Abstract: 956,645. Gramophone centre-posts. MAGNAVOX ELECTRONICS CO. Ltd. Oct. 9,1962 [June 14, 1962], No. 22937/62. Heading G5R. A symmetrical post-body 1 has a retractable shelf 5 opposite a recess 16 in the post. A pusher member 4 with a nose 13, pushes the lowest record 6 over the shelf 5 whereupon it falls over the lower part of the recess 16 Figs. II, III the other records being retained by the full diameter of the post engaging the next-lowest record, just above the recess 16, Fig. II. The weight of the remaining records acting on top of the nose 13 depresses it against the action of a light spring 12 and the engagement of the surface 17 with a pin 8 joining the duplicate members forming the shelf 5 causes retraction of the nose 13 inside the post, Fig. IV. When the weight of the records is taken by the shelf 5, the spring 12 restores the member 4 to its initial position, Figs. V#I. After play, the stack of records may be lifted straight off the post 1, a surface 18 being contacted by the records to retract the shelf 5 against the action of a spring 11. The embodiment of the spindle in a consecutive-access automatic gramophone is briefly detailed in connection with Figs. VII and VIII, (not shown).

Title: Improved process of making fluorocarbon carbonyl fluorides
IPC: C07C53/50
Filed: 1955-08-16
Abstract: Saturated fluoro-carbon carbonyl fluorides are prepared by thermally reacting a saturated perfluorocarbon-difluoromethyl-sulphonyl fluoride with nitrogen dioxide or nitric oxide at 450-650 DEG  C. in the vapour phase. Suitably a perfluoroalkanemonosulphonyl fluoride having more than one carbon atom such as perfluoro-octanoyl fluoride, is reacted with 3 to 7 mols., more preferably 3.5 to 4 mols. of NO2 at 550 DEG  C.  The reaction follows the equation: <FORM:0776507/IV(b)/1> where m is 1 in the case of monofunctional compounds, but is 2 or more in the case of di- or polyfunctional compounds, and Rf is a saturated fluorocarbon radical which may be either acyclic, cyclic or a combination of cyclic and acyclic radicals.  The reaction is conveniently carried out by passing the reactants through a tube of nickel, nickel alloy, steel or platinum maintained at the desired reaction temperature.  The product may be recovered by fractional distillation or may be hydrolysed with a base to form the corresponding fluorocarbon carboxylate salt, or with water to form the fluorocarbon carboxylic acid.  Examples describe the preparation according to the invention of: (1) perfluoropentanoyl fluoride, recovered as the potassium salt of the corresponding acid: (2), (4) and (5) perfluoro-octanoyl fluoride, together with minor amounts of perfluoroheptanoyl fluoride by-product, both isolated as the free acids; and (3) perfluorodecanoyl fluoride and the corresponding acid.  Reference is also made to the preparation of perfluorosebacyl difluoride.  Starting materials.  The perfluorinated fluorocarbondifluoromethyl sulphonyl fluorides used as starting materials are made by electrolysis of a mixture of a hydrocarbon sulphonyl fluoride or sulphonyl chloride and hydrogen fluoride. Several monofunctional compounds are listed.  Specifications 659,251, 718,318 and 758,467 are referred to.

Abstract: 501,806. Coloured artificial filaments, films, etc.; dyeing. ELLIS, G. H., and BROWN, F. Sept. 1, 1937, No. 23924. [Classes 2 (ii) and 15 (ii)] Coloured filaments, straws, foils and the like are prepared by incorporating, in a spinning solution of a cellulose ester or ether a sulphonated dyestuff soluble in the spinning solution but having little or no direct affinity for the cellulose derivative when applied by ordinary dyeing methods, and thereafter spinning the solution into a setting medium. The dyestuff incorporated may be a substantive cotton dye, and it may be of such nature and used in such quantity as to produce a neutral shade on the filaments or the like. These neutral coloured filaments may then be dyed in dark shades with the aid of a colouring material having a direct affinity for the materials. The neutral shade of the filaments can be discharged with discharging agents, so that white or coloured discharge effects may be obtained on the materials after they have been topped with dischargeable direct dyes. The topping colours may be applied uniformly or locally. In an example, extracted and recrystallized Carbide Black D is incorporated in a cellulose acetate spinning solution which is spun into an evaporative atmosphere. The grey yam obtained is scoured in soap solution and dyed by adding 1-amino, 2-methyl anthraquinone. Specifications 282,036, 313,451, [both in Class 15 (ii)], 439,260, and 460,575 are referred to.
