  • Publication number: 20220017383
    Abstract: The claimed invention relates to systems, devices, and methods of using the devices for eliminating air locks by using a filter cartridge with a truncated cone shaped lid that allows air to naturally flow to the highest point of the filter cartridge. The lid including a hole for releasing air that can slow or stop the filtration process. The filter cartridge further including a foam spacer to prevent filter media from escaping the filter cartridge and allow air to be released from the hole at the top of the filter cartridge.

  • Patent number: 10435313
    Abstract: Systems, devices, and methods of filtering water include a dome shaped lid and middle disk to separate filtration media materials. The domed shaped lid eliminates air locks in the filter media that can slow or stop the filtration process. A flow control output port regulates the flow level and flow speed of the filtered water. An angled flow output port improves flow by accelerating flow at an angled bottom section of the filter. Water permeable filter bag materials house the filter media. An additional washing process improves the taste of the filtered water. A color change resin in the mixed bed resin indicates expiration of the filter. Similarly, a filter expiration indicator assists users in determining when a filter should be replaced. An integrated TDS meter is used for testing the filtered water. The devices can be used individually or in combination to provide performance improvements.

  • Patent number: 10099942
    Abstract: Systems and methods of eliminate filter air locks by maintaining a constant water table at the water head layer of the filter. The constant water table eliminates air locks in the filter as the filter drains. Water flows from the water head layer through a filtration medium in a filter cartridge, and the filtered water is output from a water outlet at the top of the cartridge. For a water table retention filter, where the water (or other liquid) being filtered, is re-directed to the top of the filter to the water head layer to avoid drawing air into the filter. Unfiltered water drains down the center of the filter to the water head layer and then flows up through the filter and is directed out near or at the top of the filter.

  • Patent number: 6318490
    Abstract: A cruise control for a vehicle having a throttle controller mounted to a handlebar is provided. The cruise control includes a throttle-pipe handle having a throttle-pipe spur gear attached thereto, a cruise control spur gear coupled to the throttle-pipe spur gear, an electromagnetic brake/clutch device coupled to the cruise control spur gear, an activation switch, and a control circuit. The cruise control spur gear may be coupled to the throttle-pipe spur gear via an intermediate spur gear. The control circuit provides a control signal to activate the electromagnetic brake/clutch device when the activation switch is actuated. When activated, the electromagnetic brake/clutch device prevents rotation of the throttle-pipe handle. When the braking system of the motorcycle is activated, the control signal provided to the electromagnetic brake/clutch device is removed, which deactivates the brake/clutch device, allowing free rotation of the throttle-pipe handle.
