Abstract: A seal assembly for a shaft and including an outer metallic band having an inner surface and an inner carbon ring having an outer surface engaged by the inner surface of the metal band. The inner surface of the outer metallic material band is caused to grip the inner carbon material ring so that relative shifting of the ring relative to the band is prevented.

Abstract: A method and apparatus are provided for forming insert molded circuits. The process includes inserting a circuit network comprised of a lace curtain with a plurality of individual circuits which are connected by interconnect members into a mold and then separating the individual circuits in the mold by cutting the interconnect members while the lace curtain is in the mold. After the interconnect members have been severed, plastic is injected into the mold thereby surrounding the individual traces. A mold for performing the process is disclosed which includes a retractable punch arrangement.

Abstract: A rivet having a cylindrical head portion, a cylindrical shoulder portion of reduced diameter and a tenon portion of further reduced diameter is projected through first and second parts which are to be fastened together. The head portion abuts one side of the first part, the shoulder portion extends a substantial distance through an opening in the first part and the tenon portion projects through and beyond a hole in the second part. An axial bore opens through the head portion and extends into the shoulder portion but stops short of the tenon portion, the bore terminating in an end wall. A first tool is projected into the bore and bears against the end wall to place substantially all of the shoulder portion in tension and to hold the rivet while a second tool engages the tenon portion to deform the latter and form an enlargement engaging the second part, the tenon portion thereby being in compression.

Abstract: A transmission selector is mounted on the floor of an automobile by elastomeric S-shaped straps which permit the selector to move back and forth in a longitudinal direction while holding the selector substantially rigid in vertical and transverse directions.

Abstract: A system of breeding, growth tanks and processing areas for commercial raising and harvesting of giant fresh water prawn, shrimp and other crustaceans including fish, the growth or rearing tanks comprising a novel arrangement of artificial reefs with special equipment provided for the culling and harvesting of the crustaceans and fish as they mature.
