Abstract: 361,118. Photo-electric cells. GRAMOPHONE CO., Ltd., Hayes, Middlesex, TEDHAM, W. F., 267, Woolwich Road, Abbey Road, London, and BAKER, G. B., 16, Crick Road, Oxford. Nov. 21, 1930, No. 35181. Drawings to Specification. [Class 39 (i).] The surface of a silver or other support is oxidized before deposition thereon of an alkali metal, by passing a continuous wave high-frequency discharge between an electrode and the support in oxygen at low pressure. The voltage of the discharge is 350-1500 volts. For an area of silver surface of 80 sq. cms., a pressure of oxygen of 0À06 mm. at 20‹ C. is absorbed from a volume of 1000 c.cs. The envelope is evacuated and baked at 500‹ C. for 30 minutes and then at 350‹ C. for 10 minutes. A tungsten spiral is heated so as to vaporize a silver bead and deposit silver on the envelope. Oxygen is admitted at 0À20 mm., and a glow discharge at 1000 kilocycles is passed between a disc and spiral as one electrode and the silver coating as the other, using a valve oscillator as generator. After a discharge of 30 seconds the layer of oxide is of a deep gold colour. Excess oxygen is evacuated and caesium admitted by distillation from a side tube containing a mixture of calcium turnings and caesium bromide powder: or the tube may contain caesium alone, the thin top of the tube being broken by the action of a magnet on a ball. The envelope is baked at 155-165‹ C. for 3 minutes, more caesium is admitted and the cell baked again. When the sensitivity has risen to 15 microamps per lumen no further caesium is admitted, but baking is continued for 10 minutes or more so as to increase the sensitivity to 30 microamps or more per lumen. The filling may be xenon or krypton. Specifications 303,476, 319,734, [both in Class 39 (i), Electric lamps, Arc &c.], and 344,499 are referred to.

Abstract: 447,779. Cigarette-making machines. LERNER, F., 28, Burgerspitalgasse, Vienna. Dec. 7, 1934, No. 35181. [Class 130] In a machine for making filter-tip cigarettes in which a continuous tobacco filler is formed and cut into sections between which filter-tips are inserted and the composite filling is formed into a continuous cigarette rod, the distance between the cigarette rod and the filler is alternately increased and decreased by periodically varying the relative speeds of the cigarette rod and the tobacco filler. The tobacco is fed on a tape 3 through a channelshaped passage 2, pressed by a wheel 4 and cut by a knife 6 as it issues from a tube 5. The sections are deposited on a paper strip 7 which is carried by a tape 9 through a passage 8. Needles 17 on an endless belt 16 transfer filter-tips 12 from a slotted tube 19 into the gaps between the sections and the tips are detached when the edges of the tape 9 are wrapped around the rod. Either or both of the tapes 3, 9 are driven at periodically varying speeds through elliptic or eccentric gears from a common shaft and the filter tip is deposited when the speed of the tape 9 is a maximum or the speed of the filler a minimum. The cigarette rod preferably consists of double length tobacco fillers and filter tips which are bisected simultaneously by knives 13, 14. In modifications, the filter tips are supplied by moving grippers or suction means or by a stationary device.

Title: Photographic printing of cathode ray tube screen structure
IPC: G02B5/20
Filed: 1970-07-21
Abstract: 1,269,749. Luminescent screens. RCA CORPORATION. 21 July, 1970 [25 July, 1969], No. 35248/70. Heading H1D. [Also in Division G2] In a photo-resist process of manufacture of a luminescent screen, in particular a multi-dot screen for colour television, the intensity of the light used to expose the photo-resist may vary over the area of the screen, and this is corrected by means of a filter comprising finely divided, preformed, non - metallic, light - absorbing particles such as carbon having a mean diameter between 5 and 50 millimicrons, and preferably between 9 and 29 millimicrons. The filter may be formed by a photo-resist process using the same light field as is used in the manufacture of the screen, and may comprise a layer on the correction lens or on the wedge lens used in the "lighthouse " or on a separate optical element which may be disposed between the two lenses (Fig. 3, not shown) or between the lens system and the shadow mask. Filter, manufacture.-The lens on which the filter layer is to be formed is cleaned and rinsed and coated with a thin film of 0À05% gelatine solution; after drying this is rinsed in deionized water at 50 C. to wash away most of the gelatine and leave a thin monolayer precoating. This is coated with a light-sensitive composition comprising 120 g. carbon particles, 12 g. sulphated lignin powder dispersing agent, 42 g. non-ionic oxyethylene alcohol wetting agent, 1380 g. of gelatine, 10 kg of deionized water, 37 g. of a hardener such as 4,4<SP>1</SP>-diazidostilbene- 2,2<SP>1</SP>-disulphonic acid sodium salt which is a sensitizer for the gelatin, and 300 g. ammonium hydroxide solution. A quantity of this composition at 40 C. is poured on the lens which is spun to form a uniform layer 1 mil. thick. After cooling and drying, the lens is exposed in the lighthouse for about 2-5 minutes at about 45 foot candles. The exposed lens is placed in dilute potassium alum at 25 C. for 5 minutes to insolubilize the anionic dispersing agents and partially harden the gelatine. Unexposed material is then washed away in the three-compartment laminar flow trough shown in Fig. 4 filled with water at 50 C. which flows through a metal wool baffle 93, down across the filter plate 61 which has its coated side 71a downwards, and under a solid baffle 95. The water flow continues for 30 minutes and the inlet temperature of the water is then lowered to 15 C. to harden the gelatine. The solid baffle 95 is removed and when the outlet temperature of the water is below 20 C. the lens is removed and dried and is then ready for use.

A floor comprises a layer of resilient material laid on a sub-floor and covered by a foil of wearresistant synthetic material which is of a size and shape corresponding to the floor area to be covered and is stretched along its plane parallel with the floor surface and secured while still under tension along its boundary edges. The foil may be of or contain polyvinyl-chloride or be based on a polyamide or a polyethylene and is made by joining together strips of the material by sticking or welding with or without the use of supporting strips. The resilient layer may be of foam rubber, synthetic foam material or felt produced from animal, vegetable or mineral fibres. When the resilient layer is of foam rubber or synthetic foam material it may be stuck to the wear-resistant material. A wooden frame may be provided round the periphery of the floor area to be covered for the securing by nails of the wear-resistant material ; distance-pieces may be provided on the nails to prevent recesses being formed where the wear-resistant material is secured. Below the layer of resilient - material a further layer of material may be provided to compensate for any unevenness of the sub-floor or to provide additional heat and sound insulation. The sub-floor may be covered with sand in which insulating building slabs are then embedded or a layer of porous concrete, which may be mixed with bitumen or a synthetic resin to increase imperviousness to water, may be cast on the sub-floor. This additional layer may also be built up on a foundation of gypsum or produced as a xylolite finish. A layer of bitumen is preferably provided between this additional layer and the wear-resistant material. This may be done by coating the additional layer with bitumen or providing bituminised cardboard which may be coated with bitumen only on its under side. The bituminised cardboard may be covered with cork granules and then also constitute the resilient layer. In a further modification cork granules may be coated with bitumen or other water-repellant adhesives and formed into a stable layer. When felt is used as the resilient material it may be treated with preservatives. The thickness of the wearresistant foil may suitably be from 0.5 to 0.8 m.m. and the thickness of the resilient layer from 2 to 4 m.m.
