Patent CA-2156874-C (CA)
Inventor: PETISCE JAMES RAYMOND
IPC: G02B6/44
Filed: 1995-08-24
Granted: 2001-06-05
Abstract: In accordance with the present invention, an annular insulating core member is formed from an elastomeric material surrounding a plurality of optical fibers and maintaining the group of fibers in a predetermined configuration relative to each other. More specifically, the elastomeric material is characterized by its modulus at room temperature and its bonding to each color identified optical fiber being such as to hold together said fiber configuration while allowing interfiber movement and to facilitate the exposure of the individual optical fibers upon the application of peeling forces between the elastomeric material and an optical fiber without obfuscating the color identification of the optical fibers while providing suitable mechanical properties to maintain the integrity of the fiber configuration. Additionally, the insulating core member may be incorporated into a communication cable by enclosing the core member into a sheath system with an associated strength member. For applications with high strength demands, such as undersea environments, the cable strength members may include a central elongated filament and plural layers of stranded steel wires separated from the central filament by the annular insulating core member, in which the optical fibers are embedded. Furthermore, a metallic tubular jacket preferably surrounds the stranded steel layers to provide both a DC path for powering the optical repeaters and a hermetic moisture barrier for the fibers.

Abstract: A floor covering is disclosed which is made of rubber and has a moiré pattern.  The floor covering is made by a process including the steps of continuously feeding two or three differently coloured strips of vulcanizable, elastomeric material into a worm extruder having a perforated length to diameter ratio of 6:1 and at a working temperature of 60 to 100°C; extruding the elastomeric material through a perforated disk having 200 to 600 cylindrical bores with a diameter of 3 to 5 mm; cutting the extruded strands to particles of 1 to 2 mm length; and cooling the particles on a cooling line of 4 to 6 m length. The particles are then fed into the gap of a dual roller calender which preferably can be heated and cooled.  The compressed web exiting the calender is fed through a continuous volcanization installation and exits the latter as a finished floor covering.  The material throughput in the process is adjusted to 700 to 1300 kg/h.  The floor covering has a moiré-type pattern which, due to its oriented but not predominent pattern, can be used especially for sports facilities such as gymnasiums and without any protective coating.

IPC: G06F19/00

Granted: 1999-11-23
Abstract: The invention is a method for detecting duplicate records on a list or in a file and comprises a number of steps. The steps include entering a list, comprised of one or more records, to a data processing system; then, applying a nickname lookup table to the records to determine a common first name. Once a common name has been determined, the method matches a first record from the list with a second record from the list by comparing the fields of the first record with the fields of at least one other record; the comparison is based on a set of pre-determined criteria. The matching sequence determines a duplicate set, wherein the duplicate set is comprised of at least two records with fields that match. The method then lists matching records sequentially so that the system can create a new record by filling each empty field with a next available corresponding field from a subsequent record within the duplicate set. The newly created record is then retained on the original list; and the duplicate records are placed on a second list.  Pre-sorting of the list can occur just prior to the matching sequence as well as just prior to outputting the final list. Additionally, the system operator can be given a number of options to provide flexibility. These options can include: manually correcting a record on the duplicate records list; deleting an address record from the list of duplicates; or, outputting the record.

Title: Digital transmission framing system
Inventor: PAWLOWSKI CHRISTOPHER A
IPC: H04J3/06
Filed: 1997-10-06
Granted: 2003-12-30
Abstract: A digital transmission framing system utilizing an address array containing pointers to a framing pattern reference register.  The address array contains an entry for each set of possible framing bits.  Pointer values reference the last bit of a consecutive-bit sub-pattern of the reference register that the previously received bits in this frame bit position have matched.  As data bits are received, the associated pointer value is incremented by one to point to the next bit of the reference register, and the received data bit is compared to the newly referenced reference register bit. If the received data bit matches the newly referenced reference register bit, the associated pointer is updated with the incremented value and the corresponding frame bit position of the received data bit remains a candidate for the actual framing bit position.  This matching operation continues until only one eligible framing bit position is identified in the input data frame.  Bit 0 of the framing bit pattern in the transmission stream is then identified and a synchronization signal is generated.

Abstract: A consensus peptide of 36 amino acids has been designed which acts as an immunogen raising antibodies against the proteins of all members of the E.coli family CS4-CFA/1. While the N-terminus of members of this family of organisms shows a high degree of identity, the remainder of the sequence of the proteins shows much less homology across the strains. The region of the protein represented in the subunit encompasses known linear B- and T-cell epitopes of CFA/I. The consensus peptide has a high level of homology to strains bearing six different colonization factors. The consensus peptide is of the formula:  VEKNTTVTASVDPTIDLLQADGSALPSAVALTYSPA. An alternative peptide, identified as consensus peptide 2 is of the formula:  VEKNITVTASVDPTIDLLQADGSALPASVALTYSPA.
