Title: Improvements in or relating to bridge contacts and fuse carriers for electric fuses
IPC: H01H85/044
Filed: 1937-06-18
Abstract: 492,997. Electric cut - outs. SYKES & DYSON, Ltd., SYKES, P., and GRIFFITH, F. J. June 18, 1937, No. 16950. [Class 38 (i)] In an electric cut-out, the insulating handle c carrying the fuse element e is provided with a transversely-extending integral depending block c<3> which has an opening extending through it housing two parallel asbestos or equivalent tubes d.

Title: Swab assemblies
IPC: E21B37/10
Filed: 1959-05-19
Abstract: 917,861. Wells. BORG-WARNER CORPORATION. May 19, 1959 [June 18, 1958 (2)], No. 17006/59. Class 85. [Also in Groups XXVI and XXVIII] A well swab comprises a mandrel 1, a head 2 connected thereto for the attachment of a wire or like line, a nose 6, attached to the lower end of the mandrel, and swab rubbers S slidable on the mandrel and arranged to seat upon the valve face 7 of the nose when the swab is being pulled up with its load of well fluid. The contacting ends of the rubbers fit fluid-tightly together. In Fig. 11, the swab rubbers S each comprise a tubular core 13 with a flared lower end 14, and a rubber body 15 moulded around the core but bonded thereto only at the lower part 15a. Reinforcements 16 of hair-pin like form are spaced circumferentially and are exposed to the casing wall T to reduce wear on the rubber. The loops of the hair-pins are held between the core 13 and a rigid thimble 18 and the free ends are bent inwardly at 16f. A comparatively rigid ring 17 encircles a waist formed by indentations in the reinforcements and acts as a fulcrum for the reinforcements whereby outward expanding movement of the upper part 15b of the swab tend to compress the lower part 15c of the swab, and vice versa. The swabs are made with clearance to descend freely in the well, but when the swabs are pulled up, the valve 7 closes on the seat 19, and the increased pressure between the cores 13 and the unbonded major lengths of the rubber bodies S tends to force the swabs against the wall T. The parts 15b yields under moderate pressure, but the parts 15c being held by the rings 17 and thimbles 18 require much more pressure to bring them into contact with the wall. The nose 6 releases excessive pressure due to too great an amount of well fluid above the swab, by a spring-pressed valve (not shown), the compression of the spring being so adjusted that the valve leaves its seat when the pressure becomes dangerous. Specification 917,862 is referred to.

Title: Control apparatus for electric ship propulsion
IPC: B63H23/24
Filed: 1924-07-16
Abstract: 219,682. British Thomson-Houston Co., Ltd., (Assignees of Stearns, R.). July 26, 1923, [Convention date]. Dynamos and motors combined for transmitting power.-In an electric ship propulsion system comprising a turbine 1, Fig. 1, generator 3 and motor 4, the motor circuits and the steam governor 2 are normally controlled by controllers 9, 20, 23 situated in the pilot house, but in an emergency can be controlled by controllers 10, 21 and lever 30 situated in the engine room. Current from a source 19 passes through a segment 22 of the controller 21 when it is in the " off " position to the controllers 9, 20, 23, the controller 9 operating reversing-switches 5, 6, and the controller 20 operating rotor-resistance shortening-switches 15, 16. The controller 23 determines the actuation of a reversible motor 32 which operates the lever 30 and a " follow-up " device 24 provided with contact segments 25, 26. This device 24 stops the motor 32 when it has moved the lever 30 to a position corresponding to the controller 23. Movement of the controller 22 from the " off " position renders the controllers 9, 20, 23 ineffective, and thereafter controls the switches 15, 16 and also makes the switches 5, 6 responsive to the controller 10. The lever 30 is connected to a gear 36, driven from the motor 32, by a worm 43 and a gear 44 carried in a member 40 pivoted to the lever 30 and spring biased to keep gears 36, 44 in mesh. The lever 30 can be operated in the engine room by moving the member 40 to disengage gears 36, 44, this movement also rocking a lever 61 to trip a switch 54 in the supply circuit to the controller 23, the switch 54 remaining open until closed by hand. A hand wheel 45 rotating the worm 43 serves for making fine adjustments of the lever 30. The controllers 9, 20, 23 are interlocked as shown in Fig. 2 by means of pivoted arms 47, 48 cooperating with cams 9<1>, 20<1>, 23<1>, carried by the controllers. By raising spring-biassed latches 51, 53 on the arms 47, 48, the controller 23 may be turned from the " off " position when the controller 20 is not in the off " position and may be advanced from the " Medium Steam " position when the controller 20 is not in the " Resistance Out " position.

Title: Improvements in or relating to chucks
IPC: B23B31/20
Filed: 1953-06-19
Abstract: 757,499. Chucks. HULL, H. S., and BAKER, R. J. June 10, 1954 [June 19, 1953], No. 17081/53. Class 83 (3). A chuck has a body with a number of axiallyspaced conical sockets and an assemblage of jaws to engage the sockets and comprising one or more sets of jaws, the jaws in each set being circumferentially spaced apart around the chuck axis and joined together by a continuous ring of rubber bonded thereto. The jaw assemblage of one embodiment comprises sets of jaws 10, 11 engaging a carrier ring 14 and resiliently connected thereto and to each other by rubber &c. rings 15. The body 17 has screwed thereto a member 21 having a conical socket 21a for engagement with the coned end 12 of the assemblage and has slidable axially therein a member 23 having a conical socket 24 for engagement with the coned end 13 of the assemblage. Member 23 is slid by a screwed ring 22 rotated by toothed wheel 32 via compound pinion 31. In another arrangement the member moves slidable pegs into a rubber &c. body abutting a further member carrying the conicalsocket engaging end 13. In yet another arrangement, member 21 is turned on threads on the chuck body to move the jaws radially, member 23 being integral with or fixed to the body. Each set of jaws 10, 11 may be bonded to a ring 15 to form a unit, two units being arranged back-to-back and abutting the ring 14. Where a single set of jaws is used, each jaw has axially-spaced inclined edges for engagement with the sockets.

Title: Improvements relating to the preparation of sulphonamide compounds
Filed: 1943-10-19
Abstract: p-Sulphonamidobenzamidines are produced by interaction of ammonia or a primary or secondary amine with the product obtained on treating benzamidine-p-sulphonic acid with chlorosulphonic acid.  In examples: (1) a solution of benzamidine-p-sulphonic acid in chlorosulphonic acid is heated to 100 DEG  C. for 30 minutes and the cooled mixture is treated at below 10 DEG  C. with aqueous ammonia to precipitate p-sulphonamidobenzamidine; (2) benzamidine-p-sulphonic acid is heated with chlorosulphonic acid and thionyl chloride under reflux at 80 DEG C. for 30 minutes to produce the corresponding acid chloride, and concentrated ammonia solution is added to the iced filtrate until the solution is alkaline to Brilliant yellow and yields crystals of p-sulphonamidobenzamidine; (3) benzamidine-p-sulphonic acid chloride, prepared as in (2), is heated at 100 DEG  C. for 3 hours with 2-aminothiazole in pyridine and the cooled solution is diluted and made neutral to phenolphthalein; the pyridine is then removed by evaporation in vacuo at room temperature to obtain 2-(41-amidinobenzenesulphonamido)-thiazole.  Benzamidine-p-sulphonic acid is preferably produced from p-sulphonamidobenzoic acid by heating with another sulphonamide, e.g. benzene sulphonamide.

Title: Aluminium hydroxide production
IPC: C01F7/447
Filed: 1964-04-27
Abstract: Aluminum hydroxide of the hydrargillite structure and practically free from metallic impurities is prepared by maintaining an alumina gel cake, obtained by filtering and washing a suspension of aluminum hydroxide containing at least 0.1 gram-ions of a monobasic acid per gram mol. of Al2O3, protected from drying at 10-60 DEG  C., until the whole mass is converted to hydrargillite.  The gel-cake may contain 10-20 wt. per cent alumina and may be obtained by continuous precipitation from a solution of a soluble aluminum compound maintained at a pH from 8 to 9.  The hydrargillite mass may be gradually dried at a temperature <110 DEG  C.  The aluminium hydroxide may be used as a film-forming agent, absorbent or filler. In the examples the gel-cake is placed in an impervious plastic-bag and allowed to stand either at 40 DEG  C. for 5 days or room temperature for 20 days to effect conversion to hydrargillite.
