Filed: 1952-08-20
Abstract: 721,787. Revolving-cylinder pumps. GASTROW, H. Aug. 20, 1952. [Aug. 20, 1951] No. 20955/52. Class 102 (1). [Also in Group XXIX] In a revolving-cylinder pump in which the cylinder block 1 revolves on a valve pintle 12 and carries radial hollow pistons 4 actuated by an eccentric ring 5 carried by a bearing member 8 which is supported by ball or roller bearings 9 engaging slots in the member. The member 8 is adjustable on the bearings 9 and the reaction of the pistons on the ring 5 is balanced for delivery in both directions by springs 11 adjustable by bolts 12a. Wear on the bearings supporting the block 1 is taken up by using conical bearings 35 loaded by a spring 36 and thus the valve pintle is relieved of load. The partition of the valve 12 is set at an angle a to the direction of the adjustment of the block 1 thus a component of a force proportional to the delivery pressure is produced in this direction and is employed to obtain an automatic adjustment of the delivery of the pump. The bearing member 8 carries a lever 17 which can be adjusted by energizing either of solenoids 13, 14 to actuate toggles 15 to determine the direction of flow through the pump. The end of the lever 17 bears against one or other of two sets of loading springs, Each set comprises a light spring 21 and a heavier adjustable spring 23 which comes into operation after a certain lost motion and in the limit controls the pump delivery to make up losses due to leakage. A dash pot 19 permits free movement in the direction of compressing the springs but comes into operation during movement in the opposite direction. When the pump supplies. a piston 25 having unequal chambers 24, 24a on either side, the pipe leading to the smaller chamber 24a is fitted with an inlet valve submerged in the suction reservoir and the pipe leading to the larger chamber is fitted with a relief valve 31 which is opened by the pin 34 when the bearing member 8 is moved in a direction that the pump supplies chamber 24a. The pump is driven by an electric motor 3, a flywheel 2 being provided.

Title: Process for the nitration of organic compounds
IPC: C07C205/24
Filed: 1960-07-18
Abstract: Organic compounds which form solid nitration products are continuously nitrated by mixing the starting material with nitric acid, sulphuric acid and a solvent for the nitration product, pumping the resulting liquid reaction mass through a heat exchanger for effecting the reaction, withdrawing the reaction mass from the heat exchanger, withdrawing a lesser portion of said reaction mass and pumping it to a separator for separating the solution of the nitration product from the waste acid, recirculating the residual reaction mass through the heat exchanger and introducing further reaction mass into the circulating stream to maintain the volume substantially constant. The process may be effected in the apparatus of Specification 919,717.  An exemplified process nitrates 2,4-din tromethylaniline using dichloroethane as solvent to produce tetryl. Other specified starting compounds are benzene, substituted benzenes, naphthalene, substituted naphthalenes, alkyl benzenes, substituted polyalkyl benzenes, styrene, pyridine, aminopyridines, picolines, aminopicolines, quinolines, heterocyclic compounds and substituted heterocyclic compounds which form solid nitration products. Specified products are tetryl (2,4,6 - trinitrophenylmethylnitramine) pentaerythritol tetranitrate, pentaerythritol trinitrate, trinitrophenol, nitroguanidine, trinitroresorcinol and nitrated dye intermediates.
