Abstract: 641,657. Determining physical qualities and dimensions of materials. LAWSON, D. I., FULLER, D. Q., and PYE, Ltd. May 17, 1947, No. 13329. [Class 37] Apparatus for detecting flaws or other variations in electrically conducting pipes consists of a rotating or reciprocating search member which is caused to operate adjacent to the surface of the body under test so that variations in the magnetic or electric field may be detected. In one embodiment, Fig. 1, for insertion inside a pipe of magnetic material, the magnetic circuit, shown dotted, includes a rotatable search arm 1a driven by a motor 4 through a magnetic spindle 3, and is completed by the wall of the pipe (not shown). Energization is caused by D.C. in a coil 8, or the system may be permanently magnetized, and variations are shown by a pick-up coil 9. The search member 1, which may contain one or a plurality of arms, is rotated at a high speed compared with the rate of traverse along the pipe. By using lateral reciprocating motion, the search member may be used to explore other shaped bodies, with for example a U- shaped cross-section. Analysis of the pick-up signal allows for separation of the various types of irregularities causing the signal. In another embodiment, Fig. 4, the rotating search arm 11 carries one plate 10 of a condenser, the other plate being the wall of the pipe which may be of magnetic or non-magnetic material. Variations in capacity caused by irregularities in the pipe are used to modulate an A.C. voltage applied to the grid of a valve, and may thus be detected.

Title: Improvements in and relating to methods of welding
IPC: B23K9/00
Filed: 1942-09-28
Abstract: 560,061. Toothed gear wheels. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 28, 1942, No. 13600. Convention date, Sept. 29, 1941. [Class 80 (i)] [Also in Group XXII] In welding plates and a stiffening rib to each other and also to a rigid support member, the edges of the plates are fusion welded to the support member and the sides thereof are fusion welded to the side edges of the rib which is located between them so that one end is spaced from the support member, a joint member is interposed between the end of the rib and the surface of the support member so that the end portions of the joint member are spaced from the support member to form tapered gaps therebetween and are capable of deflecting to accommodate weld contractions, and the end of the rib is fusion welded to the mid-portion of the joint member and the assembly completed by attaching the opposite ends of the joint member to the support member by fusion welds which span the aforesaid gaps. Contraction strains due to the rigidity of the assembly, when the final weld is effected between the rib and support member are thus reduced before and during annealing of the assembly and cracked welds at this joint are thus avoided. Wheel-like structures such as toothed gear blanks, for use as part of a reduction gear for connecting high speed turbines to low speed propellers, or rotors for dynamo-electric machines may thus be made. A number of discs 12 .. 15 are, preferably after preheating, fusion welded at their inner and outer edges respectively to the forged steel hub 10 and forged steel rim 11 of a toothed gear blank, the edges being reduced in thickness on one side to provide grooves for weld metal, the other side being fillet welded. Yieldable lips are thus provided to take up contraction strains. The hub has a central enlargement to facilitate location of the discs 13, 14. Between the discs are fusion welded thereto the side edges of groups of radial stiffening ribs 16, 17, 18. The ribs are cut away in staggered form on opposite sides except at the ends, and the cut away portions of ribs on opposite sides of the same disc are also staggered so that the welds may yield to accommodate contraction strains. Some of the welds may be effected through openings 19 in the discs. The ends of the ribs, preferably prior to assembly of the parts, are fusion welded at 23 to joint members 22 of shape so as to leave, when assembled, tapered gaps between their under surface and the surface.of the hub. A flat member 22 would be used to co-operate with a curved hub surface or a curved member with a flattened hub surface. The member 22 is then fusion welded to the hub at 24 across the tapered gaps so that contraction strains may be provided for. The parts are machined before assembly and the outer edges of the discs tapered. Welding may be effected by the electric arc or other fusion welding process. The discs have staggered openings 20 for drawing oil from the interior.

Abstract: 628,901. Frequency modulation. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 21, 1947, No. 13661. Convention date, June 25, 1946. [Class 40 (v)] In a resonant circuit in which the tuning is varied by means of a capacitor in series with a variable resistor, the resistor comprises a diode, metal rectifier or other device not having a control grid, the current through which is controlled by a series-connected grid controlled tube. As applied to a frequency-modulated oscillator, the two halves of the tank circuit 17, 18, 19 of a push-pull pair of oscillators 1, 2 are shunted by circuits comprising effectively capacitor 21 in series with diode 22 and resistor 26 in parallel, and capacitor 24 in series with diode 23 and resistor 27 in parallel. The reactances of byepass capacitors 34, 35 are negligible at the operating frequency. The value of resistor 26 is such that the impedance of 26 and diode 22 in parallel is equal to the reactance of capacitor 21 at the unmodulated frequency of the oscillator. Resistor 27 is similarly chosen. The internal resistances of the diodes are varied in accordance with the modulating signal at 32 by passing the anode current of the amplifier 28 through them. According to the Specification as open to inspection under Sect. 91 the variable resistor may be a carbon microphone. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in electric signalling apparatus utilising the principle of the wheatstone bridge
Filed: 1922-05-15
Abstract: 181,692. Schneider et Cie. June 15, 1921, [Convention date]. Order apparatus.-In apparatus of the wheatstone-bridge type, resistances are cut in and out of the galvanometer circuit to make its deflexions proportional to the difference in setting between the transmitting and receiving pointers. In an example, the galvanometer N, Fig. 1, is in series with the resistances KJ, LM, which may be of the form shown in Fig. 2, more or less of which are included according to the setting of the pointers FG, HI on the bridge resistances AB, CD. In a modification, Fig. 3, a differential voltmeter T1T2 is employed so arranged in connection with resistances J1K1, J2K2, L1M1, L2M2, that the sum of the currents in its coils is constant for a given difference in setting between the receiver and transmitter. In this case two sliding contacts F1G1, F2G2 and H1I1, H,T, are used at the two stations held together mechanically 180‹ apart. The resistances JK, LM, may be similar to that shown in Fig. 2. In a further modification, the three resistance coils are closed, the potentiometer being fed at points < 180‹ apart, and leads from the compensating resistances being taken from points on the diameter bisecting the sectors of the potentiometer and farthest from the f.eeding points. Where desired, as in gun-laying, a normal displacement between the pointers at the two stations is obtained by displacing at either station the potentiometer and compensating as a whole relatively to the framework carrying the movable contacts. Several transmitters and receivers may use the same line by the use of distributors as described in Specification 132,756. Specification 131,635 also is referred to.
