  • Publication number: 20080184625
    Abstract: Described is an animal door for providing an animal a passageway through a structure and for reducing thermal transfer through the passageway. The animal door defines the passageway, which is sufficiently large for the animal to pass through, and is adapted to be secured to the structure such that the animal can pass through the structure by passing through the passageway. The animal door includes at least three flaps disposed at the passageway. The flaps are constructed and configured to reduce thermal transfer through the passageway by reducing both thermal convection and thermal conductivity at the passageway.

  • Patent number: 4566049
    Abstract: A method and an apparatus for indexing a transducer head, such as is used in magnetic tape recording, is disclosed. A transducer head is mounted on a head carrier. The carrier supports a cam follower and the carrier and cam follower are resiliently biased against a cam. A gear train, including both a motor and the above-mentioned cam are mounted on a common support device. The support device is pivotally mounted. The head can consequently be initially indexed to a given track on the tape by pivoting the support device; this has the effect of moving the entire cam up and down and consequently the head as well. Once the head has been indexed to a given track it is moved between the various tracks by rotating the cam via the gear train.
