  • Patent number: 10634250
    Abstract: A non-collapsible flexible sealing membrane (or bellows) for incorporation in a mechanical seal assembly and use in rotary shaft equipment. The sealing membrane includes a substantially radially outward extending first flange portion, which can be urged into an axially shiftable ring by a biasing mechanism. The sealing membrane further includes a substantially axially outboard extending second coaxial portion, substantially radially inward of the balance diameter of the seal. The horizontal portion is advantageously held fixed to a stub sleeve by an annular band. The angle between the vertical portion and the horizontal portion of sealing membrane enables directional control of the forces acting on stub sleeve and primary ring.

  • Publication number: 20080035589
    Abstract: A slidable pull-out tray for displaying merchandise in a very neat and attractive manner while making it very easy for the customers to remove a package from the display and very easy for the store proprietor to restock the merchandise. In one embodiment, the trays are self supported by cantilever brackets attached to a gondola bracket fixture. No shelves are required, thereby maximizing the total amount of goods that can be stocked within a given vertical height. In one embodiment, the floor of each tray is an open grid thereby greatly facilitating cleaning of the fixtures. Pusher paddle assemblies engage the open grid and slide along bars forming the grid.
