Title: Improvements in and relating to welding apparatus
IPC: B23K9/133
Filed: 1939-09-14
Abstract: 534,734. Swash-plate mechanism. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 14, 1939. No. 25800. Convention date. Sept. 16, 1938. [Class 80 (iii)] [Also in Group XXII] In an electric arc or gas-welding apparatus the electrode or blowpipe and weld rod are oscillated through a pivotal mounting, a rotatable shaft having an oblique surface carrying a pin perpendicular to the surface on which is journalled a follower with means between the surface and the mounting to convert the rotary motion of the shaft to a reciprocating motion for oscillating the mounting. An arc welding electrode 13a is fed by rolls driven by a motor 26 and change speed gear 27 through a nozzle 10 carried by contact mechanism 11, as described in Specification 533,529, [Group XXII], which is carried by a yoke 31 pivoted at 33 in a ring 14 itself pivoted at 29, 30 in ears 28 in a casing 25. Either pair of pivots may be fixed by nuts so that the electrode may be oscillated about the other pivots. For this purpose there is secured to the yoke 31 at an angle between the pairs of pivots an arm 15 which supports by a ball joint a connecting rod 16 having at its upper end a spherical head 38 engaging a groove 22 in a block 17 which is mounted on ball bearings on a pin 24 projecting from the oblique end surface 18 of a shaft 19 rotated by a motor 20 through gearing 21. The rod passes through a hole 43 in the arm 41 of an adjustable bell crank lever and the centre of the head of the pin 24 is in alignment with the axis of the shaft 19, so that the rotation of the shaft 19, causes a vertical reciprocation of the block 17 and connecting rod so as to oscillate the electrode either across or along the seam. The amplitude of the oscillation is varied by adjusting the bell crank by a threaded rod operated by a hand wheel 48. The frequency of the oscillations is varied by speed adjusting means for the motor 20. In a modification the grooved block 17 may be replaced by a smooth block against which the end of the rod 16 is held by a spring, or the block may be journalled on the bent portion of a bent shaft.

Abstract: 791,902. Linear dimension gauges. HEIDENHAIN, J., [trading as WENCZLER & HEIDENHAIN]. Sept. 9, 1954, No. 26181/54. Class 106 (2). [Also in Group XXII] A measuring means for determining the position of a body in relation to a graduated scale is characterized by graduations formed by variations in magnetic field along the scale and a scanning member movable relative to the scale and transmitting signals in response to the magnetic conditions prevailing in a particular position along the scale, the scanning member being attached to the body. In some embodiments, a magnetic head 3 scans a scale 1 having magnetic markings corresponding to the graduations (Fig. 1). The markings may be inserts of magnetic in non-magnetic material or vice versa. Two series of graduations may be arranged in vernier relation. The graduations may be arranged to vary in their magnetic effect so that the signals produced differ according to the position of the body. A magnetic tape may be used to enable vocal announcements of the body's position to be made. A further alternative consists in using electrical impulse counters to determine the position. The graduations may be directionally arranged for scanning by a series of magnetic heads having gaps positioned to respond to particular graduations (Fig. 5). The effective scale length may be increased by arranging it as a helix on a rotating cylinder, the magnetic head traversing the cylinder longitudinally. If the speed of the traverse of the head relative to the graduations is not high enough to produce the necessary variations of potential, the head may be oscillated or comprise an oscillating portion. Alternatively it may carry a coil through which an alternating current is passed. The scanning means may comprise deflector magnets traversing the graduations and so positioning the beam, or beams of a cathode-ray tube on one or more of its output electrodes as to produce a selective signal (Figs. 11, 13). A series of gaps in one or more deflector magnets may respond to variously arranged graduations (e.g. Fig. 20). Specification 607,702, [Group XXII], is referred to.
