Abstract: A compact fluorescent cleanup kit is disclosed, which comprises a plurality of member elements. The member elements comprise printed instructions, at least one glove, at least one mask, at least one eye protection member, at least one sealable container, at least one cleanup scoop, at least one single-sided adhesive member, and at least one towelette. The at least one glove, at least one mask, and at least one eye protection member may be donned to protect a user from exposure to metal contaminants that may be released when a compact fluorescent bulb is damaged. The at least one cleanup scoop, at least one single-sided adhesive member, and at least one towelette may be used to collect all debris from a damaged compact fluorescent bulb into the at least one sealable container.

Abstract: A system for generating revenue includes a fee collection station. The fee collection station may include a controller and a fee receiver in communication with the controller for receiving a predetermined fee from a plurality of users. The fee receiver may also receive a predetermined participation fee from the plurality of users that selectively participate in a game. The fee collection station may also comprise an indicator in communication with the controller and adjacent to the fee receiver for indicating to participating users one of a winning indication or a losing indication. The participating users that receive the winning indication may receive a predetermined reward.

Abstract: An energy transfer system includes an energy transfer device, a water inlet pipe and a water outlet pipe. The water inlet pipe may be connected to a water inlet of the transfer device to extract water from a water source. The water outlet pipe may be connected to a water outlet on the energy transfer device to discharge water to the water source. The water inlet pipe may extract water from a predetermined extraction depth, and the water outlet pipe may discharge water into the water source at a predetermined discharge depth.

Abstract: A drawerless point of sale system includes a point of sale terminal and a currency changer device in communication with the point of sale terminal. The currency changer device is adapted to accept cash in bulk for a cash transaction and includes a housing, a coin accepting tray, a coin sorter, a plurality of respective coin bins, and a coin dispenser. The currency changer also includes a bill accepter/dispenser carried by the housing for accepting, sorting and dispensing bills, and a plurality of bill cassettes carried by the housing and in communication with the bill accepter/dispenser for receiving a respective plurality of similar bills from the bill accepter and for dispensing a respective plurality of bills responsive to said point of sale terminal.

Abstract: A heat transfer system includes a water line for carrying water having a first predetermined flow direction and a refrigerant line for carrying a refrigerant and having a second predetermined flow direction opposite the first predetermined flow direction. The heat transfer system includes a refrigerant evaporator, a vapor compressor, a condenser, and an expansion device. Refrigerant is passed through the refrigerant evaporator as a liquid and is warmed to a cooled gas. The refrigerant is heated to a superheated gas in the vapor compressor, and cooled to a warm liquid in the condenser. The refrigerant is cooled to a bi-phase liquid in the expansion device and is then passed to the refrigerant evaporator. Water enters the refrigerant condenser and heat is exchanged between the refrigerant and the water to warm the water to a predetermined water temperature. The water exits the refrigerant condenser and is passed to the water storage member at a predetermined temperature.

Abstract: A lock member that pivotally engages a slide bolt movement member connected to a slide bolt of a locking astragal and that is moveable between locked and unlocked positions includes a user engagement portion and a lock portion. The user engagement portion is substantially flat and adapted to be flush with an outer surface portion of the slide bolt movement member when the lock member is in the locked position and the unlocked position. The lock portion is positioned opposite the user engagement portion, and has an unlocked side that is substantially flat and a locked side having an arcuate shape. The arcuate shaped lock side is positioned adjacent an interior portion of the slide bolt movement member when the lock member is in the locked position, and the substantially flat unlocked side is positioned adjacent the interior portion of the slide bolt movement member when the lock member is in the unlocked position.
