  • Patent number: 5558499
    Abstract: According to this invention, there is provided a centrifugal blower wheel with backward curved comprising a disk, a shroud and a plurality of airfoil shaped blades. By separating the blades into "vane members" which assume the function of a fluid device and "vane attachment members" which assume the function of a rotating device, there is a greater degree of freedom of design, so optimum materials and shapes can be assigned to these different functions. The disk, the shroud and the vane attachment members are therefore constructed of metal and provided with beads so as to give a highly rigid structure, while the vane members are constructed of non-metal. This makes it possible to provide a blower wheel which is more lightweight and quieter in operation than a conventional blower wheel.

  • Patent number: 5375357
    Abstract: A ticket mounting apparatus which includes a bracket for attaching the ticket support to a shelf or the like. The mounting apparatus includes a structure to permit the label to be mounted in several selected positions. The mounting apparatus is made up of a C-shaped outer member having internal teeth and a slot. A cylindrical C-shaped inner member having external teeth is received in the C-shaped member and a bracket attached to the C-shaped inner member and extends through the slot and can be attached to a bracket holder. The C-shaped outer member can be attached to a support and the bracket can extend out of the slot so that the ticket holder can be swung up and down with the cylindrical member.
