Title: Method and apparatus for forming a wad
Inventor: OATLEY JOHN ALBERT
IPC: D04H13/00
Filed: 1991-09-11
Granted: 2002-02-26
Abstract: A wad of particulate material is formed by entraining fibres in a stream of air that flows through an air-permeable carrier strip from top to bottom, the fibres being deposited on top of the strip. The area on the strip where the fibres are deposited is defined by an aperture in a forming screen located below, and in contact with, the strip. The air stream is a result of a suction applied below the screen. With an aperture, a uniform layer of fibre is deposited on the strip.      Instead, the screen may have a forming zone which has a region of high permeability and a region of intermediate permeability, more fibre being deposited on that area of the strip in alignment with the high permeability region than that area in alignment with the intermediate permeability region. The wad is then stabilized and bonded to the carrier and a liquid impervious backing layer is secured to the strip, sandwiching the wad therebetween. The wad or that portion of the strip and backing to which it is bonded are cut out from the rest of the strip and the backing to provide a pad.

Title: Optimum write-back strategy for directory-based cache coherence protocols
Inventor: BAYLOR SANDRA J
IPC: G06F12/08
Filed: 1992-03-12
Granted: 1998-09-22
Abstract: A directory-based protocol is provided for maintaining data coherency in a multiprocessing (MP) system having a number of  processors  with  associated  write-back  caches,  a multistage  interconnection network  (MIN)  leading to  a shared memory, and a global directory associated with the main memory to keep track of state and control information of cache lines.  Upon a request by a requesting cache for a cache line which has been exclusively modified by a source cache,  two buffers  are  situated in the global directory to collectively intercept modified data words of the modified cache line during the write-back to memory. A modified word buffer is used to capture modified words within the modified cache line.  Moreover, a line buffer stores an old cache line transferred from the memory, during the write back operation.  Finally, the line buffer and the modified word buffer, together, provide the entire modified line to a requesting cache.
Patent CA-2068804-C (CA)
Title: Electrolytic cell and process for the labeling of proteins and peptides
Inventor: SCORTICHINI CAREY L
IPC: C25B9/19
Filed: 1992-05-15
Granted: 2002-07-16
Abstract: An electrolytic cell for the labeling of proteins, peptides and other organic molecules employs a cathodic half cell and an anodic half cell, where a porous working electrode is located in one half cell and a counter electrode is located in the other of the half cell, the two half cells being divided by a separator.      A reference electrode located in the half cell containing the working electrode, and placed outside the current path between the working electrode and the counter electrode confers precise control of the working electrode potential, which allows the maximum rate of labeling to be achieved while minimizing oxidative damage to the protein, peptide or organic molecules.      Saturation of the working electrode with non-radioactive label coupled with a ratio of working electrode surface area to volume of half cell containing the working electrode between 0.001 to 10 cm-1 minimizes the problem of loss of activity of radiolabel due to adsorption on the working electrode.

Granted: 2003-09-16
Abstract: A multiple file name referencing system stores multiple file names in a file. These multiple file names include an operating system formatted file name and an application formatted file name. When an operating system formatted file name is created or renamed, the multiple file name referencing system automatically generates an application formatted file name having a potentially different format from, but preserving the extension of, the operating system formatted name. The multiple file name referencing system similarly generates an operating system formatted name upon creation or renaming of an application formatted name. A B-tree is provided which contains an operating system entry for the operating system formatted name and an application entry for the application formatted name, each entry containing the address of the same file to which both names refer. The multiple file name referencing system converts the operating system formatted file name to the application formatted file name by accessing the B-tree with reference to the operating system entry, and vice versa. As a result, either file name can be used to directly reference the file without requiring additional file name translation.

Granted: 1997-02-25
Abstract: A technique for interconnecting photonic circuits employing a fixed field of optical couplers situated between adjacent layers of photonic circuits. The coupler field facilitates the direct connection of optical fibers linked to components in one of the adjacent layers of photonic circuits with optical fibers linked to components in another adjacent layer. Each optical coupler within the field is a standard, commercially available optical fiber coupler which mates the optical fibers via a single low-loss connection. In addition, as each of these connectors allows easy connection/disconnection of optical fibers reconfiguring previous inter-layer connections is simplified. In a particular embodiment, the coupler field includes a plurality of individual couplers arranged in a regular geometric pattern upon a panel oriented at a 45° angle with respect to the circuit packs of the adjacent layers. This provides easy access to the couplers, and allows for uncomplicated indexing of each connection.
