Granted: 1996-12-17
Abstract: Apparatus and method for sterilizing and encapsulating contaminated waste particularly medical implement waste (17) in which a volume of thermoplastic compound (19) having a melting point temperature-calibrated at a value which corre-sponds substantially to the temperature at which all biological contamination is rendered steril substantially on contact, and impregnating a space (12) containing contaminated waste items (17) with the liquid compound (19) and thereafter cooling the mass to its solidified phase while containing it against pro-trusion of any waste item (17). Two stage treatment of the waste is effected by utilizing a second calibrated thermoplastic (83) having a lower melting temperature in a common deformable waste container (74) with the first thermoplastic (76). The con-tainer (74) is locked in a first geometry by means of the first thermoplastic (76) so that preliminary heating liquefies the sec-ond thermoplastic (83) to at least partially encapsulate and sterilize successive charges of waste, while simultaneously creating additional space in the container (74) to receive the subsequent charges of waste. When the container (74) is heated to a final elevated temperature it is released from its initial geometry by the liquefaction of the first thermoplastic (76) to complete the final encapsulation and sterilization process.

Title: Method of making a brazeable metal pipe having tube-insertion apertures formed with guide lugs
Inventor: NOBUSUE MITSURU
IPC: F28D1/053
Filed: 1993-01-12
Granted: 2004-03-16
Abstract: A method of making a brazeable metal pipe which has elliptical tube-insertion apertures and guide lugs extending from at least one of the opposite edges defining the minor axis of each aperture, with the guide lugs extending in the direction of insertion of flat tubes. The method in an embodiment comprises the steps of: bending a part of a raw strip, which may be previously embossed to form recesses, so as to provide a bulged portion arc-shaped in cross section and connected to at least one unbulged flat portions; pressing inwardly to form inward swells; subsequently punching each inward swell to provide the tube-insertion aperture so that at least one of the opposite edges located at ends of the minor axis of said aperture remains unpunched; and finally bending the at least one unbulged portions to produce the finished pipe. Alternatively, the method may comprise the step of: punching raw apertures through the raw strip so that each aperture has protrusions; bending it to form the bulged portion; bending the protrusions to give the guide lugs; and finally bending the unbulged portions, thus any complicated die is not needed and the pipe wall is protected well from being collapsed or deformed.

Abstract: The invention is a slightly water-soluble, time release corrosion inhibitor compound for treating aluminum flake pigment. The corrosion inhibitor is the reaction product of a water-soluble metal salt including metals selected from the group consisting of yttrium and rare earth metals and an anionic metal salt including transition metal oxo-complexes and soluble salts of silicon and mixtures thereof. The corrosion inhibitor is useful for preventing hydrogen gassing of aluminum pigment particles. The compound is particularly useful for preventing gassing of bare and chromated aluminum pigment particles in aqueous compositions and in water-borne coating compositions having a basic pH. The pigment particles used in combination with the corrosion inhibitors of the present invention experience significantly less hydrogen gassing in a high pH aqueous environment and in water-borne coating compositions having high pH, than aluminum flake pigment particles and coatings without the corrosion inhibitor. The corrosion inhibitor is also effective when combined with a second corrosion inhibitor, such as a water-soluble salt of yttrium or rare earth metal in a coating composition.
