Title: Improvement in methods of obtaining zirconium compounds
IPC: C01G25/00
Filed: 1927-05-23
Abstract: 271,873. Titanium Alloy Manufacturing Co., (Assignees of Kinzie, C. J.). May 27, 1926, [Convention date]. Zirconium oxide; zirconium carbonate; double zirconium potassium sulphate, oxalate.-Silicious zirconium ores are decomposed to bring the zirconium and silicon into acid solution, from which the zirconium compounds alone are precipitated and separated. The finely milled ore is fused with a limited amount of alkali e.g. sodium carbonate or caustic potash at about 950‹ C. and after disintegration with water to form a slurry is dissolved in dilute sulphuric or oxalic acid. On cooling to between 70‹ C. and 40‹ C. or adding a potassium compound e.g. potassium chloride to the acid solution, double zirconium potassium sulphate or oxalate separates, leaving silicon, titanium and iron compounds in solution. After calcining the double salt and driving off sulphur trioxide, the potassium sulphate is removed with water and zirconium oxide left. The double sulphate may be precipitated from the solution by neutralizing about 15-25 per cent of sulphuric acid with sodium carbonate, and purified by dissolving the salt in warm water, filtering, and recovering the zirconium from solution e.g. by adding sodium carbonate to slight alkalinity and heating to decompose any zirconium carbonate formed.

IPC: H02K17/30
Filed: 1930-05-06
Abstract: 344,286. Master control of A.C. motors; controllers. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Cutler- Hammer Manufacturing Co.; Milwaukee, Wisconsin, U.S.A.) May 6, 1930, No. 13888. [Class 38 (iii).] Actuating electromagnetically.- The motor M driving a printing press has its speed predetermined by a rheostat R, and the time between closure of starting and running contactors 3, 4 is determined b y the adjustment of the rheostat. Closure of start push-button 6 causes closure of main switch 2 and starting contactor 3. Switch 2 in closing strains a spring connecting it to a dashpot controlled contact 9, which thus approaches a .contact 10. Engagement of contacts 9, 10 causes closure of running contactor 4 to bring the rheostat R into operation, and starting contactor 3 thereupon opens. The delay before contacts 9, 10 engage is varied according to the setting of the rheostat R, by positioning contact 10 according to this setting.

Title: Improvements relating to railway vehicle braking apparatus
IPC: B60T13/66
Filed: 1958-05-09
Abstract: 881,263. Fluid pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd., SIMMONS, A. W., and DARWALL, M. T. D. March 26, 1959 [May 1, 1958], No. 13899/58. Class 103 (1). An electro-pneumatic braking apparatus for railway vehicles, comprises a brake controlling device having a mercury tube retardation controller with two contacts for operating the holding valve in addition to the normal holding and application valve contacts. In the release position of the device, the contacts of drum contactor DC are open to maintain relays RA, RH and wires WA, WH de-energized to keep the holding and application valves open. The mercury tube T, has contacts CA, CH for the application and holding valves, a contact CS connected to battery B, a blow-down pressure limiting valve contact CB and a holding-make contact CHM. Should a brake application be initiated pneumatically and independently of the driver's control, then brake, pressure would normally increase up to the value at which the limiting valve opens; but at a rate of retardation corresponding to a brake pressure lower than that at which the limiting valve means open, the mercury body M moves to engage contact CHM to pick up relay RB and energize relay RH and wire WH to close the holding valve and prevent pressure release via the limiting valve. Should the rate of retardation exceed a predetermined value, the mercury body M will be moved from contact CB to deenergize relay RH and wire WH to open the holding valve to dissipate pressure via the limiting valve and holding valve until retardation is such that contact CB is again immersed. The contact CH is closer its co-operating free surface of body M than the contact CHM so that on clockwise rotation of the tube by adjustment of the controlling device, the contact CHM is farther from its free surface then is contact CH, and cannot therefore interfere with the proper operation of contacts CA, CH when energized in the brake application zone and it is not necessary for the connection between CHM and relay RB to be broken. Specification 875,588 is referred to.

Patent GB-794179-A (GB)
Title: Dyeing textile materials
IPC: D06P1/00
Filed: 1955-05-16
Abstract: The wash-fastness of colourations produced on textile materials by means of a disperse acetate dyestuff containing a plurality of reactive groups selected from amino and alcoholic and phenolic hydroxyl groups is improved by treating the dyed material with formaldehyde together with a soluble, heat-curable, condensation product of formaldehyde and a compound containing a reactive -NH- group, the condensation product containing N-hydroxymethyl or N-lower-alkoxymethyl radicals or both, and heating to effect reaction between the dye and the condensation product, if desired in the presence of an acid catalyst.  The process is applicable to fibres of cellulose esters or ethers (including cellulose triacetate) if desired in admixture with other fibres, many of which are specified, and also to nylon fibres.  Condensation products of formaldehyde with urea, melamine, ethylene urea, guanidine, dicyandiamide, guanyl urea or N-methyl urea may be employed and the methylol groups may be etherified with lower aliphatic alcohols, the condensation product being applied as an aqueous solution, containing, if desired, a swelling agent for the fibre.  Many suitable disperse acetate dyestuffs, including those described in Specifications 794,176, 794,177 and 794,178 are specified.  In the case of chelatable disperse acetate dyestuffs, improved results are obtained by applying a metal-containing chelating agent to the dyed material before, together with or after the condensation product, specified chelating agents being copper sulphate or acetate, copper complexes with organic compounds and chelating agents containing zirconium, nickel and chromium.  In treating textiles comprising mixtures of cellulose acetate and regenerated cellulose fibres, silicones and condensation products of long chain fatty amines or amides with melamine and formaldehyde may be applied to the textile together with the condensation product.  Such textiles may also be dyed in a bath containing a direct dyestuff in addition to the disperse acetate dyestuff, and a subsequent treatment with a copper-containing chelating agent also serves to fix the direct dyestuff.

Title: Electrically driven can opener
IPC: B67B7/70
Filed: 1973-06-26
Abstract: 1432930 Electric powered can openers ETUO 26 June 1973 [3 Jan 1973] 14505/75 Heading B8D In an electrically-driven can opener, which comprises can-positioning stops 63, 72 and 82, a driven traction wheel 67, a pivoted lever 79 operative to actuate a drive-initiating contact 104 and to swing a cutter 80 into a can-piercing position, and a spring 81 adapted to press a can rim against the traction wheel, the lever, cutter and spring are all pivoted about a bolt 77 and the cutter has a degree of angular lost motion relative to the lever and is of such a form that the can-cutting reaction tends to urge the cutter from the can-piercing position into a can-cutting position against a stop 84, the resultant relative angular movement of the cutter pressing the spring against the cam rim independently of the lever. The lever has a step 100 which engages the cutter to move the latter into a can-piercing position, and the cutter has a notch 98, the upper end of which presses the spring against the can rim during the reactive movement of the cutter from the piercing position to the cutting position independently of lever movement. Due to the degree of clearance of the spring within the notch, the spring may be pressed with greater pressure against the can rim by a lever stop 103 on further depression of the lever to correct any traction wheel slippage. In order to facilitate the passage of a dented or seamed portion of a can between the wheel or cutter, the traction wheel is carried on shaft 66, which is capable of limited axial movement in a direction away from cutter against the bias of springs 74 and 75, which also resist axial movement of the similarly-displaceable can abutment 72, Fig. 8 (not shown). The plate 60, traction wheel, lever and cutter may be removed as one assembly on release of plate latches 61 and 62 and disengagement of dogs 71 on the shaft 66 from the bore of a drive hub, Fig. 4-6 (not shown). The blade 89 of the cutter, Figs. 7-11 (not shown), is tapered rearwardly from a bevelled forward cutting edge 93A to reduce the blade thickness towards the trailing edge and hence avoid binding of blade. The tip 94 of the blade is bent over to form an initially pierced opening which is enlarged with respect to the cut formed by the blade to ensure complete separation of the severed can lid. A lid-retaining magnet 83, Fig.2 (not shown), is carried on the can abutment pin 82.
