Abstract: An electrical stimulation device for applying electrical stimulus to a living body includes a pair of applicators adapted to each contact the living body. The applicators each include electrically conductive material covered by electrically insulating material whereby the electrically conductive material is separated from the living body by the electrically insulating material when the applicators contact the living body. A preferred applicator is formed of flat cable having a plurality of conductors therein that form a plurality of antennas for transmitting electrical signals to the body. A signal generator generates a series of positive electrical pulses to be applied to the living body through the applicators.

Abstract: A novel process and related apparatus for removing common contaminants from used motor oil. Propane, butane or similar solvent is mixed with the contaminated oil to form a solution. This solution is agitated and then given time to settle thus allowing gravitational separation of asphaltic pollutants. The solution is then percolated through a columned filter to remove heavy metallic contaminants and the solvent recovered by heating the solution.

Abstract: A vessel mounted for travel on a wheeled axle is adapted to feed hot liquid asphalt through a manifold to an application zone of a roof. The manifold rides on skids which fix its orientation with respect to horizontal. Special devices are mounted to follow the manifold across the application zone to first spread the liquid asphalt across the zone and to then gather and meter the spread asphalt leaving a predetermined quantity per unit area on the roof surface.

Abstract: A machine for the pouring and spreading of hot asphalt in an even and uniform manner on roof tops, the asphalt spreading machine consisting of an insulated chamber for containing hot asphalt, a piping system with port holes for regulating the flow of hot asphalt from the container on to the roof top, a pit-cock valve and valve control handle for turning on or shutting off the flow of asphalt from the container, an air vent tube to permit draining of the hot asphalt from the system when the machine is turned off, a detachable handle for pulling the machine along the roof top, and a detachable rake and spreading screens for uniformly spreading the asphalt on the roof top, with the detachable features of the machine allowing for storage of the machine in small spaces and also facilitating lifting the machine to the top of a roof.
