摘要： The invention concerns a device to generate mechanical work with a steam engine that works with a closed circuit and that has a feed water tank, a feed pump, an evaporator to generate steam, the steam engine, and a condenser. The invention is based on the problem of keeping a device of the initially cited kind free of damage from freezing water when the device is not operating and the environmental temperatures are low. To this end, an inert gas in the feed water tank (10) is used to expel the feed water from the other part (36) of the circuit to the feed water tank (10). This is done by switching a valve arrangement. The feed water tank (10) is designed so that it will not be damaged, for example by exploding from freezing water inside. The advantages of the closed circuit are retained. To restart the device, the system is reheated, and the valve arrangement only has to be switched back to the position suitable for normal operation.

摘要： The present invention permits determination of steady-state off-design performance characteristics of a vehicle, such as a torpedo, powered by a closed cycle thermal propulsion system. The method may be utilized to determine propellant consumption for a torpedo resulting from various off-design kinematic maneuvers. Total run time may be calculated in response to a plurality of torpedo speed changes and/or torpedo configurations of variable torpedo length or torpedo diameter. The present invention may be utilized to define weapon design options for existing or future underwater weapons with mission requirements different from those for which the weapons were originally designed.

摘要： The present invention relates to a flexible inlet tube for a high and intermediate pressure steam turbine. A reheat steam inlet tube is constructed integrally with a casing. The inlet tube has a double tube portion to form an annular groove. The lower end of the double tube portion has an expanded diameter, and a vertical sliding motion can be accomplished between the expanded diameter portion and a flange fixed to a thermal shield, so that thermal elongation is absorbed. Low-temperature steam flows into the annular groove from an in-casing space through a hole, circulates in the annular groove, and flows out to a steam passage in an intermediate pressure turbine section, by which the interior of the annular groove is cooled, so that a temperature rise of the casing can be prevented.

摘要： Uninterruptible power supplies are provided that utilize a material to provide a source of thermal energy that may be converted to electrical energy to produce backup electrical power for a load. In some embodiments, a hot tank assembly is utilized to hold a liquid heated to a predetermined temperature. A closed-loop pipe containing, water for example, is immersed in the heated liquid. Upon the loss of primary power, the water flows into the heat exchanger where it is raised above its boiling temperature. The steam is then passed to a heat engine (e.g., a turbine-based system) that converts the heated steam to mechanical energy by causing the heat engine rotor to rotate. A generator is physically coupled to the heat engine so that the rotation of the heat engine rotor drives the generator. The generator produces AC power which is converted to DC and again back to AC before being provided to the load. In other embodiments, a solid mass, such as a block of iron, is heated to a predetermined temperature. The heat from the solid material is then converted to electrical energy for the load.
