  • Patent number: 11511234
    Abstract: The present disclosure relates to a vacuum filter that incorporates a large area pleated filter element having pleated hydrophilic membrane configured along slanting surface in pyramid shape and incorporated with in a filter housing that can be accommodated in neck of a filtrate container. The disclosed configuration reduces overall height of the filtering system improving its stability and reducing space requirement. Further, top portion of the filter housing is configured to receive either a feed cup for direct feeding of feed liquid by pouring in the cup or a fitting with tube that can be used to suck the feed from a feed solution container under action of a vacuum thus allowing universal use. In another embodiment, a single hydrophobic membrane is provided to avoid problems of low flow due to bubbles coming with the feed solution and also to allow restart of filtration without air lock.

  • Patent number: 11504657
    Abstract: A filter assembly and a method of operating the same to detect water leaks are provided. The filter assembly includes a filter housing for receiving a filter cartridge and at least partially defining a drain trough positioned below the filter cartridge for collecting leaked water. A light source is positioned proximate the drain trough for directing light through the drain trough and a light sensor is positioned proximate the drain trough for sensing the light directed through the drain trough. A controller uses the light sensor to monitor the light generated by the light source and determines that a leak exists when an intensity of sensed light is reduced by the leaked water.

  • Patent number: 11485912
    Abstract: Existing approaches to refuse handling are all based on historical approaches which rely on a network of refuse collection vehicles collecting waste from individual households and delivering this to a centralised landfill or MBI location. This is highly undesirable and wasteful. An alternative process is disclosed, relying on the thermal treatment of waste and like products produced or brought in to the residential property and processed within the domestic curtilage to produce fuel or other forms of energy. Thus, domestic waste will be thermally treated at the home instead of being collected by local authorities and disposed of. The waste input put material will be loaded into a domestically engineered thermal conversion unit either directly or after a pre-process such as shredding. The feedstock will be converted into fuels by a thermal treatment, such as pyrolysis.

  • Patent number: 11266825
    Abstract: A manual clot aspiration and filtration system enables a method of removing a clot without general anesthesia and the expense of an operating room. An aspiration and filtration system for bodily fluid utilizes a syringe coupled with a filter unit to draw bodily fluid through the filter unit to collect debris on the filter. A flow valve may then be turned and the plunger depressed to force the filtered fluid back into the body. The filter may be configured to capture particles such as blood clots and plaque. The filter unit has a cover that can be removed for inspection and/or removal of the collected debris. When the cover is replaced, trapped air may be removed by turning the flow-valve to a purge direction and pressing the plunger into the syringe to force fluid back toward the filter unit to purge the trapped air through the purge valve.
