Abstract: HIGH CURRENT CONTACT              ABSTRACT OF THE DISCLOSURE         A telescoping contact assembly for high current applications includes a center conductor and a coaxial con-tact sheath assembly.  The contact sheath assembly comprises a plurality of spring-loaded elongated contact fingers arranged about the inner circumference of a cylindrical housing.  Each spring is loaded so as to create a spring force directed along the length of each contact finger in an axial direction with respect to the housing.  Each contact finger is urged against a surface of the housing at a point of contact offset from the line of action of the spring force, thereby producing a radial force component creating contact pressure between each finger contact and the housing, and between each finger contact and the inserted center conductor.

Abstract: AFTER-TREATMENT PROCESSES AND APPARATUS ESPECIALLY FOR UREA AND AMMONIUM NITRATE PLANTS                            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 con-centration 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.

Means for actuating the governor before the engine reaches the set speed, means for moving the overriding means from the reference position to the other limiting positions at a very slow rate, and means for moving the overriding means toward limiting the fuel flow to a minimum when an over-running load causes the engine speed to run a predetermined amount above the set speed.  Such an engine governor combined with a load speed governor for independently governing the engine to a speed safe therefor, and to a lower speed safe for the load.
