Title: Improvements in or relating to the manufacture of tubing
IPC: B21C37/09
Filed: 1957-05-13
Abstract: 802,997. Making seamed tubes; angular bending; brazing. BUNDY TUBING CO. May 13, 1957 [May 21, 1956], No. 15033/57. Classes 83 (2) and 83 (4). A method of making tube comprises forming moving strip transversely to form a tube with overlapping portions, feeding bonding metal inside the tube, passing the tube through a heating zone with an edge of the overlap at the bottom so that molten bonding metal enters and flows throughout the interfacial area after which the bonding metal is solidified. Strip 2, Fig. 1, e.g. steel or the metal known under the Registered Trade Mark " Monel," from a coil 1 is curled transversely about an arbor 12, Fig. 3, through 720 degrees in a roll-mill 30 to form a tube having an outer ply 4, an inner ply 5, and a seam 10 with interfaces 8 and 9, Fig. 2. The trailing edge of the strip is temporarily flanged at 11 to resist the compression forces due to the lateral movement to effect curling round the arbor. The arbor makes contact with the inside of the tube only at the point where final rollers 15, 16 bring the interfaces into tight engagement. Bonding metal 21, e.g. copper, copper alloy or other suitable hard solder in wire form is drawn from a coil 20 into a passage 18 through the arbor 12 and into the tube. Alternatively the bonding metal may be powder or fine particles which are forced through the passage 18. The tube 3 is then passed through a furnace 25 having a non-oxidizing or reducing atmosphere and heated by current from electrode rollers 26, 27, 28 connected as shown to simplify insulation of the apparatus. Molten bonding metal is thereby caused to enter the interface at 8 and flows circumferentially throughout the interfaces. Finally the tube passes through a cooler 42.

Title: Improvements in or relating to sine-cosine voltage generators
Inventor: MCDERMOTT TERENCE JOHN
IPC: G01S7/12
Filed: 1949-06-08
Abstract: 679,723. Phase measurement; current and voltage measurement. DECCA RECORD CO., Ltd. July 26, 1950 [June 8, 1949], No. 15319/49. Class 37. [Also in Group XL (c)] The invention relates to a combination of two circuits for producing D.C. voltages respectively proportional to two A.C. voltages which respectively represent in amplitude and polarity the sine. and cosine of an angular position. In each circuit the A.C. voltage is used to amplitude modulate short duration pulses which occur in synchronism with the A.C. voltage and the required D.C. voltage is derived from the pulses. The modulation may be achieved by adding to the A.C. voltage short pulses 11 of constant amplitude, preferably at the peak of the cycle and the D.C. voltage may be obtained from the portion of the pulse above a datum level 12. Alternatively, in the circuit shown, positive pulses applied to the grid of a triode V1B raise the corresponding cathode potential rendering a diode V2B conducting and applying a pulse to the grid of a valve V3. When the diode anode potential reaches the potential of the cathode of a triode V1A a diode V2A conducts and prevents any further rise of D.C. output pulse. The potential of the cathode of VIA and thus the peak value of the pulse applied to the grid of valve V3 depends on the instantaneous value of the 1000 c/s. A.C. voltage applied to the grid of valve V3. A D.C. restorer diode V4 is connected to grid of V3 and the grid is biased beyond cut-off so that only the peaks of the pulses render the valve conducting. The anode current pulses are integrated in a circuit R10, C3 and the resulting output is applied to a cathode follower stage V5. The D.C. output of the cathode follower stage is applied as negative feed-back to the grid of the input triode V1A and this reduces distortion and obviates the necessity of ensuring that the amplitude of the applied pulses is greater than the peak-to-peak value of the A.C. wave input.

Abstract: 1500383 Rotary lapping device SIEMENS AG 16 April 1975 [19 April 1974] 15760/75 Heading B8G A rotary lapping device, for applying elongate cover material around an elongate member as it moves longitudinally relative to the device, comprises a rotary carrier member for the cover material, a rotary flyer for unreeling cover material from the carrier, and a monitoring arrangement for monitoring the speeds of rotation of the carrier member and flyer comprising a first monitor coupled to the flyer for rotation therewith, a second monitor coupled with the carrier member for rotation therewith, and third and fourth monitors fixed in the device and cooperable with the first and second monitors for generating signals dependent on the speeds of the flyer and carrier member. As shown, flyer 11, 12, 13, 15 is rotated by gear 14 to unwind material 22 from supply 21 and wind it about a core running through the centre of the device. Supply 21 is mounted on member 20 rotated by flyer member 15 via permanent magnet 16 and disc 25. The radial teeth of rotating gear 14, and of gear 26 rotating with member 20, produce a pulse-wire variation of magnetic flux in fixed sensors 31, 32 which include permanent magnets, and the sensors transmit pulsed electric signals which are counted in separate counters. After a predetermined number of pulses the counters transmit signals which are compared. If the signals correspond the flyer and member 20 are rotating at the same speed and the device is working incorrectly, and a signal is transmitted to stop the winding or to trigger an optic or acoustic signal. Alternatively, the sensors 31, 32 may be opto-electrical transducers and the gear-wheels replaced by perforated or toothed discs, e.g. the discs having the same number of teeth or perforations.
