Abstract: Abstract Hydrocarbon Fuel Reforming In a Fog Cooled Fuel Cell Power Plant Assembly The power section of a phosphoric acid fuel cell power plant is cooled by injection of water droplets or fog into the anode gas stream exhaust, wherein the water droplets are vaporized.  The anode exhaust with the water vapor therein is then split with a portion thereof being directed to the burner in the catalytic reformer to be consumed by the reformer burner.  The remainder of the anode exhaust is routed to the reformer inlet where it provides the water necessary for the reforming reaction.  The fog is produced by condensation of water out of the exhaust from a turbocompressor which compresses the air supply for the cathode side of the power section.

Abstract: A hydraulic door opening or closing device comprises a hydraulic fluid pump motor (7) having two ports connected to each end of integral dual manifold (8, 9) and operating cylinder apparatus (10) by way of two branch fluid lines (11, 12). One branch line is fluidly connected to a particular end of the operating cylinder by way of a directional flow valve (17, 18). The other branch line to the same end of the cylinder is fluidly connected to the cylinder by way of an associated manifold (8, 9). Fluid communication with the cylinder through the manifold (8, 9) is accomplished by providing a plurality of valved openings (21-30) linearly disposed along the end of the cylinder between the manifold (8, 9) and the cylinder (10). As a piston (14) of the operating cylinder (10) passes these openings, a door coupled to the piston (14) is automatically slowed as fluid on the drive side of the piston is returned through the openings to the hydraulic fluid pump (7). A simplified control circuit coupled to the device provides three modes of operation, an opening mode, a closing mode and a reversing mode from door opening to door closing.
