Title: Improvements in or relating to gear shifting or changing mechanism
IPC: F16H61/02
Filed: 1919-08-29
Abstract: 155,878. Stevens, W. C. Aug. 29, 1919. Controlling variable-speed gearing.-A threespeed and reversing gear suitable for motor vehicles is operated by the sliding in two directions of two selector bars 1, 2, Figs. 1, 2, and 10, operated by a power-operated manually-controlled energy-storing device, such as a spring 10. A plunger 9 acted on by the spring 10 carries racks 7 engaged by sectors 3, 4 upon levers 5, 6, which carry pairs of spring pawls 36, 38, and 41, 42, respectively. The rod 2 carries pawl-engaging snugs 26, 27, and a medial lug 28. The rod 1 has similar snugs 31, 32, and a similar medial lug 33. When power is applied to compress the spring 10 by energizing a coil 15, the heel of a lever 5 or 6 engages the lug 28 or 33 that may have been displaced, and brings the rods 1, 2 to the neutral position shown in Fig. 2. A selector disc 49 is then turned through gearing from a spindle 55 and lever 56, Fig. 10, so as to cause one of the pawls such as 42 to be thrust towards, say, the bar 1 opposite the snug 32. On releasing the spring 10, the levers 5, 6 fly apart, the former idly, the latter carrying with it the rod 1, so as to bring into operation a speed in a gear-box 86, Fig. 10. A switch for energizing the coil, and tripping-gear for releasing the spring arranged at right-angles to the plunger 9 are shown in Fig. 4. The switch comprises a mushroom-shaped contact 67 upon a reciprocal rod 69 normally held out of action away from an insulated funnelshaped stationary contact 66 by a spring 74. A rod 77 connected to the main clutch operating- lever 88 carries a spring latch 76 adapted to engage a hook 75 on the rod 69, a spring 81 on a guide rod 80 normally tending to effect this engagement. To change speed, the selector disc is set and the lever 88 operated. The rod 77 moves to the left, closing the switch. The plunger 9 rises, disengaging the previous speed, until a lip 84, Fig. 4, on the plunger strikes a pin 83 on the latch 76, and allows the switch 67 to open. The plunger descends automatically to bring in the speed selected. An arrangement in which the coil is replaced by the power of the engine is described.

IPC: C09B5/50
Filed: 1922-08-04
Abstract: A blue vat-dyestuff, distinguished by its fastness to chlorine and hypochlorites from the known commercial product made by alkali fusion of b -aminoanthraquinone, is obtained by the following alternative modifications:-(1) b -Aminoanthraquinone which has been freed from such impurities as yield products not fast to chlorine is subjected to alkali fusion; such b -aminoanthraquinone is obtained by dissolving the commercial article in concentrated sulphuric acid and diluting with water or weaker acid so as to precipitate b -aminoanthraquinone sulphate but not the impurities, the sulphate being then decomposed by water.  (2) The alkali fusion is prolonged for 5 hours or more to destroy the portions not fast to chlorine; oxidizing-agents may be added.  (3) The known commercial dyestuff may be treated to remove those constituents not fast to chlorine by solution in concentrated sulphuric acid and dilution with weaker acid so as to precipitate the dyestuff but not the impurities.  This last method may also be applied to the dyestuff which has already been obtained by either of the previous methods.  The products may be further purified by means of hydrosulphite as described in Specification 22762/01.  Examples of the various methods are given. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following:-Crude b -aminoanthraquinone may be purified by extracting the impurities with less concentrated acid; the alkali fusion may be effected at higher temperatures than usual; water may be used for diluting the solution of the dye in concentrated sulphuric acid.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specifications 9269/14 and 9975/14.

IPC: D06C29/00
Filed: 1964-05-26
Abstract: A keratinous fibre containing fabric is lustred by calendering it and subjecting it to a full-decatising operation.  The calendering may be carried out at 100 DEG -350 DEG F with a pressure of 1/2 -2 tons per linear inch and full decatising may be carried out using a steam interval of 1-10 minutes at autoclave pressures of 1-100 p.s.i. gauge and a vacuum interval of 2-60 minutes.  Prior to calendering the fabric may be treated with a reducing agent capable of splitting the systine linkages of keratinous fibres, calendered under conditions insufficient permanently to set a substantial portion of the treated fibres and then subjected to full-decatising to set the remainder of the fibres.  The reducing agent which may be applied as an aqueous solution by spraying, padding, squeezing, immersion or wetting with blankets saturated with the solution, may be an alkanolamine sulphite containing up to 8 carbon atoms in the alkyl chain, zinc or sodium formaldehyde sulphoxylate, sodium or potassium borohydride, bisulphite, sulphite, metabisulphite or hydrosulphide, ammonium bisulphite, sodium sulphide, hypophosphite, thiosulphate, or dithionate, titanous chloride, sulphurous acid, thioglycollic acid, sodium, potassium or ammonium thioglycolate, hydrogen sulphide, ethyl or butyl mercaptan, b -mercapto ethanol or a mixture thereof.  The reducing agent may be used in conjunction with a swelling agent, e.g. urea, guanidine hydrochloride, formamide, N, N-dimethyl formamide, acetamide, thiourea, phenol or lithium chloride, bromide or iodide, or a low molecular weight polyhydroxy compound having a molecular weight no greater than 4,000, e.g. glycols having terminal hydroxy groups separated by 2-10 methylene groups, 1,2 propylene glycol, dipropylene glycol, 1,3-butylene glycol, diethylene glycol, polyethylene glycol, polypropylene glycol, glycerine, diethylglycerol, trimethylolethane, trimethylol butane and tris-hydroxymethylamine methane.  After treatment with the reducing agent the fabric may be dried, subjected to a mild semi-decatising operation comprising 5 seconds of steaming followed by 2 minutes of vacuuming, calendered and subjected to full-decatising.  Fabrics comprising sheepwool, lambwool, mohair, camelhair, alpaca, cashmere, vicuna, llama or angora wool alone or in admixture with other fibres e.g. polyester fibres, may be treated.
