Title: Improvements in orthophosphoric ester and production thereof
Inventor: CHABRIER PIERRE
IPC: C07F9/09
Filed: 1950-05-26
Abstract: The Specification comprises compounds of the general formula <FORM:0684977/IV (b)/1> where n is an integer not greater than 4 and R1 and R2 are identical or different alkyl groups containing not more than 4 carbon atoms or form a heterocyclic radical with the nitrogen atom, compounds of that general formula wherein the (CH2)n group bears one or more additional hydroxy substituents, and the salts and methyliodides and camphomethylates of such compounds.  Compounds of that formula are prepared by reacting substantially equimolecular proportions of anhydrous orthophosphoric acid and the appropriate tertiaryamino-alcohol, preferably in the presence of phosphorus pentoxide or with azeotropic distillation of water using an entrainer, e.g. xylene. Alternatively a water-soluble tri-metal orthophosphate, e.g. trisodium orthophosphate, is reacted in aqueous medium with the appropriate tertiary amino alkyl halide or a hydrohalide thereof. In place of orthophosphoric acid may be used the polyphosphoric acids described in Helvetica Chimica Acta 1946, 29, 2006.  In examples: (1) orthophosphoric acid and b -diethylaminoethanol are reacted in presence of phosphorus pentoxide to give b -diethylaminoethyl mono-orthophosphate which is converted to its calcium and barium neutral salts and the calcium acid salt; (2) b -diethylaminoethyl chloride and tri-sodium phosphate are reacted to give b -diethylamino-ethyl mono-orthophosphate. Ferrous and copper salts are prepared by reacting the barium or calcium salt with ferrous sulphate and copper sulphate.  Alkali-or alkaline earth metal salts and salts with mercury, bismuth, silver, and zinc are also mentioned.  Similarly obtained are (3) b -N-morpholyl-ethyl mono-orthophosphate; (4) b -N-piperidyl-ethyl mono-orthophosphate; and (5) g -diethylamino-b -hydroxy-propyl mono-orthophosphate and their neutral and acid salts.

Abstract: 1,082,588. Parity checking. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1966 [April 5, 1965], No. 13803/66. Heading G4A. A data processor includes means for performing a parity check on a multi-byte word, each byte of which has an associated parity bit, when at least one data bit has been shifted between bytes or shifted from the word, said means being responsive to byte error signals. A multi-byte word, each byte having a parity bit, can be transferred from a first register to a second register with or without shift. In either case, a parity check is performed on each byte position of the second register (ignoring any change in byte boundaries) to produce respective error signals, which are fed to an OR gate and to an exclusive-or tree. A further input to the tree is " one " if the number of " one " bits shifted out (in the case of shift) is odd. A correct error signal is obtained from the OR gate or the tree in the case of no shift and shift respectively. Shift during multiplication and division is mentioned.
