Abstract: A method and algorithm are provided to operate a gas turbine at baseload in an emission compliant capable mode to avoid combustion dynamics while operating with cold fuel and hot fuel combustion hardware. The method includes performing a gas turbine operational sequence such as a startup to an emission compliant capable mode. A gas fuel temperature is measured. The gas turbine is operated in the emissions compliant capable mode according to a designated fuel split for avoiding combustion dynamics when a temperature for a gas fuel is below a designated value. A determination is made whether a modified wobbe index for the gas fuel is below an emissions compliant value. An alarm is activated if the modified wobbe index is below the emissions compliant value to notify the operator of a potential emissions shift.

Abstract: Disclosed are implantable tissues including one or more enzyme inhibitors bound in the tissues, bioprostheses including the tissue, and methods for incorporating enzyme inhibitors in implantable tissues. Disclosed tissue can exhibit increased resistance to degradation, and specifically, degradation due to enzyme activity following implantation.

A method for cooling a face of a nozzle having a nozzle body that defines a cavity includes flowing a fuel through the cavity and inserting a plenum through the nozzle body into the cavity. The method further includes flowing a fluid through the plenum so that the fluid impinges on the face of the nozzle to remove heat.

A method for operating a combined cycle power plant includes compressing a working fluid in a compressor and cooling the compressed working fluid with a regenerative heat exchanger so as to create a cooled compressed working fluid. The method further includes transferring heat from the regenerative heat exchanger to a steam generator.

Abstract: A balloon catheter device, for example an enteral feeding catheter, includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. A base is located at the proximal end of the catheter and has an opening to the catheter lumen. An inflatable balloon is located at a distal end of the catheter and is inflated through an inflation valve located on the base. An internal cavity is defined in the base and is in fluid communication with the inflatable balloon such that fluid used to inflate the balloon to an operational fill volume fills the internal cavity as well. A translucent window is disposed over the internal cavity such that an interior volume of the cavity is externally viewable. Introduction of a colored fluid through the inflation valve to inflate the balloon results in the colored fluid also being present in the internal cavity, thereby providing an externally visual indication of the inflation state of the balloon.

Abstract: A solid electrolytic capacitor has a capacitor body formed from a pressed anode, a dielectric layer and a solid electrolyte layer. An anode lead extends from anode pellet and is electrically connected to an anode termination. The outer surface of the capacitor body forms a cathode that is electrically connected to a cathode termination. Base anode and cathode termination portions are coplanar and connected with a recessed leadframe channel. A capacitor element is attached to the anode and cathode termination portions and encapsulated. The recessed leadframe channel is removed to isolate the anode and cathode terminations on a single mounting surface, leaving a surface groove formed between the anode and cathode terminations.

Abstract: A chemically-activated conformable thermal device that generates heat upon activation is provided. The thermal device typically contains an oxidizable metal that is capable of undergoing an exothermic reaction in the presence of moisture and air to generate heat. Although such metals, as well as other components of the composition (e.g., carbon), are relatively inflexible and stiff, the present inventors have nevertheless discovered that one or more conformable segments may be employed to impart flexibility and conformability to the thermal device. The conformable segments are malleable so that they yield under shear stress and acquire the shape of a surface (e.g., body part) without rupturing. The conformable segments are likewise stiff or hard enough to substantially retain the desired shape during use.

Abstract: A system and process for producing tissue webs is disclosed. The tissue webs are formed from an aqueous suspension of fibers and dried using a through-air dryer. During formation of the web, the web is transferred from a transfer fabric to a throughdrying fabric and then conveyed around a drying cylinder of a through-air dryer. In accordance with the present invention, a pressurized roll emits a gaseous stream through a pressurized zone that pushes and transfers a wet web from a transfer fabric to the throughdrying fabric. The amount of pressure used during the transfer can vary depending upon the particular application and may be used to control the bulk of the web. By using a pressurized transfer roll, the amount the throughdrying fabric is wrapped around the drying cylinder of the through-air dryer can be maximized for increasing the efficiency of the system and the process.

Abstract: A signal filtering technique is designed to remove the effects of a periodic, low-frequency noise signal from a signal of interest. A signal waveform is sampled at different points of a number of consecutive periodic noise signal cycles and the collected samples are averaged to produce a corrected signal. The number of consecutive cycles in which samples are taken and averaged is inversely related to the signal amplitude such that as the signal level decreases, the number of cycles examined increases. The technique is particularly applicable to periodic signals associated with the output of Hall effect sensors in an electrical metrology environment. Improved RMS calculations are obtained for filtering low-frequency random noise from Hall sensors by averaging samples at different points of a signal cycle to create a composite desired signal cycle to facilitate other signal calculations.
