IPC: C07C67/055
Filed: 1968-04-02
Abstract: 1,189,091. Carboxylic acids and esters. KNAPSACK A.G. 2 April, 1968 [5 April, 1967], No. 15743/68. Heading C2C. Carboxylic acids I and unsaturated esters of carboxylic acids II, wherein the carboxylic acid II may be identical with the carboxylic acid I, are produced by a process which comprises reacting an olefin cyclo-olefin or diolefine in the presence of an aldehyde, which in structure and number of carbon atoms corresponds to the carboxylic acid I, and in the presence of the carboxylic acid II, each of the said olefin cycloolefin or diolefine, aldehyde and carboxylic acids containing from 2 to 20 carbon atoms, with molecular oxygen or air in the gaseous phase, at elevated temperature in contact with a metallic palladium-containing carrier catalyst. The aldehyde, obtained by condensation of the reaction product and distillation of this condensate, may be recycled to the reaction zone. Examples describe the preparation of vinyl acetate and vinyl isobutyrate with the addition of acetaldehyde, and the simultaneous oxidation of the acetaldehyde to acetic acid. A preferred catalyse contains metallic palladium, gold and alkali or alkaline-earth metal carboxylates.

Abstract: 142,881. Liebmann, A. G. Oct. 2, 1918. Rail joints; chairs with separate jaws, and securing to sleepers; sleepers, securing rails to.- Rails or fish-plates at rail joints are secured to chair plates by means of polygonal clamping- pieces having concentric upper portions which engage with guide-pieces on the chair plates, and eccentric lower portions to engage with the rail flanges so that the rails can be adjusted for gauge and height. Fig. 2 shows a plan view, and Fig. 3 a vertical section. A chair plate 5 is provided on its upper face with abutments 15 strengthened by stay portions 16, 17 and having guideribs 26 on their inner faces. The abutments are staggered and have the opposing portions 18 of the chair plate thinned off. The under surface is provided with hollow internally flanged projections 6 which fit in recesses in the sleeper. Vertical bolts 9 pass upwards through the projections 6, and nuts 7 hold the chair plate and sleeper together. The under surface of the chair plate has a series of lines of recesses of elliptical shape and staggered to grip the surface of the sleeper. The rail A is held in position by means of clamping-blocks 24 which are held down by hollow shanked nuts 33 engaging with the upper portions of the vertical bolts 9. The clamping- blocks are polygonal in form, the upper larger portion being concentric with the bolt and adapted to engage with the ribs 26 on the abutments. The lower portion of the blocks is eccentric and is correspondingly shaped to the upper portion, so that one face can be brought to bear against the edge of the flange of the rail or fish-plate. By changing the positions of the clamping-blocks, the gauge of the rails can be adjusted, and when the height of the rail has to be altered, the clamping-blocks can be loosened and a shim 34 placed under the rail.

Patent GB-946304-A (GB)
Title: Method of preparing partial fatty acid esters of inositol
IPC: C11C3/04
Filed: 1960-05-09
Abstract: Partial fatty acid esters of inositol are prepared by reacting inositol with a fatty acid ester of an aliphatic primary monohydric alcohol having 1-8 carbon atoms or of a polyhydric alcohol having not more than 3 carbon atoms at 50-150 DEG C. in the presence of dimethyl sulphoxide and an alkaline interesterification catalyst. The reaction may be conducted at reduced pressure. After completion of the reaction the catalyst is inactivated by water and/or acid and the reaction mixture freed of dimethyl sulphoxide and unreacted inositol. Specified fatty acid esters are those of methanol, ethanol, hexanol, and octanol, such as methyl, ethyl and octyl palmitates, and completely or incompletely esterified glycol and glycerol. The fatty acid radicals preferably contain 8-22 carbon atoms and preferred starting materials are animal, vegetable and marine oils, and fats. Several catalysts are specified.  The degree of esterification of the inositol is dependent on the molecular proportions of the reactants and, for example, the mono,-di-and tri-fatty acid esters may be separated by crystallisation or solvent extraction.  The partial esters can be used in the preparation of edible products (see Division A2) Examples are given in which inositol is reacted with (1) a hydrogenated mixture of soyabean and coconut oils; and (2) and (3) methyl palmitate. Methyl laurate, glycol mono-oleate and glycol distearate can be substituted for methyl palmitate.ALSO:Partial fatty acid esters of inositol (see Division C2) are used as emulsifiers in the preparation of cakes, candy, chewing gum, licorice, peanut butter and various beverages.  The product of Example 1, in which inositol is reacted with a hydrogenated mixture of soybean and cottonseed oils, may be added to plastic shortenings used in the preparation of baked products.

Abstract: 594,185. Medicated dressings. HERTS PH ARMACEUTICALS, Ltd., ' MITCHELL, S. C., PICARD, C. W., SAWER, G. L., SHAW, T.., ROCHE PRODUCTS, Ltd., BERGEL, F., MORRISON, A. L., and MOSS, A. R. June 27, 1945, No. 16432. [Classes 81 (i) and 81 (ii)] A continuous process for the manufacture of sterile surgical dressings comprises passing sterile surgical gauze or like absorbent - fabric through a solution of penicillin, for example in the form of its calcium salt, or other therapeutic substances, drying the impregnated fabric under sterile conditions to a moisture con- .tent well below that at which the fabric is normally in equilibrium with air of 50 per cent. relative humidity at 70‹F., and enclosing it, preferably after cutting it into portions, in a hermetically sealed sterile envelope. In Fig. I, surgical gauze from a spool or spools 2 is passed through tensionings rolls 4 to an impregnating tank 5 containing a solution of the therapeutic substance in water or an organic solvent, such as acetone or alcohol, or -mixture thereof with water. Thence the gauze passes through rollers 6, which may be eccentrically adjusted, to express fluid therefrom and leave for example 1c.c. fluid per 1gm. of gauze, to a drying tunnel 8 supplied with sterile hot air from chamber 9. If more than one ply of gauze is used, they may be separated by means of transverse glass rods for passage through the tunnel and reunited at the further end thereof. More hot air is supplied to the tunnel than fan 12 will exhaust therefrom. The gauze next passes through rollers 13 to guillotine 14 whence the individual pieces are transported by a shutter to between two layers of plastic film 60, for example of " Pliofilm " (Registered Trade Mark) polyvinyl chloride or other non-permeable film, from spools 16. The film is sterilised by exposure to ultra-violet light lamps 17 and is supplied at a faster rate than the gauze portions. The films containing the gauze pass between rollers 15, under guide roller 18, to sealing jig 18a, and thence to rollers 19 and guillotine 20. Transparent hoods 1 are provided when necessary as a protection against airborne infection. The moving parts are powered from a shaft 26, rollers 6, 13, 15 and 19 through bevel gears and guillotines 14 and 20 and jig 18a through intermittent bevel gears driving a shaft on which is mounted a cam acting on a rocker arm connected with the operating member. The rocker arm which drives guillotine 14 also operates the shutter by means of gear and a bell crank. The top blades of guillotine 14 and 20 are pivoted and have spring loaded adjustments. The air heating of the gauze may be supplemented by electronic heating. Specification 581,234 is referred to.
