Abstract: An intraluminal prosthesis for intraluminal repair of body conduits, especially aortic aneurysms, is disclosed. The prosthesis includes a generally tubular, flexible graft (20) having a proximal open end (30) and at least one distal open end (31) terminating in a hem (33). A stent (21) can be disposed within the proximal open end (30) and is adapted to be attached to the body conduit (1). The hem (33) is inverted within the graft so that it is disposed as a cuff (34) within the graft. The hem (33) is arranged so that upon withdrawing the distal open end (31) from inside the cuff (34), the cuff will unfold and follow the distal open end to expose it to receive another stent for attachment to the body conduit (12) for intraluminal implantation of the graft.  Preferably the hem is folded a second time within the cuff to form a second cuff (35) within the graft. The stents are preferably formed of a plexus of wires adapted to expand from a first narrow diameter to a second diameter to engage the body conduit. Also disclosed is a method of intraluminal implantation of the graft.

Title: Stackable low depth bottle case
Inventor: KOEFELDA GERALD RALPH
IPC: A45F5/00
Filed: 1996-01-30
Abstract: A stackable case for retaining and transporting bottles including outer side walls (12, 14, 16, 18) forming an outer shell having a longitudinal axis and a horizontal axis, a case bottom (20) disposed substantially within the outer shell, and a plurality of supports for supporting the outer surfaces of the bottles. The side walls include a lower wall portion and a plurality of spaced upwardly projecting pylons, where four corner pylons define the four corners of the case. A plurality of spaced upwardly projecting columns (30) generally disposed within the outer shell define, in combination with the case bottom, the side walls and the end walls, a plurality of bottle retaining pockets. The columns and the pylons (58) extend above the lower wall portions and below a top surface of the retained bottles. The end walls each include an integrally molded handle structure (66) suspended between an upper portion of adjacent corner pylons to thereby define a generally open end wall area below the handle structure.

Patent CA-2213356-A1 (CA)
Title: Vacuum seed metering mechanism
Inventor: STUFFLEBEAM JOHN F
IPC: A01C7/04
Filed: 1997-08-19
Abstract: A suction-type seed metering apparatus operably arranged in combination with the seed storage hopper.  The seed metering apparatus comprises a disc vertically mounted with driven rotation about a fixed rotary path of movement and having a circular role of apertures adjacent to peripheral to disc.  A housing is arranged in seed receiving relation relative to the seed hopper.  The housing has its interior divided by the disc into two adjacent enclosures.  One enclosure at least partially defines a chamber for seeds and opens to the seed hopper.  The other enclosure extends at least partially around the path of movement of the disc apertures and constitutes a vacuum chamber having leading and trailing ends with an opening leading to the chamber intermediately leading and trailing ends.  The trailing end of the chamber is arranged adjacent to seed drop area from whence seeds gravitationally fall for deposit in a furrow.  A salient feature of the present invention concerns the provisions of a series of openings arranged proximate to the seed drop area for enhancing the release of seeds from the disc of the metering apparatus.  The openings defined in the housing of the seed metering mechanism allows atmospheric air to enter into the housing thereby eliminating the suction or draw of air through the housing.  Thus, the seeds are permitted to freely and gravitationally fall from the seed discharge area without being rearwardly drawn under the influence of a vacuum pressure.

Title: Fluid treating apparatus
Inventor: ASHBROOK CLIFFORD L
IPC: B01J19/24
Filed: 1995-07-25
Abstract: An apparatus (10) for treating fluids by increasing the fluid's rate of diffusion, removing minerals in solution, releasing entrained gases, and destroying bacteria includes a pair of cascaded vortex nozzles (26-29) positioned in opposed relation. Each of the vortex nozzles (26-29) communicates with a fluid source (14) to receive a fluid stream which it rotates. The cascaded vortex nozzles (26, 29) feed their rotating fluid stream into the rear of the vortex nozzle (27-28) with which they are cascaded. The rotating fluid streams fed into the vortex nozzles (26-29) combine with the rotating fluid stream within each nozzle. The combined streams then circularly rotate and exit the opposed vortex nozzles (27, 28) to collide in a chamber (30). The collision between the combined rotating streams results in the breaking of the bonds holding the fluid, gases, and minerals in their molecular array.
