A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. The device includes an input receptacle for receiving a stack of bills to be evaluated and a single output receptacle for receiving the bills after they have been evaluated. A transport mechanism transports the bills, one at a time, from the input receptacle to the output receptacle along a transport path. The device further includes a discriminating unit that evaluates the bills. The discriminating unit comprises two detectors positioned along the transport path between the input receptacle and the output receptacle. The detectors are disposed on opposite sides of the transport path so that they are disposed adjacent to opposite sides of the bills. The discriminating unit counts and determines the denomination of the bills. The evaluation device also includes means for flagging a bill when the denomination of the bill is not determined by the discriminating unit.

A system and method for treating wastewater includes a treatment container for receiving and treating wastewater and a mixing / aeration system disposed in the treatment container. Wastewater is pumped under pressure from the treatment container through a solids / liquid separation system, preferably comprising multiple parallel membrane bioreactors, to separate the solids and liquids in the wastewater. Liquid retentate from the solids / liquid separation system is cycled back to the treatment container via the mixing / aeration system. The closed-loop system and method for solids / liquid separation and aeration / mixing provides for reduced equipment requirements and energy usage during operation.

A method and apparatus for inspection of containers including a circular star wheel conveyor having a plurality of intermediate annular inspection pockets and at least one non-inspection position. The method includes the steps of providing an outfeed stripper configured to engage a container disposed in the non-inspection position aligning the outfeed stripper inside the circumference of the star wheel conveyor and aligning the outfeed stripper with the conveyor and with the rotational path of the star wheel. Positioning an outfeed mechanism adjacent to the star wheel conveyor and operating the outfeed mechanism at a desired conveyor speed. Controlling the movement of the star wheel conveyor to align the container with the outfeed stripper and the outfeed mechanism only at the non-inspection position regardless of the number of angular inspection positions.

The invention describes a product and a method for generating electrical power directly from nuclear power. More particularly, the invention describes the use of a liquid semiconductor as a means for efficiently converting nuclear energy, either nuclear fission and / or radiation energy, directly into electrical energy. Direct conversion of nuclear energy to electrical energy is achieved by placing nuclear material in close proximity to a liquid semiconductor. Nuclear energy emitted from the nuclear material, in the form of fission fragments or radiation, enters the liquid semiconductor and creates electron-hole pairs. By using an appropriate electrical circuit an electrical load is applied and electrical energy generated as a result of the creation of the electron-hole pairs.

A rotor system vibration absorber for use with a helicopter of other rotorcraft is disclosed in which spring forces are provided by a plurality of elongated rods arranged in a selected pattern. The rods are coupled at one end to a fixed base that is coupled to a rotor hub, and at the other end to a tuning weight.

A mobile compression and tension bridge and shelter structure having a plurality of individual structural elements that are parallel to each other and perpendicular to the length of the bridge or shelter. The structural elements are flexibly connected to one another on a bottom surface forming an arch caused by the shape of the elements or by placing spacers between the elements with at least one tension device attached to each structural element.

A system for metering fuel to an engine. The system includes a fuel metering valve having a throttled inlet and a throttled outlet. The system also provides regulation of redundant pump supplies of fuel to the engine. The throttling of the inlet to the fuel metering valve is provided by a valve that also functions to selectively couple a second fuel pump to the fuel metering valve.

The method for thermal management of a battery can include vehicle systems to control the thermal input to the battery and a dedicated battery thermal management system. The battery thermal management system includes transferring battery heat to coolant flowing in a circuit, if ambient air temperature is greater than the battery temperature, using an evaporator / chiller to transfer heat from the coolant to a refrigerant, using a condenser to transfer heat from the refrigerant to the coolant, and using a radiator to transfer heat from the coolant to ambient air; and if coolant can be maintained in the reference temperature range without using a heat source or refrigerant, using a radiator to transfer heat from the coolant to the ambient air.

A base station for a mobile communications system, a mobile communications system including the base station and a method of increasing base station capacity. Each base station antenna is coupled to a transmission line that may be connected to a triplexer. The triplexer separates uplink signals from a duplex signal on the transmission line. The uplink and downlink signals are both in two sub-bands that are separated by a third sub-band. The triplexer passes the uplink signal to a duplexer / combiner that forwards the uplink signal to a combiner. The duplexer / combiner and combiner each pass downlink signals in one of the sub-bands to the triplexer, which combines the passes to the duplex signal.
