Abstract: An aircraft door drainage system includes a precipitation receptacle disposed longitudinally along an upper edge of an aircraft door opening. The receptacle is mounted along the upper edge of the door opening by a plurality of brackets that connect the receptacle to an inside ceiling panel of the aircraft. The receptacle protrudes outward from the upper edge of the door opening into a path followed by precipitation falling off of an outer peripheral surface of a fuselage of the aircraft from locations above, forward, and aft of the door opening into the door opening when the aircraft door is in an open position. The receptacle remains clear of the aircraft door when the aircraft door is closed into the door opening. Drain hoses are connected at first and second ends of the receptacle to direct precipitation collected in the receptacle to an outside of the aircraft.

Abstract: A critical containment room feed-through assembly with a weldment comprising a coupling member, a first gasket that is configured to seal the weldment to an interior wall or ceiling of the critical containment room, an escutcheon plate, a second gasket that is configured to seal the escutcheon plate to an exterior surface of the critical containment room directly opposed to the weldment, and a plurality of adjustable coupling devices that are configured to engage both the weldment and the escutcheon plate so as to tighten the weldment, the escutcheon plate, and both of the gaskets against the interior and exterior critical containment room surfaces.

Abstract: The apparatus of the Invention is a modular gas utility raceway for providing gas service within a clean room. The modular utility raceway has a front face and a back face coinciding with the inside and outside surfaces of the clean room walls. The utility raceway includes a vertically-oriented box-shaped beam that is open at the top to allow escape of any leaked gas above the ceiling of the clean room for the safety of clean room occupants. A support bracket supports gas pipes and connectors and extends above the top side of the clean room ceiling and discourages a user from blocking the open top of the box-shaped beam.

Abstract: A system and method for docking and using bioreactors. There is a sterile suite that is constructed and arranged to house one or more bioreactors and a human-machine interface, and a separate utility space that is not sterile, and that is constructed and arranged to house sources of electricity, liquid and gas. There is a clean-room wall separating the sterile suite from the utility space. A docking station is located in the clean-room wall, with part of it (e.g., one side) in the sterile suite and another part of it (e.g., another side) in the utility space. The docking station has electrical, liquid and gas connections that the bioreactor can connect to on the sterile suite side of the docking station, and that the sources of electricity, liquid and gas can connect to on the utility space side of the docking station.

Abstract: A multilayer, woven fabric for use in a papermaking machine includes a self-sustaining top layer including a plurality of top machine direction yarns interwoven with a plurality of top cross-machine-direction yarns and a bottom layer including a plurality of bottom pairs of machine direction yarns interwoven with a plurality of bottom cross-machine-direction yarns. Each of the bottom cross-machine-direction yarns substantially vertically underlies a respective top cross-machine-direction yarn and each of the bottom pairs of machine direction yarns substantially vertically underlies a respective top machine direction yarn, with at least one of the machine direction yarns in at least some of the bottom pairs of machine direction yarns interweaving the bottom cross-machine-direction yarns to each other and to the top cross-machine-direction yarns of the top layer.

Abstract: Multilayer woven fabrics include first and second machine direction layers, each machine direction layer including machine direction yarns extending in the machine direction of movement of the fabric through a section of a papermaking machine. One of the machine direction layers includes a plurality of pairs of contiguous machine direction yarns; each pair being spaced apart in the cross-machine-direction of the fabric from an adjacent pair and being in substantially vertically stacked alignment with a single machine direction yarn, or a pair of machine direction yarns in the other machine direction layer.

Abstract: The invention relates to the use of hydrogen ion-exchanged layered clays in organic reactions which are catalyzed by protons. Such organic reactions include the production of ethers by the reaction of an alcohol with an olefin or an olefin oxide, the production of an ether by the reaction of a primary or secondary aliphatic alcohol or an olefin oxide, the production of an alkyl aromatic compound by the reaction of an aromatic hydrocarbon with an olefin or a C.sub.2 or higher alcohol and the production of an alcohol by the hydration of an olefin.

Abstract: The invention relates to the use of metal cation-exchangeable layered clays in organic reactions which are catalysed by protons in which intercalated water is not a stoichiometric reactant. Such organic reactions include the production of esters by the reaction of an olefin or an olefin oxide with a carboxylic acid, the production of ethers by reaction of an alcohol with an olefin or an olefin oxide, the production of ethers by the reaction of a primary or secondary aliphatic alcohol or an olefin oxide, the production of bis-sec-alkyl ethers from alkenes, the production of alkyl aromatic compounds by the reaction of an aromatic hydrocarbon with an olefin or alcohol and the production of alcohols by the hydration of olefins.

Abstract: A rotary blender rotating about a horizontal axis having an elongate opening and a gate which may be hydraulically operated to open or close said opening. The blender may be loaded through the opening from the top by a hopper or front loading machine and the blended material may be discharged from the opening when the blender is stopped with the opening in an inverted position. Lifting vanes fastened to the inside of the blender in an offset V position rapidly mix particulate material as the blender is rotated.
