Abstract: A pillow comprises a resilient median portion, two resilient lateral portions and sound deafening earmuffs. The median portion is adapted to receive a back of a person's head. The two lateral portions are attached to an opposite side of the median portion. The earmuffs comprise two sound deafening ear coverings and a flexible band connecting the two sound deafening ear coverings. Each one of the two lateral portion have a cavity to accommodate the sound deafening ear coverings. In use, the flexible band is operative to bias the two sound deafening ear coverings over two ears of the person.

Abstract: Apparatus and method for performing sequential batch anaerobic composting on high solids content wastes are provided, wherein a plurality of longitudinally extending trenches in the ground are employed as waste-holding receptacles, each of the trenches being provided with a cover having a peripheral skirt depending downwardly therefrom to be submerged in a water-containing moat surrounding the periphery of each trench to hermetically seal the trench. The covers contain leachate sprayers and offgas recovery piping which are connected to a fixed piping system of the apparatus, and hoppers, conveyor belts and discharge plows are used to transfer the waste into the trenches, and a lifting conveyor is used to transfer the waste out of the trenches back onto the conveyor belts extending alongside the trenches. The method involves using leachate recycling in a three stage process which employs the trenches having the removable covers.

Abstract: A furnace for the heat treating of glass, has a housing defining an elongated furnace chamber having opposite longitudinal sides and having an inlet end and an outlet end. A roller conveyor extends between the inlet end and the outlet end. The roller conveyor has a respective row of stub rollers spaced apart along each longitudinal side of the chamber, and respective conveyor rollers spanning the rows of stub rollers and cradled thereby. A respective idler pulley is disposed between each two successive stub rollers along one of the longitudinal sides of the chamber, the idler pulleys lying in a further row below the row of stub rollers. An endless drive element overshoots two successive stub rollers of the section in a respective single loop and undershoots each of the pulleys in a respective single loop between each of the two successive stub rollers to reduce the required driving power.
