Abstract: The present invention provides processes for synthesizing lysine based compounds of the formula; , wherein R1 may be, for example, (HO)2P(O)—, (NaO)2P(O)—, wherein X may be, for example, NH2, Y may be H, F, Cl, or Br, and wherein n, X?, Y?, R2, R3, R4, R5 and R6 are as defined herein.

Abstract: This invention is selected novel chiral (essentially pure) alpha-amino phosphonates, process for the preparation which is a catalytic asymmetric hydrogenation of olefins and novel intermediates therefor. The alpha-amino phosphonates are useful as antibiotics and/or as intermediates in the preparation of phosphorus-containing analogs of peptides, i.e., phosphonopeptides or pseudopeptides having known uses, such as in antibiotics, antibiotic enhancers, or enzyme inhibitors.

Abstract: A urethane reaction product, derived from an alkoxylated diorgano phosphorodithioate and an isocyanate, specifically, toluenediisocyanate and hexamethylene diisocyanate, is a multifunctional antiwear and antioxidant additive for lubricants. The isocyanate groups of the reaction product are substantially converted to urethane and/or urea groups through post reaction with active hydrogen compounds such as dibutylamine, bis(2-hydroxethyl) cocoamine and alcohols such as 2-propanol.

Abstract: Ester and amide derivatives of N-(((alkoxy-(alkylthio)phosphinyl)amino)carbonyl)amino)alkanecarboxylic acids of the formula: ##STR1## (wherein R.sup.2 represents an alkyl group containing a carboxylic acid ester or amide moiety) were prepared by the reaction of O,S-dialkyl phosphoroisocyanatidothioates and ester and amide derivatives of naturally occurring and synthetic aminoacids and were found to be effective plant systemic and contact insecticides. Ethyl N-(((methoxy(methylthio)phosphinyl)amino)-carbonyl)methioninate, for example, were prepared from O,S-dimethyl phosphoroisocyanatidothioate and ethyl methioninate and found to control aster leafhoppers when applied to rice plants.

Abstract: Herbicidal compounds of formula: ##STR1## in which R.sup.1 denotes an optionally halogenated alkyl radical containing from 1 to 4 carbon atoms,R denotes the hydrogen atom or an alkyl group containing from 1 to 4 carbon atoms,R.sup.2 denotes the hydrogen atom or R21,R.sup.21 and R.sup.3 denote optionally substituted aryl radicals,R.sup.4 denotes a hydrogen atom or a hydrogenolysable group R.sup.8,and the agriculturally acceptable salts of these compounds.

Abstract: A system for the automatic correction of convergence and gray scale in color television employs light sensors, either singly or in an array, on the beam landing face of a cathode ray tube or on the screen of a projection receiver. The sensors can be placed in the overscanned area of the raster, such that they are outside the normal viewing area, or in the viewing area if the sensors are made sufficiently small. In the vicinity of a sensor, two of the three cathode ray tubes or electron guns are blanked. As the light beam, in the case of a projection system, crosses the sensor, an output is produced. This output is processed to obtain accurate timing characteristics. Since the position of the sensor is known in terms of counts in both the vertical and horizontal directions, error signals can be developed by comparing the timing of the sensor output with the proper count.
