  • Patent number: 8529645
    Abstract: The present invention provides a system and method for evaluating effects of process parameters on hydrogasification processes. The system includes a hydrogasification reactor, a pressurized feed system, a hopper system, a hydrogen gas source, and a carrier gas source. Pressurized carbonaceous material, such as coal, is fed to the reactor using the carrier gas and reacted with hydrogen to produce natural gas.
    Type: Grant

  • Publication number: 20050280399
    Abstract: An apparatus for managing input power between a passenger bridge and a battery charger includes a power distributor, a current monitor and a controller. The power distributor receives input power and outputs power to the passenger bridge and the battery charger. The current monitor measures current drawn by the passenger bridge and the battery charger to provide a signal to the controller indicative of the power consumption of the passenger bridge and the battery charger. The controller adjusts the output power setting of the battery charger in response to the power consumption of the passenger bridge and the battery charger by reading the output power of the battery charger, comparing the power consumption of the passenger bridge and the battery charger to a predetermined operating threshold to determine whether an overthreshold condition exists, and modulating the battery charger output power setting in response to the overthreshold condition.

  • Patent number: 4743154
    Abstract: A pallet repair and inspection system includes pallet destacking apparatus for automatically dispensing pallets from stack of vertical pallets one at a time and discharging the pallets onto an inspection table. The destacking apparatus includes a vertically reciprocating table onto which the stack of pallets is driven and horizontally reciprocating forks which are operated to suspend all but the lowermost pallet as the table is successively lowered and raised between a pallet discharge height and a pallet pick-up height, to discharge the pallets into the inspection table one at a time. The top of the inspection table is foldable to define a cradle for one end of the pallet, orienting the pallet generally vertically, allowing inspection of its top and bottom surfaces.
