A catalyst is provided which is remarkably effective for catalyzing the oxidation of carbon monoxide to carbon dioxide at ambient conditions. This catalyst is prepared by contacting high surface area alumina with a solution of a cobalt compound (e.g., cobalt nitrate), adsorbing the cobalt compound on the alumina, removing the solvent, and thereafter heating the cobalt-treated alumina at a temperature of 400.degree.C to 1,300.degree.C in an oxygen-providing environment.

A sucrose-based syrup is increased in viscosity to provide a preferred pourability and non-absorptive characteristic on pancakes and like porous comestibles to which it is applied by a method which employs a semi-refined sugar syrup which is filtered through a diatomaceous earth media and mixed with CMC-thickened softened water operative to compensate for presence of ash and other flocculents in the semi-refined sugar syrup.

A process for manufacturing a resin which comprises reacting in the presence of a Friedel-Crafts catalyst, a Diels-Alder addition product with a benzene derivative, said Diels-Alder addition product is a compound having a formula of ##SPC1## Wherein each of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 is a hydrogen atom or methyl group, each of R.sup.6, R.sup.7, R.sup.8 and R.sup.9 is a hydrogen atom or alkyl group having one to four carbon atoms, each of X and Y is --COOH, --COOR.sup.a or --CN or X an...

A method of producing a bouyant boom made of a flexible material impermeable to water and air. An elongated sheet of the flexible material is initially disposed in an unfolded position. The sheet has first and second portions disposed adjacent the opposite edges and extending longitudinally thereof, which first and second portions are separated by an intermediate portion. Expander devices are attached to the first and intermediate portions of the sheet at spaced intervals therealong, and pieces ...

A pre-formed wax pattern of a denture, which in itself, is mass produced by a simple conventional process and a novel process of customizing said wax pattern to a finalized denture for substantially any individual patient in a fast, efficient and effective manner.

It is known to have triangular section beams with a longitudinal load-bearing member extending along each apex of the triangle and bracing members inter-connecting the longitudinal load-bearing members. Such beams have an ugly appearance, and I improve the appearance of the beam and also provide a new constructional arrangement by rolling lips on the longitudinal load-bearing members and retaining panels in these lips, the lips being arranged such that the panels can be inserted between the lips...

The production of fluted drills from tubular cylindrical blanks preferably by cold-rolling so as to press at least one spiral chip flute into the blank by means of rotating pressure rollers and thereby displacing the material of the part of the blank into which the flute is impressed so as either to increase the length of the drill over the length of the original blank or to increase the diameter of the fluted part of the drill over the original diameter of the blank the untreated end portion of...

This invention relates to an antifungal antibiotic pimaricin produced by culturing Streptomyces natalensis and the process of preparing said antibiotic.

An aquarium is provided with identical rectangular top and bottom frame members inverted one with respect to the other. Each of the frame members is made from a molded thermoplastic material. Each frame member is provided with peripheral grooves which receive upper and lower horizontal edge portions of glass panels which are positioned in end-to-end relation to form an enclosure enclosed about the lateral sides thereof. A horizontal bottom panel is supported on a projecting portion extending abo...

A method for making thermocouples and the thermocouples produced thereby including superposing an elongate conductive member and a normally solid, electrically insulative and binder material between first and second layers of thermoelectric material, heating the sandwiched assembly to at least partially liquidize or soften the insulative material and pressing the conductive member against the thermoelectric material layers, continuing the heating and pressing to join or react the conductive memb...
