Title: Improvements in or relating to the bleaching of keratinous fibrous materials
Inventor: HARRIS MILTON
IPC: D06L4/30
Filed: 1953-06-22
Abstract: Keratinous fibrous material is treated with an aqueous solution containing free formaldehyde and a ferrous salt at a temperature of 65 to 100 DEG C. and pH of 2.8 to 9.5, and is thereafter bleached with aqueous hydrogen peroxide.  The treatment may follow an alkaline scour.  The formaldehyde-ferrous salt solution may include, as a sequestering agent, citric, salicylic, tartaric, lactic or ethylene diamine tetra-acetic acid or their sodium salts, phenanthroline or 2:21-dipyridyl and, as a reducing agent for keratin, a formaldehydedesulphoxylate, hydrosulphite, sulphite, bisulphite or metabisulphite of sodium or zinc.  When the reducing agent, e.g. sodium hydrosulphite, reacts with formaldehyde, the relative quantities are such as to leave free formaldehyde in the bath.  The ferrous salt may be ferrous sulphate or ferrous-ammonium sulphate. The pH of the bath may be adjusted after addition of the fibrous material with alkali or acid.  The fibrous material may be rinsed before bleaching, and the bleaching bath may be an aqueous hydrogen peroxide solution containing tetrasodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate, sodium tetraphosphate, sodium metasilicate, water-glass, oxalic acid or an alkali metal oxalate or a mixture of tetrasodiumpyrophosphate and oxalic acid. The bleaching bath is maintained at a pH between 7.0 and 9.0 with sodium carbonate or ammonium hydroxide and, instead of hydrogen peroxide, the bleaching agent may be an alkali or alkaline earth metal peroxide, or an alkali metal perborate, persulphate or percarbonate.  In examples (1) wool is treated at 82 DEG C. in a bath comprising ferrous sulphate, citric acid, sodium formaldehyde sulphoxylate, formaldehyde and a wetting agent, a pH of 5.5 to 6 being obtained with acetic acid, and after rinsing is bleached with a solution comprising oxalic acid, tetrasodium pyrophosphate, sodium carbonate and hydrogen peroxide (3) karakul is treated at 85 DEG C. and pH 8-9.5 with a solution comprising ferrous sulphate, sodium citrate, sodium formaldehydesulphoxylate, formaldehyde, sodium carbonate and a wetting agent prior to bleaching in a bath having the same components as in (1); (5) alpaca is scoured in a bath comprising sodium carbonate and a wetting agent, is rinsed and treated at 85 DEG C. and pH 3.3-5.9 in a solution comprising ferrous sulphate, citric acid, sodium formaldehyde sulphoxylate and formaldehyde; after rinsing, it is bleached in a bath comprising sodium tripolyphosphate and hydrogen peroxide, the pH of which is adjusted initially with sulphuric acid and then with sodium carbonate during the bleaching. The keratinous materials which may be treated also include cashmere, vicuna, cowhair and goat hair.

Abstract: 1,045,956. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 27, 1965 [April 27, 1964], No. 17599/65. Headings G4C and G5R. Data stored as a deformation pattern on the surface of a thermoplastic layer having a conductive backing member is read by scanning the surface with an electron beam and detecting the scattered electrons, the surface, while normally of high resistance to enable an electrostatic charge pattern to be carried, being energized to render it conductive during reading, a leakage path being provided to prevent charge accumulation on the surface during reading. The thermoplastic layer may have a surface layer of photoconductive material which is optically illuminated during reading. Writing is performed by using the electron beam to produce an electrostatic charge pattern on the surface (unilluminated) and then heating the thermoplastic material by passing a current through the backing member. Alternatively, the thermoplastic layer may itself be photoconductive, or the conductivity during reading may be induced by the electron bombardment itself. During reading the electron beam is moved in a raster while a second electron beam is moved in a raster in synchronism in a display CRT. The beam intensity in the display CRT is controlled from the detector of scattered electrons above. Specification 1,036,295 is referred to.
Patent GB-721240-A (GB)
Title: Oxidation of acyclic hydrocarbons
IPC: C07B35/04
Filed: 1952-07-14
Abstract: Oxidation products of aliphatic alkanes and alkenes of 7 to 12 carbon atoms in the molecule are obtained by heating the hydrocarbons at 50-180 DEG  C., preferably 80-150 DEG  C., with an oxygen-containing gas in the presence of a hydrocarbon hydroperoxide and an alkaline reacting material which is substantially inert under the reaction conditions.  Products have approximately the same number of carbon atoms per molecule as the original hydrocarbon and are chiefly alcohols and ketones.  Air and oxygen are specified oxidizing gases. Tert.-butyl, cumene and cymene hydroperoxides are specified. Hydroperoxides containing a tertiary carbon atom are preferred.  The hydroperoxide is preferably present in amounts of 1-20 per cent of the weight of the reaction mixture.  Alkaline reacting materials specified are sodium, potassium, lithium, magnesium, calcium and barium hydroxides, carbonates, bicarbonates and monoxides.  Specified amounts of alkaline reacting materials range from 0.001 to 3.0 per cent based on the total reaction mixture.  Representative of specified hydrocarbons are heptane, 2,5-dimethylhexane, trimethylnonane, 2-ethylhexene and n-dodecene.  Natural gasoline fractions, alkylation gasolines and straight-chain C7-C10 paraffins obtained by the urea adduct process may also be used.  The oxidation mixture usually comprises aldehydes, alcohols, ketones, esters and acids.  The alcohol yield may be increased by hydrogenating the product before or after isolating the oxygenated products from the hydrocarbons. Conventional hydrogenating conditions and catalysts are used. Further quantities of alcohols may be obtained by saponifying the esters with aqueous alkali.  In examples, in which tert.-butyl hydroperoxide is catalyst: (1) a natural gasoline fraction is heated in a pressure vessel with magnesium oxide and oxygen to yield esters and acids; (2) a natural gasoline fraction; (3) 2,4-dimethylpentane; (4) n-heptane; and (5) octene-1 are heated with sodium bicarbonate in a pressure vessel with oxygen to yield oxygenated compounds, e.g. acids and esters; and in (6) and (7) oxygenated products from (1) and (2) combined and (5) separately are respectively hydrogenated in the presence of Raney nickel and the reduced products saponified with ethanolic potash to yield alcohols.
