Title: Detection of chlamydia by flow-through assay
Inventor: MCLAURIN DANIEL A III
IPC: G01N33/569
Filed: 1990-11-29
Abstract: DETECTION OF CHLAMYDIA BY FLOW-THROUGH ASSAY                ABSTRACT OF THE DISCLOSURE     A  method  for  flow-through  assay  of  Chlamydia includes digesting a  sample suspected of  containing Chlamydia with Proteinase K and passing the digested sample through a microporous membrane having an anti Chlamydia  antibody  adjacent  an  absorbent  pad  which promotes  flow  through  the  membrane  by  capillary action.  Antigen bound to antibody on the membrane may be contacted with a specific anti Chlamydia monoclonal antibody conjugated to an enzyme and washed with a solution containing a chaotropic agent .  Passage of a substrate for the enzyme through the membrane causes a detectable colored spot to appear on the membrane if the sample is positive for Chlamydia.   The invention includes a reagent test kit for performing the assay.

Title: Dna probe signal amplification
Inventor: SEGEV DAVID
IPC: C12Q1/68
Filed: 1991-04-02
Abstract: The invention provides a method for amplifying a signal during the detection of target nucleic acid molecules.      A first sequence of primary oligonucleotide probe to the target nucleic acid molecules is hybridized. The primary probe has a means for binding to the bridging nucleic acid molecule, which can hybridize to a developer nucleic acid molecule. The primary probe is exposed to the bridging molecule and to a first developer molecule and a second developer molecule, under conditions where the bridging molecule binds to the primary probe and hybridizes to the first developer molecule, and the bound first developer molecule hybridizes to the second developer molecule to form a developer chain. One of the developer molecules is labelled, and the labelling can be detected in the developer chain.

Title: Multi-body mechanical system analysis apparatus and method
Inventor: CHANG YI-CHUNG
IPC: G01M99/00
Filed: 1991-05-22
Abstract: ABSTRACT OF THE DISCLOSURE          A system is disclosed which functions in two distinct yet interrelated modes.  In a modeling mode the system provides a customized multi-body model, wherein problem specific functions are created for analysis of complex real-world machines.  A preprocessor facilitates the multi-body model description and a symbolic generator then generates model specific code in FORTRAN or some other convenient computer language.  The model code is portable and self contained.  In a numerical simulation mode actual multi-body system data are combined with the model code, whereby the system is manageable by a user not necessarily familiar with the modeling techniques, but familiar with the multi-body system modeled. Simulation operations by the system produce outputs descriptive of the multi body system without redundancy, which outputs may then be utilized by the user through a post processor to compute further quantities of interest and to apply visualization to interpret results.
