Title: A method for preparing condiments containing 5'-nucleotides from yeasts
IPC: C12P19/30
Filed: 1966-03-15
Abstract: 1,144,793. Nucleotide-containing condiments from yeast. TAKEDA CHEMICAL INDUSTRIES Ltd. 15 March, 1966 [15 March, 1965], No. 11378/66. Heading C2C. [Also in Division A2] Condiments containing 5<SP>1</SP>-nucleotides are prepared from yeast by treatment, firstly with an enzymic system (A) produced by incubating micro-organisms of the genus Trametes and capable of hydrolysing nucleic acid into 51- nucleotides in an aqueous medium at a pH of about 8-11, and subsequently with another enzymic system (B) produced from the same genus and capable of solubilizing organic materials in an aqueous medium at a pH of about 2À5-7. Any kind of yeast, such as brewery, bakery, bottom, top or wine yeast, may be used. The micro-organisms are preferably incubated in a liquid medium on an industrial scale and may be cultured under shaken or stationary conditions, or with aeration. Submerged cultivation may also be used. The culture medium should contain carbon and nitrogen sources which are assimilable by the micro-organisms, e.g. starch, dextrin, ammonium salts and nitrates &c. as well as cornsteep liquor, peptones and meat extract. Mineral salts such as calcium, magnesium, potassium and zinc salts &c. may also be added. The micro-organisms are preferably incubated at a temperature of 15-35‹ C. at a pH of 3-6. The initial concentration of yeast is preferably 5-30% (wt./vol.) of the total reaction system. The liquid portion obtained from the enzymic treatments above is collected by centrifuging or filtration and contains 5<SP>1</SP>-nucleotides including adenylic, guanylic, inosinic, cytidylic and uridylic acids. The liquid may be concentrated or dried to give a powder. If undesirable inorganic materials are present, they can be removed by using ion exchange resins. Enzymic system A is mainly accumulated in the solid portion of the culture broth and may be extracted by surface active agents, supersonic waves or other known means. Enzymic system B is usually contained in the culture filtrate and may be recovered, e.g. by precipitation or centrifuging.

Title: Improved vehicle disc brake
IPC: F16D65/02

Abstract: 706,789. Disc brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. April 17, 1952 [May 16, 1951], No. 11397/51. Class 103(1) A disc type brake comprises a braking member having a pair of co-axial discs spaced axially apart and connected together at one periphery, slots adjacent the periphery to permit the passage of air, means for connecting said member with a rotatable member, a non-rotatable housing located between said discs and occupying a minor portion of their periphery, and pads of friction material axially slidable in said housing to frictionally engage the adjacent sides of said discs by fluid pressure operated means. A pair of co-axial steel discs 1 and 2, shown in Fig. 2, which is a sectional view through A-A of Fig. 1, are spaced axially apart and connected together at their outer peripheries by axially-extending aluminium fins 3. The inner periphery of one of the said discs is provided integrally with a radially extending annular flange 4 which is provided with a plurality of holes 5. whereby the braking member may be secured to a rotatable part of the wheel assembly. The non- rotatable part of the wheel assembly is provided with an annular flange 6 which has secured to it an arcuate housing 7 which has three equispaced bores 9 extending axially through the housing in which six circular friction pads 11, backed by plunger members 10, are provided. When brakes are applied, fluid pressure is forced from a conventional braking system to the space between the plunger members 10 thereby forcing the pads into frictional contact with the inside walls of the revolving braking member. Slots are provided adjacent the periphery to permit the passage of air for cooling purposes and may be positioned as shown in Fig. 2 or provided in the side walls of discs 1 and 2. In another embodiment of the invention the braking member comprises two pairs of co-axial discs connected together by axially extending fins. The bores 9, instead of each being provided, as described, with a pair of oppositely acting plunger members and associated friction pads, may, instead, each be closed at one end and provided with a single friction pad, almost as long as the thickness of the housing, and backed by a plunger member. Preferably there are an 'even number of bores and adjacent friction pads act in opposite directions so that even less frequent renewal is necessary than when two pads are located in the same bore.

Title: Processes for the production of high molecular guanamines, and their water-soluble derivatives, and the resulting products
IPC: C07D251/18
Filed: 1942-08-17
Abstract: High molecular guanamines are prepared by heating to above 170 DEG C. acylbiguanides containing at least 8 carbon atoms in the acyl residue.  The acylbiguanide may be prepared by acylating dicyanodiamide with a high molecular aliphatic, alicyclic or hydroaromatic acid, and treating with ammonia, or organic bases or salts, in either order, whereby the production of the acyl-biguanide and the formation of the guanamine, including heating to above 170 DEG  C., is carried out without separation of the acylbiguanide. Alkylation or aralkylation may be effected before or after cyclisation.  The products may be exhaustively alkylated, hydroxyalkylated or sulphonated, the water soluble derivatives being used as emulsifiers, washing agents, for softening textiles, levelling and stripping agents, and washing, dispersing and wetting agents.  Palm nut, stearic, palmitic, oleic, Behenic, resin, cotton seed oil, train oil, myristic, fencholic and campholic acid or mixtures may be used.  In examples, stearoyl-xylyl-biguanide, prepared by heating stearic acid and dicyanodiamide and reacting the stearoylcyanoguanidine with a xylidine mixture, is heated for 12 hours to 190-200 DEG  C. The compound obtained is dissolved in sulphuric acid and sulphonated with oleum.  Lauroyl - N - isopropylxylyl - biguanide, obtained by heating lauroyl-cyanoguanide with a mono-propylated xylidine mixture, is heated to 180-220 DEG , and the product sulphonated.  Stearoyl-hydroxyethyl-biguanide, prepared by reaction of dicyano-diamide and stearic acid chloride in presence of monoethanolamine, is heated to 190-210 DEG  and the product treated with dimethyl sulphate to methylate it and form the quaternary compound.  Stearoylphenyl biguanide, from dicyandiamide, stearic acid and aniline, is heated to 200 DEG  C., and the product is methylated with dimethyl sulphate and then sulphonated. Methylated stearoylcyanoguanidine is heated with methyl aniline to 130-140 DEG  C. in a carbon dioxide atmosphere and then to 190-210 DEG  C. until water separation has finished, and the product is sulphonated.  Other biguanides which may be used are lauroyl-o-tolyl-, lauroyl-p-methoxy-phenyl-, lauroyl-o-, m-, or p - ethoxyphenyl, lauroyl - tri - aminotriethylene, stearoyl-N-methyl-phenyl, stearoyl-m-xylyl, and stearoyl-aminoethylene biguanide or their partially alkylated derivatives, and lauroyl dihydroxyethyl biguanide.  Specification 546,027 is referred to.
