Abstract: 1372806 Purifying I.C. engine exhaust gases MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 May 1972 [27 May 1971] 24269/72 Heading FIB [Also in Division B1] Exhaust gas flowing through a container 11 from an inlet 14 to an outlet 15 is contacted by a platinum catalyst in a region 12 and a metallic oxide catalyst in a region 13. The catalysts are deposited on roughly woven sheets of glass fibres which have been de-alkalized by a strong acid. The weight of platinum is not more than 5% of the total weight of the respective support and catalyst, e.g. 4%, and the weight of metallic oxide is not more than 35% of the total weight of the respective support and catalyst, e.g. 22%. The platinum is from 5 to 50%, e.g. 20%, of the total weight of catalysts. A filter 16 of de-alkalized glass fibre sheets may be located upstream of the catalysts. The catalyst supports may extend diagonally across the container, Fig.3 (not shown). The metallic oxide catalyst may comprise oxides of at least two of C o , M n , C r , C u , F e  and T i .

Title: Improvements in lubricating the pistons and cylinders of high-altitude internal combustion engines
IPC: F01M1/02
Filed: 1927-09-15
Abstract: 306,161. Lindequist, S. Sept. 15, 1927. Force-feed lubricating. - The cylinder walls of an internalcombustion aircraft engine are lubricated by oil supplied through flow and return pipes associated with the pistons and connected to a force pump and a suction pump respectively. As shown in Fig. 1, a working piston 2 and a pump piston 4 are arranged in tandem, air being compressed as and when required in the spaces 7, 8 and 9, the space 9 being connected to a corresponding space in a companion cylinder in which works a piston with a crank phase difference of 180 degrees. A force pump and a suction pump are connected to the flow and return pipes 10, 11 respectively, the quantity of oil circulating being regulated by varying the quantity dealt with by the suction pump. The space 9 is separated from the crank chamber by a partition 16. Located between a working cylinder and its charging pump is an oil separator, Fig. 3, containing helical or other guiding surfaces 20 by which oil in the charge is projected against an outer wall and finally deposited in grooves 21 for disposal.

Title: Reactive Esters of Hydroxy-Thiazolidine Compounds and process for their manufacture
Inventor: WOODWARD ROBERT BURNS
IPC: C07D499/00
Filed: 1966-08-30
Abstract: 1,155,028. Thiazolidinyl-ester derivatives and process for their preparation. R. B. WOODWARD. 30 Aug., 1966 [10 Sept., 1965; 9 Dec., 1965; 3 Feb., 1966], No. 24389/68. Divided out of 1,155,020. Heading C2C. Compounds of the formula in which Ac represents an acyl group, X represents the disubstituted carbon atom of the thiazolidine ring, R 1  stands for a free or functionally converted carboxyl group and Y stands for a reactive, esterified hydroxyl group, the compounds wherein Y stands for a hydroxyl group esterified with a strong organic sulphonic acid, a hydrohalic acid or sulphuric acid being claimed as novel, may be obtained by reacting a 2,2-disubstituted-3-acyl-5-hydroxy-thiazolidine-4-carboxylic acid derivative of the formula with an acid or a functional derivative of an acid. The esterified hydroxyl group Y is a hydroxyl group esterified with an inorganic acid, e.g. a hydrohalic acid or sulphuric acid, or with a strong organic acid, e.g. an organic carboxylic acid or an organic sulphonic acid, and the esterifying group may be introduced by treating the hydroxy-starting material with, for example, an acid halide, an acid anhydride or a free acid. The above reaction may be effected in the presence or absence of a diluent, optionally in the presence of condensing agents and/or catalysts in a closed vessel and/or in an inert atmosphere. A resulting mixture of isomers may be resolved by conventional methods, e.g. fractional crystallization or distillation, adsorption chromatography; resulting racemates may be resolved by forming a mixture of diastereoisomeric salts with optically active salt-forming agents, separating the mixture into the diastereoisomeric salts and converting the isolated salts into the free compounds. In specific examples the only examples of the radicals Ac and X which are described are the t-butyloxycarbonyl radical and a dimethyl-substituted carbon atom respectively. The products of the invention may be chemically modified by conventional methods, for example an ester group R 1  may be converted to the free acid, or a free acid group R 1  may be converted to a functional derivative, many of which are described, e.g. ester, amide, azide, hydrazide, nitrile, azocarbonyl or azidocarbonyl.

Patent GB-1064833-A (GB)
Title: Recovery process
Inventor: VONTRESS WILLIAM RUFUS
IPC: C07C17/38
Filed: 1965-06-11
Abstract: Gaseous mixtures of CHF3 and F2C=CF2 are separated by treatment with hexamethylphosphoric triamide, octamethyl posphoramide, dimethyl formamide, or tetraethylene glycol dimethyl ether which preferentially dissolve CHF3, followed by separation of the gaseous F2C=CF2, and recovery of the CHF3 from the absorbent liquid.  The absorption process may be carried out at a temperature of -15 to +35 DEG C and a pressure of 20-150 psig, and the recovery process at a temperature of at least 50 DEG C and below temperatures at which thermal degradation of the absorbent occurs.  In a preferred embodiment of the invention, absorption takes place at 25 DEG C and 25 psig, in a column in which liquid flows downwards countercurrent to the ascending gas mixture which is thus freed from CHF3 which remains in the absorbent together with some F2C=CF2.  The solution then passes to a second column where at 60 DEG C and 1 at. it is stripped of substantially all its F2C=CF2 and of some CHF3, the gas mixture being recycled to the absorption column and the solution passing to a third column where at 90-120 DEG C and 1 at. the CHF3 is substantially recovered.  The absorbent is then stripped of the remaining CHF3 in a 4th column by treatment with F2C=CF2 from the first.  The gas mixture and absorbent are then both recycled.
