Filed: 1945-08-24
Abstract: 597,708. Weighing and sorting apparatus. AVERY, Ltd., W. & T., and JONES, W. Aug. 24, 1945, No. 21683. [Class 143] Weighing and sorting apparatus of continuously rotating character has the goods scale pan connected with mechanism automatically operable to discharge the contents at a given point in the cycle of rotation if the weight is correct, the operation of the mechanism being governed by the interaction of a pair of spring-coupled plungers one of which is positively connected to part of the release mechanism. Twelve weighing scale units 4, Fig. 1, are arranged on a rotating table 5, operatives 6 applying the load, for example tobacco, in bulk, and operatives 8 effecting final loading or unloading of the pans. Each unit consists of a beam 10, Fig. 2, having a pan 12 and a standard weight 11. A lamp 13 projects an image of an index, situated between a condenser 15 and lens 16, which is reflected by a mirror 18 on to a screen 19 whereby approach to the point of balance is observable. A dashpot checks the beam oscillations. The pan 12 consists of two parts hinged at 12a, 12b to permit opening along a centre line. A frame 21 mounts catch levers 22, 23, pivoted at 12a, 21b respectively, a detent 23a of the latter normally interlocking with an extension 22a of the former. A lifting frame 24 carries a plate 24a aperture to receive a pair of cylinders dependent from frame 21 to prevent lateral swinging of the pan. Beneath table 5 are twelve brackets 25 each mounting a slidable spring-loaded plunger 26 having a roller 27 which contacts a cam 28 at the point where discharge of the pan is required. Co-axial with plunger 26 is a spring-loaded plunger 29, coupled therewith by a compression spring 31 to leave an intervening gap, and mounted in a bracket 30. Plunger 31 mounts the frame 24 which carries rods 24b with rollers 24c adapted to contact the levers 22, 23 and discharge the pan 12 after release of the locking mechanism. A feeler 29a on plunger 29 is disposed below a slotted gate 32 above which is a stop plate 33 so that if the weight of the load is not correct, the feeler fouls the gate and plunger 29 will not rise to discharge the pan which returns on the table for correction.

Abstract: 485,437. Rolling sheets. RADIOAKT.- GES. D. S. LOEWE. Aug. 6, 1937, Nos. 21712 and 21713. Convention dates, Aug. 7, 1936 and July 9, 1937. [Classes 83 (ii) and 83 (iv)] Metal sheet is rolled in a succession of different directions to produce uniform qualities in the sheet so that it can be used, e.g. for producing a Nipkow scanning disc free from distortion at high speed of revolution. A sheet of round, hexagon, &c. shape, considerably larger than the required Nipkow disc shown dotted, is rolled from side to side along diametrical or curved paths spaced at a constant angle to each other and all passing through a centre, e.g. as in Fig. 5. The repeated passes at angular spacings are performed until the whole disc has been rolled either in one revolution of the disc or if the angle is not an integral sub-division of 360‹ then a number of disc revolutions are performed with rolling along each angular displacement. The angular displacement of rolling direction may be so selected, e.g. as in Fig. 9, where the last rolling direction 9 is at right-angles to the first rolling direction 1.

Patent GB-483301-A (GB)
Title: Improvements in substances useful as wetting, washing and purifying agents and in processes of making the same
Filed: 1936-08-10
Abstract: Wetting, washing and lathering agents are obtained by the sulphonation of oxyalkylpolysulphides containing at least 16 carbon atoms in the molecule.  The oxyalkylpolysulphides may be obtained by treating the oxyalkylhalogen compounds with alkalipolysulphides or with alkali sulphocyanides followed by saponification.  In examples: (1) 10-chloroctadecanol is treated in alcohol with sulphocyanide under pressure and octadecanol-10-disulphide obtained by saponification with alcoholic caustic soda; sulphonation is effected with oleum in carbon-tetrachloride; (2) bromine is allowed to drop into a petroleum ether solution of poppy oil alcohol and the resulting tetrabromstearin-alcohol is treated with alcoholic sodium sulphide and sulphur under pressure; the product, which is substantially octadecenoldisulphide is sulphonated with chlorsulphonic acid in chloroform.  Specifications 435,039 and 437,590 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the treatment of substances with baths containing products obtained by the sulphonation of fat alcohols in which the carbon chain is interrupted by bivalent sulphur.  The sulphur may be present in the form of mercaptan, sulphide, polysulphide or thiocyanogen groups.  Sulphonated octadecenolsulphocyanide (obtained from dichloroctadecanol and sodium sulphocyanide) is mentioned.  In a further example, chlorine is led into an alcoholic solution of a mixture of alcohols obtained from oleic acid and the product heated with sodium sulphide and sulphur. The resulting mixture of octadecanol and octadecenoldisulphide is sulphonated in carbontetrachloride with chlorsulphonic acid.  The sulphonated product may be used in pickling iron sheets with sulphuric acid to prevent the metal being attacked.  Solutions containing the products as well as ordinary sulphonated alcohols have improved capillary activity.  Mention is made of using the products for washing wool and as a hair shampoo.  This subject-matter does not appear in the Specification as accepted.
