Title: Improvements in or relating to the treating of ores
Inventor: CHERDRON EGON
IPC: C22B34/12
Filed: 1960-03-09
Abstract: In a process for the recovery of titanium from titanium ores containing iron to yield substantially all the titanium as a solution of titanium tetrachloride, the ore is reacted with aqueous hydrochloric acid containing at least 32% by weight of HCl at a temperature of at least 90 DEG C. for not more than 2 hours, the reactants being vigorously agitated throughout, e.g. by tumbling. The temperature should not be above 100 DEG C. to prevent the formation by hydrolysis of insoluble titanium dioxide, but phosphorus pentoxide, phosphoric acid or a salt thereof may be added which permits operation at temperatures up to 140 DEG C.  The solution is separated from insoluble residue, and the iron chloride in solution thermally decomposed to iron oxide and hydrochloric acid recovered. In examples ilmenite is decomposed with hydrochloric acid solution, with and without added phosphorus pentoxide.

Title: A method for continuous deaeration of a concentrated aqueous solution the solute of which consists solely or mainly of polyvinyl alcohol
IPC: C08F6/06
Filed: 1963-03-05
Abstract: In a method for the deaeration of concentrated aqueous solutions the solute of which consists solely or mainly of polyvinyl alcohol, the solution is contacted with steam.  Other materials which may be present in the solutions include organic and inorganic acids, inorganic salts, surface active agents, antioxidants, pigments and dyes, and the solutions may be spun or moulded into slivers, films, fibres and the like by dry or semi-fusion processes.  The solution may be continuously fed to and removed from a deaeration chamber having a steam atmosphere. The solution may be fed to or passed through the chamber in the form of jets or filaments, or as a thin film.  The chamber may be steam-jacked.  By supplying to the chamber superheated or supersaturated steam the solution may be concentrated or diluted respectively simultaneously with deaeration.  A body of the solution may be maintained in the bottom of the chamber and stirred either mechanically or by passing at least a portion of the steam therethrough.  Apparatus suitable for carrying out the method of the invention is described and illustrated and the use of such apparatus is described in examples.

Title: Improvements in and relating to windscreen-wiper driving mechanisms
IPC: B60S1/12
Filed: 1941-07-10
Abstract: 551,337. Converting rotary into oscillating motion; windscreen wipers. ACROTORQUE CO. July 10, 1941, No. 8756 and 8757. Convention dates, Feb. 18 and April 2. [Class 80 (i)] [Also in Groups XXIII and XXVI] The actuating mechanism of a windscreen wiper, particularly for use on aircraft, is adapted to drive a pump for supplying a de-icing liquid such as alcohol to the windscreen. A constantly rotated shaft 18 has a cross-groove endless track 19 which, through a pin 20, reciprocates a sleeve 17 having on its flat upper surface rack teeth 16 which oscillate a pinion 15 on a shaft 11 carrying the wiper arm. The shaft 18 is driven by a liquid motor 23 of the crescent-chamber type the rotor 21 having a number of blades forced outwardly by springs. The oil for driving this motor may be utilized to lubricate the gearing by allowing some of it to pass through a duct 49. The driving shaft 18 also serves to actuate a pump 31 for delivering the alcohol to the windscreen. The pump, also of the crescent-chamber type has a rotor 28 with spring-pressed blades 30, Fig. 5, urged against the bore 29 provided with inlet and outlet passages 32, 33. The alcohol is delivered through passages 33, 35 .. 37 to a bore 34 in the shaft 11 whence it is conducted to the wiper arm. In order that the pump may be used only when required, it is driven through a clutch 40, 41 actuated by a knob 44 on a screwed spindle 43, and a ball 45. The member 40 of the clutch forms part of a sleeve 38 a pin 39 on which engages a slot in the driving shaft. The member 41 forms part of the pump rotor 28. A spring washer 46 tends to urge the member 40 into engagement. A stop 47 prevents over-stressing of the spring. To prevent the two liquids from intermingling packing 50 of an expanding type is employed for the sleeve 38 and a similar packing for the shaft 11. Each of these packings has a groove such as 52 to collect any escaping liquid and conduct it to an outlet. The Specification as open to inspection under Sect. 91 describes a mechanism of simpler form, the motor and pump being dispensed with, and the shaft 18 driven by a flexible shaft. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to flexible couplings, dampers and the like
IPC: F16D3/68
Filed: 1947-04-01
Abstract: 641,425. Resilient drives. CROSET, L. P. April 1, 1947, No. 8766. [Class 80(ii)] [Also in Group XXXII] In resilient drives or mountings of the kind having initially compressed natural or synthetic rubber blocks 7, Fig. 2, interposed between blades 5, 6 on the driving (or driven) member 3 and the concentric driven (or driving) member 4, the blocks have limited freedom to expand axially and/or radially under load to fill the cells formed by the members 3, 4, blades 5, 6 and closure end plates 8a, 10, Fig. 3, and are so designed that when those blocks transmitting torque fill their cells, the idle blocks are still under compression. As shown, applied to a flexible coupling, two axially-tapered blocks 7 are inserted between each co-acting pair of the blades, which have a corresponding double axial taper. The blocks are held in position by the plates 10, 8a the latter of which is bolted to a driven hub 8b. Under sufficient load, the blocks expand to fill the spaces 14 between them. In Fig. 1, (not shown) the blades 5, 6 are flat and one or more non- axially-tapered blocks are inserted between each co-acting pair, whilst one closure end plate is itself formed as a driven hub. Where a single block is used, initial axial play is provided between the ends of the block and the side flanges and, additionally or alternatively, initial radial play is allowed. The blocks 5, 6 may be cast integral with or welded to the members 3, 4. As applied to flexible gear mountings, the member 4 is formed as a toothed rim and the flanges 8a. 10 rotatably engage a hub member 3 closely. The blocks 7 preferably have an axial length of from one and a quarter times to twice their radial dimension, and have an initial compression of from 5 to 10 per cent of their peripheral width and a similar but slightly smaller further compression when they fill their cells under load. According to the Provisional Specification, the blocks may be hollow or apertured to obtain non-linear compression characteristics and/or to improve cooling, and may have arcuate flanks. Further, where the members 3, 4 are independently supported the drive is preferably unlubricated; but the member 4 may be supported and centred on the edges of the blades 5 with or without additional bearing engagement between the inner edges of the blades 6 and the member 3, when lubrication is preferably employed.
