With Sink Drain Stopper Interlock Patents (Class 241/32.5)
  • Publication number: 20140070036
    Abstract: An apparatus for selectively activating a food waste disposer for a sink may include a housing and an activation member. The housing may include a switch and a first magnet. The first magnet may be movable relative to the housing and the switch between first and second positions. Movement of the first magnet from the second position to the first position may cause corresponding movement of the switch from an off-position in which electrical current is prevented from reaching a motor of the disposer to an on-position allowing electrical current to the motor. The activation member may include a second magnet and is receivable in a tubular member through which waste drains and positionable relative to the tubular member to place the second magnet in proximity to the first magnet to generate a repulsive magnetic force that moves the first magnet between the first and second positions.

  • Publication number: 20100294866
    Abstract: A food waste disposer and mount system has a threaded sink flange and a food waste disposer. The threaded sink flange has a tubular body portion and a flange portion extending radially outwardly from a top of the tubular body portion. The tubular body portion has a threaded portion. The food waste disposer has an upper food conveying section that includes a housing having an upper, annular portion having a threaded portion. The upper, annular portion of the housing of the upper food conveying section is threaded to the threaded portion of the tubular body portion of the threaded sink flange when the threaded sink flange is disposed in a draining opening of a sink to mount the food waste disposer to the sink.

  • Publication number: 20030052205
    Abstract: An angle-based method and device to protect a grinding mill used for grinding material therein by rotating the drum so that the material adheres to the drum inner surface and rises therewith over a cascading angle from a gravity-balanced condition prior to detach by gravity from the inner surface and tumble into a cascading flow. The method is used for protecting the grinding mill from damages potentially resulting from the material agglomerating into a generally solidified lumped volume that could adhere to the inner surface and rotate with the latter more than the cascading angle to a fall angle wherein the lumped volume may detach from the drum inner surface and impact an impact position within the drum.
