Patent YU-22492-A (YU)
Inventor: BRAISH TAMIM F
IPC: C07B61/00
Filed: 1992-03-05
Abstract: A novel process for converting trans-isomeric N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine to cis-isomeric N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine is disclosed. The process involves contacting trans-isomeric N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine, or a mixture of same with up to about an equal part by weight of the corresponding cis-isomer, with a basic equilibration agent like potassium tert.-butoxide in a reaction-inert polar organic solvent to ultimately afford a cis/trans-mixture wherein the amount of cis-amine present in said mixture achieves a constant value of about 2:1 on a weight-by-weight basis. The aforesaid resultant mixture is useful as an intermediate product that ultimately leads to pure cis-(1S) (4S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenea mine (sertraline), which is a known antidepressant agent.

Title: Device for continual casting of steel tubes with spheroidic graphite of controlled structure
Inventor: BELLOCCI RIO
IPC: C22C37/04
Filed: 1987-03-25
Abstract: The invention concerns a method and apparatus for thermally treating cast-iron pipes formed in a continuous casting die. The pipe or tube undergoes tempering by passing through a vat which is located downstream from the continuous casting die. The vat contains a continuously cooled bath of fluidized sand or the like which lowers the temperature of the tube in a uniform manner and makes it possible to obtain a very precise and homogeneous tube structure.

Abstract: An impeller with semiaxial blading and a vertical axis of rotation is rotatably arranged in a well-shaped thrust housing. The drive for the impeller is inserted into the thrust housing from above through a cover plate, and the thrust housing is closed at the bottom by a base plate which has a water inlet, arranged concentrically in the centre, for the axial flow of water against the impeller and at least one water outlet inclined at a slight angle. Arranged between the discharge end of the delivery passages of the impeller and the at least one water outlet is a baffle apparatus in which the flow energy of the water delivered by the impeller is converted to the greatest possible extent into thrust energy. The base plate (3) is structurally separate from the well-shaped thrust housing (1) and its cover plate (27), and the thrust housing is integrated in the supporting structure (42) of the ship as an integral component of it. The base plate together with the water inlet (4) integrated in it and the at least one water outlet (11) can be continuously rotated about the longitudinal axis of the thrust housing in both peripheral directions.
