  • Patent number: 10952833
    Abstract: A spring mechanism for attaching to a power device drive unit includes a housing connectable to a portion of the power device and a shaft extending through the housing. One end of the shaft is coupled to a workpiece and a bottom member extends from the other end and is positioned adjacent the drive unit. The bottom member includes at least one of a ferromagnetic material and a permanent magnet. The bottom member, shaft and workpiece move upon actuation of the drive unit, and a spring extends laterally outwardly from the shaft between the shaft and the housing. The spring is affixed to one of the shaft and the housing, wherein the spring bends between a deformed position and a return position upon the movement of the bottom member.

  • Patent number: 6971560
    Abstract: An actuator assembly is disclosed which can dispense chemicals, such as insect control ingredients, from an aerosol container. The actuator assembly is mountable to the aerosol container and includes a solid plug that, upon initial activation, will be caused by the pressure of the chemical in the aerosol container to move to an unsealed position. Movement of the plug is retarded by a frictional engagement of the plug with an associated passage/conduit. The device can be manually activated, but is designed so that thereafter it does not need to be manually held open. The consumer has time to leave the room before spraying begins, and does not need to be present in the room before spraying has finished.
