Abstract: The disclosed invention is an improved TPW cell design that is designed to provide a method of removing contaminants from the TPW cell water, and improved resistance to breakage in shipping. An additional storage volume provides for transferring the liquid water from the cell body into the storage volume by inverting the cell, followed by a series of rotations. Subsequent distillation of the water into the cell body by a sub-boiling process (with vapor moving through a transfer tube and condensing in the cell body) results in removal of contaminants from the water in the cell body. The upper volume and transfer tube are configured so that transport damage is minimized by storing the liquid water in the storage volume during transport, and preventing any liquid water from moving from the storage volume into the lower cell body regardless of orientation of the cell during shipping.

Abstract: A hinged engagement and retainer device for securely holding a pair of sunglasses to a cap. The retainment device has a contoured hinged clam shell body configuration with a split resilient memory foam insert that will conform to the sunglass frame temple when closed. A fastener on the hinged body shells selectively secures the retainer device in closed position around the frame. A cap engagement pin extends from one-half of the shell body for insertion through the fabric of the cap and is held in place by a fastener slidably disposed on the engagement pin.
