Title: Method and apparatus for making pile assemblies and products therefrom
Inventor: EDWARDS MARK STEPHEN
IPC: A46B3/06
Filed: 2002-10-24
Abstract: An apparatus or method for forming a pile assembly (100) without the use of additional materials as an adhesive or preformed core, and the products/articles made therefrom. The method and apparatus uses the beam or base member of the elongated pile sub-assemblies (e.g. tuftstrings or rooted tuftstrings) to form a continuous tubular core. This method and/or apparatus can be used to form articles such as brush rollers, interior panels for various modes of transportation, or a flooring article. The melt flow of the beam adjacent to one another along a mandrel surface (104) form a continuous base material. In the case of a roller brush this base material forms a core from which the pile for roller brushes radially extend. Making a roller brus h or other article in this manner eliminates the cores adhesives and fabric support material normally required for the pile yarn. Also a mandrel can be used to form a variety of geometric shapes for the cores of the present invention.

Title: Filtering face mask that uses an exhalation valve that has a multilayered flexible flap
Inventor: MARTIN PHILIP G
IPC: A62B23/02
Filed: 2002-10-03
Abstract: A filtering face mask that includes a mask body and an exhalation valve. The mask body is adapted to fit at least over the nose and mouth of a wearer to create an interior gas space when worn, and the exhalation valve is in fluid communication with the interior gas space. The exhalation valve comprises a valve seat that has a seal surface and an orifice through which an exhale fl ow stream may pass to leave the interior gas space. A flexible flap (22) is mounted to the valve seat such that the flap makes contact with the seal surface when the valve is in its closed position and such that the flap can flex away from the seal surface during an exhalation to allow exhaled air to pass through the orifice to ultimately enter an exterior gas space. The flexible flap has at least first (44) and second (46) juxtaposed layers wher e at least one of the layers is stiffer or has a different elastic modulus tha n the other layer.

Inventor: PACKARD BEVERLY S
IPC: C12Q1/37
Filed: 2003-01-29
Abstract: This invention provides a non-radioactive assay to monitor and quantify the target-cell killing activities mediated by cytotoxic T lymphocytes (CTLs). This assay is predicated on the discovery that apoptosis pathway activation and, in particular, caspase activity, provides a measure of cytotoxic effect or cell activity. In one embodiment, measurement of CTL-induced caspase activation in target cells is achieved through detection of the specific cleavage of fluorogenic caspase substrates. This assay reliably detects antigen-specific CTL killing of target cells, and provides a more sensitive, more informative and safer alternative to the standard 51Cr-release assay mo st often used to quantify CTL responses. The assay can be used to study CTL- mediated killing of primary host target cells of different cell lineages, an d enables the study of antigen-specific cellular immune responses in real time at the single-cell level. As such, the assay can provide a valuable tool for studies of infectious disease pathogenesis and development of new vaccines a nd immunotherapies.

Filed: 1999-04-14
Abstract: A diagnostic platform includes a processor, storage media and user interfaces, including a display screen, the processor being coupled to engine analyzer hardware and adapted to be coupled to a scanner for downloading data from vehicle on-board computers. The system stores libraries of information regarding vehicle identifications, drivability symptoms exhibited by vehicles, vehicle system and component tests and service codes which can be registered by the vehicle on-board computer. System software permits the user to input an identification of the vehicle under test and, in one mode of operation, displays a library of faults, such as symptoms or service codes, from which the user can select those exhibited by the vehicle, whereupon the system selects from the test library those tests pertinent to diagnosis of the causes of the selected faults and displays them in a hierarchically ranked order based on likelihood of successful diagnosis of the faults. The user can then select and initiate any displayed test. In other modes, the system initially displays one of the libraries of system or component tests, from which the user selects those deemed appropriate, whereupon the system highlights icons which can be selected for initiating pertinent test procedures. Selected test procedures may include links to the engine analyzer or scanner hardware or other appropriate test modules.
