Title: Improvements in incorporation of lignin into synthetic rubber
IPC: C08L21/00
Filed: 1955-05-31
Abstract: Compositions containing 25 to 75 parts of lignin per 100 parts of synthetic rubber are prepared by mixing a latex containing 25 to 75 per cent of the rubber with an aqueous alkali solution of the lignin, coagulating with an aqueous solution of an acid, e.g. formic, acetic sulphuric, hydrochloric or phosphoric acid, which may contain added salts, adding the remainder of the rubber latex and completing the coagulation by residual or added acid.  The rubber may be an alkaline emulsion polymer of one or more of butadiene-1,3, isoprene, chloroprene, piperylene and 2,3-dimethyl butadiene-1,3 with optionally one or more of styrene, a -methyl styrene, parachlorostyrene, dichlorostyrene, vinyl naphthalene, acrylic acid, methyl acrylate or methacrylate, acrylonitrile, methacrylonitrile, methacrylamide, methyl vinyl ketone, methyl vinyl ether and vinylidene chloride.  Carbon black, zinc oxide, sulphure, mercapto benzothiazole, copper diethyl dithiocarbamate, stearic acid, clays, plasticizers, tackifiers, resins and aromatic, naphthenic, paraffinic or asphaltic rubber processing oils may be added before, during or after coagulation.  The first coagulation is preferably carried out by high-speed agitation with excess acid which is neutralized by alkali, e.g. sodium hydroxide, the slurry blended with the remaining latex and the second coagulation effected by adding acid with lowspeed agitation.  After filtering and drying the product is milled to give a uniform lignin dispersion.  Specification 633,725 is referred to.

In the arrangement shown the heating means consists of a water jacket 5 around the tank 1 up to the level xx of the required vapour zone, the heating of the water being by electric heater 6. Above the level xx is provided a water-cooled condensing surface 7, and an opening 9 around the rim of the tank allows any uncondensed vapour escaping to be drawn off through pipe 8. The articles to be coated are passed in a continuous path through the concentrated vapour zone 4 into the hot coating liquid 3 and then upwards from the plant through the vapour zone into the atmosphere. By varying the path as at A or B and/or the relative depths of the liquid and vapour zones the times of immersion in the vapour and in the liquid can be varied as required. The articles may also be rotated whilst in the vapour zone to assist draining and evening of the coating on the articles. Coating compositions for application to polyolefinic surfaces are formed of resins soluble in trichloroethylene or perchloroethylene, e.g. chlorinated polymers and alkyd/ urea resins. Particularly suitable chlorinated polymeric are chlorinated rubber, chlorinated polyisoprene and the soluble varieties of chlorinated polypropylene, chlorinated polyethylene and chlorinated polyvinyl chloride. Other resins that are soluble in the chlorinated hydrocarbon solvent employed, for instance, acrylic resins, may be mixed with these chlorinated polymers, and the compositions will usually include plasticizers or extenders such as the chlorinated paraffinic oils and waxes and the chlorinated diphenyls. Such mixtures may be employed as clear lacquers or they may contain opacifiers, pigments, dyestuffs and metallizing powders.

Abstract: 910,297. Coil coating methods. CHRYSLER CORPORATION. May 3, 1961 [May 12, 1960], No. 16002/61. Class 35. A method of protectively coating electrical coils such as stator or rotor windings with an insulator comprises the steps of applying a source of electrical power to the coils to heat the same resistively and then bringing the heated coils into contact with powdered fusible and subsequently hardenable resin whereby the resin is picked up by the coils in sufficient quantity to fuse and subsequently set to form a continuous coating on the coils. Fig. 3 shows a slotted stator structure coated on the inner parts of its upper and lower surfaces with a plastic layer 14, the inner face 16 being left uncoated as shown in the sectional view of Fig. 2. The coils are heated by connecting them to a source of power and are then dipped into or sprayed with fluidized thermosetting or thermoplastic resin powder which sticks to the heated insulating covering for the wires of the coils. The powder may be of thermosetting epoxy resin or of thermoplastic cellulosic, vinyl, nylon, polyethylene or chlorinated-polyether resin. The material used is preferably an epoxy resin blended with dicyandiamide curing agent. In this case sufficient heat must be applied to the resin to cure it as well as to cause it to fuse to the surface of the windings. If insufficient heat is retained by the coils for this purpose a conventional curing oven may be used to provide the final step.

Title: Process for the manufacture of articles resistant to gaseous corrosion
IPC: C21D1/76
Filed: 1935-06-04
Abstract: To impart to an alloy article the property of resistance to corrosion by a given gaseous substance, e.g. oxygen or sulphur, at a given temperature or partial pressure, the alloy containing an alloying element which gives with said gaseous substance a compound having a dissociation pressure lower than that of the corresponding compound of the basis metal or metals but which is not present in quantity sufficient to give satisfactory corrosion resistance when exposed to the gaseous substance at the given temperature and pressure, the article is heated in an atmosphere containing the said gaseous substance at a partial pressure above the dissociation pressure of the compound of the gaseous substance and the alloying element, but below the given partial pressure and so low that a coating is produced which consists to such a preponderating extent of the compound of the alloying element and is sufficiently thick, compact, and adherent that the article is resistant to corrosion under the given conditions. The partial pressure of the gaseous substance may be progressively increased during the treatment and at the beginning of the treatment may be between the dissociation pressure of the compound of the gaseous substance and the alloying element and that of the compound of the gaseous substance and the base metal. For example a ferrous alloy containing 12 per cent of chromium or 4 per cent of aluminium may be rendered resistant to corrosion by oxygen at about 1000 DEG  C. by heating at about 1000 DEG  C. in oxygen at a pressure of between 0,1 and 5 mm. of mercury.  The partial pressure used varies according to the percentage of alloying element, the temperature of treatment, and the temperature and pressure at which the article is to be used.  In the case of ferrous alloys and oxygen it in no case exceeds 10 mm. of mercury. Corrosion resistant decorative articles may be made by the process, different parts of an article being made of metal containing different alloying elements. For example one part may be made of copper containing chromium, another part of copper containing aluminium, and a third part of copper containing cobalt, the article being heated in oxygen at a low pressure, e.g. between 0,1 and 5 mm. of mercury, to form a green, gray, and blue article, the surface consisting mainly of chromium oxide, aluminium oxide, and cobalt oxide.
