Title: Gear pumps
IPC: F04C2/14
Filed: 1926-02-22
Abstract: 248,005. Appel, G. Feb. 23, 1925, [Convention date]. Movable - abutment type; packing drums. -The gear-wheels of a Roots-blower type of pump for delivering liquids such as viscose under pressure, rotate in a chamber formed in a disc which can move in its own plane on the casing to fit closely to the gears and prevent leakage from the inlet to the outlet channels. The gears h rotate on shafts o<1>, o<2> in a chamber g, g in the disc f which is contained in the recess c in the casing a with a peripheral clearance of about one millimeter. When the viscose is supplied under pressure along the channels j and the gear wheels are at rest, the fluid causes the disc f to press tightly round the gears at their outlet side, preventing leakage. When the gears operate to supply the viscose through the outlet i, under further pressure, the fluid presses the disc in the reverse direction, preventing leakage to the inlet side. An annular channel m connected to the outlet i contains fluid under pressure which further presses the disc to the gears.

Abstract: 1,107,484. Photographic film assemblies. INTERNATIONAL POLAROID CORPORATION. Feb.4, 1966 [Feb.4, 1965], No.5077/66. Heading G2A. An image recording sheet 10 and an image receiving sheet 12 having a mask sheet 16 secured thereto are brought together for image transfer by rollers 26, 28 in a photographic camera which rollers rupture a container 22 to spread processing liquid between the sheets as they are advanced. The mask sheet 16 has apertures 18 defining image receiving areas in the sheet 12. The roller 28 is provided with a collar (30) Figs.3, 4 (not shown) at each end, by means of which pressure on the image receiving area is reduced as it passes through the rollers (Fig.3), thus allowing of even distribution of the processing liquid. After an image receiving area has passed through the rollers, the collars (30) depress the sheet (10) into slots (40) in the mask sheet (16) (Fig.4), thereby forming a tight seal preventing escape of excess liquid when the sheet assembly is torn off from the sheets remaining in the camera. The sheets 10, 12 are backed with opaque material so that processing can safely take place outside the camera.

Title: Improvements in or relating to electron beam convergence systems for cathode ray tubes
IPC: H01J29/70
Filed: 1954-02-22
Abstract: 750,644. Cathode-ray tubes. RAULAND CORPORATION. Feb. 22, 1954 [Feb. 24, 1953], No. 5115/54. Class 39 (1). In a tri-colour television receiver in which the colour emitted by the screen depends on the angle of approach of an electron beam, three beams are formed by separate guns and projected in paths symmetrical about the tube axis and are deflected so as to approach a common focal point approximately in the plane of the screen by electrodes 36, 37, Fig. 2, between which a radial field is set up. The invention is also applicable to forms with two or more than three guns and colours, or with a single gun the electrons from which are initially diverted at regular time intervals to a plurality of radially spaced positions forming virtual beam sources, or to other plural beam reproducing tubes employing visually responsive directional screens. The screen in the forms shown in the drawings comprises a flat surface made up of dot triads and a shadow mask to limit the crosssection of the beams to the area of one dot triad, but may alternatively have pyramidal luminescent areas. Electrode 37 has diaphragm 38 with beam passing apertures 39, 40 and is connected to wall coating 31; it is insulated from inner electrode 36 by glass bushing 41 and carried from the tube wall by spring clips 38A. Electrode 36 is connected to a D.C. source which is preferably coupled to the scan generator. The scan coils may be replaced by electrostatic means. 36, 37 may be at 20, 19 kv. respectively, the potential difference between them being variable to adjust the distance to the point of convergence. Preferably the focal distance is varied in synchronism with the scanning by using the scan generator to control variations in D.C. potential of the source applied to electrode 36. In another embodiment, Fig. 4, the converging structure comprises three pairs of plates 45, 51; 46, 52; 47, 53 with individual leads 48, 49, 50, 54, 55, 56. This allows for individual adjustment of the beam deflecting fields to correct for mechanical or electrical differences in the guns, and provides more uniform transverse fields so as to minimise distortion of the beam cross-section. All forms of the invention avoid the spherical aberration and distortion of a conventional focusing lens, since no such lens is required. Such aberration causes elliptical distortion of a circular spot or similar distortion of beams of square or hexagonal cross-section, and consequent colour contamination or fringing effects.

Abstract: 726,563. Laminated sheet materials. DOW CORNING, Ltd. Feb. 26, 1953 [March 20, 1952], No. 5367/53. Class 140. Mica having a particle size of at least 1 mil. cross-section is deposited from a slurry on to a glass cloth and the whole is impregnated with an organosiloxane resin soluble in an organic solvent and cured at elevated temperatures until a tuck-free laminate is obtained. The mica may be slurried in water, alcohol or hydrocarbon solvents, or in a solution of the siloxane. In the latter case, it is preferred that the resin solution should have a viscosity of below 50 centipoises at 25  C. Suitable solvents include ethanol, butanol, hydrocarbon solvents and ethers. The resin may include siloxane units containing alkyl, aryl, alkaryl, aralkyl, alkenyl or alicyclic radicals attached to the silicon by C-Si linkages and of formula RSiO 3/2 , R 2 SiO, R 3 SiO 1/2 . SiO 2  units may also be present. The average ratio of R radicals to Si atoms may vary from 1 : 1 to 1.7 : 1. The preferred resins contain both methyl and phenyl radicals attached to either the same or different silicon atoms, and containing units of formula CH 3 SiO 3/2 , C 6 H 5 SiO 3/2 , (CH 3 ) 2 SiO, (CH 3 )C 6 H 5 Si) and (C 6 H 5 )SiO. The mica may be deposited by pulling the slurry through the cloth by vacuum or continuously by passing the glass cloth as a belt through a tank of the slurry, the cloth moving over hollow rollers having openings through which the solvent is drawn by means of a vacuum. Curing may be to an infusible stage or, when making a multilayer laminate, to the tack-free stage only. Catalysts such as carboxylic acid salts of sodium, potassium, cobalt, lead, zinc and tin may be used in amounts less than 1.0 per cent of the weight of the resin may be employed to facilitate curing. In an example a water slurry of mica flakes is poured over a glass cloth, the water being removed by a vacuum. After drying, the laminate is dipped into a 5 per cent toluene solution of a siloxane resin containing monophenylsiloxane, monomethylsiloxane, dimethylsiloxane and phenylmethylsiloxane groups, dried and cured. It is then dipped into a 60 per cent toluene solution of a siloxane resin containing monophenylsiloxane, monomethylsiloxane and dimethylsiloxane groups and also containing dibutyltindiacetate and lead 2-ethylhexoate as catalyst. After curing at 110 C. until tack-free, the laminate is wrapped round a heated mandrel and cured to form a tubular product. Specification 726,567 is referred to.
