Useful byproducts are recovered through the pyrolytic processing of biomass material such as vegetation, paper, or worn tires. The process is conducted in a sealed enclosure under vacuum or other controlled atmosphere. The biomass material is ablated and burned by crunching between counter-rotating rollers whose inner walls have been exposed to a highly heated fluid. The biomass material is preheated by injecting into the feeding duct super-heated: dry steam. A condenser within the enclosure reduces resulting vapors into oils that can be drained from the enclosure pan. Solid combustion residue is abstracted from the enclosure by an Archimedes screw.

The paintbrush-cleaning device includes a housing with an open top, a bottom drain and a central space, containing paintbrush-cleaning liquid therein. A pair of rotatable radial brushes brackets the paintbrushes in the central space and are powered by an electric motor connected to the housing. A number of spaced upwardly directed jet nozzles are disposed in the central space and direct streams of cleaning liquid under pressure upwards towards the paintbrushes. An impeller pump may be connected to a manifold in the central space, from which manifold the jet nozzles extend. Two radial brushes may be used, with the members disposed opposite each other adjacent the sides of the top opening. The radial brushes bear a bristle portion comprising cleaning bristles, which is configured in a spiral along the length of the radial wound brush. The spiral pattern and placement of the radial brushes in the central space effectively clean paintbrushes while transporting cleaning fluid upward and forward from the central space to the paintbrushes via the Archimedes screw principle. The device is simple, durable and efficient.

A modular fountain assembly for controlling the temperature and flow of viscous fluid with a melting point between ambient and approximately 150 degrees Fahrenheit is disclosed. The modular assembly for controlling the heating and flow of fluid includes an enclosed controlling base and an upper recirculation module having a detachable lower basin, one or more modular tubular sections, a small high basin on top of the highest tubular section, an Archimedes screw of a set pitch dimension to facilitate the flow of the fluid from the lower reservoir to the small high reservoir atop the tubular section or sections, and a series of circular tiers atop each tubular section. The lower basin is attached to the controlling base using mechanical or electro mechanical support structures. The controlling base provides rotational force for the Archimedes screw at variable rotational speeds to drive the fluid upward within the modular tubes as well as a heating sub module. The lower basin has an upper bowl and a lower pool of fixed set depth with an opening to permit a drive shaft attach to the Archimedes screw. The circular base controls the temperature of the fluid using a temperature probe protruding from the lower base into the lower basin. The bottom modular tube attaches to one or more vertical support structures that extends from the controlling base thru the lower reservoir. The circular tiers are held stationary between modular tube sections or between the highest tubular section and the high basin.

The helix-shaped, dog chew that has a helicoidally shaped configuration that is similar to an auger (or Archimedes' screw). The chew is fabricated from an extruded or die-cast, pliable material with the consistency of a firm rubber. The material is edible and non-harmful to animals. The helicoidally shaped configuration allows the chew to make contact with the inner and outer surfaces of the teeth to promote thorough cleaning thereof, and to also massage the gums, thereby greatly reducing the incidence of disease and bleeding.
