Abstract: A printing plate is made by coating a metal substrate with a polymer layer having an outer surface, coating the polymer layer with solid particles having an average particle size of less than about 30 microns, and compressing the solid particles so that most of them are below the polymer layer outer surface. The solid particles are preferably alpha-alumina particles having an average size of about 1-10 microns. The printing plate has improved wear resistance.

Abstract: A process for making an inert electrode composite wherein a metal oxide and a metal are reacted in a gaseous atmosphere at an elevated temperature of at least about 750.degree. C. The metal oxide is at least one of the nickel, iron, tin, zinc and zirconium oxides and the metal is copper, silver, a mixture of copper and silver or a copper-silver alloy. The gaseous atmosphere has an oxygen content that is controlled at about 5-3000 ppm in order to obtain a desired composition in the resulting composite.

Abstract: A method for necking an end of a metal container include effecting initial deformation, generally radially inwardly, of an axial portion to establish a necked-in generally convex transition portion and an adjacent portion disposed between the transition portion and the container end which is initially generally cylindrical. Both portions are of reduced diameter with respect to the original can body diameter. Sequentially, through the series of formation steps, the portion to be necked-in is further reduced in diameter to produce an outwardly generally convex portion disposed in underlying relationship with respect to an outwardly concave portion. A generally, radially, outwardly directed flange may be established within the end section of the necked-in portion. Apparatus to perform the foregoing forming steps consists of a plurality of die means which are subjected to relative axial movement and contact and reshape the exterior of the container portion that is to be necked-in.

Abstract: There is provided a method for making a monovalent inorganic anion-intercalated hydrotalcite-like material by first reacting a magnesium-containing powder and a transition alumina powder in a carboxylic acid-free, aqueous suspension to form a meixnerite intermediate. This intermediate is then contacted with a monovalent inorganic anion, in its acid or soluble salt form, to make a hydrotalcite-like material. The latter is then separated from the suspension. Representative materials include a bromide-, chloride-, nitrate- or vanadate-intercalated, hydrotalcite-like material.

Abstract: A method for reforming the generally cylindrical sidewalls of aluminum containers is disclosed. The method produces highly expanded and/or contoured container sidewalls which provide a distinctive appearance in comparison with cylindrical containers having straight sidewalls. Multiple expansion steps are used to expand the sidewall to a diameter substantially greater than the initial diameter of the cylindrical starting container. The sidewalls are thermally treated prior to expansion, for example, by annealing to reduce or eliminate residual stresses and work hardening. The sidewall thickness of the cylindrical starting container is preferably selected in order to maximize the total amount of sidewall expansion that can be achieved.

Abstract: A method of fabricating MMCs having high thermal conductivity coupled with coefficient of thermal expansion (CTE) values which approximates the CTE of ceramics and semi-conductor materials typically used in electronic packaging. The method comprises preparing a formed agglomeration of powder particles (preform); partially sintering the preform; placing the partially sintered preform into a forming chamber; infiltrating the preform with liquid-phase metal; and allowing the liquid-phase metal to solidify and form an MMC around and through the preform. In a preferred embodiment, the preform is constructed from silicon carbide, and the metal matrix is an aluminum-silicon alloy.

Abstract: An improved can body maker apparatus has a redraw system of reduced mass. An air actuator is incorporated into the redraw motion assembly to maintain a cam actuated arm in contact with a cam surface during the reform cycle. A improved mechanical linkage eliminates the conventional redraw carriage. The redraw sleeve is supported within a fluid bearing mounted in a stationary housing.

Abstract: A can body embossing apparatus has a first mandrel with a first tooling member adapted to receive thereon a can body and a second mandrel with a second tooling member reciprocally movable from a first position distal the first tooling member to a second position proximate the first tooling member. In the second position, the can body side wall is engaged between the first tooling member and the second tooling member. The first tooling member defines one or more recessed portions therein and the second tooling member defines one or more protuberances extending therefrom and adapted to correspond with the recessed portions. The first mandrel and second mandrel are in mechanical communication throughout the reciprocal movement of the second mandrel such that the first and second tooling members rotate continuously with respect to each other and maintain a substantially constant relative position with respect to each other.

Abstract: A method of controlling bulk absorption of atomic hydrogen and facilitating degassing of hydrogen from aluminum alloy workpieces during heat treatment in furnaces with ambient and/or moisture-laden atmospheres. The method includes exposing the surface of the workpieces to an acidified inorganic salt solution or dispersion, with the inorganic salt of the solution containing a transition metal cation and a sulfate, phosphate or nitrate anion, before being subjected to the heat treatment. The workpieces are next subjected to the heat treatment, and the acidified transition metal sulfate, phosphate or nitrate salt is used to substantially decrease the amount of atomic hydrogen entering the respective bulks of the workpiece during heat treatment and to facilitate removal of atomic and molecular hydrogen from the bulks of the workpieces.

Abstract: A method for making a synthetic mixed metal oxide or meixnerite which, when activated, has a high B.E.T. surface area, typically about 290 m.sup.2 /g or greater. The method comprises activating hydrotalcite, then cooling and hydrating such activated material with a metal salt solution in a carbon dioxide-free environment. Such hydration can produce a material that absorbs more than 100% of its weight in water. Following hydration, this material is activated a second time in a virtually carbon dioxide-free environment. Such reactivation decomposes the salt and leaves a supported metal oxide readily available to be used for catalyst reactions.

The extrusions are stretched longitudinally, bent transversely of the pulling direction, and then subjected to pressure from an incompressible fluid in a hollow interior. In a preferred embodiment, the incompressible fluid is water at a pressure sufficient to deform at least part of the extrusion outwardly of its hollow interior. The incompressible fluid reduces dimensional distortions in the shaped product.
