Abstract: An improved threaded joint for connecting a first tubular member, for example a valve housing, with an outer end having interior threads with pitch W and terminating in a shoulder. A second tubular member has an exterior threaded end and a flanged end. A shoulder extends outwardly of the second tubular member intermediate the threaded and flanged ends. A flange at the flanged end has N equally circumferentially spaced connectors. One of the first shoulder and second shoulder includes a portion that is elastically deformable over a distance at least equal to W/N so that connectors in the flange may be aligned with connectors in a connecting flange of a pipe line. A side entry cap is disposed in the valve assembly. The side entry cap includes a threaded portion and a sealing portion inward of the threaded portion, the threaded portion being cylindrical and the sealing portion having an exterior surface forming a conical section increasing in diameter outward. The valve assembly has a corresponding conical seat portion for receiving the conical section of the side entry cap in sealing relationship. An annular groove is formed in one of the conical section of the sealing portion and the conical seat portion of the valve assembly, the annular groove being defined by walls extending inward from the respective one of the conical section of the sealing portion and the conical seat portion of the valve assembly. An annular sealing element is disposed within the annular groove.

Abstract: A programmable synchronizing system for selectively providing synchronizing signals at different rates, such as for incorporation in a video signal decompression system, includes an oscillator and a programmable counter. The programmable counter is conditioned to count pulses from the oscillator by alternate moduli in predetermined sequences to generate the synchronizing signals. The desired synchronization rate is effectively the average of the counter output resulting from counting by the alternate moduli.
Patent CA-2194836-C (CA)

Granted: 2001-09-11
Abstract: An efficient, lossless, continuous-resolution representation (the "PM representation") of highly detailed geometric models for computer graphics specifies a succession of progressively more detailed polygonal meshes (i.e., "progressive meshes") as a base polygonal mesh and a sequence of complete mesh refinement transformations (e.q. , the vertex split transformation) that approximate the model at progressively finer levels of detail. Procedures for storing and transmitting geometric models using the PM representation address several practical problems in computer graphics: smooth geomorphing of level-of-detail approximations, progressive transmission, mesh compression, and selective refinement. An optimized mesh simplification procedure constructs the PM representation of a model from an arbitrary polygonal mesh, while preserving the geometry of the original mesh as well as its overall appearance as defined by its discrete and scalar appearance attributes such as material identifiers, color values, normals, and texture coordinates. In particular, the PM representation and these procedures preserve discontinuity curves such as creases and material boundaries of the geometric model.

Abstract: An incubation station has a carousel for receiving a plurality of test sample cards. An even temperature and air flow distribution inside the carousel and incubation of the cards over time at the proper temperature was found to be critically dependent upon air flow characteristics within the incubation station. To optimize air flow, the carousel was given an open rear side that is exposed to an air distribution table having a cover plate placed adjacent to the rear surface of the carousel. The cover plate has a plurality of elongate slots positioned in a symmetrical ring-shaped pattern in registry with the carousel. The elongate slots are positioned at an angle relative to the slots in the carousel such that each carousel slot receives air from more than one slot. An extra fan was also added to the system to increase the flow of air into the air table. Scallop features on the carousel walls also promote even distribution of air flow over the cards. The carousel may be divided into a plurality of carousel segments to increase ease of removal and insertion of the carousel into the incubation station and manufacturability of the carousel.
