Title: Polymeric aluminium acyloxides
IPC: A61K8/34
Filed: 1972-09-29
Abstract: 1410778 Aluminium acyloxide polymers UNILEVER-EMERY NV 29 Sept 1972 [1 Oct 1971] 45000/72 Heading C3R Aluminium acyloxide polymers having the formula where R is a branched chain, saturated, aliphatic radical containing 9 to 24 carbon atoms, R<SP>1</SP> and R<SP>2</SP> are alkyl groups having 1 to 8 carbon atoms or acyl groups having 9 to 24 carbon atoms and n is an integer, are obtained by reacting an aluminium alkoxide with water and a branched chain, saturated, aliphatic monocarboxylic acid containing 10 to 25 carbon atoms at 50‹ to 100‹C. until liberation of alcohol ceases. The polymers may be dissolved in non-polar liquids to form gels, a carboxylic acid being added as an additional ingredient. In examples polymers are obtained by reacting aluminium isopropoxide and water with isostearic acid, and are used to form gels from mineral oil, mineral spirit, chloroform and isopropyl myristate.
Patent GB-450058-A (GB)
Abstract: 450,058. Totalizators. WATSON, H. G., 16, Moorhead Street, Camberwell, and MITCHELL, H. C., 21, Bloomfield Road, Ascot Vale, both in Victoria, Australia. Aug. 12, 1935, No. 22715. Convention date, Aug. 13, 1934. [Class 106 (i)] An odds-calculating mechanism for a totalizer comprises an odds scale which is moved a distance proportional to the logarithm of the total amount to be distributed and a number of horse indicators which are moved distances proportional to the logarithms of the amounts on each horse, the relative positions of the scale and indicators indicating the odds. The apparatus is described as used for both win and place betting. As shown, a number of odds scales 16 are moved together down the totalizator board 10, the movement being a function of the logarithm of the total amount staked whilst horse indicators 1-12 are moved down distances proportional to the amounts on the respective runners. The amount on a runner is set, as each stake is received, by rotating the relative shaft 39 either automatically or by hand. The cam follower 33 is thus moved away from the stop 82 and the relative camplate,whichislogarithmically cut, is moved upwards by the weight of the indicator plate 12. The indicator thus falls an amount proportional to the logarithm of the stake, the relative movement of cam plate and indicator being determined by pulleys 23, 26. At each revolution of any horse shaft 39, a circuit is completed to solenoid 64 controlling the totals shaft, which is identical with the horse shafts 39, Fig. 5. The totals cam is thus allowed to move up a distance proportional to the log of the total amount staked and this movement is transmitted through pulleys 58, 56 and 52 to all the odds plates 16 which move down a proportional distance. The odds plates 16 are marked in odds so that the arrow on any indicator plate indicates on the odds plate the odds prevailing. To ensure correct setting of the cam plates for the first three bets, the notches 79 co-operate with cam plate 80 whilst notches 78 ensure correct setting in the next seven positions. When the apparatus is to be used for place betting the pulley 58, Figs. 2 and 10, is eccentrically mounted and is provided with an adjusting handle 79 so that the odds plates may be moved to indicate the odds when payments are to be made on two, three or more runners. The amount staked on each runner is indicated by a counter mounted adjacent the relative shaft 39 and operated through gearing from the shaft. The spring 75, tensioned by pulley 77 which rotates with pulleys 52 compensates for the increasing weights of the odds plates as the plates are lowered.

Abstract: 1410180 Electromagnetic vibrators INTERNATIONAL MECHANICAL VIBRATION LABORATORY Inc 29 Sept 1972 [2 March 1972] 45078/72 Heading H2A An electromagnetic vibrator which can be made to vibrate in either of two directions comprises a permanent or electro-magnet system providing at least one pair of opposed poles N, S and which can be put into either of two positions by rotation of a shaft 9, and an A.C. energized coil 14 extending arcuately around the shaft and arranged such that in the two positions of the magnetic circuit different portions of the coil lie between the poles and hence vibration of the coil takes place in different directions. In the drawings the magnetic system comprises two C-shaped magnets 10 and the coil 14 is ring- shaped. When the magnets are vertical, horizontal limbs of the coil lie between the poles and the coil vibrates vertically. When the magnets are horizontal, vertical limbs of the coil lie between the poles and the coil vibrates horizontelly. The coil is mounted on a support plate 13 fixed to a table 12 for a load to be vibrated. Rollers 16 are moved to engage either vertical or horizontal limbs of L-shaped plates of the corners of the support plate 13 according to the direction of vibration. The table 12 is also supported by air spring devices 15.

Abstract: N-Carboxy anhydrides of amino acids of the general formula <FORM:1038913/C2/1> in which R1 and R2 represent a hydrogen atom or a hydrocarbon group which may be substituted or they may be connected to form a ring together with the carbon atom to which they are attached, are obtained by reacting amino acids with phosgene in a reaction solvent, distilling off the reaction solvent at a temperature between -40 DEG  and 40 DEG  C., until 1-2 c.c. of the reaction solvent per gram of the a -amino acid used is left, separating crystals of N-carboxy anhydride product and then drying the same.  The reaction temperature and the temperature at which excess phosgene is removed is generally in the range from 10 DEG  to 65 DEG  C.  The temperature of the recrystallization step is preferably less than 30 DEG  C.  The product is preferably dried at a temperature below 60 DEG  C. and also under reduced pressure. Suitable reaction solvents are 1,4-dioxan; 1,3-dioxan; 4,4-dimethyl-1,3-dioxan; tetrahydrofuran, methylene chloride; 1,2-dichloroethane and acetonitrile. Suitable amino acids for use in the process include glycine, alanine, phenylalanine, leucine, isoleucine, valine, aspartic acid glutamic acid, a -amino adipic acid, ornithine, lysine, arginine, cystine, methionine.  Examples are given for the production of N-carboxy anhydrides of L-alanine, g -methyl-L-glutamate and L-leucine.
