Abstract: A jack apparatus for lifting an aircraft having landing gear including snow skis comprising a generally rectangular base having a first end, a second end opposite the first end, and at least two lateral members extending between the ends. The base is sized and shaped for positioning between the snow skis. The apparatus further includes a lift having a base end pivotally connected to the base adjacent its second end and a lifting end opposite the base end. The apparatus also includes a slide slidably connected to the base and a brace having an upper pivot end pivotally connected to the lift and a lower pivot end pivotally connected to the slide. In addition, the apparatus includes an actuator connected between the base and the slide for sliding the slide along the base.

Abstract: A snow ski tow bar adapts a prior art aircraft tow bar for attachment to a landing gear of an aircraft to which a snow ski has been attached. The snow ski tow bar modifies an existing tow bar with a second set of connectors that adapt the snow ski tow bar for connection to the landing gear of the aircraft having the snow ski. In addition, the existing wheels of the prior art tow bar are replaced with a second set of wheels that are spaced outwardly from the original wheels. This positions the second set of wheels on the snow ski tow bar where they are extended outside the lateral width of the snow ski on the landing gear. The second set of wheels support the tow bar in a position above the snow ski with the second set of tow bar connectors connected to the aircraft landing gear.

Abstract: Improved anti-pecking devices, particularly for poultry and game birds, comprise a pair of limbs having end portions of reduced cross section which engage the nostrils of the bird or other animal, at least one bit member connecting the limbs, and a guard member which projects forwardly from the limbs beyond the end of the beak of the bird. The forward end of the guard may be split. The device may further include resilient bias members which bear upon the upper surface of the beak, in use. Other variations include guard members which extend laterally outwards from the sides of the limbs and multiple bit members spaced apart along the length of the device. The size and configuration of the device and its constituent parts may be varied to suit different sizes and species of bird. The devices are configured to be stackable, such that they may be stored in a cartridge or magazine for application using an automated fitting device.
