Title: The foundation brake analyzer
Inventor: HUBICK CLIFFORD B
IPC: F16D65/00
Filed: 1999-10-08
Abstract: A method and apparatus for measuring brake component wear on a s-cam foundation brake assembly without the removal of a brake drum. A foundation brake analyzer tool includes a magnet to hold the tool to the end of a plurality of s-cams. A  threaded centring pin centres the tool to the end of an s-cam and is used to secure the magnet to bottom of the first disc to form the tool base. The centring pin is the axis to which the second disc, third disc and pointer rotate on. The first disc displays, rotationally clockwise and rotationally counter clockwise degrees of rotation from 0 to 180 and is used to measure total s-cam rotation. A second disc displays brake lining dimensions and related s-cam rotation values and is mounted on top of the first disc. A pointer that is mounted on top of the third disc and is equipped with a viewing window so that total s-cam rotation values minus brake lining values equals brake drum values may be calculated and viewed. A fastener that threads to the top of the centre pin to hold the pointer, second disc and third disc to the tool base.

Abstract: A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression.

Title: Chromosome 9 and progressive rod-cone degeneration disease genetic markers and assays
Inventor: AGUIRRE GUSTAVO
IPC: C12Q1/68
Filed: 1998-06-08
Abstract: Provided are nucleic acid molecules which comprise at least a portion of a polymorphic genetic marker for determining whether a canine has a mutated progressive rod-cone degeneration disease (prcd) gene locus in one or both alleles. The genetic markers are located on canine chromosome 9 in a genomic region identified as the prcd-informative region. A method for making genetic markers representing polymorphic sequences located in the prcd-informative region of canine chromosome 9 comprises isolating a polymorphic DNA sequence in the prcd informative region, using oligonucleotides complementary with at least a portion of the sequence to amplify the sequence, and analyzing canine chromosome 9 in a prcd-informative region for the ability of the polymorphic sequence to co-segregate with the prcd gene locus by a linkage test. The presence of a mutated prcd gene locus in one or both alleles of a canine in a pedigree is detected by analyzing canine chromosome 9 in the canine for the presence of at least one polymorphic genetic marker, which co-segregates with the prcd gene locus, by a linkage analysis.

Title: Sealing arrangement for pulp dewatering arrangement
Inventor: LAMAS AXEL
IPC: D21D1/40
Filed: 2000-07-27
Abstract: Arrangement 1 for washing and dewatering a fibre pulp suspension, which arrangement comprises two hollow, circular-cylindrical screen members 2a, 2b delimited by envelope surface and end walls. The screen members rotate towards each other to form a nip 10, at least one of the said screen members 2a, 2b being arranged in a vat 6 which partially encloses the envelope of the screen member and which, in the direction of rotation of the screen member, converges towards the envelope of the screen member. The invention relates to a sealing arrangement 8 at the end wall of the screen member. By retracting the seal a distance X from the envelope surface of the screen member in a limited area .alpha. near the nip 10, the seal is relieved of the very high hydraulic and mechanical pressures which occur in the nip. Wear between the end wall of the drum and the seal at the press nip is reduced. A simple pressurized seal can thus be used with the same low pressure applied along the entire circumference.

Abstract: A mobile radio communications network includes mobile radio units, radio base stations for communicating with the mobile radio units over a radio-based channel, and a radio switching controller connected to the radio base stations for routing calls to and from various ones of the base stations. Each of the radio base stations, the radio switching controller, and/or other nodes in the mobile radio communications network includes an asynchronous transfer mode (ATM) switch connected to plural function modules. Signaling and traffic communications between the function modules are effected asynchronously to efficiently meet current service bandwidth/data rate demands using the ATM  switch and ATM switching protocol. Each function module includes a data processing circuitry that performs ATM cell buffering and other ATM control tasks in addition to other dedicated application tasks for supporting mobile radio communications. Capacity is readily increased by modularly adding function modules to vacant ports on the ATM switch without having to modify existing function modules already connected to the ATM switch. This provides considerable flexibility and scalability to adapt the radio communications networks to current needs.
