Title: Improvements in or relating to television or like systems
IPC: H01J31/26
Filed: 1936-11-05
Abstract: 484,574. Cathode - ray tubes. BAIRD TELEVISION, Ltd., and JONES, V. Nov. 5, 1936, No. 30096. [Class 39 (i)] In a television or like system an electrondischarge device is provided having a photoelectric cathode 2 upon which an image to be transmitted is projected, the photoelectrons emitted being arranged to form a charge image on a single - sided photoelectrically sensitive mosaic electrode 3, which comprises a plurality of discrete photoelectrically sensitive elements 4 at least partially insulated from one another and which is scanned by a light spot. The cathode 2 and elements 4 may be sensitive to light of different wave lengths so that the mosaic may be scanned with light different in colour from that forming the image on the cathode 2. The electrons emitted by the cathode may be multiplied by secondary emission from one or more secondary emitting grids as described in Specification 469,404 and the electron stream is focused upon the mosaic 3 by a magnetic coil 8 which may produce an intense focusing field immediately in front of the mosaic so as to prevent diffusion of the image charges and in this case the anode 6 is in the form of a grid parallel with the mosaic 3. A transparent metallic layer 5 is provided on the back of the mica sheet forming the support for the elements 4 of the mosaic, this layer being connected through a resistance 9 with the cathode 2. The mosaic 3 is scanned by a light spot which may be projected from either side of the electrode assembly, whereby electrons are emitted therefrom proportionally to the intensity of the electron image incident thereon, thus giving rise to image signals in the resistance 9. Suppressor grids may be provided between the anode 6 and the mosaic 3, and also adjacent the cathode 2. Image signals may also be obtained from a load impedance connected between the electrodes 3 and 6, or the photoelectrons emitted from the mosaic 3 on scanning may fall upon an electron multiplier consisting of a series of grids at gradually increasing potentials or the multiplier may comprise a series of coaxial cylinders of decreasing diameter arranged within the ring-shaped anode 6 which is then of larger diameter than that shown. The light spot for scanning the elements 4 may be obtained by covering the electrode 5 or the mica sheet of the mosaic with fluorescent material, this being scanned by a cathode-ray gun mounted within the envelope 1.

Title: Process for the treatment of white fraction of latex
IPC: C08C1/10
Filed: 1947-11-18
Abstract: Rubber with a low water absorption is obtained by causing the bacteria and enzymes present in natural latex to act on the white fraction of the latex for at least 44 hours at a pH of 6 to 9, and thereupon separating the white fraction into a cream and coagulating the cream.  The white fraction may be obtained by removing the yellow fraction by centrifuging at a suitable pH, by stirring the latex at a suitable pH, or by partial coagulation and removal of the yellow fraction.  Creaming may be effected by means of illis mannae meal solution, and coagulation by the addition of formic acid. Specification 594,938 is referred to.

Title: Multiple tube cooling device
IPC: F25B9/04
Filed: 1951-06-25
Abstract: 708,046. Cooling gases; tubular heat exchangers. GARRETT CORPORATION. June 25, 1951 [June 29, 1950], No. 30563/52. Divided out of 708,011. Classes 29 and 64(3) [Also in Group XXIX] Air or gas to be cooled is passed through banks of tubes 42, 43, 49, 57 in heatexchange relation with a coolant, and a valve 26 responsive to change in a condition affecting the density of the air or gas varies the quantity of tubes in action. The tubes 49, 57 are vortex tubes of the kind described in Specification 405,781. The tubes are arranged in a casing 11 and pressure air bled off the outlet of the jet engine compressor of an aircraft is supplied by a pipe 24 to a space 21 at one end of the casing and passes through the heat-exchange tubes 42, annular header 40 and heat-exchange tubes 43 to a space 18. Cooling air from the inlet of the compressor, which enters the casing at 36 and leaves at 38, as shown by the arrows 62, cools both the heat-exchange tubes 42, 43 and the vortex tubes 49, 57, which are of heat conductive material. From the space 18 the cooled compressed air passes to a dome 47 and to the tangential inlets 54 of the vortex tubes 49 which are continuously in operation. The ends 51 of the vortex tubes are closed and the cold air passes through a pipe 55 into the space to be cooled, e.g. the casing of an electric generator connected to the casing 11 by a fitting 56 with a clamping band 56a. The dome 47 communicates through a cylindrical slide-valve 26 with a space 16 divided into six sector-shaped chambers 34 by radial partitions 35 and the valve casing 25, shown developed in Fig. 4, has six openings 28 leading individually into the chambers 34 and spaced so as to be progressively opened by the cylindrical slide 27 of the valve. From each chamber 34 the cooled compressed air passes to the tangential inlets 54a of separate banks of vortex tubes 57 also cooled by the cooling air and closed at the ends 59, the cold air from these tubes issuing through pipes 61 to the fitting 56. The valve slide 27 is actuated by a bellows 30 so that as the aircraft rises more of the openings 26 are uncovered and more of the vortex tubes 57 brought into operation to compensate for the reduction of air flow through the individual tubes. Specification 708,011 also is referred to.

Title: Nisin-containing product
Inventor: HAWLEY HENRY BERNARD
IPC: A23C9/158
Filed: 1954-10-26
Abstract: Nisin is separated from a culture medium containing nisin and milk caseinogen by adjusting the pH of the medium to 4.5 to 5.5 to precipitate casein or paracasein together with absorbed nisin. The precipitation may be effected by acidifying the medium to pH 5.8 and adding acid to bring the pH to 4.5-5.5, or by the action of enzymes in which further acidification is effected by continued action of the nisinproducing organism on the milk medium; alternatively the milk medium may be acidified to pH 5.8, the pH adjusted to below 5.8 and then again adjusted to a value greater than 5.8, the casein separated furing this adjustment being removed prior to the main precipitation. Nisin concentrates may be extracted from the nisin-casein/paracasein complexes by employing aqueous buffer solutions of pH 2. Specification 683,423 is referred to, and Specification 738,655, [Group VI], is referred to in the Provisional Specification.ALSO:Infection of cheese by clostridium and thermophilic flat souring organisms is prevented by incorporating a solid nisin preparation made by bringing the pH of a cultive medium containing nisin and milk caseinogen to 4,5-5,5 and precipitating casein or paracasein, which contains substantially all the nisin, and pressing the precipitate to a cheese-like product, or drying and powdering it.  Incorporation of the nisin preparation in processed cheese is conveniently by way of the melting or emulsifying salts. Specification 683,423 [Group IV(b)] is referred to and Specification 738,655 also is referred to in the Provisional Specification.ALSO:In making solid preparations of nisin, the pH of a culture medium containing nisin and milk caseinogen is brought to pH 4.5-5.5 and the precipitated casein or paracasein, which contains substantially all the nisin, is separated.  Casein may be precipitated by acid at pH 5.8 and additional acid then added to bring the pH to within the range 4.5-5.5.  Paracasein may be precipitated by the action of enzymes, the further acidification being effected by continued action of the nisin-producing organism on the milk medium.  The separated casein or paracasein may be dried and powdered, or may be pressed to a cheese-like product.  The production of nisin may be conducted at a pH above 5.8, the pH adjusted to below 5.8 and then again adjusted to a value greater than 5.8, the casein separated during this adjustment being removed prior to the main precipitation.  The nisin preparations may be incorporated in cheese to prevent infection by clostridium and thermophilic flat-souring micro-organisms; incorporation in processed cheese is conveniently by way of the melting or emulsifying salts.  Purer nisin concentrates may be extracted from the preparations by employing aqueous solutions of pH2.
