Abstract: ENGINE OIL PRESSURE MONITOR                   Abstract of the Disclosure An engine oil pressure monitor includes an engine oil pressure sensor and an engine speed sensor.  A plurality of pressure alarm values are generated to correspond to designated distinct ranges of engine speed.  One of the alarm values is selected according to which engine speed range contains the sensed engine speed.  An alarm signal is generated when the sensed pressure falls below the alarm value.  The alarm is disabled when the engine speed falls below a minimum non-zero engine speed and is disabled unless the pressure failure condition persists for at least a predetermined time period.

Abstract: DEHYDRATION OF LIGNITE OR THE LIKE    ABSTRACT          A method and apparatus are provided for the dehydration of low rank coal, such as lignite, by steam drying or hot water drying.  The coal is formed into particles having a size of less than about 4 inches, and is subjected to pre-steaming.          The particles are then entrained in liquid and fed to a high pressure feeder at which they are transferred to a high pressure circulation loop, and are fed to a liquid/particles separator at the top of a vertical vessel.  The particles at the top of the vessel are contacted by saturated steam, or with hot water (e.g. 250-260°C) flowing countercurrently thereto.  The particles are ultimately subjected to a countercurrent wash at the bottom of a vessel.  A slurry of liquid and particles discharged from the bottom of the vessel after washing has the pressure thereof gradually reduced in a second high pressure feeder, and is transferred to a low pressure loop.          The liquid and particles in the low pressure loop are separated, and then the particles are subjected to evaporative cooling to produce dehydrated, dry, low rank coal.

Abstract: ABSTRACT           INTEGRAL GAS SEAL FOR FUEL CELL GAS   DISTRIBUTION ASSEMBLIES & METHOD OF FABRICATION    A porous gas distribution plate assembly for a fuel cell,  such  as  a  bipolar  assembly,  includes an  inner impervious region wherein the bipolar assembly has good surface  porosity  but  no  through-plane  porosity  and wherein electrical conductivity  through the  impervious region is maintained.  A hot-pressing process for forming the bipolar assembly includes placing a layer of thermo-plastic  sealant  material  between  a  pair  of  porous, electrically conductive plates, applying pressure to the assembly  at  elevated  temperature,  and  allowing  the assembly to cool before removing the pressure whereby the layer of sealant material is melted and diffused into the porous plates to form an impervious bond along a common interface between the plates holding the porous plates together.  The distribution of sealant within the pores along the surface of  the plates provides an effective barrier at their common interface against through-plane transmission of gas.
