Filed:

Nov 13, 2000

Appl. No.:

09/711285

Inventors:

Albert H. Wu - Medford NJ
James T. Wei - Glen Mills PA

Assignee:

Sunoco, Inc. (RM) - Philadelphia PA

International Classification:

C07C 266

US Classification:

585448, 585467

Abstract:

A zeolite-catalyzed cumene synthesis process in which benzene and propylene feedstocks are pre-treated to remove catalyst poisons. The benzene feedstock is pre-treated under pressure by contact with a âhotâ clay bed at a temperature of about 200 to 500Â C. , followed by distillation of the benzene feedstock to separate the benzene from the higher molecular weight materials formed from olefinic poisons during the hot clay treatment. The benzene feed is also subjected to a âcoldâ clay treatment wherein the benzene distillate is contacted with an ambient-temperature clay. The propylene feedstock is pre-treated by contact with an alumina to remove trace sodium compounds and moisture, a molecular sieve to remove moisture, and two modified aluminas to remove catalyst poisons. The pre-treated propylene and benzene feedstocks are then reacted in the presence of a zeolite catalyst to form cumene without causing rapid degradation of the catalysts activity.

US Classification:

369030860, 720718000

Abstract:

This invention is a mass storage system based on laser disc technology. While there are various laser discs players available, they are all aimed at serving an audio/visual entertainment purpose with no consideration given to the ability of this type of media to service the vast amount of data created in the information age. This invention will help users manage a vast laser disc collection, secure all information through backup, and make volumetric data truly portable.

Filed:

Sep 3, 2008

Appl. No.:

12/203147

Inventors:

Albert Taan Wu - Paramus NJ, US

International Classification:

F16M 13/00

US Classification:

248562, 2807281

Abstract:

The invention described is a controlled environment designed to house automotive onboard electronics. In general, the vibration and impact a moving vehicle experiences is detrimental to certain electronic components such as hard disk drives. Only the high-end automobiles that are equipped with elaborated shock absorbing devices may provide a suitable operating environment for these delicate electronics. Based on a completely different approach, this invention is to create a controlled space with a novel apparatus to reduce the shock and vibration within its domain regardless of what the automobile experiences. Therefore, the electronic components that reside inside this controlled space will experience far less severe impact thus enhance their chance of survival.

Appl. No.:

12/611868

Inventors:

Albert T. Wu - Paramus NJ, US

International Classification:

H02G 3/03
H01B 3/00

US Classification:

174 151, 174 17 R

Abstract:

A thermally controlled, anti-shock apparatus for protecting an automotive electronic device. The apparatus includes a first housing having sidewalls that define an interior cavity. A second housing having a reservoir containing fluid is disposed within the interior cavity of the first housing. A sealed housing for carrying the electronic device is disposed within the fluid in the reservoir of the second housing, wherein the fluid provides buoyancy for keeping the sealed housing at least partially afloat within the reservoir. The sealed housing includes an inner fluid impermeable bag for enclosing the protected electronic device and an outer fluid impermeable bag in which the inner bag and electronic device are disposed. A cooling system condenser includes condenser tubing connected to one or more heat dissipating members that are mounted on a thermally conductive panel using one or more high strength magnets.

Abstract:

A cargo container security system and method, including a cargo container with at least one sensor for detecting an open or closed status of a door on the cargo container and a geographic positioning locator for identifying a location of the cargo container. A control unit, located on the cargo container and operatively connected to the at least one sensor and geographic positioning locator, continuously receives historical data corresponding to at least the status of the cargo container door and location of the cargo container while the cargo container is in transit. The control unit assigns a timestamp to the received historical data, and stores the received historical data and associated timestamp in memory. A central computer system receives and analyzes the stored historical data for any anomalies upon the arrival of the cargo container at a destination. The central computer system generates an alert if an anomaly is identified.

US Classification:

568695

Abstract:

A process for production of diisopropyl ether by conversion of hydrocarbon feedstock containing propene, propane and C. sub. 2 - light gas components, including the steps of: optionally, prefractionating fresh feedstock containing propene, propane and C. sub. 2 - light gas components to provide a reactor feedstream rich in propene; contacting the feedstock and water in a catalytic reactor with acidic catalyst under olefin hydration and etherification conditions; and recovering from the catalytic reactor a liquid reactor effluent stream containing diisopropyl ether, isopropanol, water, unreacted propene, propane and C. sub. 2 - light gas components. Improved operation is achieved by separating the liquid effluent stream in a vertical stripper column; recovering an overhead vapor stream containing propene, propane and C. sub. 2 - light gas components from the stripper column; cooling the overhead vapor stream to provide a reflux stream rich in condensed propene and propane; removing the C. sub. 2 - light gas components from condensed; recycling the reflux stream to an upper contact portion of the stripper column; and recovering a predominantly C3 recycle stream from the upper contact portion of the stripper column.

Abstract:

An improved process for production of diisopropyl ether by conversion of hydrocarbon feedstock containing propene, propane and C. sub. 2 -- light gas components. The overall process steps include, (optionally) prefractionating fresh feedstock containing propene, propane and C. sub. 2 -- light gas components to provide a reactor feedstream rich in propene; contacting the feedstock and water in a catalytic reactor with acidic catalyst under olefin hydration and etherification conditions; and recovering from the catalytic reactor a liquid reactor effluent stream containing diisopropyl ether, isopropanol, water, unreacted propene, propane, oligomer and C. sub. 2 -- light gas components. DIPE product containing C. sub. 6 + oligomer is recovered by separating the liquid effluent stream in a stripper column, and extracting the DIPE-rich liquid with water.
