Abstract: A pivotable toilet flush valve member (10) is provided, of the type that includes a float (40) with a pair of holes (44, 52) that allow the float to fill with water during a flushing to close early, and where the float can be turned to vary the amount of water used during a flushing, wherein the float is constructed for easy and loose mounting on a frame (12) and for low friction rotation about a primarily vertical axis (60), and where the flush valve member has a simple detent mechanism to hold the float at any rotational position to which it is turned. The frame has an aperture (74) lying along the primarily vertical axis, and the float has a small diameter upwardly extending projection (70) that projects upwardly through the frame aperture and that is held by the walls of the aperture, for low friction turning. The detent mechanism includes an upstanding wall (100) with an upwardly-open vertical groove (102) that has a plurality of teeth on at least one side of the groove.

Abstract: An improvement is provided for toilet flush valves on tanks which contain insufficient water to flush properly, which leads to waste of water by double flushing. The improvement enables in-field modification of the flush valve to substantially completely empty the tank. A closing delay device (42, FIG. 1) which includes a cup (64), is attached directly to the top of the tank ball (32) for easy installation, and is tall enough so that when the tank ball is pivoted to the fully opened position the cup is pivoted to a side of the pivot axis (28) opposite the tank ball to delay closing of the flush valve. The tank ball is formed of soft rubber and has an upwardly extending tubular extension (74) with an annular groove therein, which closely receives an annular flange at the bottom of the delay cup device.

Abstract: An air regulated cleaner discharge device is for use in a toilet water tank, the tank having a ballcock for discharging water to fill the tank from a minimum water level to a maximum water level, a flush valve connected to a toilet bowl for flushing water therein from the tank, and an overflow pipe projecting above the maximum water level having a ballcock refill tube connected thereto for directing tank water to refill the toilet bowl after flushing. The novel device has a preferably plastic container for receiving a mixture of liquid or other chemical material therein with an air supply tube having an inlet end opening into the tank spaced above the minimum water level and below the maximum water level, and an outlet end opening into the container preferably at an extreme upper portion above the minimum water level. A liquid cleaner supply tube also preferably of plastic is connected into the container at preferably an extreme lower end portion thereof and particularly below the air supply tube outlet end.

Abstract: Improved ballcock float structures are provided including a molded, plastic, hollow body formed of cup-like lower and reverse cup-like upper parts. The parts are retained together by snap engagement between the extremities of the parts with positioning abutments for additional stability. A float guide extends vertically through the body having a vertical opening for receiving a ballcock or the like to be controlled by the float. Control of the float for controlling the ballcock is provided by two, tubular liquid vents secured in and extending upwardly from the lower part bottom wall and a similar liquid vent projecting downwardly through and from the upper part top wall. The liquid and air vents project into the interior of the body, but terminate spaced apart and the relative positions thereof determines the performance of the float.

Abstract: The pressure activated cleaner discharge device is used in a standard toilet water tank, the tank having a ballcock for discharging water to fill the tank from a minimum water level to a maximum water level. The tank also includes a flush valve connected to a toilet bowl for flushing water therein from the tank, and an overflow pipe projecting above the maximum water level having a ballcock refill tube connected thereto for directing a pressure flow of tank water to refill the toilet bowl after said flushing. The cleaner discharge device includes a container in the tank having an inlet and outlet, an inlet water tube connected between the refill tube and the container inlet, and an outlet cleaner tube connected between the container outlet and the refill tube downstream of the inlet water tube connection. The refill tube and its connections and the container and its connections are all liquid-tight from the ballcock to the refill pipe substantially throughout the downstream flow of water therein.

Abstract: A conventional hot water heating system generally of the type for heating water in multiple units of hotels, motels, schools and the like and using any heating medium has a processor and control assembly which is operationally connected to at least a water temperature sensing means and a heating control means thereof. The processor and control assembly divides the time into exact time periods, say one-half hour, and the time periods are grouped into a group of consecutive time periods, say a week. Taking any individual time period, the time periods are checked around the time period which the present time period is a repeat and time periods directly preceding the present time period, and the operational water temperature for the present time period is chosen, as well as the amount of heat required to maintain the water at that temperature on a percentage basis of heating taken from one hundred percent.

Abstract: In an electrode of the type having a reservoir for containing a reference electrolyte solution and a liquid junction for effecting electrical communication between said reference electrolyte solution and a sample solution, and including a seat and plug valve assembly of the electrode in communication with the reservoir and a sample solution, an improvement characterized in that a resiliently stressed spring contained within the reservoir biases the plug axially into mating engagement with the valve seat, and in that, upon application of displacement pressure axially against the plug, the latter automatically twists, axially, to execute a partial turn so that a valve-closing face of the plug laps or wipes against the seat and concurrently moves from engagement with the valve seat to open the valve assembly for fluid flow and cleansing flushing therethrough.
