Title: Production of adenine derivatives
IPC: C07F9/6561
Filed: 1975-04-09
Abstract: 1510534 Derivatives of adenine and of adenine ring-containing compounds SNAMPROGETTI SpA 9 April 1975 [30 April 1974] 14711/75 Headings C2P and C2C The invention comprises a derivative of a compound containing the ring structure characteristic of adenine in which one of the H atoms in the 6-amino group of the adenine ring system is substituted by a group having the formula -CH 2 -CH(OH)-(CH 2 ) n -COOR in which R is H, alkyl, cycloalkyl, aryl or aralkyl and n is an integer from 1 to 4. The adhesive ring- containing compound may be adenine, adenosine, nicotinamide - adenine - di - nucleotide (NAD), NAD - phosphate, adenosine monophosphate, cyclic adenosine monophosphosphate, and adenosine di- and tri-phosphate. The products may be obtained by reacting adenine or said adenine compound with a compound of the formula wherein R and n are as defined above in the presence of a source of hydrogen ions, e.g. perchloric acid, to form the 1-substituted derivative of said adenine compound and then affecting rearrangement of the 1-substituted derivative to the corresponding 6-substituted amino purine compound. The first stage of the process is preferably carried at 0 to 50 C. in the presence of water, a water-miscible organic solvent or a mixture of water and such organic solvent and the pH is preferably maintained at about 6 by adding perchloric acid in which case the 1- substituted derivative has the following type structure The rearrangement step is suitably effected at pH 7 to 11À5 and at from 5 to 80 C. When the starting adenine derivative is one containing a nicotinamide nucleus, it is preferable to effect a chemical reduction of the 1-substituted intermediate derivative before the rearrangement and when the process is applied to NAD the rearrangement product in reduced form may be submitted to enzymatic reoxidation with a dehydrogenase to yield the desired 6-substituted derivative of NAD. Examples are given in which the adenine moiety corresponds to NAD, n is 1 and R is H and CH 3  respectively. The products especially those derived from NAD, after being covalently linked to a macromolecule, are useful in affinity chromatography and as non-diffusing co-enzymes in enzyme systems wherein an enzyme is incorporated in an insoluble structure impervious to macromolecules, e.g. in polyacrylamide gel or in microcapsules formed of a polymer. 3,4 - Epoxybutanoic acid and its methyl ester are obtained by the reaction of an aqueous solution of peracetic acid on 3-butenoic acid dissolved in CH 2 Cl 2  and on methyl-3-butenoate in diethyl ether respectively.

Title: Method for preventing the formation of haze in fermented beverages
IPC: C12H1/056
Filed: 1958-05-08
Abstract: The shelf-life of a fermented beverage is improved by preventing the formation of both chill-haze and oxidation-haze, which is effected by removing non-protein compounds such as leucoanthocyanins (anthocyanogens) in solution in the beverage, completely or in part by adsorption on a powdered insoluble polyamide resin of chemical structure exemplified either by (1) polyhexamethylene adipamide or by (2) polye -caprolactam. Examples are directed to the treatment of pale ale, cider and white wine.  According to an example, 5 gallons of pale ale was filtered through 15 g. of a powdered polyamide conforming to structure (1) above in a stainless steel filter-tube bounded at each end by filter sheets clamped at their peripheries between stainless steel flanges.  The filtration occupied 2.5 hours and removed 55% of the leucoanthocyanins of the beer; the shelf-life was extended sixfold.

Title: Cryogenic surgical apparatus
IPC: A61B18/02
Filed: 1973-03-29
Abstract: 1422445 Cryogenic instruments BENDIX CORP 29 March 1973 [29 March 1972] 15265/ 73 Heading A5R [Also in Divisions B1 and B2] An apparatus, Figure 4, for converting a gas into a liquid for use in cryogenic surgery, comprises a hollow sleeve 76 having a closed end 80 and an open end, within which sleeve is located an elongated core, one end 30 of which defines, with the closed end 80 of the sleeve, a fixed volume chamber 86, a coiled tube 46 surrounding the core and having an exit reach 72 within the chamber 86, the annular space also including thermally conductive means in thermal contact with the coiled tube; the arrangement being such that, in use, gas under pressure passing through the coiled tube 46 is throttled as it enters the chamber 86 through the exit reach 72, thereby being cooled to between -80C and -250C and liquified, an exit path for the gas from the chamber being provided between the coils of tube 46. The core and sleeve 76 are held by a member 32 having radial fingers 40. Gas, e.g. nitrogen, is supplied from a source 10 by way of a valve 12, a pressure gauge 18, and a drier 20 to the tube 46 by way of an entrance reach 48. At the other end of the tube the gas passes to the exit reach 72 and emerges, cooled, from a nozzle 98, into the chamber 86. The exit from the chamber is through the space between the convolutions of the tube 46. Conductive granular particles 99 fill the space 100. The cooled gas passing round the tube 46 pre-cools the gas within the tube, so that cumulative cooling takes place until the gas liquifies. Nitrogen gas is preferred, and liquifies at about -196C, cooling the end 80 of the sleeve sufficiently for it to be used for cryogenic surgery. The temperature of chamber 86 is kept within a given range by a regulator using bimetallic strips [see Divisions B-B2]. The liquid may be absorbed by material in the chamber 86, so that the apparatus may be turned away from the vertical. An insulating coating 92 enables the instrument to be hand-held to operate with the rounded end 80 of sleeve 76.
