A spinal plate assembly comprising a base plate defining an opening adjacent at least one aperture for receiving a bone screw which attaches to a spinal vertebrae. The aperture includes a seat and an annular groove having an end wall. The assembly comprises a locking mechanism having a split ring partially recessed within the annular groove and moveable between a locked condition partially blocking the aperture for retaining the screw in the seat and an unlocked condition radially deformable into the annular groove for permitting screw removal. The split ring has a proximal end and a distal end. The distal end is configured to engage the end wall of the annular groove. The locking mechanism comprises a rotating member retained within the opening of the base plate and having a notch configured to engage the proximal end of the ring to drive the ring toward the unlocked condition.

A tool for removing an object from a hole in a workpiece which includes a first and second arm pivotably connected together. Each arm having an opening between the ends. The second arm also has a drill hole at the second end. A liner bushing and a drill bushing can be provided in the drill hole. To remove the object from the workpiece, the drill hole is positioned over the object and the arms are adjusted until at least one (1) of the openings of one of the arms is positioned over an existing hole in the workpiece. A securing bolt is then inserted through the opening in the arm into the hole in the workpiece and tightened to secure the tool to the workpiece. Next, a drill bit is positioned in the opening of the drill bushing adjacent the object and rotated until the drill bit is completely through the object.

An improved MIG welding pliers is disclosed, which allows faster and easier removal of spatter form a MIG welding nozzle, thereby improving welder productivity. Embodiments of the present invention provide a rounded file on the outer surface of each of the pinchers of the pliers. In one embodiment, each pincher has a different file surface. The rounded file surface provides for improved spatter removal, and eliminates the need for waxes and spatter control products which degrade the contact tip and nozzle, hastening the need for their replacement. Therefore, embodiments of the present invention increase the efficiency of a MIG welding operation, as less time is spent removing spatter from nozzles, and thus, more time is available for welding. Furthermore, by avoiding the use of waxes, costs are reduced since nozzles and contact tips do not need to be replaced as frequently.

In particular, a trash compaction device which can be used on-board aircraft, trains, ships and / or for civil applications and generally in all the locations and / or transportation means where the auxiliary service equipment must occupy as little space as possible. The compaction device is formed by a system of hollow telescopic screws (5,6), for example of the recirculating ball type, operated by a motor (2) housed inside the said screws (5,6). The compactor may be conveniently installed in compartments, which are fixed or movable on wheels, such as a trolley, so as to allow easy displacement thereof within the transportation means and insertion within the appropriate working spaces.

A self-contained, low-maintenance planter assembly used indoors or outdoors to provide prolonged self-watering of plants in a tray preferably supported by an easily height-adjustable frame insert positioned within the lower reservoir portion of a fluid-containing planter housing. Interior tray-lifting members are located adjacent to the tray's top edge, and the tray's bottom surface has perforations. Plant roots may be in growth / support medium distributed directly into the tray, or in drainable pots. Fluid-permeable material under the growth / support medium allows surplus rainwater to refill the planter housing via the tray's perforations in outdoor applications, while an overfill prevention hole in the planter housing prevents nutrient / liquid therein from entering the tray, with wicking member or members instead distributing nutrient / liquid upwardly to tray-supported plant roots. No tools or power / water connections are needed for assembly function. Applications include, but are not limited to, residential and commercial use, including hotels, convention centers, malls, and schools.

An upper denture release apparatus and method of use. A denture puller has a chin rest, arm attached to the chin rest, and a hook attached to an end of the arm opposite the chin rest. An upper denture has a notch sized and located to admit the hook when a wearer's chin rests on the chin rest. The method includes the steps of resting a wearer's chin on the chin rest, inserting the hook into the upper denture notch, and opening the wearer's mouth, thus pulling the upper denture off the wearer's upper gum. Arm length adjustment is shown, whereby the denture puller may be adjusted to fit differently-sized upper denture wearers. Preferred hook declination, hook toe, arm and notch floor angles are disclosed.
