Abstract: A flexible heat exchanger is incorporated into a ridge vent to form an assembly. The heat exchanger operates by collecting thermal energy (heat) from heated air exhausting from the attic space via the ridge vent. Air in the attic space is typically heated by the solar energy falling on the roof. Heat from this air is transferred through the wall of heat exchange tubes integrated into the ridge vent. The flow of heated air around the outside of the tubes is driven by the column of heated air that forms in the attic space, similar to the draft in a chimney. The chimney effect in the attic space circulates the flow of outside air into the soffit vents through the attic space where it is heated and then exhausted out the ridge vent, passing by and around the tubes before it exits.

Abstract: In a preferred embodiment, a grip for a golf putter, including: a center member; and two side members coaxially aligned side-by-side with the center member, such as to define therebetween two grooves each of the two grooves disposed between one of the side members and the center member. A method of using the golf putter grip is also provided.

Abstract: In a preferred embodiment, a quick termination modular connector, including: a housing; a first opening defined through a surface of the housing to accept removably secured therein at least one first wire; at least one spring contact disposed in the housing; a second opening defined through a surface of the housing to accept removably secured therein at least one second wire; and when the at least one first wire is inserted in the first opening and the at least one second wire is inserted in the second opening, the at least one first wire and the at least one second wire will engage the at least one spring contact and the at least one spring contact will thereafter maintain electrical contact therebetween with constant, positive pressure without the use of a mechanical fastener.

Abstract: In a preferred embodiment, an engine, including: a housing having a cylindrical inner surface; a first circular block rotatably disposed within the housing and coaxial therewith, the first circular block having its outer surface circumjacent the inner surface; at least one first cylinder radially defined in the first circular block, the at least one first cylinder having its upper, open end disposed at the outer surface; at least one piston disposed in the at least one first cylinder for reciprocating motion therein; at least two inlet chambers defined in the housing and connected to a source of inlet gas to introduce inlet gas into the at least one first cylinder as the open end passes one of the at least two inlet chambers; at least two outlet chambers defined in the housing to permit outlet gas to exit the at least one first cylinder as the open end passes one of the at least two inlet chambers; and means to cause the first circular block to rotate as a result of a power stroke of the at least one piston.

Abstract: In a preferred embodiment, a power module for use in an electrical system of the type having a multiplexer which provides an output signal in response to an input signal, the output signal commanding that electrical power be furnished to a device, the power module including: a housing; a first end of the housing being adapted to be inserted into an electrical outlet; a second end of the housing being adapted for electrical connection to the device, such that, when the power module is turned on, electrical power will be furnished to the device and, when the power module is turned off, electrical power will be removed from the device; and connection means to connect the power module with the multiplexer to receive the output signal from the multiplexer so that the output signal will turn the power module on and/or off. In another aspect of the invention, a power switch similar to the power module is provided. In a further aspect of the invention, a telephone modular connector is provided.
