Title: Improvements in Regenerative Coke Ovens or the like.
Inventor: BLOXAM ARTHUR GEORGE
IPC: C10B5/10
Filed: 1916-09-23
Abstract: 107,879. Bloxam, A. G., (Evence, Coppee, et Cie). Sept. 23, 1916. Coke ovens.-In a regenerative system for cokeovens, a number of regenerator units are arranged in parallel between collecting and distributing flues common to the whole battery. The arrangement is shown in Fig. 5 applied to a battery of ovens which can be heated either by poor or rich gas. During the period in which the products of combustion are heating up the regenerator units 3', 10', poor gas from the supply pipe 1 passes through the units 3 into a flue 5 running the length of the battery and in dampered communication with a flue 8, Fig. 6, under each heating wall. Air is admitted at the reversing-valve 25 to the flue 9, and passes through the units 10 to a flue 14 in dampered communication with sole flues 17 under alternate ovens. Combustion takes place in the heating wall, and the products escape, some through the sole flues 17', flue 14<1>, regenerator units 10<1>, and flue 9<1>, and the remainder through the flues 8<1>, 5', regenerator units 3', flues 23<1>, and reversing-valve 26'. The two streams unite, and pass to the chimney flue under control of the reversing-valve 25. During this period of working, the valve 26 is closed. When using rich gas, which is supplied through flues 29, 30, without preliminary heating, both valves 26, 26<1> are opened, and air is heated in the whole of the regenerator units on one side of the battery. When applied in connexion with ovens heated by rich gas only, the gas collecting and distributing flues are omitted. The regenerators are preferably arranged end to end in two lines of similarly functioning units, but the two lines may consist wholly of air and gas regeneratcrs, respectively. The relative arrangements of the regenerators of flues may be varied, for example by placing the two lines of regenerators close together, or by arranging all the flues between the two lines.

Filed: 1953-05-15
Abstract: 759,151. Television. CINEMA-TELEVISION, Ltd. May 14, 1954 [May 15, 1953], No. 13672/53. Class 40 (3). A circular area is scanned by means of an aperture of constant area moving in a spiral path concentrically with said area. The scanning aperture is defined by the conjunction of a spiral slot 10 in a first rotating disc 3 with a radial slot 12 (or a spiral slot of opposite sign and inverse exponent to that of slot 10) in a second rotating disc 4 mounted coaxially with disc 3 the relative speed of rotation being such that the aperture traces a multi-turn spiral.. To prevent leaving a permanently exposed portion at the centre of the two discs due to both slots overlapping at this point a shutter member 13 carried by disc 4 is arranged normally to obscure the central portion of slot 12 but to be moved so as to expose this portion by the action of a cam member 11 carried by disc 3 and which operates on a pin 18 connected to shutter 14 and passing through a slot in disc 4 when the innermost part alone of slot 10 is in conjunction with slot 12. The arrangement described may be employed either to produce a moving spot of light or to scan an illuminated area and generate electrical signals in a co-operating photo-electric cell. Applications of the invention referred to are, the examination of containers to detect foreign bodies, television principles applied to microscopy and radar display simulation.

Title: Improved water-cooled spreading roller or rolling-machine roll for the manufacture of plate-glass and glass sheets of all kinds
IPC: C03B13/16
Filed: 1926-06-01
Abstract: 257,892. Soc. Anon. des Ateliers de Construction et Fonderies de Jeumont, Anciens Etablissements T. Haut. Sept. 5, 1925, [Convention date]. Rolling. - Relates to a watercooled roller used in apparatus for producing plate glass. According to the inrention, the water is supplied through one or two axial tubes to the middle of the interior space of the roller and allowed to escape through both ends. The roller is thus cooled more uniformly, and distortion due to irregular heating is minimized. In the construction shown in Fig. 2, the water is supplied through a single tube 9 passing through one of the trunnions, D, and the flow divides and passes out through passages 4, 4<1>, formed in both trunnions. Spaces 11, 11', of larger diameter than the space in the interior of the cylinder, are formed at the ends, and the water passes through the spaces into the passages 4, 4' bv way of radial passages 3, 3<1>. The purpose of this construction is to prevent air from becoming trapped in the interior of the roller. In another construction, the trunnion C is also fitted with a water supply tube similar to the tube 9. The roller may also be provided with a central core 19, Fig. 5, to increase its weight. The core has a central partition 19<1> and the water, supplied to its interior through axial tubes 9, 9<1>, passes through holes 10 into the interior of the outer cylinder and escapes at the ends.

Abstract: <PICT:0454176/III/1> In the de-waxing of oils, the oil is diluted with a solvent consisting of a mixture of at least two components, one of which is selected from the group, dichloro ethane, dichloro propane and the corresponding bromine or fluorine compounds, and the other from the group, dichlor ethylene, trichlorethylene, dichlor propylene, trichlor propylene, and the corresponding bromine or fluorine compounds, whereupon the mixture is chilled and the fraction rich in wax is separated.  The process may be effected in a single stage, or preferably the fraction containing wax and some oil first separated is further diluted and chilled to a lower temperature. Residual oils, hydrogenated oils containing wax, and asphaltic residuals may be treated.  Wax may be separated by filtration, sedimentation or by centrifuge in which both crystalline and amorphous waxes are removed.  The diluent mixtures may contain benzol and also carbon tetrachloride, fluoride or bromide.  Wax-containing oil is withdrawn from a tank 1 and passes to a chiller 5 to which 3 volumes of a solvent mixture of dichlorethane and dichlor ethylene are admitted from tanks 3, 4. Chilling may be effected by evaporation of part of the solvent to a temperature of 0 DEG  to -10 DEG  F. by slow or shock chilling.  The chilled mixture containing separated wax passes to a mixer 6 where oil and solvent are added from a later stage.  The mixture is then freed from wax in a centrifuge 7 of the type described in Specification 446,607 or 446,608, and the de-waxed oil is withdrawn through a pipe 8.  The separated wax containing raw oil and solvent passes to a chiller 9 to which solvent is added through a pipe 10, and the mixture is fed to a centrifuge 11 preferably of the type described in Specification 418,939.  Hard wax is removed through a pipe 12 and the oil solvent is either returned to the mixer 6 through a chiller 13, or distilled to recover solvent and oil.  The dewaxed oil may be finally treated with acid or clay in the presence of a solvent.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 456,122.  This subject-matter does not appear in the Specification as accepted.
