Title: Improvements in method of producing composite metal tubing
IPC: B21C37/15
Filed: 1968-06-17
Abstract: 1,224,625. Making composite tubes; welding by pressure. REVERE COPPER & BRASS Inc. 17 June, 1968 [16 June, 1967], No. 28741/68. Headings B3A and B3R. [Also in Division F2] Composite metal tubing is produced by positioning tubular components 11, 12 of dissimilar metals concentrically within each other and within an outer restraining tube 13 having a lower coefficient of expansion than that of any of the components 11, 12, and mechanically working the assembly to reduce the wall thickness thereof, after which the assembly is heated at 750-950 F. for at least 1 hour in an inert atmosphere to cause the tubular components 11, 12 to bond together whereafter the restraining tube 13 is removed. The heating step causes the components 11, 12 to expand and move longitudinally relative to each other thereby exposing oxide free areas and causing the tubes to be bonded together. A steel plug or mandrel 14 may be inserted into the assembly which is rolled or drawn 25-30% reduction in wall thickness. The tubular components 11, 12 may be of aluminium and stainless steel and the restraining tube 13 of mild steel.

Title: Method of and means for eliminating disturbing noises in the optical reproduction of sound records
IPC: G11B7/00
Filed: 1927-10-28
Abstract: 288,225. Siemens & Halske Akt.-Ges. April 9, 1927, [Convention date]. Optical apparatus and records.-To eliminate ground noises in the reproduction of photographic ,sound records, the non-recorded part of the record is shuttered, either in the recording or the copying process, up to the envelope of the sound trace, particularly at the parts of the trace of small amplitude. This may be effected, according to one method, by covering the transparent portion of a positive made from a negative with a non- transparent colour up to the envelope of the trace. Alternatively the negative record may have the blackened part removed, by known reducers, up to the curve enveloping the record so that on making a positive therefrom only the part within the envelopo remains unblackened. Another method consists in apply a mark s, Fig. 7, corresponding to the envelope to a positive film made from a negative and again exposing to light. The resulting record according to the invention is shown in Fig. 2 wherein the envelops embracing the sound trace is the only part through which light can pass in reproducing. In another method, which avoids the necessity for additional blackening of the record, provision is made for automatically actuating a shutter from the record during reproduction so that light passes only through a width corresponding to the envelope of the sound trace. In this arrangement a beam from a source l, Fig. 9, directed through the record on to a cell z is variably intercepted by a shutter m, n, Fig. 10. comprising a fixed plate m and a plate n provided with an inclined edge and movable towards and away from the plate m by a pivoted lever q actuated by an electromagnet r in the circuit of a selenium cell p influenced by a beam directed through the record. This beam is spaced along the record o at such a distance from the reproducing beam that the lag in the circuit of the electromagnet r is compensated. The arrangement of Fig. 9, can be used in recording by substituting an auxiliary microphone for the cell p in the electromagnet circuit.

IPC: B21D11/06
Filed: 1958-09-09
Abstract: 854,023. Coiling; rolling. CROSS MANUFACTURING CO. (1938) Ltd. Sept. 9, 1958, No. 28882/58. Class 83 (4). A machine for coiling or otherwise treating wire or metal rod between two, or two sets of, rotary elements having coacting surfaces, one of the elements comprising, for example, a mandrel into which the wire is coiled, is characterized in that both sets of the rotary elements are driven and that the driving means for the same includes a differential gear in which a driving input is divided differentially into two outputs, and the latter are drivingly connected to the respective rotary element sets so as to obviate or substantially minimize slip between the two sets and between them and the wire treated therebetween. An electric motor 9 drives through change-speed gear 8 and shafts 26, 27, a crown wheel 18 of a differential gear 7. One output shaft 21 of the differential 7 drives, through chain and sprockets 23, 6 a mandrel 3, on to which wire is coiled as described in Specification 837,756, to which reference is made, by rollers 4 driven from the other output shaft 22 of the differential 7 by chains and sprockets 25, 5. The two rollers of the machine for rolling wire or rod described in Specification 748,805, to which reference is made, may each be driven by an output shaft of the same differential gear. Each pair of rollers used in making split rings as described in Specification 854,009 to which reference is made, may likewise be driven by an output shaft of the same differential gear.

Title: Improvements in or relating to variable tuning condensers
IPC: H01G5/38
Filed: 1926-11-16
Abstract: 271,400. Danielson, E. G. May 24, 1926, [Convention date]. Condensers have a drive connection between a control shaft and a pair of relatively movable electrodes and means for varying the minimum capacity between the electrodes without effecting an adjustment of the central shaft. Each electrode consists of a number of plates 10 rotatably mounted on spindles 11 on an insulating base 12, and the two are oppositely rotated by means. of meshing gears 18 from a control shaft 19. The drive connection comprises a cam 27 on the latter provided with a cam groove 28 of a contour such as to give the necessary movement to the electrodes, the groove engaging a pin 29 on a lever 23 which is pivoted at 24 to the base 12 and has a connection 26 with one of the gears 18 so that the latter are rotated by rocking movement cf the lever. The connection 26 is such as to enable the minimum capacity position of the condenser to be varied without affecting either the law, or the maximum capacity of the condenser, or the range of movement of the control shaft 19. Thus, both the lever 23 and gear 18 have slots 31, 32 to receive the pin 33 which is adjustable (Fig. 6) by means of a screw 40 along the slots against the action of a spring 41, the screw 40 being mounted in a plate 37 on the gear. The slots are so arranged as to be aligned in the maximum position, so that movement of the screw 40 has no effect on the electrodes. However, in the minimum position, they are at an angle to one another so that movement of the screw causes, rotation of the gear 18 and hence a change in the minimum capacity, the lever, cam, and control shaft remaining fixed. A friction device in the form of a spring 44 prevents undesired movement of the electrodes by pressing on the cam by means of a screw 45, and a connection to the spring may be used for earthing the cam, shaft, and lever.

A lantern body especially for spotlights and similar fittings producing a directional beam, comprises a front wall having a lens or window, an opaque rear wall and double side walls extending between the end walls, the side walls being spaced apart and provided with offset apertures which allow free circulation of convection currents caused by the heat of the lamp but prevent emission of light. The walls are spaced apart substantially uniformly around the fitting and the space between them is substantially free from obstructions which would interrupt the smooth flow of air currents and produce abrupt changes in their direction of flow. The lantern body may be in the form of an octagonal prism having outer walls 6 with gaps 8 and inner walls 7 with gaps 9 offset from these, the walls being connected by nuts and bolts 11 carrying spacing members 10. The lantern may be mounted in a U-shaped yoke 21 carried by a main support 22 for adjustment in two directions and the lamp may be adjustable relative to the lens as described in Specification 847,531.
