Abstract: A method and control system can implement a transient exhaust pressure protection logic to avoid a turbine exhaust vacuum trip due to a short duration turbine exhaust pressure transient that may be caused by a large reduction in turbine flow coupled with a transient increase in exhaust pressure, which specifically occurs during full load rejections. When full load rejection conditions are sensed by power load unbalance and confirmed by secondary indications, normal alarm settings and trip settings for turbine exhaust pressure are blocked for a delay period while transient operating limits are in place.

Abstract: To provide auxiliary steam, a low pressure valve is opened in a combined cycle system to divert low pressure steam from the heat recovery steam generator to a header for supplying steam to a second combined cycle's steam turbine seals, sparging devices and cooling steam for the steam turbine if the steam turbine and gas turbine lie on a common shaft with the generator. Cooling steam is supplied the gas turbine in the combined cycle system from the high pressure steam turbine. Spent gas turbine cooling steam may augment the low pressure steam supplied to the header by opening a high pressure valve whereby high and low pressure steam flows are combined. An attemperator is used to reduce the temperature of the combined steam in response to auxiliary steam flows above a predetermined flow and a steam header temperature above a predetermined temperature.

Abstract: Topical medicinal pressurized aerosol compositions and method of preparation, method of use and article of manufacture thereof especially wherein the topical medicament is mafenide or a pharmaceutically acceptable acid addition salt thereof, most especially mafenide acetate, and especially for treatment of burns are disclosed.

Abstract: Extrudable elastic oral pharmaceutical gel compositions, especially containing aetaminophen as the therapeutically active agent, and manually operable metered dose dispensers containing them and method of making and method of use thereof are disclosed.

Abstract: The invention comprises a syringe for extrusion of a semi-plastic mass, or a mass having a paste-like consistency. In a preferred embodiment, the syringe is so-designed to permit mixing of two components of a plasticizable mixture within the syringe barrel. The bore of the syringe barrel is flared to facilitate extrusion of the plastic mass therefrom. The parts of the syringe ready for use are packaged in a one-piece tray which serves not only for shipping and storing of the syringe, which may be preloaded with one of the components of the plasticizable mixture, together with the associated syringe parts, but which also serves, when opened for use, as a convenient tray for handling the syringe while mixing the two components of the plasticizable mixture prior to extrusion.

Abstract: Antiplaque dentifrices containing as the antiplaque ingredient the saccharin salt of an amino or quaternary ammonium antimicrobial agent, particularly chlorhexidine saccharin salt or octenidine saccharin salt, and the method of inhibiting, reducing and preventing dental plaque therewith are disclosed.
