US Patent:

51376814, Aug 11, 1992

Filed:

May 23, 1990

Appl. No.:

7/527761

Inventors:

Michael Dougherty - Drexel Hill PA

International Classification:

G21C 732

US Classification:

376211

Abstract:

An electrical generating system in which exhaust steam from the turbine is recycled through the turbine to reduce feedwater requirements and condenser complexity. The turbine is an axial flow dual shaft compressor/turbine unit in which a coaxial shaft couples the turbine section to the compressor section. A portion of the energy extracted from the steam is used to power the generator and the remainer is used to power the compressor. The turbine exhaust steam is directed through compressor section and the compressed steam is then mixed with turbine inlet steam by a steam jet ejector. The compressor may be powered from either one or both shafts from the turbine.

E04D 5/06

Abstract:

This invention, in embodiments, relates to a roll comprising a roofing material. The roofing material includes a substrate having a first side and a second side, and a film layer attached to at least one of the first side or the second side of the substrate, the film layer comprising a polymer and having a thickness of 0.5 mils to 100 mils. A single layer of the roofing material achieves a Class A rating for steep slope roofing systems when tested according to UL 790 and/or ASTM E-108 Standard Test Methods for Fire Tests of Roof Coverings. This invention, in embodiments, further relates to a roofing material and a steep slope roofing system.

Abstract:

Disclosed herein is a bioreactor system that allows active perfusive flow through a porous support medium enabling 3D growth of biological samples. In some embodiments, the system comprises a sample well filled with a three-dimensional (3D) cell growth medium. The system can further comprise a liquid medium reservoir fluidly connected to the sample well by a first filter material. The system can further comprises a medium collection chamber fluidly connected to the sample well by a second filter material. In some embodiments, application of negative gage pressure to the medium collection chamber or positive pressure to the liquid medium reservoir draws fluid from the liquid medium reservoir, through the first filter material, into the sample well where it permeates the three-dimensional cell growth medium, through the second filter material, and finally into the medium collection chamber.
