  • Publication number: 20220401979
    Abstract: A backpack material dispenser that includes a pumpless pressure tank for storing and discharging a material under pressure contained in the pressure tank and a hose and a shut off valve connected to an output opening of the pressure tank for allowing flow of the material from the pressure tank under pressure and through a nozzle communicating with a discharge end of the hose. A discharge valve communicates with the nozzle proximate the hose for allowing controlled discharge of the material from the nozzle. A backpack assembly mounts the pressure tank for being carried by a user. A charging tank contains a gas under pressure to charge the pressure tank to a predetermined pressure, and a releasable connector of the charging tank attaches to a complementary connector of the pressure tank for charging the pressure tank with the gas under pressure to the suitable pressure tank pressure.

  • Patent number: 11015376
    Abstract: A security lock for a door is provided having a bracket on the interior side of the door with a locking bolt mounted in the bracket. The bolt is adapted for movement between a raised, unlocked position above a cavity on the floor below the bracket and a lowered, locked position where the bolt is in the cavity to prevent the door from being opened. A bolt restraint is mounted on the bracket and cooperates with the bracket to maintain the bolt in its unlocked position. The bolt restraint, for example, a spring-loaded ball that engages an annular recess in the bolt, releases the bolt into its locked position when a downward force is applied to the bolt. The locking bolt has an enlarged flange that stops movement of the bolt into the cavity beyond a predetermined location on the bolt.

  • Patent number: 6896017
    Abstract: There is provided a rotatable cutting tool for supporting at least one knife in at least two alternate angular cutting configurations. The cutting tool includes a body that defines at least one cavity extending generally in a longitudinal direction of the body. Each cavity is defined by first and second knife support surfaces, which are provided in an opposing, non-parallel configuration. The first knife support surface is configured to support one of the knives that is urged against the first surface at a first hook angle, and the second knife support surface is configured to support one of the knives that is urged against the second surface at a second hook angle, which is different from the first hook angle.
