Title: Improvements in or relating to Methods Of Fixing A Powder To A Support
IPC: H01J9/227
Filed: 1966-09-27
Abstract: 1,152,478. Photographic processes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 27, 1966 [Sept. 30, 1965], No.43117/66. Heading G2C. [Also in Division H1] A method of fixing a powder to a support comprises, taken in order, the steps of spreading a solution of a photo-sensitive binder on the support, drying the resulting layer and exposing selected areas of the layer to radiation so that selected areas of the layer are more soluble in a solvent than other areas, removing the soluble areas of the layer with the solvent, spreading over the support and binding layer a suspension of the powder which does not contain a macromolecular organic compound, adding to the spread suspension a solution of a macromolecular organic compound, e.g. polyvinylalcohol, drying the suspension and solution and rinsing away the powder from areas of the support no longer coated with binder. The radiation may harden the exposed areas of the binder to render them insoluble in the solvent. The method may be used to apply the guard bands to the recess of an indexing type colour television tube. A specific example with quantities is given in which black iron oxide is fixed to a colour index tube screen using a binder comprising polyvinylalcohol with an ammonium bichromate sensitizer, and a solution of polyvinylalcohol as the macromolecular organic compound.

Abstract: 1,212,518. Radio cartridge for tape recorder. AUTOMATIC RADIO MFG. CO. Inc. 25 Sept., 1967 [7 Dec., 1966], No. 43421/67. Heading H3Q. A radio cartridge for insertion into a tape recorder not containing an internal loud-speaker feeds its audio output into a coupling head which, when the cartridge is in position, is in close proximity to the tape-scanning head and induces signals therein. Fig. 3 shows the cartridge 11 in position, with the output head 13 coupled to the tape-scanning head 14. Power for the cartridge is supplied through terminals 21, 22 via a bridge rectifier 45 in case the polarity is wrong. A microswitch 54/55 may disable the tape motor when receiving radio programmes. The terminals 21, 22 are normally bridged by a conductive strip on the tape to shift the head 14 to scan the next track by means of a solenoid 34, but when the radio cartridge is in position the current is reduced by resistor 44 to prevent this happening. The solenoid coil then acts as a filter to decouple the radio circuits from the audio amplifier in the tape recorder. The aerial connection is normally via the tape recorder chassis (51-53 in Fig. 2, not shown), but a separate aerial socket (31<SP>1</SP>) may be provided on the tuner cartridge.

In an aerial mast comprising a plurality of similar sections interfitting end to end (only a section 2 and part of an adjoining section 3 being shown), each section is slidable upwardly through a guide structure 7 supported by a tripod 8 and incorporating pivoted locking cams, Fig. 2 (not shown), preventing downward movement. The mast may thus be erected by feeding successive sections from below through the structure 7, and the structure 7 and tripod 8 then form the base of the mast. Release catches are provided to retract the locking cams when desired. The topmost section may carry an aerial dish or array, and have attached guy cables stored in drums on the structure 7. As shown each section 2 comprises three tubes 4 spaced by triangular plates 5, successive sections interfitting through spikes 6.

Filed: 1972-09-20
Abstract: 1442987 Making headed fasteners; heading GKN BOLTS & NUTS Ltd 30 Oct 1973 [20 Sept 1972] 43534/72 Headings B3A and B3H A headed fastener, such as a bolt, rivet, set pin &c. is made from black bar stock steel by sizing the stock in a metal removing operation followed by a simple blow cold heading operation. The metal removing may be produced by turning or grinding. The black bar stock is initially straightened before being sized and blanks are cropped from the stock before or after sizing. The blank ends are turned and bevelled to produce a symmetrical end prior to heading. Before heading the blank is phosphated and lubricated. The heading tool 10 has a recess 11 which co-operates with a retaining ring 17 and a die 12 to shape the head. After heading the blank shank is extruded in a second die set with a stepped cylindrical die passage. The blank is ejected through the extrusion punch which trims the forged head. The blank shank is then thread rolled and heat treated if desired.

The microspheres have preferably the following dimensions, particle size 5-1000 Á, wall thickness 0À5 to 50 Á, and bulk density 0À05 to 0À4. The spheres may be used as a catalyst or in purifying contaminated water. Purifying water.-Purification is effected by flowing the water to be purified downwardly through a column whilst maintaining the active microspheres as a floating layer upon a body of supported water, removing spent spheres from the top of the column and introducing fresh active spheres at the bottom of the column. As shown in the Figure, waster water to be cleaned is introduced through inlet (A), and via spray device (C) supplied as droplets to floating layer (F) of active microspheres. The cleansed water leaves the column by pipe (K). Fresh microspheres are supplied to the bottom of the column by tube (H) and distributer (G). The deactivated microspheres are removed by skimmer (B) rotating in pit (D) and tube (E). The liquid level is adjusted by tube (I). The Specification also includes a flow diagram (not shown) of a continuous water purification process including regeneration of the deactivated microspheres utilizing treatment conditions similar to the conditions used in their initial formation.
