  • Patent number: 5836114
    Abstract: Birds, especially, pigeons dislike the presence of a magnetic field because each bird has a biological instinctive ability of sensing the presence of the magnetic field. In order to utilize this biological instinctive sensing ability for the purpose of preventing birds from crowding at the upper part of a building, a plurality of magnetic members are disposed on an arm(s) turnably held at the uppermost end of a support column. When a bird perches on the arm, the latter is turned by the action of his own dead weight, resulting in the bird amazingly flying away from the arm. It is effective that a rotary wind blade having two magnetic members immovably secured to the opposite sides thereof is disposed at the uppermost end of each support column so as to largely affect the magnetic field induced by the magnetic members disposed on the arm and the magnetic members disposed on the rotary wind blade.

    Abstract: A magnetic gripper provides a support for releasable attachment to a ferromagnetic surface. A magnet adheres the gripper to the ferromagnetic surface. A frame is rotatably attached to the magnet where the frame defines cam surfaces to raise and lower the magnet from the ferromagnetic surface. An ear extends from the magnet to engage the ferromagnetic surface at a location spaced from the cam surfaces so that an end of the magnet near the ear can be first disengaged from the ferromagnetic surface, causing an air gap between the magnet and the ferromagnetic surface. The remainder of the magnet is sequentially disengaged from the surface as the cam surface is rotated. A foot support may be rotatably mounted to the frame so that a user can stand on the gripper to perform maintenance and repairs on the structure defined by the ferromagnetic surface.

  • Patent number: 4486995
    Abstract: An insulating panel which comprises at least one layer of polystyrene covered on at least one side by a layer of cellulose. Preferably, the cellulose is intermixed with an adhesive and sprayed onto the polystyrene and the adhesive, and upon curing, bonds the cellulose together and to the polystyrene layer; or, alternatively, the cellulose material is molded into a pad or panel which is subsequently bonded to the polystyrene layer. The exposed side of the cellulose layer is in turn covered with a vinyl or other decorative coating to form the insulating panel. The overall insulating panel exhibits a very high R value and thus has a very low coefficient of thermal conductivity.
