Abstract: A system for the removal of waste from dry toilet bowls (10) and other containers adapted to have a disposable liner sheet (12) comprising an apparatus (16, 18, 20, 36) for forming elastic wads (32) from lengths of liner sheet (12) containing waste and for inserting the wads through a port (28) into a pipe (34), and an arrangement (38) for introducing air pressure into the pipe near the port to propel the wads along the pipe toward the exit (40).

Abstract: Disclosed is a mechanism for gripping and moving liner sheet (10) including a detachable cartridge having a frame (34) holding a supply of liner sheet (10) on a roll (24) for the purpose of forming a disposable liner inside a dry toilet or other adapted waste receptacle. The cartridge has spaced apart feed pads (54) with low friction faces (20) which automatically align with high friction surfaces (18) on moveable belts (12) as the frame (34) is attached to the waste receptacle. Edge portions (26) of the sheet (10) are guided between the low friction surfaces (20) and the belts (12). When the belts (16) are moved, the sheet (10) is pulled from the roll (24) and the edge portions (26) are transported around the perimeter of the waste receptacle by the belts (12) in cooperation with the low friction surfaces (20) thus causing a liner to be formed inside the waste receptacle.

Abstract: A process and apparatus to implement the process for the disposal of toilet waste in a relatively small space with low input energy. The process to include the following operations: separating the liquid portion from the solid portion of the toilet waste, disposing of the liquid portion of the waste by drainage, forming a mixture by combining the solid portion of the waste with a quantity of flammable material having structural properties that retain air passages within the mixture, storing the mixture in a chamber, and burning the mixture within the chamber.

Abstract: A dry toilet uses a substantially continuous sheet of disposable bowl lining material to convey the toilet waste out of the toilet bowl for disposal. The sheet is supplied folded on a roll and is transported by a conveyance apparatus concealed within the rim of the toilet bowl.

Abstract: Dyes which, in the presence of molecular oxygen, promote the formation of cytotoxic oxygen are used to combat internal parasites in warm blooded animals. Internal parasites having the dye incorporated therein are exposed to electromagnetic radiation to initiate one or more lethal oxidative reactions. The photosensitized parasites may be in the infective stage thereby breaking the life cycle. This reduces or prevents reinfection and the need for traditional anthelmintics.

Abstract: A board which can be conformed to a desired shape, for example, when fabricating a curved wall of a boat hull or gas tank, consists of a plurality of core strips, preferably of polyurethane foam, with mating edge surfaces of complementary shape, with webs of fibrous material, for example, glass fibre matting, interposed between the mating edge surfaces and lying flat against the outer faces of the strips. The webs are held in contact with outer faces of the core strips, for example by stitching passing through outer cover sheets, also of glass fibre material. When "wetted out" with resin the board can be conformed to a desired shape by virtue of the mating edge surfaces of the core strips. The structure forms a rigid internally reinforced structure or wall when the resin is fully cured.
