Title: Improvements in and relating to the measurement of alternating electric current power
IPC: G01R11/52
Filed: 1918-12-21
Abstract: 137,090. Ferranti, S. Z. de, Wall, G., and Ferranti, Ltd. Dec. 21, 1918. Induction motor meters; power meters; registering special quantities.-A power or energy meter of the induction type is adapted to measures the wattles component of the apparent power or energy by interchanging the series coil a and shunt coil c as regards the cores on which they are wound, the effect being to bring the shunt and series fluxes into phase on non-inductive load. Adjustment for no rotation with the pressure coils alone excited is effected by placing a copper stamping or closed wire loop on one of the outside limbs of the shunt magnet, or by a lateral displacement or a tilt of the series magnet. Adjustment for no rotation with the current coil alone excited is effected by adjusting the position of the series coil along its core, by reducing the area of part of the copper stamping round the poles of the series magnet, or by the adjustment of iron screws in rotation to the series magnet. The phases of the shunt and series fluxes are adjusted to identity by adjusting a resistance or inductance in the shunt circuit, or by adjusting a copper stamping longitudinally along the polepieces of the series magnet. The full-load speed is adjusted by moving the retarding permanent magnet towards or away from the spindle. Several driving-elements may act on a single rotor system for polyphase measurements, the connexions being analogous to those employed in energy meters as shown, for example, in Specification 21355/99.

Title: Improvements in or relating to the coating of materials
IPC: D06M15/05
Filed: 1934-07-23
Abstract: Sheet materials or articles are coated by <PICT:0441622/III/1> applying thereto a layer of a thermoplastic composition prepared by grinding a thermoplastic substance in the presence of a nonsolvent and removing the non-solvent, causing the layer to adhere to the surface by the application of heat and pressure, and supplying heat during the pressing operation to, and/or withdrawing heat immediately after the pressing operation from, the thermoplastic layer through the said surface.  The grinding may be effected in a colloid mill having abrasive discs, as described in Specification 428,456.  The thermoplastic composition may be prepared from a cellulose ester such as the nitrate, acetate, formate, propionate or butyrate, or an ether such as methyl, ethyl, or benzyl cellulose, or from rubber, halogenated (e.g. chlorinated) rubber, resins, e.g. vinyl resins such as polyvinyl acetate or polystyrol, or from two or more of these substances, with or without plasticizers, dyes, pigments, lakes, fillers, resins, oils, &c.  Suitable plasticizers are camphor, diethyl or dibutyl phthalate, triphenyl or tricresyl phosphate, and ethyl paratoluene sulphonamide.  The composition may be applied as a powder, or may be formed into a layer continuously with its application to the surface by passing the composition in the form of powder, grains, blocks, slabs, or strips between a series of heated rollers.  Cardboard, pulp, &c., sheets, blocks, strips, &c., of wood, cork, rubber, asbestos board, metals, glass, slate, &c., and rods, profile strips, tubes, mouldings, corset stays, lead pencils &c., may be coated.  As shown, a thermoplastic composition in a hopper 1 is formed by the action of heated rolls 2--5 driven at the same or different peripheral speeds, into a layer which is applied to rigid sheets, panels &c., of wood, asbestos, metal &c., as they pass over a heated roll 12 situated between heated and cooled tables 13 and 15, the surfaces of which are preferably level with the crown of the roller 12, the tables and roller 12 being adjustable in height relatively to the roller 5.  By supplying differently-coloured powders, blocks, ribbons, &c., of the thermoplastic composition to hopper 1, variegated or striped effects are obtained.  Embossed metallic or hard surfaces may be coated so as to fill only the depressions giving an inlay enamel effect.  Metal sheets &c., when coated may be stamped, drawn, rolled, milled, &c.  Two examples of plasticized cellulose acetate compositions are given.  The Specification as open to inspection under Sect. 91 describes coating materials or articles with thermoplastic compositions free from volatile solvents or liquids with the aid of heat and pressure.  This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to degreasing processes and apparatus
IPC: D06F43/08
Filed: 1954-07-23
Abstract: <PICT:0771492/III/1> <PICT:0771492/III/2> In a process wherein textiles are degreased with a solvent and subsequently dried, the dust being removed by air circulation, the degreasing is effected with a small amount of solvent sufficient only to dissolve the grease in the material being cleaned and thus unable to remove the dust, and most of the drying is carried out thermally, without solvent removal by centrifugation, the heat required for the drying being supplied by a heat supply distinct from the dust-withdrawing air.  In a suitable plant, the cleaning apparatus comprises a rotatable perforated drum 7 within a fixed container 2 to which the solvent is supplied, a reservoir 21 for the used solvent connected through a liquid control chamber 24 to the container 2, and a pump 27 for forcing the used solvent through a filter 30 for return to the container 2 through a pipe 64.  The perforated drum 7 is given an oscillating movement during the cleaning step and its contents may be rinsed by purified solvent from the filter 30.  The perforated drum 7 is provided with heating pipes or a coil 20 integral therewith and is supplied through its supporting shafts with steam for the drying step or with cold water in a final cooling step.  Steam is also supplied to the container 2 through inlets 5 and 6.  After the cleansing step, steam is admitted to the container and also to the heating pipes 20 on the drum 7, which latter is further oscillated.  A compressor 31 is then started to remove the solvent vapours and supply them to a condenser 33, from which purified air is then fed to the container 2 through a pipe 34 for removing dust from the dried materials being cleaned. The filter is of known type comprising two concentric vertical filtering membranes which may be vibrated.  The condenser 33 contains a baffle arrangement to impart a cyclone action to the vapour laden air.  The used solvent may be diverted to a still 50.
