Title: Improvements in or relating to apparatus for plucking feathers
Inventor: TAYLOR JOHN
IPC: A22C21/02
Filed: 1960-07-03
Abstract: 915,639. Plucking poultry. JOHNSONSTEPHENS Ltd., GORDON. July 14, 1961 [June 3. 1960], No. 19797/60. Class 28 (2). In a feather-plucking apparatus a chain conveyer 6 carries poultry between two sets of rubber picking fingers 12 which are rotated about horizontal shafts 2 which are parallel or converge slightly at the outlet end, each set of fingers comprising single peripheral rows, stepped if desired, of fingers, on a plurality of individual carrier drum members 9, 10. Drums 9 are secured to and rotated with the shaft 2, while intermediate drums 10 are mounted by bearings 14 on the shaft and rotated in the opposite direction by means of integral pulleys 15 on each drum being driven by a belt from slightly larger pulleys 16 secured to a countershaft 5 rotated by a motor 4 at the same speed as shaft 2. The arrangement is such that the downwardly-striking fingers 12 on drums 10 rotate at greater speed and therefore exert a stronger picking action than the upwardlystriking fingers. The track of the conveyer is inclined in the vertical plane to the axes of shafts 2 and by turning a handle 8 the shafts 2 themselves may be inclined to the vertical.

Patent GB-358436-A (GB)
IPC: C08B3/00
Filed: 1930-07-05
Abstract: Esters of cellulose containing organic acid radicles, are prepared in the presence of nitrogen dioxide or tetroxide, or of nitric oxide in conjunction with oxygen.  An acylating agent containing dissolved nitrogen dioxide may be used.  The nature of the products depends on the conditions.  Thus, when cellulose, pretreated by one of the usual methods, is acetylated under normal conditions with acetic anhydride containing about 3 per cent of nitrogen dioxide, a chloroform-soluble ester free from nitrogen is obtained, which must be hydrolysed to render it soluble in acetone, e.g. by treatment with sodium bisulphate and dilute acetic acid.  When, however, the acetic anhydride contains 4 per cent or more of nitrogen dioxide, esterification occurs in a relatively short time, and an acetone-soluble nitro-acetate is obtained directly; the ester is soluble also in chloroform, ethylene chloride, dioxane, and ethyl acetate.  The nitrogen oxide may also be dissolved in other components of the reaction mixture, or may be bubbled through the mixture.  The cellulose may be pretreated in any usual manner, e.g. with glacial acetic acid containing sulphuric acid, with or without phosphoric acid, or, as described in Specification 345,235, with glacial acetic acid containing nitrogen dioxide or tetroxide, but pretreatment is not essential.  The cellulose may be scrap cotton cloth, long-fibred cotton, linters, high-grade wood pulp, or cruder products containing resinous impurities, which may be filtered off after the esterification.  In examples, (1) cotton linters are pretreated at 37 DEG  C. with glacial acetic acid containing a little sulphuric and phosphoric acids, and after about 4 hours acetic anhydride containing nearly 6 per cent of nitrogen dioxide or tetroxide is added; the nitro-acetate is isolated as usual after 3 hours, but this time may be reduced by increasing the proportion of nitrogen oxide or the time of pretreatment; (2) cotton linters are treated with acetic acid containing a little sulphuric and phosphoric acids and with acetic anhydride containing 4 per cent of nitrogen dioxide; the reaction proceeds at 20-50 DEG  C. for 24-48 hours. Cellulose propionates, butyrates, &c., containing combined nitrogen may be similarly prepared, the reaction mixtures containing either acetic acid or the acid corresponding to the acylating agent used. The Specification as open to inspection under Sect. 91 (3) (a) covers the manufacture of cellulose esters in general in the presence of any nitrogen oxide.  This subject-matter does not appear in the Specification as accepted.
