Patent GB-1219865-A (GB)
Title: Method and apparatus for controlling a fusion welding process
Inventor: KAZENNOV JURY IVANOVICH
IPC: B23K9/095
Filed: 1969-03-13
Abstract: 1,219,865. Welding by fusion. J. I. KAZENNOV, V.A. VINOGRADOV, V. S. POPENKO and L.T. SOLODKIN. 13 March, 1969 No. 13296/69. Headings B3R. [Also in Divisions G1 and G3].  An arc welding process is controlled in accordance with measurements of the weld composition produced by a spectrally sensitive radiation detector. When butt welding dissimilar materials departures of the weld from the joint show as changes in weld composition. In the case of lap joints of dissimilar metals or a butt joint with a dissimilar backing strip, composition changes indicate changes in penetration. In a gas-shielded welding process, Fig. 6, the metals to be welded are placed on a strip 18 having a groove 19 through which is passed an antioxidant gas different from that shielding the welding zone. The concentration of antioxidant gas in the weld atmosphere falls off away from the joint, and provided photo-cells 13, 14, which are connected in a bridge circuit, are symmetrical about the joint the bridge will balance. Imbalance of the bridge actuates a motor, by means of a multivibrator acting as a D.C. to A.C. converter, to return the electrode to the centre of the joint.

Abstract: 150,065. Owen, W. H. May 27, 1919. Forced-draught systems; regenerators.-In a forced-draught system for furnaces in which the air is heated by the products of combustion, air is supplied by a blower to a tubular or other regenerator B from which part of the air passes direct to the furnace ash-pit and the remainder to a second regenerator A exposed to gases of a higher temperature. The more highly heated air escapes from the regenerator A to the space above the grate through pipes g<1>. Fig. 2 shows a modification in which the two air heaters A, B are arranged in a single structure above the smoke box of a boiler, the heaters being separated by a partition A' having openings controlled by dampers to admit air from the heater B to the heater A which is exposed to gases at a higher temperature.

An electrolytic cell apparatus, for the continuous measurement of the fluoride activity of an aqueous acidic fluoride containing solution, as described in the parent Specification is modified by the addition of a second inert electrode 8 (as shown) provided to facilitate cleaning of the measuring electrode 7. During a measuring operation a p-type silicon anode 6 and the first inert platinum electrode 7 acting as a cathode, are connected to a D.C. source 9. A time switch arrangement 13 disconnects the supply from measuring electrodes 6, 7, for about 10 secs. in each half-hour operation, and connects the D.C. voltage across electrodes 7, 8, so that the electrode 7 is now positive and gas will be evolved thereat which tends to break up and carry away any objectionable film thereon.

An apparatus for forming a bunched strand by means of a double twist bunching machine 1, is characterized in that the input to the machine 1 is via haul-off devicd 2 mounted for axial rotation and adapted to draw the elements from a stationary supply and feed them as a rotating bunch towards the bunching machine, the device 2 rotating in the same direction as the flyer of the machine 1 but at a greater speed such that at least a substantial proportion of the twist of the finished strand is put in prior to its entry into the device 2. In Fig. 1 the device 2 is a rotating housing carrying endless belts 12 between which the bunched strands are gripped and fed to the machine 1. The optimum running condition is that in which the device 2 rotates at twice the speed of the machine 1. Under this condition there will be +2 twists per unit length at the die 7; - 1 twist per unit length at the flyer entry; and +1 twist at the flyer delivery, giving a final result of 2 twists per unit length. It is within the scope of the invention for this speed ratio of 2:1 to vary between 1.5:1 and 2.5:1.

Title: Improvements relating to shifting registers
Inventor: GOATCHER FRANK
IPC: G11C19/04
Filed: 1957-04-30
Abstract: 893,352. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 18, 1958 [April 30, 1957], No. 13794/57. Class 40 (9). [Also in Group XIX] A magnetic core-storage shifting register has, as shown, main storage cores 1-3 and two sets of subsidiary cores 4 and 5, and 6 and 7, which may be used selectively for shifting from left to right, and right to left, respectively. As shown, cores 1-3 have transistor input/output circuits similar to the type described in Specification 893,355, and shifting to the right or left is selected by employing either " X " pulses or " Y " pulses applied to the windings indicated at half the frequency of the "A" advancing pulses. Considering shift to the right, an A pulse will change core 1 from " 1 " to " 0 " state, thus acting through output winding 50 and transistor 44 to produce current in windings 57 and 60. The "X" pulse in winding 35 prevents resetting of core 1 to the " 1" state (it starts at the same time as, but is made longer than, pulse A to ensure this in spite of the lengthening of the output pulse achieved by condenser 65 as described in the above-noted Specification) by winding 57, but winding 36 is so arranged that it assists winding 60 to switch core 4 to the "1" state. The next "A" pulse acts to switch back core 4 to the " 0 " state and winding 53 switches core 2 to the " 1 " state through diode 69, transistor 45 and winding 58; no "X" or " Y " pulse occurring no switching of cores 5 or 7 results. Similar action to shift to the left occurs if " Y " instead of " X " pulses are supplied.

Abstract: 139,380. Ralston, S. B. May 31, 1919. Stability, determining.-Apparatus for determining the trim and metacentric height, of the kind described in Specification 11561/10, is modified by replacing the platform and weight moving over the profile diagram of the ship, by two weights e, f moving along the edges of the profile diagram. The trim is determined by the position to which the weight f must be moved to produce equilibrium when the board is pivoted on the trunnions c in conjunction with the diagram board shown in Fig. 1. The position of the weight e to effect equilibrium when the diagram is pivoted on the trunnions d determines the metacentric height. The scale s on the diagram board is set to correspond with the draught or load of the ship as indicated on the scales p, o, and the trim and metacentric heights are read off on the scale s at the intersection of the scale with the particular curve r, q indicated by the number on the scales m, l at which the trim and metacentric height sliding weights effect equilibrium.

Title: Improvements in or relating to apparatus for photographically recording sound

Filed: 1934-05-11
Abstract: 432,603. Optical sound - recording apparatus. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London.-(Bell Telephone Laboratories, Inc. ; 463, West Street, New York, U.S.A.) May 11, 1934, No. 14324. [Class 40 (ii)] In optical sound-recording apparatus employing a light valve comprising current carrying ribbons 8, 13 adapted to vibrate in a magnetic field so as to modulate a recording light beam, the ribbons are arranged to have different natural vibration frequencies which are located higher in the frequency scale than the normal range of sound frequencies to be recorded. Thus the natural frequency of one ribbon may be 8000 to 9000 cycles per second whilst that of the other ribbon is 13000 cycles per second. In order to obtain these different natural frequencies, the ribbons may be differently tensioned or mounted or may be of different materials, thicknesses or lengths. The invention is stated to minimize the distortion of the sound record, particularly at high frequencies, the device acting at low sound frequencies more or less as a doubleribbon light valve with equally tuned ribbons whilst at high sound frequencies it acts rather like a single ribbon light valve. If desired, the response of the ribbons at low frequencies may be exactly equalized by connecting an impedance 17 in parallel with the ribbon 8 tuned to the lower frequency or by using a heavier ribbon for the ribbon 8. The invention may be applied to recorders having more than two ribbons and also to recorders in which the ribbons are biassed in accordance with the loudness of the sounds to be recorded in order to produce a noiseless record as described, for example, in Specification 405,078.
