Patent GB-892083-A (GB)
Title: Resin absorbate and use for purification
IPC: A23K20/195
Filed: 1960-11-11
Abstract: An antibiotic resin adsorbate comprises the reaction product of bacitracin and a particulate cross-linked cation-exchange resin consisting of a sulphonated styrene/divinyl benzene copolymer, or a monovalent cation salt thereof, e.g. a sodium, potassium or ammonium salt.  In examples bacitracin sulphate is reacted with a sodium salt of the resin.  The adsorbate finds application as a feed supplement in swine and poultry feeds.ALSO:In a process for the isolation and purification of bacitracin from aqueous solution, the pH of the solution is adjusted to from 3 to 7 (e.g. with sulphuric acid) and the solution is then contacted with a salt of a sulphonated copolymer of styrene with divinyl benzene, to cause adsorption of the bacitracin on the copolymer.  Elution of the bacitracin from the adsorbate obtained, may be effected with an aqueous base having a pH of 7.5 to 8.5, e.g. with 2% sodium carbonate solution.  In examples bacitracin sulphate is contacted with a sodium salt of the sulphonated copolymer.ALSO:An antibiotic feed supplement comprises a feed acceptable diluent together with an adsorbate of bacitracin on a salt of a sulphonated styrene/divinyl benzene copolymer, said adsorbate being present in from 5 to 50 grams of bacitracin activity per pound of supplement.  The adsorbates may be used in conjunction with other antibiotic or therapeutic agents such as penicillin, oxytetracycline, chlortetracyline, tetracycline, phenyl arsonic acid or sulphaquinoxaline and may be blended with grains, fish meal, bone meal, soybean meal, limestone, vitamins and amino acid ingredients. In examples specified feed ingredients are corn, soybean meal, corn gluten meal, alfalfa meal, animal fat, fish meal, corn solubles, whey, brewers' yeast, iodized salt, calcium carbonate, calcium phosphate, Delamix, methionine, Vitamins A, B12 and D3, riboflavin, calcium pantothenate, niacin, choline chloride, diphenylphenylenediamine, skim milk, sucrose, mineral mix and saccharin.  The feed supplements are of particular use for swine and poultry feeds.

Title: Method and means for quantitative analysis of sulphuric acid-containing gases
IPC: G01N27/06
Filed: 1975-09-23
Abstract: 1516896 Analyzing sulphuric acid containing gases CABOT CORP 23 Sept 1975 [30 Sept 1974] 38880/75 Heading G1N Sulphuric acid contained as an aerosol or vapour in a carrier gas is determined by contacting the gas with a substantial exposed surface of a known quantity of water, collecting the resulting solution and determining its conductivity and temperature. The gas-liquid contact preferably occurs in a porous filter medium of inert, water wettable, material which may be stainless steel, ceramic, glass or synthetic polymer. Interfering materials in the gas may be removed before measurement by filtration of the gas followed by desorption of the sulphuric acid deposited on the filter by a moderately heated, inert, purge gas. As shown, the apparatus comprises a chamber 1 divided horizontally by sintered glass filter 7. A conductivity cell 40 and thermistor 45 are mounted in arm 5 extending downwards from chamber 1 and water supply is via pipe 23. Various other inlets and outlets with associated valves are connected as shown. In operation, the cell is calibrated by solution via tube 34 filling arm 5 to at least the level of thermistor 45. Drain 36 is then opened and the cell is flushed by water via 23 and compressed gas via 13. A small (known) amount of de-ionized water is introduced through 23 to wet the filter. Valves 31 and 19 are opened and a known amount of the sulphuric acid gas is passed through the filter. The absorbed acid is washed into arm 5 by a measured amount of water from pipe 23, assisted by gas pressure via 13 venting along 32. The conductivity is then measured. The conductivity cell and thermistor are connected into two arms of a self-nulling Wheatstone Bridge.
