Abstract: A toilet venting system adaptable to a conventional water closet, comprises a vent-pipe connecting a toilet bowl with a water flushing tank. The latter is provided with a sealing. When after the use of the water closet, water is let to rapidly escape and flow from the water flushing tank into the toilet bowl, a partial vaccum or negative pressure is created in the water flushing tank. As a result, an upward current occurs, foul smelling air and gases being drawn from the toilet bowl into the water flushing tank. By contacting the wet surface of the interior walls of the latter, and especially, the surface of the water therein, a substantial condensation of the foul smelling gases takes place.

Abstract: A PSA process and system utilizes a combination of cyclic feed, evacuation, purge, and repressurization steps to provide a final gas product enriched in one of the feed components. The process is carried out in a simple system which utilizes a single two-way four-port valve for controlling gas flow between an adsorber vessel and a blower, and the blower is used for the introduction of feed gas into the adsorber and the evacuation of gas from the adsorber. The control of gas flow in either direction between the adsorber vessel and a product gas storage tank is accomplished by two check valves installed in parallel between the vessel and the tank.

Abstract: A method for enhancing the dielectric properties of an electrical cable having a central stranded conductor encased in a polymeric insulation. The cable defines an interstitial void space (v1) between the strands of the conductor. The volume (v2) of a dielectric enhancement fluid required to be absorbed by the cable to reach a predetermined level of dielectric enhancement is determined. The ratio of (v1/v2) is computed. If the ratio of (v1/v2) is greater than a maximum ratio of 1.4, then a quantity of the dielectric enhancement fluid is diluted with a sufficient quantity of a diluent to produce a mixture of diluent and dielectric enhancement fluid, such that when the volume (v1) of the mixture is supplied to the cable interior, the cable will have been supplied with a volume (v3) of the dielectric enhancement fluid within the mixture such that (v3/v2) is less than 1.4. The diluent is substantially insoluble in the polymeric insulation, has a sufficiently low initial viscosity to enable introduction into the cable interior, and is miscible with the dielectric enhancement fluid.
