Abstract: A resonant optical cavity having a laser medium therein is positioned within a specific environment, such as a process and/or harsh environment, and a sensing region, also within the resonant optical cavity, receives light whereby particles at the sensing region affect, as by scattering, light at the sensing region.  The affected light is optically collected within the specific environment and optically coupled to a processor outside the specific environment where an output is provided that is indicative of particles detected at the sensing region, including small particles having a size at least as small as about 0.05 to 10 microns.  With a solid state laser medium utilized within the resonant optical cavity, the solid state laser medium is pumped by an actuator, such as a semiconductor diode laser, providing a light output that is optically coupled to the solid state laser medium.  Optical coupling includes fiber optics and lenses for focusing light into and out of the fiber optics, as well as a notch filter through which scattered light is coupled to the processor, and, with the specific environment contained within a housing, an optical feedthrough is utilized to couple light through the housing.

Abstract: In an angularly adjustable, releasably lockable ball joint, the ball has a surface covered with regular polygonal patterns of spaced-apart engaging surfaces, such as protuberances engaged in position on the surface of the ball or spherical members disposed on the surface of the ball and free to move about the ball surface. Theengaging surfaces define concavities therebetween. An actuator tip is provided to penetrate at least one concavity and simultaneously contact all of the engaging surfaces of the pattern to lock the ball -actuator together, thereby fixing the orientation of shanks attached to the ball and actuator. A mechanism for driving the actuator is also taught which comprises a housing and an overcentre assembly of two interlocking parts which are driven between the overcentre and collapsed position by use of aunattached sled which moves axially within the housing and is driven by a pair of buttons extending from the housing. A terminal device locking mechanism is taught for releasable locking a terminal device to a prosthetic limb. The locking device includes a biased retaining means which allows passage of a stem of the terminal device into the bore of a prosthetic limb but which engages the stem once it has been fully inserted. The stem is released from the bore by driving the biasing means out of engagement with the stem.

IPC: G01N21/55
Filed: 1997-06-12
Abstract: In a near infrared absorbance measurement  instrument,  an attenuated internal reflectance probe comprises a quartz rod having an inexpensive low purity central core surrounded by two high purity quartz layers.  Narrow band infrared light is transmitted axially through the outer layer to cause the light to undergo total internal reflection from the inner and outer surfaces of the outer layer.  A near infrared light detector measures the light transmitted through the  outer  layer  to  obtain  a measurement  of  the absorbance of the fluid in contact with the outer surface of the outer layer without any interference from suspended particles or bubbles in the fluid being measured.

Title: Method and apparatus for a physical storage architecture for a shared file environment
Inventor: WLASCHIN SCOTT
IPC: G06F17/30
Filed: 1996-02-01
Abstract: A distributed storage system provides a method and apparatus for storing, retrieving, and sharing data items across multiple physical storage devices that may not always be connected with one another. The distributed storage system of the present invention comprises one or more "partitions" on distinct storage devices, with each partition comprising a group of associated data files. Partitions can be of various types. Journal partitions may be written to by a user and contain the user's updates to shared files. In the preferred embodiment, journal partitions reside on a storage device associated with a client computer in a client-server architecture. Other types of partitions, library and archive partitions, may reside on storage devices associated with a server computer in a client-server architecture. The files on the journal partitions of the various clients may, at various times, be merged into a file resident within the library partition. If two more clients attempt to update or alter data related to the same file, the system resolves the conflict between the clients to determine which updates, if any, should be stored in the library partition. The merge operation may occur at various time intervals or be event driven. The archive partition stores files from the library partition.

Filed: 1998-01-27
Abstract: An improved method is provided for the thermo-chemical dewaxing a large dimension line or conduit using a Nitrogen Generation System/Emulsion. The method involves introducing an emulsion into the conduit to be dewaxed. The emulsion comprises an internal aqueous phase and an external organic phase. The aqueous phase comprises an oxidizing nitrogen salt, a reducing nitrogen salt and water. The organic phase comprises a non-polar organic liquid, such as kerosene, and a delayed action activator for inducing the reaction of said oxidizing nitrogen salt and said reducing nitrogen salt. The improvement comprises a delayed action activator which may be a copolyanhydride such as poly(adipic-co- sebacic)anhydride solubilized in a polar organic solvent such as chloroform. The solubilized delayed action activator is easily and accurately pumped into the conduit to be dewaxed. The emulsion is maintained in the conduit until the delayed action activator induces the reaction of the nitrogen salts to generate nitrogen and heat, thereby fluidizing wax in the conduit.
