Title: Improvements in and relating to semi-automatic arc welding
IPC: B23K9/14
Filed: 1946-03-14
Abstract: 623,383. Uniting by fusion. WELDING SUPPLIES, Ltd. March 14, 1946, No. 7987. Convention date, March 16, 1945. [Class 83 (iv)] In a process of arc welding a number of electrodes are supported along a seam in inclined position one behind the other at a distance from each other substantially equal to the length of seam which the electrode is able to weld, an arc is started between the first electrode and the work and the electrode fed automatically into the seam so that when it is consumed it reaches the second electrode to which it passes on the arc, the second electrode is then fed into the seam and the arc subsequently passed on to the third electrode and so on. The electrodes may be flux coated with the coating at the free end resting on the seam so as to set the arc length, the welding point being automatically moved along the seam by gravity by the gradual shortening of the electrode as it is melted down. In buttwelding a seam an electrode 8 is secured in a holder 7, preferably adjustable on an arm 5, pivoted at 6 at the required angle to the pivot which is carried by a stand 3 resting on or near the plates 1 and having bolts 4 engaging the seam 2. The arm is bent so that a second stand 12 with similar arm and electrode 13 may be placed with the end of the electrode just at the point 11 corresponding to the point of removal of the electrode 8. Welding is taken over by this electrode 13 at the moment the electrode 8 is consumed and the first apparatus may then be removed and a new electrode fixed therein and placed in the stand 3 in front of the apparatus 12 so that a fresh electrode may be used when the electrode 13 is consumed. In a similar apparatus for fillet welding plates 1, Fig. 3, the pivot 6 of the arm is carried by a support 14, turnable along a sector 15 so that the plane containing the electrode 8 and scan 2 in this oblique position is perpendicular to the pivot. The sector 15 may be rotatable about a vertical shaft 16 and kept in position by springs 17. The electrode S, Fig. 1, is arranged at such an angle to the axis of rotation O that the connecting line between the contact point B or B<SP>11</SP> of the electrode with the seam and the point or the axis of rotation in a plane containing the electrode and seam, e.g. O,B or O,B<SP>11</SP>, substantially coincides with the bisectrix of the angle between the electrode and the seam, the axis being substantially perpendicular to said plane. Weld beads of uniform cross-section throughout the seam are thus obtained.

Abstract: 750,312. Automatic regulation. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 28, 1954 [March 27, 1953], No. 8478/53. Class 38 (4). [Also in Group XL (c)] A shunt voltage stabilizer consists of a cold cathode triode arranged as a relaxation oscillator, the frequency of which, and hence the current drawn, depends upon the supply voltage. The load L is supplied via series resistor R1 and is shunted by the cold cathode triode V1 in series with an anode load resistor R2 and a current limiting cathode resistor R4. The valve is shunted by a capacitor to form an oscillator, the capacitor consisting of two condensers C1, C2 in series (and if necessary C4 in parallel) the mid-point of the condensers being connected to the trigger electrode. The time constants are so arranged (as disclosed in the Specification) that increased anode voltage causes increased frequency of oscillation, and the increased voltage drop across R1 tends to maintain the applied voltage constant. Additional smoothing may be obtained by R5, C5. In a modification, Fig. 2 (not shown), the voltage across C2 is applied to the trigger electrode via a voltage doubling rectifier so as to increase the sensitivity of the circuit. Specification 732,776 is referred to.

[Also in Groups XXVIII and XXXVI] A method of forming a joint between the ends of or repairing elongated thermoplastic articles, e.g. rods, tubes or the insulation of electrical conductors comprises enclosing the ends of the article in a mould having an injection aperture and one or more spew outlets, injecting into and maintaining through the mould a flow of molten thermoplastic material to heat the ends of the article to fusion temperature, and then cooling to bond the injected material to the ends of the article. The injected material may be of a different colour to that of the article so that on fusion of the article the material issuing from the spew apertures contains traces of this colour whereupon injection may cease. The mould may be transparent to provide visual indication of the joint. Three embodiments are described. Firstly electrical cable ends 1, 2 with insulation 4, 5 are enclosed in a two-part mould S, S<SP>2</SP> with injection aperture 7 and spew outlets 8 to 11. Material injected through the aperture 7 flows through the mould and through the outlets 8 to 11 until traces of the insulation 4, 5 are seen whereupon injection ceases. Secondly, Fig. 2 (not shown), a large cable is enclosed in a polythene tube and one end of the tube enclosed in a mould so that injected material bonds to the end portion of the tube and the cable insulation only and the procedure is then repeated at the other end of the tube which forms part of the moulded joint. In this embodiment two injection apertures and no spew outlets are provided, the material being alternately injected into one aperture and discharged through the other. Thirdly, Fig. 3 (not shown), two ends of a tube having recessed between them a sleeve are enclosed in a mould with two injection apertures and four spew outlets. In this embodiment one injection aperture is plugged alternately and the material issues from the spew outlets. The materials of the articles and injected material are preferably the same and may be polythene, polyvinylchloride, polystyrene or polyamide. Ceramic, glass, polytetrafluoroethylene or " Perspex " (Registered Trade Mark) moulds may be used.
