The invention also provides a series of methodologies that minimize flight costs through efficient excess capacity allocation, demand modeling, forecasting and matching techniques.

Abstract: A socket for use with a rack for retaining shoes. Sockets are formed on side frame members of the shoe rack. Shoes are stored on the retaining bars fixed between opposing side frame members at the sockets. Each socket has an outer socket portion, an inner socket portion, base cavity, and a rib member extending upwardly from the base cavity. The bars are placed in the outer diameter and into alignment with the socket. Then the bars are forced into frictional engagement with the inner socket portion. The rods are supported at their ends by the upper ledge of the cavity and the rib member extending upwardly from the bottom of the cavity.

Abstract: A sports equipment rack for supporting sports equipment in an angular manner. A pair of side frame members having an elongate main body section and a plurality of support arms projecting outwardly and upwardly from each main body section. Pairs of retaining bars are positioned on said support arms and are aligned in a plane forming an acute angle with respect to vertical, to thereby support thereon sports equipment in an angular manner, with the equipment directed downwardly toward a vertical surface upon which the shoe rack is placed. The support arms, upon opposite side frames, traverse side sections of the equipment to form a barrier against lateral movement of the equipment. Additionally, each side frame member includes a unique prong for hanging the rack on an upright surface such as a door. A pair of cross bars are positioned between the opposing side members. A plurality of outwardly opening hooks are slidably attached to said pair of cross bars.

Abstract: A bowstring release with a fixed jaw and a single movable jaw is controlled by a trigger mechanism to provide enhanced accuracy. The bowstring release mechanism is adapted to rotate about its longitudinal axis to readily align the jaws with a bowstring, and the bowstring release is further attached to a wrist strap by means of a ring or attachment plate having two relatively straight sides engaged by leather tabs on the wrist strap. The straight sides and the leather tabs control and define the location of the ring thereby removing positional variances of the point of force transmission between the wrist strap and the bowstring release device and eliminate at least some variations which will affect consistent bowstring draw and release. The use of both a single fixed jaw and a movable jaw improves the accuracy and the smoothness with which the bowstring is released by stabilizing the bowstring during the initial portions of its flight after release.

Abstract: A wrist strap for an archery bowstring release has the two ends of the strap closed and attached to each other by hook and loop type fastening material. A separate web, having hooks and loops on opposite faces over a substantial porion of the web and hooks on the remainder of the surface of the web which has loops extending from the loop region to the distal end of the web, then may be wrapped around the user's wrist. The hooks on the web engage the mating loops on the outer or top surface of one of the branches of the wrist strap to insure that the first end of the wrist strap remains firmly engaged with the second end of the wrist strap.

Abstract: Chewable tablets comprising individual taste-masked coated granules comprising an analgesic and at least one water soluble medicament and methods of producing the same are described.

Abstract: A process for treating sand which includes one or more stages in which sand is mixed with a dilute aqueous solution of hydrofluoric or sulphuric acid together with zinc or sodium hydrosulphite and the resulting slurry is agitated at ambient temperature in an atmospheric oxygen-free environment.

Abstract: In an integrated process for the anodization of aluminum foil for electrolytic capacitors including the formation of a hydrous oxide layer on the foil prior to anodization and stabilization of the foil in alkaline borax baths during anodization, the foil is electrochemically anodized in an aqueous solution of boric acid and 2 to 50 ppm phosphate having a pH of 4.0 to 6.0. The anodization is interrupted for stabilization by passing the foil through a bath containing the borax solution having a pH of 8.5 to 9.5 and a temperature above 80.degree. C. and then reanodizing the foil. The process is useful in anodizing foil to a voltage of up to 760 V.

Abstract: In an integrated process for the anodization of aluminum foil for electrolytic capacitors including the formation of a hydrous oxide layer on the foil and stabilization of the foil in alkaline borax baths, the foil is electrochemically anodized in an aqueous solution of monosodium phosphate having a pH of 3.5 to 5.0 as electrolyte. The anodization is interrupted for stabilization of the foil by passing it through a bath containing a borax solution having a pH of 8.5 to 9.5 at a temperature of above 80.degree. C., and then reanodizing the foil. The process is useful in anodizing foil to a voltage of up to 550 V.

Abstract: Aluminum foil, particularly for electrolytic capacitors, is degreased and deoxidized before processing by contacting the foil with a solution containing phosphoric acid and a nonionic surfactant. An agent corrosive to aluminum may be present. Contacting time is 20 to 240 seconds, and the temperature is 45.degree. to 85.degree. C. Preferably, 1.0-7.0 M phosphoric acid is used with 2 g/l of the nonionic surfactant and 1.0-3.0 g/l of corrosive agent.

Abstract: A process is disclosed for converting hydrocarbons with a particulate catalyst containing a crystalline solid which has pore openings and maximum cage dimensions of 5.5-7.0 Angstroms; an active metal with both dehydrogenation activity and oxidation activity is disposed within the interior of crystals of the crystalline solid; the catalyst is cycled between a reactor and a regenerator, and the active metal is used for (1) selectively dehydrogenating paraffins and aromatizing aliphatics in the reaction zone while large-diameter coke-forming hydrocarbons are inhibited from contacting the metal, (2) facilitating catalyst regeneration by accelerating combustion of carbon from within the pores of the crystalline solid in the regenerator, so as to assure very low residual carbon levels within the crystalline solid in regenerated catalyst; and (3) oxidizing carbon monoxide in the regenerator to make available additional heat to compensate for endothermic conversion reactions in the cracking reactor.

Abstract: The invention pertains to rotary volumetric apparatus comprising a stationary framework and a rotary assembly mounted thereon. The rotary assembly includes a rotary shaft. The apparatus further includes a reciprocating drive engine and a driven member connected to the rotary shaft. A linkage system drivingly connects the driven member to the engine for rotation in a first direction upon reciprocating movement of the engine in a first directional mode and for rotation in a second direction opposite the first direction upon reciprocating movement of the engine in a second directional mode opposite the first mode. A clutch interconnects the driven member and the shaft and is operative upon rotation of the driven member in the first direction to cause rotation of the shaft therewith, and upon rotation of the driven member in the second direction, to permit relative rotation between the driven member and the shaft, whereby the shaft is rotated by the drive engine in temporally spaced increments.

Abstract: Coke is removed from particulate catalyst by passing coke-containing catalyst downwardly through a regenerator without backmixing, in a countercurrent flow with respect to a regeneration gas having a limited free-oxygen content, so that nitrogen oxides are reacted to form free nitrogen in a substantially oxygen-free atmosphere in an intermediate level of the regenerator, and carbon monoxide formed in the intermediate level is burned in contact with coke-free catalyst with additional oxygen introduced into an upper level of the regenerator.
