Patent CA-2252322-A1 (CA)
Title: Spin-on filter with improved retaining groove
Inventor: BIERE DAVID A
IPC: B01D35/02
Filed: 1998-11-03
Abstract: A spin-on filter including an improved baseplate preferably die cast from aluminum provides an inventive outer gasket retaining groove. The baseplate comprises a hub joined to a rim by ribs. The rim provides a generally cylindrical wall and a seating surface extending radially outward therefrom. The cylindrical wall defines an inner vertical wall for the outer gasket retaining groove. Horizontal ribs extending from the top of the wall provides inventive retaining means for securing and aligning an outer gasket in the retaining groove. The inventive baseplate can be used in filters with or without a seaming lid. The present invention improves the fastening technique for both types of aluminum in the baseplate filters.

Title: Procede de commande d'appel
Inventor: HAUMONT SERGE
IPC: H04M15/00
Filed: 1998-02-26
Abstract: Dans certains systèmes de télécommunication mobiles, la réception des appels à l'extérieur du réseau de rattachement peut être très coûteuse pour l'abonné appelé. Pour cette raison, les abonnés ont la possibilité d'interdire les appels entrants quand ils sortent de leur réseau de rattachement. Par ailleurs, avec un acheminement optimisé, la réception des appels, même loin dudit réseau, peut être très avantageuse, voire gratuite. Il n'y a donc plus de raison pour interdire les appels entrants. L'invention concerne un procédé selon lequel ces éléments du réseau peuvent être définis pour l'abonné sur la base des informations de localisation à partir desquelles les appels entrants peuvent lui être transmis.
Patent CA-2283045-A1 (CA)
Title: A method and system for environmental sensing and control within a computer system
Inventor: SHEMPERT CRAIG H
IPC: G06F11/30
Filed: 1999-09-23
Abstract: In accordance with the method and system of the present invention, a local processor utilizes registers arranged in a fault/mask/cache fashion for environmental control and sensing within a data processing system. The local processor continuously reads input data from a variety of environmental sensors in order to determine if a threshold level has been reached and a fault condition exists. Cache registers allow the local processor to store/pass detailed sensor information to system firmware within system processor(s). The local processor sets a fault bit within a fault register designed to cause an interrupt to the system level firmware if any of its bits are non-zero, indicating that a fault condition has occurred. A mask register is designed to allow the interaction of both the local processor and system processor(s) when an interrupt is being serviced and help keeps track of which interrupts are being serviced and which are yet to be serviced in the case of multiple interrupt sources. The system firmware will service the interrupt and set the mask bit. The action will signal the local processor that the system has acknowledged the interrupt and will take the appropriate action. The local processor may now post another fault, exactly like the first fault, by clearing the mask bit and causing a subsequent interrupt to the system. The fault, mask, cache, and both local and system processor(s) work together to provide a positive interlock for synchronizing their actions with each other.

Title: Steering arms and railway car trucks with improved access to brake shoe keys and method of changing brake shoes
Inventor: ANDERSON NORMAN G
IPC: B61F5/38
Filed: 1999-09-27
Abstract: A steering arm assembly for use with railway car trucks having pivotal frames and brake systems is disclosed. The steering arm assembly has two U-shaped sub-assemblies. Each sub-assembly has two side arms connected by a center arm. The side arms each have vertical open paths between top and bottom holes in their surfaces and open side paths through side access holes in their sidewalls. The open side paths intersect the vertical open paths. The vertical open paths are positioned to be aligned over the brake system brake shoe keys and the side access holes are positioned to be aligned with the side windows in the side frame. When it is desired to remove or replace a brake shoe, the brake shoe key may be moved upwardly through the vertical open path. This movement may be facilitated through use of a tool inserted through the side access hole and open side path in the side arm. A  method of changing brake shoe keys and the combination of such a steering arm assembly in a railway car truck is also disclosed.
Patent CA-2286828-A1 (CA)
Inventor: TAYLOR PATRICK R
IPC: H01F1/11
Filed: 1999-10-18
Abstract: Substantially spherical magneto-plumbite ferrite (barium or strontium ferrite) particles are formed from well-dispersed ultra-fine substantially spherical iron-based oxide and/or hydroxide particles as precursor particles. The precursor particles are mixed with a colloidal barium or strontium carbonate (BaCO3 or SrCO3), and with small amounts of a byproduct, such as sodium or potassium chloride (NaC1 or KC1) or hydroxide (NaOH or KOH) or nitrate (NaNO3 or KNO3), functioning as a flux to lower the calcination temperature. The particles are filtered out of the mixture, dried, and calcined for a time sufficiently long and/or at a temperature sufficiently high to form magneto-plumbite ferrite from the precursor particles, and for a time sufficiently short and/or a temperature sufficiently low to maintain the general spherical shape of the precursor particles. The particles are used for forming a magnetic recording media by dispersing the particles in a magnetic paint and coating the paint onto a substrate, or by dispersing the particles in a self-supporting material.
Patent CA-2286902-A1 (CA)
Title: Three-dimensional imaging method and device
Inventor: RIOUX MARC
IPC: G01B11/245
Filed: 1998-04-07
Abstract: A three-dimensional imaging method and device including a ranging sensor that is used to produce a series of profiles of a target surface. The profiles comprise one set of profiles nearly parallel to each other and a further such set of nearly parallel profiles, with the profiles of one set extending at an angle to those of the other set to generate a large number of profile crossings. At the location of each crossing the shortest distance between the profiles is detected and represents an energy contribution between this pair of profiles.  An energy function is defined as the sum of the energy contributions of all the crossings. Using a known mathematical model, the profiles are then reoriented relative to each other in such a manner as to minimise this total energy. This process can be repeated for highter precision. The finally reoriented profiles can be used to define the desired three-dimensional shape of the target surface.
