Abstract: A multiple layer insulation cover for preventing heat loss in, for example, a greenhouse, is disclosed. The cover is comprised of spaced layers of thin foil covered fabric separated from each other by air spaces. The spacing is accomplished by the inflation of spaced air bladders which are integrally formed in the cover and to which the layers of the cover are secured.

The sizes of the material layers are selected to compensate for sagging across the width of the cover so that the desired spacing is uniformly maintained when the cover has been deployed. The bladders are deflated as the cover is stored thereby expediting the storage process and reducing the amount of storage space required.

Abstract: A method is disclosed for improving the operational efficiency of a steam turbine power plant by governing the adjustment of the throttle steam pressure of a steam turbine at a desired power plant output demand value. In the preferred embodiment, the impulse chamber pressure of a high pressure section of the steam turbine is measured as a representation of the steam flow through the steam turbine. At times during the operation of the plant at the desired output demand value, the throttle pressure is perturbed. The impulse chamber pressure is measured before and after the perturbations of the throttle pressure. Because changing thermodynamic conditions may occur possibly as a result of the perturbations and provide an erroneous representation of the steam flow through the turbine, the impulse chamber pressure measurements are compensated for determined measurable thermodynamic conditions in the steam turbine.

A maximum compressor run time interval between defrost cycles is provided for when no door openings occur, as during vacation periods.
