Abstract: A folding work platform apparatus is used on a support surface and includes a work platform table and at least three legs. The work platform table has a top surface and a bottom surface disposed opposite the top surface and a side wall disposed between the top and bottom surfaces to define a thickness. The work platform table might have a groove formed into the top surface that extends longitudinally along a longitudinal axis. The at least three legs movably adjoin the bottom surface of the work platform table and are movable to and between a folded state wherein the at least three legs extended from the bottom surface generally parallel with one another and an extended state wherein the at least three legs extend from the bottom surface generally angularly away from the bottom surface and from one another for supporting the work platform table on the support surface.

Abstract: An electrode sharpener has a main body that is threaded directly onto a rotary tool. The body includes a base and a housing connected to the base. The base has a threaded bore and a smaller passage centrally located above the bore through which a wheel mandrel protrudes. A shoulder is machined out of the upper end of the base. The housing, which is preferably made from round stock, is bored out such that it slips over the upper end of the base, with lower ends of the housing abutting the shoulder of the base. Fasteners are included to affix the base to the housing. An abrasive grinding wheel is mounted for rotation on the wheel mandrel and is located within the housing. An adjustment grip with knurled edges is adjustably connected to the outer surface of the housing.

Abstract: A process for producing a substantially pure organic trisulfide from mercaptan and sulfur (or high rank organopolysulfide) wherein the sulfur is reacted with mercaptan in the presence of a heterogeneous alumina-based catalyst, ammonium, alkali metal or alkaline earth metal modified silica-based catalyst, zinc-based catalyst or mixtures thereof, and recovering a product containing at least a major proportion of trisulfide.

Abstract: A process for producing a novel catalyst wherein an amorphous alumina gel is formed at least on the surface of an aluminum-containing material, the gel is heated to form crystalline .alpha.- or .beta.-alumina trihydrate and the trihydrate is sulfided, the product of said process, and the method of producing mercaptans from alcohols or ethers and hydrogen sulfide at elevated temperature in the presence of said novel catalyst, are disclosed herein.

Abstract: A process for removing sulfur from an organic sulfide containing three or more chemically bound sulfur atoms is disclosed wherein said sulfide is contacted with a defined catalyst at elevated temperature to increase the disproportionation rate and the corresponding sulfide of lower sulfur rank is continuously removed from the reaction zone.

Abstract: The process for preparing aliphatic and aromatic amines by reacting an olefin with either ammonia, a primary amine, or a secondary amine at elevated temperature in the presence of an ammonium halide catalyst, preferably a catalyst-promoter combination, is disclosed herein.

Abstract: Metallic impurities are removed from liquid organosulfonyl halides by passing the contaminated material through a bed of activated carbon, preferably activated carbon containing adsorbed water.

Abstract: Aliphatic and aromatic amines are produced by reacting an olefin with either ammonia or a primary or secondary amine in the presence of a catalytic amount of ruthenium or iron compound catalyst. The reaction is carried out in the liquid phase using an inert liquid, a product amine, or one of the reactants as a solvent. The temperatures used are 100.degree. to 250.degree. C. and the pressures are at least autogenous and up to 12,000 psig.

Abstract: A porous catalyst matrix used for the decomposition of aqueous hypochlorite solutions is disclosed along with the process for its use. The catalyst is prepared by sintering a powdered mixture of a particular metal oxide or hydroxide and a thermoplastic polyolefin or halogenated polyolefin.

Abstract: A catalyst consisting essentially of reduced cobalt which is dispersed on a high surface area support is highly efficient in the reductive amination of ethyl alcohol to ethyl amines.

Abstract: A solid catalyst composition for the vapor phase conversion of methanol and ethanol to higher linear primary alcohols (e.g., n-propanol) is made up of particles of an inert, high surface area support (e.g., gamma-aluminum oxide) impregnated with an inorganic base promoter (e.g., a basic salt of an alkali metal) and a platinum group metal (e.g., rhodium). The production of the higher linear primary alcohols is carried out by contacting a mixture of methanol, ethanol, and a carrier gas (e.g., synthesis gas) with the catalyst at a temperature of between 200.degree. and 400.degree.C. and pressure of between 1000 and 5000 p.s.i.g. at a space velocity of between 2000 and 10,000 hr.sup.-.sup.1.
