Abstract: A structural honeycomb panel building system including fabrication methods and equipment provides integrated, modular structural components such as floors, walls, ceilings, trusses and roof members that can replace materials conventionally used in frame buildings. The panels are substantially impervious to moisture and other environmental hazards and may be inexpensively fabricated and assembled at the building site. The structural panels are fabricated, oriented depending upon the load bearing characteristics of each individual panel, interfitted and assembled to provide an assembly of structural panels with predetermined load bearing properties.

Abstract: A structural building panel and building system for constructing preformed or modular housing and other structures comprising a sandwich construction of an outer skin including a pair of parallel spaced opposed panels with an attached inner core comprising a third panel in combination with a plurality of fourth panels secured and arranged in spaced side by side relation transversely on either side of the third panel. A tongue like projection co-extensive with one side edge of the third panel defines a male end and a grooved section co-extensive with the opposite side edge of the third panel defines a female end. The male and female ends are adapted to interlock with respective female and male ends, which are bonded together, on adjacent like panels that are formed in a modular fashion to erect a wall, floor or roof component of the structure. Elongated channels are provided along the top and bottom portions of each individual panel to accommodate interlocking support members.

Abstract: A golf club shaft of such structure that the stiffness thereof is controlled by rotatably adjusting the shaft relative to the striking surface of the club head asociated with the shaft. The shaft is also of such structure that the torque developed on the club head upon impact with a golf ball is distributed over the entire length of the shaft, and the club head as a result thereof having a minimum tendency to rotate relative to the arcuate path through which it travels. Due to the two above-mentioned operational advantages a club embodying the shaft permits the user to impart maximum kinetic energy to the ball impacted thereby and the ball having a minimum tendency to deviate laterally in flight from an extension of the arcuate path through which the golf club head moves. The invention also includes a method of making the shaft.
