Patent CA-2269570-A1 (CA)
Inventor: VANDE SANDE JERRY W
IPC: B61D7/32
Filed: 1999-04-21
Abstract: A large capacity car body for a pressure discharge railway hopper car has a plurality of end slope plates assemblies, each having a slope sheet; and a plurality of intermediate slope sheet units, each of inverted "V" shape. The intermediate slope sheet units and the end slope plates form the end walls of a plurality of hoppers. A crossridge frame is associated with each of the intermediate slope sheet units and together with the end frames supports side sheets and a top sheet. Top chord members and bottom chord members extend coextensively with and are welded to upper and lower edge portions of each side sheet. Edge portions of the top sheet overlap and are welded to upper leg portions of the two top chord members. The crossridge frames and chord members considerably increase the resistance of the side sheets and top sheet to deforming when the car body is pressurized during unloading. The sides and the top of the of the car body are curved in end profile, the sides having radii of about eleven feet and the top a radius of about seven feet. The overall width of the car is about ten feet, eight inches, and the top sheet has a span of about eight feet, five inches. The curvatures of the side and top sheets and the overall dimensions provide the car body with added capacity in the upper and lower corners, as compared with a car body having a substantially circular cylindrical end profile.

Abstract: Polymer-bound adsorbent beads are usable as a direct replacement for conventional clay-bound beads in insulating glass unit manufacture to eliminate the problem of dusting associated with conventional beads. Polymer-bound beads provide good adsorption and superior crush strength compared to clay-bound adsorbent beads previously used in insulating glass units to desiccate the space between the glass panes. The polymer-bound adsorbent beads may also be used as a substitute for conventional desiccant beads in water adsorption applications such as in bottle stoppers, sachets, blister packaging, etc.

Patent CA-2288118-A1 (CA)
Inventor: GOLDEN ROBERT N
IPC: A61B19/00
Filed: 1998-05-08
Abstract: A device to detect the location of a magnet coupled to an indwelling medical device within a patient uses three or more sets of magnetic sensors each having sensor elements arranged in a known fashion. Each sensor element senses the magnetic field strength generated by the magnet and provides data indicative of the direction of the magnet in a three-dimensional space. The device uses fundamental equations for electricity and magnetism that relate measured magnetic field strength and magnetic field gradient to the location and strength of a magnetic dipole. The device uses an iterative process to determine the actual location and orientation of the magnet. An initial estimate of the location and orientation of the magnet results in the generation of predicted magnetic field values. The predicted magnetic field values are compared with the actual measured values provided by the magnetic sensors. Based on the difference between the predicted values and the measured values, the device estimates a new location of the magnet and calculates new predicted magnetic field strength values. This iteration process continues until the predicted values match the measured values within a desired degree of tolerance. At that point, the estimated location matches the actual location within a predetermined degree of tolerance. A two-dimentional display provides an indication of the location of the magnet with respect to the housing of the detector. A depth indicator portion of the display can be used to provide a relative or absolute indication of the depth of the magnet within the patient.

Title: A linear programming method of network design for carrying traffic from endnodes to a core network at least cost
Inventor: ZHANG YIHAO LISA
IPC: H04L12/24
Filed: 1999-11-25
Abstract: A method is disclosed, for designing an access network that is to carry communication traffic between end nodes and a core network. Information is provided that describes end node locations, the level of demand associated with each end node, available trunk types and their related capacities, and a cost structure. The cost structure includes a fixed overhead cost for each trunk type, and a service charge per unit distance for each trunk type. The provided information is incorporated in a linear program to find an optimal-cost access network. The linear program is solved to obtain a provisional solution that defines the composition and usage of each link of the optimal-cost access network. For each such link, the composition is defined by a fractional level of investment (incurring a like fraction of the corresponding overhead charge) in each pertinent trunk type. The provisional solution is rounded such that each trunk in which there is a fractional investment is either removed, or replaced by a trunk in which there is an integral investment.

Filed: 1998-06-19
Abstract: A split-band coding system combines multiple channels of input signals into various forms of composite signals and generates spatial-characteristic signals representing soundfield spatial characteristics in a plurality of frequency subbands. The spatial-characteristics signals may be generated in either or both of two forms. In a first form, the signal represents measures of signal levels for subband sig-nals from the input channels. In a second form, the signal represents one or more apparent directions for the soundfield. The type of the spatial-characteristics signal may be adapted dynamically in response to a variety of criteria including input signal characteristics.    Temporal smoothing and spectral smoothing of the spatial-characteristics signals may be applied in an encoder. Temporal smoothing and spec-tral smoothing may be applied to gain factors derived from the spatial-characteristics signals in a decoder.

Abstract: In a processing satellite, it is customary to provide a control processor to manage the overall operation of the processing suite and to provide a central point of interaction for: reception of and reaction to control directives from the ground, gathering of statistics, formatting and sending of reports on the processing activity, et cetera. The controller relates to a structure that permits an ensemble of independent constituent processors to operate as a coordinated whole to achieve the overall control processing function with robustness to failure of the constituents. This robustness is realized by: (a) the use of redundant constituent processors; (b) the interconnection of the ensemble by a dual redundant bus structure; (c) a distributed and loosely coupled unifying control method. Each constituent processor is able to take on a portion of the tasks of another constituent processor in the event of failure. The ensemble is coordinated on an ensemble basis to provide a loosely coupled form of overall control and to avoid the risk of a single point of failure.
