Abstract: A toilet system comprising a bowl, a treating chamber, a trap connecting the bowl to the treating chamber, said trap containing a bypass to a waste pipe, a conductor connecting the treating chamber to the waste pipe, a hydraulic attrition member in the treating chamber for particulizing effluent delivered into the treating chamber, a worm pump in the treating chamber for evacuating effluent from the bowl into the treating chamber and discharging the treated effluent into the waste pipe, a valve connected to the bowl for supplying flush water thereto and control means operable to initiate operation of the pump followed by operation of the valve and stop the pump prior to closing of the valve and wherein, in the event the pump is disabled, discharge from the bowl can be effected through the bypass by delivery of fluid into the bowl.

Abstract: A filter system wherein there is a first chamber containing fluid at a predetermined level, a shroud positioned in the first chamber immersed in the fluid, said shroud defining a downwardly-open second chamber, a quantity of discrete, buoyant bodies supported in the shroud by flotation, said discrete, buoyant bodies defining a filter media, a conduit connected to the top of the shroud for delivering fluid to the shroud at a pressure to displace the discrete, buoyant bodies downwardly therein as the fluid is forced downwardly into the shroud and into the lower part of the first chamber below the shroud, a second chamber surrounding the first chamber, a conduit connecting the top of the shroud with the second chamber, a conductor connected to the bottom of the second chamber providing an outlet from the bottom and valves in the several conduits operable on the one hand to admit fluid into the shroud and to permit fluid to be withdrawn from the third chamber while blocking flow of fluid from the first chamber to

Abstract: A filter module wherein the fluid to be filtered is projected into a chamber containing a floating bed of buoyant bodies confined within the chamber at the top side and wherein the point of entry of the fluid is constantly moved about the center of the bed so that successive portions of the bed are subjected to weltering while the remainder is quiescent such that the solids are separated from the bodies dispersed by weltering and gravitate to the bottom of the module and are drawn off and the filtrate is drawn off through the quiescent portion of the bed at the top.

Abstract: A system for collecting solar energy in the form of heat in liquid at low temperature, raising the temperature by vapor compressor means and by heat transfer means storing the heat energy at a temperature which is higher than the temperature originally obtained from the solar heat collector.

Abstract: A leak detection system capable of efficiently dry-testing containers such as steel drums of large capacity. The system includes a test station constituted by a hermetically-sealed chamber adapted to receive a container to be tested and provided with a retractable head coupled to an external fill assembly. The head functions to sealably engage the bung hole or other container opening and to fill the container with pressurized air, the pressure within the container being maintained during the test period at a constant level, whereby physical distortion of the container is controlled. The pressure within the test chamber is sensed and the output of the sensor is applied to a data processor wherein the influence of temperature on the test chamber pressure is discounted by means of a waveform scanning technique, making it possible to determine the extent to which the container under test is heated and to predict the error pressure in the chamber due to thermal effects.

Abstract: A vapor compression distillation system utilizing a two stage vapor compressor comprising a rotary positive displacement first stage compressor backed by a second stage liquid ring compressor.

Abstract: A novel sewage treatment system and components thereof are presented providing in site separation of solids from liquid, incineration or other disposal means of solids, and treatment and purification of the liquid effluent.
