Title: A method for the electric welding of metallic tubing
IPC: B23K13/04
Filed: 1959-03-05
Abstract: 908,804. Welding by fusion. HASUMI, T., and KAWASHIMA, J. March 5, 1959 [Aug. 16, 1958], No. 7733/59. Class 83 (4). In welding outwardly-projecting flanges on the opposite edges of tubing formed from metal strip, the tubing is advanced relatively to a tubular magnetic body having a longitudinal gap so that the flanges pass through the gap and a high-frequency current is provided in the same direction in each flange, the current passing through a conductor bar within the inner space of the magnetic body and spaced from the flange. In an embodiment, a copper tube 11 whose seam is formed by flanges 12 is passed in the direction of the arrow 20 beneath a conductor bar 14, high-frequency current being passed through the bar from a terminal 15 to a contact 18 slidably engaging the tube upper surface and along the tube to a contact 17 slidably engaging the lower surface of the tube. A gapped tubular magnetic body 13, e.g. of ferrite is arranged about the bar 14 with the flanges in its gap. Due to " access' effect the conducted current is caused to flow in the flanges and currents are also induced in the flanges which fuse to effect a weld without applying lateral pressure. In a modification the tube is also encircled by a split magnetic body 30, e.g. of ferrite and a rod 29 of, e.g. ferrite is arranged within the tube.

Abstract: 954,004. Sugar-cane mills. HONOLULU IRON WORKS CO. Feb. 27 ,1963, No. 7919/63. Heading B2A. A sugar-cane mill having a pressure roll 1, Fig. 1, and back-up rolls 2, 3 mounted between transversely-spaced housings 4 and a ram 20 mounted on each of said housings for forcing the pressure roll downwardly towards the rolls 2, 3, includes eccentric means interposed between each ram and the related housing for selectively adjusting the position of the ram laterally relative to the axis of the pressure roll. The pressure roll is vertically adjustable between sliding wear plates 19, each ram 20, which is mounted in a top cap 21 acting on the top wall 22 of the journal box 17, being adjustable laterally or radially so as to maintain an even pressure between the rolls in spite of differences in the resistance to compression of the sugar-cane mat fed between the rolls. The force of the ram is applied through a bracing-block 66 having a spherical interfit with the lower end of the ram. Stops 67 engage abutments in the feet 60 to limit upward movement of the roll 1. Each ram 20 is adjustable by being mounted in an eccentric cylindrical socket 23 in an eccentrically-bored cylinder 24 and rotatably mounting the cylinder in an aperture 27 extending axially through the top cap 21. The eccentric cylinder 24 is adjustably rotatable in its seat 27 by a tool engaging eye bolts 30. Each ram is held locked in its selected position by a locking flange 31, Fig. 5, having a number of spaced holes 32 to receive a bolt 33 screwable into a bolt-hole 34, the set position being indicated by scales 36. Each ram 20 and its eccentric cylinder 24 is removable as a unit without removing the cap from the housing. Pressure fluid is applied to chamber 37, Fig. 4, via a port 38, and to retain the unit in assembled relation during removal, locking plates 39 engage an annular shoulder 40 on the ram. The cylinder and top cap are interlockable by a pair of wings 41, Fig. 5, on diametrically opposite sides of the cylinder, insertable through opposed slots 43.

Abstract: 329,076. Stanton, E. J. March 14, 1929. Sale apparatus, specially adapted for attachment to the backs of seats &c. The coin is inserted through an aperture in the top of the casing into a slide, which can then be moved along to operate delivery-mechanism that is supported, with a magazine for the articles to be sold and a receptacle for the coins, by the front or cover of the casing. This cover 15, Figs. 4 and 6, can be readily removed from the casing 14, Fig. 3. Coin action, mechanical connection.-The coin is inserted through an aperture 24, in a plate 23, Fig. 10, into an aperture 25 in a slide 21 which can be moved on guideways between the plate 23 and a lower plate 22 by means of a knob 28. Operative motion of the slide is normally prevented by one or more pawls pivoted below the plate 22 and projecting therethrough so as to engage recesses in the bottom of the slide. But these pawls are held out of engagement by a coin in the aperture 25. The slide can then move forward to bring the coin into position so that it falls through a gap 26 in the plate 22 and is directed by a guide 27 into a coin receptacle 35, Fig. 4. A spring-controlled pawl projecting through a slot in the plate 22 and engaging a rack on the bottom of the slide ensures that the slide shall make a complete journey in either direction. Delivery mechanism.-The lowest package of a pile 43, Fig. 6, in a magazine 44 is delivered by the rocking of a frame, consisting of an upper horizontal member 47, lower horizontal members 48, 49, and levers 46 turning on pivots 45 on either side of the magazine. The member 48 normally serves to retain the lowest package, while the member 49 pushes the package when the frame is rocked, so that the package falls into the receptacle 58 for removal through the opening 59. The frame is normally held with its upper end away from the front or cover 15 of the casing by a pivoted stop 50. When the slide 21 moves forward a rod or cam 38 projecting downwards therefrom first releases the stop 50 and then pushes the frame over to effect delivery. Registering; indicators; empty machines lock. ing.-At each forward motion of the slide 21, a pawl 61, Fig. 11, carried by the rod 38 engages a ratchet wheel 60 which may be connected to an indicator outside the casing. With the emptying of the magazine a stop 65 on the wheel 60 comes into position to engage a stop 66 on the part 38 and thus prevents the return of the slide to the position in which a coin can be inserted. Rotation of the wheel 60 winds a spring, but backward rotation is prevented by a detent 62. A projecting piece is connected to the cover 15 so that when the cover is removed the projection will lift the detent 62 and allow the spring to reset the wheel 60 in its initial position.

A source of charged particles, i.e. electrons or positive ions, comprises a parallel walled cavity 4 having an internal electron emissive coating and within which a plasma of an ionizable substance, e.g. caesium supplied from a reservoir 10, is formed by contact ionization; the two parallel walls 1, 3 are maintained at two different temperatures whereby a voltage difference is developed between them so that with a suitably small spacing between the walls, e.g. 0À2-2 mm., an additional energization of the electrons within the plasma is achieved and an arc discharge is established across the cavity. Under these conditions the escape of unionized neutral atoms is avoided. The upper or lower wall may be maintained at the higher temperature and the walls may be of the same or different materials. The following examples are given: (1) tungsten walls at 1900‹ K and 1200‹ K producing 1À2 volts; (2) tantalum at 1900‹ K and tungsten at 1200‹ K producing 1À5 volts, and (3) rhenium at 2500‹ K and molybdenum at 1900‹ K producing 1À5 volts. In cases (2) and (3) the wall 3 at the higher temperature is formed of the material of higher work function. The caesium is brought to a temperature of 600‹ K and a pressure of the order of 4 Torr. The lower wall may be provided with a re-entrant lip (15, Fig. 3, not shown), opposite the charged particle exit orifice 2 and the caesium inlet pipe 8 may enter the cavity through the side wall (4, Fig. 4, not shown). Electron or ion streams, e.g. for ionic propulsion, may be produced according to the signs of the focusing and accelerating electrodes 5, 6.
