Patent CA-2319809-A1 (CA)
Inventor: GUTIERREZ ALBERTO JR
IPC: H04L12/56
Filed: 1999-02-16
Abstract: Disclosed is a new access channel protocol for use in cellular systems such as CDMA whereby the data transfer efficiency of an access message is increased by removing the requirement that a preamble frame and a message capsule frame have equal times of duration. With such removal, the BTS must inform listening MSs as to the time duration of the frames in each of the preamble and the message portions of the access channel time slot in addition to previously supplied information as to the number of frames in each portion. When unequal frame duration times are allowed, each portion of the access channel may be more nearly optimized to the actual time required to perform the functions of synchronization and message detection.

Patent CA-2325688-A1 (CA)
Inventor: LEPILLEUR CAROLE ANGELE
IPC: C08L27/06
Filed: 1999-03-18
Abstract: Blocky chlorinated polyolefins are disclosed as compatibilizers of PVC and/or CPVC resins with polyolefin elastomers. The blocky chlorinated polyolefins facilitate the dispersion of the elastomers as a dispersed phase with the proper size for impact modification of the PVC and/or CPVC. The blocky chlorinated polyolefin provides better adhesion between the elastomer and the PVC and/or CPVC providing better physical properties such as impact strength as measured by Notched Izod and variable height impact testing (VHIT) than did the randomly chlorinated polyolefins, often used as processing aids and as impact modifiers in PVC or CPVC. The differences in properties achieved with blocky chlorinated polyolefins versus randomly chlorinated polyolefins are attributed to the individual blocks of the blocky polyolefin being compatible (and/or co-crystalizable) with either the polyolefin elastomer or the PVC/CPVC  resulting in better adhesion between phases. Also disclosed is a process for making optimal blocky chlorinated polyolefins.

IPC: C03B9/36
Filed: 2000-12-12
Abstract: Apparatus for testing. sir flow through a dual-stage blowhead that includes an adapter block with a blowhead cup for releasably receiving a dual-stage blowhead. The adapter block has a first block passage for feeding test air to a first inlet of the blowhead for conducting blow air to a parison, and a second block passage for feeding test air to a second inlet of the blowhead separate from the first inlet for conducting finish cooling air. Air is directed from a common source separately to the first and second block passages, and air flow is measured in each path. When air flow through the finish cooling air path is less than a predetermined threshold, or less than a predetermined ratio with respect to the final blow air, this may indicate a need to redrill or otherwise rework the finish cooling passages in the dual-stage blowhead.

Abstract: A system and method of implementing and provisioning features and there by providing feature services in a call processing environment where features m ay be introduced, changed or removed from outside the code base. Features are introduced or "injected" into the call processing environment using a featur e registry. The feature registry is used to manage feature configuration, behavior and interactions. The code base references the feature registry to apply feature s during operation. In this manner, features can be implemented by reference without modification or rebuilding of the code base. Features. can be added, modifie d or removed without requiring a system upgrade, even while the code base is in operation. The code base uses a structured framework into which features can  be introduced by reference using the feature registry. A feature service manage r exclusively controls the feature registry and handles provisioning of features. Feature interaction potential is identified and resolved during feature provisioning. The feature service manager can be configured to enforce feature integrity a nd behaviour rules specific to the call processing product being provisioned.</ SDOAB>

IPC: B61L3/00
Filed: 1998-08-11
Abstract: A highly reliable remote emergency train braking system is disclosed. The remote emergency train braking system provides immediate initiation of train and railway brake application if a dangerous railway condition is suspected or identified. The signal can be sent directly to trains from automatic sensing devices or from Rail Traffic Control offices. If a suspect condition is identified by any detection means, an alarm is generated. The alarm signal may be transmitted over any communication system to the rail Traffic Control office and to the trains traveling toward the suspect track location. When desired, the alarm may employ wireless transmissions to stop the trains remotely. These may be catalogued as to location, time and suspected event for retrieval and analysis later.

Filed: 2001-03-29
Abstract: A method of verifying that a disc recording and reproducing apparatus normally generates or updates defect management area (DMA) information in a supplementary spare area extension mode, and a test apparatus therefore. The method includes extending the supplementary spare area of a test disc in the recording and reproducing apparatus using the test disc with test reference information and generating test information from the test disc; and comparing reference information expected from the test reference information with the test information and providing the result of verification of the test information.  Accordingly, a DMA information generation or updating function of the recording and reproducing apparatus upon the extension of the supplementary spare area can be easily verified.

Title: Ladder rack apparatus and method
Inventor: WIERSCHKE JEFFREY A
IPC: B60R9/042
Filed: 2001-04-17
Abstract: The present invention is a ladder rack providing for easier loading, unloading, and storage of a ladder. The ladder rack preferably has a pivot and a carriage mounted upon one or more arms attached to the pivot. A ladder is placed upon the carriage which can then be rotated via the pivot and arms (and preferably using a ratchet assembly) from a loading and unloading position to a stowage position separated by an obtuse angle. In some preferred vehicular applications, the unloading and loading position is beside the vehicle while the stowage position is over or above the vehicle. Also preferably, the carriage substantially overlies the ladder when in the stowage position, thereby providing for immediate and effective security against ladder theft as well as a compact ladder storage arrangement. Preferred embodiments of the present invention also employ a carriage that is slidable along the arms. This carriage has a rung grip which is separated a distance along the ladder rack from an opposed rung grip. When a ladder is mounted upon the rung grips, the grips are located adjacent respective rungs on the ladder. By sliding the carriage and ladder along the arms toward a retracted position, the distance between the rung grips shorten, thereby gripping and holding the ladder by compressing rungs of the ladder between the rung grips. One or more springs can be used to control movement of the pivot, carriage, and ladder, if desired.

Abstract: A dental fluoride rinse system comprising two different dental rinse compositions, typically maintained in separate vessels until the time that they are mixed with an appropriate solvent such as water. The first dental composition provides a non-stannous fluoride ion source and a phosphate ion source that has a pH of about 3.75 +  or - 0.75 when mixed with water. The second dry composition provides stannous fluoride and can be used by the user in combination with the initial composition so that the patient gets two different kinds of fluoride administered to the oral cavity in a short time period. In a significant advantage of the present system, the stannous fluoride can be mixed with water by the user.
