Abstract: Lighting apparatus for high pressure underwater use are disclosed. In one embodiment the lighting apparatus comprises a housing for withstanding ambient exterior pressure at a depth of approximately 500 feet or more, a transparent pressure bearing window positioned at a forward end of the housing, and a multilayered stack for bearing substantially all of the loading applied to the transparent pressure bearing window at a depth of approximately 500 feet or more disposed in the housing behind the transparent pressure bearing window is disclosed.

Abstract: A filler composition for use in a casting formulation, where the filler composition includes a mineral filler, hollow plastic microspheres, and a food grade and non-flammable liquid, and where when the filler composition is mixed with a casting resin an OSHA 8-hour Permissible Exposure Limit set for Particulates Not Otherwise Regulated is not exceeded.

Abstract: The invention is an eye bolt structure and method of forming including bending a straight rod to include a straight shank portion, a loop portion and a straight rod end portion, the rod end portion lying adjacent the shank portion; then placing at least one chain link around the shank and rod end portions and welding a portion of the outermost chain link to the rod end portion to maintain the loop.

Abstract: Transmission shift control apparatus includes a pin extending from a fulcrum ball to prevent rotation of an associated shift lever. Spring loads are applied to the ends of the pin to establish a neutral position for the shiftf lever in a desired shift plane. The springs are trapped in saddles, which are oriented so as to bias the ball into its seat when the spring load is applied.

Abstract: Shift control apparatus for a multiple speed, sliding gear manual transmission is characterized by the provision of a main shift rail which is rotatable for crossover selection and axially slidable for engaging the selected gear. A synchronizing clutch/brake mechanism is axially slidable in one direction for engaging a forward speed ratio and in another direction for braking and releasing the transmission countershaft. A reverse idler gear is axially slidable in said one direction for engaging a reverse speed ratio. Linkage is provided for sliding the mechanism in said one direction upon axial sliding movement of the main shift rail in a first direction, and for sliding the mechanism in said other direction and the reverse idler gear in said one direction upon axial sliding movement of the main shift rail in a second direction.

Abstract: A power transfer mechanism incorporated in a multiple path drive system comprising a source of input torque, a transfer case, and a pair of drive axles having equal axle ratios. Torque is transferred directly to the first drive axle and, when required, is transferred automatically to the second drive axle through a path including a freewheel device. Another path is provided in parallel with the freewheel device for torque transfer from the second drive axle to the first drive axle.
