Title: Mixed anhydrides of boron acids and amino carboxylic acids
IPC: C07F5/02
Filed: 1960-06-27
Abstract: Mixed anhydrides of aminocarboxylic acids with dialkylborinic acids, diaryl borinic acids, dicycloalkylborinic acids, alkylboronic acids, arylboronic acids and cycloalkylboronic acids are added to lead-containing fuels for sparkignited internal combustion engines and mixed with sulphur and phosphorus compounds of the type described in Specification 829,635 to hinder the formation of deposits on cylinders.ALSO:The invention comprises mixed anhydrides of aminocarboxylic acids, including aminoalkyl, aminoaryl and heterocyclic acids which may contain ether or thioether linkages, with dialkyl borinic acids, diaryl borinic acids, dicycloalkyl borinic acids, alkyl boronic acids, aryl boronic acids and cycloalkyl boronic acids.  The novel compounds may be made by reacting boron trialkyls, boron triaryls, or boron tricycloalkyls with aminocarboxylic acids at temperatures which are sufficiently high to effect a reaction but below the decomposition temperatures of the components and products, with the splitting off of hydrocarbon from the boron hydrocarbon.  The reaction is preferably effected by mixing the components, optionally with a solvent, such as a high-boiling hydrocarbon, heating to reaction temperature with stirring and maintaining the temperature until the calculated quantity of hydrocarbon is evolved.  Some reactions proceed at 80 DEG C. but temperatures of 130-160 DEG C. are generally necessary.  It is advantageous to use an inert atmosphere, e.g., nitrogen of argon. Specified amino-acids are glycine, a -alanine, cysteine, lanthionin, phenylalanine, tryptophane, a -aminobutyric acid, methionine, valine, norvaline, o-methyl-serine, leucine, isoleucine, nor-leucine, b -alanine, b -aminobutyric acid, anthranilic acid, 6-aminocaproic acid and p-aminobenzoic acid. Examples describe the preparation of B-dipropyl boroxazolidone, B-dipropyl-C-methyl boroxazolidone, B-dipropyl-C-ethyl boroxazolidone, B,B, - dipropyl - C - (methyl mercaptoethyl)-boroxazolidone, B - propyl - benzboroxazone, and the mixed anhydride of dipropyl borinic acid and 6-aminocaproic acid.

Filed: 1924-09-26
Abstract: 242,742. British L. M. Ericsson Manufacturing Co., Ltd., Norbury, W. D., and Bates, F. Sept. 26, 1924. Condensers of the variable type with two or more controls acting on independent sets of conductors, have an outer fixed bush forming the bearing of a hollow spindle controlling one set of conductors and having mechanical clearance from the spindle controlling the second set of conductors, which latter spindle is concentric with the hollow spindle and is held in bearings separate from the hollow spindle and its bearing so there is no tendency for motion of one to move the other. As applied to a condenser having three controls, the main section A is controlled by a spindle B and handle C, the spindle having a bearing in a fixed plate H. The second section E is controlled by a hollow spindle F and handle G, the spindle fitting in a stationary bearing D. The third section E<1> is controlled by a handle G' on a hollow spindle F<1> fitting in a stationary bearing bush D<1>. Thus there is no tendency for friction drag between the spindles. If only two controls are required, the parts D - - G are omitted.

Filed: 1925-09-14
Abstract: 251,164. Worthington, R. C., and Milner, H. Sept. 14, 1925. Addition to 239,937. Variable-speed and reversing gearing comprises two-speed or three-speed epicyclic gearing in which the speed changes are effected automatically in accordance with the load by disengaging clutches by cams, and so allowing detents to act. The two-speed gear has a single train, and a further speed or speeds are obtained by adding a train or trains. Planet gears 17, Fig. 1, carried by the driven shaft 19 mesh with side gears 16, 25. The gear 16 is in the two-speed gear fast on the driving-shaft. The gear 25 is loose and is connected through coacting face cams 24, 23, Fig. 6, with a friction clutch member 22. The member 22 is normally held by a spring 26 in engagement with a friction surface 21 upon a planet-carrying casing 20. This clutch causes the train 16, 17, 25 normally to turn solid. On increase of resistance, the cams 24, 23 act to withdraw the member 22 away from the train, upon which the freed member 22 is picked up and prevented from running loosely backwards by a detent 29. The planets 17 then roll round on the fixed gear 25 yielding a reduced speed. The three-speed gear shown comprises a second train 5, 6, 14, a second clutch 11, detent 29, and pair of cams 12, 13. This train either drives the gear 16 solid with driving-shaft 2 or at a reduced speed. A reversing-gear is shown on the right. In the configuration shown, there is a forward drive of a tail shaft 34 from the shaft 19 through clutch pins 33b upon a sliding toothed gear 33. When the gear 33 is slid to the right, a reversed drive passes through a train 32, 38, 36, 37, 33. A middle position of gear 33 yields no drive.
