Abstract: A carrier-gas mixture is directed through a fluid flow path (16, 18) in a combined heat and mass transfer device (12, 14), which can be operated at sub-atmospheric pressure. Heat and mass are transferred from/ to the carrier-gas mixture via interaction with a liquid composition including a vaporizable component in a liquid state to substantially change the content of the vaporizable component in the carrier-gas mixture via evaporation or condensation. The mass flow rate of the carrier-gas mixture is varied by extracting/injecting (60, 62, 64) the carrier-gas mixture from at least one intermediate location in the fluid flow path, and/or the mass flow rate of the liquid composition is varied by extracting/injecting the liquid composition from at least one intermediate location in the fluid flow path. The flow of the carrier-gas mixture or the liquid composition is regulated to reduce the average local enthalpy pinch.

Abstract: A method for making gravel filters in oil well bores. The first step involves ascertaining the location of a producing formation adjacent to a cemented casing in a well bore. Then, a portion of the casing adjacent to the producing formation is cut, enlarging the bore adjacent to the producing formation. Subsequently, a sufficient amount of gravel is deposited in the enlarged portion of the bore to create an effective filter for a producing tube with a screen at its distal end. The distal end is positioned adjacent to the cemented bottom of the well bore. The method maximizes the diameter of the gravel deposited by delivering it exteriorly of the screen of the producing tube and through the annular space defined and sealed between the screen and the casing.

Abstract: A filter assembly for a fluid filter includes a plurality of filter units assembled in series, and each filter unit includes: a connecting member, an input member and an output member. The input member of each of the filter units has an extending pipe connected to a connecting pipe of another filter unit, so that the filter units can be easily assembled by directly screwing the connecting pipe of the connecting member of one filter unit into the extending pipe of the input member of another filter unit, without using tools or fasteners. Hence, the assembling cost is relatively reduced.

Abstract: Undesirably high energy-consumption in illuminating devices can be caused at least in part by wasted (attenuated) light. Optically efficient illumination systems that may be used to project light, including images, use light redirection. Phase modulating devices may be applied to create desired light fields. Some embodiments provide dual or multiple modulation display or projection systems in which some or all of the modulators not only attenuate amplitude, but also amplify amplitude, or change the phase, frequency and polarization of the light provided by the light source.

Title: Hybrid electric motor with self aligning permanent magnet and squirrel cage rotors
Inventor: FINKLE LOUIS
IPC: H02K16/02
Filed: 2015-01-08
Granted: 2023-09-05
Abstract: A hybrid induction motor includes a fixed stator, an independently rotating outer rotor, and an inner rotor fixed to a motor shaft. In one embodiment the outer rotor includes spaced apart first bars and permanent magnets, and the inner rotor includes spaced apart second bars. In another embodiment the outer rotor includes angularly spaced apart first bars but no permanent magnets, and the inner rotor includes permanent magnets and may also include angularly spaced apart second bars. The outer rotor is initially accelerated by cooperation of a rotating stator magnetic field with the first bars. As the outer rotor accelerates towards synchronous RPM, the inner rotor is accelerated to transition to efficient synchronous operation.  The outer rotor thus acts as a clutch to decouple the inner rotor from the rotating stator magnetic field at startup and to couple the inner rotor to the rotating stator magnetic field at synchronous speed.

Abstract: In a sludge thickener water/wastewater treatment system, sludge solids are recirculated with a mixer positioned in the influent column or offset from the center column and within the stilling well, in order to produce essentially constant sludge solids concentration in the sludge withdrawn from the thickener. This solves the problem of thickeners producing inconsistent underflow solids concentration and often exhibiting problems with binding of rake arms due to sometimes very high sludge concentrations. Also, dewatering steps that follow thickening typically require a relatively constant solids concentration for efficient operation.
