Based on scientific discoveries at Kano Laboratories, Kroil creeps into millionth inch spaces, dissolves rust and lubricates to loosen frozen metal parts. Kroil’s unique molecular structure creates an affinity to metal assuring swift penetration.

Roof Hugger and McElroy Metal experts will collaborate at the International Roofing Expo to present "Retrofit with Metal Systems" on Feb. 6 and 8 at the Las Vegas Convention Center.

A layered compound-metal particle composite 3 is obtained by the addition, to an organically modified layered compound 1 formed by the intercalation of organic ions between layers of a layered compound, of both an aqueous colloidal metal solution 2 in which metal particles are dispersed as a metal colloid in water, and a nonaqueous solvent which is a poor solvent for the metal colloid and has an excellent ability to swell the organically modified layered compound 1.

A method for producing a metal part, the part including, in particular, a first set of elements having a small thickness, and a second set of elements having a large thickness, the method including: forming a peripheral portion of the elements of the second set of elements by selectively melting a powder by scanning the surface of the powder layer with a laser beam or with an electron beam; using the peripheral portion of the elements of the second set of elements as a mould by carrying out an operation of filling an inner area defined by the peripheral portion with liquid metal; cooling the metal part to solidify the inner area defined by the peripheral portion and filled with metal.

A foundry mixture for making molds used for molding cast metal parts includes foundry sand, a non-aqueous binder, and a cleaning agent that includes calcium oxide. Residual foundry mixture remaining on the cast part after removal from the mold is removed by electrolytic cleaning of the cast part.
