Title: Method of and apparatus for electric resistance welding
IPC: B23K11/00
Filed: 1955-11-08
Abstract: 814,608. Welding by pressure. FRUNGEL, F. Nov. 8, 1955, No. 31854/55. Class 83 (4). In electric resistance spot welding a heavy current of short duration is passed through the workpieces by electrodes maintained in contact therewith throughout welding and the major portion of the metal melted by the current is ejected from the weld area, to effect cooling thereof, at least partly by electromagnetic forces produced by the current. In an embodiment two crossing wires 3, Fig. 1, are engaged by electrodes 6, 7 connected to a single-turn secondary 3 of a transformer 1 and pressed together by jaws 10 acting through resilient members 11. A condenser charged from a source of more than 2000 volts, preferably voltage stabilized, is connected to the transformer primary to provide a pulse of welding current. Molten metal is ejected as indicated by arrows 13 when the current pulse flows. In a modified apparatus for double spot welds main electrodes 6, 7, Fig. 2, are connected to the transformer by flat conductors 4, 5 and a pair of counter electrodes 6a, 7a together with a bridge member 12 complete the circuit. Although rubber is used as the resilient means 11 springs may be used and these means need only be on one side of the work. In a further modification two pairs of main electrodes may be arranged above two pairs of counter electrodes and the pairs of main electrodes are connected to flat conductors, the electrodes connected to one flat conductor passing through holes in the other conductor. A switch 21, Fig. 5, may be provided to ensure that the condenser 16 is not discharged until a predetermined pressure has been applied by the electrodes. When the pressure has been reached a contact 21a closes the switch to actuate a magnetically operated switch 20 between the condenser and transformer. The electrodes contact with work over a larger area than that of the contact between the workpieces and the natural frequency of the electrodes system should be high, e.g. above 100 cycles per second, to maintain the work surfaces in contact during welding. The inductance of the electrode circuit should be low, e.g. less than 1, preferably 0.1, microhenry and the current impulse should rise by 1000 amps. in 1 microsecond to eject particles with a velocity of 5 metres per second. Oxide resulting from the welding is collected. Platinum and platinum-rhodium can be welded in the manufacture of thermo elements, tungsten can be welded to contact bodies and steel wires &c. can be welded.

Abstract: 286,820. Gaydon, H. A., and Hough, T. Dec. 31, 1926. Tool-arm mountings.-The stylus-car of the sound-box of a sound-reproducing machine is so mounted and controlled that the vibrations of the diaphragm from the central position are assisted, while the return movements are damped. In the construction shown in Figs. 1 and 2, the stylusbar b is secured to the centre of a flat triangular plate c, which is held against the points of screws e by means of a wire f engaging a groove in the vertical edge at the apex of the plate c. The ends of the wire are secured to the frame a<2> of the sound-box by screws g. The wire may be tensioned by any suitable means, for example by adjusting the screws e, or by a spring-pressed or screwed pi in the edge of the plate. Instead of the wire f, a coiled spring having a plain part engaging the plate c may be used; or two separate leaf springs may be employed, each secured at one end to the frame, and at the other end engaging the plate. Fig. 3 shows a further modification, in which an oval plate c secured to the stylus-bar rests on the points of screws e, which are adjustably mounted in a right-angled extension a' of the frame a<2>. A wire f passes through a hole in the stylus-bar, and through the part a<3>, and its ends are secured by screws k to a plate h, through which the needle-carrier d passes.

Abstract: 908,561. Measuring electrically. HOBSON Ltd., H. M. Jan. 21, 1959 [Oct. 23, 1957], No. 33139/57. Class 40 (1). A fuel flow meter for providing a continuous indication of the remaining available flight time of an aircraft at the prevailing rate of flow of fuel by computing the variables of amount of fuel remaining and rate of flow, comprises a current meter, a resistor effectively connected in series therewith, means for generating a D.C. voltage proportional to one of the said variables and for applying this voltage across the series connection of meter and resistor, means for adjusting the resistor so that the combined series resistance of resistor and meter is directly proportional to the other of said variables, the calibration of said meter being such as to provide a direct reading of the remaining available flight time. As shown, Fig. 1, in a flow-meter of the general type described in Specification 752,496, pulses generated at a rate corresponding to the rate of flow of fuel by a transmitter 10 are amplified at 11, shaped at 12, and fed to a chain 13 of binary frequency dividers, the output of which is supplied to a solenoid-operated escapement mechanism 14 which operates the wiper of a helical potentiometer 16 having a linear law to apply a voltage V 1  proportional to the amount of fuel remaining in the tanks to the grid of a cathode follower valve 17. The shaped pulses are also supplied to a ratemeter 18 to adjust a rheostat R 1  which is connected in series with a resistance R<SP>1</SP>m to form the cathode load of valve 17. The voltage across the resistor R<SP>1</SP>m is applied to the grid of a second cathode follower valve 21 feeding a meter 22 of resistance Rm (R 1 +R m ) being directly proportional to the rate of flow. The meter current equals V 1 /(R 1  +R m ) and is thus directly proportional to time-to-go. In the embodiment shown in Fig. 4, the output from the shaper is fed to a network as described in Specification 851,149, comprising a differentiating circuit 29, 30 and a monostable flip-flop V 3 , V 4  associated with a diode bridge 26 energized by voltage reference neon tubes 27, 28 which also apply a constant voltage to the grid of valve 21. The square wave voltage pulses appearing across the anode load resistor 31 of V 3  are integrated at 25 to produce a D.C. voltage V R  representing the rate of flow, which is applied to the grid of valve 17, while the solenoid operated escapement mechanism adjusts a rheostat R connected in series with the meter 22 between the cathodes of valve 17, 21, so that (R+Rm) is proportional to the amount of fuel remaining. As the meter current, which equals VR/(R + Rm) is inversely proportional to the time-to-go, the meter is provided with a reciprocably calibrated dial. The Provisional Specification describes an embodiment in which a voltage representative of amount of fuel is dropped across a constant resistance and the output is derived from a portion of said resistance variable in inverse proportion to the rate of flow.
