Title: Electric recording by deposition of dye, pigment, other colouring matter or the like
IPC: H04N1/034
Filed: 1945-09-12
Abstract: 606,130. Copying by scanning. WHITE, D. D., OSBORN, F. R., and REICH, S. Sept. 12, 1945, Nos. 23545/45 and 11721/46. [Class 40 (iii)] In an electric recording system particles of colouring-matter are both disintegrated into mist and projected on to. a receiving surface by the action of an electric field between the said surface and the colourdepositing device, the intensity of colour deposit being determined by the voltage (above the minimum required to disintegrate the particle) applied to the said electric field. In a system, such as described in Specification 606,133,. voltage, modulated by picture signals is applied between a pointed pen device and a metallic drum bearing a recording surface, and a drop of dye or the like at the point of the pen is thus electrically dispersed in a fine mist which is drawn toward the recording surface, the intensity of the colour deposit being determined by the modulating voltage. The pen 22 may comprise a tube 30 of fine bore ground to a point 31 and having an insulated fibre 32, terminated in a bead 33, passing through the bore. The control voltage may be applied to a wire dipping into the liquid colouring-matter in the tube, or to a metallic sleeve on the outside of the tube, or the tube itself may be of metal, with or without an insulating tip. The pen may be constructed with external capillary grooves (Figs. 3, 4, not shown) instead of a central bore. In a modification, the spray discharge may be focused on to the receiving surface by control electrodes. The pen may be 'surrounded by an electrically conducting sleeve, Fig. 5 (not shown), to stabilize or shape the electric field, and vapour saturated with the solvent in use may thereby be conducted over the colour solution to prevent evaporation. The receiving surface may be heated, to prevent the accumulation thereon of undesired electric charges, with a salt (e.g. lithium chloride) or a hygroscopic agent (e.g. glycerine). The conductivity of the colouring liquid may also be controlled. For colour reproduction three or more scanning beams, photo-cells, transmitting circuits and depositing pens are employed. Contrast, density or colour control and corrections for aberrations of the colour depositing device may be effected by injecting suitable voltages into the signal amplifier.

Title: Preparation of zeolites
IPC: B01J29/08
Filed: 1962-06-19
Abstract: Zeolites having the approximate formula Na2O.Al2O3.3-5SiO2nH2O (where n is small number) are prepared by adding finely divided silica to a solution of sodium hydroxide and alumina, the components being present in proportions by weight of 36-144 water, 6-24 silica, and 3-12 fats of sodium oxide per part of alumina, ageing the mixture and then heating to crystallize the synthetic zeolite. The ammonium form of the zeolite is prepared by treating a zeolite of the above formula with ammonium chloride solution preferably about 10% solution, and this is converted to the hydrogen form by heating to drive off ammonia. Ageing takes place at 20-60 DEG  C. for at least 3 hours and crystallization is effected at 50-120 DEG  C. for 3-72 hours, the product is filtered and worked with de-ionized water.  In examples sodium hydroxide solution and alumina trihydrate are mixed, and fine silica added and mixed, ageing and crystallization being then carried out and followed by optional ammonium exchange.

Abstract: 640,851. Stencilling-apparatus; feeding webs. WHITE, CHILD, & BENEY GES. Sept. 10, 1948, No. 23817. Convention date, Jan. 12, 1942. [Classes 100 (i) and 100 (ii)] Webs to be printed by stencilling are fed from a roll 7 over a printing table 1 provided with registering marks by means of a conveyer band 2 which is coated with adhesive before engaging the underside of the web to be printed. The web is led from a drum 7 over guide rolls 9, 10, 11 and wound up into a roll 8. The conveyer band 2 is tensioned by a pulley 16, and is driven by a motor 17 and an electric coupling 21 which throws in and out a chain drive 18, 19, 20 for advancing the web. This drive acts through a free-wheel drive to operate the shaft 20 of the conveyer 2, and the conveyer operates a counting-apparatus which is set to disconnect the coupling 21 and apply a brake to stop the conveyer just before the web reaches, the registering mark. The web is then given a fine adjustment by means of a hand crank 30 which is geared to the shaft 20 by means of a freewheel drive. The band 2 is kept clean by means such as brush rollers 15. In case of a breakdown in the power feed the hand feed can be used to effect the feed until the power-feed is restored.
