Abstract: 1,144,288. Laminates. INTERNATIONAL BUSINESS MACHINES CORP. 9 March, 1967 [11 March, 1966], No. 11045/67. Heading B5N. [Also in Divisions G 5  and H1] A laminated structure comprises a plurality of layers of particulate magnetic material with a binder, separated by layers of particulate non- magnetic material with a binder, and sintered to form a unitary structure. Each layer may be formed separately by mixing the particulate material with the binder and a solvent, spreading it on a base, and peeling it off after evaporation of the solvent. The layers are then stacked and sintered at 1000-1500‹ C. The materials used may be a magnetic ferrite, and Pd or a non-magnetic ferrite, in a polyvinyl butyral resin binder. The structure may be cut prior to sintering to form toroids, or shapes used in making recording heads.

Title: Improvements in and relating to methods of welding and means for use in carrying the methods into effect
IPC: B23K11/30
Filed: 1941-08-30
Abstract: 551,641. Welding-electrode holder. RAKOS, A. Aug. 30, 1941, No. 11111. [Class 39 (iii)] [Also in Group XXII] In welding parts of metal such as aluminium or aluminium alloys by contacting the parts with an electrode 1 of low conductivity such as carbon, graphite or a metallic carbide heated by the passage therethrough of electric current, one part 4 of the current source is connected to the electrode and the other to both the work and to an auxiliary contact 6 in electrical connection with the electrode, so that the electrode is continuously heated even if contact with the work is interrupted. Accidental cooling of the electrode due to sinking down of the molten metal at the joint is thus prevented, and interruption of welding due to solidification of the flux with the consequent necessity for cleaning the work of electrode is thus avoided. The electrode 1 may be fixed in a holder 3 in a handle 2 connected to one terminal of the circuit, the other terminal being connected to a spring-pressed lever 5 carrying a carbon or like contact 6 engaging the electrode near one end. The circuit, which is completed through the contact 6, may be normally closed as shown, or normally open. The work 8, 9 is also connected at 12 to the second terminal of the circuit. In Fig. 2 the handle is connected to one terminal and the work to the other, the circuit being completed by the electrode 1 engaging conducting guide members 13, 14 on each side of the flanges on the work. The guide members have diverging surfaces and the current continues to flow if contact between the electrode and flanges is interrupted. In a further form wheels 17, 18 of conducting material with internal flanges 19, 20 are carried by the holder 3 and. engage the end of the electrode 1. Their distance apart is adjustable so that the height of the electrode may be regulated. The electrode is connected to one terminal of the current,and the wheels and also the work to the other terminal. The electrode may roll over the work. The contact device may in some cases be arranged to slide along and make contact with the work as the electrode is moved. The electrode may be rotated on its axis to ensure uniform wear. In Fig. 3 the rotation may be derived from the wheels 17, 18.

Abstract: 237,989. Pitt, K. May 7, 1924. Endless chain and like carriers, apparatus with; prisms and like elements, rotating.-Apparatus for changeably exhibiting pictures, advertisements, &c. comprises two endless chains a between laterally extending links b of which are suspended elements c bearing parts of the designs, which form a complete whole on the two front elements 1, 1 viewed through a window. The chains a are carried on sprocket wheels e having preferably two teeth only. One of the wheels e is intermittently rotated through a complete revolution by Geneva stop mechanism, in which four radial slots in a star-wheel are in turn engaged by pins or projections h on a constantly moving endless band i, suitably slotted to accommodate the star-wheel. The elements 2, 2 thus succeed the elements 1, 1 in the display plane d. The elements may have holes or downwardly extending fittings to receive hooks j pivoting on pins k on the links b. The hooks j may engage the elements slightly above their middle and be sufficiently long to allow the element to be guided by side ledges l during its descent in a plane not far forward of its display position. Springs m may bear on pins on the links b to hold the links upright. A number of devices as above described mav be located above one another, each being provided with Geneva stop mechanism or geared together, their elements co-operating to form a single picture &c. The casing containing the device may be rotated about a vertical axis, at intervals, through 180‹, to expose designs on the backs of the elements through a rear window. The rotation is effected by Geneva-stop mechanism actuated by pins on a disc or endless band driven by an electric motor.

Abstract: 377,195. Discharge lamps. CLAUDE, G., 3, Avenue de l'Opera, Paris.-(Assignee of Smalley, R. C. ; 66, Rutherford Place, Arlington, and Beck, L. L. ; 27, Stoneleigh Park, Westfield, both in New Jersey, U.S.A.) April 16, 1931, No. 11326. Convention date, April 17, 1930. [Class 39 (i).] Dimming of a vacuum-tube lighting system is obtained by the use of a transformer 15 with high magnetic flux and a factor of low efficiency, and having a magnetic flux shunt 21 interposed between the primary and secondary windings 17, 18 respectively wound on opposite members of the core 16 which has legs 19 and 20 between which the adjustable shunt 21 can rotate. Dimming of the tube is obtained by shunting the induced flux during the operation of the tube, the adjustable shunt being mounted on an axle 26 with handle 27. The Specification as open to inspection under Sect. 91 (3) (a) comprises also working the system on a lower power factor either by constructing the two cores of unequal crosssection to allow leakage of flux round the secondary winding or by introducing an inductance into the primary circuit, thereby ensuring longer life of the discharge tube. This subject-matter does not appear in the Specification as accepted.

Filed: 1946-04-12
Abstract: 610,655. Pulse shaping circuits. STANDARD TELEPHONES & CABLES, Ltd. April 12, 1946, No. 11333. Convention date, May 24, 1943. [Class 40 (vi)] Pulses are selected from a train according to their amplitude, leading and trailing edge slope duration and repetition frequency. In one embodiment, the pulses from input 9 are applied to four parallel branch circuits A ... D. In branch A, pulses of less than desired amplitude are eliminated in clipper 10 and the mixer 17 receives the remaining pulses and the amplified and inverted portions of those pulses exceeding the desired amplitude from circuit 15, so that undesired pulses are cancelled out. The desired pulses are then differentiated in circuit 19. In branch B the incoming pulses are clipped to a common amplitude in circuit 24 and then differentiated at 26 to produce pulses, the amplitude of which corresponds to the slope of the leading and trailing edges of the input pulses. An amplitude discriminator 27, which may be identical with that of branch A, then selects the desired pulses. In branch C, after differentiation in circuit 34, the resultant pulses are passed to a mixer 38 together with an inverted and delayed version thereof produced by circuits 35, 36, the delay being equal to the duration of the desired pulses. The mixer 38 also removes all but the double amplitude pulses corresponding to the desired pulses only. In branch C is a gating circuit 44 ... 46 passing only pulses of the desired recurrence frequency to a differentiator 51. The outputs of all the branches are combined in a mixer 70 where the resultant amplitude of desired pulses exceeds that of undesired pulses and the former are selected by a clipping circuit. In another embodiment, Fig. 4 (not shown), the selecting circuits are arranged in cascade. Specification 597,323 is referred to.
