Abstract: To reduce the barrier sealant amount, the area of a throat (88), communicating an inlet compartment (78) to an outlet opening (64), is made small. Should sealant not be in the throat, wastewater in the throat would be correspondingly small. A snorkel (110) in a discharge section drain tube (98) extends downwards to above the level of the horizontal drain, and allows any air from the external drain to pass to the outlet compartment generally below the ceiling (90) so that, should wastewater cover the opening of the drain tube, such air is permitted to enter into the cartridge and to prevent any syphoning. A three rib channel guide mechanism (100) within the tube guides wastewater flow towards the drain tube center, and away from the drain tube walls to avoid deposit of any sediment contained in the wastewater.

Abstract: There are provided a generator internal pipe section that extends in the horizontal direction inside a steam generator; and a communication pipe section that is connected to the generator internal pipe section and is provided with a communication path, wherein one end of the communication path is connected to the pipe path at an upper end of a cross-section perpendicular to the flow direction of the cooling water in the pipe path and the other end of the communication path is positioned at the downside in the vertical direction in relation to one end of the communication path, and wherein one end side and the other end side of the communication path are connected at a position existing at the upside in the vertical direction in relation to one end.

Abstract: In a urine cartridge or wastewater trap, equalized pressures and increased flow rate between its inlet and outlet compartments increases the life of the cartridge. The pressure equalizing is effected by placement of a separator between the two compartments to provide them with substantially equal volumes. The increased flow rate is created by a uniquely configured baffle positioned adjacent a pan at the bottom of the cartridge. The baffle configuration is shaped to provide a constriction that increases the flow velocity of the urine so that the fluid flow effects a channel along the bottom pan and through any solids deposited on the bottom pan. A diverter may be placed above the centrally located entry to the inlet compartment to create a circuitous path for preventing a disturbing impingement of the urine onto the sealant contained in the inlet compartment.

Abstract: A diverter (170, 270) atop the upper wall (110) of a cartridge (100) and over the opening (114, 115) therein avoids direct access of urine to the opening and the sealant (105) within the cartridge. The diverter is spaced by standoffs (182, 282) from the upper wall to provide a urine flow passage. A float (274) can be incorporated in the diverter to provide a visible signal of the presence of collected urine on the cartridge upper wall. A pre-treatment chemically-constituted tablet (210) held by a retainer (200) in the diverter provides sanitizing and/or deodorizing means. Post-treatment chemically-constituted tablets (224a) or pellets (224b) placeable at the outlet of the cartridge protect the drain pipe from corrosion and other harm.

Abstract: This invention prevents blockage that occurs in the general drainage traps of buildings. The invention consists in connecting a conduit by positioning it in the inlet part above the trap water float level (M) and in the outlet part below a line (N) thereby forming a new auxiliary trap. The invention is suitable for use in traps in buildings which are connected to the common sewage system. The invention informs and thereby prevents the obstruction of the trap by the use of an alarm which is installed in the conduit wherein the water is diverted due to gravity when the conduit is obstructed and signals any obstruction in the conduit so that it can be cleared without waiting for the consequences of such a situation to occur. Also although water flows freely through the auxiliary trap section air does not freely communicate between the inlet and outlet pipes and foul odors are avoided.

Abstract: The purpose of the invention is to prevent the blockages that occur in the general drainage traps of buildings. The invention consists in connecting a conduit by positioning it in the inlet part above the trap water float level (M) and in the outlet par below a line (N), thereby forming a new auxiliary trap. The invention is suitable for use in traps in buildings which are connected to the common sewerage system. The invention provides a technical solution that prevents the obstruction of the trap by means of an alarm which is installed in the conduit wherein the water is diverted due to gravity when the conduit is obstructed. Said alarm signals any obstruction in the conduit so that it can be cleared without waiting for the consequences of such a situation to occur. Other versions of the invention consist in installing said conduit in the upper or lateral part of the trap, on the connection points indicated.
