Title: Improvements relating to a method and apparatus for the manufacture of wire rings
Inventor: MEACHER JOHN WYATT
IPC: B23K11/00
Filed: 1969-04-18
Abstract: 1,254,361. Making wire rings; curving by rolls; welding by pressure. WESTMINSTER ENG. CO. Ltd. 10 April, 1970 [18 April, 1969], No. 19839/69. Headings B3A, B3E and B3R. A method of making a wire ring includes the steps of feeding a continuous length of wire 95 past a first welding electrode 48, forming the length to take up a ring shape with the free end of the wire having its axis displaced from the axis of the section of the wire passing the first electrode 48, clamping the free end of the wire to a second welding electrode 6 located adjacent the first electrode 48, clamping the wire to the first electrode 48, cutting the wire adjacent to the electrodes 6, 48, causing relative movement of the electrodes to bring the free end and the cut end of the wire together with their axes substantially aligned, and butt welding the free end and the cut end together. As described the wire 95 is formed into a ring shape by rolls 82, 83, 84. Roll 82 is fixed and rolls 83, 84 can be adjusted vertically by screws 80, 81 and horizontally by screws 93. The rolls 82, 83, 84 are adjusted so that the free end of the wire is displaced below the level of the first electrode 48. The wire is fed until the free end of wire contacts a movable cutter blade 73 which has been raised to an intermediate position opposite the second electrode 6. The free end of the wire is then clamped against electrode 6, which is fixed, by clamp 12 and the wire is clamped against electrode 48, which is movable, by clamp 55. The movable cutter blade 73 is then raised and co-operates with a fixed blade (not shown) to cut the wire, the electrode 48 moving upwardly with the wire 75. The electrode 48 is then lowered until the ends of the wire are aligned and is then moved towards electrode 6 until the ends of the wire contact each other. The ends of the wire are then butt welded together. The movable electrode 48 is carried by a frame (not shown) which is carried by a shaft (not shown) which is supported for rotation in a housing 45 on a slide 36. The frame can be tilted to raise or lower the electrode 48 by a ram 66, the frame and ram 66 being insulated from the slide 36. The slide 36 can be moved horizontally to move the electrode 48 towards the electrode 6 by a ram 39. The welding device may be in the form of an attachment for a conventional ring forming machine or may form part of an integrated ring forming and welding machine.

Title: The manufacture of dichloro-2-methyl-anthraquinones
Filed: 1930-06-30
Abstract: A mixture of isomeric dichloro-2-methylanthraquinones (comprising mainly the 1 : 5- and 1 : 8-dichloro-compounds) is manufactured by introducing gaseous chlorine into a solution containing sulphuric acid and 2-methylanthraquinone at a temperature between room temperature and 150 DEG  C., advantageously at 70-100 DEG  C., until two atomic proportions of chlorine have been absorbed, or by treating 1-chloro-2-methylanthraquinone in sulphuric acid solution with gaseous chlorine until one atomic proportion of chlorine has been absorbed.  Chlorine carriers, such as iodine or antimony pentachloride, may be added.  The resulting mixture may be separated into its components by treatment with suitable solvents or by fractionally precipitating the sulphuric acid solution.  In examples: (1) 2-methylanthraquinone is treated with gaseous chlorine at about 100 DEG  C. in solution in a mixture of sulphuric acid monohydrate and fuming sulphuric acid, in the presence of a trace of iodine; (2) 1-chloro-2-methylanthraquinone, obtained by treating 2-methylanthraquinone with sulphuryl chloride is treated with gaseous chlorine at 70 DEG  C. in fuming sulphuric acid solution in the presence of iodine; (3) 2-methylanthraquinone is treated with gaseous chlorine at 100 DEG  C. in solution in 85 per cent sulphuric acid. Specifications 16632/05, [Class 2, Acids and salts, Organic &c.], 15937/13, and 207,840, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Improvements in brush-holders for dynamo-electric machines
IPC: H01R39/38
Filed: 1928-07-09
Abstract: 313,342. General Electric Co., Ltd., and Cranston, W. M. July 9, 1928. Brush-holders. - A totally enclosed brush-holder is provided with an aperture in one side for passage of the brushes and adapted to be closed by a removable cover, and the main part of the housing member is arranged on the side of the brushway remote from the aperture whereby the brush is readily accessible through the aperture while the space above the brushway for accommodating the pressure, member and allowing the withdrawal or insertion of the brush is minimized; in addition the holder may be split so that the brushway may be adjusted for wear and a hold-off device may be provided for the brush-pressing member, this device being automatically released so that pressure is applied to the brush when the cover of the aperture is closed. Fig. 1 shows in front view a holder with the cover removed and the brush in full lines raised for removal through the front aperture and in dotted lines in its normal position. Figs. 2 and 3 show the holder in sectional side view and plan. The enclosed housing comprises a curved member 2 secured by screws 15, 16 to a front plate 3 having a brush-removal aperture 21 at its upper part, the brushway being formed by flanges 10, 11 and thickened parts 12 on the housing 2 and the lower part 18 of the plate 3. When the pressure arm 38 is raided, as shown in dotted lines in Fig. 2, the brush may be lifted from the brushway and withdrawn freely through the opening 21. Wear of the brushway may be taken up by removing the plate 3 and machining its inner surface. The aperture 21 is closed by a cover 26, Fig. 2, hinged at 27 to the housing and having flats on its hinge piece such that it will be retained either in the closed or open positions, shown in Fig. 2 in full and dotted lines respectively, by a plate spring 30 secured on its outer surface. The pressure arm 38, which turns on a shaft 37 under the action of springs 35, is coupled to the casing by a conductor 48, and is adapted to be held in its raised position by a pin 41 which runs in a bearing 14, Fig. 1, in the housing under the action of a spring 44 and engages under an extension 39 of the pressure arm. A lever 43, attached to the spring 44, enables the pin 41 to be moved by hand, but to ensure automatically that the pin shall be withdrawn and pressure applied to the brush when the cover 26 is closed, a cam 33 is provided on the cover to move the lever 43 and withdraw the pin from the extension 39 when the cover is closed. The brushholder is secured on the machine by a bracket 4 on the housing and the current connection is made through a lug 6 and clamping-screws 8 for the conductor. The degree of brush pressure may be controlled by a ratchet and pawl or like device acting on the shaft 37 and contained in a housing in the member 2.

Title: Improvements in machine guns
IPC: F41A19/03
Filed: 1929-07-04
Abstract: 338,112. Careaga, P. July 4, 1929. Machine guns. - Excessive firing speed of an automatic gun is prevented by the inertia of a train of toothed wheels mounted in the butt, the wheels being set in motion at the commencement of each firing stroke by the recuperating spring. The recuperating spring 18 is mounted within a, sleeve 101 in the butt 6 and acts on the rear face of the piston or slide bolt 4 through the medium of a hollow member 103. Pivotally mounted on a pin 105 within the member 103 is a catch 104, the lower end of which slides within a channel 102 formed in the sleeve 101 and is adapted to engage with a toothed wheel 108 at the commencement of each forward stroke. The wheel 108 is one of a train of wheels 108, 110 - - 114 arranged in a casing 117 and geared together as shown. The wheel 114 is ratchet-toothed and the teeth thereof are engaged by the arm 115 of a bell-crank lever 115, 116, the arm 116 of which contacts with a spring 119. At the end of each rearward stroke of the piston 4, a spring-pressed plug 118 mounted in the member 103 engages with the arm 116 and, against the pressure of the spring 119, lifts the arm 115 from engagement with the wheel 114. At the same time, the catch 104 trips over a tooth of the wheel 108, which is prevented from rotating in one direction by a pawl 109. At the commencement of the forward stroke, the catch 104 engages with a tooth of the wheel 108 and turns it, the rotary motion being multiplied and transmitted to the other wheels. The time taken in overcoming the inertia of the wheels considerably reduces the rate of firing. The wheels are brought to rest before the next stroke by the arm 115 of the bell crank.

Title: Improvements in or relating to electric calbe joints
Inventor: ROSEN ABEL
IPC: H02G15/10
Filed: 1957-06-26
Abstract: 891,782. Cable joints. BRITISH INSULATED CALLENDERS CABLES Ltd. June 25, 1958 [June 26, 1957], No. 20170/57. Class 38 (1). A joint between plastic sheathed telecommunication cables 1 (Fig. 1) comprises a metal sleeve 5 sealed by wiped metal or cast plumb joints 7 to brass, lead or similar tubes 6, themselves sealed to the cable sheaths 2 by moulded blocks 10 of hot or cold setting expoxy based resin compound and sleeves 14 of neoprene, vulcanized rubber or other elastomeric material in stretched condition. Flowing of the liquid resin compound further inside the tubes 6 is prevented by sealing rings 11 of neoprene. Thermally insulating tubes 12 of compressed paper protect the sheaths 2 against damage by the hot plumbing metal. The tubes 6 may fit snugly on the cable sheaths and the sleeves 14 may be replaced by thin layers of permanently plastic sealing compound. The synthetic resin material 10 may be wholly within the tubes 6 which may act as the moulds. The neoprene sleeves 14 may be within the tubes 6, the adjacent inner surfaces of which may be in contact with paper tubes which then prevent adhesion of the resin compound. Alternatively, parts of the insides of the tubes or parts of the surfaces of the neoprene sleeves which they surround may be treated with a release agent to prevent adhesion of the resin compound. The resin compound may enclose the cut back ends of the cable sheaths and parts of the individual conductors to form a water barrier. Short lengths of the insulation of the individual conductors may be removed to increase the adhesion between the resin compound and these conductors. In the case of cables having inner and outer plastic sheaths 20, 21 (Fig. 9) separated by a metal screen or armouring 22, the outer sheath 21 and screen 22 are cut back and the end of screen 22 is bound with wire 23, which is soldered to it, one end of the wire passing through an elastomeric ring 25 between inner sheath 20 and tube 6 for connection to a wire similarly joined to the screen on the other cable. Sleeves 14 of elastomeric material are provided on sheaths 20 and 21 and the solidified block 10 makes a water-tight seal between these sheaths, tube 6, the screen or armouring 22 and binding wire 23. According to the Provisional Specification, the sleeve 5 may be split, the parts being soldered together when in place.
