Filed:

May 29, 2008

Appl. No.:

12/156181

Inventors:

Louis S. Schwartz - Bethlehem PA, US
David Waage - Bethlehem PA, US

International Classification:

F04D 29/56

US Classification:

415160

Abstract:

The invention relates to increasing the fluid capacity and the fluid discharge pressure of a rotary sliding vane fluid compressor without significantly increasing the fluid discharge temperature. According to the invention supplemental air under pressure is added to a compressor's rotating pocket to increase the fluid capacity and fluid pressure in the pocket.

Appl. No.:

12/316717

Inventors:

Louis S. Schwartz - Northampton PA, US
David Waage - Cobleskill NY, US

International Classification:

F01C 1/00

US Classification:

418266

Abstract:

Disclosed is a blade for a rotary blade compressor. The blade has at least two section pieces, with any two adjacent section pieces being radially aligned with each other at a junction, wherein further there is a force applying means at said junction forcing the adjacent blade section pieces apart from each other in an axial direction. The edges of said blade will thereby be positioned to form a seal against the head plates of the compressor.

David J. WAAGE - Cobleskill NY, US

Assignee:

THE RESEARCH FOUNDATION OF STATE UNIVERSITY OF NEW YORK - Albany NY

International Classification:

C10J 3/00
C01B 3/02
C10J 3/84

Abstract:

A gasifier system includes a reactor for receiving a wet feedstock which has a base and a container rotatably connected to the base such that a rotation of the container causes a mixing of the feedstock in an interior of the reactor. The interior is bounded by the base and the container. A space between the base and the container allows an entry of oxygen into the interior. The space has a dimension such that the feedstock is fully oxidized in a combustion area adjacent the base and such that the feedstock avoids combustion in a remainder of the interior. The reactor has a longitudinal axis inclined at an inclination angle relative to a horizontal line to promote the mixing of the feedstock in the interior.
