The present invention concerns to a total knee prosthesis including a femoral implant having an anterior wall that forms the upper portion of a prosthetic trochlea and two curved branches extending from the lower edge of said anterior wall, delimiting the lower portion of the prosthetic trochlea between them and forming condylar surfaces between them. The trochlea has a middle furrow bordered by two rounded convex surfaces. The trochlea has in its upper portion a flexion of approximately 50°. The trochlea has a depth smaller than the height of the longitudinal middle rib comprised by the patella and has a width larger than that of that same rib, such that the patella comes into contact with the femoral implant essentially by that rib and said concave side faces are situated at a distance from said rounded convex surfaces. In the lower portion, the trochlea has a depth greater than the height of said rib and has a width substantially equal to that of said same rib, such that the patella comes into contact with the femoral implant essentially by said concave side faces, and said rib is at a distance from the bottom of the trochlea.

An inventive apparatus and method provides for restricting movement from a collapsed or folded position of a pair of rails employed by a shoring assembly. The shoring assembly has a plurality of first pads each pivotally connected to one of the rails, a plurality of second pads each pivotally connected to the other of the rails, and a plurality of hydraulic jacks each being operatively connected between an opposing pair of the first and second pads. The pivoting movement of the plurality of first pads is restricted relative to the one rail when the rails are disposed in the collapsed position. In a particular embodiment, a pair of first pads and a pair of second pads—respectively known as cylinder pads and socket pads—are employed by the shoring assembly. Accordingly, a pair of hydraulic jacks are further employed in this embodiment of the shoring assembly.

A slag transport and dumping apparatus, for use with slag, includes a vehicle, a pallet, and a lifting mechanism. The vehicle includes a bed having a pallet interface. The pallet includes a support frame having ground support members, and a transporter interface selectively engaging the pallet interface. A dump container has a slag reservoir.

In a transporting configuration, the container is in the retaining configuration, and the vehicle securely engages the pallet, in carrying relation, thus enabling transport of the pallet.

Closer arm assembly includes a main arm having a first end fixed to the output shaft of a closer fixed to one of a door and a door jamb so that the main arm pivots when the output shaft rotates, and a connecting arm having a first end pivotably connected to the main arm and a second end connected to the other of the door and the door jamb. The connecting arm contacts a stop to limit relative pivoting of the arms, the stop including a cushion with a contact surface which suppresses noise as the connecting arm contacts the cushion. The stop can be in the form of a spring loaded bumper fixed to a soffit plate, or a pin fixed to the second end of the main arm. A hold open device can be fixed to the connecting arm for engaging a feature on either the soffit plate or the main arm, the hold open device having a spring loaded detent which is released by manually turning a knob.

A closure panel assembly includes a movable or “sliding” panel that is supported for sliding movement along a first direction by a guide rail disposed above an opening defined in a stationary or “fixed” panel. The guide rail includes an engagement portion that overhangs an upper portion of one face of the sliding panel. The overhanging engagement portion of the guide rail limits the relative movement of the upper portion of the sliding panel in a second direction perpendicular to the first direction, while further limiting a pivoting motion of the lower portion of the sliding panel in the second direction. A latch is operative to urge the lower portion of the sliding panel towards the fixed panel, whereupon the sliding panel pivots proximate to the guide rail into a closed position while also compressing a seal disposed between the sliding panel and the fixed panel.
