Abstract: 354,350. Lead - in bushings. MAXWELL, K. G., Lasswade, St. Margarets Road, Bowden, Cheshire, ASHLEY, P. G., Glendevon, Raglan Road, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. May 2, 1930, No. 13509. [Class 36.] In a lead-in bushing of the type comprising a conductor 1 surrounded by layers of varnished paper or like insulation 3, a slipping surface 6, which may be formed by a layer of greased paper, is provided between the conductor and the insulation 3 to allow the conductor to expand or contract independently of the surrounding insulation. In order to prevent displacement of the conductor 1 as a'whole relative to the insulation 3, the conductor is formed with a roughened portion 5 to which the surrounding insulation is firmly attached. The portion 5 of the conductor may be roughened chemically, electrically or by knurling. To prevent ionization of air entrapped by the slipping surface 6, a metallic insertion 7, connected to the conductor 1 by flexible leads 8, may be applied over the inner layers 2 of the insulation. The bushing has an earth band 4. The electric stress in the insulation 3 may be graded by tinfoil insertions.

Abstract: 1,172,807. Adhesive tape. UNIVERSUMVERPACKUNGS-G.m.b.H. & CO. K.G. 21 March, 1968, No. 13772/68. Heading B5N. Adhesive tape comprises a resilient backing web carrying the adhesive and reinforced by elements (e.g. threads, filaments, strips or filament bundles) extending longitudinally of the tape and attached thereto, the elements being crimped and the backing web being extensible; so that the tape is extensible until the elements are straightened and has good tensile strength when in the limiting extended condition. The backing web may be a strip of transversely crimped paper, or of P.V.C. which may be elongated by 10-25%, or the web may be a laminate comprising a crimped paper web bonded to a stretchable plastics film. The reinforcing elements may be non-twisted plastics threads and may be disposed on the same side of the backing web as the adhesive. They may be welded or glued to the backing web. In an example, a crimped paper web, coated on one side with pressure sensitive adhesive, is stretched before two parallel bundles of non-twisted plastics filaments are pressed into the adhesive coating. The web is then relieved of tension, whereupon the longitudinally extending bundles assume a crimped formation.

Thermionic amplifiers. - A low-frequency amplifier is operable directly from the electric supply mains and is provided with a volume control and a control for adjusting tone. The Figure shows a two-stage amplifier operating a moving- coil speaker the field coil of which is fed from the rectifier N while the heating current for the cathode F of the first valve is the space current of the output valves VI, V2 and the current through the field coil L. The volume control consists of a potential-dividing device E while the tone control may comprise a variable choke K<1> or a condenser H<1> in series with the input transformer or a variable condenser in parallel to the input transformer. A resistance P which may be a neon lamp prevents a charge from remaining in the condensers of the filter circuit when the set is switched off. As applied to a gramophone, means may be provided to cut off the current supply to the turntable motor when the amplifier is disconnected from the pick-up.

Title: Process for producing alloys containing alkaline earth metals
IPC: C22C1/02
Filed: 1920-05-19
Abstract: 164,608. Kroll, G. J. May 19, 1920. Alloys containing one or more alkaline earth metals are made bv the reaction of an alloy containing an alkali metal or metals and one or more halogen salts of the alkaline earth metal or metals, mixed or not with other salts, the materials being maintained in a highly fluid state during the reaction. The salts used may include double or multiple salts, mixtures of different alkaline earth salts, salts of other metals which are capable of replacing the alkali metal in the alkali metal alloy such as aluminium, cadmium, copper, zinc, lead and bismuth, or salts of metals inert to the alkali metal in the alloy, such as sodium. If the metal which is to be alloyed with the alkaline earth metal does not alloy with an alkali metal, mechanical mixtures of the metals and alkali metal may be used. The salts may be present in large excess of the theoretical amount, for example 2-5 times, and may be heated considerably above their melting point. In some cases the alkali metal alloy or the molten salt or both may be maintained in motion during the reaction for example by a counter-current method, or by causing the materials to impinge on each other, and the molten salt may be renewed during the process of substitution. The production of the following alloys is referred to : lead and calcium; lead and barium; lead, calcium, and barium; lead, calcium, and magnesium; lead, barium and magnesium; aluminium and magnesium; aluminium and beryllium: copper, calcium, and boron; lead, manganese, and barium; copper, aluminium, and calcium.

Abstract: 709,197. Cigarette-making machines. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. May 31, 1951 [June 2, 1950], No 13886/50. Class 130 The leading end of a forwardly-fed tobacco rod, as from a "make-up" conveyer 2, overhangs a faster-moving paper web 20 against which leading lengths periodically severed from the rod as by a narrowbladed rotary knife 7 are pressed as by a sector-shaped roller 17 immediately after severance so as to be carried along by the web and form spaces between successive lengths into which mouthpiece portions (or "stubs") such as cardboard tubes, or paper &c. plugs with or without absorbent material, are inserted to form a composite filler subsequently enclosed in the web to form a composite cigarette rod. As shown, stubs from a rotary fluted supply drum 15 are carried round on the concave rim of a wheel 9 under a guide 16 by pushers 12 pivoted on the wheel 9 and retracted by the action of a stationary cam 14 as the stubs enter the spaces, which are of a length substantially that of a stub, stub insertion being facilitated by rotating the wheel 9 at a peripheral speed 10 per cent to 20 per cent faster than the web speed so that each space is temporariy enlarged by endwise pressure of the inserted stub on one adjacent tobacco length to cause endwise contraction thereof. The wheel 9 bears on the tobacco lengths to assist in their acceleration by the roller 17 and is provided with. a scraper 18 which may bear on the composite filler. An intermittently operated blowing device 27 is timed to blow air across each successive space between the filler portions and clean the web 20, just before and during stub insertion, and a suction nozzle 28 positioned beneath the web 20 and its supporting conveyer 19, just before they pass under a wrapping tongue 21, acts to keep the exterior surface of the web clean. Rotarywheel accelerating fingers 22a, 22b as in Specification 709,203 are employed or, according to the Provisional Specification, linkage-operated accelerating fingers as in Specification 703,982. Specification 709,260 also is referred to.
