  • Patent number: 11918026
    Abstract: An aerosol generating article (10) for use with an aerosol generating device includes an aerosol forming substrate (20) an aerosol cooling element (40) and an acid. The article may optionally include one or both of a filter and a support element (30). The aerosol cooling element, the filter, if present, and the support element, if present, are downstream of the aerosol forming substrate. The acid is downstream of the aerosol forming substrate and is positioned to interact with aerosol from the aerosol forming substrate when the aerosol generating article is used with the aerosol generating device. The acid may be in or on one or more of the aerosol cooling element, the filter, and the support element. The acid may selectively remove ammonia from aerosol generated by the article during use.

  • Patent number: 10992117
    Abstract: One embodiment is directed to a tool to cut and strip a radiating coaxial cable. The tool comprises first and second jaws, a linkage that couples the first jaw to the second jaw, a cutting blade, and a stripping blade. The tool is configured to position at least a portion of the cutting blade to cut and sever the cable at a first point along the cable when the tool is rotated around the cable while the first jaw and the second jaw are closed around the cable. The tool is configured to position at least a portion of the stripping blade to cut the jacket of the cable, without severing the cable, at a second point along the cable when the tool is rotated around the cable while the first jaw and the second jaw are closed around the cable. Other embodiments are disclosed.
