Title: Constant-mesh variable speed gearing
IPC: F16D21/04
Filed: 1933-05-23
Abstract: 406,891. Change speed gearing. PINCH, W. J., 42, Dunsmuir Road, Tremorfa, Cardiff. May 23, 1933, No. 14848. [Class 80 (ii).] Relates to change-speed gearing of the kind in which constant mesh gears n, Fig. 2, loose on a hollow shaft are adapted to be clutched to that shaft alternatively by clutch dogs c sliding radially in bosses within the loose wheels, such radial sliding being effected by a selective cam k sliding within the bore of the hollow shaft. The cam k has a double connection with each clutch dog c, one to engage the dog and one to withdraw it. The engaging connection comprises a radially sliding pin d, Fig. 4, which acts on the dog c through a spring d<2>. The withdrawing connection is positive in its action and comprises a radially sliding pin f acting on a lever g fixedly pivoted at g<1> and engaging into a recess c<1> in the dog c. Double pin and lever connections are shown in Fig. 1. In the clutch B, the pins f have fallen inwards as the dogs c were thrust out resiliently through the springs d<2> and a cam swell j. The dogs c therefore drivingly engage the gear n, Fig. 2, and they are tapered so as to allow overrunning. In the case of the clutch A, Fig. 1, a cylindrical part of the cam k thrusts out the pins f, and therefore the dogs c are withdrawn inwards even though the pins d are also thrust outwards.

Title: Improvements relating to the manufacture of ferric sulphate
IPC: C01G49/14
Filed: 1926-06-12
Abstract: 273,883. Hart, B., Harris, Hart, & Co., Ltd., and Refiners, Ltd. June 12, 1926. Ferric sulphate for use as an active material in the purification of oils, spirits, or fats is prepared from waste materials containing iron as mixtures of oxide or hydrates such as oxidised iron borings resulting from the manufacture of aniline, by the addition of sufficient sulphuric acid to render the iron contents soluble, and then adding sufficient sulphuric acid together with an oxidising agent to precipitate the ferric sulphate. In the case of waste iron from aniline manufacture, the amount of sulphuric acid first added is about one-third of that required to convert the whole of the iron to ferric sulphate with enough to neutralise any impurity such as lime. To the treacly mass so formed, enough sulphuric acid is added to complete the reaction with the addition of an oxidising agent, such as nitric acid, nitrate of soda or other nitrates, or manganese dioxide. The ferric sulphate is precipitated in fine subdivision.

Title: Apparatus for automatically changing bobbins used in the manufacture of textile strands
IPC: B65H67/056
Filed: 1959-05-04
Abstract: 882,128. Winding yarns. COMPAGNIE DE SAINT-GOBAIN. May 4, 1959 [June 9, 1958], No. 15156/59. Class 120(2) In apparatus for automatically changing bobbins in winding textile strands, bobbins are movable transversely to the strand in such a way that an empty bobbin takes the place of a bobbin which has just been filled, the strand being wound on the empty bobbin without ceasing to occupy the same mean position which it occupied during winding on the preceding bobbin, and each bobbin is mounted on a separate frame which carries the mechanism for rotating the bobbin, such that the bobbin's may be moved relatively to one another. In the arrangement shown the strand is being wound on bobbin 1 driven from motor 2, the strand being traversed by guide 4 driven by motor 5. Just before winding on bobbin 1 ends a counter or timer starts the motor 2a to rotate the bobbin 1a. At the same time motor 11a starts and moves the frame 6a to bring the bobbin 1a close to the bobbin 1. This movement stops when cam 23a contacts switch 24a. When winding on bobbin 1 is finished motor 9 is started and this through suitable drive means moves both frame 6, 6a together with bobbins 1 and 1a from right to left so that winding is transferred from bobbin 1 to bobbin 1a. After the frames have been moved the required distance cam 25a on frame 6a actuates switch 26a to stop the motor 9. Motor 2 driving bobbin 1 also stops and motor 11 starts up to move the frame 6 away from frame 6a. The frame 6 can then be tilted forward by the operator the full bobbin removed and replaced by an empty bobbin. The reverse procedure takes place when the bobbin 1a is full.

Abstract: 313,293. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 23, 1928. Azo dyes containing a quaternary group are made (1) by coupling a diazotized unsulphonated amino-arylene thiazol compound of the formula :- in which X = an alkyl or aryl residue and in which the amino group may be attached either to the arylene residue when X is alkyl or to X, when X is an aryl residue, with an unsulphonated azo-component, and treating the azo-compound thus formed with an alyklating agent of the formula: alkyl-O-SO2-Y in which Y is aryl or O-alkyl or (2) the acylated aminothiazol compound is first alkylated and the quaternary base thus formed is diazotized and coupled with an unsulphonated azo component; the acyl group is then removed by hydrolysis. It is assumed that the quaternary group is formed at the nitrogen atom in the thiazolic ring. The following examples are specified. (1) The dye dehydrothio-p-toluidine # #-naphthol is treated with dimethylsulphate or p-toluenesulphonic acid methvl ester in chlorobenzene solution. The product dyes are mordanted cotton yellowish red. A bluish red is obtained starting from dehydrothio-p-xylidene # #-naphthol. (2) Acetyldehydrothio-p-toluidine is treated with dimethylsulphate in chlorobenzene and the hydrolyzed quaternary compound diazotized and coupled with #-naphthol, 1-phenyl-3-methyl-5-pyrazolone, resorcinol, 2 : 7-dioxynaphthalene, a-naphthylamine or ethyl - # - naphthylamine. If m-amino-p-cresolmethylether is used the resulting amino-azo dye may be diazotized and coupled with resorcinol or m-toluylenediamine. (3) The dyestuff dehydrothio-p-toluidine --> 1-phenyl-3-methyl - 5 - pyrazolone is treated with dimethylsulphate with or without chlorobenzene as solvent. (4) The dyestuffs dehydrothio - p - toluidine # acetoacetic acid anilide or o-toluidide, methylketol or acetyl acetone are treated in chlorobenzene with dimethylsulphate. (5) The dyestuff 6-amino-2- methylbenzthiazol # 1-phenyl-3-methyl-5-pyrazolone is treated as in (4). The same product is obtained by alkylating 6-acetamino-2-methylbenzthiazol with dimethylsulphate, hydrolyzing. diazotizing and coupling with 1-phenyl-3-methyl- 5-pyrazoline. 6-Amino-2-methlbenzothiazol is obtained by allowing disulphur dichloride to act on p-aminoacetanilide (Specification 17417/14), treating with alkali to from the o-aminomercaptan which is converted to the aminothiazole by acetic anhydride and hydrolysis.
