Filed: 1940-09-27
Abstract: 546,523. Petroleum asphalt. STANDARD OIL DEVELOPMENT CO. Sept. 27, 1940, No. 14649. Convention date, Oct. 21, 1939. [Class 91] Light coloured plastic material is obtained from the black asphaltic residue of distilled asphaltic petroleum oils by selective extraction or by fractional precipitation from a solution of the residue in a solvent or by a combination of these means, the solution, after separation of the black asphaltenes if present, being decolorized by means of a decolorizing agent prior to the separation of the light coloured plastic material. In the first method, the black asphaltic residue is extracted with ether or with a liquefied normally gaseous hydrocarbon such as propane, butane or a mixture of these, in which only the light coloured material is soluble, the solution is then decolorized and the light plastic material obtained from the ether solution by evaporation or by the addition of a precipitant such as ethyl alcohol and from the hydrocarbon solution by heating. when the material is precipitated. Before extraction with ether, the oil content of the black asphaltic residue may be dissolved out by digestion with methyl alcohol. In the second method, the whole of the black asphaltic residue is dissolved in benzol and the black asphalt first precipitated therefrom by the addition of 50 per cent. by volume of alcohol. The separated solution after being decolorized is then treated with additional alcohol to precipitate the light coloured material. The combination of these methods may be used by removing the oil content and the light coloured material together by extracting the black asphaltic residue with naphtha of A.P.I. gravity 86‹ or with liquefied normally gaseous hydrocarbons. The light coloured material is then precipitated from the separated solution after decolorizing by addition of 50 per cent: by volume of absolute alcohol or when the hydrocarbon solvent is used by heating the mixture. The decolourant may comprise fuller's earth or activated carbon. Illustrative examples are given.

Abstract: 291,057. British Thomson-Houston Co., Ltd., (Assignees of Krape, R. D., and Hamilton, W. S. H.). May 25, 1927, [Convention date]. Regulation, automatic. - In a regenerative braking arrangement for traction motors A<1> - - A<4>, the field windings F<1> - - F<4> are fed by an exciter E, the output voltage of which is subject to an automatic regulator 16. The regenerated voltage of the motors and the voltage of the line act differentially on a relay contact 35 which during the first stage of braking, i.e. while the resistance R<3> is in the braking circuit, keeps the regenerated voltage nearly equal to the line voltage, and also by opening and closing a shortcircuit round a counter e.m.f. motor field winding 13 keeps the regulator 16 out of action. When the resistance R<3> is shunted by a switch 49, the closure of an auxiliary contact 43 makes the action of the regulator 16 independent of the voltage relay 35. The regulator afterwards works automatically to maintain the exciter voltage at a value determined by the setting of a variable resistance R<4>. A differential regulator winding 18 responsive to the strength of braking-current adjusts the exciter voltage inversely, and thus furnishes compensation for fluctuations of line voltage.

Abstract: 1,107,521. Spring starters. SIMMS MOTOR UNITS Ltd. July 17, 1964 [April 18, 1963], No. 15289/63. Heading F1K. A spring starter comprises a main shaft on a first portion of which there is mounted a starter pinion 30 and on a second portion of which there is rotatably mounted a spring assembly 33 for rotation relative to the starter as a whole and arranged for storing the starting effort with a drive arrangement 2, 3, 4, 6 for imparting starting effort to the spring assembly positioned at or towards an end of the main shaft. The rotational force of the sleeve 8 is first utilized in advancing sleeve member 25 with starter pinion 30 by screwing along helical grooves 23 the pawl 27 restraining sleeve member 25 against rotation. With the starter pinion 30 interlocked with the flywheel the shaft 9 is then prevented from rotating and the drive of the sleeve is exerted on the nut 16. Rotation of the nut causes the nut to move to the left compressing the spring 33. The lever 31 is manually depressible to release pawl 27 from engagement with ratchet 26 to enable the main shaft 9 to rotate. The starting effort stored in the spring 33 is then dissipated through the starter pinion which is meshed with the flywheel of the engine. The handle attachment 2 can be turned in the reverse unwinding direction for progressive release of the stored energy. The drive arrangement may be rotated co-axially with the main shaft or about an axis parallel to the main shaft.
