Abstract: 279,833. Berthold Messinglinienfabrik und Schriftgiesserei Akt.- Ges., H., (Assignees of Laarmann, 0.). Oct. 28, 1926, [Convention date]. Set-off, preventing. - In multi-colour and other printing, in which sheets to be printed are passed several times through the machine, and are interleaved with set-off sheets, the set-off sheets, which are taken from ai pile composed of alternate printing and setoff sheets, are fed by hand to a pivoted device which deposits them upon the delivery table between the printed sheets. The pile 51, Fig. 2, of printing and set-off sheets rests on a table 50, from which the printing- sheets are fed by hand to the printing-machine. The set-off sheet remaining on the top of the pile is pushed by hand between rollers 55, by which it is led into a box-like container 54 composed of strips 57, carried by lever-arms 56, and connected together by rods 59. The bottom of the container is closed by a pivoted strip 61. The arms 56 are pivoted on a pin 62, and can be pulled down by a tension member 63, which passes around a segment 65 loosely mounted on the shaft 64 of the delivery fly-frame 70. The segment carries a driving-pin 66, which can be engaged by a sliding bolt 68, Fig. 3, carried by an arm 67, which is secured on the shaft 64 of the delivery-frame. As the frame 70 returns, after having laid the printed sheet upon the delivery-board 52, the bolt 68 engages the pin 66, and the container 54 is drawn down over the delivery-board 52. The closing-strip 61 is opened by a stop 72, to permit the set-off sheet to leave the container. The bolt 68 is then withdrawn by a fixed wedge 73, whereupon the container is raised by a spring 74, and the set-off sheet is laid upon the board 52.

Filed: 1951-11-28
Abstract: 745,629. Welding by fusion. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 27, 1952 [Nov. 28, 1951], No. 27964/51. Class 83 (4). [Also in Group XI] Parts of thermocouples, electronic devices or crucibles of refractory metal are held by manipulators 27 slidably mounted in ball and socket joints 28 on the wall of a chamber 10 so as to be readily presented to a H.F. corona discharge from an adjustable tubular electrode 34 within the chamber and arc welded thereby. The tungsten electrode part 34 is carried by a tubular electrode part 35 supported on a universal mounting 36 at the end of a tube 20 maintained at a high radio-frequency potential by a sliding contact 24; and a controlled atmosphere, preferably molecular, e.g. hydrogen, is passed through the tube 20 and through a flexible rubber tube 38 to the hollow electrode parts 34, 35. The controlled atmosphere is also admitted to the chamber 10 by a tube 13, and when this is a molecular gas, e.g. hydrogen or nitrogen, heating is effected partly by molecular dissociation and recombination and partly by impact of charged particles on the work. Hydrogen has a de-oxidizing and cleaning action, and argon may be added to give a reduced heating effect. The electrode 34 is maintained at a high R.F. potential at the high potential end of two concentric conductors of a resonant line, the outer conductor 19 being connected at one end to the wall of the chamber 10 and at its outer end to the end of the inner conductor 20. The R.F. energy is supplied to the tube 20 through a terminal 24 sliding in an insulated slot in the outer tube 19. The frequency is selected so that the resonant line is an odd number of quarter wavelengths long. The chamber 10 is cylindrical with water cooling pipes 11 in the cylindrical wall and has circular flat back and front walls with transparent mica windows. The back wall and window are thinner in case of explosions. Excess gas is removed through a pipe 15 and is burnt. According to the Provisional Specification, apparatus for brazing and welding refractory metals comprises an electrode formed as a thin tungsten rod fixed on the end of the inner concentric tube 20, and the outer tube 19 extends into the chamber 10 and tapers to hold a small tungsten tube through which the rod electrode projects axially. A molecular gas, e.g. hydrogen, is passed into the outer concentric tube 19 and through the small tungsten tube, at the tip of which it is dissociated by the H.F. field and recombines to form a flame within the chamber 10.

[Also in Group II] A method for removing splinters adhering to the metal of conductors for electric cables comprises mechanically lifting and simultaneously electrically burning the splinters. Metal ribbon 4 is subjected to brushing by a brush 3 comprising a cylinder 1 carrying longitudinal bands 2 of metal bristles. The bristles are bent as shown at 11 in Fig. 5, which facilitates the lifting of splinters 13 as the brush rotates. The axis of the brush is arranged at 45 degrees to the direction of movement of the ribbon. To effect the burning of the splinters the bristles of the brush are elec trically connected together and to a ring 6 mounted upon and insulated from the brush shaft. The ring 6 is connected to the positive terminal of a source of direct current through a resistance 8 and an inductance coil 9 arranged in series. The negative terminal is connected to the ribbon 4 at 5. Alternatively, an alternat. ing current and a rectifier may be used. In operation, as the brush 3 rotates the splinters are lifted by the brushes and burned by the arcs flashing between the ribbon and the band of bristles. as they leave the ribbon. Further brushing for cleaning and polishing is performed by circular metal brushes 10 and 16 rotated by a motor 17. Finally, dust is removed by a nylon brush 18. For operating on wire conductors, the " electrical " brush consists of a cylinder 21, Fig. 8, carrying an odd number of radial bristles 22 connected to a ring 23. The operation is similar to that for metal ribbon except that the brush is rotated about its axis and simultaneously about the wire, which passes through the centre of the brush. The cleaning, polishing and dusting brushes also have two rotational movements.
