Title: Improvements in railway track circuits
IPC: B61L1/18
Filed: 1957-04-25
Abstract: 821,373. Railway signalling track circuits. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. April 25, 1957 [June 1, 1956], No. 13197/57. Class 105. For the protection of railway-signalling track circuits from stray alternating current the track circuit feeds a system comprising two series rectifiers 9, 10 and two series condensers 12, 11 the condenser 12 and rectifier 10 being paralleled with a resistance 13 whereby the condensers are charged at different rates on each proper halfcycle and on the next half-cycle they discharge through two separate windings of the track relay which attracts its armature only if the fluxes are balanced and in opposition. Only for track circuit input feed pulses of the correct rate, e.g. two pulses a second, will the condensers be so charged and discharged as to give the balanced fluxes. These track-circuit input pulses are given by a uni-directional-pulse generator 7. The opposing balanced fluxes are directed to a third limb to act additively on the relay armature.

Title: Improvements in static electrical converter stations
IPC: H02M1/14
Filed: 1966-03-25
Abstract: 1,132,953. Converting. ALLMANNA SVEN SKA ELEKTRISKA A.B. 25 March, 1966 [27 March, 1965], No. 13254/66. Heading H2F. A static converter station, particularly for high-voltage transmission, has on its A.C. side an LCR filter of which part can be by-passed by a switch controlled by the operating conditions of the converter, e.g. pulse number or harmonic content. Filters associated with two series bridges giving 12-pulse operation may thus be adjusted if failure of one bridge requires the converter to continue in 6-pulse operation. Also if the filter is detuned with ageing or temperature its resistance can be increased to limit the current. In one form (Fig. 1, not shown) four filters containing L, C and R in series and tuned to different harmonics have their resistors capable of being shorted by relay contacts controlled by the converters. In another form (Fig. 2, not shown) the contacts progressively short out sections of the resistor.

Title: Improvements in or relating to clutches for winding or like operations
Inventor: SCHMID AUGUST
IPC: F16D7/02
Filed: 1951-06-06
Abstract: 700,025. Friction clutches. STANIOLFABRIK BURGDORF AKT.-GES. June 6, 1951. No. 13436/51. Class 80 (2) A clutch for use in winding rolls and like operations comprises a spring-loaded friction clutch, characterized by the provision of inclined surfaces in a connection interposed between a spring-loaded friction plate and its shaft, preferably with balls operative between the said inclined surfaces, for keeping the torsional moment constant upon alteration of the coefficient of friction, and a control device for controlling the contact pressure of the friction plate in relation to the sizeof a wound roll or the like. As shown, the clutch consists of driving and driven shafts 1, 2 with friction members 4, 5 thereon, the driving member 4 being rigidly secured to the shaft 1 and the driven member 5 being, to a limited extent, rotatable and axially slidable upon the driven shaft; the driven member 5 carries a ring 9 in which are grooves having inclined surfaces 7, co-operating with balls 6 similarly cooperating with inclined surfaces in a ring 10, pivoted on the driven shaft 2. Relative.rotation between the rings 9, 10 displaces the clutch member 5 axially so that variation of the coefficient of friction, and hence of the torque transmitted between the clutch members, due to heating, is automatically compensated; the connecting means 6, 9, 10, &c. allows some universal movement of the driven clutch member to compensate for unequal wear of the friction surfaces. The clutch members are drivingly urged into engagement by a spring-urged roll 21, in a cylindrical member 24 secured to and rotated with a control shaft 23, engaging a circular camface 20 in a pivotable lever 14 integral with arms 15, above and below the driven shaft, abutting pins 17 in a carrier spider 16. Pins 18 on the carrier spider engage one race of a thrust bearing 19, the other race of which abuts the driven clutch member 5. The spring force acting on the roll 21 is thus transmitted through members 14, 15, 17, 16, 18, 19 to the driven clutch member 5, and as the shaft 23 is rotated to change the point of application of the spring force to the cam face 20, so the force tending to engage the clutch members 4; 5 is varied. Blades 38 on the driving clutch member propel air through apertures 36, 37 to cool the clutch.- The face of the driving friction member is preferably made from nitralloy steel. The axial distance between the clutch members 4, 5 can be adjusted to compensate for wear of their friction facings by means of an exteriorly threaded sleeve 33 screwed into the converter housing. The control shaft 23 is rotated to control the torque of the output shaft by a linkage actuated by an arm gauging the radius of the wound roll &c.

[Also in Group IX] In a process for obtaining a design on velvet, plush or imitation fur fabric, in which the pile is formed by a mixture of two different types of fibres, the fabric is subjected to an operation to increase or reduce the length of the fibres of one type and at least one shaving of the fibres is made. In one embodiment. Fig. 2, the fibres A, B are shaved at uniform height, Fig. 2 (first drawing) and the fabric is treated by uncurling or stretching to raise the fibres A. The fabric is then cut to the form shown in Fig. 2 (third drawing) so that hollows of the profile pass below the surface of the fibres B. Preferably the fibres A, B are of different colours. Alternatively a wavy profile may be cut to obtain colour graduations. In a second embodiment, Fig. 3, the fabric is cut to crenellated form, Fig. 3 (first drawing) and is treated to raise the fibres A. The surface m-n is recut at uniform height to obtain two colour bands, Fig 3 (third drawing). Methods of increasing or decreasing the height of one type of the fibres include thermal or chemical shrinking, uncrimping, stretching at a defined temperature and under a defined force and unwinding a thread of one type of fibre helically wound around a thread of the second type. A design may be produced by having a number of different types and colours of fibres and performing a succession of the abovedescribed operations.
