Title: A method of applying variegated or "jazz" colourings to the surfaces of articles
IPC: B05D1/20
Filed: 1930-09-11
Abstract: Variegated colouring is applied to the surface of an article such as a rubber or other ball by bringing it into contact with or passing it through the surface of a liquid to which has been applied one or more liquid colouring-materials, the liquid being immiscible with the colouring-material and acting to split up the colouring-material into a number of parts and cause the parts to be dispersed, as distinct from a spreading-action wherein the material remains as a continuous film.  The colouring-materials may consist of pigments or dyes in rubber solution, oils, varnishes, cellulose, spirit, or the like, and the liquid may be water rendered alkaline as by the addition of a small amount of washing-soda.  The ornamentation of a ball may be improved by turning it horizontally to and fro as it is passed through the surface of the liquid.  After colouring, the balls are preferably varnished.

Title: Improvements relating to propeller drive mechanisms
IPC: B64D35/00
Filed: 1950-11-08
Abstract: 685,340. Gas turbine plant. GENERAL MOTORS CORPORATION. Nov. 8, 1950 [Nov. 19, 1949], No. 27249/50. Class 110(iii) [Also in Groups XXXIII and XXXIV] A pair of contra-rotating aircraft propellers 48, 56 are driven by gas turbines 10, 12 through shafts 22, 28, clutches 24, 30 and pinions 26, 32 meshing with a common pinion 34 coupled to the propellers by sun and planet gearing 38, 40 ... a propeller brake 64 being geared to the pinion 34 and so arranged as to be inoperative when the propellers are engine-driven, and operative when non powerdriven a " self-energising " action being obtained when the propellers rotate in reverse direction under such conditions to prevent windmilling due to over-feathering, but not when rotating in the forward direction. The brake is of the cone type and comprises two friction elements 84, 86, of which the former is driven by a pinion 68 meshing with the gear pinion 34, the pinion 68 being integral with a sleeve 74, 107, of which the portion 107 forms a cylinder for a piston 112. When the propellers are power-driven a gear-wheel pump 132, driven by the engine, supplies pressure liquid to the face of the piston 112 to overcome a compression spring 110 and thus disengage the brake friction elements, 84, 86. In the event of momentary oil failure at high engine speed the centrifugal head generated by the liquid rotating in the cylinder sets up sufficient pressure to maintain the brake elements disengaged until the speed falls sufficiently to allow safe brake application. If the propellers rotate in the forward direction when non power-driven the brake element 84 forces its co-operating element 86 into engagement with the fixed housing 37, but if in the reverse direction the members 84, 86 are drawn together by the action of a screw thread 90, by which the element 86 is mounted on a fixed sleeve 78, to give the self-energising action. Upon subsequent rotation in the normal direction the element 86 is moved back to its normal position against the housing 37, being assisted by a return spring 94. The brake elements 84, 86 are cooled, when engaged, by oil from the pump 132 which is delivered to the interior of a hollow sleeve 98 integral with the piston 112, from which it passes to the brake through aligned radial openings 75, 99 in sleeves 74, 98, respectively; when the brake elements are disengaged the openings 75, 99 move out of alignment and the oil supply is cut off.

Abstract: 1,198,179. Feeding tobacco. B. A. T. CIGARETTEN-FABRIKEN G.m.b.H. 11 June, 1968 [24 June, 1967], No. 27769/68. Heading A2C. A method of forming a strand of tobacco, from tobacco cut in the form of fibres which is fed continuously from a tobacco distributer, comprises forming a dense first strand having the fibres placed substantially mutually parallel, but transversely to the direction of travel of the strand whilst said strand is moved continuously forward, and continuously removing tobacco fibres from the front end of said strand while retaining their alignment, and transporting said fibres onward in close succession as a second strand in a direction parallel to the said alignment. Tobacco showered from a distributer (12) on to a conveyer belt (14) is fed into a suction hopper (16) leading to a channel 20. The channel 20 is bounded at its sides by two air permeable conveyer bands (26, 27) backed by suction applied perpendicularly to the bands (26, 27) which cause the tobacco to be compacted in the channel 20 with its fibres lying transverse to the direction of travel. The compaction point, as detected by light barrier elements 40, 42, is held within that part of the channel lying between said elements by control of the distributer (12) feed. The compacted tobacco stream is then stripped from the end of the channel 20 by a spiked wheel 56 and passes into a channel 60, while the fibres maintain their alignment. The fibres are then delivered to the channel 90, which is set at right angles to the channel 20, to form a second tobacco strand with its fibres parallel to its direction of movement. A vacuum chamber 68 underlies an air permeable conveyer belt 62 in the first half of the channel 90 and a vacuum chamber 78 overlies a similar conveyer belt 72 in the second half of the channel 90. The second tobacco strand, on leaving the channel 90 is deposited on a continuous paper band P and wrapped in conventional manner.
