Abstract: The invention provides a process for preparing molybdenum and tungsten oxyhalide compounds which are useful in the deposition of molybdenum and tungsten containing films on various surfaces of microelectronic devices. In the process of the invention, a molybdenum or tungsten trioxide is heated in either a solid state medium or in a melt-phase reaction comprising a eutectic blend comprising alkaline and/or alkaline earth metal salts. The molybdenum or tungsten oxyhalides thus formed may be isolated as a vapor and crystallized to provide highly pure precursor compounds such as MoO2Cl2.

Abstract: A method and composition for cleaning and protecting vinyl, rubber and leather surfaces. The composition comprises a water-based emulsion of acrylic copolymer of RHOPLEX.RTM. HA-12, manufactured by Rohm and Haas of Philadelpha, Pa., polyethoxylated alkylphenol, and ammonium hydroxide. The ammonium hydroxide prevents coagulation that otherwise can result from freezing and thawing the composition. Application of the composition to aged and faded vinyl, rubber and leather surfaces cleans and restores the original luster and color without leaving an oily or glossy film.

Abstract: A method and apparatus are disclosed for handling a needle to reduce the likelihood of accidental pricking. The apparatus includes cylindrical sleeve for receiving a phalanx of a finger or thumb. The apparatus also includes a pair of planar magnetic surfaces supported on the cylindrical sleeve for removably holding a needle thereon. The surfaces are spaced from and flush with each other. The spacing between the planar surfaces allows the needle to be easily placed on or removed from the surfaces with the aid of a needle grasping tool. The device further includes a shield located to one side of the spaced planar magnetic surfaces to protect the wearer from accidental pricking when the needle is being placed onto, removed from, or held by the magnetic planar surfaces.

Abstract: A customized packaging arrangement, for securely containing rectanguloid articles that vary in size and aspect ratio, comprises a combination of inner and outer packages. The inner package consists of first and second rectangular paperboard sheets that are joined in superposed, transverse relation at their central portions to provide a rectangular double-walled bottom for supporting an article thereon, the two sheets extending perpendicularly therefrom to provide opposite side and end portions, which are first folded against the article sides and ends, respectively, and are then folded and joined in overlapping relation upon the article top.

Abstract: Organoclay materials formed by reacting smectite clays with a quaternary ammonium compound are improved by controlling the pH of the reaction mixture, typically to a value in the range 8 to 10, and preferably 9.0.+-.0.5, and by including in the reaction mixture a further substance, such as urea or sulphamic acid, having an unsubstituted or substituted amino or amido group.

Abstract: A cold trap system is disclosed for recovering and recycling condensable gas reactants, such as xenon difluoride. Continuous recovery and recycling is achieved through a system including a plurality of cold traps and a storage chamber having a single input/output access pipe.

Abstract: A device to weld or splice two ends of a thermoplastic yarn. The device includes means for holding the yarn adjacent a heating element. The heating element is energized and the two ends of the yarn are fused together to form a globule of molten plastic. Thereafter, the heat is terminated and the device automatically pulls the two lengths of yarn apart and holds them under tension, and at the same time, the device molds the globule into a relatively smooth mass that has a width substantially equal to the width or diameter of the yarn.
