Title: Improvements in the manufacture and production of dyestuffs
IPC: C09B43/00
Filed: 1929-07-22
Abstract: 338,930. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 22, 1929. Dyestuffs for colouring chrome leather are made by warming aromatic N-nitroso compounds with aromatic amino-, hydroxy-, or aminohydroxy compounds. Since the components react at the temperatures used in dyeing chrome leather the dyestuffs may be produced in the dyebath by dyeing with a mixture of the compounds. In examples (1) the dyestuff sulphanilic acid # a-naphthol is warmed with the nitroso compound of the azo dyestuff sulphanilic acid # diphenylamine; the product gives dark red brown shades on chrome leather, sumac-tanned sheepskin and wool, (2) a mixture of the dyestuff 4-nitraniline- 2-sulphonic acid # a-naphthol and the nitroso compound of the dyestuff sulphonated naphthylamine (containing 2 : 5- and 2 : 8-naphthylamine sulpho acids) # diphenylamine gives fawn dyeings on chrome leather, (3) a mixture of 4- aminoazobenzene-3 : 4'-disulphonic acid-azo-anaphthol with the nitroso compound of the dyestuff sulphanilic acid # diphenylamine gives Bordeaux dyeings, (4) a mixture of the dyestuff sulphanilic acid # a-naphthylamine and the nitroso compound of the dyestuff 4-chloraniline- 3-sulphonic acid # diphenylamine gives a dark brown, (5) the dyestuff sulphanilic acid # resorcinol mixed with N-nitrosodiphenylamine-psulphonic acid dyes olive brown, (6) the nitroso compound of the azo dyestuff sulphanilic acid # diphenylamine is boiled with J acid in water; the product gives grey dyeings on chrome leather, (7) the mixture in 6 is warmed with sodium carbonate; the product gives brown dyeings, (8) the nitroso compound in 2 is boiled in water with 4-toluidine-2-sulphonic acid, (9) a mixture of the nitroso compound in 1 with #-naphthylamine hydrochloride dyes chrome leather orange, and with (10) a-napthylamine hydrochloride, dark brown, (11) a mixture of the nitroso compound in 4 with 1-amino-8-naphthol-4-sulpho acid dyes brownish-grey, (12) the nitroso compound in 1 mixed with 2-amino-3-naphthol-6-sulpho acid dyes dark brown, (13) N-nitrosodiphenylamine-p-sulphonic acid is boiled with 4-toluidine-2-sulphonic acid in acid solution, and (14) mixed with 2 : 8 : 6-acid, (15) 2-methylnitrosoaniline-1-carboxylic acid is mixed with J-acid.

A ferromagnetic steel pipe or pipes is or are heated by currents induced in the inner wall portion thereof, the outer wall portion carrying substantially no current, an insulated conductor line or lines connected to an A.C. supply and extending within the entire length of the pipe(s) inducing said currents, the ends of the pipe(s) being interconnected by a conductor(s) of low impedance. The depth S in which the current flows is given by S = 50 30#e/Áf, and the following conditions are satisfied: t> 2S, D#S, l#D (e is the resistivity, Á the permeability, f the frequency, D the inside diameter, t the thickness, and I the length).

The connector is first slipped through the bores 4 and 11 of the two components, the projections 10 passing through matching grooves 12, Fig. 2, in component 3, and is then turned until the projections 10 engage the second component at the stop 13. A slot or polygonal recess 8 in the head of the connector provides for it to be engaged and rotated by a screw driver or by the connecting tenon of a brick from a toy building set. Where the first component is angled, the head may be extended sufficiently to enable it to be turned without the brick touching the free leg of the angle, see Fig. 6. The bore 29 in the head may support a shaft. The head may be provided with a wing-like handle 18, Fig. 5. and the projections accommodated in a recess of the component 3 In another embodiment the second component is a toy brick and the locking part of the connector is guided through a re-entrant groove in the brick (Figs. 3 and 7, not shown) by diametrically opposed recesses in the connector and the fastening is made by turning the connector so that the projections engage the re-entrant groove. It is stated that locking could be achieved with matching threads on the connector and bore 11 of the second component, instead of by means of the projections.

A machine as set forth in the parent Specification and Specification 966,701 is provided with a plate 10 for holding down the toe end portion of the sole in the matrix 4 of carrier 2 before the sole is operated upon. The plate is carried by a spring arm 12 which is secured to an arm 14 in turn carried by a vertical shaft 16. The shaft 16 has a piston 18 movable in a hydraulic cylinder 20 and has secured to the lower end thereof a pinion 30 meshing with tack teeth 44 of a piston 42 movable in an hydraulic cylinder 34. A spring 36 surrounding shaft 16 within the cylinder 20 ensures that the plate 10 is in its raised inoperative position when the machine is not in operation and the hydraulic fluid is not under pressure. In operation, a sole is placed in the matrix and the machine is put in motion. The carrier and matrix are moved by hydraulic means towards and beneath the cutter 6 and at the same time the plate 10 is swung from its out-ofthe way position (shown in dot - and - dash lines in Fig. 1) into a position over the toe end of the sole by means of the tack teeth 44 meshing with the pinion 30. The cutter 6 is then moved down by hydraulic means into a position where it may be engaged by the heel end portion of the sole and at the same time the plate 10 is moved down by means of the piston 18 so as to press the toe end portion of the sole into the matrix before the machine begins to operate on the sole. The carrier continues to move under the cutter and takes the sole along so that the sole passes from beneath the plate 10 into immediate engagement with a plate corresponding to the plate 254 of Specification 966,701 and thence under the cutter. At the end of the operation, the movements are reversed.

Title: Improved method for forming a compressible product

Filed: 1968-05-16
Abstract: 1,219,009. Compressible laminate. W. R. GRACE & CO. 16 May, 1968, No. 23347/68. Heading B5N. [Also in Division F2] A compressible porous laminate comprises a plurality of layers of parallel filaments 21 the filaments of each layer being at an angle to those of the adjacent layer(s), the filaments being joined at their cross-over points by an elastomeric binder material 22 and the filaments defining void spaces 23 in the laminate. The laminate may be in the form of a roll produced by winding on a core or may be a sheet formed by cutting such a roll axially of the core. In one method of making the laminate a filament is coated by passing it through a bath of elastomeric binder or by means of a coated roller, the coating is dried by heated air or infra-red lamps, and the filament is wound on a core where the binder is cured. In a second method uncoated filament is wound on a core and the binder material applied to each wound layer by spraying. More than one filament may be wound at a time. The layers may be wound at different angles. An abrasion resistant coating or layer 20 e.g. of butadiene/ acrylonitrile, or butadiene/acrylonitrile/styrene copolymer, PVC, polyvinylidene chloride, epoxy or polyurethane resin may be applied to the wound filaments in solution or as a latex or as a preformed film or tape or a shrinkable film. The filaments may be of natural or synthetic fibres such as glass, modacrylic, polyester, polyethylene, polypropylene, polyvinylidene chloride, fluorocarbon polymer, rayon, nylon, acrylic, cotton, or wool fibre. The filament may include a plurality of strands. The elastomeric binder may be nitrile rubber, neoprene, natural rubber or butadiene/styrene rubber and is preferably applied in solution, or as an aqueous latex. The binder may include a foaming agent and be foamed after application. When forming the laminate on a core a layer of compressible foam material e.g. neoprene, polyurethane or natural rubber, may be first applied to the core. The core may be of steel, rubber, or plaster, or may be collapsible, or perforated, i.e. in the form of a hollow perforated cylinder. The core may be slid out or dissolved out of the layers of filaments. The wound material may be cut to form a lithographic blanket. Alternatively the filaments may be wound on a tyre rim and coated with a rubber tread compound to form a tyre, or may be removed from the core and inserted in a conventional tyre carcase.
