Title: Process for the selective absorption of sulphur compounds from gas mixtures
IPC: C10K1/10
Filed: 1961-04-19
Abstract: A process for selectively absorbing sulphur compounds from gases which contain CO2 and hydrocarbons in addition to permanent gas components comprises contacting the gases with an absorbent comprising an N-alkylated pyrrolidone or N-alkylated piperidone which may have an alkyl group of at the most two carbon atoms attached to the heterocyclic nucleus, the absorption preferably being conducted at 5 DEG  to 25 DEG  C. and circulating the absorbent through absorption and regeneration stages, from which latter stage the absorbed sulphur compounds are recovered. As shown, cooled gas flows through a conduit 1 and heat exchanger 13 to the washing tower 2, in which hydrogen sulphide, organic sulphur compounds hydrocarbons and water are absorbed by the selective solvent introduced through conduit 51.  The partly purified gas flows from the washing tower 2 via the heat exchangers 14 and 15 to washing tower 16 where CO2 is washed out by methanol at low temperature, e.g. -20 DEG  to -70 DEG C.  The pure gas is then led off from the head of tower 16 through the heat exchangers 15 and 13.  The regeneration of the absorbent from washing tower 2 is effected in tower 3 by heating and steam stripping, the absorbent being introduced in the middle zone of the regenerating tower, the lower part 5 of which is operated as a <PICT:0944256/C3/1> stripping zone, and the upper part 4 as a concentration zone. The gas-steam mixture passes from the regenerating tower 3 with from 1 to 10% water content, and the regenerated absorbent is returned to the head of the washing tower 2 by means of pump 51. The regeneration of the methanol absorbent can be effected by two pressure release towers 17 and 18.  The CO2 may be previously washed out at - 20 DEG  to - 70 DEG C., also a washing with heptane, or a light washing oil can be introduced before or instead of CO2 washing for removing gas oil hydrocarbons. For coke-oven gas, the first washing stage may be installed as general gas purification after conventional ammonia separation.

Title: Improvements in weighting animal fibres
IPC: D06M13/256
Filed: 1932-05-21
Abstract: Animal fibres are weighted by treatment with an aqueous acid solution containing at least 10 per cent. by weight calculated on the fibre sulphonated aliphatic amides having the formula R1 CON R2 R3 SO3 H in which R1 and R2 are aliphatic radicles and R3, hydrogen or an aliphatic radicle.  Instead of the sulphonated amides their salts may be used and R1 preferably contains at least 8 carbon atoms. The weighting may be effected together with other textile processes, e.g., dyeing.  By using halogenated derivatives e.g. the brominated sulphonated amides, increased weighting is obtained.  Besides wools and silk, rabbits', hares', dogs', camels', and cows' hair may be weighted.  In examples: (1) wool yarn, woollen piece goods and merino wool are treated at elevated temperature with aqueous baths containing oleic-N-methylaminoethanesulphonic acid, oleic-N-butylaminoethanesulphonic acid, lauric-N-methylaminoethanesulphonic acid, dichlorstearic - N - methylaminoethanesulphonic acid, trichlorstearic - N - methylaminoethanesulphonic acid, hexachlorstearic - N - methylaminoethanesulphonic acid and tetrachlorstearic-N-methylaminoethanesulphonic acid, in some cases in the presence of sulphuric or formic acid: (2) woollen piece goods are dyed with anthraquinone blue SR extra after being weighted with dichlorstearic-N-methylaminoethanesulphonic acid by addition of the dye to the original bath: (3) wool yarn is dyed with Fast-light yellow 2G and then weighted with hexachlorstearic-N-methylaminoethanesulphonic acid: (4) wool gabardine is dyed and weighted in a bath containing tetrachlorstearic - N - methylaminoethanesulphonic acid, Fast light yellow 2G, Amidonaphthol Red G and Cyananthrol BGA: (5) mackintosh gabardine is dyed and weighted in a bath containing N - hexachlorpalmityl - N - methylaminoethanesulphonic acid, Cyanthrol BGA, Amido yellow E, Amidonaphthol red 6B and sulphuric acid.

Abstract: 1,131,629. Packages. OSCAR MAYER & CO. Inc. 1 April, 1966 [5 April, 1965], No. 14474/66. Heading B8C. An article, e.g. sliced meat, is packaged under vacuum in a preformed container 12 of plastics sheet material, the container being supplied to closing and sealing apparatus, Fig. 5, with its contents, and a plastics closure (14) lying in position above the inverted container. A vertically reciprocable vacuum box 45 is lowered over the partially closed package which is seated in a holder 35 on an intermittently moved conveyer 36. On vacuum being applied, a sealing platen 54 is lowered pneumatically, heaters 55 in the platen activating an adhesive 33 between flanges on the closure 14 and container 12. Before sealing takes place a spring-loaded pressure plate 60 suspended below the platen from a yoke 61 engages within the closure 14 to compress the container contents, annular channels or folds 20, 30, in the closure and container respectively, enabling these members to flex under the pressure. After sealing, the vacuum is cut off and members 45, 54 and 60 are raised before the conveyer advances. The package may be heat-sealed without the use of adhesive. Package.-A wide lateral flange 18 is formed at one side and is apertured to enable the package to be hung up. The container 12 may be of cellulose acetate, nylon, polycarbonate, polystyrene, polypropylene or polyethylene. Each of these materials may be coated with " Saran " (Trade Mark).

In a spot-type disc brake comprising an hydraulic actuator which includes a body member 10, a yoke 11 is slidably supported on the body member and is adapted to engage an indirectly operated friction pad 12, the actuator being operative between the yoke and a directly operated friction pad 13 opposed to the indirectly operated pad 12, a U-shaped member 26 being provided to support tne friction pads for movement towards and away from one another, one limb 27 of the U-shaped member 26 entering a blind hole 28 in the body member 10 and the other limb 29 passing completely through another bore 30 in the body member 10 and having on its free end releasable means in the form of a spring clip 30a for preventing withdrawal of the other limb from its bore. As shown in Fig. 4 the hydraulic actuator includes oppositely movable pistons 14, 15, the former actuating the friction pad 13 directly and the latter acting upon the yoke 11 to urge the indirectly actuated friction pad 12 into engagement with the brake disc. The ingress of dirt between the pistons 14 and 15 and the bore 17 is prevented by rubber boots 40 and 41. The boot 40 of the piston 14 is secured on a nose 42 on the body member 10 by a spring ring 43 and the boot 41 on the piston 15 is secured on a nose 44 on the body member 10 by a spring ring 45. To prevent the boot 41 from being engaged by the inside edge 46 of the yoke 11, the spring ring 45 is made to stand proud of the boot to serve as an abutment for the edge 46 of the yoke. The yoke 11 is also located in the piston 15 by an inwardly extending tongue 22 formed integrally with the yoke and the body member 10 has a pair of longitudinal grooves 20 in which the inside edges of the yoke 11 are guided with clearance. A spring 21 acts between one wall of each groove 20 and the yoke to urge the yoke against the other walls of the groove 20 to avoid a splaying action. Reference has been directed by the Comptroller to Specification 1,075,371.
