Filed:

Jan 12, 2000

Appl. No.:

09/481583

Inventors:

David William Birch - Whitehill, GB
Peter Harold Buckley - Carlsbad CA
Kenneth William Cross - Cardiff CA
Richard A. Hogle - Oceanside CA
Kazuya Inoue - Shanghai, CN

Assignee:

The BOC Group plc - Windlesham

International Classification:

F16K 100

US Classification:

251319, 251331

Abstract:

A valve for use with an ultra high purity gas comprising a valve body defining a valve chamber having a valve outlet through which gas is discharged and containing a reciprocable sealing member, characterized in that the valve chamber is in fluid communication with a source of the gas and in that the sealing member is reciprocable along an axis substantially parallel to the direction of flow of gas discharged from the valve outlet and into and out of sealing contact with a sealing face located within the valve chamber and circumscribing the inlet end of a valve outlet pipe, the opposite, outlet end of which pipe forms the valve outlet. The valve has a low wetted area and is thus easy to purge, and the valve design both reduces wear and restricts it to a single component which is easily replaced when necessary.

Kenneth Cross - Cardiff CA, US

International Classification:

B01D 35/06
B03C 1/02

US Classification:

210695, 210222, 210223, 977902, 42218601, 204155, 204557, 204660, 204664

Abstract:

What is presented is an innovative design of a chemical reactor for catalytic breakdown of halogenated hydrocarbons, the body of which acts as a specialized electromagnet capable of immobilizing and retaining very large quantities of non-magnetized ferro- dia- or para-magnetic material-containing nano, micro-, or milli-particles within it's reactor volume despite high-velocity flow of any liquid through said reactor. This is accomplished without any pre-treatment to the nanoparticles, without the use of adhesive of any sort, electroplating, electrolytic action, nano-structured nanocages, membrane or other impregnation, or any other mechanical or chemical means.

Appl. No.:

14/551054

Inventors:

Kenneth W. Cross - Encinitas CA, US

International Classification:

B01J 19/00

US Classification:

422310

Abstract:

A genre of media is presented for use with a reactor vessel and for the purpose of immobilizing small particles, often catalytic in nature. The media can include a number of ferromagnetic active wafers stacked together and separated by non-ferromagnetic separator portions, such that when in the presence of a magnetic field and magnetic-particle-containing fluid, at least some of the gaps between active wafers captures and suspends magnetic particles.
