Abstract: 1,109,862. Arc-welding supply systems. UNION CARBIDE CORPORATION. 12 May, 1965 [13 May, 1964], No. 19967/65. Heading H2H. [Also in Division B3] To reduce spatter in arc welding of the shortcircuiting, metal transfer type, a control unit is added to conventional power supply apparatus to reduce the current substantially below the arcing value when short-circuiting of the electrode and workpiece occurs. The Figure shows a control unit 42 interposed between a D.C. supply 67 and an electrode/workpiece combination simulated at 69 by a load 71 and switch 73. With the latter open, application of the D.C. supply fires silicon controlled rectifier 59 to produce a steady current (equivalent to the arc current) through load 71 and allow charging of a capacitor 65. Closure of switch 73 (short-circuiting of electrode and workpiece) fires the controlled rectifier 57 to discharge capacitor 65 and so cut off the rectifier 59, thereby inserting the adjustable resistor 61 in the circuit to reduce the current to a predetermined value. The cycle is sequentially repeated during the welding operation. The spatter control unit may be connected in the D.C. or A.C. side of the welding supply system with appropriate connections to the electrode and workpiece in the A.C. case, Figs. 1 to 5 (not shown). Typical volt/amp output characteristics of the various systems are illustrated and discussed, Figs. 6 to 9 (not shown).

Filed: 1951-08-25
Abstract: 766,531. Stuffing-box substitutes. GODFREY (HANWORTH), Ltd., [formerly GODFREY & PARTNERS (HOLDINGS), Ltd., Sir G.]. Aug. 25, 1952 [Aug. 25, 1951], No. 20066/51. Class 122 (5). [Also in Group XXXIV] A high-speed compressor and turbine unit has rotors 10, 11 mounted upon end portions of a shaft 14 provided with ball-bearings 23, 24 lubricated by means involving screw-threads 31, 32 of opposite hand (see Group XXXIV) and means are provided for preventing oil fed through the bearings from passing radially outwards along the backs of the rotors. Each of the rotors has a sleeve 40 with a radial flange 40a which has two inwardly-projecting flanges 41, 42. These flanges are circumferentially grooved and are a close fit against surfaces of the casing or of bushes fixed thereto. The arrangement is such that as the shaft 14 rotates a flow of air passes from the periphery of each rotor back along the grooved surfaces to an annular space 49 and eventually to atmosphere along channels 50, thereby preventing oil flow in the opposite direction from each bearing. The part of the shaft between the screw-threads 31, 32 is circumferentially grooved at 39 to prevent oil passing directly between channels 29, 30.

Title: A method and apparatus for inductive automatic testing of material for irregularities
IPC: G01N27/90
Filed: 1956-06-29
Abstract: 843,775. Determining physical qualities of materials. SVENSKA METALLVERKEN A. B. June 29,1956 [July 1, 1955], No. 20288/56. Class 37. In a flaw detector in which the material to be tested is passed at a predetermined speed through a test zone in which an alternating magnetic field is produced at a predetermined fundamental frequency, the passage of a flaw in the material to be tested generates a fault signal which modulates the fundamental frequency so that a modulated signal is produced from which a pulse substantially free of the fundamental frequency is derived the pulse being utilised for control purposes. Fig. 9 shows a test apparatus in which the material, for example electric wire, to be tested for flaws is passed at a predetermined speed through coils 26, 27 which form with the secondary coils 29, 34 of the screened and balanced transformer 11 an A.C. bridge circuit to which a fundamental test frequency is applied from the oscillator comprising double triode tube 58 and the amplifier tube 44. The presence of a flaw or lack of homogeneity in the material to be tested causes a modulation of the output voltage from the bridge, as shown in Fig. 4. This voltage is amplified in the tuned amplifier comprising tube 88 the anode circuit of which is broadly tuned to amplify either a modulated or unmodulated unbalance voltage. The output from the stage is rectified by diode 109 to produce an unsmoothed D.C. current indicated by instrument 111 proportional to the amplitude of the alternating voltage applied. For continuous operation the switch is changed to make contact with terminal 113 so that in the presence of a fault the rectified modulated signal is filtered in circuit 17 to produce a fault pulse as shown in Fig. 6. This signal is amplified by tube 123 and applied via potentiometer 138, which is adjusted in dependence upon the dimensions of the material under test, to amplifier comprising tube 141 which is tuned to the modulation frequency. The Q of the tuned circuit allows variations in the speed at which the material is fed into the test coils without any appreciable change in the amplification. The amplified output pulse from tube 141 triggers thyratron 160 to fire it and operate relay 167. Energisation of the relay 167 causes fault indicator lamp 174, or an associated aural indicator, to be energised and stops the electric motor which feeds the material to be tested into the test coils 26, 27. The sensitivity checking device 25, 32 operates in the same way as do coils 26, 27 in conjunction with the faulty wire and permits the sensitivity to be checked from time to time. The magnitude of the D.C. current indicated by instrument 111 enables the degree of unbalance of the bridge to be determined by means of the adjustable capacitor 36. In a modification the fault impulse is derived from phase modulation of the fundamental frequency which occurs as a phase rotation due to the passage of the flaw. The detector shown, in Fig. 9 is then replaced by a phase discriminator.

Abstract: 379,816. Making window guides ; pendulum saw machines. REID, J. S., 14122, South Park Boulevard, Shaker Heights, Ohio, U.S.A. July 20, 1931, No. 20729. [Class 20 (iii).] A machine for the continuous production of covered metal window guides such as are used in motor vehicles comprises driven feeding rolls 32, Fig. 1, by which the metal ribbon is drawn from one of the braked coils 10, 10a through a spot-welding device 11 thence to a compensating mechanism 12 consisting of fixed pulleys 19 and a vertically movable weighted carrier 21 with pulleys 20. The ribbon passes from the compensator through a rubber extruder 24 and then through a water cooling trough 26 after which it receives an air blast in the tube 29 to remove excess water. The rubber coated metal is next fed through a second compensator 34 to an adhesive coating device 36 after which a felt strip from one of the rolls 39, 40, Fig. 2, is applied thereto by the rolls 43, a funnelshaped folder 44 and pressing springs 45, 46, Figs. 2 and 7. The strip then passes through feeding and pressing rollers 47, to geared shaping rolls 48 and is delivered with or without an additional feeding device to a cutting-off machine. The latter comprises a pendulum saw 63, the carrying frame 60 of which, Fig. 9, is reciprocated by air pistons or the like 69. The saw spindle is splined in a sleeve driven by chain 65 and motor 58 and is moved with the work when cutting by the weighted bell-crank 86 and a double cam 85. The saw is held out of action by a latch 77 and a recess 76 in each end of an arcuate arm 75 on the frame, the latch being released by a spring-controlled rod 77a, an adjustably positioned rod 83 thereon and a trigger lever 83a actuated by the outcoming end of the channel. The main drive of the machine is given by a two speed motor 92 with a variable speed gear, Fig. 12, for the later operations of covering the ribbon &c. The gear which is driven through a clutch 98 is regulated to increase or reduce delivery by a motor 111 and reversing switch gear 113, 114 and contacts 35a, 35b, said contacts being carried by the movable member 35 of the second compensating device which rises if delivery increases and falls if it diminishes. When it is necessary to feed from a new reel 10, 10a the end is retained in the spot-welding device by an eccentric clamp 15, Figs. 1 and 10, while the new end is threaded through the guide 11a and welded &c. During welding, movement of the carrier 21 supplies ribbon for continuous working. In order to join up a new end of felt, the carrier 35 is caused to rise by a switch 150 thrown in parallel with the points 114. The clutch 98 is then disengaged and the splice effected by hand at the rolls 43 ; normal working is then restored. The fall of carrier 35 absorbs material from the earlier operations during the splicing of the felt.
