  • Patent number: 7523890
    Abstract: A method of severing an extraction line connected between an extraction parachute and a cargo load when the cargo load fails to eject from an aircraft. The method comprises the steps of spacing a cutter from the extraction line; spring-biasing the cutter in the direction of the extraction line; mechanically restricting the cutter with restricting means from engaging and severing the extraction line; and disabling the restricting means in response to a radio signal from a transmitter on the aircraft so that the cutter is released and severs the extraction line.

  • Patent number: 7306188
    Abstract: A device for severing an extraction line connected between a cargo load and an extraction parachute when the cargo load fails to eject from an aircraft. The device comprises a cutter spaced from and spring-biased in the direction of the extraction line; a housing for the cutter; elements for mechanically restricting the cutter from engaging and severing the extraction line; and elements responsive to a radio signal from a transmitter on the aircraft for disabling the restricting means so that the cutter is released and severs the extraction line.

  • Patent number: 4567905
    Abstract: A slideable control is provided for use in retractable bristle brushes. It operates by co-action with a rotatable, cylindrical mandrel carrying pivoted bristles and having an angular cam slot. The control includes a longitudinally slideable button in the handle which has a control pin operatively extending through a control slot in the handle and then into the cam slot to cause rotation of the mandrel. The angular cam slot includes an axial portion at each end to receive the control pin and to lock the mandrel in a position with the bristles either fully retracted or fully extended. The control button includes a pair of parallel guide blades, one on each side of the control pin, slideable within slotted guides in the handle, to reduce torque between the control pin and the cam slot. The control slot may include detents proximate to its ends to receive and hold the control pin against longitudinal movement.

  • Patent number: 4285813
    Abstract: Aquarium filtration apparatus having a generally trough-shaped filter housing, the rear wall having a bracket portion for hanging on an aquarium, an impeller assembly having a drive magnet being positioned within the bottom of the filter housing with a motor assembly coupled to the undersurface of the bottom with a power driven magnet on the motor assembly in spaced proximate relation to effect magnetic coupling with the magnet of the impeller assembly. An intake assembly is provided in fluid communication with the impeller assembly and with the aquarium water for drawing water from the aquarium into the filter housing. In a first embodiment, the intake assembly is an intake tube having a portion within the filter housing. In a second embodiment, the intake assembly includes a filter chamber within the filter housing in fluid communication with the impeller assembly with an intake tube coupled to the filter chamber for drawing water from the aquarium into the chamber.

  • Patent number: 4147133
    Abstract: A dispenser for small animal food or the like, the dispenser including a base member having a planar surface and upwardly extending wall portion defining an elongate trough for tiltably receiving a plurality of unitary hopper members, each hopper member having a front wall, sidewalls, a back wall and a bottom with a pivot projection downwardly depending from the bottom, the pivot projection being generally coextensive or co-planar with the front wall. A depressor pedal member is generally co-planar with the bottom and is supported in generally parallel relation with the planar surface of the base with the hopper member supported within the trough. A cover is provided to completely enclose the plurality of hopper members, the cover having an aperture through which the depressor member extends, the cover aperture being in alignment with a hopper aperture formed in the front wall.
