Abstract: A method for improving the manufacture and reliability of new, remanufactured, repaired or reconditioned Fire Control Radar APG-68 tactical radar systems (FCR) utilized in military aircraft and providing such units with extended useful life expectancies equivalent to or better than new of the FCR APG-68 unit high frequency, high voltage dual mode radar transmitters that are deployed in over 1000 state-of-the-art military aircraft such as the F-15, F-16 and F-18 fighter aircraft, and B-1 bombers. The novel method extends the mean lifetime of previously repaired and repairable FCR APG-68 tactical radar units and radar units and ageing transmitters from about 100 to a few hundred hours to about five hundred or more hours by the step of removing embedded moisture and absorbed moisture from the heterogeneous electronic components in the FCR APG-68 tactical radar unit.

Abstract: An upper cabinet of a rotary-drum laundry dryer outer casing can include a rear wall. The rear wall can include a sink-shaped bulge or recess. The bulge or recess can project outwards of the upper cabinet, be roughly centered to a rear rim of a dryer drum, and include a through opening. The upper cabinet can also include a substantially circular, basin-shaped lid or cover fixed to the inner face of the cabinet rear wall substantially coaxial to the drum. The lid or cover can be shaped so as to completely cover and close the outwards-projecting bulge or recess on the cabinet rear wall. This can form, on that rear wall, a cavity which communicates with the inside of drum and also with a hot-air generator via the through opening.

Abstract: The present disclosure provides, among other things, a system and process for drying a biosolid or sludge, such as wastewater sludge. The system and method include a fluidized bed dryer in which the sludge is dried. The fluidized bed includes bed media. In particular examples, the bed media is different than the sludge. The system and method can include additional features, such treating the sludge using a thermochemical process in a thermochemical reactor, such as a gasifier, to produce a fuel.

Abstract: A hand drying apparatus has a casing, a cavity formed in the casing for receiving a user's hands, a fan located in the casing and creating an airflow, and a plurality of openings communication with the fan and arranged to direct an airflow transversely across the cavity. The cavity has an entrance delimited by a front edge and a rear edge in which the openings are located. The shape of the front and rear edges is such that, when in use the user's hands are introduced to the cavity, the distance between the user's hands and the nearest opening is substantially uniform. Alternatively, one of the edges is substantially straight and the other of the said edges is curved so that the distance between the edges varies along the length of the cavity entrance. These arrangements enhance the drying efficiency of the dryer.
