Patent GB-713896-A (GB)
Title: Process and apparatus for the production of finely divided metallic oxides and silica
IPC: C01B33/18
Filed: 1952-05-26
Abstract: <PICT:0713896/III/1> <PICT:0713896/III/2> <PICT:0713896/III/3> A pigmentary metallic oxide (e.g. titanium dioxide or alumina) or silica is produced from a reaction mixture of an oxidizable anhydrous halide which may be volatilized below 500 DEG  C. and free oxygen-containing gases, with the aid of auxiliary flames.  The mixture is continuously supplied to a reaction zone in the form of at least one plurality of individual gas streams grouped in a pattern defining a closed figure and contacted with said auxiliary flames formed continuously both inside and outside this figure, and intercommunicating between said individual streams.  All the introduced gases flow in approximately the same direction.  A number of burners and processes using the same are described, in which are employed a plurality of approximately parallel feeding conduits having a plurality of exit openings including an outermost opening for at least a part of one of the auxiliary gases, at least one plurality of exit openings for the reaction mixture, spaced apart and grouped in a pattern defining a closed figure, and at least one exit opening for the other auxiliary gas. The outermost conduit may be provided with a jacket for fluid coolant.  In the cross section of a burner shown in Fig. 2, the outermost opening 4 provides part of the oxygen O in an annular stream while the other part is introduced through the tube 1.  The plurality of tubes 2 provides the reaction mixture R the streams of which are surrounded on all sides by the second auxiliary gas CO (carbon monoxide is a suitable gas) provided from the opening 3.  The tubes are not necessarily circular in cross section.  By the use of the burner of Fig. 7, two pluralities of reaction gas stream R are produced, each lying wholly within a stream of auxiliary gas CO, each plurality surrounding and being surrounded by a stream of the other gas O.  The burner shown in Fig. 13 is characterized in that each individual stream of reaction gas R is surrounded by an individual stream of the combustible gas CO by means of concentric outlets 19 and 20.  The distances (d1 and d2, Fig. 2) of the reaction gas streams, lying within one auxiliary gas, from the nearest gas stream of the other auxiliary gas should be about equal and between 1 and 20 mms., preferably 3-12 mm.  The velocities of the gas streams may be correlated to give continuous burning of both combustible auxiliary gas and reaction mixture, and should lie (in the case of titanium tetrachloride, carbon monoxide and oxygen) between 1 and 50 m/sec. for carbon monoxide and oxygen and 0.5 and 10 m/sec. for the reaction gases; the distance of the central part of the titanium tetrachloride-containing gas stream from the nearest peripheral zone of said stream should be between 1mm. and 1cm.  In some examples, mixed oxides are produced.

Title: Improvements in or relating to centrifugal governors
IPC: G05D13/10
Filed: 1955-05-10
Abstract: 769,150. Centrifugal governors. BOSCH GES., R. May 10, 1955 [May 14, 1954], No. 13444/55. Class 57. A centrifugal governor, particularly for speed control of an internal combustion engine having direct fuel injection, comprises two weights 3 responsive to centrifugal force and whose movement displaces a sleeve (not shown) engaged by a lever arm 4 associated with each weight, each lever arm engaging with the surface of an abutment arm 9 whereby movement of the two weights is made interdependent. In this way, the weights are constrained to travel in the same orbit even when gravitational forces are not negligible relatively to the centrifugal forces and a balanced adjusting force is exerted on the governor sleeve. A spring-loaded bolt engages the sleeve which is connected by a system of levers with the control member of a fuel injection pump.

Abstract: 186,956. Miller, D. J. G., and Lloyd, R. A. May 13, 1921. Roller-and-ring mills. -In a mill for grinding or pulverizing slag, cement, rock, &c. and of the type on which one or more rollers supported and revolved on arms or carriers mounted on a revolving snaft are pressed by centrifugal force against a grinding-ring, as described in Specification 117,281, the rollers 3, Figs. 1 and 3, are fixed to vertical spindles 5 carried in bearings 6 capable of moving radially and carried by the revolving pan bottom 1. The bearings 6 are mounted by trunnion supports 6<x> in brackets 7 on the underside of the pan bottom 1. The shafts 5 pass through openings 1<x> in the pan bottom, a sealed joint being formed by a collar 15 of rubber &c. on the shaft working on a plate 16 on the bottom 1 and having inner and outer baffle rings or collars 17, 18. A ring 5<x>, Fig. 5, upon the upper part of the shaft 5 lies over and outside the top of the bearing 6, and a collar 5<xx> at the lower end works on the bottom horizontal edge of the bearing 6. The oil reservoir 8 is placed on the inside of the bearing and the oil passes to the shaft 5 through ports 9 in the wall. Dust is prevented from passing between the stationary ring frame 4 and the pan bottom 1 by means of a ring 21 located in a recess in the bottom 1 overlying a ring 20 on the bottom of the frame 4. An upwardly projecting ring 23 on the table 1 works in an annular hood or channel 24 in the frame 4. Fan-blades 29 fixed on an extension 23<x> of the ring 23 work in the discharge channel 13 which receives the crushed material passing through the screen 28 and carry the material to the discharge spout 13<x>. The adjustable vanes 40 which throw the crushed material against the screen 28 are carried by studs 41 on the bottom 1. The vanes 40 may be spring pressed. In a modification, the the ring 23, Fig. 7, on the bottom 1 extends below as well as above it. The ring is inclined and its lower part extends into a channel 33 inside the wall 12<x> of the channel 13. Any dust reaching the ring passes down holes 34 into the channel 33, whence it is conducted by vanes 35 on the ring 23 to a delivery spout 36. Inclined vanes 37 on the inner wall of the channel 33 keep down any dust that rises above the vanes 35. Fig. 8 shows another arrangement for preventing the escape of dust from the interior of the pan. A rubber collar 15 is fastened by a clampring 15<x> on to the ring 18 round the hole 1<x> and the upper edge of the collar 15 works in contact with the under surface of the roller 3.

[Class 55 (ii)] Industrial combustible gases containing free hydrogen and organic sulphur compounds are passed at a temperature above 100‹ C., and preferably below 200‹ C., over a catalyst prepared by reducing a non-nitrogenous oxygencontaining compound of cobalt or nickel, whereby diolefine hydrocarbons are converted into saturated hydrocarbons and free oxides of nitrogen partly or wholly removed. The catalyst may be formed from a paste of the finely ground oxide, hydroxide, or carbonate made into pellets or granules or deposited on a clay &c. support and heated in the presence of a reducing gas at about 300-550‹ C. The presence of organic sulphur compounds in the reducing gas or gas to be purified results in the conversion of the metal to catalytically active sulphide. The first Provisional Specification describes also the use of titanium, chromium, and iron as catalysts.

[Class 126] In a gas-fired cooking apparatus, a gas ring burner 17 is surrounded by a wall 22 supporting a solid plate 30 on which the cooking vessel rests, conduction of heat from the plate 30 to the cooker top 13 being reduced to a minimum. The upper part 25 of the wall 22 rests on three separated lugs 27 on the cooker top or surround plate 13 and is connected to the lower part by six ribs 28. The plate 30 has a. corrugated lower surface 31 and is formed with vertical webs 32 having shoulders 33 resting on the lower part of the wall 22 so that the combustion products impinge directly on the cooking vessel which should be of larger diameter than the plate 30. The webs 32 divide the combustion space above the burner into compartments corresponding to the number of burner nozzles 18 but terminate short of the burner nozzles and the centre of the burner to facilitate ignition. Liquid spilling over from the cooking vessel is caught by the upper part 25 of the wall 22 and drains into a tray 35. The ribs 28 are formed with small ramps 29 to facilitate sliding of the cooking vessel on to the plate 30. The diameter of the plate 30 of a domestic stove preferably does not exceed 5¢ inches.
