  • Patent number: 12648565
    Abstract: Some embodiments relate to herbicide compositions and methods of inducing phyotoxicity in a plant, by administering an aqueous composition to foliar portions of the plant. This aqueous composition includes at least one nutrient, and at least one adjuvant, and has a pH of about 4 to about 7. In some embodiments, the aqueous composition comprises an organic or mineral acid. In some embodiments, the phytotoxicity is topical. In some embodiments, the phytoxicity is systemic. Without being limited by theory, the nutrient is absorbed by the plant in excess, thereby killing the plant.

  • Patent number: 5121929
    Abstract: A load sensing gasket having a gasket body defining a service opening for fluids and having a load sensor encased in a cavity in the body. The gasket body comprises a first gasket layer providing a first outer gasketing surface and a first inner surface, a second gasket layer providing a second outer gasketing surface and a second inner surface, the inner surfaces together defining the cavity and side walls for defining a perimeter for the cavity. The load sensor includes confronting electrodes and a pressure sensitive electrically resistive material between the electrodes and conductors extending outwardly of the perimeter. A seal between the first and second gasket layers around the load sensor seals the electrodes in the cavity from fluids when the gasket is in use.

  • Patent number: 4676515
    Abstract: A gasket, such as an exhaust manifold gasket, having improved recovery, sealability and stiffness characteristics. The gasket has two embossed metallic layers and an intermediate compressed expanded graphite layer having a density of at least about 70 pounds per cubic foot. The embossments of the metallic layers are vertically aligned, the vertically aligned embossments extending in the same direction. The embossments are positioned around a clear-through service aperture.

  • Patent number: 4544169
    Abstract: A high temperature resistant gasket assembly comprises a metallic sheet member defining a plurality of openings, including at least two bolt holes through which bolts are adapted to pass and at least one high pressure opening for surrounding a high pressure zone to be sealed. The metallic sheet member defines a surface zone adjacent the high pressure opening. A metallic wire is disposed on a surface zone of the metallic sheet member closely adjacent to the high pressure opening to effect a seal at the surface zone. Preferably, the metallic sheet is of a low carbon steel and the wire is a copper wire. A second metallic sheet member of substantially the same shape, form and material as the metallic sheet member may be positioned to overlie the metallic wire, and to confront the first sheet member to form a sandwich with the wire between the sheet members. The second sheet member has a second surface zone complementary to the first surface zone.
