Abstract: An automated system is provided for aligning a vehicle tow ball with a tow cup of a trailer. The vehicle has a controller connected to at least some of the vehicle steering, transmission and braking systems to enable the controller automatically to steer and/or move and/or brake the vehicle. Sensors at the rear of the vehicle detect the presence of an object within a region behind the vehicle. The sensors are connected to the controller to utilize the data from the sensors to identify the tow cup of a trailer located within the region behind the vehicle, and to control the reversing of the vehicle in order to bring the tow ball into alignment beneath the identified tow cup so as to facilitate coupling of the tow cup onto the tow ball.

Abstract: Disclosed is an air-assisted fuel injection system, comprising a cylindrical bore; a plunger and a barrel within the cylindrical bore, the plunger having a flat surface; and a securing means abutting against the flat surface to keep the plunger from rotating within the cylindrical bore.

Abstract: Disclosed is a diesel engine comprising a cylinder head; a combustion chamber within the cylinder head, the combustion chamber being in the shape of a bowl; and a piston having a piston crown, the piston crown having a dome-shape for protruding within the cylinder head during a combustion operation near or at top dead center. The engine is preferably a two stroke crankcase compression engine. Use of a combustion chamber in the shape of a shallow bowl along with other parameter selection decreases the rates of combustion pressure rise while providing reasonable power output.

Abstract: A baseboard radiator having notched fins. The notches are retained by a flange on a back plate mounted to a wall. The fins are further retained by a flange in the upper portion of the back plate.

Abstract: An apparatus for testing lubricity of a fuel includes a testing chamber for holding a sample of the fuel to be tested; an inlet for admitting the sample to the testing chamber; and an assembly for sealing the testing chamber to prevent moisture transfer during admission and testing of the fuel. In this way, more consistent results are obtained.

Abstract: An apparatus for internal climate control. The apparatus comprises an inlet and outlet for air, a tangential fan that rotates about a vertically oriented axis, a fan coil assembly through which air is circulated by the tangential fan from the inlet to the outlet, a barrier to prevent recirculation of the air within the apparatus after it is circulated over the fan coil assembly, and a joint to provide fluidic communication with a source of recirculating fluid. The fan coil assembly is connected in series to the source of recirculating fluid and provides thermal communication between the recirculating fluid and the circulating air.

Abstract: Air temperature is adjusted by employing a tangential fan having a vertically-oriented axis to direct air over a coil assembly, directing a fluid through the coil assembly, and adjusting the temperature of the fluid to cool or heat the air, wherein the coil assembly provides thermal communication between the air and the fluid.

Abstract: A modular climate control unit for use with circulating coolant. The unit includes two tangential fans oriented vertically and disposed one over the other. The fans direct air over an aluminum fin/copper fan coil assembly which is in thermal communication with both water coming from and returning to a central water heating or cooling system. The unit is compact and fits between two studs between a wall; air is directed into and out of it through parallel vertical louvers. The orientation of the tangential fans increases unit efficiency while reducing noise levels. The unit is easily accessed for maintenance within the wall and can direct air to an adjacent room.
