Title: Process for the manufacture of new condensation products
IPC: E01C5/22
Filed: 1932-05-13
Abstract: Aminohydroxy fatty acids, esters and amides; pyrazolones; pyrimidines.--Glycidic acid, its esters or amide or their alkyl, aralkyl or aryl substitution products are condensed with amines at elevated temperatures under substantially anhydrous conditions. When the amine contains one reactive amino group, the condensation takes the course:-- <FORM:0389310/IV/1> in which R represents hydrogen, alkyl, aralkyl or aryl and Y signifies either OR or NRR.  The use of an amine R -- NH -- X -- NH -- R containing two reactive amino groups, X representing a divalent residue such as an alkylene group or CO or being absent altogether, leads to the formation of a product of the formula:--  <FORM:0389310/IV/2> Alkaline condensing agents, e.g. sodium ethoxide or sodamide, are advantageously present. Examples are given of the condensation of (1) b b -dimethylglycidic acid, its amide or ethyl ester with aniline or monomethylaniline; the product comprises a -hydroxy-b -anilido (or methylanilido) -isovaleric acid, ester or amide; (2) b b -dimethylglycidic acid amide with phenetidine to give a -hydroxy-b -phenetido-isovaleric acid amide; (3) b b -dimethylglycidic acid amide with 1-phenyl-2 : 3-dimethyl-4-amino-5-pyrazolone and 2-aminopyridine; (4) b b -dimethylglycidic acid diethylamide with 6-methoxy-8-aminoquinoline; the product consists of b -(6-methoxy-8-aminoquinoline)-a -oxyisovaleric acid diethylamide; (5) b -phenyl-a -methylglycidic acid with methylamine to form b -phenyl-b  - methylamino - a  - hydroxy - a  - methylpropionic acid methylamide; (6) b b -dimethylglycidic acid ethyl ester or amide with phenylhydrazine, yielding 1 - phenyl - 3 : 3 - dimethyl - 4 - hydroxy - 3 : 4 - dihydro - 5 - pyrazolone; (7) b b  - dimethylglycidic acid amide with urea to give 4 : 4-dimethyl - 2 : 6 - dioxo - 5 - hydroxyhexahydropyrimidine; (8) b b -dimethylglycidic acid amide with o-phenylenediamine or ethylenediamine.  Specification 226,686, [Class 2 (iii), Dyes &c.], is referred to.  The Specification as open to inspection under Sect. 91 also describes the condensation of dimethylglycidic acid amide with sodium arsanilate.  This subject-matter does not appear in the Specification as accepted. Glycidic acid amides are prepared by the action of ammonia on the esters formed by the condensation of ketones and a -halogen fatty acid esters in presence of sodamide.

Abstract: 1,106,893. Magnetic recording. ELECTRIC & MUSICAL INDUSTRIES Ltd. 7 April, 1965 [7 April, 1964], No. 14218/64. Heading G5B. [Also in Division H3] In a magnetic recording circuit an amplifier has a winding of the magnetic recording head 1, connected in a negative feedback path from an output terminal of the amplifier so as to feed back a signal proportional to the current flowing through the recording head. The amount of negative feedback is such that the output impedance of the amplifier is increased so as to maintain the current through the load constant as the frequency is varied. Input signals to C1 are fed to transistor VT1 and via a frequency compensating network R4, R5, C3, which boosts the high frequencies, to transistor VT2 which is directly coupled to the output transistor VT3 of opposite conductivity type. D.C. negative feedback is applied from the output by resistors R10, B11 to the base of VT2 and positive feedback is applied via capacitor C4. A.C. negative feedback is applied through F1. The secondary winding 2 of a bias erase output transformer is connected to the recording head 1 and a bias frequency filter F1 prevents bias signals from reaching the base of VT2. Transistors VT2 and VT3 need not be of a complementary type.
