Title: Manufacture of new cellulose derivatives
IPC: C08B15/06
Filed: 1930-05-29
Abstract: Cellulose derivatives obtained according to the process of the parent Specification by treatment of cellulose pretreated with alkali with a heterocyclic compound containing one or more N : C-halogen groups, are further treated with a compound that contains a NH, OH or SH group, or a salt of such compound, for example, with water, alkali, alkali sulphides, and amines.  As compared with cellulose, the products are more or less immune to the usual cotton dyestuffs; while the strong affinity to basic dyestuffs exhibited by the products of the parent case may be more or less replaced by a pronounced affinity to acid dyestuffs.  In examples, cotton yarn, loose cotton or linters which has been treated with caustic potash and then with a solution of cyanuric chloride in xylene preferably in the presence of chalk powder, is treated with an aqueous solution of diethylethylenediamine or of ethylenediamine, or with a solution of aniline in benzene, or with aqueous sodium hydrosulphide solution.  Mercerized or unmercerized cotton yarn after treatment with caustic soda and a solution of cyanuric chloride in xylene at 0 to 10 DEG  C., is treated with an aqueous solution of piperazine.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of chloropyrididone and isatin chloride, in the initial treatment of the cellulose material.

Title: Improvements in plasticizing compositions
IPC: C08K5/12
Filed: 1943-10-12
Abstract: A thermoplastic composition containing polystyrene, polymerized methyl methacrylate, or a cellulose ester plasticised with a mixture of alkyl halophthalates containing from 2 to 4 halogen atoms per molecule, the halogen being substituted on the aromatic ring.  The term "polystyrene" includes substituted styrene polymers.  In examples: (1) diethyl and diamyl esters respectively of dichlorophthalic acids were mixed with (a) polystyrene, (b) cellulose acetate, (c) cellulose nitrate, and (d) methyl methacrylate; (2) coating compositions consisting of polystyrene in toluene were mixed with (a) the ethyl esters, (b) the butyl esters, and (c) the amyl esters of chlorinated phthalic acid; (3) a base solution of cellulose acetate in ethyl acetate/acetone was mixed with (a) the ethyl, (b) the butyl, and (c) the amyl ester of the chlorophthalic acid of (1). The halophthalates are prepared by reaction of an aliphatic alcohol (the lower alcohols with not more than six carbon atoms being preferred) with phthalic anhydride previously halogenated until from 2 to 4 atoms of halogen have been absorbed per molecule of the anhydride, or the halogenation may take place after the reaction of the alcohol and anhydride.  Catalysts such as iodine or anhydrous ferric chloride may be used.  Thus, phthalic anhydride is chlorinated in forming sulphuric acid with iodine as catalyst, the product esterified with ethanol in presence of hydrochloric acid gas, and purified.  The chlorinated phthalic anhydride may also be prepared by passing chlorine over iron filings adding the resulting ferric chloride to phthalic anhydride and heating.  Specification 572,160 is referred to.

Abstract: 868,989. Making turbine and like blades. GARRINGTONS Ltd. May 21, 1959 [May 27, 1958], No. 16791/58. Class 83 (2). A turbine or like blade with at least one internal passage for heating or cooling fluid is made by forming at least part of a blank having an internal passage or passages into an elongated cross-section, such as oval, filling each passage with a removable material, forging the blank in a direction substantially parallel to the major axis of the elongated section and finally removing the filler. A hollow cylindrical billet with a cylindrical through bore, Fig. 1 (not shown), is first partly extruded through a die of oval shape and over a tapered mandrel which forms it to the shape of Fig. 2 with a tapered bore 14. The bore is then filled with mild or alloy steel rod or wire and the portion 16, Fig. 3, is forged between dies acting-parallel to the major axis of the extruded section. This causes the bore to be elongated into a slot 15, Fig. 3A. The end portion 20 serves as a locating tap for future operations. Excess metal is then trimmed off, the blank is machined and forged in two stages, Figs. 5, 6 to form the aerofoil profile and twist the blade. The root and aerofoil portions are finally finished by grinding or machining and the filler is dissolved out by acid. Other embodiments are described for forming a shrouded blade, Fig. 8 (not shown), or a blade with a plurality of passages, Fig. 10 (not shown).
