US Patent:

6409807, Jun 25, 2002

Filed:

May 23, 2000

Appl. No.:

09/576050

Inventors:

Charles Bradley Hager - Davenport IA
Kevin Michael Dailey - Rock Island IL

Assignee:

Litton Systems, Inc. - Los Angeles CA

International Classification:

B01D 5304

US Classification:

96111, 96114, 96130

Abstract:

The present invention relates to detecting the state of a slide block positioned in a linear valve and using the position of the slide block to predict the health of a linear valve and provide information to a controller/monitor. An operator is provided with information before failure occurrence to allow preventative maintenance of the linear valve. The linear valve is constructed with two canister ports and a vent port. The slide block can be constructed to block the two canister ports and vent port simultaneously. The system can control the position of the block, when provided with position information, hence, using the slide block as a shutoff valve. The typical slide valve can be used as an integral slide shutoff valve, reducing system complexity and reducing system weight, which is critical to airborne applications.

International Classification:

B01D 53047

US Classification:

95 8, 95 13, 95 96, 96111, 96116, 96130, 96399

Abstract:

A controller system for a molecular sieve device controls a product gas generated by n molecular sieve beds for separating a gas from an input gas supply. A valve assembly with n states has an input receiving the input gas and n outlets. Each valve state in a first position creates an open passageway from the input of the slide valve to an outlet. Transitioning a valve from the first to a second position creates a variable amount of restriction in the flow of gas between the input and a selected outlet.

Assignee:

Carleton Life Support Systems, Inc. - Orchard Park NY

International Classification:

F16K 11/06

US Classification:

137309, 96130, 13762543

Abstract:

A slide type valve (V) for regulating a gas generating system () that has at least a first and a second gas concentrating bed unit () includes an outer body () with a slide face () having at least three open ports () communicating with an interior cavity () formed in the outer body (). A vent port () and at least two bed ports () are adapted to communicate an air flow with a gas concentrating bed unit (). The vent port () is formed between two bed ports. A slide block () having an essentially flat face () slides along the slide face interior surface () of the outer body () and has an interior cavity () and a first and a second opening (). The slide block slide face () has a closing portion () positioned between the first and second openings (). A controller (C) moves the slide block () between a first state (S) and a second state (S) for desired air flow.

International Classification:

B01D 53047

US Classification:

95 11

Abstract:

A method of controlling an oxygen concentrator having a first sieve bed operated over successive control periods according to a duty cycle for alternately pressurizing and flushing the first sieve bed and a second sieve bed operated over the successive control periods according to a reciprocal of the duty cycle is disclosed. The duty cycle and the reciprocal duty cycle are adjusted during every second one of the successive control periods to change the pressurizing relative to the flushing of the first sieve bed and to change the flushing relative to the pressurizing of the second sieve bed, for reducing concentration of oxygen produced. The duty cycle and the reciprocal duty cycle are adjusted during remaining control periods to change the flushing relative to the pressurizing of the first sieve bed and to change the pressurizing relative to the flushing of the second sieve bed, such that water vapor is purged from the first and second sieve beds after pressurizing thereof. A pressure-swing adsorption (PSA) subsystem performance check is disclosed. This test is performed as part of a maintenance BIT (Built-In-Test) function.
