Patent CA-2066558-A1 (CA)
Inventor: BOLLIGER BRIAN D
IPC: H04L7/00
Filed: 1992-04-21
Abstract: A wireless-access communications system, such as a CDMA cellular radio-telephonesystem (FIG. 2), comprises a packet-switched communications network (202, 207, 201) that interconnects cells (base stations; 202) with each other and with the public telephone network (100). Traffic of individual calls is packetized, and packet-bearing frames (300 in FIG. 7) of a plurality of calls are then statistically multiplexed and frame-relayed through the network to yield the high capacity, efficiency, and speed of traffic transport and handoff required for a CDMA cellular system. At each call processing unit (264 in FIG. 5), individual calls are handled by individual service circuits (602 & 612) which perform speech-processing functions such as coding and decoding, tone insertion, and echo cancellation, and packet-to-circuit-switched-PCM traffic conversion. Processors (602) adapt call processing unit timing to compensate for asynchrony between cells and call processing units and variations in call path transmission delays. Cell-to-cell communications, fixed call path addressing, and packetized control message transfers ensure that the same service circuit handles a call through even multiple soft handoffs (FIGS. 27 - 29) and efficiently communicates simultaneously with all cells involved in the handoff without involvement of system control entities and negative effect on system call-handling capacity. Both coded (packet-switched) and uncoded (circuit-switched) radio-telephone traffic are accommodated side-by-side. Wherever possible, existing and proven technology and component units are used to achieve low cost and high reliability.

Title: Optimum design of two-dimensional permanent magnets
Inventor: ABELE MANLIO G
IPC: G01R33/383
Filed: 1990-10-18
Abstract: ABSTRACT           A permanent magnet structure having at least one loop of circulating flux comprises a first and second plurality of uniformly magnetized prismatic: magnetic material sections (12, 14, 16, 18, 24, 26, 28, 30) forming a polygonal shaped cavity (20) and having a point F positioned along a zero equipotential base line (22) joining two vertices within the cavity, that point F being the reference for a figure of merit M corresponding to a maximum field strength and a minimum ratio of the value of the area of magnetized material to the area of the cavity (20). The first plurality of sections (12, 14, 16, 18) totally define the cavity (20) and have their respective remanences aligned to result in a total flux passing orthogonally through the base line. The second plurality of sections (24, 26, 28, 30) is oriented with respect to their respective remanences and the first sections (12, 14, 16, 18) so as to confine the flux within the cavity (20). A third plurality of nonmagnetized magnetic sec-tions (30, 32) encloses the base line (22) and borders the first sections (12, 14, 16, 18) for providing an inductive path to channel the flux and close the loop.

Title: Method and apparatus for measuring wind-related forces on a turning system
Inventor: BIZOT ALAIN
IPC: H02H7/085
Filed: 1992-06-25
Abstract: The invention is based on studies by the Applicant which have shown that the power delivered by the motors driving the system in rotation was dependent upon these forces. A measurement of the power, or of any quantity characteristic of this power (current, cos phi , pressure etc.) therefore enables the wind-related forces to be measured simply. If a limit value of power (or characteristic quantity) related to the limit wind speed beyond which the forces experienced by the system are too large is settled on, a condition relating to the operation of the motors is easily obtained through a comparison. 
<??>The invention also enables, in respect of rotating systems carrying out a measurement of angle, a correction to be made to this measurement.

Title: Method and apparatus for visual inspection of the internal structure of apparatus through internal passages
Inventor: DAILEY GEORGE F
IPC: G01M99/00
Filed: 1992-08-18
Abstract: The internal structure of an apparatus with internal passages such as a steam turbine is inspected without dismantling by inserting a compact robotic carriage device into a steam pipe and remotely controlling the carriage to carry a video probe to a restricted passage such as a nozzle block and to extend the probe relative to the carriage to inspect features within the restricted passage such as turbine blades. Separate motor drives for each side of the carriage include drive wheels of slightly greater diameter than a timing belt which serves as a tractor tread to drive the carriage over obstacles not bridged by the wheels. A large permanent magnet between the wheels is retained within the carriage by front and rear axles and secures the carriage to the pipe walls in all orientations.      The fixed size of the device is minimized by housing a motor for extending the probe relative to the carriage in a module cantilevered from the carriage by a preloaded compression spring. The single plane of articulation of the video probe is rotated by a torsion cable connected to the probe lead just behind the carriage.

Title: Distributed deuterium-lithium energy apparatus
Inventor: DREXLER JEROME
IPC: G21B3/00
Filed: 1991-05-17
Abstract: Method and apparatus for production of thermal energy through electrolyte ionization of heavy water using a lithium-6 OD  electrolyte, with dissolved deuterium gas in the heavy water, and pumping the ionized heavy water over a bed of palladium metal particulates (29), foils (47) or porous baffles (17) to collect both deuterium and lithium-6 ions to facilitate ion-ion combination. No electrodes are used to achieve the fusion process. The container is a closed system such as a loop (11) or helix (51) to permit continuous cycling of the ionized heavy water over the palladium ion collector again and again to absorb the maximum number of ions and to reuse the kinetic energy of the pumped water flow and the thermal energy added to the heavy water. Porous or perforated baffles are used to contain the palladium accumulator structure when it is in the form of particulates or loose components. Perforated baffles made of palladium may also be used as the accumulator structure.

Abstract: LD 10,172 SEAL CONSTRUCTION ARRANGEMENT FOR AN ELECTRODELESS HIGH INTENSITY DISCHARGE LAMP                  ABSTRACT OF THE INVENTION An electrodeless HID lamp having a quartz arc tube having a gas fill contained therein,  is energized to a discharge state upon the introduction of a high frequency RF current in close proximity thereto, also includes a starting aid stem which extends from the arc tube.   An outer jacket surrounds the arc tube and a portion of the starting aid stem.  The outer jacket is pinch sealed at the end from which the starting aid stem extends.  This pinch sealing results in the formation of a sealed space between the outer jacket and the arc tube and further allows that, by the gripping of the starting aid stem at the pinch seal region, the arc tube is supported in a fixed non-contacting position within the outer jacket.  A sealant material can be applied around the starting aid stem at the pinch seal region to prevent leakage of the sealed space formed within the outer jacket.
