  • Patent number: 6123843
    Abstract: A system is provided for treating water to reduce calcium carbonate deposits. At least three or four pairs of magnets (30a-30d and 32a-32d in FIG. 2) form a group of magnets that are mounted around a water-carrying pipe (12), with the magnets spaced apart parallel to the length of the pipe, and with the magnets of each pair lying on opposite sides of the pipe. Each pair of magnets (e.g. 30a, 32a) and a frame (34) that holds them, forms a unit which clamps individually around the pipe, to facilitate changing of the spacing between adjacent magnets. Two different groups of magnets (16, 18) can be employed, with the spacing of magnets in a first group being nonharmonic to the spacing in a second group.

  • Patent number: 5636019
    Abstract: A method and apparatus are provided that indicate the amount of gas such as air in a clear liquid such as water. The apparatus includes a transparent pipe (60), an input coupling (16) at a first end of the transparent pipe, and a shutoff valve (20) at the second end of the pipe. The first end of the pipe is connected to a source of water (12) under pressure, whose air content is to be determined. With the valve (20) open, water is allowed to pass through the pipe and valve to purge the pipe of air and any previous water. The shutoff valve is then closed, to contain the water under pressure. The dissolved air in the static, pressurized water, immediately forms microscopic air bubbles, which result in the water having a "milky" appearance. The presence of the milky appearance indicates the presence of a considerable amount of dissolved water (when the water is not under high pressure). The reflectivity of the water indicates the amount of dissolved air per unit volume of water (when not under high pressure).

  • Patent number: 5042095
    Abstract: An apparatus is provided which enables a container of cleaning fluid to lie in a water closet and dispense cleaning fluid solely into the toilet bowl rather than into the water closet. The apparatus includes a storage chamber (54) for holding granules of a chemical that dissolves in water to create cleaning fluid, and a transfer chamber (64) through which water flows from a refill valve outlet (40) into a standpipe (44) that leads to the toilet bowl, at each flushing of the toilet. The transfer chamber is coupled to the storage chamber so that cleaning fluid can migrate from the storage chamber (54) into the transfer chamber (64), and yet during each flushing the water from the refill outlet primarily sweeps out cleaning fluid in the transfer chamber. An anti-siphon device (74) between the refill valve outlet and the cleaning fluid dispensing apparatus includes a check valve, and a chamber that surrounds the check valve.

  • Patent number: 4938245
    Abstract: A toilet refill valve is described for refilling a water closet after each flushing, which produces minimal noise during the refill process. The valve includes a valve device which can open to pass water to a vertical outlet tube that empties into the bottom of the water closet. An anti-siphon air tube near the top of the outlet tube has an upper end open to the atmosphere and a lower end facing downwardly along the outlet tube. A restriction in the outlet tube below the air tube, causes water to fill the outlet tube and at least the bottom of the air tube for a water inlet pressure of at least 20 psi. The water at the bottom of the air tube prevents air from being dragged into the downwardly facing air tube, to avoid the noise that would result from such air flowing through the air tube and bubbling out of the bottom of the outlet tube.

  • Patent number: 4907302
    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.

  • Patent number: 4108202
    Abstract: An end of an inlet tube communicates through a tank wall with a water supply and an inner end of the inlet tube communicates through a float controlled valve with a generally vertically downwardly extending outlet tube. Thus, the tank water level through the float controls closing and opening of the valve admitting water through the inlet tube, through the valve and down the outlet tube flowing into the tank from the outlet tube lower end. The outlet tube is selectively vertically adjustable to adapt to various depths of tank by being formed of telescoped parts normally retaining a determined telescoping by a projection of one part being radially interengaged in a groove of the other part. Depending on the particular construction, the tube part telescoping may be selectively varied by either relative rotation between the parts or by disengaging and reengaging the interengagement between the parts. Through a slot and lock collar arrangement, the tube parts may be totally telescopically separated.

  • Patent number: 4100928
    Abstract: Telescoped inlet and outlet tubes having a valve between upper extremities thereof are each formed with end telescoped, upper and lower parts, the tube upper parts being assembled movable together and the tube lower parts being assembled movable together for simultaneously increasing and decreasing the respective tube end telescoping to selectively change the overall height of the ball cock. Positive securement in a height adjusted position against straight vertical relative movement is obtained by positive radial interengagement between the outlet tube parts with either selective relative rotation or selective release of the interengagement with re-engagement providing the height adjustment. An upper main case covers the valve assembly and an inner end of a float connected valve actuating lever projects into the upper main case to a case slot, being pivoted therein and operably connected to the valve.

  • Patent number: 4080986
    Abstract: An essentially closed hollow body of the float receives liquid in a lower portion for ballast and air in an upper portion for floatation with a vertical guide sleeve therethrough being offset at one side of the hollow interior slightly spaced inwardly of a part of the body sidewall. A liquid and air flow opening is formed through the body sidewall part horizontally centered relative to the guide sleeve so that flow paths are created segregated approximately one half around either side of the guide sleeve. By arcuately forming the body interior and the guide sleeve, not only are the flow paths smoothly arcuate, but the circuitous nature thereof muffles echoing sounds created within the hollow body from passing outwardly of the body through the flow opening.
