Title: Improvements in or relating to drum winding machines for yarn or the like
IPC: B65H54/38
Filed: 1932-04-07
Abstract: 399,546. Drum winding-machines. UNIVERSAL WINDING CO., 95, South Street, Boston, U.S.A. April 7, 1932, No. 10019. Convention date, Sept. 28, 1931. [Class 120 (ii).] In a drum winding-machine for winding yarn, thread, cord, &c. into cops, cones, &c. the formation of ribbons &c, is prevented by periodically changing the relative angle between the package and the drum so as positively to separate them at the end at which the peripheral speed is greatest thereby varying the driving contact and disrupting synchronism between rotation of the package and the traverse. The winding- units are on cross frames 4 supporting bearings 6 of the shaft 5, Figs. 1 and 4, of the driving drum 7 which is as described in Specification 339,679, [Class 120 (ii), Spinning, twisting, &c.], and may be driven by an electric motor at the end of the frame. The cone C on a tube X is carried by a holder 11 held in the winding position by a detent spring 22 and a hinge 20, the cop support and the means for axial tilting during winding being as described in Specification 275,543, [Class 120 (ii), Spinning, twisting, &c.]. The cam 50, Figs. 1 and 5, by which the cop axis is tilted is however periodically movable to avoid ribbon winding, the cam 50 being pivoted on the same axis 26 as that of the rod 18 supporting the holder 11, and being slowly oscillated by a crank or an eccentric 57 acting on a forked arm 55 secured to the support for the cam 50. The eccentric 57 may be rotated from any constantly moving part of the machine, e.g. from the shaft carrying the bunter-cams.

Filed: 1926-04-16
Abstract: 250,965. British Thomson-Houston Co., Ltd., (Assignees of Baker, W. R. G.). April 18, 1925, [Convention date]. Phase, changing.-In a system for converting high frequency single phase current into polyphase current, the single phase current is supplied to a number of circuits of different impedance values whereby currents of the required phase relationship are produced in the primary windings of a transformer, the secondary windings of which are connected to a polyphase distribution system to enable high frequency signalling current to be supplied to each phase of the system. According to one arrangement, Fig. 1, an oscillation generator comprising a thermionic valve 1, the plate circuit of which is supplied from lines 5, 6 through a choke 7, energizes through a blocking condenser 8 an oscillatory circuit comprising an inductance 9 and condenser 12. This circuit also includes a condenser 15 and inductance 13 whereby the desired phase relationship is obtained between currents supplied through amplifying valves 23 to the primary windings 17, 18 of a Scott transformer, the secondary windings 19 of which are connected to a three phase distribution system 20 through condensers 21 and chokes 22. According to an alternative arrangement, Fig. 2, high frequency single phase current is supplied to the primary winding 26 of a transformer the secondary winding 25 of which supplies three circuits which include respectively inductance 27, resistance 28, and capacity 29. These circuits also include variable resistances 30, 31, 32 whereby their impedance values may be so ad. justed as to obtain the desired phase relationship between the currents which energize the grids of valves 33, the plate circuits of which include the primary windings of transformers 34, 35, 36 for supplying high frequency three phase current to the distribution system. Specification 226,227 is referred to.

Title: Methods of improving the mechanical properties of metals and their alloys
Inventor: BOURNE ALAN ARTHUR
IPC: C22F1/14
Filed: 1964-03-11
Abstract: 1,134,492. Improving physical properties. JOHNSON, MATTHEY & CO; Ltd. 3 June, 1965 [11 March, 1964; 20 March, 1964; 17 April, 1964], Nos. 10239/64, 11886/64 and 15973/64. Heading B3V. [Also in Divisions B1 and C7] A metal or alloy which has been strengthened by the incorporation of a dispersed non-metallic phase such as an oxide, carbide, boride, silicide or nitride has its mechanical properties further improved by cold-working and subsequent annealing, the amount of cold-working being such that the recrystallization results in a structure of elongated grains which are orientated in the direction of working. The degree of orientation may be such that at least 50% of the grains have their major axes lying within 30 degrees of the direction of working, while the grains may have a length width ratio greater than 5 and up to 12.5. Preferably the amount of cold-working exceeds 80%. The invention is applicable to both noble and base metals and their alloys, which may have been made by powder-metallurgical methods, but is concerned particularly with the treatment of dispersionstrengthened platinum and its alloys, which may subsequently be used for catalyst gauges, electric furnace windings, resistance thermometers, thermocouples, or bushings, melting crucibles or stimers used in the manufacture of glass. Particular materials exemplified are sintered platinum/0.04% titanium carbide, platinum/0À5% thorium, and 10% platinum/ 90% thorium/0-04% titanium carbide, which were cold worked by about 95% and subsequently annealed at 1400‹ C. Base metal compositions are exemplified by copper containing 0.04% of titanium carbide, which was coldreduced by about 80% and then annealed at 350‹ C. The precious metal base compositions are sintered at 1400‹ C. for 1-3 hours, possibly after the powders have been sinterered at 800‹ C. prior to pressing at 8-10 tons/sq. inch. Some specimens were re-pressed to 80% of theoretical density and re-sintered for 2 hours at 1400‹C. Compositions containing thorium nitrate were produced by mixing platinum powder with an aqueous solution of thorium nitrate, dried at 100‹ C., and heated for 3 hours at 800‹ C. in hydrogen, while to prepare the copper-base composition copper powder was reduced in hydrogen at 350-400‹ C. for 4 hours, mixed with titanium carbide, dry-milled in a polypropylene mill, annealed at 450‹ C. in vacuum for 2 hours, pressed at 10 tons/sq. inch and sintered in vacuum for 4 hours at 900-950‹ C.

Abstract: <PICT:1064443/C6-C7/1> Selected areas of a cathode to be electroplated are stopped off by placing adjacent each such area a thief cathode which is at a more negative potential than the main cathode.  The thief cathode may conform geometrically to the area being stopped off and to avoid metal deposition it may be coated with a metal such as platinum as disclosed in Specification 1,063,781 Reference is made to the plating metal being Cu, Sn, Zn, Ni, or Cr.

Title: Device for controlling the operation of moving picture cameras

Filed: 1945-04-28
Abstract: 598,967. Kimematograph cameras. BROIDO, J. J. April 28, 1945, No. 10769. Convention date, Oct. 23, 1943. [Classes 97 (i) arid 98 (i)] The camera mechanism is controlled to produce single instantaneous, single " time " or kinematographic exposures by the engagement, with a projection on a control disc carried by an operating shaft of the camera mechanism, of pawls selected by rotating a control knob and operated by depressing it. As shown, the shutter blade 11 rotates in front of the aperture 19 on a shaft 10 controlled by an abutment 9 normally held by a pawl 5 releasable by the button 2. The latter is also rotatable but its elongated foot 3 bears on the pawl 5 in all positions. If this is released alone normal kinematographic exposure is effected. In one position of the knob 2 the foot 3 actuates also the pawl 12 against which the abutment 9 strikes after nearly one revolution. When the button is released the parts return to the position shown. A single exposure is thus made. In another position of the knob 2 the pawl 13 is actuated to stop the abutment 9 after half a turn when the shutter is open. Release of the button completes the exposure. In a further position of the knob 2 the foot 3 is engaged above a projection 17 to prevent accidental exposure or under it to secure continuous kinematographic exposure.
