Abstract: Methods for producing glass articles from glass melts are provided that include continuously introducing the glass melt into a stirrer vessel, stirring the glass melt in the stirrer vessel by at least one blade stirrer, continuously discharging the glass melt from the stirrer vessel, and shaping the glass melt to obtain the glass article.

In other embodiments, the stirring is sufficient so that the glass melt which is located at a surface in the stirrer vessel is not drawn into the stirrer vessel or is drawn in only insubstantially.

The system is simple to maintain and reduces high installation and maintenance labor costs. The system uses male and female ported fittings and horseshoe pins. Pendant style or deluge style sprays can be used in the system and can be pre-installed prior to delivery and installation of the system.

Abstract: A method is provided for controlling a short-term increase in power in a steam turbine including a fossil-fired steam generator having a flow path through which a flow medium flows. The method involves tapping off the flow medium from the flow path in a pressure stage and injecting it into the flow path on the flow-medium side upstream of a super heater heating surface of the respective pressure stage. A first characteristic value is used as a controlled variable for the amount of injected flow medium. The first characteristic value is characteristic of the deviation between the outlet temperature of a final super heater heating surface of the respective pressure stage on the flow medium side and a predetermined nominal temperature value. The nominal temperature value is reduced and, for the duration of the reduction in the nominal temperature value, the characteristic value is temporarily increased over-proportionately to the deviation.

Abstract: A method is provided for regulating a brief increase in power of a steam turbine that has an upstream fossil-fired once-through steam generator having a plurality of economizer, evaporator and superheater heating surfaces which form a flow path and through which a flow medium flows. The flow of the flow medium through the fossil-fired once-through steam generator is increased in order to achieve the brief increase in power of the steam turbine. The method involves using desired enthalpy value at the outlet of an evaporator heating surface as a control variable for determining a desired value for the flow of the flow medium through the fossil-fired once-through steam generator. The desired enthalpy value is reduced in order to achieve the brief increase in power of the steam turbine.

Abstract: A solar thermal power plant, wherein, in an intermediate superheater in the water-steam circuit, steam is heated to a settable setpoint temperature value at the outlet by a heat carrier medium which has been heated solar-thermally, wherein, for the heating of the steam to a set setpoint temperature value, a mass flow of the heat carrier medium entering the intermediate superheater is controlled as a function of a determined enthalpy difference of the heat carrier medium between the entry and exit thereof into and out of the intermediate superheater and as a function of a determined enthalpy difference of the steam between the exit and entry thereof out of and into the intermediate superheater is provided.

Abstract: A waste heat steam generator for a gas and steam turbine power plant is provided. The generator has economizer, evaporator and superheater heating surfaces which form a flow path and through which a flow medium flows. An overflow line branches off from the flow path and leads to injection valves arranged downstream at a flow side of a superheater heating surface in the flow path. The overflow line permits a brief power increase of a downstream steam turbine without resulting in an excessive loss in efficiency of the steam process. The brief power increase is permitted independently of the type of waste heat steam generator. The branch location of the overflow line is arranged upstream of an evaporator heating surface at the flow medium side and downstream of an economizer heating surface.

Abstract: Embodiments of the present disclosure include systems and methods for image processing for enhancing, e.g., photos, videos, and graphics representations. Particularly, some embodiments perform a histogram-based SMQT decomposition of various attributes in an original image. The SMQT decomposition of these attributes may then be used to create a look-up-table indicating how to modify pixel attributes in the same or a subsequent image so as to enhance the same or subsequent image. The results of the SMQT decomposition for each attribute may be interpolated based, e.g., on user preferences, to achieve a more optimal enhancement.
