[Also in Division B6] A sheet to be electrostatically charged, or superimposed sheets between which a developed image is to be transferred, is or are placed between a dielectric covered first conductor and a second conductor, a field is applied between the conductors, and undesired charge is removed from the dielectric. As shown in Fig. 2 a battery 8 applies a field between rollers 5 and 6 to charge a sheet 7 and a battery 10 is connected to a roller 9 to remove charge from dielectric 5b. Similar systems are described with reference to Figs. 4, 7, 9 (not shown). As shown in Fig. 5, an A. C. source 17 is connected between rollers 5 and 6 to apply a field in one direction when a sheet is present and to apply a field in the opposite direction when a sheet is absent to remove charge from the dielectric 56. Similar systems are described with reference to Figs. 8, 10, 11 (not shown). Instead of using an A, C, source, rollers 5, 6 may be switched between two D.C. sources. Instead of roller electrodes, an endless dielectric band around two conductors Fig. 7 (not shown) or a pair of plates one of which reciprocates Fig. 8 (not shown) may be used.

Abstract: 1493661 Flocked yarns and webs made therefrom SCOTT PAPER CO 7 April 1975 [21 May 1974] 14212/75 Headings D1R and D1W A filamentary element comprises a corestrand of at least one polymeric filament having an adhesive layer, and substantially individualised cellulosic fibres adhered at any point along their length to the adhesive, the core-strand having a denier no greater than 40, the fibres having a length less than 6.35 mm and no less than 1 mm and constituting over 50 per cent by weight of the total element. By substantially individualised is meant that at least 51% of the fibres are adhered as individual fibres. The adhesive weight may be 30 to 300 per cent the weight of the core strand. The core-strand may have a denier of from 7 to 14 and each core-strand filament having a denier greater than 1.5. The core-strand filaments may be of nylon, polyester or polypropylene. The adhesive may be reactivatable; e.g. by heat, being made of vinyl acetate homopolymers and copolymers. polyethylene, polypropylene. polyamides, acrylics and cellulose acetate, or non-reactivatable; e.g. of urethane, polybutadiene, acrylic copolymers, vinyl acetate copolymers, and other cross-linked polymers. The cellulosic fibres may be of wood pulp or cotton linters. The element may comprise, Fig. 2 two core filaments 14 bonded together by adhesive 16 which also secures fibres 18. The yarn 30, Fig. 10, comprises elements bonded together by adhesive 16.

Title: Improvements in viscose process and products
IPC: D01F2/10
Filed: 1954-05-17
Abstract: Artificial thread is produced by the viscose process from wood pulp containing residual resins of the wood and an added water-soluble block copolymer of polyethylene oxide and polypropylene oxide having a central polypropylene oxide chain, preferably containing 26-31 propenoxy units, substituted at both ends by polyethylene oxide chains, each polyethylene oxide chain preferably having 6-106 ethenoxy units, in such proportion, e.g. 0.02-0.2 per cent, as to prevent the formation of resin agglomerates in the filaments and improve the fatigue properties of the thread.  In an example, a cellulose pulp containing 0.15 per cent of natural resin is treated with 0.1 per cent of a block copolymer having a central polypropylene oxide chain containing an average of about 28 propenoxy units substituted at both ends by polyethylene oxide chains each having an average of about 16 ethenoxy units, and the treated pulp is processed into a viscose from which is produced a tyre cord of 3650 total denier having a fatigue life of 187 (as determined by a described test) compared with a fatigue life of 5 for a tyre cord prepared from the same pulp to which no block copolymer has been added. Specification 735,481 is referred to.

Abstract: 234,853. Basset, L. P. June 2, 1924, [Convention date]. Alloys; dry processes of extracting metals.-In a process for the manufacture of metals and alloys in a rotary furnace, the ore, mixed with coal and fluxes if desired, is fed into the furnace and heated by the injection of coal in a divided state with air, the degree of fineness of the fuel and the proportion of air being so determined that two zones of combustion are produced in the furnace, the first of fusing zone, where the coal burns to form carbon dioxide, and the second or reducing zone, where the carbon dioxide produced in the first zone is converted into carbon monoxide by the excess of fuel not burned in the first zone, the coal being crushed finely, e.g. so that 98-99 per cent passes through a sieve having 4,900 meshes per sq. cm. but not through a smaller sieve. In operation, the ore &c. moves first into the second zone, where it is reduced, and the metal passes into the first zone where it is melted and protected from oxidation by the slag floating on it.

Title: Improvements in apparatus for observing smoke from boiler or other furnaces
IPC: G01J3/00
Filed: 1930-05-10
Abstract: <PICT:0354384/III/1> <PICT:0354384/III/2> <PICT:0354384/III/3> A beam of light is projected across the path of the gases leaving a furnace and is then analysed into its spectrum, changes in the spectrum indicating the presence and density of smoke.  Light from a lamp so passes across the flue or chimney d into a pipe p<1> and is deflected by a prism rp on to an analysing prism ap placed so that the spectrum can be seen by the furnace operator.  Emission of smoke causes first the yellow and then the blue to be cut out, and the fire is adjusted accordingly.  The curved front glass or lens projects into a clearance hole in the flue wall so that it is kept clean by air leakage into the flue. To stop considerable leakage of air into the flue through the pipe p<1> a removable transparent glass sheet s, Fig. 4, is interposed, space being left to allow a small leakage of air for cleaning the glass.  The deflecting prism rp is carried by a plate pl fixed to a ring r adjustable on the pipe p<1> and retained in adjusted position by a set pin sc.  The prism is adjusted regularly by a wing nut wn<1>.  The analysing prism ap is similarly adjusted and is provided with a sheet metal hood.  By using a compound prism the light may be viewed in a direct line with the lamp.  A transformer t supplies the lamp which is of the low-voltage type with a concentrated filament.  When using a lamp having an extended filament a piece of fine screening glass is cemented or clamped on the inner face of the front glass or lens. According to the Provisional Specification the light may fall upon a mirror or a screen of frosted glass.

Abstract: 213,805. Walther, G. June 1, 1923. Firing-appliances; safety appliances.-Firing mechanism for an automatic pistol has (a) a toggle link b interposed between the hammer 5 and the mainspring 10, the link b being movable to one side of the dead centre to lock the hammer in the safe position and to the other side to place the hammer under spring pressure for firing, (b) means actuated by gripping the handle to cause initial movement of the toggle link from the safe position towards or past the dead centre, and (c) trigger mechanism adapted either to actuate a sear to release the hammer, or to impart further movement to the toggle link past the dead centre. As shown in Fig. 1, the hammer 5 is moved backwards, and the toggle link b forwards, when the grip on the piston is released, by a spring-actuated lever 13 carrying a hooked link 20 engaging the hammer. When the pistol is gripped, the hammer is turned by the lever 13 until the toggle link b is at the dead centre and the hammer is still heM by the hooked link 20 which forms a sear. When the trigger is pulled, the trigger link 7 releases the sear 20, and also by means of a shoulder 8 imparts further movement to the hammer to move it past the dead centre. In a modification, Fig. 3, the mainspring 10 is mounted in a spring- pressed lever 15 pivoted at the back of the handle, and when the lever 15 is rearwards, as shown in Fig. 3, the toggle link b acts in front of the hammer pivot 1. When the pistol is gripped, the toggle link is moved to the dead centre, and, when the trigger is pulled, movememt past the dead centre is caused by the trigger link 7.
