Patent ES-482963-A1 (ES)
Title: Phase lead for connecting stator coils and parallel phase rings
IPC: H02K3/22
Filed: 1979-07-30
Abstract: A dynamoelectric machine utilizing stiff, multiple component phase leads for connecting potentially misaligned stator coils and parallel phase rings. The phase leads, when attached to stator coil and phase ring coolant headers, provide electrical communication therebetween. The first and second phase lead components have a hole and cylindrical portion respectively wherein the cylindrical portion is insertable in the hole. Such phase lead hole has a longitudinal axis perpendicular to both slot elongation directions. Intimate electrical contact between the phase lead components and their connected coolant headers is insured by disposidng solder between their mateable, plane surfaces. Intimate electrical contact between the phase lead components is insured by brazing the components together at the interface between the assembled cylindrical portion and hole. Translational misalignment between the connectable phase ring and coil is accommodated in the three perpendicular directions by providing the slotted openings and permitting insertion of the cylindrical phase lead portion into the phase lead hole for selected distances. Such selective insertion is obtained by supplying extra stock to the cylindrical phase lead portion and trimming that portion to the appropriate length at assembly time.

Title: After-treatment processes and apparatus, especially for urea and ammonium nitrate plants
IPC: C02F1/00
Filed: 1980-01-31
Abstract: Disclosed are after-treatment processes and apparatus for synthesis plants, particularly urea and ammonium nitrate plants, but applicable also to various other plants in which the synthesis reaction does not go to substantial completion. In such plants product is fed to an evaporator for concentration and then to a solidification stage. The vaporous overhead stream from the evaporator contains entrained synthesis product, one or more unreacted starting materials, and solvent (usually H2O). It is condensed, and the condensate is brought into mass and heat exchange relationship with the vaporous overhead stream from the evaporator substantially without material transfer of solvent to the condensate stream. The condensate stream is thereby enriched in synthesis product, heat is added to it, and unreacted starting material is desorbed from it. The product-enriched condensate is delivered to the solidification stage for processing there. Production capacity is increased and plant effluent is decreased or eliminated.
