Solid carboniferous fuels contain varying quantities of moisture, mercury, chlorine, nitrogen, sulfur, heavy metals and other materials that attain vapor pressure at elevated temperatures. The cost effective removal of these degrading and sometimes hazardous materials is important to the further use of the fuel for combustion as a solid, liquid, or gas. The solid fuel is cut, shredded, ground or sieved to appropriate size, and heated in a chamber that can exclude oxygen and air thus preventing ignition. The unwanted materials are driven in the gaseous state and extracted for disposal. The solid fuel cleaned of pollutants exits the chamber and is cooled below ignition temperature prior to contact with oxygen. The solid fuel thus purified is more appropriate for combustion, liquefaction or gasification due to the reduced costs in use as a fuel or in the post combustion clean up.

A process for advantageously efficiently treating a sulfureous combustible effluent stream by recovering the sulfur in elemental form comprises a step of combustion of the sulfureous combustible effluent stream with an oxidant gas in excess, and then a step of post-combustion of the effluents from the combustion step with an acidic gas. The stream of the post-combustion effluents, free of chemical compounds that are harmful to the efficacy of the Claus catalysts, is treated in a Claus unit, which performs the recovery of the sulfur in elemental form.

A first method includes receiving a first reflected radar signal from a target in a first field of view and receiving a second reflected radar signal from a target in a second field of view offset from the first field of view by a predetermined distance; transforming the first and second reflected radar signals to obtain first and second sets of frequency coefficients, from which a frequency-dependent phase difference is obtained; and calculating a time-delay from the slope of the frequency dependence. A second method includes obtaining summed difference values between the first and second radar responses, where each of the summed difference values corresponds to different time shifts between the first and second radar response, and deriving from the summed difference values a time-delay associated with the target's motion from the first field of view to the second field of view. A third method combines the time-delays or associated speeds obtained from independent estimators.

A nanoscale plate structure includes base plates and rib plates with nanoscale thickness and macroscopic lateral dimensions. The base plate resides in the first plane, the ribs can reside out-of-plane and form at least one strengthening rib, and additional base plates can reside in planes parallel to the first plane. The strengthening rib can be patterned such that there is no straight line path extending through a lateral dimension of the plate structure that does not intersect the at least one base plate and the at least one strengthening rib. The plates and ribs used in the structure have a thickness between about 1 nm and about 100 nm. The plate structures can be fabricated using a conformal deposition method including atomic layer deposition.

A first-half combustion period, for example, is estimated/evaluated, with a required accuracy, more simply than the conventional art, while reducing man-hours to produce a heat generation rate waveform of an internal combustion engine. Within a combustion period of an air-fuel mixture, a period from an ignition time FA to a heat generation rate maximum time dQpeakA where the heat generation rate is maximum is defined as the first-half combustion period a that is one of characteristic values of the heat generation rate waveform. The first-half combustion period a is estimated based on an in-cylinder volume at the heat generation rate maximum time, and furthermore by being corrected using an exponential function of the engine rotation speed with a value depending on a tumble ratio as exponent. Thus, the heat generation rate waveform is produced using the estimated first-half combustion period a.

A gas separation process for treating exhaust gases from combustion processes. The invention involves routing a first portion of the exhaust stream to a carbon dioxide capture step, while simultaneously flowing a second portion of the exhaust gas stream across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas back to the combustor.

In a method of reducing pollutants of a combustion engine, exhaust gas, generated by a cylinder of the combustion engine, is fed to an exhaust gas aftertreatment system as a function of a predefined condition solely via a first exhaust channel which communicates with a first one of first and second exhaust valves of the cylinder. The first exhaust channel is hereby coated, at least in part, by a thermally insulating layer selected such that a heat input is transmitted to the exhaust gas aftertreatment system which heat input is greater than a heat input in a second exhaust channel communicating with a second one of the first and second exhaust valves. The predefined condition is defined as a function of a coolant temperature of the combustion engine.

A controller is provided, which detects operating conditions of an internal combustion engine on the basis of detection results from a group of sensors and drives an actuator that modifies an opening position of a wastegate valve on the basis of the operating conditions. When driving the wastegate valve to a fully closed opening, the controller initially drives the actuator toward a preset provisional fully closed position, and after determining on the basis of a detection result from a position sensor that an actual opening of the wastegate valve has reached the provisional fully closed opening, switches a target opening to the fully closed opening and drives the actuator accordingly.

A required opening correction amount is calculated based on a target supercharging pressure and an actual supercharging pressure, a target opening is calculated based on a required opening and the required opening correction amount, an actual operating position of a wastegate valve is determined to correspond to a fully closed position when the wastegate valve is in a fully closed condition, an actual opening of the wastegate valve is calculated based on the fully closed position and the actual operating position, an operation amount of an actuator for aligning the target opening with the actual opening is calculated based on the target opening and the actual opening, and when the target opening corresponds to the fully closed condition and the actual operating position is not decreased at or above a prescribed rate, the fully closed position is updated to the actual operating position.

Illinois U.S. Representative Cheri Bustos is pushing for expansion of health insurance enrollment during the Covid-19 pandemic. She made the comment after leaving a House hearing Wednesday regarding the successor to the CARES Act. “I believe it’s shortsighted of the Trump administration not to reopen the enrollment period for the Affordable Care Act when we’re in the middle of a worldwide pandemic.” Bustos cosponsored a bill in April that would create this very enrollment period. It is currently in committee. Also after the hearing, she said a key area that needs to be included in future legislation is contact tracing of people who have been exposed to an individual with COVID-19. “If we don’t get a plan figured out for that, not just the money, but a plan, it is going to be very difficult for our country to get back into some state of normalcy," she said. "And that was clear in the hearing that we held today that that will be absolutely critical for our nation’s future.” Bustos also
