Abstract:
A dry bin filling apparatus especially adapted for use in a packing house or like environment is disclosed and claimed. This dry bin filling apparatus includes an endless drive conveyor having an endless drive element and a plurality of filler cups attached to the drive element. At least some of the cups have flaps pivotally attached to the cups. The flaps are adapted to engage and slow the egress motion of objects coming out of other cups. Skirts can be pivotally attached to the flaps. The conveyor can be mounted on a support structure having the shape of a hockey stick so as to locate the depositing distal end of the conveyor closely adjacent to the bottom of a receiving bin or closely adjacent objects already placed in the bin.
Abstract:
The present invention relates to a locking mechanism and method of fixation, such a the fixation of a fixation device (104) like a bone screw and of a stabilization device (106 like a rod to the spine. The locking mechanism (100) includes a seat (102) and a locking element (108). The seat includes a bottom portion (114) configured to receive the fixation device (104) such that a socket (116) of the bottom portion (114) engages part of the fixation device (104) and prevents the fixation device (104) from passing entirely therethrough. The seat (106) further includes a side portion (112) configured to receive the stabilization device (106) and a locking element (108). The locking element (108), when fully engaged with the side portion (112) of the seat (102), causes locking of the relative positions of the fixation device (104) and the stabilization device (106).
Abstract:
A bone preparation device (2), comprises a guide body (30), a bone removal device (29) having a longitudinal axis extending between a proximal portion and a distal portion, a pair of guide members (34a,34b) movably engaged between said guide body (30) and said bone removal device (29), and an alignment device (100) movably engaged between said guide members (34a,34b). The bone removal device (2) may be movably guided by the guide members (34a,34b) and the alignment device (100) with respect to said guide body through a predetermined pattern.
Abstract:
An apparatus and method for positioning and controlling the movement of a bone removal device (10) and thus of controlling the profile of material removed by the device. Also an improved drive mechanism for a bone removal device, where the drive shaft (46) is readily removable for maintenance or replacement, without significant disassembly of the device.
Abstract:
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 (20, 40), 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.
Abstract:
A decelerator comprising a deceleration tank and an extraction conveyor is disclosed. The decelerator is adapted for use with apples or similar objects. These objects are delivered to the tank from a pneumatic tube transport system. The tank contains a quantity of liquid such as water. In one embodiment, the objects splash into the water and are extracted from the water by an extraction conveyor. In a second embodiment, a baffle gate divides the tank between a forward section and a rear section. The delivered objects splash into the water in the forward section, travel under the baffle gate, and are extracted from the water by an extraction conveyor in communication with the rear tank section. In another embodiment, the tank is divided into first, second and third sections by selectively appeasable gate which provides an air lock arrangement. The extraction conveyor can comprise a plurality of side belts and a plurality of foraminous, flexible cradles hung between the belts.
Abstract:
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.
Abstract:
An articulating intervertebral system for interposition between two vertebral endplates comprising: a first half (22) comprising upper and lower components (26,28) and a central body (38) adapted to articulate between the upper and lower components, and a second half (24) comprising upper and lower components and a central body adapted to articulate between the upper and lower components, wherein the first and second halves are adapted for implantation entirely within an intervertebral disc space between the two vertebral endplates .
Abstract:
Described is a locking mechanism and method of locking the relative positions of a fixation device (104) like a bone screw and of a stabilization device (106) like a rod. The locking mechanism includes a seat (102), a washer (108) and a cap (110). The seat (102) includes a bottom portion (114) configured to receive the fixation device (104) such that a socket (116) of the bottom portion (114) engages part of the fixation device (104) and prevents the fixation device (104) from passing entirely therethrough. The seat (102) further includes a side portion (112) configured to receive the stabilization device (106), a washer (108) and a cap (110). When the washer (108) and cap (110) are fully engaged with the seat (102), the fixation device (104) may be locked independent of the stabilization device (106). The locking mechanism may also include a locking element for locking the stabilization device (106).
Abstract:
An vertebral implant (20) is interposed between two vertebral endplates and comprises a first endplate assembly (22) having a first restraint mechanism extending from a first exterior surface (28) for engaging a first vertebral endplate The implant further comprises a second endplate assembly (24) having a second restraint mechanism (46) extending from a second exterior surface (30) for engaging a second vertebral endplate and a central body articulable between the first and second endplate assemblies. The first restraint mechanism has a shape that matches a contour in the first vertebral endplate.
