US Patent:

47593008, Jul 26, 1988

Filed:

Oct 22, 1987

Appl. No.:

7/111430

Inventors:

Andrew H. Hansen - Van Nuys CA
William C. Walker - Buena Park CA
Richard K. Walker - Pinole CA

Assignee:

Balboa Pacific Corporation - Sante Fe Springs CA

International Classification:

F23G 512

US Classification:

110229

Abstract:

A method and apparatus for use in processing waste materials of various kinds and for reclaiming useable by-product materials from the pyrolized waste materials. The waste materials to be pyrolized are efficiently dehydrated prior to their introduction into the pyrolysis retort using microwaves generated by a large microwave generator. After the waste material is dried, initial ignition is accomplished using a very high intensity laser beam. Laser ignition is continued until sufficient methane and other volatile gases are produced for burning in a burner unit to sustain the pyrolysis reaction.

US Classification:

42218608

Abstract:

A method and apparatus for decontaminating soil which has been contaminated with hazardous hydrocarbons. The apparatus includes a blending or scrubbing unit for mixing the contaminated soil with water and a suitable surfactant to form a slurry; screening apparatus operably interconnected with the blending unit for removing from the slurry particles larger than a predetermined size to form a small particle slurry; a reactor unit operably interconnected with the screening apparatus for reacting the slurry with ozone to form an ozone enriched slurry; an ultraviolet radiation generator for irradiating the ozone enriched slurry with ultraviolet radiation; a static mixer operably interconnected with the reactor unit for mixing a floculating material with the slurry to form a floculated slurry; and a belt-forming press for receiving the floculated material from the static mixer and for forming the floculated slurry into contamination free blocks.

International Classification:

B26B 5/00
A61B 17/3213

Abstract:

A safety cutting device includes a slidable insert that moves longitudinally within a cavity of a housing. The slidable insert has a cutting blade attached and moves within the housing from a safe position in which the blade is covered to an exposed position for cutting. The safety device has a release button positioned near an anterior end of the housing. A biasing member automatically retracts the blade when the release button is activated.
