Title: Improvements relating to double wire mechanical control systems for operating railway points or signals
IPC: B61L5/02
Filed: 1955-04-21
Abstract: 816,137. Railway points or signal double wire mechanical control systems; interlocking. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and DENNISON, H. F. April 11, 1956 [April 21, 1955], No. 11542/55. Class 105. In a double-wire railway points or signal mechanical control system having a control lever 1 at a control location such as a signal cabin, coupled to the points or signal operating mechanism 17 by a pair of transmission wires 8, 9 capable of reversible movement under control of the lever 1, there are provided a second control lever 31, located for example near the points location for convenience during a shunting operation, and manually operable to operate the points operating mechanism by the same transmission wires 8, 9 and means for preventing the operation of either lever 1, 31, unless the other is in its normal unoperated position. As shown, a coupling device 13 couples the transmission wires 8, 9 to the points operating mechanism 17 and comprises two levers 20, 24 carrying pulley wheels 14, 23 around which loops 12, 26 of the wires 9, 8 respectively run, the loops being formed between stationary pulley wheels 10, 11 and 27, 28 respectively so that as either the lever 1 or 31 is operated loop 12 is shortened and loop 26 is lengthened to rotate the levers 20, 24 about their pivots 21, 25 in opposite directions thereby moving longitudinally the wire 18 connected between their free ends and passed around the stationary pulley wheels 16, 19 and the mechanism 17 to operate this latter. Each lever 1, 31 is mechanically interlocked with a miniature lever 2, 32 provided with a lock 3, 33 in which a key 4, 34 must be turned in order to unlock the miniature lever to enable it to free the lever 1, 31. Once the lever 2, 32 has been operated the key cannot be removed from the lock until that lever is again in its normal unoperated position. Either of these keys 4, 34 can only be released from its electric key transmitter and receiver instrument 37, 35 at the respective control lever locations when the other key has been replaced in its instrument and turned so that it is impossible for more than one of the levers 2, 32 to be unlocked at any one time and for the two control levers to be in the operative positions at the same time.

IPC: H01M10/04
Abstract: 115,635. Hawkins, H. S. May 2, 1917, [Convention date]. Drawings to Specification. Separators; supports for electrodes; absorbents. -The electrodes, which rest on ribs integral with the container are spaced from one another and from the cell by a filling of porous carbon obtained by carbonizing sugar. In carrying out the process, after the electrodes have been placed in the cell the latter is filled with granulated cane, beet, or other sugar and baked from three to six hours at from 380 to 410 F. Separators of paper or wood may be inserted with the sugar between the electrodes, these separators being also carbonized by the baking process. If the cell is of rubber or other material incapable of withstanding heat, the electrodes and sugar are wrapped in paper and baked in a glass cell. The whole is then removed, the carbonized paper being stripped off and the electrodes with the spongy carbon transferred to the rubber &c. container. The spongy carbon is stated to be non-conducting. The electrodes may be one-sixteenth of an inch thick, or less.

Title: An improved speed regulating mechanism for wire winding and like machines
IPC: B65H54/28
Filed: 1932-04-23
Abstract: 400,926. Wire and like winding- machines. RICHARDS, S. H., 10, Patten Road, Wandsworth Common, London. April 23, 1932, No. 11765. [Class 120 (ii).] In wire-winding and like machines, means are provided, in combination with the traverse guide for laying the wire on the reel, to reduce the rate of rotation of said reel each time the guide completes a traverse along the winding reel. The wire is laid upon a reel a by a guide b mounted on an arm c adjustably pivoted at d in a slot e, and connected by an adjustable link g to an arm h reciprocated by a cam i. The link g is movable along the arm c to adjust the throw of the guide b. The shaft j carrying the cam i is rotated from the reel shaft k by worm gears m, n. The shaft k is driven from the shaft r by oppositely coned pulleys o, p and a belt q which is adjustable along the pulleys by a belt fork 5, pivoted at 6 in a slot 7. The belt fork is moved by means comprising a pulley 9 around which passes a cord 10 connected to two drums 11, 12 of different diameter, on a shaft 13, carrying a ratchet wheel 14, which is rotated by a pawl 16 connected by a lever 21 with a cam 20 on the shaft j. Each reciprocation of the guide b by the cam i corresponds to a single rotation of the cam 20, which being double causes two movements of the wheel 14. The turning of the wheel 14 shortens the length of cord 10 between the shaft 13 and pulley 9 so that the fork arm 5 is drawn against the spring 23 towards the shaft 13. A pawl 17 adjusted by a screw 18 and bell crank lever 19 limits the stroke of the pawl 16. At the completion of a winding the pawls 16, 17 are disengaged from the wheel 14 which is wound back by a handle 15 to the starting position. The shaft r is driven by oppositely coned pulleys s, t connected by a belt 2 from a shaft w carrying fast and loose pulleys x, y. The position of the belt 2 on the pulleys s, t is adjusted by the screw 3 and handwheel 4 and determines the initial winding speed. The stepped pulleys u, v are for use in the wire drawing operation.

Title: Improvements in and relating to metal-glass seals
IPC: H01J5/26
Filed: 1946-04-17
Abstract: 610,867. Metal-to-glass seals. PHILIPS LAMPS, Ltd. April 17, 1946, No. 11784. Convention date, Aug. 21, 1941. [Class 36] A metal-to-glass seal is formed by pressing the end of a metal body through a pre-heated glass sheet, the metal body being heated, as by high-frequency induction, sufficiently to melt the contacting portion of the glass. As shown in Fig. 3, the severed disc-portion 2b of the glass forms a closure-member for the metal body 1, the separated portion 2a being removed after cooling. Fig. 5 shows a modification in which the flanged edge 7a of an outer glass sleeve 6 is sealed to a tubular metal body 5 by pressing the latter through the pre-closed end of the sleeve. In this case, the part 7b of the glass is removed after cooling. The metal surface required to adhere to the glass may be pre-coated with enamel and the other surface coated with material, such as graphite, to prevent adhesion. Porous glass may be used, and in all cases the relative coefficients of expansion of the metal and glass are chosen according to the location of the seal on the inner or outer surface of the metal body. When the relative thermal expansion of the metal and glass are substantially different, as in the case of a copper body 12, Fig. 7, and a lead-glass closure 13, a band 15 of high tensile strength may be fitted around the lower end of the metal body.

Title: Process for the manufacture of ethylene oxide
Filed: 1951-05-22
Abstract: In the catalytic oxidation of ethylene with oxygen to ethylene oxide, helium is added as diluent.  An ethylenic feed such as cracked gas, together with oxygen and helium to give approximately 5 per cent ethylene and 6 per cent oxygen in the mixture may be fed through a multi-tubular reactor containing silver at 220-350 DEG  C. and 1-20 atm.  Ethylene oxide is absorbed, e.g. in water, CO2 then removed, e.g. in ethanolamine, and the residual gas recycled.  The oxygen may be obtained by air fractionation and added to the recycle gas.  Part of the recycle stream is purged to remove inert gases, helium being recovered by compressing, condensing with the aid of nitrogen from the air fractionation, and stripping.  Helium may also be stripped from the solvents used in the absorption.
