  • RESPIRATOR MASK
    Publication number: 20230137526
    Abstract: Two-way filtering, non-valved, half-mask respirators are described in which a framework of polypropylene, or other relatively rigid, components provide structure and mounting points to the mask, thereby distributing mounting tension to a pliable inner seal. The rigid components also provide a hard port to allow for sealing pressure to receive a filter canister or container, while the pliable inner seal allows the mask to conform to the users face.

  • Vehicle coupling device
    Patent number: 8430419
    Abstract: A vehicle coupling device 10 for coupling a vehicle to another vehicle. The coupling device 10 comprises a mount 12 for mounting the coupling device 10 to the vehicle. The device 10 also comprises a first coupling 14 and a second coupling 16. Each of the first and second couplings 14, 16 is connected to a support 18 and movable relative to the mount 12 between an operative position and an inoperative position.

  • Dual-feedback amplifier circuit arrangements
    Patent number: 5684433
    Abstract: In an amplifier circuit arrangement in which series resistive feedback is utilized in the main amplifier to minimize distortion, and a feedback amplifier is provided in a path from the output of the arrangement to the series feedback path effectively to boost the value of the feedback resistor, a further amplifier is arranged to provide positive feedback to the resistive load circuit of the main amplifier effectively to boost the value of the resistive load.
