Abstract: ABSTRACT           A conditioner  for  cooling  and  cleaning  hot exhaust gas containing particulates includes an enclosure partially filled with liquid and a conditioning device positioned within the enclosure.   Hot exhaust gas entering the conditioning device passes through a conditioning device liquid induction section submerged in the liquid to introduce a portion of the liquid into the hot exhaust gas to form a mixture.  The hot exhaust gas-liquid  mixture  then  flows  through  a  contact  section of  the conditioning device in which cooling of the hot exhaust gas takes place through vaporization of at least a portion of the liquid.   The cooled exhaust gas-liquid mixture is next passed through a separator section of the conditioning device in which the direction of flow of the cooled exhaust gas-liquid mixture is reversed.  Separation of the cooled exhaust gas from the liquid and particulates occurs through centrifugal action within the separator section.  The liquid and particulates removed from the cooled exhaust gas return to the pool of liquid within the enclosure, The cleaned and cooled exhaust gas is forced to strike an impingement device to remove additional liquid entrained in the cooled exhaust gas and is then passed through an outlet opening in the enclosure to atmosphere.

Title: Methods and apparatus for immunoploidy analysis
Inventor: BACUS JAMES W
IPC: G06K9/00
Filed: 1988-10-18
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus are used to measure selected features or parameters of cells by optical identification of marked cells.  Preferably, an optical enhancement factor, such as a chromogen, is bound to a specific protein in the cytoplasm of a cell in order to type a cell.  A monoclonal antibody specific to the cytoplasmic protein binds to the protein site and is magnified by an enzyme development technique.  The DNA of the cell nucleus may also be stained.  An image analysis may be made with two separate images with the stained DNA areas visible in one image and the optically enhanced cytoplasm areas visible in the second image.  These images may also be combined.  The cells are classified based on their morphological and/or optical markings.

Abstract: Title Preloaded Steering Ball Joint Assembly and Method Abstract of the Invention A preloaded steering ball joint assembly provides a system wherein relatively constant torque may be realized over the useful life of the joint.  In a preferred form, the joint assembly included a housing having a ball socket cavity, and a ball and a shaft integral with the ball.  Top and bottom bearing seats are disposed for positioning and retaining the ball within the housing.  The bottom seat includes an aperture for permitting passage of the shaft, while the top seat includes both an aperture as well as radial passageways for permitting access of lubricant into a lubricant chamber portion of the socket cavity.           A preferred method of manufacture includes insert molding an elastomer disc over the top bearing seat by a pre-measured amount of overfill, then after its formation compressing the elastomer dics by means of a second disc made of metal by peening the latter metallic disc over the elastomer disc.  The metallic disc is utilized to compress the predetermined "overfill" of elastomer, which provides a mechanism by which consistency of torque preload may be achieved in spite of tolerance variations in part dimensions.  Also, the top seat includes a barrier lip which extends circumferentially about its upper surface for preventing leakage of molten elastomer into the lubricant chamber during the insert molding process.

Title: Tri-state optical device
Inventor: LENTINE ANTHONY L
IPC: H03K19/14
Filed: 1988-11-29
Granted: 1992-04-28
Abstract: TRI-STATE OPTICAL DEVICE    Abstract A tri-state optical device 400 is disclosed having photodiodes 401 and 402 with respective quantum-wells 403 and 404 in the intrinsic regions. The photodiodes are connected in series with a bipolar switch 406 and a source of electrical potential 405 for emitting a pair of optical output beams having various combinations of power levels depending on the state of the bipolar switch and the ratio of two optical control beams incident on the photodiodes. In one state of the tri-state device with the bipolar switch in a conducting state, the two output beams have complementary high and low power levels representing, for example, high and low logic levels "1" and "0". In a second state, the power levels of the two output beams are reversed, thus exhibiting complementary and symmetric output power levels. In the third state when the bipolar switch of the tri-state device in in a nonconducting state, the output beams both exhibit a low power level, and the tri-state device is nonresponsive to the power levels of the optical control beams.

Title: Method for measuring the content of halogenated organic compounds in soil samples
Inventor: FINCH STEPHEN R
IPC: B01L3/00
Filed: 1989-03-17
Granted: 1995-01-03
Abstract: A method for measuring the halogenated organic com-pound content, e.g., polychlorinated biphenyl ("PCB") con-tent, of soil samples may effectively be carried out with an inexpensive, disposable (that is, single-use) field test kit.  The method includes contacting a weighed soil sample suspected of containing PCB or some other organohalogen con-taminant with a pre-mixture of water and an organic solvent in which water is slightly soluble.  The water extracts any inorganic halides which may be present and would adversely affect the accuracy of the test.  The organic solvent wets the moist soil sample sufficiently to extract any PCB there-in.  The resultant organic solvent phase is separated from the soil sample and aqueous phase, dried by passage through a moisture-adsorbent material to remove or at least greatly reduce its moisture content, and analyzed by means of a color-change titration to determine halide content, and thereby the PCB (or other organohalogen) content, of the soil sample.

Title: Floating dock having shock-absorbing coupling
Inventor: FRANSEN SIG T
IPC: B63B35/38
Filed: 1989-04-14
Granted: 1992-07-07
Abstract: FLOATING DOCK HAVING SHOCK-ABSORBING COUPLING  ABSTRACT A multi-element floating dock has shock-absorbing flexible tieing elements which are installed as a unit without any manual adjustment being required to create a pretension in the shock-absorbing com-ponents.  Elastomeric pads positioned in aligned cavi-ties formed in the edges of the dock sections receive the ends of the flexible tieing elements.  Stops located on the ends of the tieing elements engage the pads so that adjacent dock sections cannot be separated from one another without compressing the pads and thereby creating a compressibly yieldable restraint against the separation of the dock sections and pre-venting their being separated from one another past a predetermined limit.  An elastomeric spacer located between adjacent dock sections provides a compressibly yieldable restraint, against moving the dock sections toward one another and prevents them from coming closer to one another than a predetermined amount.  Inserts fit between the stops and the ends of the cavities to prevent adjacent dock sections from hitting one another if the spacer becomes worn or is dislodged.  A line-up sleeve located in the center of the cable is engaged by counterbores formed in the pads and by the ends of the cavities to prevent lateral and vertical movement between adjacent dock sections.
