IPC: A23C15/04
Filed: 1924-08-12
Abstract: 242,363. White, A. E.,( Milk Oil Corporation). Aug. 12, 1924. Butter. - Butter is manufactured by mixing melted milk-oil at a temperature of 96‹ F. or over with an emulsifying agent consisting of milk or some milk derived substance, until the fat globules are approximately the same size as in natural milk or cream and then cooling to a temperature at which the fat globules have a tendency to stick together, the emulsion being then pressed or squeezed with a spoon, paddle or roller to cause the separation of the butter. As specific examples (i) 6 parts of milk oil at about 140‹ F. are mixed with one part. of dry skim milk powder and one part of water added; the mixture is stirred and cooled to 60‹ F. and then squeezed, or rolled or pressed to separate the butter which is then worked in the usual way : (ii) 60 parts of milk oil and 40 parts of fluid milk, skim milk or reassembled milk, are mixed at 140‹ F. and passed through a mechanical emulsifying machine; the resulting paste is stirred, cooled to 60‹ F., and squeezed or rubbed as before : (iii) the same mixture is gradually cooled and stirred instead of being passed through the emulsifying machine, until it emulsifies; it is then cooled to 60‹ F. and rubbed as above.

Abstract: 837,910. Spinning glass. SCHULLER, W. H. W. June 3, 1958 [June 21, 1957], No. 19577/57. Class 56. Filaments are produced from .rods of glass or other thermoplastic materials by a process in which the rods are continuously drawn from a source of supply, the rods being vertically disposed in end-to-end relationship, and fed into borings in directly or indirectly heated receiver members in which borings the adjoining ends of the rods are fused together in a plastic state, the filaments being simultaneously drawn off from the plastic mass as it flows from the borings. As shown in the Figures accompanying the Provisional Specification the rods 2 are supported on an inclined guide rail 3 which is rocked in the directions of the arrow A by an eccentric 4 to ensure continuous supply of rods. The foremost rod 2<SP>1</SP> comes up against a stop 5 so adjusted that the rod 2<SP>1</SP> stands loosely upon the previous rod 2<SP>11</SP>. This rod 2<SP>11</SP> is moved downwards in the direction of arrow B by feeder means such as two oppositely disposed draw rollers or discs 7a and 7b. If desired, the rod may then pass through a cooling device 10. It is finally passed to a flanged sleeve member or receiver 8 supported in a block of fine clay 9 containing heating means 27. The temperature of the receiver rises over its cross-section from the inlet 15 to the outlet 16 so that the rods fuse one to the other and form a residue of plastic material 13 from which the filament may be drawn. The borings in the receiver may be cylindrical or conical, and if desired two or more filaments may be drawn from the same boring e.g. as shown in Fig. 3, where the boring 25 merges into conical bores 26.

Title: Improvements in cathode ray tubes comprising luminescent material excited by the cathode ray
IPC: H01J29/18
Filed: 1937-07-19
Abstract: 491,748. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd., JESTY, L. C., and SHARPE, J. July 19, 1937, No. 19951. [Class 39 (i)] A cathode-ray tube comprises a mass of loose powdered luminescent material and a solid member, preferably a portion of the envelope, so shaped and located relative to the electrodes of the tube that, when the tube is suitably positioned, the powdered mass resting on the member can form under the influence of gravity a smooth level surface on which the cathoderay is incident. The invention is particularly applicable to television receivers of the kind in which the image of the screen is optically projected on to another surface, and in which the risk of burning the screen, due to the high intensity of the beam, is large, since in the screen of the invention any burnt spot can be' dispersed and the screen reformed by-shaking and tapping. Moreover, as no binder, which is stated to decrease luminescence, is present, the screen can be increased in thickness to increase brightness. The support for the screen may be a close-fitting tray, or the base of the tube, and may be a portion of a sphere of large radius, so that by tilting the tube and resettling the screen the angle of incidence of the ray may be varied. Linear conductors arranged between the scanning lines, or spikes projecting into the screen may be used to conduct away the screen charge. To facilitate transport the screen material may be carried in pockets provided with doors which may be opened by magnets, or, as described in the Provisional Specification, adjustable flaps may prevent the screen material touching the electrodes during transport.
