Abstract: 300,219. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 7, 1927. Anthraquinone vat dyes are obtained by heating anthrones having a further ring attached in the m.s- and 1-positions, at least in the latter place by means of a nitrogen atom, and halogenated in the 2-position, with metals, in presence or absence of a solvent. 2-Halogen-anthrapyridones, anthrapyrimidones. anthrapyrimidines, and -coeramidonines are mentioned; it is sometimes advantageous to employ acyl derivatives; 2. halogenpyrazolanthrones themselves are not suitable for the reaction, but their acyl derivatives may be used. The acyl groups are split off partially or completely by prolonged heating, or the acylated reaction product may be saponified. In examples : 2-bromanthrapyrimidone-O-methyl ether, 2-iodo-py-C-methylanthrapyrimidine, and 2-bromanthrapyridone-O-methyl ether are heated with copper powder and naphthalene to give yellow vat dyes: 2-iodo- and 2-brom-coeramidonine give the same red-brown dye; N-acetyl-2- brompyrazolanthrone gives the N -acetyl derivative of pyrazolanthrone yellow, which may be hydrolyzed by dissolving it in sulphuric acid and pouring the solution into water. 2-Iodo and 2-brom-coeramidonine are prepared from 1-nitro-2-aminoanthraquinone, bromine or iodine being introduced by the diazo reaction, the nitro group replaced by an anilido group by treatment with aniline in pyridine, and the 2-brom- or 2-iodo-1-anilidoanthraquinone dehydrated with sulphuric acid. 2-Bromanthrapyridone is prepared by boiling 2- brom-1-acetaminoanthraquinone with potassium acetate and nitrobenzene, and gives an O-methyl ether by methylation. 2-Bromanthrapyridone is obtained from 2- brom-aminoanthraquinone with ethyl urethane- and zinc chloride, and gives an 0-methyl ether by methylation. 2-Bromopyrazolanthroneis obtained by treating diazotized 2-brom-1-aminoanthraquinone with an acid sulphite, and may be acetylated with acetic anhydride and sulphuric acid. 2-Iodo-py-C-methylanthrapyrimidine is obtained from 2-amino-py-C-methylanthrapyrimidine by the diazo reaction. The latter is prepared from u - methyl - 2(N) : 1(0)-oxazoloanthraquinone by treatment with ammonia.

Abstract: 1526667 Fluid-pressure servomotor systems STANADYNE Inc 2 May 1977 [21 May 1976] 18290/77 Heading G3P [Also in Division F1] In a fuel injection pump in which the injection timing is automatically controlled by a piston 46 subjected to engine speed dependent pressure in a chamber 50, during starting the timing is fully retarded since a servopiston 74 prevents the speed dependent pressure reaching the chamber 50 and a stop 58 resides in its rightward position shown thereby allowing full rightward retarding movement of the piston 46. The stop 58 is continuously subjected to the speed dependent pressure via passages 54, 55, 56 and a chamber 60. Thus as soon as the engine starts the stop 58 moves leftward a predetermined amount and moves the piston 46 in the advance direction. Thereafter the amount of timing advance is controlled by the servopiston 74, the latter controlling the connection of the chamber 50 to the pressure supply via passages 64, 66, 68, 70, 76, 78 and to exhaust via an axial bore therethrough and the passages 70, 76, 78. The servopiston 74 is loaded by a spring 86 the compression of which is variable by a load sensing piston 88 actuated by pressure in a chamber 89 fed by fuel downstream of a throttle valve (14, 16) in the feed line (90) to the pump working chamber.
