Title: Probe, kit, and method of amplification for increasing the sensitivity of nucleic acid hybridization assays
Inventor: PANDIAN SITHIAN
IPC: C12Q1/68
Filed: 1994-06-28
Abstract: The  present  invention  provides  a  method  for simplifying and significantly enhancing the sensitivity of nucleic acid hybridization assays.   A method is described whereby a single-stranded primary nucleic acid sequence that includes  a  region  of  sequences  complementary  to  a single-stranded target nucleic acid sequence is hybridized to the target molecule.  Stability of the double-stranded complex thereby formed can be enhanced by using RNA as the probe if DNA is the target or DNA as the probe if RNA is the target. The probe-target complex is subsequently immunocaptured for detection.    After  washing away  extraneous  material,  a secondary nucleic acid sequence containing many repeating sequence units is hybridized to the probe component of the immobilized probe-target complex.  Detection occurs following hybridization of many labelled nucleic acid sequence probes to each of the repeating sequence units of a nucleic acid amplification probe.   Thus, attachment of multiple labelling probes to an amplification probe that is hybridized to an immobilized probe-target complex, provides a simplified method for  amplifying  the  detection  signal  and  therefore  the sensitivity of nucleic acid hybridization assays.

Title: Computer-based method and apparatus for interactive computer-assisted negotiations
Inventor: THIESSEN ERNEST M
IPC: G06Q99/00
Filed: 1994-07-15
Abstract: A computer-based method  and  apparatus  for  interactive computer-assisted negotiations assists multiple parties involved in complex multiple issue negotiations in reaching an agreement that optimizes both the individual and overall benefit to the parties.  Each of the parties to a conflict or  dispute  to  be  negotiated  enters  their  preferences concerning each issue of the conflict into a computer system.  If desired, each party to the dispute can have a separate computer system so that each party's preference information  remains  confidential  to  that  party.    The preference  information  includes  data  on  satisfaction functions for each of the issues which defines a party's relative level of satisfaction as a function of a numerical value for the outcome of that issue.  Each party may also enter one or more proposed alternative agreements which provide the party with a specified level of satisfaction. Using standard mixed integer linear programming techniques, the  preference  information  is  employed  to  solve  an optimization problem in which an alternative agreement, known as the common base if accepted by all parties, is first generated that provides at least the same level of satisfaction  to  each  party  that  their own  proposal provides, while at the same time minimizing the maximum gain and satisfaction achieved by any party between their proposal and the generated alternative agreement.  Next, an optimal agreement to the conflict is determined,  again using linear programming techniques,  by maximizing the minimum gain  in satisfaction achieved by each of  the parties in going from the common base to the improved alternative.   This will, at the same time, maximize the overall  benefit to all  of  the parties.    For maximum security  of  all  party's  confidential  information,  a separate computer system located at a neutral site can be connected to each individual party's computer system.  In this case, alternatives are generated at the neutral site and transmitted back to each party's own computer system.

IPC: A61F13/551
Filed: 1993-12-13
Abstract: An improved fold and wrap package providing containment of a catamenial pad prior to its use and for conveniently disposing of a soiled catamenial pad. The fold and wrap package comprises a wrapper comprising a single strip of material having a flap panel, a central panel, and an end panel; and preferably a tape tab for securing the wrapper in a disposal configuration to provide convenient disposal of a soiled catamenial pad wrapped in the wrapper. The fold and wrap package is initially configured to have a pouch and a flap. The pouch is formed by folding the cad panel back upon the central panel and frangibly bonding the end panel to the central panel at the longitudinal edges so that the end panel may be easily peeled away from the central panel to provide convenient disposal of a soiled catamenial pad.     The pouch is designed so that an unused catamenial pad may be disposed within the pouch with the flap being positioned over the mouth of the pouch and frangibly bonded to the pouch to securely close the pouch prior to use. The fold and wrap package is used by peeling the tape tab from the pouch, peeling the flap away from the pouch by breaking the frangible bonds between the flap and the pouch, removing the unused catamenial pad from the pouch, peeling the end panel from the central panel to open the pouch such that the fold and wrap package is a flat wrapper (these previous two steps may also be done in reverse order), securing a soiled catamenial pad to the wrapper, disposing the wrapper and the soiled catamenial pad into a disposal configuration, and securing the wrapper and the soiled catamenial pad in its disposal configuration by securing the tape tab to another portion of the wrapper.

IPC: B01J29/06
Filed: 1994-02-15
Abstract: Oxidation catalyst compositions for treating diesel exhaust include ceria and optionally, alumina, each having a surface area of at least about 10 m2/g, and a zeolite, e.g., Beta zeolite. Optionally, platinum may be included in the catalytic material, preferably in amounts which are sufficient to promote some gas-phase oxidadon of carbon monoxide ("CO") and hydrocarbons ("HC") but which are limited to preclude excessive oxidation of SO2 to SO3. Alternatively, palladium in any desired amount may be included in the catalytic material. The zeolite is optionally doped, e.g., ion-exchanged, with one or more of hydrogen, a platinum group metal or other catalytic metals. The catalyst compositions may be used in a method to treat diesel engine exhaust by contacting the hot exhaust with the catalyst composition to promote the oxidation of gas-phase CO and HC and of the volatile organic fraction component of particulates in the exhaust.
