Abstract: A system and method are disclosed to increase the occupancy at a hotel, along with allowing for variable check-in/check-out times. The system allows for the scheduling of the personnel at the hotel based on the variable check-in/check-out times.

Abstract: A mobile system for use in transfer of liquid waste reduces loading and/or unloading times required during transfer to a tank truck or transfer from a tank truck to other equipment such as spreading equipment. The system includes a transfer tank that is raised and lowered to provide improved transfer due to gravity assist. The tank is provided on a structural frame that includes a lifting arrangement for supporting the tank at least six feet above a ground position. Preferably the structural frame is part of a trailer to allow convenient transport. The system has particular application for liquid manure transfer systems.

Abstract: A Hall thruster with a shared magnetic structure including a plurality of plasma accelerators each including an anode and a discharge zone for providing plasma discharge. An electrical circuit having one or more cathodes connected to the plurality of plasma accelerators emits electrons that are attracted to the anode in each of the plasma accelerators. A shared magnetic circuit structure establishes a transverse magnetic field in each of the plurality of plasma accelerators that creates an impedance to the flow of electrons toward the anode in each of the plurality of plasma accelerators and enables ionization of a gas moving through one or more of the plurality of plasma accelerators. The impedance localizes an axial electric field in the plurality of plasma accelerators for accelerating ionized gas through the one or more of the plurality of plasma accelerators to create thrust.

Abstract: An air/atmosphere breathing electrically powered Hall effect thruster including a thruster duct having an inlet, an exit, and a discharge zone between the inlet and the exit for receiving air from the inlet into the discharge zone, an electrical circuit having a cathode for emitting electrons and an anode in the discharge zone for attracting the electrons from the cathode through the exit, and a magnetic circuit for establishing a magnetic field in the discharge zone radially across the duct between the anode and exit which creates an impedance to the flow of electrons toward the anode and enables ionization of the air/atmosphere moving through the discharge zone and which creates an axial electric field in the duct for accelerating ionized air/atmosphere through the exit to create thrust.

Abstract: A water filtration system for both fresh and salt water aquariums. The filter system housing is situated above the aquarium and consequently the aquarium water level thereby allowing gravity and not an integral system pump to return water to the aquarium after undergoing the filtration process. The water flow return rate to the aquarium is always matched exactly to the rate at which water is pumped into the filter system housing by a separate pump which is not a part of this invention. As a direct result of this, complicated valving and synchronization of pumps is not required. Gravity moves the water after intake over a distribution plate assembly and drop it over the entire surface of the biological filter material without the need for moving parts which may fail or wear out during continuous operation. Both mechanical and biological filtration occurs before the water is returned by gravity to the aquarium.
