Abstract: A method and apparatus is disclosed for very rapidly cleaning very small, colloidal particles from nuclear reactor water subjected to a high-energy waterjet cutting of metal using metal shot particles for cuffing such as garnet particles with the cutting causing fracturing of the metal shot as well as the cut metal fines into a negatively charged colloidal suspension having a large area. This colloidal suspension causes water turbidity and makes known filtration techniques impractical for rapid removal of such suspensions for recycling to the reactor.

Abstract: A lumber product for use in the cutting and assembling of lumber for the framing of a building, having a first and second end, and a face and back surface and opposite edges; and a plurality of visible marking lines stamped or imprinted on at least one surface of the lumber piece, extending generally the length of the lumber, and placed at selected intervals for framework measuring, cutting or assembly.

Abstract: A low emissivity, low shading coefficient window consisting of two panes of glass. The first pane having a low wave infrared reflecting and a visible light and shortwave infrared absorbing section of coatings on its inside surface. A second pane spaced about one half inch from the inside surface of the first pane to protect the coatings on the first pane and to insulate the coating. The infrared reflecting section consists of six layers of metals and metal oxides with the stainless steel being used for the absorption of the visible light and shortwave. The first layer consists of a metal oxide selected from the group consisting of tin oxide, zinc oxide, or a combination of zinc and tin oxide. The second layer is of silver or sterling silver. The third layer is stainless steel. The fourth layer is a barrier metal consisting of aluminum titanium, zinc, tin, nickel, chrome or its alloy. The fifth layer is selected from the same group as the first layer. The sixth layer is of titanium oxide.
