摘要： A thermal management system for a gas turbine powerplant with an engine oil line and an engine fuel line incorporates a heat transfer control module that includes a reversible heat pump with a heat pump compressor for circulating working fluid in forward and reverse directions through a working fluid line of the heat pump. The heat control module also includes a first heat exchanger having a heat exchange path for the working fluid between the compressor and a heat pump expansion valve and another heat exchange path for the engine oil. A second heat exchanger has a heat exchange path for the working fluid between the compressor and the expansion valve and another heat exchange path for the engine fuel. The heat pump can be operated in forward or reverse directions depending on whether heat is to be transferred from the engine oil or the fuel to the heat pump working fluid. In another embodiment an engine oil reservoir located between the first heat exchanger and the engine collects the oil before it is introduced to the engine and thus acts as a heat capacitor for the system.

摘要： A boat lift uses the boat's own propulsive force to lift the boat out of the water. The boat lift comprises a lift frame mounted to a boat dock for rotation, and in a boat receiving position is rotated so that the boat can propel itself onto a boat cradle on the lift frame. A lower trolley slidably mounted on the frame includes a buoyant body in the water for exerting an upward force on the frame. An upper trolley slidably mounted on the frame is engaged by the boat as it propels itself forward onto the boat cradle. The upper trolley is linked to the lower trolley to cause the lower trolley to slide rearwardly under the boat, thus moving the buoyant body rearwardly and rotating the lift frame into a final docking position in which the boat is lifted out of the water. The upper trolley is locked into position, thus locking the lower trolley in position through the linkage between them, and a boat retainer actuated by the lower trolley engages the rear of the boat to hold it on the boat cradle. The boat is launched by releasing the upper trolley lock, which permits the upper trolley to slide rearwardly, with concomitant forward sliding movement of the lower trolley that releases the boat retainer. The forward movement of the lower trolley permits the frame to rotate and launch the boat from the rear of the frame. When a boat is not mounted on the lift, it rests in the boat receiving position.

摘要： A boat lift includes a lift frame rotatably mounted to a boat dock. A lower trolley with a buoyant body slides on the frame. An upper trolley slides on the frame and is engaged by the boat as it propels itself forward onto the frame when the latter is in a boat receiving position. A linkage connected between the trolleys causes the lower trolley and the buoyant body to slide rearwardly underneath the boat to rotate the lift frame into a final docking position in which the boat is out of the water. The upper trolley is locked into position, thus holding the lower trolley in position through the linkage. The boat is launched by releasing the upper trolley lock, which permits the upper trolley to slide rearwardly, with concomitant forward sliding movement of the lower trolley that permits the frame to rotate and launch the boat from the frame.
