Medium temperature (500 degrees F.-II00 degrees F.) wet off-gases from the final drying zone of counterflow incineration of waste sludge are scrubbed and cooled before heating to final high temperature in an afterburner and the resulting hot dry gases are used to preheat the scrubbed and cooled gases prior to entry of said gases into the afterburner.
used to determine the complex dielectric constant of the fluid in a pipeline. Water salinity and an adjustment to the mixing formula are calculated using X-band and S-band sidewall links. The overall water content of the pipeline can then be determined by using as S-band main link that transmits a wave through a representative portion of the entire pipeline.

METHOD FOR TREATING WASTEWATER SLUDGE
METHOD OF AND APPARATUS F O R D R E D G I N G S L U D G E IN HIGH DENSITY
John P Nicholson, Jeffrey C Burnham assigned to N-Viro Energy Systems Ltd A method of decontaminating wastewater sludge to a level that meets or exceeds USEPA Process to Further Reduce Pathogens standards, wherein lime or kiln dust and/or other alkaline materials are mixed with wastewater sludge in sufficient quantity to raise the pH of the mixture to 12 and above for a predetermined time and drying the resulting mixture.
4902890 RODENT MONITORING APPARATUS William C Biehle A rodent monitoring apparatus comprises a passageway defined by a horizontal member and two vertical members, an infrared light beam directed across the passageway, and an electronic counter circuit configured to monitor the number of times the light beam is interrupted.
4902961 MICROWAVE SYSTEM FOR MONITORING WATER CONTENT IN A P E T R O L E U M P I P E L I N E R De Bibhas, Paul L Donoho, David E Revus, Russell Boyer assigned to Chevron Research Company A method and apparatus for determining the water content of crude oil in a pipeline is disclosed. The device consists of S-band tarnsmitting and receiving antennas, and X-band transmitting and receiving antennas. These are
Yutaka Nishikawa, Higashimurayama, Japan assigned to TOA Corporation A method of and apparatus for continuously dredging sludge deposited on an underwater bed, at a high density of the sludge, according to which digging and scooping devices are placed in an airtight hood opened at its bottom, which is applied on the intended underwater bed and into which air is then introduced to obtain a condition in which water is removed out of the hood, and the digging and scooping devices are then put into operation, whereby dredging is effected at a high efficiency in that the content of water in sludge being dredged is suppressed to a minimum, the sludge being transferred under pressure in a state of containing substantially no additional water than it naturally contains.
4903759 APPARATUS AND METHOD FOR MONITORING AND CONTROLLING HEATING AND/OR COOLING SYSTEMS John G Lapeyrouse This invention relates to an apparatus and method for monitoring and controlling a heating and/or cooling system which controls the temperature of air in a conditioned space within a building and to such an apparatus and method capable of indicating the performance of such a system and effectuating control over the system for maximizing the operating efficiency of the system. As compared with a conventional control system, additional temperature sensors are provided to sense the temperatures of air drawn into and discharged from a temperature modifying unit such as an air handling unit
