Title: Improvements in and relating to the manufacture of hollow articles of rubber or other plastic substance
IPC: B29D22/00
Filed: 1921-04-05
Abstract: 182,564. Spencer, Moulton, & Co., Ltd., G., and Panzetta, F. M. April 5, 1921. Sheet-cutting machines; rolling-machines; feeding; moulding india-rubber balls and hollowware.-Hollow articles of rubber &c. are moulded by leading the material in sheet form on to rotating wheels having moulds into which the material is pressed, the blanks so formed being united and cut out continuously. Two sheets 57, Fig. 7, are directed by rollers 58 on to rotating wheels 3, 4 and are held in position by projections. Endless belts 45, 53 carrying dies 46, 54 of which the dies 54 are provided with recesses 55 for the " inflation blobs," are mounted in frames 39, 49, adapted to rock in shafts 40, 38 so as to cooperate with the wheels 3, 4, and force the material into the moulds. The latter, Fig. 10, have their bottoms covered with gauze 75 held by domeshaped washers 76 secured to the tubes 73. These tubes connect with passages 60, 61 70, Fig. 7, in the axles of the wheels so that without operation of valves the moulds are successively evacuated and filled with compressed air so as to suck in the material and then eject the blanks. The sheets, after treatment with cement by means of rollers 77, and after, if necessary, the lower moulds have been supplied with chemical tablets 84 from the delivery apparatus, Fig. 11, are pressed between the wheels so as to unite the blanks and cut them out by means of cutting edges on the moulds. For this purpose the mould wheels are geared together by spur-wheels 5, 6, so as tc rotate freely when separate but to come tc rest when the upper wheel, adjustably mounted in springs, is brought into contact with the lower by means of toggle-links 33, 34 actuated by the two-throw crank 12 through its upper crank-pin 27 and levers 28, 30. The lower crank-pin 13 connects the crank through levers 15, 16 to the ratchet hook 18 which engages projections 19 in the lower spur-wheel 6 and thus rotates it step by step. Correct alignment and locking of the moulds is obtained by blade springs 23 fixed by collars 24 to the shafts 7, 8 and carrying studs 25 which engage recesses 26 in the wheels.
Patent GB-561645-A (GB)
Title: Improvements in or relating to gel-forming polymerization products
IPC: C08F36/04
Filed: 1942-07-20
Abstract: A material capable of forming a stable gel with water is prepared by reacting a conjugated diolefine with the cis form of an unsaturated dibasic acid or acid ester or anhydride thereof, treating the resulting product with an oxygenated organic solvent to remove low molecular weight products and treating the residual high molecular weight products with an aqueous solution of a basic metal compound or an onium base to form a salt gel, which is preferably washed free from soluble material and dried by heating in vacuo.  Olefines specified are butadiene 1,3, piperylene, isoprene, 1,2-, 1,3-, 1,4- and 2,3-dimethylbutadiene 1,3, the trimethylbutadienes, chloroprene, cyclopentadiene 1,3 and cyclohexadiene-1,3.  The acids may be maleic or citraconic acid. The condensation-polymerization reaction may be effected at room temperatures or higher, e.g. 40-53 DEG  C., preferably in the liquid phase.  The basic metal compound may be alkali or alkaline earth metal oxides, hydroxides, or carbonates. Salts of other metals may be prepared by double decomposition of the alkali or alkaline earth metal salt with an aqueous solution of aluminium nitrate, silver nitrate or nickel chloride.  The products may be used as protective colloids in the preparation of gels, emulsions, suspensoids and foams.  In the example, piperylene and a solution of maleic anhydride in benzene are mixed in a flask fitted with a reflux condenser.  After reaction had ceased, alcohol was added to the mixture and the high molecular weight products (10-15 per cent) were filtered off and washed with hot water.  The product was heated on a steam bath with sodium hydroxide until a stiff gel was formed which was washed with water and dried in vacuo.

Abstract: 1307041 Improved fermentations involving charcoal MOBIL OIL CORP 21 April 1971 [27 July 1970 2 Sept 1970] 10361/71 Heading C6F In a fermentation process in which a microorganism, a source of carbon for the growth of the micro-organism, mineral nutrients and water constituting a fermentation broth are retained in a fermentation vessel for a given residence time, at least a portion of the fermentation broth (including the micro-organism) is contacted during the residence time with charcoal. The fermentation broth may be passed through a bed of charcoal. Alternatively, the charcoal may be confined within a foraminous container which is maintained in the body of broth. The particles of charcoal should be sufficiently large to avoid filtration of the micro-organism cells e.g. between 4 and 8 mesh in the U. S. Standard Sieve Series, and not smaller than 10 mesh. At least 1 gram (even 10 grams or more) of charcoal is employed for each litre of fermentation broth every 24 hours. Many species of micro-organism are particularly mentioned. Carbon sources include specified hydrocarbons, oxygenated hydrocarbons, carbohydrates and cellulosic materials e.g. garbage or waste products from paper manufacture. Air is injected into the broth (where required at gauge pressure in the range of 6 to 225 mm. Hg. Injection rates, dilution ratios and superficial velocities for the air are mentioned. An example relates to a continuous cultivation of Pichia yeast on n-hexadecane. Enhanced cell productivities, conversion efficiencies and protein contents were achieved when the fermentation broth was circulated through a bed of wood charcoal.
