Title: Method of and means for preventing the accumulation of ice on aircraft
IPC: B64D15/16
Filed: 1934-04-03
Abstract: 439,284. Preventing accumulation of ice on aircraft. BARKER, G. G., 14, High Holborn, London.-(Bendix Aviation Corporation ; 105, West Adams Street, Chicago, U.S.A.) April 3, 1934, No. 10016. [Class 4] Means for preventing accumulation of ice on aircraft surfaces comprise flexible members adapted to be intermittently expanded and contracted in which the exhaust of one member is used for inflating another member. As shown, the flexible members are mounted on the leading edges of the wings and tail plane and are expanded by compressed air from an engine driven pump 23 through outlets 34, 36, 37 in a distributer 26. The distributer includes a rotor 46 driven through reduction gearing 62, 63, 64, shaped as shown at 47, 58 and provided with an axial bore 46 communicating with the pump through openings 79, housing 27 and ports 31. With the rotor in the position shown in Fig. 8, air is being supplied to outlet 34, anticlockwise rotation of the rotor to the position shown in Fig. 9 allows air to pass from outlet 34 to outlet 36 and further rotation supplies outlet 36 only. This action is repeated successively during rotation. Air is exhausted into the atmosphere through outlet ports 57 past the portion 58 of the rotor which is divided longitudinally by cork washers 53, 56, 59. The outer end of the distributer casing is closed by a plug 52 which may be connected to a discharge valve to render the apparatus inoperative, or may be controlled to maintain constant the fluid pressure. The members 13 may be built up of a number of compartments.

Title: Improvements in or relating to the manufacture of soap
IPC: C11D13/04
Filed: 1940-06-08
Abstract: 549,386. Manufacture of soap. SHARPLES CORPORATION. June 8, 1940, No. 10058. Convention date, May 10, 1940. [Class 91] Soap is manufactured by a continuous process which comprises passing fat and a saponifying agent through a mixer, where saponification takes place, to a centrifuge to separate the soap from the aqueous phase, characterized in that a mineral salt is added to the initial material and is present throughout the saponification. It is stated that the retarding effect of the salt on the saponification is offset by the intense agitation in the mixer, and the presence of the soap causes an emulsion to be formed which promotes intimate contact between the fat and the saponifying agent. In addition the water and brine effect a continuous washing of the soap curds and so eliminate the necessity for subsequent washing operations. Other metal salting out agents may be substituted for brine. A mutual solvent for the lye and fat such as ethyl alcohol may be added at the mixing stage. An embodiment of the invention is shown in the Figure in which a two-stage process is used. A mixture of tallow and cocoanut oil is passed from container 10 by pump 11 through mixer 12 together with lye and brine from tank 13 under substantial superatmospheric pressure through a mixer 12, where saponification takes place, to a centrifuge 16. The amount of lye which is used should be slightly less than the stoichiometric equivalent of the fat passed to the mixer. An aqueous solution of lye and brine is fed by pump 18 into the soap-receiving cover of the centrifuge 16 to wash the soap from the cover, and to supply the saponifying agent for the second stage. The soap is passed from the centrifuge 16 to a second saponification stage to effect the complete saponification of any fat not decomposed in the first stage, which takes place in the mixer 19, The product from this stage is separated in the centrifuge 20, and the soap obtained thereby washed wtih brine. The brine which is so used is recovered from the centrifuge 24 and passed back to be re-used in the lye-brine tank 1. The soap is finally washed with water and passed from centrifuge 31 as neat soap. Specifications 410,959, [Group XXVI], and 549,387 are referred to.

Title: A process and device for the production of froth on beer after or during its being poured out
IPC: B67D1/14
Filed: 1930-03-29
Abstract: A lasting froth is obtained on beer by supplying a froth forming gaseous medium to the beer in amounts exceeding those which can be dissolved by the beer at the pressure prevailing during the supply of the gas, the gas being disintegrated into finely-dispersed tiny bubbles which are admixed with the mass of beer.  Rapidly moved agitation or whipping members are employed for dispersing the gas, which may be air or carbon dioxide, or the gas may be passed through a porous member.  Part of the beer only may be treated in this manner and poured on to untreated beer. The supply of gas may be combined with the dispersing apparatus, the first turning of a cock causing the beer to flow and a further turning of the cock causing the beer to pass to the froth-forming device.

Title: Cigarette making machine
IPC: A24C5/18
Filed: 1962-03-16
Abstract: 974,092. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. March 16, 1962 [March 16, 1961], No. 10175/62. Heading A2C. A method of making a cigarette rod includes the steps of forming a tobacco stream, removing tobacco from the top of the stream so that the remaining stream has a desired cross-section, redistributing the removed tobacco and adding it to the opposite side of the stream at a location before it reaches the location of tobacco removal so that thereafter the modified stream has an excessive cross-section, and forming the remaining stream into a cigarette rod. Tobacco is showered from a duct 10 on to an endless belt 13 from which it is removed by a suction drum 14. The top of the tobacco stream leaving the drum 16 is trimmed by a knife 20 and the excess tobacco conveyed, as by a shoot 18, to a pin wheel 23. The wheel 23 is driven by a motor 25 and co-operates with a picker wheel 29 to break up lumps in the excess tobacco and to redistribute the tobacco on the opposite side of the main stream on the belt 13 to form a stream of excessive cross-section. The trimmed tobacco is removed from the drum 14 by a stripper 30 and fed to cigarette rod forming apparatus. In a second embodiment (Fig. 2, not shown) the thickness of the stream leaving the duct 10 is electrically detected, the signals being used to control the motor 25 so that the correct amount of additional tobacco is fed on to the main stream of tobacco by the wheels 23 and 29.

Title: Improvements relating to laminated electric insulating paper products
IPC: H01B7/02
Filed: 1962-03-16
Abstract: The method of the parent Specification is modified in that the crepe paper is applied in such a manner that the individual layers are free to move relatively to one another in the circumferential direction and to adapt themselves to any subsequent changes in circumferential length such as may occur when the synthetic resin hardens.  This may be achieved by separating consecutive layers of crepe paper by an inter layer of a smooth, foil-like material, which may be perforated and may be electrically conducting, or be provided with a conducting layer.  Examples of separating layers are aluminium foil, paper-backed aluminium foil, fine-gauge wire mesh, graphitized paper, metallized papers and foils, smooth paper, fabric of natural or artificial fibres, unwoven fabrics or foils.  Alternatively, consecutive layers of crepe paper are so applied that the direction of creping in one layer is at an angle to that in the next, e.g. by winding tapes helically without overlap and winding adjacent layers of opposite hand.  At least some of the layers may be constituted by closed tubular structures, which may be drawn on in a prestressed condition. The liquid synthetic resin used may be provided with fillers, e.g. quartz meal.

Title: Improved manufacture of heat cast refractories
IPC: C04B35/484
Filed: 1943-06-30
Abstract: A heat-cast basic refractory, which is not brittle, porous, or cracked, has, as two of its major crystalline constituents, zirconia and forsterite in a non-crystalline matrix, the forsterite composing at least 20.7 per cent of the mix and the zirconia being included with the basic phases of forsterite and magnesium spinel with which periclase may or may not be associated.  The refractories are melted electrically and cast in preformed moulds.  Zirkite, zircon, magnesite, talc, bauxite, kyanite and olivine may be used as raw materials, but the content of ferrous oxide should be low to avoid porosity.  To ensure non-porosity, silica must be present in an amount at least equal to 11 per cent, and in a forsterite-zirconia system, containing only small amounts of spinel, there may be only 15 per cent zirconia present.  Larger amounts of spinel can be present, provided that the amounts of zirconia and silica exceed 15 per cent and 11 per cent respectively, whereby a gradation in basicity can be obtained.  The aluminium can be added in the form of a siliceous ore to provide the silica necessary for the formation of the forsterite. Further magnesia can be included if at least 15 per cent of both spinel and zirconia are present, the excess magnesia over that required to constitute the forsterite forming a solid solution in the zirconia.
