Abstract: A new and improved thread rolling die, for forming a new and improved threaded fastener, comprises a plurality of first, primary thread rolling die threads, and a plurality of sets of second, auxiliary thread rolling die threads alternatively interposed between successive threads of the first, primary thread rolling die threads, so as to render the manufacturing process more cost effective by reducing the the number of revolutions, through which a blank member must be rotated in order to complete the formation of the thread leads upon the blank member, to be accordingly reduced which, in turn, permits the axial length of the thread rolling dies, and the thread rolling machines, to be reduced in size.

Abstract: Disclosed herein is a fuel metering pump for delivering fuel to rocket or jet engine having a motor driven face cam and a pair of reciprocating rolling diaphragm pump mechanisms movable through opposite suction and pump strokes. The face cam has a ramping cam surface that extends radially more than 180 degrees. This permits both pump mechanisms to be simultaneously in the pump stroke for a portion of the pump stroke so that they alternately reciprocate through the suction and pump strokes at essentially a constant velocity, thereby providing an essentially non-pulsating flow of fuel to the engine.

Abstract: A cutting tool comprised of tool hardened steel having a holder end and an opposite end. A series of axially extending slots are provided on the tool at an outer circumference of the opposite end. The slots each have a radially extending slot wall positioned so as to extend in a plane that intersects a longitudinal axis of the opposite end. Each of the slots also have a generally radially and diagonally extending slot wall confronting the radially extending slot wall associated therewith. Jig ground pins mounted in the opposite end and extended across a radially inner end of the associated slot. A series of cutter bits are mounted in the slots and bottomed on the jig ground pins positioned at the radially inner end of the associated slot. A series of cutter bits with one of the bits in each of the said slots.
