  • Patent number: 4594966
    Abstract: A device for controlling the movement of an animal is provided which includes a cone-shaped covering (10) for the animal's head. The covering (10) is made from a collapsible, light-impermeable, durable material. A closed end (11) is constructed to prevent suffocation of the animal when the covering is placed on the animal's head for a relatively short period of time. A rigid member (14) is provided at an open end (12) of the covering (10) to support the end (12) in an open state allowing the animal's head to enter the covering interior and to provide a collar about the shoulders of the animal whereby pressure may be exerted upon the animal to direct the movement of the animal while confined in the covering. A handle or hand hold area (15) is provided so that the user may securely grasp the rigid member (14) to manipulate the device.

  • Patent number: 4537574
    Abstract: A method and apparatus for performing prosthodontic work comprises a face bow formed from a plate which supports impression styli which, when removed from the patient's head, is incorporated as the upper arm of the dental articulator. At least one, but preferably two, impression receptacles containing impressionable material are detachably secured to a lower face bow in registration with the stylus on the upper face bow to form the impression. Each receptacle is removed from the lower face bow after age hardening of the impression, and is secured to an articulator base at a position which maintains registration between the stylus and the impression formed in the receptacle. The impression formed thus forms a condylar guide hinge for mounting the upper arm of the articulator, preferably the upper face bow to the base, for simulating the condylar movement of a particular patient with respect to dental impressions to be used in forming dental prostheses to be worn by the patient.

  • Patent number: 4531346
    Abstract: A stirrup stay for adjusting the horizontal angle of a horse saddle stirrup is constructed from a strip of sheet material that is adapted to be received in the space between the inner and outer portions of a stirrup strap and resting in the loop at the bottom of the strap. The strip of sheet material is hand-deformable by twisting to selectively impart the desired degree of twist to the stirrup strap. The strip may be formed from sheet metal having a cushioning coating protecting a majority of the edges. In one embodiment, a sheet metal strip is bent by 180 degrees near its center to bring opposite longitudinal ends together, and the opposite halves of the strip are covered by a sheath of leather, rubber, or other yieldable material. A central portion of the strip near the bend may remain uncovered and is protected, in use, by placement of the stirrup with its pivot pin resting in the bend.

  • Patent number: 4531477
    Abstract: The invention comprises a generally rectangular plate and a mounting system so that the plate can be mounted adjacent to and parallel to one wall of a fish containing enclosure, such as an aquarium. An elongated nozzle and water conduit are attached to one edge of the plate. In use, the nozzle directs a curtain of water transversely across the plate within the volume defined by the plate and enclosure wall. Fish are generally attracted to this faster moving water and preferentially move into the volume between the plate and enclosure wall. In an aquarium, this places them in a close up position where they can be easily watched by an observer.
