Abstract: Substituted pteridines having in at least one tautomeric form the formula <FORM:0657903/IV (b)/1> wherein R is an aromatic radical, are prepared by mixing the following: (i) 2 : 4 : 5 : 6-tetraaminopyrimidine or a tautomer thereof or an acid salt thereof; (ii) an alpha, beta-dihalopropionaldehyde or an acetal thereof, or a 1 : 1 : 3-trichloroacetone; (iii) a primary aromatic amine.  Reactant (i) and (ii) may first be mixed and the reaction product thereof mixed with reactant (iii), or reactants (ii) and (iii) may be mixed and the reaction product thereof mixed with reactant (i).  The process may be carried out at a temperature from about 0 DEG  to 100 DEG  C. and/or at a pH between about 1.5 to 6.  The reaction may be effected in the presence of water or other inert solvent, a number of which are given.  Dihalopropionaldehydes that may be used are alpha, beta-dichloro and dibromo propionaldehydes, and trihaloacetones that may be used are the 1,1,3-trichloro and tribromo acetones.  The primary aromatic amines mentioned are the o, m and p-aminobenzoic acid and the salts, esters and amides thereof.  Preferred aromatic amines are the amino acid amides of p-aminobenzoic acid, e.g. p-aminobenzoyl glutamic acid and polypeptides thereof, e.g. p-aminobenzoyl-glutamylglutamic acid 3,5-dibromo-4-aminobenzoylglutamic acid and p-aminobenzoyldiglutamyl glutamic acid and others move up of one or more of the various amino acids, e.g. p - aminobenzoylglutamylglycylglutamic acid.  Other amino acids mentioned from which the amides of p-aminobenzoic acid may be derived are glycine, aspartic acid, leucine, serine, sarcosine, phenylalanine, alanine, isovaline and cysteine.  The amino acids may be natural or synthetic and may be in any of the d, l or d-l forms, while free carboxyl groups may be esterified, neutralized or converted into an amide, e.g. ethyl-p-aminobenzoylgamma-glutamyl gamma-glutamyl glutamate may be used.  Other amides mentioned are p-amino-benzamide and amides formed by the reaction of aminobenzoic acid and ethylamine, ethanolamine, dodecylamine, ethylhexylamine, benzylamine, morpholine, aniline and 2-aminopyrimidine.  Oxidizing agents may be added to the reaction mixture to prevent the formation of the corresponding dihydropteridines, e.g. those having an oxidation-reduction potential of about -0.49 to 1.42 volts, e.g. iodine, chlorine, potassium bromate, benzoquinone, manganese dioxide, sodium dichromate and ferric chloride.  A number of detailed examples are given.  N-(p-aminobenzoyl)-alanine is prepared by hydrogenating N-(p-nitrobenzoyl)-alanine in alcohol in the presence of palladium on activated charcoal.  The corresponding N-(p-aminobenzoyl) substituted phenylalanine, valine and serine are prepared by a similar method.

Title: Improvements in or relating to automatic regulating devices for the fuel injection pumps of internal combustion engines
IPC: F02D9/00
Filed: 1945-09-27
Abstract: 600,636. Regulating. FABIAN, H. E. Sept. 27, 1945, No. 25096. Convention date, Oct. 5, 1944. [Class 7 (vi)] In an engine having an air throttle 14 operated conjointly with the control rod 18 of a fuel injection pump 1, automatic correction of the air-fuel mixture is obtained under varying load by a compensator operated as a function of the engine speed. In Fig. 1, a centrifugal governor 2 controls an eccentricallypivoted lever 6 connected to an eccentric pivot 10 supporting a compensating lever 11 connected to the throttle 14 and to the control rod 18 through a lever 17 pivoted at 17a and sliding in a knuckle joint 16. Opening of the throttle 14 causes the rod 18 to move in the direction F to increase the fuel supply, but as the speed rises the governor 2 rotates lever 6, causing the lever 11 to rotate about the point 20 and move rod 18 in the opposite direction to correct the fuel supply in accordance with increased pump efficiency at higher speeds. The positioning of the joint 16 arranges that the correction increases progressively with opening of the throttle 14. A capsule 22 actuating a lever 21 further adjusts the fuel supply for varying atmospheric temperature and pressure, and manual operation of a button 31 connected to an abutment 32 rotates the lever 21 to enrich the mixture at starting. In a modification, the centrifugal governor is replaced by a spring-controlled piston actuated by hydraulic pressure supplied by an enginedriven pump.
