Abstract: A flush valve assembly for a water tank of a water closet which includes a first valve member which can be secured to the water tank and has a base sleeve position including a radiused inlet to thereby increase the discharge coefficient of the valve opening. A second valve member is coaxially and slidably mounted with respect to the first valve member so that the valve opening is created between the first and second valve members when the second valve member is removed from the first valve member. The second valve member is slidably movable between a first rest position, wherein the second valve member is seated on the base sleeve portion of the first valve member so that water cannot pass through the valve opening, and a second position, wherein the second valve member is removed from the base sleeve portion of the first valve member so that water can pass through the valve opening.

Abstract: A toilet includes a toilet bowl assembly having a toilet bowl and a trapway extending from the bottom of the toilet bowl to a sewage line. The toilet bowl has a rim channel provided along an upper perimeter portion thereof. In this toilet, the flush water flows through the rim channel in a path which is asymmetric and unidirectional along the entire perimeter portion thereof. The rim channel includes a plurality of rim openings distributed evenly along the perimeter of the rim channel. Flush water passing through the plurality of rim openings pre-wets the entire perimeter of the toilet bowl. The rim channel further includes a pair of water discharge slots which directs water directly into the toilet bowl in two powerful streams. The flush valve allowing passage of water from the water tank to the toilet bowl assembly is in the form of a valve inlet having a radiused port to generate greater energy throughput of the flush water.

Abstract: A power distribution system for an air handler is reconfigureable by way of selectively connectable plug-in connectors. The air handler includes a blower associated with a first plug-in connector that is selectively connectable to a second plug-in connector of a heater and a third plug-in connector of an electric air cleaner. If the air handler includes a heater but not the electric air cleaner, then the blower connector plugs into the heater connector. If the air handler includes an electric air cleaner but not a heater, then the blower plugs into the connector of the air cleaner. And if the air handler includes both a heater and an electric air cleaner, then a three-way electrical connector couples the blower to both the heater and the air cleaner.

Abstract: A sanitary mixing valve having two valve disks (1, 2) arranged in a cartridge casing (7), one of which is held in a rotationally fixed manner while the other can be moved by means of a driving element (4) provided on a spindle (3) is created, whereby the driving element (94) has at least one stop projection (5, 15) which, in cooperation with at least one stop (6, 26) on the cartridge casing (7), limits the rotational movement of the driving element (4), whereby the driving element (4) consists of a part (8), which is fixedly connected to the spindle (30) and has a gearing (9) in at least one portion of its outer circumference, and a coupling (10), which has on its inner circumferential surface a gearing (11) which, in the installed state, engages the gearing (9) of the fixedly connected part (8) of the driving element (4), whereby the minimum of one stop projections (5, 15) of the driving element (4) is provided on the coupling (10).

Abstract: A direct-fired generator for an absorption chiller includes an inner shell, in which combustion occurs, and an outer shell. The inner shell supports a tube bundle through which a first portion an absorption solution is conveyed. Combustion products makes a single pass across the tube bundle within the inner shell. Such construction minimizes the number of potential leak paths and facilitates leak testing of the generator at an intermediate stage of assembly. A flow distributor apportions solution flow to the tube bundle and to a second solution flow path which bypasses the tube bundle but which is likewise heated by the combustion occurring within the inner shell. The two solution flow paths converge after the solution flowing therethrough has been heated by the combustion occurring in the inner shell. A vapor separator disentrains solution in liquid form from vaporized solution before the vapor exits the generator.

Abstract: An air handler enclosure having a pivotal door panel covers an access opening leading to a blower inside the enclosure. The door panel is held in engagement with the enclosure when the panel is fully open or closed. The panel can completely disengage the enclosure if the panel is first pivoted to an intermediate position between the fully open and fully closed positions. However, the weight of the panel itself urges the panel to remain engaged with the enclosure as the panel pivots through the intermediate position, which helps prevent the panel from disengaging the enclosure unintentionally.
