Appl. No.:

12/647334

Inventors:

Victor S. IVASHIN - Santa Rosa CA, US
John W. Webley - Santa Rosa CA, US

International Classification:

E05B 65/00
G08B 13/00

US Classification:

70 91, 3405451

Abstract:

A method and apparatus for monitoring the security of closures of the type used on large trucks, and shipping or other containers wherein one or more doors are provided on an end and/or the sides of the container and are secured by vertical rods having cam-like latches at their ends that are rotatable from a first disposition in which they engage keepers to lock the doors in a closed position, and a second disposition in which they disengage the keepers to unlock the doors and allow them to swing into an open position. More specifically, the present invention relates to a monitoring assembly that attaches between the locking rod handles of the containers, senses any movement of the locking handles or the opening of the doors, and provides visual signals and/or transmitted signals as an indication of tampering.

US Classification:

210644, 210182

Abstract:

Improved systems and processes for forward osmosis water purification or desalination are herein disclosed. According to one embodiment a process for purifying contaminated water is provided wherein a contaminated feed solution stream comprising water and with a first osmotic pressure is passed through a semipermeable membrane to a draw side having a draw solution stream with a second osmotic pressure on a draw side of the semipermeable membrane. The diluted draw solution stream is heated, agglomerated and cooled to produce a cooled single phase water rich stream that is purified to produce a water product stream.

International Classification:

F28D 7/02
F28F 21/06

Abstract:

Polymeric tube-in-shell heat exchangers with twisted tubes are provided. The heat exchanger may include one or more polymeric tube bundles, wherein each of the one or more polymeric tube bundles includes at least one tube twisted about its length or at least one pair of tubes twisted or wound around each other. The presently disclosed polymeric tube-in-shell heat exchangers with twisted tubes may be especially suited for applications where the use of polymer tubes offers advantages, such as in the case of acid solutions, food and beverage fluids, and carbon capture applications where the use of metal heat exchangers destroy the amines used for capture.

Abstract:

Membranes and filtration modules for producing a concentrated feed stream and a diluted feed stream during operation in a water purification or wastewater treatment system. Filtration modules are provided that include a semipermeable membrane having a first side and a second side, the first side configured to receive a first feed solution stream from a first feed solution source and the second side configured to receive a second feed solution stream from a second feed solution source. The semipermeable membrane may be configured to operate at a hydrostatic pressure on the second side of the membrane from about 1% to about 40% of the hydrostatic pressure on the first side of the membrane, and may in some cases exhibit a salt rejection of from about 60 percent to about 90 percent during operation.

B01D 61/58

Abstract:

Draw compounds and draw solutions comprising said draw compounds for use in forward osmosis solvent purification systems. The draw compound may be a linear random, sequential, or block molecular chain consisting of at least one oxide monomer or diol monomer and have a temperature-dependent affinity with a feed solvent. The draw compound may further include a first terminal group and a second terminal group, at least one of the first terminal group and the second terminal group selected from the group consisting of a hydroxyl group, an amine group, a carboxylic group, an allyl group, and a C1 to C14 substituted and unsubstituted alky group. The draw compound may also be a branched random, sequential, or block molecular chain consisting of at least one oxide monomer or diol monomer.

Abstract:

Devices, methods, and systems for producing a concentrated feed stream and a diluted feed stream using a solute stream provided to the low pressure side of the semi-permeable membrane during a reverse osmosis process. The process includes providing a semipermeable membrane having a first side and a second side and introducing a first feed solution stream on the first side of the membrane and a second feed solution stream on the second side, wherein the osmotic pressure of the of the first feed solution stream is greater than or equal to the osmotic pressure of the second feed solution stream. The process further includes exerting hydrostatic pressure on the first side of the membrane such that solvent passes from the first side to the second side thereby producing a concentrated first feed solution stream and a diluted second feed solution stream. Devices and systems for performing the processes are provided.
