Air And Gas Mixing Apparatus With Removable Baffle Plates
US Patent:
5662722, Sep 2, 1997
Filed:
Aug 1, 1995
Appl. No.:
8/509829
Inventors:
Samir S. Shiban - Beaverton OR
Assignee:
Innovative Engineering Solutions, Inc. - Beaverton OR
International Classification:
B01D 4508
US Classification:
55413
Abstract:
A housing receives ambient air through an inlet located so as to direct the airflow against blades of a rotor which disperses the airflow. A gas inlet conduit discharges hazardous gas into a chamber of the housing. The dispersed airflow acts on the hazardous gas entering the chamber to disperse and mix with the gas. The mixed air and hazardous gas flow impinges against a wall surface of the housing prior to discharge from the housing via an outlet conduit. A source such as the intake side of a blower induces the flow of air and hazardous gas through the housing and the outlet conduit. The rotor is located near an air inlet of the housing for rotor operation by airflow drawn into the housing. A flow sensor and damper control system are provided. Baffle assemblies are removably installed in the housing and include apertured plates which collect particles deposited by the mixed air and gas flow.
Pyrophoric Gas Neutralization Chamber
US Patent:
5271908, Dec 21, 1993
Filed:
Apr 7, 1992
Appl. No.:
7/864673
Inventors:
Samir S. Shiban - Beaverton OR
Daniel G. Morgan - Tigard OR
Daniel G. Morgan - Tigard OR
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
B01F 302
US Classification:
422228
Abstract:
A pyrophoric gas neutralization chamber is disclosed. The chamber can be used to neutralize a stream of spent process gas from, for example, a chemical vapor deposition process containing, for example, silane. The disclosed chamber is a multi-tiered structure which provides a turbulent flow of air and gas which provides for a controlled neutralization reaction. The chamber operates over a wide range of incoming pyrophoric gas flows to neutralize virtually all of the pyrophoric gas, such that the risk of explosion is eliminated. Finally, the disclosed chamber is inactive in that no fuel source, ignitors, or flame is required. The turbulence in the air/gas flow causes the pyrophoric gas to react with the air without an induced flame.
Method For Reacting Pyrophoric Gas
US Patent:
6084148, Jul 4, 2000
Filed:
Aug 19, 1993
Appl. No.:
8/109166
Inventors:
Samir S. Shiban - Beaverton OR
Daniel G. Morgan - Tigard OR
Daniel G. Morgan - Tigard OR
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
B01D 5334
US Classification:
588202
Abstract:
A method for reacting a pyrophoric gas is disclosed. In the method, a stream of spent process gas from, for example, a chemical vapor deposition process containing silane is mixed with the oxidizing gas flow such as air. The combined flow is sufficiently turbulent to provide for a controlled reaction of the silane. The method may be used for a wide range of pyrophoric gas flow rates, such that the risk of explosion is eliminated. The reaction between silane and oxygen occurs spontaneously. Because the reaction proceeds spontaneously, no ignitor is necessary. Additionally, the method requires no external fuel source and, due to the turbulence proceeds even in conditions were no flame is generated.
Apparatus For Mixing Hazardous Gas With An Airflow
US Patent:
5353829, Oct 11, 1994
Filed:
Jan 10, 1994
Appl. No.:
8/179067
Inventors:
Samir S. Shiban - Beaverton OR
International Classification:
B01F 504
US Classification:
137 88
Abstract:
A housing receives ambient air through an inlet located so as to direct the airflow against blades of a rotor which disperses the airflow. A gas inlet conduit discharges hazardous gas into a chamber of the housing. The dispersed airflow acts on the hazardous gas entering the chamber to disperse and mix with the gas. The mixed air and hazardous gas flow impinges against a wall surface of the housing prior to discharge from the housing via an outlet conduit.

Hazardous Gas Mixing Apparatus With Rake For Dislodging Conduit Deposits
US Patent:
5699826, Dec 23, 1997
Filed:
Sep 3, 1996
Appl. No.:
8/699722
Inventors:
Samir S. Shiban - Beaverton OR
Assignee:
Innovative Engineering Solutions, Inc. - Beaverton OR
International Classification:
B08B 904
US Classification:
137244
Abstract:
An apparatus is disclosed for mixing ambient air and a hazardous gas with the gas being admitted to the apparatus via an inlet conduit. A rake disposed for travel within said conduit periodically dislodges deposits from the conduit interior with rake travel being along conduit affixed guides. Openings defined by the rake permit a gas flow at all times. Projections on a conduit end wall dislodge deposits from disc edges defining openings. A rake actuator is in communication with a solenoid valve in circuit with a timer and controller for automatic operation of the actuator.
