Title: Improved process for obtaining iron from ores
IPC: C21B13/00
Filed: 1928-05-29
Abstract: 297,096. Vereinigte Stahlwerke Akt.- Ges. Sept. 16, 1927, [Convention date]. Ferric chloride. - Ores containing iron are treated with chlorine or hydrochloric acid in a state of vapour, so that ferric chloride is volatilized and then reduced to metallic iron, by suitable means, for example, by means of hydrogen. The chlorination process is improved by carrying out the process under increased pressure, preferably about 10 atmospheres. The reaction speed is increased by altering the pressure several times during the chlorination, even sufficiently to produce a partial vacuum. This is stated to assist the expulsion of the reaction product from the ore and bring fresh gases to attack the ore.

Title: Process for treating the residual gases in the manufacture of titanium tetrachloride
Inventor: WHYTE JOHN FREDERICK
IPC: C01G23/02
Filed: 1956-05-18
Abstract: Hydrochloric acid of at least 20% by weight strength is recovered from the residual gaseous mixture resulting from the manufacture of titanium tetrachloride by chlorinating a titanium bearing material in the presence of the reducing agent and p  separating the solid chloride product.  Such a residual gaseous mixture, consisting mainly of carbon monoxide and dioxide, hydrogen chloride and small amounts of silicon and titanium tetrachloride is contacted with an organic liquid in which hydrogen chloride is insoluble or sparingly soluble and in which the said tetrachlorides are soluble and the resulting gaseous mixture is thereafter treated with a limited quantity of water to produce the hydrochloric acid solution.  Clogging of the washing towers by hydrolysis of silicon and titanium tetrachloride contaminates is thereby avoided.  The organic liquid is preferably a liquid paraffin hydrocarbon, such as n-heptane, or halogenated hydrocarbon, such as carbon tetrachloride, chloroform, trichlorethylene, chlorinated diphenyls, and in particular o-dichlorobenzene.  The absorption of the tetrachloride is preferably effected at atmospheric pressures at temperatures from -40 to 70 DEG C. and the gas and absorbent liquid preferably flow in countercurrent down a packed tower.  Silicon and titanium tetrachloride adsorbed may be recovered by distillation or alternatively they may be subjected to hydrolysis and converted to insoluble products which are filtered off.

Abstract: 317,154. Chester, F. R. May 29, 1928. Table games.-An apparatus for playing a game which may simulate golf comprises a deck with a cabinet, the deck having a number of openings and being provided with a turntable operable from outside the cabinet. A dummy figure is mounted on the turntable and has associated with it an element for impelling a ball towards any one of the openings, this element also being actuated from outside the cabinet. Raised portions resembling bunkers and a depressed portion constituting a hazard are formed on the deck, which is everywhere sloped so as to ensure the return of a driven ball which has failed to enter a hole to the impelling member. The turntable 17, Figs. 2 and 3, is rotated by a lever 25 connected bv a link 24 to an arm 23 fixed to the turntable. The upper part 18 of the figure is rotatable, and is connected to a shaft 29 to which is attached a pinion 31 engaging a rack 32. This rack is connected by a link 33 to a crank actuated by a handle 35. Balls passing through any of the holes in the deck are caught by a pan 87 and gravitate to a shoot 38 connected with a shafting 39, Fig. 7, which terminates in an opening 41 in the deck 16, and in which moves a plunger 40. A shaft 45 may be turned through 45‹ by a handle 49, and when this occurs the plunger is moved to the top of the shaftway by an arm 42. The operation of a coin-freed mechanism 48 of a well-known type allows the shaft to be rotated through a further 45‹ upon the insertion of a coin, a gate 57 then being raised and a number of balls 27 rolling down the shoot to such a position that they may each in turn be elevated to the platform by repeatedly turning the shaft 45 through its initial movement of 45‹. In a modification two balls are raised simultaneously to the level of the platform, but only one is discharged thereon at each movement of the plunger. The object of the game is to drive balls into the scoring holes 78. Unsuccessfully driven balls either return to the turntable or fall through holes 80 in the hazard portion. A ramp 83, is provided and also a tunnel 81 whereby balls may return from the green 76 to the turntable. Reference has been directed by the Comptroller to Specification 292,092.

Mixed resin compositions comprise (a) 5-45 wt. per cent of a siloxy-terminated polybutadiene as above, and (b) 55-95 wt. per cent of a hydroxyl-functional organosilicon resin consisting essentially of units of the formula  wherein: R<SP>1</SP> is a C 1-6  monovalent hydrocarbon radical, at least 70 mol. per cent of the R<SP>1</SP> radicals being methyl and phenyl, c has an average value of 1À0 to 1À7, and the organosilicon resin has a silicon-bonded hydroxyl content of 1-10 wt. per cent based on the weight of the resin. The two components couple together in the presence of a suitable solvent, e.g. toluene or xylene, either without or with a suitable catalyst, e.g. an amine or titanate. The mixed resins may be cured by the presence of either or both of (i) a silanol condensation catalyst, particularly ferric octoate, and (ii) an organic peroxide cyclizing agent, e.g., 2,5-dimethyl - 2,5 - bis - (t - butylperoxy)hexane. The compositions may contain other polysiloxanes, e.g. a phenylmethylpolysiloxane to provide coatings with release properties. Fillers, e.g. silica, and pigments, e.g. a mixture of titania and alumina, may also be present. Compositions containing 10-30% of (a) are suitable for coating metals, e.g. pipes, and examples relate to the coating of sheets of aluminium and steel.

Abstract: 509,082. Liquid - pressure remote - control systems; aircraft alighting-gear. AUTOMOTIVE PRODUCTS CO., Ltd., and PARKER, S. M. May 31, 1938, No. 16259. [Class 69 (ii)] [Also in Group XXXIII] A double-acting liquid-pressure remote-control system having means for retarding the flow of return liquid from a slave unit, the retarding means being adjustable so that its setting varies for different positions of the controlled member, is characterised by the fact that the flowretarding means comprises a valve which is urged on to its seating in opposition to the flow of return liquid by a coiled compression spring, the opposite end of said spring being engaged by an abutment the position of which changes during the operation of the slave unit so as to vary the closing force exerted by the spring, the said valve being by-passed by a non-return valve acting in the opposite sense. The backpressure valve unit 19 comprises a spring-loaded check valve 30 allowing substantially free flow from the distributing valve 13 to one end of the jack 17, and a check valve 34 adapted to restrict flow from the said end of the jack to the distributing valve, the valve 34 being loaded by a spring 35 the end of which bears against a member 40, acted on through a member 41 by an adjustable screw 48 carried by one arm of a bell-crank, the other arm 44 of which carries a roller 49 whereby the spring loading of the valve is varied according to movement of the jack. As applied to a retractable undercarriage on an aircraft, the roller 49 is contacted by a cam carried by a pivotally mounted part of the undercarriage, the cam being shaped to correspond with the varying external forces acting on the undercarriage during its lowering movement. Alternatively, the spring-loading may be varied only at the end of the stroke of the actuated member so as to bring the latter to rest without shock. By removal of a pin 42 the bell-crank may be rendered ineffective to vary the spring loading, and the spring 35 slightly relieved.
