Patent CA-2923430-A1 (CA)
Title: Tunable progressive cavity pump
Inventor: GUNTER SHAWN N
IPC: F04D13/08
Filed: 2014-09-16
Abstract: A well pump assembly includes a progressive cavity pump having a stator with an elastomeric inner portion. The stator has an axial cavity with internal lobes; a rotor with external lobes positioned within the axial cavity. An effector selectively increases and decreases a stiffness of the stator by changing a cross sectional area of the axial cavity in the stator. The effector may include a reservoir within the stator containing a fluid. A reservoir pump selectively increases and decreases a pressure of the fluid in the reservoir in response to sensing the flow rate from the progressive cavity pump and the torque of the motor. Alternately, the reservoir may contain a magneto-rheological fluid (MR fluid). A coil generates an electromagnetic field within the MR fluid to selectrively increase and decrease a viscosity of the MR fluid.

Abstract: When a roof tile provided with a hole is manufactured, first a non-cured composition 11 is fed between two facing mold surfaces 13b and 15b of two mold halves 13 and 15 after which the two mold halves are brought together. The mold surface 13b of one of the two mold halves 13 is provided with a bulge 17 which has a thickness 19 that is smaller than the distance 21 between the two mold surfaces 13b and 15b at the location of this bulge in the state of the mold halves brought together. As a result, the roof tile obtains a thin part 23 at the location of this bulge 17. After the pressing operation the two mold halves 13 and 15 are taken apart and the composition 11 is cured. Once the roof tile 1 has cured, the thin part 23 is broken away from the roof tile and in this manner the hole 5 in the roof tile is formed.

Filed: 2015-06-17
Abstract: An approach to noninvasively and remotely detect the presence, location, and/or quantity of a target substance in a scene via a spectral imaging system comprising a spectral filter array and image capture array. For a chosen target substance, a spectral filter array is provided that is sensitive to selected wavelengths characterizing the electromagnetic spectrum of the target substance. Elements of the image capture array are optically aligned with elements of the spectral filter array to simultaneously capture spectrally filtered images. These filtered images identify the spectrum of the target substance. Program instructions analyze the acquired images to compute information about the target substance throughout the scene. A color-coded output image may be displayed on a smartphone or computing device to indicate spatial and quantitative information about the detected target substance. The system desirably includes a library of interchangeable spectral filter arrays, each sensitive to one or more target substances.

Title: Real-time, multi-array sum power spectrum control
Inventor: HUSS ANDREW D
IPC: G01S13/87
Filed: 2015-07-30
Abstract: Power control (104, 300) for a radar system (100) issues power draw commands to each array (102a-102d) in the radar system. Each power draw command controls direct current (DC) power draw by the respective radar array on a dwell-by-dwell basis, based on total energy resources (including stored energy) available to the respective array at the start of a dwell period, a power spend rate expected for the respective array during the dwell period, and a rate of "waste" power set to be dispersed to reduce excess power at the respective array during the dwell period. In determining power draw for an array, the power control takes into account a predetermined number of future dwell periods and any transmit and/or receive tasks scheduled for such periods. If necessary to maintain less than a predetermined ripple on total DC power drawn from a source of the DC power by the radar system, the power control adjusts a duration of empty dwell periods within the dwell schedule (301) for one or more of the arrays.

Abstract: A hydropyrolysis process comprises feeding both (i) hydrogen and (ii) a biomasscontaining feedstock or a biomass-derived feedstock, to a hydropyrolysis reactor vessel. The process comprises producing a CO2-containing vapor stream and at least one liquid product. A CO2 product, separated from the CO2-containing vapor stream, is advantageously used for at least one inertization function of the hydropyrolysis process. Representative inertization functions include operation of solids transport equipment, blanketing of liquid containers, drying of biomass-containing feedstock or biomass-derived feedstock, conveying or separating solids, and combinations thereof. Importantly, CO2 products utilized for these inertization functions may be obtained predominantly, if not completely (depending on the nature of the feedstock), from renewable carbon in biomass.
