Title: Reactant distribution for multi-stack fuell cell power plants
Inventor: KATZ MURRAY
IPC: H01M8/04
Filed: 1987-06-02
Granted: 1991-10-15
Abstract: Abstract of the Disclosure Reactant Distribution For Multi-Stack Fuel Cell Power Plants The fuel cell stacks in a multi-stack power plant are provided with hydrogen-enriched fuel in serial fashion with the fuel outlet (110; 112; 206; 208) of one or more stacks forming the fuel inlet for a subsequent stack in the series.  The fuel can be initially fed into the series via two or more stacks in parallel with the outlets of the parallel stacks being combined and fed serially into the subsequent stacks.  Alternatively, the fuel can be fed through stacks which are arranged in a simple series, one stack after another.  Fueling the stacks in either aforesaid manner ensures that each cell in the stack will receive an adequate amount of fuel for proper functioning and allows for significant relaxing of cell manufacturing tolerances and resulting economics.

Title: Self-aligned and leveled insulated, drystack block structures and means and methods therefor
Inventor: JOHNSON STANLEY D
IPC: E04C1/40
Filed: 1987-08-18
Granted: 1992-03-03
Abstract: ABSTRACT OF THE DISCLOSURE    Means and methods for constructing drystacked self-aligning self-leveling walls and like structures.  A novel construction block has interior, tapered wall cells bounded by transverse webs having an extended V-shaped draft defined therein.  The tapering of the walls provides precisely maintained interior geometry.  Insertable cores of precise dimension and having V-shaped ear members adapted to fit intimately within such V-shaped draft or groove and to cooperatively coact with like cores in adjacent blocks in a running course to establish a fixed spatial relationship between the top surface of the core and the bottom surace of the block to permit the erection of a self-aligned and self-leveling standing wall from drystacked block.  The intimate contact of the insertable cores permit the formation of open-gapped interlocks between blocks and running courses, which open-gapped interlocks are converted to closed-gapped interlocks when a wall erected of such running courses is coated with a surface bonding cement.  A method of creating such a structure is described.

Granted: 1993-11-09
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for determining the interface between two materials having different dielectric properties, especially in determining the thickness of a hydrocarbon layer on ground water, is disclosed.  The apparatus consists of an air-filled, cased surveillance well in which a logging tool is raised and lowered.  The logging tool contains an electromagnetic receiving antenna and two transmitting antennas located above and below the receiving antenna.  A first wave and a second wave are transmitted from the transmitting antennas.  The first and second waves are offset 180° to produce "sum" and "delta" signals.  Alternatively, a single wave can be transmitted from a central transmitting antenna to receiving antennas located above and below the transmitting antenna.  The received signals are then phase shifted 180° to produce sum and delta signals.  As the tool is raised and lowered in the well bore, changes in the sum and delta signals will be observed when an interface is passed.  A logging tool for use in petroleum production and exploration wells is also disclosed.

Abstract: ABSTRACT OF DISCLOSURE     A recording apparatus of toner image transfer type, having an improved cleaning device for removing residual con-taminants on the surface of a notating recording drum after toner image transfer.  The cleaning unit includes a blade of counter type engaging with downwardly moving surface of the drum, a rota-table cleaning brush disposed immediately upstream from the blade, and a housing structure shielding the blade and the rotatable fur brush.  The housing is evacuated by an air pump, and external air is introduced from an opening of the housing, where the fur brush and the blade engage with the surface of the drum.  Thereby, the contaminants removed by the blade and the fur brush from the sur-face of the drum is efficiently discharged by the aid of air flow having velocity enhanced by the above-described pneumatic struc-ture.  The air velocity is further enhanced by forming an air passage passing through the fur brush.

Title: Logic performance verification and transition fault detection
Inventor: CORR JAMES L
IPC: G06F11/22
Filed: 1989-09-27
Granted: 1992-11-24
Abstract: ABSTRACT   In scan testing of logic parts, this invention provides an inexpensive transition fault test by changing the sequence of application of the A/C and B clocks.  In each machine test cycle the B clock is triggered first,  and the A/C clock is triggered second.  The periodicity of the clocks is not changed for a particular cycle,  because in one cycle the B-to-A/C clocking that naturally occurs provides a minimum test window TP for performance and transition fault testing.   Thus, less sophisticated  scan  test  equipment  can  now  provide  both transition fault and stuck fault testing, without an increase in complexity or expense.

Abstract: Wood and wood based materials are bonded with curable amino-formaldehyde resins, preferably urea-formaldehyde resin, in the presence of a ketone-formaldehyde resin. The presence of the ketone-formaldehyde resin gives an increased penetration of the adhesive and a wetting effect. The ketone-formaldehyde resin can be mixed into an adhesive-curing agent composition, into the adhesive or the curing agent. Acetone-formaldehyde resin is the preferred ketone-formaldehyde resin. Products bonded according to the method have an improved resulting strength and the method is preferably employed in high-frequency bonding and for bonding oxidized wood materials.

Abstract: A submarine telecommunications cable includes a plurality of optical fibres in the bore of an orientated plastics strength member. The cable may have an average density of 0.9 to 4.0 and preferably a neutral buoyancy whereby most of the weight of the cable is carried by the sea. This reduces tension in the cable during laying. The bore of a submarine cable is filled with a solid elastomeric embedding medium which occupies the space between the fibres. This gives a void-free structure which assumes ambient pressure. The strength member may be made from orientated polyethylene. The cable is preferably buried in the sea bed during use.

Inventor: WILLIAM SINGLETON ROBERT
IPC: D02G1/00

Granted: 1968-11-11
Abstract: Filamentary material made from an oxymethylene polymer is subjected to a temperature between 45 and 5 DEG C. below the crystalline melting-point of the polymer for a time sufficient to increase the crystallite size of the polymer while maintaining the material under sufficient tension, if necessary, to prevent surface fusion thereof. The material may be filaments, yarns or knitted or woven fabrics of oxymethylene polymer, or copolymer comprising oxymethylene and oxyethylene groups.  The process, while imparting strength and creep resistance to filaments (Division B4-B5) may be used to set yarn or fabric in a predetermined shape.  Yarn may be bulked, voluminised or textured by being held in a crimped, curled or looped configuration, as by knitting, twisting, or use of meshed gears or stuffing box, while heat is applied.  An increase on crystallite size of at least 15% may be achieved by heating the material for e.g. 0.5-15 minutes at 150-160 DEG C.  Heating may be effected by e.g. steam or air.  In Example 1, a yarn melt-spun from a copolymer of trioxane and ethylene oxide is, drawn, twisted, heated on the bobbin at constant length for 15 minutes at 160 DEG C. and the twist is then removed by back twisting, resulting in a bulked yarn.  In Example 4, ladies stockings, knitted from the same co-polymer are pre-boarded at 115 DEG C. for 1 minute, dyed, and post-boarded at 160 DEG C. for 5 minutes.
