Abstract: 807,355. Closuring containers. FORDS (FINSBURY) Ltd. Aug. 22, 1957 [Aug. 22, 1956], No. 25662/56. Class 125(2). Relates to apparatus in which upward movement of container C having a loose skirted cap D raises a pressure plate 1 carried on a shaft 2, this motion raising a sleeve 3 to which are pivoted at 18 crimping fingers 23 which are thus caused to swing about their fixed pivots 8 to engage the cap skirt. According to the invention, shaft 2 is so coupled to sleeve 3 that when, after crimping, the sleeve meets a stop 9 the plate can move up relative to the sleeve so that the cap skirt is positively removed from the fingers 23. As shown, spring-loaded balls 13 in the sleeve engage selectively grooves 11, 12 in the shaft, cooperating with the former in the crimping position and jumping into the latter to free the cap from the fingers. When the container is lowered, sleeve 3 first descends to open the fingers under the influence of spring 6 which then restores the shaft 2 and its plate 1 to the position in which balls 13 engage groove 11.

Abstract: 1,179,582. Production of thiazolidine ester derivatives. R. B. WOODWARD. 3 Feb., 1967 [22 Feb., 1966; 17 June, 1966], No. 25858/69. Divided out of 1,179,581. Heading C2C. Acyloxy groups are introduced into the 5-position of a 5-unsubstituted, 2,2-disubstituted 3-acyl-thiazolidine 4-carboxylic acid derivative by treatment with an alkoxy radicalforming oxidation reagent in the presence of a reagent capable of furnishing acyloxy groups by homolytic cleavage. The reaction may be effected in a solvent or solvent mixture at a temperature of 0-100‹ C., optionally under an inert atmosphere, or the reaction may be effected by irradiation, e.g. with U.V. light having a main wavelength range above 280 mÁ. The alkoxy radical-forming oxidation reagents employed may be those which are suitable for the one-electron oxidation of alkanols and/or are capable of forming an alkoxy radical by homolytic cleavage, examples of such reagents being alkyl esters of hyponitrous acid and alkanols in the presence of oxidizing heavy metal salts (particularly acylates) which may be prepared in situ. The reagents capable of furnishing acyloxy groups which may be heavy metal acyl compounds, e.g. acylates, or mixed anhydrides of hyponitrous acid with organic carboxylic acids. Alternatively the principles of the oxidation reagent forming the alkoxy radical and the reagent furnishing the acyloxy group may be combined by employing alkoxy-heavy metalacylates of oxidizing heavy metals, or anhydrides of alkyl-half esters of hyponitrous acid with organic carboxylic acids. Substituent groups in the products may be converted into other substituent groups and/or a resulting mixture of isomers may be separated into the individual isomers. The specific examples describe the production of 5#-acetyloxy-5#-benzoyloxy., 5#-propionyloxy- and 5#-t.-butyloxy-derivatives of L - 2,2 - dimethyl - 3 - t. - butyloxycarbonylthiazolidine-4-carboxylic acid methyl ester, L - 2,2 - dimethyl - 3 - t. - butyloxycarbonyl - 5# - acetyloxythiazolidine 4 - carboxylic acid - N - phenyl sulphonylamide and L-2,2-dimethyl-3 t - butyloxycarbonyl - 5# - acetyloxy - thiazolidine 4-carboxylic acid 2,2,2-trichlorethyl ester, and certain by-products which are also obtained.

Abstract: 260,293. International General Electric Co., Inc., (Assignees of Allgemeine Elekiricitõts-Ges.). Oct. 23, 1925, [Convention date]. Regulating combustion. - In a steam-boiler plant a series of devices for regulating combustion are brought into operation successively, the primary device serving to regulate the fuel supply in accordance with the boiler pressure, such regulation serving to act on a smoke tester which influences the induced draught device. The combustion chamber pressure is in turn varied and subsequently the undergrate blast. The apparatus for regulating the fuel supply comprises a motor a on the speed of which depends the quantity of fuel applied to the furnace. The speed of this motor is determined by the voltage of an exciting machine b driven by a motor c. To the terminals of the exciting machine are connected the field winding d of the motor a and the field winding e of the exciting machine h in the circuit of which is a variable resistance f adapted to be alternately put in circuit and short-circuited by a vibratory regulator consisting of a voltage coil g connected to the two poles of the exciting machine and the contacts i, k. The pressure in the boiler acts upon a piston l and adjusts the contact k and so varies the period of vibration of the contact i, the meau excitation of the field winding d, and the speed of the motor a supplying the fuel to the furnace. Similar arrangements may be provided for varying the speed of motors operating the induced draught devices and blowers delivering air beneath the grate.. When it is desired to vary the boiler pressure at which the regulating devices operate with increased load, the contact k is varied in position by a spring m connected to a diaphragm subjected to differential pressure on opposite sides of a diaphragm in the steam pipe.
