  • Patent number: 5699571
    Abstract: An infant bedding apparatus utilizes a mesh sleeping surface and a suspension device adapted to suspend the mesh sleeping surface above an existing sleeping surface of the bed thereby defining an air space between the existing sleeping surface and the mesh sleeping surface. The suspension device is a rigid rectangular frame having connectors, which may be elastomeric, for attachment to the mesh sleeping surface. Tensioners may be attached to the connectors for tensioning the mesh sleeping surface. As a result, the circulation of the fresh air in the area where body contact with the mesh sleeping surface occurs is improved when an infant is sleeping in a face-down or a substantially face-down position.

  • Patent number: 5462355
    Abstract: A paddle is used for mixing and cutting. A hub is at one end of the paddle for connecting the paddle to a planetary mixing machine. The paddle includes a plurality of interconnected arms in a fan-like array which define a plurality of slots between adjacent arms. The arms include a plurality of apertures formed therethrough. Outermost ones of the arms are positioned at opposite sides of the paddle. A plurality of wire members are secured at their opposite ends to the outermost arms. The wire members extend through the apertures formed in the arms and across the slots defined between the arms. The combination of the arms, the wire members extending through the apertures formed in the arms and across the slots defined between the arms, forms a plurality of multidirectional mixing and cutting components of the paddle. Cutting efficiency of the paddle relates to paddle size, mixing speed, mixture density, wire size, number of wires or distance of the wire members from the rotational axis of the paddle.
