Abstract: 875,394. Valves. ROCKWELL MANUFACTURING CO. Sept. 8, 1958 [May 27, 1958], No. 28722/58. Class 135. A rotary ball valve 24, Fig. 1, is lubricated between the ball surface and a pair of high tensile iron seating rings 78, 80 which are mounted for limited axial and radial displacement in internal annular recesses 74, 76 in body parts 26, 28 respectively. At least the downstream seating ring engages the housing at a contact zone A, Fig. 2, and the gap X widens towards the plug bore. Each seat ring 78, 80 is located by a dowel pin 92, Fig. 1, and has spherical seating surfaces 102 and grooves which receive sealing O-rings 90. The bores of the rings 78, 80 and the ends 107 of the ball plug bore 106 may be slightly larger than the body flow passages 40, 66. The ball 24, Fig. 4, is made flat at the bottom and is of reinforced shell-like construction at the top to reduce its weight. The short lubricating grooves 128 in the ball surface, bridge long arcuate lubricating grooves 124, Figs. 1 and 2, in the seating rings 78, 80 when the valve is closed or open. Each groove 124 is supplied with lubricant via passages 134, 138 and a conducting bush 140 by either of two extrusion screw lubricators 168. A check valve 164 is located in the passage 138. To equalize the pressure round the upstream seat ring line pressure fluid is introduced into the space around the cylindrical part 108 of the ball via radial and axial passages 172, 178. The passage 172 accommodates a check valve 182 and a normally open needle valve 188 which may be closed if leakage ocours through the check valve. To ensure that the lubricant pressure is always at least equal to line pressure, one or more check valves 230 are threaded into corresponding bores 232, Fig. 2, in the rings 78, 80. A radius of the spherical seat surface through the centre of zone A passes through the centre of the lubricating groove 124 or where two such grooves are used, Fig. 12, passes midway between them. In this way maximum jacking force is obtained and there is no tendency for the lubricant to run away. Specifications 702,726, 732,886 and 847,560 are referred to.

Title: Process for the preparation of aromatic or heterocyclic dicarboxylic acids
IPC: C07D213/803
Filed: 1957-09-16
Abstract: Salts of aromatic or heterocyclic dicarboxylic acids are prepared by heating a nitrile or an amide, in which the functional group is attached directly to an aromatic ring system or a heterocyclic ring system of aromatic character, at a temperature above 250 DEG  C. in the presence of carbon dioxide in a free or combined form and an acid binding agent.  The salt may be converted into the free acid by conventional methods.  The reaction is preferably carried out at increased pressures, e.g. 5-500 atmospheres and in the presence of a heavy metal catalyst such as zinc, cadmium, mercury, iron, lead and their compounds. The preferred acid binding agents are the carbonates, bicarbonates, formates and oxalates of the alkali or alkaline earth metals and the formates and oxalates may also be used for producing the carbon dioxide for the reaction.  To prevent the reaction mixture caking the heating may be carried out in the presence of inert gases, e.g. nitrogen, methane or argon, inert liquids, e.g diphenyl or diphenyl ether, or inert solids, e.g. sand, pumice, &c.  The reaction mixture may also be kept in motion by the use of stirred vessels, screw conveyers, drag-chain conveyers and shaking or rotating autoclaves.  Mono-, di- and poly-nitriles or amides of benzene, naphthalene, anthracene, diphenyl, terphenyl diphenyl - methane, benzophenone, pyridine, pyrazine, pyrimidine, pyridazine, a  - pyran, furan, thiophene, thiazole, pyrrole, pyrazole, imidazole, quinoline, isoquinoline, indole, benztriazole and benzimidazole may be used as starting materials.  These ring systems may also carry substituents such as alkyl, halogen, carboxyl, sulphonic acid or phosphonic acid groups.  In examples, in which potassium carbonate is used as acid binding agent and cadmium fluoride is used as catalyst and where carbon dioxide is added to the reaction mixture terephthalic acid is prepared from (1), (2), (3), (7) benzonitrile, (4) benzamide, (8) o-benzodinitrile using a zinc chloride catalyst, (9) o-phthalic acid diamide, and (10) potassium phthalimide using a double salt of potassium chloride and cadmium fluoride as catalyst; naphthalene-2:6-dicarboxylic acid is prepared from (5) a - and b -naphthonitrile, (6) a mixture of a - and b -naphthonitrile in the absence of a catalyst; (11) pyridine-2:5-dicarboxylic acid is prepared from b -cyanopyridine; (12) furan-2:5-dicarboxylic acid is prepared from a -furonitrile.
