Title: Improvements in apparatus for stopping or retarding colliery corves and the like
IPC: B61K7/00
Filed: 1921-10-05
Abstract: 191,147. Robson, R. W. Oct. 5, 1921. Arresting-grips or friction apparatus on permanent way. - In railway vehicle braking apparatus comprising a tiltable bar or rail mounted on the permanent way adapted frictionally to engage the wheels of the vehicle under the influence of the weight of the vehicle, the tiltable bar carries a track rail section which is interposed in and in alignment with, the adjacent track rails. The bars g interposed between sections b of the usual track rails and hinged to the track at d carry the rail section h and a brake member j, which engages the sides of the vehicle wheels when these run on the section h. The braking faction is controlled by cams on shafts m which may be connected by levers o and rods p to the piston r of a fluid-pressure cylinder q. With the cams in the lowered position the weight of the vehicle is fully effective for braking. By the admission of fluid behind the piston r the cams are raised and according to the degree of pressure in the cylinder the weight of the vehicle is counteracted to a greater or less extent so that any desired degree of braking effect or none is obtained. The braking effect may be increased by connecting the cams to the bars g and admitting pressure fluid in front of tha piston r so as to force the bars downwardly. Springs may be inserted between the bars and the track for returning them to normal position after passage of the vehicle. The apparatus may be automatically controlled as by an approaching vehicle pressing down a valve and thereby releasing the brakes applied to a preceding vehicle.

Title: Improvements in superconductor circuits
IPC: G06F7/38
Filed: 1959-07-31
Abstract: 887,113. Superconductive circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 31, 1959 [Oct. 31, 1958], No. 26298/59. Class 40 (9). [Also in Group XIX] Cryotrons are used in adders for adding three binary digits and for adding two decimal digits. A number of cryotron elements are combined in a film of superconductive material. Adder for three binary digits.-Cryotron assemblies S1 S2, S3 are driven resistive respectively by one, two or three signals on conductors A, B, C. The signals on these conductors represent 1 and a signal on the C conductor represents a carry 1. A reset pulse is applied to terminal R to drive cryotrons K4, K5, K6 resistive. With no signals on A, B, C, representing three digits 0, 0, 0, current from a source Is flows through elements S3, S2, S1 in series to " sum " output terminal 12 representing 0. When the A, B, C signals drive one of the assemblies S1 S2, S3 resistive, the current from Is is diverted from junction points 28, 26, 24 through cryotrons K3, K2, K1, &c. to the appropriate " sum " terminal 12 or 14. Current from sources Ic is diverted from the " carry 0 " terminal at 20 to the " carry 1 " terminal 22 by cryotron K9 or K10 when assembly S2, or S3 goes resistive. An equivalent circuit, Fig. 2, is constructed from strips of superconductive film material. Where two conductors cross at a shaded area, the narrow conductor is of " hard " superconductive material with a high critical magnetic field and is used to control the wide conductor which at this part is of " soft " material with a low critical field. Adder for two decimal digits.-Leads a1 to a9, b1 to b9, marking two decimal digits, are commoned to 19 cryotron assemblies 1S to 19S. The adder is cleared as before by a reset pulse on terminal Ra. Two digit signals may drive resistive more than one of the assemblies but current from ISa is diverted to one of the sum output terminals D0 to D9 by the first resistive assembly encountered. For any less than 10, the sum circuit from current sources ISa includes the control coil of cryotron K20 which blocks the carry current from source Ica. The carry current is shunted to ground by cryotron K22. For any sum of 10 or more, shunt cryotron K22 is resistive and cryotron K20 conducts to produce a carry signal on terminal C1. Cryotron assemblies.-The assembly 6S for the sum 6 is shown in Fig. 3A. As shown, the element is resistive for any combination of two digits and possibly a carry digit which totals 6. Specifications 809,205 and 862,178 are referred to.
