The present invention relates to mammalian anthrax toxin receptor polypeptides and polynucleotides encoding same as well as related polypeptides and polynucleotides, vectors containing the polynucleotides and polypeptides, host cells containing related polynucleotide molecules, and cells displaying no anthrax toxin receptor on an exterior surface of the cells-minus cell lines and animals. The present invention also relates to methods for identifying molecules that bind the anthrax toxin receptor and molecules that reduce the toxicity of anthrax toxin. Finally, the present invention provides methods for treating human and non-human animals suffering from anthrax.

摘要:
A group of several identical interconnected but separable key ring support members arranged as a composite structure. Each of the support members has a respective attached key ring. Each support member has two separate attachment parts at different locations on said member for directly connecting it to one or more members of said group by manually pressing the several members together. Manually releasable interlocking attachment parts enable one or more of the key ring support members to be selectively separated from the composite structure.

A forced air circulation system for an enclosed room with a floor, room walls, and a ceiling. The system includes at least one distributor unit positioned adjacent the base of at least one of the room walls. The distributor unit has an elongated center section, an inlet opening for receiving forced circulation air, and an elongated outlet passage of smaller cross-sectional area than that of the inlet opening. The system also provides a deflector unit positioned on the room wall substantially upwardly of the distributor outlet passage. The deflector unit has surface portions approximately parallel and perpendicular to the wall surface as well as a transition portion connecting these surfaces. Supply and return conduits are provided for directing forced air to the distributor unit inlet and withdrawing the circulated air from the room.
摘要:
Rayon/nylon and other sheath/core composite fibers or other materials, with good adhesion between sheath and core resulting from an adhesion promoter. The adhesion promoter is difunctional and sterically hindered. Fumaric acid and terephthalic acid are preferred adhesion promoters for the composite fibers or other materials, because each compound has both difunctionality and steric hinderance, allowing either to form covalent bonds to both the sheath and the core. Fibers produced in accordance with this invention may be used to produce fabrics which have the strength and wrinkle resistance shown by a number of synthetic fibers, but with the water absorption characteristics of natural fibers such as cotton.

A key holder comprising two identically shaped parts each having a retainer for a plurality of apertured keys, the holder having at least one pair of mating latching structures holding the parts together when engaged and permitting the parts to be separated by only manually pulling the parts apart. Each latching structure includes a combination of a protuberance on one part and a cooperating protuberance-retaining recess on the other part. Each part has at least three distinct layers with first and second of the layers being thin flat and parallel and defining a space therebetween and a third layer offset with respect to the first and second layers. The third layer of each part lies parallel to and between the first and second layers of the other part with each third layer having a protuberance on one or both of its opposite faces, which protuberances are received in and retained by respective recesses in opposing faces of the first and second layers of the other part.
摘要:
A sheath core fiber having an inner continuous core made from an oriented thermoplastic material, such as polyester, nylon, acrylic, and olefin, and a sheath made of a nonthermoplastic material, such as regenerated cellulose and protein. The fiber maintains the crease and tear resistance of the core material, yet has the water sorptivity and dyeability of the sheath material.A method of manufacturing such a fiber is also disclosed.

A multi-level access flooring system having a work area floor and at least one intermediate floor, defining at least one isolated wireway between the intermediate floor and the work area floor, and at least one relatively unobstructed plenum, between the intermediate floor and the building floor, together with at least one HVAC inlet to such plenum and a plurality of individual outlets, with each outlet having its own flow control damper, together with a suitable control system for positioning the individual dampers and regulating the heating/cooling load of the HVAC unit to achieve localized as well as generalized control of climate within a building room.
摘要:
A composite extrusion, such as a fiber, film or ribbon, having an inner core and an outer sheath, wherein the inner core is made of a molecularly oriented polymer capable of being rigidified by imposition of a temperature gradient and the sheath is made of a polymer wherein its molecules are generally not oriented. A method of making such a composite extrusion utilizing melt transformation coextrusion wherein the inner core-forming material is caused to assume a molecular orientation coaxial to the longitudinal axis of said core while in a molten state and then forced through a reducing die while being subjected to a temperature gradient while surrounded by the liquid sheath-forming material such that crystallization in at least the outer skin of said core occurs within the die but the sheath-forming material does not crystallize until the extrudate exits the die.
