Title: Improvements in and relating to devices for washing pipelines
IPC: A01J7/02
Filed: 1964-11-04
Abstract: 1,013,030. Washing pipelines. ALFALAVAL A.B. Nov. 4, 1964 [Jan. 8, 1964], No. 45024/64. Heading F2N. A device which flushes a pipeline 1 with water before and after it has washed it with a washing- liquid comprises a mobile unit 3 in which are arranged (Fig. 2, not shown) containers for the liquids, pipelines, valves, a sequence control device which is regulated at 15, an electricity supply from 13, a cold water supply from 12, and a controlled heating element in the working liquid container. The water and washing liquid containers are situated side-by-side with a heat insulating air-gap between them and are fitted with float valves which control their water supply. A closed container for air is situated in the washing-liquid tank. To ensure that the temperatures of the liquids do not rise above required maxima (30 C. for water, 65 C. for washing liquid) it is arranged that each container shall be continuously leaked away at a controlled rate and replenished with cold water. A closed container (details not shown) houses a supply of foam plastic plugs. For milking, the pipeline 1 is connected to a collector vessel 5 having an outlet 8 to a pump 7 which operates to empty the vessel 5 when it reaches a given level. A vacuum pump 6 connects with the vessel 5 and with the device through a pipe 11. The pump 6 operates continually to effect both the milking and the washing processes. After milking, the empty vessel 5 is connected at 10 to the inlet of the device and the outlet of the device is connected at 2 to the end of the pipeline 1. The operation of the sequence control device then causes the pipeline to be flushed with tepid water 3 which, when it fills the vessel 5 to the given level is pumped out by the pump 7 until the water container in the unit 3 is empty. The latter container then refills and for the next two minutes air only is sucked through the pipeline 1. This is followed by the warm washing fluid, which is followed in turn by more air, by a second washing with water, and finally by about 5 minutes with air only. The sequence control device then releases the foam plastic plugs, which are slightly oversize and are sucked through the pipeline 1 to dry it.

Title: A device for the manufacture of metallic conduits
IPC: B21D26/02
Filed: 1961-12-19
Abstract: 929,386. Making composite tubes; jointing by tube expanding; flanging. L. CAZZANIGA. Dec. 19, 1961, No. 45505/61. Classes 83 (2) and 83 (4). A device for making composite tubes consisting of an inner tube which is expanded by hydraulic pressure into engagement with the inside surface of a surrounding outer tube comprises a chamber 1 in which the tubes are placed, a first end header 12 for adjustably housing a tapered hollow cylinder 11, the interior of which can be vented to the atmosphere, said cylinder engaging in one end of the inner tube 10, a second end header 3 in which is slidably housed inside a chamber 4, a second tapered hollow cylinder 7 which engages in the other end of the inner tube 10 said second cylinder being in permanent communication with a source of hydraulic pressure P. The inner tube may be of steel and the outer tube may have cast iron fins 2<SP>1</SP> and end flanges 2. In operation, after the tube assembly has been positioned and clamped in the chamber 1 fluid pressure is applied from the pump P and the valve 14 is held open until all air is expelled. As the fluid pressure rises the tube 10 shortens as it expands and the end flanges and outer tube follow this movement. The cylinder 7 also follows the tube 10 due to the hydraulic pressure acting on its end face and thus fluid-tight contact with the tube is retained. In a modification the second header includes ball valves 23, Fig. 2, for admitting low pressure fluid through a passage 25 for filling the apparatus with water and at the same time exhausting the air. High pressure fluid is introduced through inlet 26 to effect the jointing operation.

Filed: 1975-11-04
Abstract: 1523339 Colour television tubes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 Nov 1975 [14 Nov 1974 (2) 19 Dec 1974 (7)] 45809/75 Heading H1D A colour television image projection system including a screen on which the television images of different colours are projected and superimposed, and, within a single envelope, two or more arrangements each including an electron gun vertically and horizontally scanning a phosphor target to form thereon an entire television image of a particular colour, and a Schmidt optical system disposed opposite to the target and including at least a spherical mirror for projecting the image displayed on the target on to the screen. In Fig. 7, green, blue, and red guns 19, and their corresponding phosphor screens 22, are arranged in delta formation, the beams being scanned over the screens by the common deflection coil 23, and each screen housing an associated part-spherical mirror 24 of a Schmidt optical system, the three colour images being thereby projected through the Schmidt correcting lens 25 to be superimposed upon the final screen. Magnets or electrodes 20 and 21 in the electron-optical systems permit adjustment to align the three images on the final screen, and to correct for distortion. The phosphor screens are supported by arms 27 within tubes 28, overlapping portions (shown cross-patched) of the three part-spherical mirrors being removed, and shield plates 26 restricting the passage of light from a given phosphor screen to its associated mirror. In other disclosed embodiments: an in-line rather than a delta arrangement of guns may be empolyed, the phosphor screens similarly being in-line and either parallel (Fig. 5, not shown) or-to provide a smaller device-perpendicular (Fig. 14, not shown) to theline of the guns; and only two guns may be employed, one associated with a green phosphor screen, to which colour the eye is most sensitive, the other being associated with a red/blue screen and beam indexing system (Fig. 8, not shown). The optical axes of the three projection systems may be parallel (Fig. 19, not shown), in which case adjustment of the superimposition of the three colour images is achieved by D.C. electric or magnetic deflection of the images on the phosphor screens. The electron-optical systems may be arranged such that, in the absence of an input signal, the beams are displaced from their respective phosphor screens, to prevent ion burn. The consequent D.C. deflection of the beams on to their respective screens upon the receipt of video signals is affected by variation of the gun high voltage supply; this, together with the resulting defective colour reproduction of the final image, may be avoided by controlling the D.C. deflection of the beams on to their respective screens in response to variations in the high voltage supply, and a circuit for this purpose is disclosed (Fig. 23, not shown).

Abstract: 1,073,999. Stabilizing photo-chromic images. NATIONAL CASH REGISTER CO. Nov. 12, 1965 [Jan. 29, 1965], No. 48189/65. Heading G2C. Stable photo-chromic images are produced by imagewise exposing a layer containing a spiropyran to produce a temporary image, and before, during or after exposure treating the layer with an acid gas to form an acid complex and converting the complex into an acid-base reaction product by reaction with a basic chromogenic material which is capable of changing colour in the presence of the acid complex to produce a stable image. The photo-chromic layer may contain the chromogenic material or this may be applied in a solution to the layer containing the acid complex. Specified chromogenic materials are N-halophenyl derivatives of leucaurimine, acyl auramines, rhodamine B, lactams, styryl dyes and 4, 4', 4", 4"' (oxydimethylidene)tetrakis (N, N dimethylaniline). Reversed images may be produced by overall exposure to ultraviolet light followed by imagewise exposure to green light when the spiropyran reverts to the uncoloured form followed by treatment with the acid gas (e.g. sulphur dioxide, boron trichloride or iodine) and the chromogenic material. The background areas of the exposed material may be fixed by washing out the spiropyran with a solvent. Reference has been directed by the Comptroller to the Specifications 1, 30, 217 and 1, 030, 219.
