Abstract: 254,745. Fischer, H. July 2, 1925, [Convention date]. Addition to 244,090. Sparking-plugs. - Cooling is effected by the provision of a hollow central electrode through which air and water are drawn on the suction stroke. The air enters by way of radial slits 10 in a plug 2 a bore 3 and annular chamber &c. in the block k and one or more openings o in the electrode. The plug 2 is longitudinally bored for the reception of a double-seated valve 6, normally pressed against its outer seating 8 by a spring 7 but being withdrawn on the suction stroke of the engine into contact with its second seating, formed in a plug 9 screwed within the member 2. During the movement from one seating to the other a small quantity of water passes and mingles with the air drawn in through the slits 10. A whirling effect is produced by helically grooving the valve stem. Access of the products of combustion to the bore of the electrode f is prevented by a helically grooved plug h the inner end of which is formed as a conical valve 15 seating in the bore of the electrode. The plug may be in two portions a portion carrying the valve being movable relatively to the grooved main portion.

Title: Process for the manufacture of laevo-ascorbic acid
IPC: C07D307/62
Filed: 1936-06-17
Abstract: Laevo-ascorbic acid (Vitamin C) is obtained by treating 2-keto-laevo-gulonic acid with alkali salts of weak acids in alcoholic solution, and isolating the ascorbic acid from the precipitated alkali salt by treatment with strong acids.  In examples: (1) sodium carbonate is added to a methyl alcoholic solution of 2-keto-laevo-gulonic-acid methyl ester and the solution boiled.  The precipitated sodium ascorbate is filtered, treated with hydrochloric acid, evaporated to dryness, and extracted with absolute alcohol.  Alternatively, hydrochloric acid may be added to the whole reaction solution, and the methyl alcohol distilled off in a vacuum. The ascorbic acid is then extracted as before; (2) a methyl alcohol solution of 2-keto-laevo-gulonic acid methyl ester and anhydrous sodium acetate is heated on the water bath, and the product worked up as in example (1).  Specifications 428,814 and 430,264 are referred to.

Abstract: 1,100,585. Dynamo - electric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 21 May, 1965 [24 April, 1964], No. 17205/64. Heading H2A. A superconducting dynamo-electric machine has a stator member comprising a loop of superconductive wire 1 connected to the axial ends of a cylinder or part cylinder of superconductive material 7. A rotating magnetic field is produced within the cylinder to produce a " normal " patch 2 in the cylinder which repeatedly passes between the ends of the loop to generate increments of persistent current in the loop. The rotating field may be produced by one or more permanent magnets 4 mounted on a shaft or an electromagnetic structure either mechanically rotatable or wound to provide a rotating field. Each current increment may be increased in value by twisting the loop, Fig. 4 (not shown), thereby reducing the leakage flux. The machine may motor if the drive to the magnet system is removed and a power output can be obtained from a second machine when the first is driven if both are connected to a single superconductive loop. Reference has been directed by the Comptroller to Specification 1,014,527.
