Title: Improvements in or relating to water treatment
Inventor: DAVISON GEORGE TRAVIS
IPC: B01J49/00
Filed: 1952-12-19
Abstract: Ammonium ions are substantially completely removed from water by passing it through a bed of synthetic cation exchange resin capable of being regenerated by either an acid or alkali, until the effluent shows traces of ammonia, whereupon the flow is interrupted and the bed regenerated by passing therethrough an aqueous solution of an alkali metal hydroxide or carbonate; the cycle being then recommenced.  In the event of the water containing removable cations which would form an insoluble hydroxide or carbonate, such cations e.g., calcium ions are first removed from the resin by treatment with sodium chloride.  A suitable resin comprises a supplemented cross-linked polystyrene or an alkali metal salt thereof and the end point of the ammonia ion exchange process is determined by the use of Messler's reagent.  When operating the hydrogen cycle regeneration of the resin is effected by treating with sodium chloride solution to remove calcium ions if present, rinsing, treating with sodium hydroxide to remove ammonium ions, further rinsing and finally treating with hydrochloric acid solution to replace by hydrogen ions the sodium ions in the resin which displaced the calcium and ammonium ions.

Abstract: 1427649 Colour television tube PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 July 1974 [26 July 1973] 32539/74 Heading H1D In a three-gun colour TV tube (Fig. 1, not shown) with apertured shadow mask and luminescent screen 7, the three phosphor dots 24, 25, 26 luminescing red, green, blue respectively when bombarded by electrons from the respective guns are made smaller than their electron impact zones 27, 28, 29 (negative tolerance). The whole of the screen is coated with a thin reflective electron-permeable Al film 30, initially vapour-deposited over an acrylate skin which is later removed by heat. Ambient light will then be reflected specularly through face plate 2 by the inter-dot areas, reducing the loss of contrast. The film also increases the forward emission of light from the edges of the dots. If the phosphor areas are elongated strips, negative tolerance is ensured by making the phosphor strips narrower than their electron impact zones.

Title: Improvements in or relating to stencilling
IPC: B41C1/14
Filed: 1927-12-02
Abstract: 306,217. Owens, E. A. Dec. 2, 1927. Stencils and stencilling.-A stencil for use in multi-colour work is made by blocking out parts of a screen consisting of bolting cloth 1 stretched over a frame 2, Fig. 2, forcing an ink-resist through the permeable parts on to a transfer sheet, and using this sheet to apply the resist to a second screen 12, Fig. 11, which is used for stencilling. The screen 1 is cleaned after one or more transfer sheets have been made, and is then blocked out for the next part of the design- The design given as an example is a white disc C, Fig. 1, in the centre of a blue square B inside a red disc A. The outlines are traced on the fabric 1, the part 5 outside the circle A is blocked out with a permanent filler, such as cellulose lacquer or a varnish, and the remaining part, except the circle C, is blocked out with a temporary filler, such as water-soluble gum or glue. A resist such as shellac varnish is applied through the screen on to the transfer sheet, which has previously been sized, this sheet is laid on a plate E, Fig. 11, registered against gauges 14 - - 16 on a bed D below a hinged stencil-carrying frame 11, and pressure is applied. The transfer paper is stripped off, and red colour is applied through the stencil on to cards laid on the bed D against the gauges 14 - - 16. The gum is now washed off the screen 1, gum is applied to the part A, and a transfer sheet is made and used to block out another part of the stencil through which blue colour is then applied. Registration crosses 3, 4 may be marked on the screen 1 and resist applied and used to position the successive transfer sheets on the support E; also, a number of designs may be printed at one operation by making a number of transfer sheets each time and arranging them on the support E.

Void [Abridged as open to inspection under Sect. 91 of the Acts, July 27, 1934]. [Class 39 (i)] [See also Group XI] Cathode rays are used to generate heat by bombarding an anticathode directly or after a series of reflection. Heat from the atomic disintegration of the electrodes is referred to. Electrodes 2, 3, Fig. 1, and an anticathode 4 are arranged so that electrons are reflected between the plate electrodes 3 and 4. Heat from the anticathode 4 is conducted to the outside of the tube 1 by a bar 5 leading to a radiator 6 or by circulating fluid such as air or water through a reservoir adjacent the anticathode or through a spiral pipe forming the anticathode. The anticathode may be at earth or varying potential. The electrodes 2, 4 may be of alloys of " low atomic density." In a modification, the anticathode is outside the tube and the rays pass through a metal end-wall of the tube. In another modification, Fig. 6, the anticathode 4 forms an end wall of the tube and electrons from a hot filament 12 are repelled towards the anticathode by a negatively biassed electrode 17 which may be parabolic with its focus at the filament 12. The rays may be concentrated by adjustable focussing devices. In a further modification, the metal vacuum vessel forms the anticathode and surrounds, and is connected to the positive end of, a heated filament. The filament leads pass through a plug which can be unscrewed when the filament is to be renewed.

Title: Rotor assembly
IPC: B04B9/12
Filed: 1975-08-05
Abstract: 1478577 Driving spinning rotors MASCHINENFABRIK AUGSBURG NURNBERG 5 Aug 1975 [5 Aug 1974] 32652/75 Heading DID [Also in Division F2] A thread spinning rotor drum 1 having a frusto-conical peripheral surface is magnetically supported and driven by a magnetic coil assembly 3 which has a correspondingly shaped inner surface and which is arranged so that in operation the rotor drum is magnetically suspended at least partly within the coil assembly with its peripheral surface 2 defining an air gap of substantially uniform width with the inner surface of the coil assembly. This inner surface is provided with a coating 4 of antifriction material, e.g. P.T.F.E. A receptacle 5, the interior of which is coated with P.T.F.E., is mounted beneath the rotor drum 1 so as to swivel about an axle 6. If the rotor drum requires cleaning, the driving rotary field current in the magnetic coil assembly is switched off or reversed so as to brake the drum. When the latter has been slowed down to a predetermined speed, the supporting field current in the coil assembly is switched off and the rotor drum 1 drops into the interior of the receptacle where it comes to rest on the P.T.F.E. coating. The receptacle is swung out, the drum is taken out for cleaning at a washing plant and is replaced by a fresh drum and the receptacle is swung back into position, whereupon the supporting field current is switched on to bring the rotor drum up into its operating position within the coil assembly. Finally, the driving field current is switched on to rotate the rotor drum. Sensing means may be associated with a control device and with the magnetic coil assembly for detecting the position of the rotor drum relative to the coil assembly and, in the event of positional errors. The control device causes the magnetic coils to exert their adjusting effect to correct the position of the rotor drum. At least part of the periphery of the rotor drum may constitute a permanent magnet and a stationary magnetic field may be set up in the magnetic coil assembly. This stationary field may be generated either by the magnetic coils alone or, additionally, from a permanent annular magnet.
