Title: Process for separating ª‰-hydroxy-ª‡-amino acids from mixtures of amino acids
IPC: C07D301/32
Filed: 1962-11-13
Abstract: Aliphatic b -hydroxy-a -amino-acids are separated from mixtures containing other amino-acids also, by treating the mixture with a cupric salt to convert the mixture into a mixture of the corresponding complex copper salts, contacting an aqueous solution of the complexes with a strongly basic ion-exchange resin to selectively adsorb the b -hydroxy-a -amino-acid complex copper salt, eluting the complex from the resin with a dilute mineral acid, removing the copper from the solution by treatment with H2S or with a chelating resin, and recovering the b -hydroxy -a -amino-acid from the copper-free solution.  The initial mixture of amino-acids may be naturally occurring mixtures or those produced by fermentation or by the decomposition of naturally occurring materials.  Basic copper carbonate or cupric acetate may be used to form the copper complexes. Suitable resins for the various stages are given.  Threonine and serine are specified acids obtainable by the above process. Specification 959,108 is referred to.

A parison is injection-moulded on an active core rod 26 in injection mould 32 and at the subsequent conditioning station 48, it is cooled and blown to a small extent to counteract shrinkage. At the third, transition station, the active core rod 26 is moved to its inactive position in which it remains for a complete rotation of table 28, passing through cooling chambers 110 or 112, to cool the parison to a temperature conducive to molecular orientation.

Abstract: 1315340 Error detection and correction INTERNATIONAL BUSINESS MACHINES CORP 13 Nov 1970 [24 Dec 1969] 54023/70 Heading G4A In data processing apparatus, errors in data words each including k check bits are detected and/or corrected using k syndrome signals each produced by a respective logic circuit, each check bit being provided to precisely one of the logic circuits, and each data bit to three or a larger odd number of the logic circuits, with substantially equal numbers of data and check bits being provided to each logic circuit. Each logic circuit is an EXCL-OR tree providing a syndrome bit. The syndrome bits produce an "error" signal via an OR gate, and also go to an EXCL-OR gate, the "error"signal being ANDed with the output of the EXCL-OR gate to indicate "single error" and with its inverse to indicate "double error". The syndrome bits and their inverses are combined in AND gates enabled by the "single error" signal to locate the single error (if present) this being corrected using a respective EXCL-OR gate of a row of such gates to which the word is fed in parallel. Each "logic circuit" receives a respective 8-bit byte of the 64 information bits in the word (this choice permits the same hardware to be used for byte parity checking elsewhere in the system), others of the information bits, and a respective one of the 8 check bits provided in the word. The check bits were generated from the information bits for inclusion in the word by EXCL-OR trees similar to the "logic circuits" (less the check bit inputs).
