Title: Pvc containers for blood and blood components
Inventor: BARNES BRUCE E
IPC: C08K5/12
Filed: 1983-12-22
Granted: 1991-06-18
Abstract: Abstract A blood container for  storage of  blood  and blood components is disclosed.   The invention comprises a blood container and a multiple blood bag system which includes a donor bay and one or more satellite bags connected by flexible tubing.   The blood bag is made of polyvinyl chloride (PVC) plasticized with a blend of plasticizers comprising a plasticizer resistant to blood extraction such as a triester of trimellitic acid and a 7 - 10 carbon alcohol and a blood extract-able  plasticizer  such  as  a  dioctyl  phthalate  or dioctyl adipate and is suitable for long term storage of whole blood,  red cells and platelets.   The blood container is made of a thin material which contains a plasticizer  composition  extractable  at  much  lower levels by blood or plasma than conventional phthalate plasticized  PVC.      Blood  and  blood  components processed or stored in the blood bags will exhibit relatively   low   levels   of   contamination   by plasticizer.

Title: Method for selection of mining and drilling sites using synthesized three dimensional seismic data
Inventor: LIN JIA-WEN
IPC: G01V1/28
Filed: 1987-03-11
Granted: 1991-02-19
Abstract: Abstract A method is disclosed for converting seismic data obtained at known points to synthesized seismic traces obtainable at arbitrarily selected points.  Two dimensional seismic data are converted to dense three dimensional data with the aid of a programmed computer to permit generation of arbitrary views of a particular geo-logic structure as well as a mathematical representation of the structure.  The data is used to locate potential drilling and mining locations for drilling oil or other minerals.   In order to provide accurate interpolation from the sparse two dimensional data, both apparent and true dip characteristics are obtained for the surveyed structure, and seismic trace data for a desired point are synthesized as a function of the dip of the surveyed structure.  The dip characteristics are obtained from partial derivatives of the two dimensional data in specified coordinate directions.  A three dimensional surface corresponding to the dip characteristics is obtained by a least squares fitting technique.  The data obtained at the known points are weighted both by distance from the desired point and the semblance coefficients associated with dip for these points to synthesize the desired data.

Abstract: INVERTED BELLOWS VALVE                 Abstract of the Disclosure A bellows valve has inlet and outlet passages in fluid communication with a valve chamber on opposite sides of a valve seat.  An elongated valve stem has a first end adapted for selective sealing engagement with the valve seat, and a second end of the stem is operatively connected with an actuator assembly.  An expansible bellows has a first end secured to the valve stem and a second end sealingly connected to a closing member so that a portion of the valve stem is surrounded thereby.  The closing member engages an open end of the valve body and includes an arcuate or rounded sealing protrusion or bead adapted for mating, sealing contact with a generally planar surface on the valve body.  The sealing bead facilitates a reduction in or complete elimination of the use of lubricant between the valve body and a bonnet nut, and this, in turn, promotes clean valve operation by removing a potential contaminant.  A tapered surface on the closing member facilitates alignment with the valve body, and clearances between the closing member, valve bonnet, and bonnet nut also facilitate alignment of the assembled valve components.
