneumatically actuated drum fitted with cams to close grouping switches, and also determines the closure of electromagnetically actuated contactors which include grouping contactors and resistance contactors. The transition from series to parallel grouping takes place through a number of intermediate positions of the cam-drum in the course of which one pair of motors is temporarily short-circuited and separated from the other pair which remains connected to the line, and the resistances are divided and re-inserted as the two pairs are recombined in parallel. The contactors are electrically interlocked so that when the motors are changed back from parallel to series, a transition of open-circuit type is obtained. Isolating switches are arranged so as to cut-out either pair of motors, leaving the other pair connected as in the parallel grouping. Electrical interlocks are provided between the cam-operated switches and the electromagnetic contactors. The adaptation of the control system to multiple-unit working is indicated.

Title: A Method of and a Machine for Straightening Elongate Metallic Materials.
IPC: B21D1/02
Filed: 1967-07-27
Abstract: 1,179,948. Straightening. SCHLOEMANN A.G. 27 July, 1967 [28 July, 1966], No. 34589/67. Heading B3E. In a method of straightening elongate metallic materials using an upper and a lower set of rolls, the lower set of which may be moved relatively to the upper set in a plane parallel to the direction of movement of the material to be straightened, the rolls of the lower set of rolls are selectively moved relatively to the upper set so that the planes normal to said plane containing the roll axes of the lower set do not coincide with the corresponding planes of the upper set. The lower back-up and straightening rolls 5, 6 are mounted in a crossmember 2b which also includes a shaft 10 driving a worm 11 meshing with a worm-wheel 12. The worm-wheel is secured to a threaded sleeve 13 and rotation thereof causes horizontal movement of the cross-member 2b along a shaft 14, which is secured to the cross-member by adjusting spring 16. Hence the distance X can be varied thereby giving an effect similar to varying the roll pitch. The rolls 6 and back. up rolls 5 are mounted in bearings 20, 24 respectively, which are secured to racks 21, 25 respectively for horizontal shifting of the individual rolls. A motor 28 drives a shaft 27 on which are mounted pinions 26 engaging the racks 25 and a pinion 23 meshing with pinions 22, 22a engaging the rack 21. The bearings 20, 24 are guided in guides 29, 30 respectively. The upper rolls are similarly adjustable and additionally the cross-member 2a is vertically adjustable. The distance X may be varied automatically according to the thickness of the material by a device preceding the straightening machine, signals from the device being passed to a computer which controls the drive of the worm shaft 10.
