Abstract: A method of preparing copper arsenate compositions having unique advantges in lower cost and higher performance for use in preparing chromated copper arsenate wood preserving formulations. These copper arsenate compositions are insoluble copper arsenate in water or as a dry reactive powder, have a mol ratio of As.sub.2 O.sub.5 to CuO of 1:4, and is readily soluble in chromic acid to form CCA wood preservatives. This copper arsenate is prepared by reacting suitable copper-bearing materials with arsenic trioxide and air or oxygen in ammoniacal solutions. Either or both of the starting raw materials, i.e., the copper and the arsenic, may be very impure, which impure materials were heretofore unsuitable for the production of copper arsenate.

Abstract: A table includes a support member having a work surface with an opening extending through the support member and the work surface. A first mechanism for mounting a router with the support member is provided. A router bit extends generally vertically through the opening and beyond the work surface. A second mechanism for mounting the router with the support member is provided so that the router bit extends generally parallel with the work surface. A mechanism for adjusting the dimension between the router bit and the work surface when the router is mounted with the second mechanism is also provided. The support member has a recess for receiving at least a portion of the router bit below the level of the work surface when the router is mounted with the second mechanism.

Abstract: The invention is a protective type mitten or glove for use as a toy with which to play with a kitten, cat, or similar sharp toothed and/or clawed animal (i.e., raccoon, ferret, etc.). The glove extends well up the forearm past the wrist, nearly to the elbow. The invention is provided with eyes and/or a nose that rattles. In addition, it has a protective material, such as heavy denim, leather, vinyl or the like, between the outer covering and the inner lining. Alternatively, if the protective inner material is sufficently protective to a hand and arm, the lining may be omitted.

Abstract: The invention produces and meters a constant supply of volatile gasoline vapors into the cylinders of an internal combustion gasoline engine. The vapors are produced by releasing them from liquid gasoline through pressure differential inside a closed vaporizer container. Vapor is transferred from the container to the fuel delivery mechanism by introducing the vapor into one or more constant vacuum inlet ports of the fuel delivery mechanism. A variable gascock valve regulates the flow of vapor. These constant vacuum inlet ports, and lines thereto, are standard components of all modern automobile engines and require no modification for installation of the invention. All gasoline burned by the engine first passes through the system's vaporizer container where a portion of the available vapor (free vapor) is released and transferred to the fuel delivery mechanism. Unvaporized liquid gasoline within the container is concurrently pumped to the fuel delivery mechanism by an auxiliary fuel pump.

Abstract: A thermally stable polyphenylene ether composition having long glass fibers of at least 4 mm length incorporated therein. A suitable high temperature binder such as polyethyloxazoline may be included in the composition, as well as a flame retardant additive or other filler.

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 hinged limb immobilizer device for setting and securely maintaining a predefined range of motion for a limb, requires no special tools for installation or adjustment. Limit stops are adjusted by simply loosening the appropriate thumbscrew, and moving the limit stop to the prescribed setting. Separate color-coded, labelled scales for flexion and extension match-up with separate color-coded thumbscrews to avoid misunderstandings. Security of adjustment is optimized by limit stops which embody both friction stop and positive stop characteristics, resulting in a unique "three-point locking" mechanism.

Abstract: Energy for melting iron oxide or wustite is supplied by pre-heated natural gas which is combusted with oxygen in gaseous form and the oxygen contained in the preheated feed materials. Such combustion produces carbon monoxide and hydrogen gas, thus the combustion products are carbonizing to molten iron. The carbon monoxide and hydrogen evolved at the surface of the molten metal is post-combusted above the bath to form a mixture of carbon monoxide, carbon dioxide, hydrogen, steam and nitrogen. The heat generated by this post-combustion is sufficient to supply the energy for all chemical reaction requirements as well as to melt the wustite charge or smelt the preheated iron oxide charge.

Abstract: A method and apparatus is disclosed for direct reduction of metal oxides, using a rotary kiln, fed with greenball pellets, the kiln having a feed-end and a discharge end. A first chamber within the kiln, and adjacent to the feed-end, is used for drying, preheating and indurating the greenball pellets. Greenball pellets are fed into the first chamber using a conventional mechanism. The feed-end is sealed to prevent egress of process gas from the kiln into the atmosphere and ingress of the atmosphere into the kiln. A first burner is used for drying, preheating and indurating the greenball pellets within the first chamber. A second chamber within the kiln, adjacent to and connected with the first chamber, having a diameter greater than the first chamber, is used for reducing the pellets, the second chamber being adjacent to the discharge end. A second burner may be used for reducing the pellets within the second chamber. Reduced pellets are discharged from the discharge end.

Abstract: The invention encompasses a pneumatic steelmaking vessle and a method for the production of steel from hot carbon-bearing metallized raw materials such as direct reduced iron. The vessle is a refractory-lined ladle, having an eccentric ladle cover with an opening on one side. Opposite the opening in the ladle cover is at least one downwardly directed oxygen lance or tuyere. The vessel is mounted on trunnions for rotation about its central axis to a generally horizontal position. The bottom of the vessel has a porous plug, and a hot metal outlet controlled by a sliding gate closure member or other convenient type closure. The vessel is used in connection with a method of steelmaking by serving as the means for transporting molten metal to melting, refining, ladle metallurgy, and teeming operations.
