  • Patent number: 6141911
    Abstract: A pet door having a pair of bolt assemblies with bolts (28) mounted in a frame having an aperture (6) in which a door flap (18) is pivotably mounted. The bolts (28) are extendable into the door flap (18) and retractable into the frame (2) to lock and unlock the pet door, respectively. A bolt mechanism controller (50) is arranged to unlock the pet door on detection of a pet carrying the correct key transmitter (66) and to relock the pet door a user adjustable predetermined time after unlocking the pet door. This provides a pet door which can be used to automatically permit entry to a selected pet while using a robust bolt (28) of especial application to larger pet doors such as dog doors.

  • Patent number: 5701702
    Abstract: A pet door has a frame defining an access aperture with a pivotally-hung aperture-closing flap therein and with a catch to secure the flap against opening in one direction. The catch is supported on a collapsible support, and a pivoted lever is normally positioned to prevent collapse of the support whereby the catch is maintained in a flap-securing position. The lever bears a freely-rotatable elongate magnet which is co-operable with a key magnet on a pet collar, and when the key magnet is presented to the pet door, it attracts the magnet on the lever causing the lever to pivot to a position giving the support freedom to collapse and permitting the catch to be moved from the flap-securing position.

  • Patent number: 4447023
    Abstract: A helicopter (10) incorporates apparatus (15) for mounting a device such as an aerial or a sight (14) above a main sustaining rotor (13). The apparatus comprises first and second ring gears (16, 20) located respectively below and above the rotor, the first gear (16) being supported from helicopter structure (17) concentrically of an axis of rotation (11) of the sustaining rotor, support means (37) supporting the second gear and the device above the rotor in a manner permitting relative rotation of the rotor hub, and synchronizing means (25) rotationally fixed to the rotor hub and meshing with the first and second gears to retain the device stationary during rotation of the rotor system. In a preferred embodiment, positioning means are provided to rotate the first gear in either direction of rotation whereby the device can be rotated and selectively positioned independently of the rotation of the rotor.

  • Patent number: 4102423
    Abstract: A ground traction device is disclosed which comprises ground engaging members including first and second parts, the parts being mounted for rotation on a fixed axis and being rotationally offset with respect to each other about the axis. The peripheral surface of each part includes three individual areas arranged in the form of an equilateral triangle with ends of adjacent areas being joined by lobe portions. The ground engaging portions are constructed of molded rubber and provide improved traction in soft ground. The properties of the rubber are selected in relation to the weight of a vehicle to be moved so that the ground engaging member rotates about a true rolling radius over hard ground.
