Abstract: A process for coating a substrate such as steel, that will hold an electrostatic charge, wherein a first coating of a thermosetting resin an amine cured opoxy resin of the family diglycidylether of bisphenol-A, is applied to the substrate electrostatically or by fluidized bed methods, a second layer of thermoplastic material is applied electrostatically to the coating of thermosetting material, the substrate is heated and the coatings are cured and bonded to the substrate and to each other at a temperature of from 355.degree. F. to 430.degree. F. for a period of about 6 to about 22 minutes, whereby the first and second coating materials become cross-linked and develop a high degree of impermeability.Coated substrates made according to the process can be used in the fabrication of items that must withstand ultraviolet or nuclear radiation plus chemical and corrosive attack including containers for toxic and hazardous materials, as well as low level radioactive materials.

Abstract: A method and apparatus for writing video information with a laser on a recording surface employing a protective foil on the writing surface through which foil the laser write beam is focussed. A stream of filtered gas is passed between the foil and the writing surface to remove any gaseous or particulate by-products of the writing process, and to protect the writing surface from room contaminance.

Abstract: A carburetor comprising a body, means to secure the body to an engine, a barrel rockably mounted in the body and means for rocking said barrel means defining a passage extending through the body and the barrel to an engine which passage can be restricted by rotation of the barrel relative to the body, the part of the passage through the body and the barrel being tapered down to the trailing edge of the barrel, the barrel having a fuel passage way defined therein extending from a tapering slot in the circumferential edge of the barrel to an opening adjacent said trailing edge of the barrel, which opening always communicates with said passage extending through said body and said barrel in all operative positions of the barrel, the tapering slot being adjacent a hole extending through the body and leading to a fuel control valve so that movement of the barrel alters the cross section of said tapering slot presented to said hole to meter the quantity of fuel to be passed through said tapering slot.
