Abstract: A process for preparation of a selective hydrogenation catalyst including preparing a catalyst material containing palladium and preferably additional additive materials, prereducing the palladium material and the additional additive materials, storing the prereduced catalyst under a non-oxidizing material and distributing the prereduced catalyst in a shipping container under the non-oxidizing material to a customer for use in a selective hydrogenation reaction.

Abstract: A process for selective hydrogenation of acetylene during ethylene purification without in-situ prereduction utilizing a palladium/gold impregnated catalyst wherein the ratio of the gold to the palladium is from about 6:1 to about 50:1.

Abstract: A focusing solar heat collector comprises a light reflective corrugated base surface, a plurality of spaced apart, light-transmitting conduits positioned in the corrugations of the reflective surface so that light reflected by the reflective surface is focused on the conduits, and an organic black liquid of high boiling point circulated through the conduits to receive the focused solar light.

Abstract: A sail device for use in propelling a roller skater, ice skater or the like employs a balancing pole from which the sail material is suspended. The sail may be formed in two sections which come together near the center of the pole or may be formed in a single section with cut-outs near the center thereof to accommodate the hands of the user. The sails are generally triangular in shape, the lower corners of the sail sections, where dual sails are used, being removably attached to the shoes of the user as at the shoelaces thereof, and in the case of a single sail section, attachment being made to the user's shoe or a skateboard at or near the bottom apex portion of the triangle. In use, the user grasps the balance pole near the center thereof and suspends the sails in a desired position for propulsion by the wind.

Abstract: Light energy from the sun is directed by a solar collector device onto the end of a bundle of optical fibers. Means which may comprise a tracking system is provided to maintain the collector device directed toward the sun throughout the day so that a maximum amount of light energy is collected thereby. The optical fiber bundle is run into a building or other place where the light energy is to be utilized where the bundle may be split off to provide light in various areas through various utilization devices, such as lamps, indicator devices, signs, etc.

Abstract: A wheel having a plurality of vanes which extend centrally out to the periphery thereof, is rotatably mounted on the walls of a main compartment. A first liquid is contained within this main compartment. A second liquid having a substantially lower boiling temperature than the first is contained within a second "boiler" compartment, the second compartment being mounted in the first and at least partially submersed in the first liquid. A source of heat is applied to the first compartment to heat this compartment and the liquid contained therein to a high enough temperature so as to cause the second liquid to boil. The vapor generated by virtue of the boiling of the second liquid is conveyed to a location beneath the wheel where it is released through port means such that the vapor bubbles rise in the first liquid and in rising are caught within the vanes of the wheel, which then exerts a buoyancy force, thereby rotatably driving the wheel.

Abstract: Radioassay for vitamin B-12 using the unknown quantity of non-radioactive vitamin B-12 released from serum mixed with the radioactivity of a known quantity of radioactive vitamin B-12 tracer. A solution of intrinsic factor having a binding capacity less than the quantity of serum vitamin B-12 and radioactive vitamin B-12 is used to bind a portion of the vitamin B-12 mixture. The vitamin B-12 not bound to intrinsic factor is removed by addition of a bentonite-containing tablet. The quantity of radioactive vitamin B-12 bound to intrinsic factor is compared with standard values and the unknown serum vitamin B-12 obtained.In the steps of the procedure the acid assay medium is pre-combined with the radioactive tracer so that the radioactive vitamin B-12 tracer receives the same treatment as serum vitamin B-12. Certain of the other reagent solutions are pre-combined and the concentration of the components adjusted so that the volume used of each of these other reagent solutions is the same in different assay steps.
