Title: Improvements in the control of electric arcs used in welding or metal spraying processes
IPC: B23K9/067
Filed: 1949-07-13
Abstract: 685,296. Arc welding electrode holders. BALLARD, W. E. July 13, 1950 [July 13, 1949; Aug. 24, 1949; Dec. 7, 1949], Nos, 18455/49, 22001/49 and 31411/49. Class 39(iii) [Also in Groups XXII and XXIX] Electric arcs used in welding or metal spraying are stabilized by ionizing the gas in the path of the arc by passing the gas through the field of emissions from a radioactive material before it enters the path of the arc, the radio-active material 14 being separate from the electrodes and spaced from the arc. Air or preferably an inert gas, e.g. argon, helium or nitrogen flows first over a disc 14 of radio-active material through an aperture in which passes a tungsten electrode 13 from which the arc passes to the work. A filler rod may be melted in the arc. In welding or spraying metals. two wires forming electrodes are mechanically driven through tubular guides in the sides of a metal casing 11, and a propellant gas from an inlet 10 passes over the radio-active material 14 at one end of the casing to a nozzle 12 around the arcing electrodes from which the metal is sprayed. A wire to be melted may be fed to the arc. A natural radioactive material, e.g. radium, thorium or polonium is used, or a radio-active isotope made in an atomic pile or cyclotron, e.g. radio-active phosphorus 32 or radio-colbalt, either elemental or combined. The polonium is mounted on a base permeable to alpha rays. A low-voltage high-amperage current is used in the arc, e.g. 30 volts and 120 amps A.C. between advancing electrodes. Alpha or beta ray emissions are used, and the distance between the material 14 and the arc, e.g. 3-8 cms., is adjusted according to the material. in a gas welding torch the flow of inert gas over a tungsten electrode is about 7 litres a minute. According to the Provisional Specification, the radio-active material is incorporated in one or both electrodes, or is arranged between or surrounding the electrodes near the arc. The tips of the guides of wire electrodes may be formed of radio-calcium. Gamma radiations may be used. Stabilization of the arc may be further aided by a high-frequency current superimposed on the arc. The metal spraying pistol used may be constructed as in Specification 616,084, [Group XXIX], which is referred to.
Patent GB-909294-A (GB)
Title: Spinning or twisting spindle with a dead spindle shank
IPC: D01H7/06
Filed: 1961-05-23
Abstract: 909,294. Spinning &c. spindles. KEYSER, J. J. May 23, 1961 [May 25, 1960], No. 18493/61. Class 120 (2). In a spinning &c. spindle structure of the kind comprising a dead blade 18 and a coaxial stationary sleeve 6, respectively rotatably carrying members 21, 11, for supporting the upper and lower ends of a rotatable bobbin sleeve 2, the lower member 11 being driven, the position of the blade 18 with respect to the sleeve 6 can be varied to permit sleeves of different lengths to be used. In Fig. 1, the lower part of the sleeve is threaded and is secured to the spindle-rail 1 by a nut 14 ; it also carries a socket 15 accommodating the lower end of the blade. The lower end of sleeve 6 has an elastic ring 19 which can engage one of a number of grooves 20 in the end of the blade depending on the height of spindle required, additional rings 17 being provided in grooves in the inner wall of the socket. The upper member 21, Fig. 1a, is connected to the blade by a pin 22 with a head 23; the pin extends through a bushing 25 of the section shown, and the head rests on a plate 26 with a spherical seating, whereby the sleeve can adjust itself should the parts vibrate, and the member 21 is prevented from being withdrawn when the bobbin sleeve is doffed. The lower -member 11 is connected to parts the upper of two collars 8, 9 of a wharve 7 mounted to rotate on sleeve 6 ; it is convex in shape and carries a coupling 27 to transmit rotation to the sleeve 2 without preventing its withdrawal. A brake consisting of co-operating nuts 4, 5 and a handle 3 is provided. In Fig. 6, the blade is hollow and is connected to a rail 53 the position of which can be adjusted as desired; the blade has rotatably connected to it at 58 a sleeve carrier 57 on which the sleeve 2 is a driving fit while the upper wheel collar 12 is positioned outside the bobbin sleeve and carries an elastic ring 28 which is free of the carrier 57 but grips tightly when the sleeve 2 is interposed. The sleeve 6 is spaced from the blade, so that the rail 53 can be lowered carrying the blade and carrier 57 to a position at or below the collar 12 leaving the sleeve 2 with or without a wound package supported for easy removal on the ring 28. The rail 53 may be adapted as a scale-beam to ascertain the weight of a package ; to this end it is raised before and after winding until the parts 57 and 2 are supported just above the ring 28. In another form, Fig. 3 (not shown), the lower end of the blade is threaded, and is raised and lowered by rotating a worm and worm-wheel and in a further form, Fig. 4 (not shown), the sleeve 2 is mounted as in Fig. 1 and the blade as in Fig. 6 ; for donning and doffing the sleeve the rail 53 is lowered until the member 21 comes to rest on the member 11.

Title: Apparatus for measuring the thickness of dielectric members
IPC: G01B7/06
Filed: 1968-04-19
Abstract: 1,215,540. Measuring thickness. OWENSILLINOIS Inc. April 19, 1968, No. 18605/68. Heading G1N. A sensing head for measuring the thickness of glass comprises a cylindrical electrode 46 energized from a high frequency generator (60) and a rod-shaped pick-up electrode (49) disposed centrally of the cylindrical electrode. The electrodes are mounted as shown with plastics insulation 47, 48 within an aluminium block 35 supported on rails 39 and urged towards the glass by a spring 55. A wheel 43 contacts the glass to ensure an accurate spacing between the electrodes and the glass. The sensing head may be used to measure the wall thickness of glass bottles or the thickness of glass sheets. For testing a succession of glass bottles, brought one at a time to a testing station, a plurality of sensing heads may be spaced vertically with their electrode axes horizontal so that as a bottle is rotated about a vertical axis its entire circumference is scanned by the electrodes, which in practice would be positioned where experience shows thin wall sections are most likely to appear. To overcome inertia, the bottles may be given some initial rotational movement by frictional contact with a rail (21), Fig. 1 (not shown), prior to arriving at the testing station. The voltage picked up by the pickup electrode is compared with a reference voltage obtained from the generator (60) and if the bottle is too thin a rejection mechanism is operated.

The sail is strengthened by cords 13, 14 and by rigid supports 15 inserted in loops in the sail. Auxiliary buoyant bodies may be provided to dip in the water should the sail tilt laterally. The sides 2, 3 are in the same plane as the sail at its forward end but are supported on inclined rods 4 at its rear end. The sliding member on which the aircraft is supported may be a cradle, a band conveyer, or a flat boat-like body with a stretched sailcloth surface.

Filed: 1925-07-27
Abstract: 237,907. Cantono, E. July 29, 1924, [Convention date]. Buffers. - The ordinary suspension springs of a vehicle are supplemented by devices comprising two angle-irons A, C pivoted respectively t'o the frame and axle at B, D, pivotally connected together at 0 and having their free arms connected by a spring E tending to resist the movement of the frame towards the axle. The arrangement is such that the upward thrust exerted by the supplementary devices on the frame increases as the axle and frame move away from each other so that the decreasing upward thrust of the ordinary suspension springs is compensated. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use, in place of the spring E, of a spring device acting in the same manner but with the spring arranged for compression; also, the modification shown in Fig. 3 (Cancelled) in which a link C, pivoted to the frame at B, is pivoted at O to an angle lever A pivoted at D to the axle, a spring device E being interposed between the free arm of the lever A and the pivot B. This subject-matter does not appear in the Specification as accepted.
