  • Patent number: 5373814
    Abstract: The preferred embodiment of an animal restraining device has a plurality of flexible elongated members attached at one end to a snap hook, with the opposing ends attached to suction cups. This allows an animal, such as a dog or cat, to be restrained at any suitable surface capable of supporting a partial vacuum suction cup attachment. The animal is restrained by connecting a snap hook to the animal's collar, and the suction cups at the surface. By making the elongated members from elastomeric material, a non-jerking increasing restraining force is generated as the animal tries to move away, and the animal is soon taught to remain at a desired location. The invention eliminates required adjustment means and rigid framework of the prior art, thus providing a simpler device to manufacture while also allowing an animal to be restrained in a more natural and comfortable position.

  • Patent number: 4807748
    Abstract: An attachable riser used in material handling is held in place by spring clips. At least two such risers are attached to the underside of an object allowing clearance for the forks of a machine such as a forktruck to move under the object. When the object is picked up, moved, and set down the risers remain attached to the object thus eliminating the manual moving or placement of ordinary risers such as timbers. The risers are easily removed from the object when desired.

  • Patent number: 4777874
    Abstract: A container used for compacting materials such as low level radioactive waste has a device used to keep the compacted material from springing out of the container when the compacting force is removed, thus resulting in a significant increase in the final compacted density. The device develops its restraining force by using the beam strength of its members. The device includes a louvre attached to the container, enabling the cross beams to be snapped into place with a wedge shape of the cross beam end or a hydraulic clamping device external to the container.
