Abstract: For OTEC (Ocean Thermal Energy Conversion), rather than transferring large quantities of surface heat from near the ocean surface used to vaporize a working fluid to drive a heat engine (turbine) and generator to the deep ocean to provide a heat sink, this invention provides a method of using small masses of low-boiling-point fluids to absorb heat in a heat pipe near the ocean surface using the latent heat of evaporation and returning the heat of condensation of the vapor in a condensed working fluid pumped back to the ocean surface in a counter-current heat pipe system. The counter-current flow minimizes the amount of heat that is absorbed from the surface to vaporize the working fluid as well as the mount of heat dumped into the deep ocean.

Abstract: A cut alignment device for a rotary saw having a motor which spins a cutting unit which includes a rotary shaft driven by the motor, a circular blade having a central aperture through which the shaft fits, and a blade mounting device for holding the blade on the shaft, the cut alignment device including: a battery power source carried by the cutting unit; and a beam light source, operatively connected to this power source, and carried by the cutting unit; wherein the light source projects a light beam from the cutting unit directed along the cutting edge of the blade to assist the operator in cutting accurately.

Abstract: A method for the disposal of nuclear and toxic waste materials comprising the placing of waste materials into waste repositories radiating from an access tunnel constructed into a subtending tectonic plate adjacent or as near as possible a subduction zone. The waste materials descend within the tectonic plate into the mantle of the earth.

Abstract: A quick coupler for front end loader implements having a male master pivotally connected by pins to the upper and lower extendable arms of a front end loader and a female coupler attached to any of a variety of buckets, plows, scoops, forks, or other implements. The female member consists of a pair of upper hooks and lower protruding eyes engageable by the male member having a pair of upper bridge pins and lower, channeled slots. Upper engagement is made between bridge pins and hooks and lower engagement by insertion of the protruding eyes into the slotted channels. Coupling is secured or released by extension or retraction of hydraulically or manually actuated pins through the slotted holes and protruding eyes.
