enclosing the porous membrane and the chambers. Combustion fuel is supplied to the porous membrane so that surface combustion takes place at the surface of the porous membrane facing the chamber for burning the refuse contained in the chamber. Electrical means may also be employed to provide combustion of the refuse. Safety features include pressure feed-back means for monitoring and regulating the pressure within the apparatus and temperature feed-back means for monitoring and regulating the temperature within the apparatus. A particle bin is positioned below the chamber for receiving burned particles from the chamber. The gases generated from the burning refuse is collected and pumped through a super heating and purifying chamber (eliminated all hazardous affluent) and into the boiler type heat exchanger and thereby producing steam for electrical generation. The electricity produced is then partially used to run a cryogenic plant which produces liquid oxygen which is used to produce oxygen gas, the major fuel component, used to produce the surface combustion used in the incinerator. Therefore a t&generation system is generated which reduces operating cost, increase operating efficiency of the incinerator and the biproduce sold to others generate an off-setting income.
5289716 MONITORING AND ANALYZING WASTE GLASS COMPOSITIONS Schumacher Ray F The United States of America as represented by the United States Department of Energy A device and method for determining the viscosity of a fluid, preferably molten glass. The apparatus and method uses the velocity of rising bubbles, preferably helium bubbles, within the molten glass to determine the viscosity of the molten glass. The bubbles are released from a tube positioned below the surface of the molten glass so that the bubbles pass successively between two sets of electrodes, one above the other, that are continuously monitoring the conductivity of the molten glass. The measured conductivity will change as a bubble passes between the electrodes enabling an accurate determination of when a bubble has passed between the electrodes. The velocity of rising bubbles can be determined from the time interval between a change in conductivity of the first electrode pair and the second, upper electrode pair. The velocity of the rise of the bubbles in the glass melt is used in conjunction with other physical characteristics, obtained by known methods, to determine the viscosity of the glass melt fluid and, hence, glass quality.

An animal confinement building includes an upper animal floor and a lower animal waste pit having a lower floor. Scrappers are mounted on a continuous cable movable back and forth the length of the lower pit floor. Controls for the cleaning system are mounted on a wall in the area of the upper floor out of the corrosive environment
