20100070042 | Implantable Joint Prosthesis - The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable. Desirably, the outer surfaces of the shells are adapted to allow for bony ingrowth, which further stabilizes the shells in place. The inner surfaces of the shells are relatively smooth, and adapted to slide easily across a portion of the outer surface of a central body disposed between the shells. The central body has a shape that cooperates with the shape of the inner surface of the shell so as to provide a range of motion similar to that provided by a healthy joint. A flexible sheath extends between edges of the opposing shells. The inner surface of this sheath, together with the inner surfaces of the rigid shells, defines a cavity encasing the central body. At least a portion of this cavity is filled with a fluid lubricant, further decreasing the frictional force between inner surfaces of the shell and the surface of the central body. | 03-18-2010 |
20110091292 | TRANSPORT SYSTEM FOR FRUIT AND LIKE OBJECTS - A device for transporting articles is disclosed. In the illustrated and described embodiment of the invention, the articles are fruit such as apples, and the articles can be transported from a picking location on a fruit tree to a collection bin or other site. The device includes a tube member adapted to receive and transport the articles, and a plurality of deformable baffles at spaced-apart locations within the tube. Each baffle defines an aperture which permits the article to engage and deform the baffle and aperture so as to create at least a partial momentary seal to encourage article movement through the aperture and down the tube. The article is urged through the tube by a pressure differential created across the article. In the described and illustrated embodiment of the invention, this pressure differential is a pneumatic pressure differential. The tube and the baffle apertures can have non-circular cross-sectional shapes. | 04-21-2011 |

20130064611 | DRY DECELERATOR FOR APPLES OR LIKE OBJECTS - A decelerator device for apples or the like is disclosed. The apples are delivered to the decelerator device by a tube which can be provided with either a positive pressure upstream of the transported objects or a downstream of the transporter device. In one embodiment of the invention, the decelerator is provided with an area of reduced pressure in communication with the distal end of the transport tube. A receiving device such as a plurality of inter-engaged wheels receives the apples of other objects in the area of reduced pressure. The wheels or conveyors receive objects between opposed sealing surfaces, reduce the traveling speed of the object, and transport the object to an area of ambient pressure. The sealing surfaces are disengaged from the transported objects in the area of ambient pressure, and the objects are delivered to a transport path, dry bin, or other desired structure. In another embodiment of the invention, a counter flow of air reduces the speed of the object traveling along the tube. | 03-14-2013 |

20080264030 | STEM CLIPPER AND CRUSHER MECHANISMS FOR USE WITH FRUIT TREES AND THE LIKE - A clipper or shearing mechanism for separating a produce item such as an apple from the plant upon which it has grown such as an apple tree is disclosed. The mechanism provides a stem separating or severing mechanism comprising at least two mutually movable elements adapted to engage and sever the stem of the produce item. A trigger can be provided to actuate the stem severing mechanism. If desired, a mounting mechanism for mounting the severing elements in a predetermined position relative to a produce intake element can be provided as well. The mechanism can also be provided with crushing mechanisms to crush and soften an exposed portion of the produce item stem. The crushed stem will be less likely to poke and consequently damage adjacent produce items. | 10-30-2008 |

The article is urged through the tube by a pressure differential created across the article. In the described and illustrated embodiment of the invention, this pressure differential is a pneumatic pressure differential. | 11-13-2008 |
20100037583 | MOBILE SYSTEM FOR IMPROVING THE PICKING AND PRELIMINARY PROCESSING OF APPLES, CITRUS, STONE FRUIT AND LIKE OBJECTS - A mobile system for improving the picking and preliminary processing of apples, citrus, stone fruit and the like is disclosed and claimed. The system comprises a mobile chassis upon which can be mounted picking stations, pneumatic tube transport subsystems, receiving and conveying subsystems, object scanning subsystems, cull diverter subsystems, labeling subsystems, and subsystems for relatively gently placing the objects in a predetermined location in a receiving bin. The system can also include a subsystem for gently placing diverted objects in a receiving bin. | 02-18-2010 |
20100230244 | DOWNLOADER CONVEYOR FOR APPLES AND LIKE OBJECTS - A downloader conveyor is described and claimed. The downloader conveyor comprises an endless belt to which a plurality of cups is pivotally attached. The cups are adapted to receive apples or like relatively delicate objects. As the cups containing the apples descend into the bin, the cups rotate so as to permit the apples or other objects to roll out of or exit from the cups and to retard the cup acceleration. Each apple engages a skirt, which breaks the fall of the exiting apple. A distal end of the skirt can be arranged to scrape over the bin floor or scrape over the top of apples or other objects already placed in the bin, so as to again break the fall of the apple so that the apple is placed in the bin without substantial freefall. | 09-16-2010 |
