Patent number: 5171455Abstract: Small quantities of one or more liquids having a low boiling point dispersed with a large quantity of one or more immiscible liquids having a higher boiling point are separated in a rapid and efficient manner. A non-reactive gas (nitrogen, helium, air, or combinations thereof) is heated by recycled energy and make-up energy to a temperature above the boiling point of at least one liquid but below that of at least one other liquid. The heated gas is combined with the unheated or preheated liquid-liquid mixture to be separated, and the liquid-gas blend is mixed, heated and distributed by an improved heat exchanger having thermal conductive gas tubing, metal wools and fins) and nebulizer, forming a mist inside a vessel containing a pool liquid of at least one liquid having a boiling point higher than that of at least one other liquid, which pool liquid has been heated with at least a heat pump means to a temperature above the boiling point of at least one liquid but below the pool liquid's own boiling point.Type: GrantFiled: July 10, 1992Date of Patent: December 15, 1992Assignee: International Environmental Systems, Inc.Inventors: Lawrence K. Wang, Roland E. Weber, John J. Pavlovich

Patent number: 5156747Abstract: Small quantities of one or more liquids having a high boiling point dispersed with a large quantity of one or more immiscible liquids having a lower boiling point are separated in a rapid and efficient manner. A non-reactive compressed gas is heated by recycled energy and make-up energy to a temperature above the boiling point of at least one liquid but below that of at least one other liquid. The heated gas is combined with the unheated liquid mixture to be separated, and the liquid-gas blend is mixed, heated and distributed by an improved nebulizer, forming a mist inside a vessel containing a pool liquid of at least one liquid having a boiling point higher than that of at least one other liquid, which pool liquid has been heated to a temperature above the boiling point of at least one liquid but below its own boiling point. The liquid having high-boiling-point in the mist settles by gravity and merges with the pool liquid.Type: GrantFiled: October 18, 1991Date of Patent: October 20, 1992Assignee: International Environmental Systems, Inc.Inventors: Roland E. Weber, Lawrence K. Wang, John J. Pavlovich

Patent number: 5076268Abstract: Blood flow in the aorta and pulmonary artery of a mammal, most typically a human, is measured volumetrically be a non-invasive, ultrasound apparatus. The apparatus (10) comprises a tracheal tube or probe with of flexible tubing (11) having a transducer assembly (21) mounted at one end the tube. The transducer assembly (21) is disposed to transmit ultrasound in selected directions. Electrical conductors (24) extend the length of the probe from the transducer assembly. Improved means is provided to positively locate the probe in the trachea and to urge the ultrasound transducer assembly (21) into intimate contact with the inner wall of the trachea.Type: GrantFiled: November 22, 1989Date of Patent: December 31, 1991Assignee: Applied Biometrics IncorporatedInventor: Roland E. Weber

Patent number: 4973404Abstract: A filtration apparatus characterized by efficiency of the precoating step and maintenance of filtration performance over a long period of time after precoating has been completed. The filter promotes parallel flow of porous precoat material along a porous septum, thereby achieving efficient stacking of this material against the septum. A dual-speed pumping system transmits the precoat material to the septum at high velocity, thereby further encouraging efficient stacking, but pumps the fluid to be filtered at a lower velocity to minimize energy consumption.Type: GrantFiled: September 5, 1989Date of Patent: November 27, 1990Assignee: Aurian CorporationInventors: Roland E. Weber, John J. Pavlovich, Lawrence K. Wang

Patent number: 4165283Abstract: The present invention relates to a multi-stage, single vessel, purification system for removing solid particles from liquids.Within the central portion of the vessel is a deceleration chamber having flow control means. About and substantially coextensive with the deceleration chamber is a filtering chamber. Depending well into the filtering chamber are a plurality of septums preferably coated with filter aid. Below the deceleration and filtering chambers is a settling chamber, and beneath the vessel is an expulsion device.A contaminated liquid is fed into the deceleration chamber and decelerated. In this chamber the lighter solid particles rise to the top of the liquid where they are removed, while the heavier density particles settle downwardly. As the liquid moves downwardly from the deceleration chamber it essentially displaces liquid in the settling chamber upwardly into the filtering chamber. In so doing the change of direction of liquid movement also causes the heavier particles to settle downwardly.Type: GrantFiled: March 29, 1977Date of Patent: August 21, 1979Assignee: Industrial Pollution Control Corp.Inventors: Roland E. Weber, Carl J. Zimmermann
