Information display system

Abstract: A functional approach to an information display system that enables a fast and easy understanding of the status of a complex process. The display screen is organized by process goals. Each process goal is then tied to a number of process objectives which directly relate individually to the goals. The objectives are in turn tied to the process functions which must be substantially maintained in order to achieve the respective objectives. A display of control functions related to each process function is mapped onto the regional displays. The individual display elements use a combination of coded background color, border color and other indicia of information, e.g., mimics, meters, etc. to present a significant amount of information about the status of the process and its components in a manner that is readily absorbed and easily understood.

Modular resonators for suppressing combustion instabilities in gas turbine power plants

Abstract: A resonator module for a combustion turbine power plant, where the combustion turbine power plant defines a flow path. The resonator module includes a first member, an a second member. The first member has a size substantially smaller than the diameter of said flow path and a plurality of openings therethrough. The openings are in fluid communication with the flow path. The second member has a size generally equal to said first member. The second member is in a generally spaced relation to the first member and encloses a volume of gas between the first and second members.

Water and Forced-Air Cooling of Vacuum Tubes Nonelectronic Problems in Electronic Tubes

Abstract: General laws of heat transfer from a hot wall to a moving fluid are applied to water and forced-air cooling of vacuum tubes. The calculated data are compared with experimental results. The practical importance of various factors constituting the mechanism of heat transfer is analyzed; the role of the internal structure of the tube on the dissipation limits is discussed generally. Rules for designing finned air coolers are outlined, and the "optimum" design is discussed. Numerical examples are given. Some limiting factors in cooler design are analyzed.

Dendritic solidification in binary alloys

Abstract: Alloys generally solidify dendritically, and associated with that is the microsegregation of impurities. Pure metals also solidify in dendritic form as 'thermal' dendrites, which actually segregate the system's enthalpy. In this investigation, small additions of solute to succinonitrile have been studied and dendritic growth observed in a supercooled melt. This free dendritic growth-mode is similar to that experienced by equiaxed dendrites found in alloy castings. Observations of these free dendrites include measurement of velocity and tip radius of the dendrites at different supercoolings and solute concentrations.

The adverse effects of excitation system VAr and power factor controllers

Abstract: The trend toward automation of today's power stations has prompted an increased demand for excitation systems having voltage regulators with the ability to automatically regulate generator reactive power (VAr) output or power factor (PF). While not really a new type of control, automatic VAr and PF controllers are appearing in the specifications of more and more power plants and generator voltage regulators. This paper provides a functional description of voltage, VAr, and PF controllers and regulators, along with an example demonstrating the superior steady-state voltage support performance on a transmission system by regulating voltage, rather than VArs or PF. The paper concludes that VAr/PF controllers or regulators should generally not be specified or utilized on excitation controls for voltage supporting generator applications.
