Title: Fire alarm monitor for regenerative air preheater - uses paired electrical conductors separated by a semi-conductor
IPC: F28F27/00
Filed: 1974-12-02
Abstract: The cylindrical air preheater encloses a cellular core with series of ducts on the outer side. Pairs of electrical conductors in parallel are fitted around circular paths between adjacent hot and cold heat end faces. The conductors are separated along their length by a semiconductor material with predetermined characteristics. These are designed to provide a high electrical resistance at normal working temps. with a sudden drop in resistivity at a danger threshold temp. The conductors then pass a pulse of electricity which triggers the fire alarm. The design is economical and monitors all areas of the chamber where combustible waste particles can be deposited during operation.

Abstract: 1501512 Recovering micro-organisms from hydrocarbon fermentations PETROLCHEMISCHES KOMBINAT SCHWEDT VEB 16 April 1975 [29 April 1974] 15710/75  Heading C6F A process for the separation of micro-organisms e.g. yeast from a culture medium in the aerobic fermentation of the micro-organisms in liquid hydrocarbons in the presence of an aqueous nutrient solution involves emulsifying the culture medium and adding to the emulsion 0À1 to 5À0 g  per kg of a separating agent which is a phosphatidic hydrocarbon extract obtained where microorganisms cultivated in a liquid hydrocarbon distillate are purified by extraction (see below), the micro-organisms being removed by phase separation after about 3 minutes. The biomass is recovered from the aqueous phase and dried, and the dried biomass is further purified by extraction with a solvent in order to remove any petroleum distillate still present. From the resulting extract after removal of the solvent by distillation or acetone precipitation there is obtained the solvent-free phosphatidic hydrocarbon extract for use as the separating agent in the process. In an Example, the phosphatidic hydrocarbon extract consisted of a 1% solution in petroleum distillate of 18À0% phosphatides of the lecithin type, 17À0% phosphatides of the kephalin type, 32À4% triglycerides, diglycerides, monoglycerides and free fatty acids, 0À6% steatin and ubiquinone, and 32À0% hydrocarbons.

Title: Prolonged release amino cpds. prodn. - by reacting (meth)acrylic acid ester or amide reaction products with amino acids and copolymerizing
IPC: C08G69/10
Filed: 1975-06-16
Abstract: New process converts active substance with an NH2 group into polymeric form, intended for prolonged release of the active substance by enzymatic cleavage. A substd. amide or ester of acrylic or methacrylic acid having a chain of is not 3 atoms in the side-chain terminating in the C-atom of the carboxyl group is condensed with the alpha-amino group of an L-amino acid. The active cpd. is then bound via its NH2 group to the carboxyl group of the amino acid. The resulting monomer is copolymerized with a hydrophilic monomer based on N-alkyl-(meth)acrylamide, or N, N-dialkylacrylamide ('alkyl' being 1-6C). The hydrophilic monomer may contain 1-3 OH groups or glycol (meth)acrylate ('glycol' being ethylene, propylene, butylene, diethylene or triethylene glycol, or homologous 2-6C polyglycols). The copolymerization can be carried out in the presence of smaller amts. of further monomers, which can act as crosslinking agents. The polymers permit regulation of the physical and biological behaviour of the active substance by variation of the character and molecular weight of the polymeric carrier. Rate of enzymatic cleavage can also be regulated by the length of the side-chain. The active substance is protected against premature excretion and against inactivation (e.g. histamine can be protected against the action of histaminase). Examples of L amino acids which can be used are phenylalanine, tyrosine, alanine, citrulline and ornithine. In an example, a copolymer contg. 97.6 mol. % N-(2-hydroxypropyl)-methacrylamide and 2.4 mol. % N-methacryloylglycylphenylalanyl nitroanilide is produced by direct copolymerization. The copolymer is used as a substrate for enzymatic cleavage by chymotrypsin.

Title: Breaking synthetic filaments into small fibres using two roller nips - of which line of action is varied to exert breaking force
IPC: D01G1/08
Filed: 1975-06-16
Abstract: Synthetic filaments of long fibres are advanced through a breaking zone defined between two roller nips arranged symmetrically, each nip comprising an upper presser roll covered with an elastic matl. e.g. rubber, and two lower rolls having smooth or grooved surface and acting on the surface of the pressor roll. One lower roll is of smaller diameter and being positioned closest to the breaking zone. The presser oll is mounted on a presser assembly which continuously forces the presser roll against the lower rolls the pressing force being variable so that an even pressure is applied to both lower rolls, or so that the pressure on one lower roll is greater than on the other roll. The presser assembly acts also so that the line of action of the force applied by the roller nips to the synthetic filaments or fibres in variable to produce a breaking force on the filaments or fibres. The method is used for breaking up synthetic fibres so that they can be treated using conventional wool fibre processes.

Title: Fluidised bed air operated separator - separating bulk product into fractions, has two chambers connected by pneumatic transport duct
IPC: B03B4/06
Filed: 1975-06-17
Abstract: A fluidised bed separator using air to separate a bulk product into sevral fractions and having two chambers, incorporates a pneumatic transport duct connecting the two chambers. The chambers have porous floors, through which the air is blown, and product outlets. The coarsest fraction is taken off from the first chamber. The other fractions go through the pneumatic transport duct to the second chamber. The second chamber has a short section from which a separate air supply separates very fine material from the fine product from that chamber and returns it to the top of the chamber. A cyclone separates very fine product from the air stream leaving the plant. In alternative forms, the incoming air may be conditioned, e.g. by a heat exchanger, the porous floor may be vibrated or inclined, its porosity may be varied to suit the product, the pneumatic transport system may include an injection type. The separator gives a better sepn. and is simpler to construct than existing separators, because the fluidisation is good in both chambers, and each section is very homogeneous.
