  • Patent number: 4604996
    Abstract: An external skeletal fixator for treating an injured mammalian limb, such as a horse's foreleg, includes a plurality of transfixation pins which transfix the bone at separated sites along the limb proximal the injury and terminate beyond the limb; means, exemplified by an organic polymer, for rigidly connecting pin terminii to a weight bearing member carried beneath the foot of the limb; together with means, e.g., affixing said weight bearing member to the foot of the limb, for immobilizing the limb distal the injury, whereby the weight of the mammal is transferred from the limb proximal the injury to the weight bearing member, permitting the mammal to ambulate while the injury heals.

  • Patent number: 4438579
    Abstract: A kit for making a three-dimensional picture includes a frame encircling a three-dimensional window into which may be inserted a plurality of substantially planar decorated scenes. The depth of a scene in the window in determined by bending backward resilient hinges carried at the edges of the scene. The scenes are removably anchored in the window by frictional engagement between the hinges and the inner sides of the frame. Cut out regions in the scenes permit more remote scenes to be viewed, creating a three-dimensional effect. Including replicas of scenes allows more than one picture to be created with the kit.
