Abstract: A tubular connection between an inner and an outer tubular member with the outer member having internal recesses and the inner member being mechanically forged into said recesses, the recesses and the forging being such that the outer member is not subject to a strain greater than its elastic limit and such outer member may be a relatively thin member as compared to the prior art structures. The members may be joined while in tension and the tension is preserved in the completed connection. The tool for making the connection includes a plurality of forging segments coacting with a multiple lobe cone, a pressure responsive means for creating relative movement between the forging segments and the cone and means for running the structure into a subsea casing and for supporting the other elements of the tool including the two tubular members during the forging step and being recoverable from within the forged connection.

Abstract: A small engine throttle control which includes three molded plastic parts, two mating parts forming a housing and a third part, a lever pivotally mounted in side the housing and extending to the exterior thereof with a spring detent and rack structure between the lever and the housing to retain the throttle lever in any desired set position and with an enlarged ridge maintaining the throttle lever in idle position and preventing inadvertent stopping because such detent is larger and thus requires a positive force to move the throttle lever to stop position.

Abstract: A drill bit having a roller cutter supported by ball bearings and a ball retainer retained in position both axially and rotationally within the ball loading hole by a plug which is mechanically wedged into secured and sealed position within the outer end of the ball loading hole.

Abstract: A drill bit having a body with a shaft thereon, a roller cutter, an annular thrust bearing, means for connecting said roller cutter to the thrust bearing, means for retaining said thrust bearing on the shaft, and a lubrication system containing the thrust bearing and the retaining means with the lubrication system seal positioned between the outer edge of the roller cutter and the base of the shaft.
