Title: Compact multi-service ball valve
Inventor: WOZNIAK RICHARD F
IPC: F16K5/06
Filed: 1988-02-05
Granted: 1991-11-26
Abstract: COMPACT MULTI SERVICE BALL VALVE   Abstract A ball valve having a two component body with a bonnet section formed integrally with one of the body components.  A first body member defines a first flow passage and a first end of a valve chamber.  The second body member forms a second flow passage and a second end of the valve chamber.  Formed about the first flow passage is a first sleeve member which extends axially into the valve chamber. A cylindrical stem receiving chamber is also formed in the first body member and extends radially outwardly from the valve chamber to open to the exterior of the first body member through an inwardly facing shoulder.  Inner and outer radially spaced sleeves are formed integrally with the second body member and extend into the valve chamber circumferentially about the second flow passage.  The inner sleeve is aligned with the first sleeve member formed about the first flow passage on the first body member.  A valve ball is mounted in the chamber in axial alignment with the first and second flow passages.  Seat rings are positioned about the first and second sleeve members and biased into engagement with the valve ball. An operating stem is provided for rotating the ball. The operating stem is positioned axially of the stem receiving chamber and has a pair of spaced  outwardly extending integral flanges located axially inwardly of the shoulder.  Stem seal means are located between the pair of flanges and a resilient bearing ring is located between said shoulder and the outermost flange of said pair of flanges.

Abstract: LIQUID CHROMATOGRAPHY DUAL ZONE PACKING MATERIALS AND  METHOD FOR MAKING AND USING SAME                      Abstract Dual zone reverse phase packing materials for use in liquid chromatographic blood serum analysis are prepared by contacting a porous support, such as porous silica, with a fluorocarbon silane, such as a perfluorobutylsilyl compound, to form a lipophobic phase in the external zone of the porous support, and, then contacting the porous support with a lipophilic silane, such as an octadecylsilyl compound, to form a lipophilic partitioning phase in the internal zone of the porous support.  Ketal blocked diol groups, which later may be hydrolyzed to diol groups are also attached to both zones of the packing material.   The dual zone reverse phase packing materials display a reduced degree of serum protein adsorption in the external zone while drug substances are retained and separated by the lipophilic partitioning phase in the internal zone.

Title: Adaptive comb filtering system for processing video signals
Inventor: STRATTON BOYD L
IPC: H04N9/78
Filed: 1988-04-11
Granted: 1991-07-16
Abstract: Abstract The adaptive comb filtering system presented herein is used to separate the luminance and chrominance components of a composite video signal.  This video signal is comprised of a plurality of successive horizontal scan lines.  The video signal is separated into a middle (M) scan line component and vertically adjacent top (T) and bottom (B) scan line components.  These video signal components are employed to provide as a chrominance output signal either a combed chroma signal derived from the top, middle and bottom components, or an uncombed chroma signal derived from only one of the components.  The selection of the combed chroma signal or the uncombed chroma signal is determined by a transition detector which compares a vertical transition with a horizontal transition and selects one of the signals as the chrominance output signal in dependence upon the comparison.

Filed: 1989-07-13
Granted: 1995-04-25
Abstract: Certain organic polymeric materials are capable of reversibly accepting or donating electrons from a reducing entity.  The redox sites in the polymer accept electrons and, as a result, a change in the properties of the polymer occurs.  This change is useful in modifying or etching the polymeric material.  The material can be modified by incorporation of metallic seeds into the material at a controlled depth.  The seeds are incorporated by interaction of cations of the metals with the redox sites in the polymer, which cause the reduction of the cations to form the neutral metallic seeds.  Subsequent exposure of the polymeric material containing the seeds to an electroless bath causes further deposition of metal having the desirable characteristic of good adhesion to the polymeric material.  Etching of the polymeric material can be carried out as a result of an increase in solubility of the polymer in aprotic solvents when its redox sites have accepted electrons.  The increased solubility allows openings to be etched in certain areas of the polymeric material that have been reduced, leaving other areas unchanged.
