Patent CA-3020052-A1 (CA)
Title: Low inlet vorticity impeller having enhanced hydrodynamic wear characteristics
Inventor: ECHEVERRI LUIS
IPC: F04D29/24
Filed: 2017-04-06
Abstract: Provided are non-limiting embodiments of a wear-resistant impeller having a non- conventional blending provided between a surface of a vane and a surface of at least one of a front side shroud and a rear side shroud. The impeller may comprise both a rear side blending and a front side blending, and the front side blending may comprise a different geometry from the rear side blending. The blending preferably comprises a bulbous geometry which is uniquely adapted for optimizing flow patterns adjacent to the vane and between the front and rear side shrouds in a manner which discourages the formation of horseshoe vortices proximate the leading edge of the vane during operation. Through the reduction, mitigation, or elimination of horseshoe vortices, local high velocities and turbulence are generally minimized, and wear experienced by portions of the impeller (e.g., to one or more vanes) from flows of abrasive slurry can be reduced. Accordingly, the useable life of an impeller may be improved.

Filed: 2017-06-02
Abstract: In order to provide oxide particles with controlled color characteristics, the present invention provides a manufacturing method for oxide particles, which is characterized in that color characteristics of the oxide particles are controlled by controlling the M-OH bond / M-O bond ratio, which is the ratio of M-OH bonds that are bonds between M and oxygen (O), to M-O bonds that are bonds between M and a hydroxyl group (OH), where M is oxygen or one or multiple different elements other than hydrogen contained in oxide particles selected from metal oxide particles and metalloid oxide particles. With the present invention, it is possible to provide oxide particles in which color characteristics such as reflectance, transmittance, molar extinction coefficient, hue or saturation are controlled by controlling the M-OH bond / M-O bond ratio of the metal oxide particles or metalloid oxide particles.

Patent CA-3038622-A1 (CA)
Inventor: PANTHER GYLES
IPC: H01Q19/28
Filed: 2019-04-01
Abstract: Global navigation satellite system (GNSS) radio frequency signals broadcast from geo-stationary satellites 20,000 km above the earth when received by GNSS receivers are fundamentally weak. Accordingly, these GNSS receivers are vulnerable to accidental and deliberate interference from a range of manmade sources as well as natural sources. Existing anti-jamming technologies such as controlled reception pattern antennas, adaptive antennas, null-steering antennas, and beamforming antennas etc. are expensive and incompatible with many lower cost and footprint limited applications. However, in many applications the GNSS antenna is mounted upon a fixed or mobile element such that accidental and intentional jammers tend to be in the plane of the antenna or below it. Accordingly, there are presented designs and techniques to improve the anti-jamming or interference performance of GNSS receivers by further reducing the responsivity of the GNSS receiver to signals in-plane or below the plane of the antenna.
