Patent GB-809509-A (GB)
Title: Improvements in and relating to apparatus for separating liquids of different densities
IPC: C10G33/06
Filed: 1955-10-19
Abstract: 809,509. Gravity-separation apparatus ; filters. MULLER, J. Oct. 19, 1955 [Feb. 8, 1955], No. 29874/55. Class 46. Apparatus for separating liquids of different densities comprises a vessel divided by a partition into an admission chamber and a separation chamber, the partition being provided with several separation cartridges or separation layers, a sump on the separation chamber containing a float which controls the discharge of the heavier liquid from the sump and also a valve controlling the flow of the mixture to the admission chamber or a valve controlling the discharge of the lighter liquid. Each cartridge consists of a central perforated tube 62 surrounded by annuli formed of a pile of annular discs 65a or bands 65b coiled edgewise clamped by an end cap 68 against a flange 60 insertable through an aperture in a partition wall and secured therein by wing nuts. The cartridge may be surrounded by one or more similar cartridges 71 . . 73. In a cylinder 78 having a sump 81 a number of cartridges 65 are mounted in parallel on a partition dividing an admission chamber 79 from a separation chamber 80. The lighter liquid rises over a weir 98 in the latter chamber to be further purified at 99 before being discharged through an outlet 100. The heavier liquid sinks into the sump 81 and a regulating chamber 82 beside it. Liquid to be treated enters this chamber through lateral apertures in an inlet tube 96, the apertures being regulated by a bell 95 raised and lowered by a float 87 in the sump 81, the float also actuating a rotary slide valve 93 controlling the discharge of heavy liquid through an outlet pipe 94, to open the valve 93 as the valve 95, 96 closes. In a modification, the partition 102 has a central aperture 113  leading a further inlet chamber in which are mounted additional cartridges 112. The regulation chamber 105 opens from the admission chamber 103 and when the presence of heavier liquid raises the float 110 the inlet 108 is closed and a valve controlling a passage 107 to the sump 106 is opened to let the liquid drain away. In the sump 106, a float 126 which controls an outlet valve 127, similar to the valve 93, also actuates an inverted bell 123 which regulates apertures 122 in a tube leading from the separation chamber 104 to a complementary purifier for the light liquid. The liquid enters the lower part of a chamber 118, passes through a membrane 119 and escapes by an outlet 120 disposed some way from the top of the chamber which thus provides an air cushion adapted to cause some back wash through the cartridges to clean them. A spring pressed piston 116 in a chamber 115 on the top of the separation chamber functions similarly. Separation layers may replace the cartridges 112. Specification 769,713 is referred to.

Patent GB-533697-A (GB)
Title: Improved method of and device for reproducing cross-sections of bodies by means of x-rays
IPC: A61B6/02
Filed: 1939-11-15
Abstract: 533,697. R÷ntgen-ray apparatus. PHILIPS LAMPS, Ltd. Nov. 15, 1939, No. 30141. Convention date, Nov. 18, 1938. Addition to 530,477. [Class 98 (i)] A modification of the method of obtaining X-ray images of a section of a body forming the subject of the parent Specification consists in avoiding the necessity o forming a series of strip-forn pictures, which have sub sequently to be trans versely enlarged and superimposed, by moving the sensitive surface during the exposure of each image relatively to the beam in a direction normal to the plane of section of the body, the images so widened being superposed with angular displacements between them produced by rotating the sensitive surface about a fixed point to the same extent as it is rotated about an axis of the body, normal to the plane of section. In the apparatus shown X-rays, originating at the point 1 and limited by a slit 4 to a narrow beam traversing a section of the body 2, are received on a film 5 held on the surface of a cylinder 6, which during exposure is rotated on its axis so that the film receives an image consisting of a lateral expansion of the strip-image formed by the slit. The X-ray source 1 and the cylinder 6 are then rotated through a small angle about the axis 10 of the body, and the film 5 is rotated through the same angle about the axis 1-9, the exposure being them repeated. As explained in the parent Specification, the superposition on the film of a number of images made in this way from angular positions extending all round the body 10 gives a picture of the cross-section. The movements may be made continuous, as in the apparatus shown in Fig. 5, in which the film is secured to a flexible plate 12 held to the surface of the cylinder 11 by channel members 13 engaging its edges, so that it may be rotated by a shaft 14 driven by gears operated by a fixed worm 17 on a stub shaft on which one end of the cylinder is journalled. The ratio of the revolutions of the plate 12 to those of the cylinder 11 may suitably be 1 to 1200.

Title: Improvements in regenerative gas-fired furnaces
IPC: F23L15/02
Filed: 1923-12-04
Abstract: 208,700. Huessener, K. Dec. 21, 1922, [Convention date]. Gaseous-fuel furnaces.- In a gas-fired regenerative furnace, the air and gas are fed to the furnace through stabilizing-chambers connected to pressure-controlled mechanism for regulating the supply of air to maintain the air and gas pressures in the chambers substantially equal or at a substantially constant ratio, a hand - controlled valve being provided in the conduit between the air chamber and the furnace. Where a portion of the air for combustion is mixed with the gas before it enters the furnace, the supply of air for the mixture is controlled in accordance with the gas supply and the supply of air for effecting the complete combustion of the gas is controlled in accordance with the supply of the mixture to the point of ignition. In the apparatus shown in Fig. 1, air is supplied by a fan 2 through a pipe 3, provided with a regulating valve 4, to a stabilizing-chamber 5 which communicates through a pipe 6 having a hand-controlled valve with the air reversing valve mechanism of the furnace. Gas is supplied through a valve-controlled pipe 9 to a stabilizing-chamber 10 leading to a pipe 12 and the gas reversing valve mechanism. The outlet ports a, b of the chambers 5, 10 are of such size as to maintain the supply of air and gas in the desired proportions with the gas and air at equal pressure. To ensure the. pressures being equal, the chambers 5, 10 are connected by pipes 14, 13 to inverted bells 16, 15, Fig. 3, having their lower ends immersed in a liquid in a vessel 17 and supported on a pivoted beam 18. In the event of an increase of gas pressure, the bell 15 is raised and its movement is communicated through the beam 18 to rod 20, lever 21, bellcrank lever 26 and valve mechanism 25 controlling fluid pressure to a cylinder 23. The piston of the cylinder is operated to move the frame 30 which is connected by suitable Links and levers to the valve 4 of the air-supply pipe 3. The movement of the frame 30 is limited by causing it to operate through a cam 32 an inclined bar 31 pivoted to a swinging post 28 connected through the link 27 and bell crank 26 to the valve mechanism 25. In the modification shown in Fig. 2, a portion of the air supplied by the fan 2 is conveyed by a pipe 33 to a stabilizing-chamber 34 and gas is supplied to a stabilizing-chamber 36, the gas and air being supplied in the desired proportions to the mixing-chamber 38. The air supplied through the pipe 33 is regulated by a valve 35 controlled in a similar manner to the valve 4 described above by connecting the cliambers 34, 36 by pipes 14<a>, 13<a> to a similar chamber 17. The valve 4 is regulated in accordance with the pressures in the chambers 5 and 38.
