Abstract: A hydrogen/oxygen combustion system of direct steam generation of motive flow, with the capacity to regulate and control temperature and pressure conditions, enabling the use of spontaneously generated motive flow in turbine-driven power generating system applications. Steam is generated directly by the combustion reaction between hydrogen and oxygen gas fuel stocks, temperature-regulated by the injection of water into the body of super-heated steam generated by such a reaction. Motive body temperature is controlled by the absorption of heat inherent in the vaporization of water-injectate; regulation of temperature is a function of the ratio of water to feed-stock gas, injected into the motive body. Motive body pressure is regulated by controlling the total flow of gas fuel stocks and water into the combustion chamber of the steam-generating engine. Exhaust steam is compressed and ported to the next engine, or from a final stage to the condenser for recovery.

Abstract: Interfering double images that occur with curved windshields made from laminated glass during night driving in transmission and with head-up displays in reflection can be reduced by a wedge-shaped thermoplastic intermediate film. The wedge-angle profile required for compensation of double images is determined locally as a function of pane shape and installation situation. If the vehicle has a head-up display system, the wedge-angle progression can be determined in the HUD field such that double images are prevented there in reflection. However, outside the HUD field, a wedge-angle progression that compensates double images in transmission is selected. The specifically adapted wedge-angle profile enables better compensation of double images than is possible with a film with a constant wedge angle.
