  • Patent number: 6266906
    Abstract: An extruded plastic label strip for shelf front mounting. The strip is formed of relatively rigid but flexible plastic material and has a clear front panel joined at a bottom edge to the bottom edge of a back panel structure to form a continuous, upwardly opening label pocket. An overlay panel is joined integrally with an upper edge of the front panel and extends downward over the front thereof to form a downwardly opening continuous channel for receiving thin temporary information slips to flag special items. A narrow margin of soft plastic material is co-extruded to a rearwardly facing surface of the overlay panel in a region thereof forming a gripping throat.

  • Patent number: 5339546
    Abstract: An organizing and scheduling device allows convenient organization of the multitude of notes, reminders and appointment cards which accumulate, e.g. in a home, correlating each reminder with the corresponding date on a calendar.

  • Patent number: 4243827
    Abstract: A process for the conversion of aromatic hydrocarbons, e.g., reacting an alkylating agent, preferably an olefin, with an aromatic hydrocarbon. The process uses a novel catalyst prepared by subjecting alumina to an anhydrous tetravalent titanium flouride complex of an organic compound selected from the group of organic compounds containing at least one methoxy group per molecule or organic compounds having at least one electron donor atom and double bond per molecule, and heat treating the resulting impregnated alumina in an inert atmosphere.

  • Patent number: 4243830
    Abstract: The present process is particularly adapted to those situations where a refiner lacks sufficient isobutane to completely alkylate an olefin feedstock. A field butane stream is admixed with an olefin stream, and the mixture is fractionated to provide an isobutane-olefin concentrate and a normal butane concentrate. The former is increased in pressure and reacted in contact with a hydrofluoric acid alkylation catalyst. The latter is introduced into the reaction zone wherein it is vaporized via indirect contact with the warm reaction mixture contained therein. Vaporous normal butane is recycled into the fractionation facility whereby the exothermic heat of the alkylation reaction is utilized to fractionate the first mentioned field butanes-olefin mixture. Alkylation reactions can thus be conducted at subambient temperatures resulting in improved alkylate product quality.

  • Patent number: 4237331
    Abstract: Olefins are oxidized to carbonyl compounds, for example, 2-hexene to a mixture of 2-hexanone and 3-hexanone, with a palladium/copper/boric acid catalyst and a suitable surfactant or phase transfer agent. The reaction takes place in a diluent system comprising at least two liquid phases, wherein at least one liquid phase is an aqueous phase, and in the presence of free oxygen. The catalyst system can be used to oxidize internal olefins, as well as terminal olefins, at reasonable rates. The catalyst system can also be used for the selective oxidation of linear olefins in a mixed stream containing linear and branched olefins.

  • Patent number: 4236996
    Abstract: Isomerization of xylenes in admixture with ethylbenzene by contact with a zeolite catalyst such as ZSM-5 is improved by use of zeolite which has been steamed at high temperature to reduce activity, the reaction being at a temperature above about F. At these conditions, conversion of ethylbenzene follows a different reaction path which permits high conversion of ethylbenzene to benzene without loss of xylenes of disproportionation.
