Title: Method and apparatus for welding helically wound tubing
IPC: B21C37/12
Filed: 1960-04-19
Abstract: 920,075. Making helically jointed tubes; coiling; welding by pressure. AMERICAN MACHINE & FOUNDRY CO. April 19, 1960 [May 5, 1959], No. 13703/60. Classes 83 (2) and 83 (4). In making metal tubing a metal strip is wound helically to form successive convolutions and the edges of the convolutions are welded together by applying current of a frequency of at least 100 kc/per sec. to heat the edges. A hollow block 10 secured to a bed 11 carries a drum-like portion 14 of a mandrel 15 having a flange 16 bolted to the block and the mandrel extends beyond the block as a portion 17 of reduced diameter, this portion being truncated to provide an oval face 19 in a plane parallel to the line of advance of the metal strip. A tubular cage 22 surrounds in spaced relation the mandrel portion 17 and has flange 24 bolted to the block and has a slot 25 to receive the strip. The strip is fed by pinch rolls through an enclosed guide 29 formed by upper and lower plates 30, 31, Fig. 3, and enters the space between the mandrel and cage, one edge being guided by an angular face 21 formed by a notch 20 in the mandrel portion 14 and the edges are caused to overlap by a cam 41 engaging the trailing edge with a curved surface angular to the line of advance and adjustably bolted to the mandrel. Contacts 35, 36 connected to a source of currant of frequency 100- 500 kc/sec. slidably engage the edges of the strip in advance of the point of overlap to heat them to welding temperature and at or just beyond the weld point the edges are pressed together by ceramic or ceramic coated steel rollers 46, 47. The upper roll 46 is driven by a shaft 49 and the inner roll 47, parallel to the oval face 19, is driven by a shaft 50 passing through a hole in the mandrel. A plug is secured to the end of the mandrel beyond the roll 47 to guide the tube. An hydraulic cylinder 59 controlling the movement of a slide 60 carrying a slide 57 in which the roller shaft 49 is mounted is actuated if the power supply fails to lift the slide and roller 46 clear of the strip. Specification 853,673 is rereferred to.

Abstract: 818,670. Variable microwave impedance networks. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. May 10, 1956 [May 12, 1955], No. 13774/55. Class 40 (8). A device for providing a variable impedance at microwave frequencies comprises a waveguide or coaxial line hybrid coupler in which two conjugate limbs are each shortcircuited by plungers which may be moved to vary the phase and magnitude of the wave reflected by the plungers into a third limb. The actuating system comprises a pivoted arm for each plunger, one arm being pivoted to the free end of the other. The hybrid coupler may be in the form of a " ratrace," a 3db. directional coupler or a magic-T as shown. If the plungers (not shown) are positioned equidistantly from the junction in each of the conjugate limbs 1, 2, energy introduced into the H-arm will be totally reflected back into that arm. If the plungers are moved in unison towards or away from the junction, the phase, but not the magnitude, of the energy reflected into the H-arm will vary. If the plungers are moved equal distances in opposite senses towards and away from the junction, the magnitude, but not the phase, of the energy reflected into the H-arm will vary. The plungers may be moved by means of a pair of racks 5, 6 which engage pinions 10, 16 of equal size independently rotatable on an axle 9. The pinion 10 is rotated by a link 7 and the pinion 16 by a link 8 pivoted on the end of link 7 and coupled to the pinion 16 by a train of gears 12, 13, 14. To ensure equal displacement of the plungers for equal angular movement of the links the wheels 12, 14 are of equal diameter. The diameter of gears 10, 16 is chosen so that one complete revolution of either gear moves its associated plunger through a half wavelength. The end of the axle 9 may be positioned in the centre of a Smith Impedance Chart, Fig. 4, in such a manner that a radial line drawn from the centre to the tip P of the link 8 represents the phase and magnitude of the reflected wave. For a reflection coefficient of unit magnitude the tip P extends to the edge of the chart. Changes in wavelength may be accommodated without re-setting the chart by means of the linkage of Fig. 5 in which the connecting-rod 4 of the rack 6 is connected to the plunger 21 through a lever 22 whose fulcrum 23 may be adjusted in directions both parallel and perpendicular to the waveguide 2.

Abstract: 1313044 Recording-apparatus LABORATORY DATA CONTROL Inc 7 May 1971 [21 Aug 1970 4 Feb 1971] 13822/71 Heading G1J [Also in Divisions G4 H2 H3 and H4] In a graphical recording system an analog trace 2 of an electrical input signal e is marked on a chart 1 and a function e p  of the signal e is converted into electrical pulses of an analogous repetition rate f by a voltage to frequency converter 29 connected to a driving circuit 28' which produces a modified wave form to feed to a motor 28 connected through a cam 27 to a marking element 23 to mark an oscillating integrator trace 22 along a portion of the chart 1. A null-balance potentiometric recorder is used comprising a servo motor 8 to drive a marking element 3 and wipers of balancing and transmitting potentiometers 11, 12 whereby the ordinate p of trace 2 represents e 1  and a linear function thereof is fed to inputs 30, 31 of the converter 29. Between the input and output terminals 31, 33 of the converter 29, Fig. 4, a transistor 61 is connected as a constant current element with transistors 62, 63 as amplifier stages and a transistor 64 as emitter follower stage, a feedback to the output of transistor 61 through a timing capacitor 71 determining the repetition rate f in conjunction with the collector current of transistor 61, preset by adjusting an emitter resistor 70. A temperature-compensating diode 86 is connected adjacent input 30. The pulse output terminal 33 is connected to a counter 34 and magnetic recorder 35 and through a small capacitor 84 to a squarewave multivibrator comprising alternately conducting transistors 65, 66 coupled to the bases of output stages 67, 68 to drive the stepping motor 28'. The cam 27 is shaped to displace the element 23 linearly in proportion to the angular displacement of the cam so that the number of oscillations of the wave 22 traced is proportional to the area under the trace 2. With a motor 28 arranged to advance a fixed increment for each pulse the wave 22 is traced in steps and counting of the oscillations and fractions thereof is facilitated if (a) the amplitude of the wave 22 is made to correspond to ten steps Fig. 2 (not shown) and (b) a cam with a plurality of lobes is used with at least one having a distinctive shape to accentuate the corresponding cycle of the wave, Fig. 5 (not shown).

Abstract: 310,977. General Carbonalpha Co. May 4, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Carbon.-In producing carbon by catalytic decomposition of carbon monoxide or gases containing it, carbon obtained by the reaction is employed as catalyst. The temperature used may be 300-500‹ C., preferably 400‹ C., and pressure may be employed. As low a temperature as possible is used at the start so as to give a very active catalyst. The reaction may be commenced by means of an extraneous catalyst, e.g. iron oxide, which may be fixed or dispersed in the gas treated, and the gases thereafter maintained at a temperature favourable to the catalytic action of the carbon. In one method, brown coal, wood, peat, &c., is distilled and the charcoal or coke obtained worked up to producer gas which is cooled and, preferably after desulphurization and electrostatic purification, decomposed according to the process. The treated gas containing carbon dioxide and undecomposed carbon monoxide is returned to the generator to give further carbon monoxide for the reaction. The carbon obtained may be used as a pigment in the preparation of rubber, ink, varnish &c., as an absorbent or decolorizing medium, or as a motor fuel.
