Filed: 1931-06-04
Abstract: 379,734. L a b e l l i n g - m a c h i n e s . BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester.-(Assignees of Edwards, H. E. ; Brookline, Massachusetts, U.S.A.) June 4, 1931, No. 16201. Convention date, June 9, 1930. [Class 73.] A machine for affixing adhesive labels, more particularly to sock linings for shoes, comprises means for severing the label from a strip and applying it by pressure and heat, means being provided for supporting the projecting end of the strip to prevent rucking until it is severed and applied,'and for separating a backing strip from the label strip ; means for freeing the severed end from the shears are also provided, and a printing device may also be actuated from the pressing device to print on the strip. Figs. 1 and 2 show views at right angles. The strip is led from a reel 18 between an endless band 26 and roller 27, the band being mounted on rollers 33, 36 and the roller 27 carried on a pivoted stirrup 28. The backing strip is removed by an edge 112 on-the work support 24 and passes to waste. The roller 33 is driven by a pawl 86 operated by a link 89 connected to a lever 90 which is operated by a telescopic spring link 95 and works between adjustable stops 101, 102. The end of the strip passes a slot 40 in a plate 39 and lies on a rest 41, which slides along the work support 24 and is operated by a spring-returned lever 51 the upper end 60 of which is engaged by a projection 59 on a spring-influenced arm 58 ; the latter is provided with an inclined surface 61 engaging a stop 53 whereby on the depression of the arm 58 it is swung about its pivot after the projection has effected the operation of the lever 51 to allow the return of the latter. The label is severed from the strip and affixed by a presser 67 operated from the pedal 45, the edge 69 of the presser co-operating with an inclined shearing edge 77 on the slot 40 ; the severed edge is freed from the shearing edge by a spring-influenced lever 108 operated by the depression of the presser. The presser is electrically heated, and the plate 38 slightly inclined to maintain uniform shearing relation between the plate and presser notwithstanding expansion of the presser by heat. When the label is printed in the machine, an attachment is provided comprising a printing head which is reciprocated between an upper inking pad and a lower printing bed over which the strip is led before it passes to the severing and attaching devices. Specification 1068/12, [Class 73, Labels &c.], is referred to.

Abstract: 1450076 Controlling aircraft power plant ROLLS-ROYCE (1971) Ltd 29 March 1974 [5 April 1973] 16259/73 Heading B7G A control system for a gas turbine engine 30 which is provided with thrust reversing means 34 comprises power selector means 1 adapted to control engine power and thrust control means 2 adapted to adjust the thrust reversing means 34, the control means 2 also being adapted to vary the power from the engine whilst adjusting the thrust reversing means irrespective of the degree of power selected by the selector means 1. The engine has a shut-off control actuated by linkwork 68, 69 and a fuel control unit actuated by a lever 60 and chain and sprocket drive 61-63. The thrust reverser is actuated by an air-motor 94 supplied with air from the engine compressor through a one-way valve 92 and a spool 73 which is controlled by linkwork 47 and lever 74 mounted on a pivot 75 carried by a screw 76 to provide feedback. The power selector 1 which is released by depression of a handle to free rachet device 85, 86 is movable between position 16 (maximum power for take-off), position 17 (maximum continuous power), position 18 (flight idle), position 19 (engine start) and position 20 (engine shut-off). The selector incorporates two cam slots 52 and 64 within which are respectively positioned rollers 51 and 65, roller 51 being connected by link 59 to the fuel control drive and roller 65 being mounted on a lever 66 pivoted at 67 and connected to the shut-off control drive. The thrust control means 2 is movable between position 10, where it selects take-off power irrespective of the position of selector 1, position 11 which reduces the power of the engine to the level set by selector 1, between positions 11 to 13 to cause the thrust reverser to deploy at the power selected by power selector 1, between positions 13 to 14 to cause full deployment of the thrust reverser together with a progressive increase in power over that selected by selector 1. Final movement to position 15 continues to increase engine power to a maximum with the reverser in full reversethrust position. A stop 4, provided by a lever 77 recessed at 78 to receive a plunger 79, is mounted to hold the control at position 11 and is released by upward movement of a rod 80 operated during aircraft descent, e.g. by landing flap mechanism. A further stop 5 provided by a lever 81 holds the control at a position 12 corresponding to aircraft descent and this is released, e.g. by aircraft undercarriage compression. The operative connection between the power and thrust controls is provided by cam tracks 41 and 42 in control 2 engaged respectively by rollers 44 and 57, the former being mounted on one end of a pivoted lever 45 which is connected to linkwork 47 and the latter being mounted on a pivoted lever 55 which is connected by link 54 to roller 51.

Filed: 1944-08-31
Abstract: 582,290. Harpoons. TROUTON, R. DE B., and BJOERNSGAARD, P. Aug. 31, 1944, No. 16617. [Class 9 (i)] Relates to explosive heads of whaling harpoons, and consists in making the casing of the explosive charge of a mouldable non- metallic substance, sufficiently rigid when cold or dry to ensure penetration into the body of the whale, but the.fragments of which are capable of being softened by the heat or moisture of the whale's body. The object of the invention is to avoid damage to the knives used in cutting up the body of the whale through fragments of metal that would be left in the body if a metal casing were disrupted inside it. In the construction shown, the shaft 1, slotted for attachment of a line, is linked to a part 5, to which the casing 8 is screwed. The casing is made of compressed paper strips treated with glue or the like. Vanes 9, which are pre ferably non-metallic, are provided to prevent the harpoon from rotating during flight, and may be moulded integrally with the casing or screwed into grooves therein. The usual means are provided for detonating the explosive charge. As shown, these may comprise a fuze cord 16 which leads to a detonator charge 12 and is ignited by a cap 20, mounted on a hammer 18, when the harpoon is fired. Barbs 6 are also provided to embed themselves in the whale's body in known manner. The explosive head may be strengthened by a central steel rod which, being so placed, is not likely to be broken up by the explosion.
