Patent GB-653357-A (GB)
Title: Improvements in calcining decrepitating rocks including limestone
IPC: C04B2/10
Filed: 1948-06-23
Abstract: <PICT:0653357/III/1> Decrepitatable dust-forming solids, particularly lime-bearing materials, are heat-treated by a multi-bed fluidized process, in which the gases rising from a bed are treated for the reduction of their dust content before being passed to the next bed. As shown, the finely-divided material is fed by screw 14 to a preheating bed 62, overflowing through pipe 53 to calcining bed 20, and thence through pipe 21 to cooling bed 35 from which it is discharged through pipe 46.  Air is supplied to windbox 34 to fluidize bed 35, and passes through partition 25 into bed 20 wherein it combines with fuel supplied through conduit 22.  The dust-laden gases pass through pipe 40 to cyclone 42, the separated dust being sent either into the cooling zone or combined with the cooled product.  The dust-diminished gases pass to zone 66 and thence through partition 50 into the preheating zone.  In starting up the apparatus, additional fluid or fluidized fuel is supplied through conduit 28.  Hydrocarbon oils, coal gas, natural gas and powdered coal are specified as fuels.

Class 23 [Also in Group XXVI] In a hydro-extractor comprising a container rotatably driven by a current of air produced by a blower and directed on to turbo blades or the like, the maximum speed of the container is limited by means responsive to the container speed and adapted to close partially one or more openings through which air is supplied to the blower. The container is in the form of an annular drum 10 supported for rotation about a vertical axis upon a ball and bearing 16, 17 at the upper end of a vertical pillar 18 mounted in a rubber bush 22 and disposed within the tapered, inner peripheral wall 14 of the drum. Air from an electrically driven blower 11 mounted on the cover of the apparatus passes through driving blades 24 and returns by upward flow through the space within the wall 14 and through vertically spaced sets of openings 12, 13 in the latter. A disc valve 19, provided with a peripheral rubber ring 20, is mounted for vertical sliding movement on the pillar and is sucked upwardly during operation till it reaches a position when its edge is in close proximity to the wall 14 above the lower set 13 of openings, so as substantially to close the upper set 12. In a modification the lower part of the wall 14 is cylindrical to provide a clearance for the valve, and the upper part is of reduced section corresponding substantially to the valve diameter. The driving surfaces on the drum may, instead of vanes, be constituted by the walls off ducts provided in a locally thickened part of the drum wall.

Patent GB-912373-A (GB)
Title: Process for the oxidation of hydrocarbons
Inventor: BENICHOU SAMUEL
IPC: C07C51/21
Filed: 1959-05-22
Abstract: <PICT:0912373/IV (b)/1> In a process for the oxidation of hydrocarbons, e.g. the oxidation of naphthalene to phthalic anhydride, wherein a mixture of hydrocarbon vapour and oxygen-containing gas is passed over a catalyst disposed in stages, and a further quantity of hydrocarbon is injected between two successive stages, there is simultaneously injected a cooling agent in order to diminish the danger of explosion.  A mixture containing 35 g. of naphthalene in 1 cubic metre of air is fed at 350 DEG C. through duct 1 into a chamber A containing catalyst (e.g. vanadium oxide or molybdenum oxide), wherein partial oxidation of naphthalene to phthalic anhydride occurs and the temperature of the mixture rises to about 370 DEG -400 DEG C.  On leaving chamber A, the mixture is conducted through duct 2 to chamber B which also contains catalyst. Disposed within the duct 2 is a diffuser 3a into which are fed, through ducts 4a and 5a respectively, water and naphthalene.  The orifice of duct 5a may be surrounded by air admission nozzles 9a which prevent the formation of a local excess concentration of naphthalene.  Chamber B thus receives a mixture which is enriched in naphthalene, and cooled to approximately the initial temperature. The oxidation continues in chamber B and, from there, the mixture passes to catalyst chamber C by way of duct 6, which also comprises a diffuser 3b into which water, naphthalene and air are fed through ducts 4b, 5b, and 9b.  Chamber C is succeeded by catalyst chamber D, into which the mixture flows through duct 7 comprising diffuser 3c, into which opens the single duct 4c for the admission of cooling water.  Chamber D is intended for the complete exhaustion of the naphthalene.  The duct 8 leads to condensation chambers or a washing tower.

Abstract: 1371431 Ignition systems NIPPON DENON CO Ltd 17 April 1972 [19 June 1971] 17663/72 Heading F1B When the contact breaker points 3 are in the open position the capacitor 18 is charged. Also the controlling transistor 4 is in a conducting state and the transistors 5 and 6 are in a non-conducting state. When the contact breaker points 3 are closed the transistor 4 is put in non-conducting state. Because the capacitor 18 is connected to the output terminal of the transistor 4 through the resistor 11, the base voltage of the transistor 5 is increased and so the transistor 5 conducts. When the transistor 5 conducts the ignition transistor 6 also conducts and a large voltage is induced at the secondary winding 72 of the ignition coil 7.

Title: Process for obtaining anhydrous fluorides
IPC: C01B9/08
Filed: 1957-06-04
Abstract: Hydrated metal fluorides are dehydrated by heating sufficiently slowly in the presence of gaseous hydrogen fluoride to avoid formation of oxyfluorides by hydrolysis.  Fluorides of uranium (tetrafluoride), thorium, beryllium, zinc, lanthanum and actinium and the double fluoride of zirconium are referred to.  The hydrogen fluoride may be diluted with a gas such as hydrogen, nitrogen, helium, neon or argon which is inert to the metal fluoride, hydrogen fluoride and the materials of which the reactor is constructed.  The hydrated fluoride is preferably introduced at a temperature above the dew-point of the mixture of hydrogen fluoride and water vapour present in the reactor and this temperature maintained.  The portion of the reaction chamber (e.g. a rotary tube or a vibrating trough) adjacent the supply end for the hydrated fluoride is preferably maintained at 150-250 DEG  C. and the other end at 350-500 DEG  C. The hydrogen fluoride and hydrated fluoride are preferably caused to flow in counter-current.  The withdrawn vapours are preferably condensed to form aqueous hydrogen fluoride which is re-used to produce more hydrated fluoride.  The reactor or parts thereof may be constructed of or lined with magnesium, aluminium or alloys containing these metals, or lined with graphite or calcium fluoride.
