Inventor: GRAY BUDDY DON
IPC: B01D17/12
Filed: 2002-01-09
Abstract: A pump system for tangential flow and cross-flow filtration systems, such as reverse osmosis, nano, and micro filtration systems, that independently fixes the percent of recovery of product water for each stage and recovers the energy normally lost in rejected waste streams. The pump (10) is positive displacement and fixes the recovery by establishing set ratios between the feed water inlet and reject stream volume of each stage of the filtration system while using the same ratio setting components to recover the energy normally expelled in reject, or concentrate, waste streams. The ratios are set by having cylinder bores (13(A-F)) of decreasing volume with associated pistons (14(A-F)) that reciprocate therein to move the fluid. The pump (10) aids in conservation of water by allowing efficient multi-stage reprocessing of the concentrate streams from all but the final stage of processing.

Title: Method and apparatus for evaporating multi-component liquids
Inventor: SCHRAMM HEATHER R
IPC: B05B17/06
Filed: 2003-02-04
Abstract: An atomizer 10 atomizes a multi-component liquid from a reservoir 20 into a cloud 14 comprising small droplets 38 which are ejected into the atmosphere to a certain height and allowed to fall toward a surface 12. Essentially complete evaporation is assured by maintaining the size of the droplets, the liquid's component vapor pressures and the height through which the droplets fall according to a predetermined relationship. Also, the suitability of a liquid for evaporation in a vibrating plate atomizer is determined by measuring the rate of size decrease and the surface tension of a pendant drop of the liquid after a predetermined amount of the liquid has evaporated from the drop.

Abstract: A system and method (32) for measuring line-of-sight angular rates for all-weather precision guidance of distributed projectiles (16) and a guidance system (10) based thereon. In accordance with the novel method (32) for measuring line-of-sight angular rates, first the range rates of the target (14) relative to at least two projectiles (16) is determined, as well as the position and velocity of each projectile (16). Then, the line-of-sight angular rate of the target (14) relative to at least one projectile (16) is computed from the range rates, positions, and velocities. In the illustrative embodiment, the range rate of the target (14) relative to a projectile (16) is determined based on a monostatic target Doppler measurement, a monostatic projectile Doppler measurement, a bistatic Doppler measurement of the target (14) by the projectile (16), and the carrier frequency of a data link (26) between the projectile and the shipboard system. The guidance system (10) of the present invention includes a monostatic radar (18) illuminating the target (14), bistatic receivers (44) aboard at least two projectiles (16) fired at the target (14), and a system (32) for determining line-of-sight angular rates to the target based on the monostatic measurements and the bistatic measurements from at least two projectiles. The guidance system (10) further includes a system (34) for computing guidance command signals for at least one projectile based on the line-of-sight angular rates, and a projectile steering unit (52) aboard at least one projectile for steering the projectile based on the guidance command signals.

IPC: G01N30/60
Filed: 2003-03-21
Abstract: A rigid base (3) defines an axis (X). An abutment (4) forms a resting surface (5) for one end of the long component (2) and a retainer (6). These components (4, 6) are axially separated by a detachable support block with a through passage (8) for sliding adjustment and housing of part of the long component (2). It can be positioned and held between the retainer and the abutment, making surface contact against the abutment. An axially-guided moving component (9) has a second component (10) contacting the other end of the long component (2).  The moving component (9) is articulated with two links (11, 11'). These rotate on eccentrics (12, 12'), which pivot on the base (3). They are assembled rigidly with a pivoting cover (13). This swings down over the assembly (4, 6, 9) and the components (5, 7, 10), corresponding with the locked state of the long component. The two eccentric assemblies (12, 12') and links (11, 11') transform the pivoting movement of the cover (13) into translation of the moving component (9).
