Title: Improvements in and relating to electric arc welding
IPC: B23K9/12
Filed: 1934-05-10
Abstract: 425,800. Uniting by fusion. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Naamlooze Vennootschap Machinerieen - en Apparaten Fabrieken; 30, Croeselaan, Utrecht, Holland) May 10, 1934, No. 14127. [Class 83 (iv)] In automatic arc welding with completely covered electrodes, using a holder carrying two or more electrodes 5, 6, 7, Fig. 1, which are brought successively into the welding position by moving part of the holder, a feed apparatus is used which permits of a rapid return motion of the holder after the consumption of an electrode. In one arrangement the armature of the feed motor 2 which is normally fed at 12 to 24 volts is fed at 220 volts in the reverse direction. In a modification a rapidly set high speed reversing gear is incorporated in the transmission gear 3. Another modification employs a magnetic coupling in the gear 3 which may be disengaged to enable the holder to be raised quickly by hand. Uncoupling may also be effected by moving the rollers 12 which are for this purpose journalled in eccentric bushes. In a further modification the weight of the bar 4 and the electrode holder forms the driving force during feeding and the motor 2 locks the bar by a ratchet device against downward motion only. The rapid upward movement may be initiated automatically by means of a lever 14, Fig. 2, on the holder co-operating with a stop 15 on a bar 16 coupled to a reversing switch 17. The upward motion is stopped by providing a second stop 31 on the bar 16. The switch 17 may also control the traverse motor so that traversing is interrupted or reversed in direction during the return motion of the holder. Before reaching the top of its travel the rollers 20 on the locking pin 19 of the electrode holder engage the lever 22 and the pin is withdrawn so that the disc 25 will rotate due to the weight of the laterally arranged second electrode and the latter will move automatically into the welding position. In a modification idle return motion is eliminated. Every alternate electrode clamp is constructed so that it can be moved into and out of the electrode holder. As an electrode burns away the clamp is moved out of the holder by a small motor at twice the fusing speed and the holder is retracted at the fusing speed. When the electrode is consumed the next electrode is brought into position by simply rotating the holder.

IPC: B31C1/00
Filed: 1916-10-06
Abstract: 110,028. Carter, W. Oct. 6, 1916. Paper tubes.-In a machine for making paper tubes, particularly short tubes for collars and washers, by winding strip material on a mandrel, means are provided to move the pasting-device out of contact with the strip, and to arrest the machine, when the tube reaches a predetermined thickness. The strip is drawn from a roll mounted on a spindle 3 between a star-wheel 5 and depending finger 6, and passes round guiderollers 12, 16, 21, to a slotted mandrel 11. Tension is applied to the strip by one end of a weighted lever 13 bearing against the strip on the roller 12. Adhesive is applied to one side of the strip by a roller 18 running in a bath 17 provided with an adjustable weighted scraper 22 for removing surplus adhesive. The bath and roller are movable about a pivot 17<a> and are raised to the operative position by a spring blade 27 on a hand-operated lever 30, retained by a detent 31. When the tube on the mandrel reaches the required thickness, the detent is tripped by a lever 34, the upper end of which has a shoe resting against the tube and the lower end an adjustable screw 36 engaging the detent. The mandrel spindle has fast and loose pulleys, and is driven by a belt, not shown. The belt is shifted by a fork carried on a sliding rod 44 moved by hand to put the belt on the fast pulley and retained by a spring catch 45 engaging a notch in the rod. The catch is released when the tube reaches the required thickness by the lever 34 engaging an adjustable screw on the catch. The rod is then moved by a spring to throw the belt on to the loose pulley. The tube is doffed by a sleeve surrounding the mandrel, normally retracted by a spring and moved along the mandrel to remove the tube by a pedal and bell-crank lever.

Title: Means for regulating the current in rectifying apparatus of the mercury vapour or arc type
IPC: H02M1/04
Filed: 1933-05-17
Abstract: 421,404. Converting. FORGES & ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT, 75, Boulevard Haussmann, Paris. May 17, 1933, No. 14287. Convention date, May 25, 1932. [Class 38 (ii)] In grid-regulated mercury-arc rectifiers, the A.C. voltage applied to the grids is of harmonic frequency with respect to the anode voltage and is composed of two or more harmonics which may be separately or jointly varied in phase or magnitude to effect regulation. A voltage of the same frequency as the anode voltage, or a D.C. voltage may be superposed on the harmonic voltage. The harmonic voltage may be derived by full-wave rectification of current of the same frequency as the anode voltage, the resultant current of the form shown in Fig. 2 being fed through a resistance R1, Fig. 3, in circuit with a resistance R2 and D.C. source E1, thus producing a voltage wave of the form shown in Fig. 4 across the resistance R2. The positive peaks of the latter (which occur at twice the frequency of the anode voltage) may be used to control starting of current in pairs of anodes of opposite phase either by application to a pair of connected grids or to a single grid associated with the two anodes. Specifications 209,426, [Class 38 (ii)], and 395,632 are referred to.

Abstract: 1,173,790. Resistor. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 25 March, 1968 [29 March, 1967], No. 14312/67. Heading H1S. An insulating substrate carries a film having a desired pattern formed by condensing ruthenium tetroxide from the gaseous state and decomposing it into ruthenium dioxide by irradiation with ultra-violet radiation, and unwanted tetroxide being removed by evaporation. The gaseous tetroxide is diluted with an inert gas, and the substrate is kept below 0‹ C., preferably about - 80‹ C. for optimum deposition. The deposit is irradiated with light from a mercury vapour lamp, the pattern being formed by either masking unwanted areas with a non- reactive shield, directing light on to the required areas by an appropriate optical system, or focusing the light to a point and moving the substrate relative to it, so mapping out the pattern. The dioxide formed has a thickness of 25-1000 Š, the remaining tetroxide being evaporated at 20-55‹ C., optionally in a current of dry air. The substrate is of a non-reactive inorganic material, e.g. glass, and other circuit elements, such as transistors or capacitors, may be carried on it.
