Title: Calcined borax and process of producing same
IPC: C01B35/12
Filed: 1929-06-14
Abstract: 330,146. American Potash & Chemical Corporation. March 11, 1929, [Convention date]. Drawings to Specification. Calcined borax of a relatively dense nature, for example containing 8-21 per cent water, and having an apparent specific gravity of 0.5 to 0.9, is obtained from hydrated borax by subjecting the latter to the action of heated gases, for example, air, at a temperature below that at which the borax melts or dissolves in its water of crystallisation. The operation may be conducted in stages, that is, the borax may be passed successively through chambers through which a current of air is passing, each chamber having a higher temperature than the preceding, and the air in each having a lower degree of humidity than in the preceding. Thus, through five chambers, the temperature may increase from 50‹ to 325‹ C., and the humidity may decrease from 0.1 pounds of water per pound of air to zero. Or the operation may be conducted in a long chamber, the air and borax being passed in countercurrent, in accordance with the above conditions of temperature and humidity.

Title: Improvements in or relating to circular knitting machines
IPC: D04B15/68
Filed: 1921-07-11
Abstract: 184,031. Wildt & Co., Ltd., and Wildt, E. July 11, 1921. Circular machines. - Automatically-controlled mechanism for producing tuck-work in seamless stockings is arranged so that the tuck-work can be discontinued through the heel, toe, foot, bottom, or other desired parts and continued through other parts of the article, such as the instep, while the mechanism can be put into or out of action as a whole when required. Three kinds of needles are used, namely, ordinary single-butted needles a, single-butted long-latch tucking-needles b, and double-butted long-latch needles c, the tail butts c', c<2> of which are of different lengths. The needles b, c produce tuck-work on the instep and the heel side respectively of the cylinder. In making tuckwork all round the leg, a vertically movable clearing-cam 1 is put into and out of action automatically so as periodically to clear the loops from the needles b, c by acting on the knitting butts x. When tuck-work is to be made on the needles b, while plain fabric is made on the needles c, the cam 1 is retained in the low position and a supplementary clearing-cam is brought into action to clear the tuck loops on the needles c by acting on the tails c<1>, c<2>, the needles b retaining their loops and subsequently producing tuck stitches. The cam 1 is operated by mechanism which includes a pattern device by means of which the number of loops in each tuck stitch and the interval between the tuck stitches can be prearranged. A drum 3 having removable, inter. changeable dogs 4 is intermittently rotated so that the dogs pass under and raise a lever 5 pivoted at 6 and having a rigidly projecting finger 7 provided with a plate 7<a> carrying a. roller 8 which acts against the lower end of a plunger carrying the cam 1. The plate is clamped on the finger 7 and fastened by a screw 7b which allows the position of the roller 8 and the height to which the cam 1 is raised to be adjusted. The drum is racked on by a pawl 9 acting on ratchet teeth 11, back-lash being prevented by a spring washer 14 acting on a fibre washer &c. 15. When tucking is to cease, the cam 1 is lifted to the clearing position by a finger 16 on a rocker 17 actuated through connections 23, 22 by a cam 18 on a pattern drum 19. Another finger 20 on the rocker 17 holds the oscillating member 10 carrying the pawl 9 out of action, thus stopping the drum 3. The supplementary clearing cam is moved radially through connections 27, 28 and 26 by stepped cams as 25 on the drum 19. The stepped configuration of the cams 25 allows the supplementary clearing cam to assume two positions in which it engages either all the tail butts c<1>, c<2> or the long butts c<2> alone, a variety of tuckwork effects being thus obtainable.

Patent GB-867783-A (GB)
Title: Improved liquid reflective coating compositions
IPC: C09D167/08
Filed: 1957-06-14
Abstract: Reflective coating compositions comprise high refractive index transparent glass microspheres and aluminium pigment paste dispersed in the following compositions: (a) nitrocellulose wet with ethanol, oil-modified alkyd resin, dibutyl phthalate, butyl lactate, xylol, and butanol; (b) as (a) with the addition of an organic derivative of bentonite made into a paste with ethylene glycol monoethyl ether; (c) polyamide-modified alkyd resin, naphtha, mineral spirits, a metal naphthenate drier, and butyraldoxime as an antiskinning agent; (d) phenol-aldehyde resin, coumarone resin, neoprene rubber milled with zinc oxide, magnesium oxide, sodium acetate, an antioxidant, ethanol, toluene and butyl lactate.ALSO:A reflective coating composition comprises a mixture of varnish solution, finely divided metal flake reflective pigment, and transparent glass microspheres having a refractive index of at least 1.8, the pigment particles being of substantially smaller size than the microspheres.  During drying of the composition, movement of the metal pigment particles occurs, so that the front surfaces of the glass microspheres become optically exposed, and the pigment particles become contiguous to the back surfaces.  The glass microspheres preferably have a diameter of from 25 to 75 microns, and are present in a volume concentration of 50 to 85%. If the paint is to be viewed under dry conditions, the optimum value of the refractive index of the microspheres is about 1.9; if wet with water, about 2.5; and if covered with a transparent varnish, coloured or clear, to provide a flat outer surface, about 2.8.  The effective refractive index of the microspheres may be increased by providing them with a concentric transparent coating of lower refractive index.  Mixtures of microspheres of differing refractive indices may be used.  The metal pigment may be aluminium, bronze powder, copper, tin, German silver or nickel flake, or gold or silver leaf.  A colloidal suspending agent, e.g. an organic derivative of bentonite, may also be present.  The varnish may be an oil or spirit resin varnish or a lacquer.  In examples, the varnishes used comprise nitrocellulose and an oil-modified alkyd resin, or a polyamide modified alkyd resin, or a phenolic resin, cumarone resin and neoprene rubber mix. Specifications 556,935 and 641,547 are referred to.

Title: Improvements in or relating to the production of a novel chlorine-containing derivative of dihydropyran
IPC: C07D309/10
Filed: 1943-11-19
Abstract: 2-Hydroxy-3-chlorotetrahydropyran is produced by reaction of dihydropyran (dihydro-g -pyran) with aqueous hypochlorous acid, which may be obtained by treating chlorine water with mercuric oxide by acidifying sodium or calcium hypochlorite solutions or by dissolving in water a compound such as chloramine T liberating hypochlorous acid, but is preferably generated in situ by passing chlorine into an aqueous emulsion of the dihydropyran, advantageously at 0-5 DEG  C. and optionally in presence of a dispersing agent.  The water-soluble product may be isolated by extraction with a solvent substantially immiscible with water, e.g. ether, benzene, chloroform, methylene chloride or ethyl acetate.  In examples: (1) chlorine is passed slowly into an aqueous emulsion of dihydropyran until the dihydropyran phase has disappeared and the product is isolated by extraction with ether; (2) chlorine is passed into an aqueous emulsion of dihydropyran maintained at 0-5 DEG  C. until the dihydropyran phase has disappeared, the liquor being then neutralized with soda ash and extracted with ether and the product purified by distillation in vacuo.

Abstract: 477,467. Indiarubber. FIRESTONE TYRE & RUBBER CO., Ltd. July 13, 1936, No. 19424. Convention date, July 13, 1935. [Class 70] Rubber articles such as motor vehicle fenders are made by mounting the article in unvulcanized condition upon a surface convex in planes substantially at right-angles to each other, applying tension to the article at two points, so that the article lies in contact with the surface between the tensioning points, and vulcanizing, so that, under the influence of gravity, the unsupported portion of the article conforms to the curvature transverse to the plane of tension. In making rubber fenders, a rubber strip is put on a form 10, stretched longitudinally, and held by adjustable clamps 15. The arcuate form 10 is also transversely arcuate along one edge, and in tensioning the strip longitudinally it is drawn down towards the transverse arc. The work is then vulcanized, and, during the initial phase of vulcanization, the rubber softens, and moves down to rest on the transversely arcuate portion of the form, in which position it is fully vulcanized. During vulcanization several workcarrying forms are placed in an inclined position on a trolley.
