Title: Improvements relating to the production of electric conductors and circuit components
IPC: H03K4/86
Filed: 1948-11-05
Abstract: 700,452. Multiplying cables. STRONG, H. V., and EISLER, P. Nov. 7, 1949 [Nov. 5 1948], No. 25995/48. Class 36.  A flat strip cable comprises a primary layer of insulation having a plurality of separate flat section conductors each of substantially V form secured thereto with their axes transverse to the length of the strip, their two limbs on opposite faces of the strip and so spaced longitudinally of the strip as to form a plurality of groups, each of which groups corresponds to a unit set of terminals of the equipment to be connected, and in each of which groups the end of each conductor overlaps the beginning of the corresponding conductor of the next group to which it is electrically and mechanically bonded to form a series of zig-zag conductors having joints on a line extending longitudinally of the strip. The conductors may be applied to the insulating layer by the printed circuit methods as described, for example, in Specifications 639,111, 639,178, 639,179 and 639,658, or they may be stamped from metal foil, (Fig. 1). Slots 5 are punched out of a sheet of foil, leaving conductors 1 joined together by margins 6 and bridge pieces 7. A strip 8 of insulating material is pressed on to one or both sides of the foil. The strip 8 is narrower than the foil and has central slots 9a which leave exposed the centre parts 4, 7 of the foil. Bridge pieces 7 are then removed and the assembly folded over an insulating strip 10 (Fig. 2) and secured by adhesives. The margins 6 are then removed. The ends 2, 3 of the conductors 1 are accurately superposed so that connection can be made as by riveting between the termination of one conductor of one group and the beginning of the corresponding conductor of the next group, thus forming a cable having four conductors to a group. Cables having any number of conductors to a group may be made by this method. Connection tags 12 may be secured to exposed parts 2, 3, 4 of each conductor 1, or the exposed parts may themselves form switch contacts. Strips may be made in which pairs of conductors are given a " twist in order to eliminate cross talk (Fig. 8). Metal foil 30 is punched out as shown, leaving margins 32 and bridge pieces 33, 36 intact. After applying the insulation and folding as before these portions are removed, so that each pair of conductors is, in effect, transposed. The insulating strips used for these cables may have metal incorporated therein for screening purposes. Specification. 644,565 also is referred to.

Title: Improvements relating to automatic slack-adjusting mechanisms for braking apparatus on railway and like vehicles
IPC: B61H15/00
Filed: 1948-10-06
Abstract: 647,046. Brake slack adjusting mechanism. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and BRACKENBURY, A. G. Oct. 6, 1948, No. 26034. [Class 103 (i)] In brake transmission gear of the type in which each brake rod is provided with relatively movable members 9, 10 by the adjustment of which the effective length of the rod may be varied to take up slack, the adjustment of both these members is synchronously effected by a common operating mechanism actuated by the movement of a portion of the rigging transmitting braking effort to both the brake rods. As shown, the screwed rods 7, 8 are geared by bevel wheels 11, 13 and 12, 14 to a transverse shaft 18. When the shaft 1 is turned and cranks 2 and 3 move to apply the brakes, a casing 21 carrying two ratchets 20, 22 is made to move with the shaft 1 by means of a pin 26 engaging a boss 24, so that the ratchet 20 slips over a tooth on a ratchet-wheel 19 secured to the shaft 18 if the movement is sufficient. When the brakes are released, the return movement of the ratchets 20 and 22 rotate the shaft 18 so that an equal slack adjustment is applied to each brake rod. The operation of the ratchet mechanism is similar to that described in Specification 466,792.
Patent GB-600981-A (GB)
Title: Improvements in or relating to d.c. electric motor control systems
IPC: B60L7/12
Filed: 1945-10-08
Abstract: 600,981. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and TURRALL, J. C. Oct. 8, 1945, No. 26178. [Class 38 (iii)] Regeneration.-When a D.C. motor with variable shunt excitation is running with reduced excitation, the motor controller is moved to its '' off " position and quickly returned, a relay subject to armature current prevents the exciting current from rising to cause regeneration. The relay has an operating coil connected across starting resistance in the armature circuit and may have another controlled by the controller and its contacts control shunt field resistance contactors. In Fig. 1, movement of a trolley-bus power controller 6 to its first step, to start the traction motor from rest, energizes coils 10c, 12c and 20c to close the line switches 10 and 12 for the motor armature 1 and series field 2 and the contactor 20 for the shunt field 3. The P.D. across the starting resistance 4 is enough to energize coil 28c1 and close the relay, which maintains itself by its coil 28c2 through its contacts 28 No 2 and the controller 6 and which completes a circuit by its contacts 28 No 1, through the controller 6, for the coils 21c-23c of the shunt field resistance contactors 21-23 so that the motor starts on full field. Further movement of controller 6 energizes the coils 15c-18c of contactors 15-18 to cut out the starting resistance 4 in steps and then deenergizes coils 21c-23c to insert the shunt field resistance 5 in steps. Return movement will re-energize coils 23c-21c in that order and so strengthen the excitation to cause regenerative braking. If the controller, however, be returned to the off position-de-energizing relay coil 28c2-and then quickly moved forward again, the relay coil 28c1 will not lift the relay on the first few steps unless the motor armature current is high enough to indicate that the excitation can be strengthened without causing regeneration. Field contactors 21c-23c will accordingly not be energized. The current necessary to lift the relay will vary from step, i.e. according to the starting resistance in circuit. The controller 6 can, however, be moved to its final position to parallel contacts 28 No 2 and lift the relay by coil 28c2 ; return movement will then close the contactors 23-21 for regenerative braking. Rheostatic braking can be introduced by moving the brake controller 7-electrically interlocked with controller 6-to energize coil 19c of brake contactor 19 which de-energizes line switch 12, connects armature 1, series field 2 and part of resistance 4 in a closed circuit and lifts the relay by coil 28c through contacts 19 No so that further movement of controller 7 will close the field contactors 21 and 22. Excess voltage while the power controller 6 is in an on position will cause over-voltage relay 26 to energize coils 19c and 28c2 by contacts 26 No and cause rheostatic braking.

Abstract: 908,159. Liquefaction of gases and separation of mixtures thereof. LINDE'S EISMASCHINEN A.G. GES. FUR. July 28, 1960 [July 29, 1959], No. 26277/60. Class 8(2). The cold requirements of a gas liquefaction or a gas mixture separation process are met by freely expanding gas from above its critical pressure to below it in valves 7, 8, Fig. 1, discharging into a liquefying chamber 9, withdrawing uncondensed gas through a duct 19, warming it in exchangers 5, 6 traversed by incoming high pressure gas and expanding in a turbine 3. The resulting cold gas is used in exchangers 2, 4 to coal incoming gas and is fed to the inlet of a compressor 1 which compresses it together with make-up gas from a valued duct 22 to above the critical pressure. Product liquefied gas is withdrawn from chamber 9 through a duct 20. In a modification the condensed portion of the working gas serves to liquefy a gas from a feed duct 24, Fig. 2 having been cooled in exchangers 27, 28, in the working gas circuit prior to traversing a liquefying coil 31. The soliquefied gas is expanded in a valve 32 and is separated in a chamber 34; the uncondensed portion being used in an exchanger 29 to cool a portion of the feed gas in a duct 26. In a further modification the liquefied portion of the working gas is expanded in a valve 38, Fig. 3, which discharges into the high pressure stage 39 of a rectification column, the feed and discharge ducts of which are omitted, and make-up gas is withdrawn from column 39 through a duct 41, a heat exchanger 47 and exchangers 4, 2 which discharge into the inlet of compressor 1. In a further modification a high boiling gas fraction withdrawn from the low pressure column is compressed, cooled in exchangers 27, 28 and at least partly condensed in coil 31, and expanded back into said low pressure column.

Title: Fractional extraction of mineral oils
IPC: C10G21/20
Filed: 1930-09-05
Abstract: Crude oils, or distillates, or residues, containing paraffinic and naphthenic hydrocarbons are treated with nitrobenzene, nitrotoluene, nitronaphthalene, other suitable nitro aromatic hydrocarbon, or mixtures thereof to extract a fraction or fractions richer in naphthenes and leave a fraction or fractions richer in paraffins. Wax may be separated before or after the treatment.  The process is especially applicable for making lubricants of relatively high viscosity and low s.g. from mixed base crude oils or residues.  The production of lubricating stock of s.g. below 0,910 and of viscosity greater than 150 sec. Saybolt at 210 DEG  F. from a crude petroleum residuum of s.g. above 0,928 and of 150 DEG  viscosity is particularly referred to.  The oil and nitrobenzene may be agitated together cold, or the mixture may be heated until solution takes place and the solution be cooled.  In an example, 2 litres of nitrobenzene are heated to 60 DEG  C. with 1 litre of a high-viscosity wax-bearing distillate of Texas mixed base oil, and the solution cooled to 10 DEG  C.  The lower or nitrobenzene layer is drawn off and freed from nitrobenzene by steam under reduced pressure.  The semi-solid upper layer is retreated and separated twice more, and the final upper layer is diluted with naphtha and chilled to -20 DEG  C. to separate wax.  The naphtha is removed by distillation.
