APPARATUS AND PROCESS FOR PRODUCING AN ORGANIC PRODUCT FROM SEWAGE SLUDGE
SELECTABLE TOILET-WATERLEVEL FLUSHING SYSTEM
Quentin Hampton A completely integrated and automated apparatus by which liquid sewage sludge from any sewage or waste treatment plant may be processed into a completely dry, pelletized and sterilized product of an organic nature containing nutrients valuable for the support of plant life. The apparatus involves one completely integrated and automated unit together with a control center by means of which electric circuits program each component of the apparatus to automatically regulate the operation of each component, so that no labor or other manpower is required in the operation, except for observation, lubrication, maintenance and repair of the various motors and machineries involved.
Robert A Richter A selectable toilet-water-level flushing system (10) that allows a toilet user to selectively control the quantity of water that is used for a toilet flush. The quantity of water used depends on whether liquid or solid waste is to be flushed. For liquid waste, only a partial flush is necessary; for solid waste, a full-flush is used. The system (10) functions by performing a simple modification to the toilet flush valve (12). The modification consists of inserting into the valve opening a weight (16) that causes the normally buoyant valve to become non-buoyant. Since the valve is non-buoyant, the lifting of the valve from the valve seat (36) is totally controlled by the toilet flush handle (38) which, in turn, is controlled by the user. Typically, for a partial flush the handle (38) is temporarily held in its depressed position for two seconds while for a full flush, it is held for four seconds. Over a period of time, by using partial flushes a large savings of fresh water can be realized.
331104 COMBINED BURNER NOZZLE, NOZZLE-SUPPORTING HEAT EXCHANGE BLOCK, AND CONTROL VALVE SUBASSEMBLY UNIT FOR A WASTE OIL BURNER Glenn Bender assigned to Shennandoah Manufacturing Co Inc The ornamental design for a combined burner nozzle, nozzle-supporting heat exchange block, and control valve subassembly unit for a waste oil burner, as shown.
5129335 FLUID WASTE BURNER SYSTEM Eddy Lauwers, Kalmthout, Belgium assigned to Union Carbide Industrial Gases Technology Corporation A process for controlling the temperature and flame front in a liquid waste incinerator comprising: dispersing fluid wastes into the flame of at least one oxygen/fuel burner to incinerate the waste in and around the flame, wherein flame energy is regulated by adjusting the fuel to the
