Title: Improvements in clutches for conveying rotary motion
IPC: F16D43/22
Filed: 1919-04-14
Abstract: 137,972. Mansell, Sir J. H., and King, O. C. F. April 14, 1919. Clutches. -- In overload - release clutches for use with electrical machinery &c., pawls 2, secured on pins 3 pivoted in a driving- casing 1, have twin ends 7 pressed together by spring arms 6 and engaging with hooks 15 formed on projecting flanges 14 on. a central driven member 5. The hooks 15 prevent the ends 7 from moving radially under centrifugal action. When overload occurs, the twin pawl ends separate and are thrown outwards by centrifugal action, or at low speeds slide up slopes 17 beside the flanges 14 and close together again at the ridges of the flanges. The flanges 14 are so formed and spaces 13 are so closed by reverse hooks 16 as to prevent the re-entry of the pawls under the action of springs 4 pinned to the pawls until the speeds of the parts 1, 5 approximate, and centrifugal force retains the pawls against the casing 1 until the speed is reduced to a predetermined amount. The flanges 14 near the hooks 16 are so thin as to prevent injury to the pawls 2 on reversal of the drive.

Abstract: 755,132. Gramophones. SELCOL PRODUCTS. Ltd. March 31, 1955 [April 1, 1954]. No. 9575/54. Class 40(2) A sound reproducing device comprises a flat shallow box, a small record rotatably mounted therein, an arm carrying a stylus and having an extension riding against the wall of the box to cause the box to act as a sound radiating diaphragm, and means for returning the arm and stylus to the starting position. In one embodiment, Figs. 1 and 2, the record 4 is mounted on a shaft 3 which may be rotated by a hand crank 6 and movable axially so that a coiled compression spring 7 causes the record 4 to be pressed against a stylus 9 on an arm 8 which is loaded by a spring 12 so that it tends to be swung outwardly to the start of a record. When the hand crank 6 is pulled outwardly against spring 7, the stylus arm 8 becomes free to swing to the starting position. In the second embodiment, Figs. 3, 5 and 6, the shaft 3 carrying the record 4 is not axially movable and the record carries a hook-shaped arm 20 pivotally mounted at 19 and having a spring 23 which normally presses the end 22 against the shaft 3. The stylus 9 is pressed against the record 4 by means of a coiled compression spring mounted between the stylus arm 8 and a nut on a shaft 16 carrying said arm 8. When the stylus 9 reaches the end of the record', the tip 21 of the arm 20 passes under a ramp 18 on the arm 8 and lifts the stylus 9 from the record. As the stylus 9 engages the tip 21 of the arm 20 is forced to swing outwardly against spring 23 until the stylus reaches the outer edge of the record, Fig. 6, at which point the tip 21 passes from beneath the arm 8, and the stylus re-engages the record.

Title: Manufacture of pentamethyleneoxide compounds and pentamethylenesulphide compounds
IPC: C07D309/04
Filed: 1938-03-31
Abstract: 517,414. Nitriles. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). March 31, 1938, No. 9856. [Class 2 (iii)] 4 - Aryl - pentamethylineoxide - and 4 -arylpentamethylenesulphide - 4 - carboxylic acid nitriles are prepared by reacting an arylacetonitrile with a #:#<1>-dihalogendialkyl ether and with a #:#<1>-dihalogendialkyl sulphide respectively in the presence of an agent capable of causing the splitting off of hydrogen halide, for example, sodium, sodium amide or sodium phenylate. The nitriles may be converted into the corresponding acids, amides or esters and the pentamethylene sulphide compounds may be oxidized to the corresponding sulphones. In the examples : (1) benzyl cyanide and #:#<1>- dichlorodiethyl ether are condensed in the presence of sodium amide to give 4-phenylpentamethyleneoxide-4-carboxylic acid nitrile which is converted by sulphuric acid hydrolysis into 4-phenyl-pentamethyleneoxide-4-carboxylic acid amide which is further hydrolyzed by methyl alcoholic caustic potash to 4-phenyl pentamethyleneoxide-4-carboxylic acid. The carboxylic acid is converted to the acid chloride by means of thionyl chloride and into the p-diethylaminoethyl ester. Concentrated hydrogen halides split the oxide ring of the acid yielding halogenated acids which with ammonia or primary amines may be converted into the 4-phenyl pipiridine-4-carboxylic acids; (2) benzyl cyanide and #:#<1>-dichloro-diethyl sulphide or #:#<1>-dibromodiethyl sulphide are condensed in the presence of sodium amide to yield 4-phenyl-pentamethylenesulphide - 4 - carboxylic acid nitrile which is converted (a) by sulphuric and hydrolysis into 4-phenyl-pentamethylenesulphide-4-carboxylic and amide and (b) by methyl alcoholic caustic potash into 4- phenylpentamethylenesulphide-4-carboxylic acid. The nitrile, carboxylic acid and amide yield the corresponding sulphenes on oxidation with permanganate or hydrogen peroxide. With thionyl chloride, the 4-phenyl-pentamethylenesulphone-4-carboxylic acid yields the acid chloride which with #-diethylaminoethanol yields the #-diethylaminoethyl ester. The products are intermediates for the manufacture of remedies. Specification 501,135 is referred to.
