摘要： A gas-liquid mixing system employs an impeller/draft tube assembly submerged in liquid. Hollow eductor tubes affixed to the impeller drive shaft are used to flow gas from an overhead gas space to the liquid in the vicinity of the assembly. The positioning and size of the eductor tubes are such as to maximize the desired gas-liquid mixing and reaction rate.

摘要： This invention relates in general to the formation of multiaxially (e.g., biaxially) oriented films from high molecular weight lyotropic or thermotropic polymers (homopolymers, copolymers, and the like), wherein due to the processing conditions employed, the films have a controlled molecular orientation. The films of the present invention are preferably prepared from rod-like extended-chain, aromatic- heterocyclic polymers. These polymers generally fall into two classes; first, those that are modified in solution form, i.e., lyotropic liquid crystalline polymers; and second, those that are modSTATEMENT OF GOVERNMENT INTERESTFunding for the present invention was obtained from the Government of the United States by virtue of Contract Nos. F33615-83-C-5120 and N00164-87-C-0050, from the Departments of the Air Force and the Navy, respectively. Thus, the Government of the United States has certain rights in and to the invention claimed herein.

摘要： The present invention relates to a method and apparatus for the generation of essentially spherical frozen droplets of a liquid biological or organic-comprising composition. The liquid composition if fed under positive pressure through a nozzle in a manner which provides a continuous stream of the liquid composition exiting the nozzle; the continuous stream travels through a gas or vapor for a distance sufficient to cause the continuous stream to break apart, forming droplets ranging in size from about 0.6 mm to about 5 mm; the liquid composition droplets are then contacted with a cryogenic liquid capable of freezing the droplets into a solid phase; the frozen droplets are concentrated into a portion of the contacting cryogenic liquid from which they are subsequently separated.

摘要： A prosthesis for an inadequate or diseased heart valve, the prosthesis being formed of a porous fabric comprising multifilament synthetic yarns supported on a plural-lobed frame. The frame has generally parallel legs each comprising a pair of rod portions. The fabric is inserted between the rod portions of the legs to form flexible leaflets. Each leaflet consists essentially of a textile of filaments having a substantial number of open interstitial spaces in the range of 20 to 40 microns evenly distributed throughout the fabric. The resulting composite structures are free of thrombogenic complications.
