Abstract: A cutting apparatus for cutting corner pieces formed of stone or other materials for use as building faces or for cutting flat pieces is disclosed herein. The cutting apparatus includes a frame with a first and a second conveyor operatively attached to the frame. The first and the second conveyors are configured to carry a workpiece from a first end of the frame to the second end of the frame. The first conveyor is disposed at an angle of about 45 degrees to a ground surface supporting the cutting apparatus. The second conveyor is disposed at an angle of about 45 degrees to the ground surface supporting the cutting apparatus, wherein the second conveyor is positioned perpendicularly to the first conveyor so as to form a V-shaped channel therewith.

Abstract: An ankle block for a leg prosthesis comprising an insert having a body with an upper mounting surface and a bottom interface surface opposite from the upper mounting surface. The insert body defines a central coaxial hole therethrough. An over mold is formed about an exterior of the body and extends upwardly therefrom defining a central cavity above the insert and above the upper mounting surface.

Abstract: A thin stone cutting apparatus and method includes a groove cutting device for cutting a groove in a side of a block of stone along a first cutting plane. A block cutting device cuts each block of stone in a direction from an opposite side of the block. A block cutting device cuts each block along a second cutting plane co-planar with the first cutting plane. Alternatively, the first and second cutting planes of the groove cutting device and the block cutting device can be at different angles to one another. A block holder device includes a linear member received in a groove of each block when each block is being cut by the block cutting device. A conveyor is provided for moving each block relative to the block cutting device where the linear member of the block holder device is mounted to the conveyor. Alternatively, the block cutting device is moveable relative to the block holder device. The resulting stone includes a rock body made from natural stone and having a front, and an opposite facing back.

Abstract: A prosthetic foot gasket for sealing between a foot shell covering a foot portion of an endoskeletal prosthetic leg and a leg portion thereof comprises a peripheral body having an upper surface and further defining a central opening therethrough. A lip extends from a bottom of the body and in combination with the body defines a groove therearound for receiving a top portion of the foot shell. A seal is affixed to an upper surface of the body for sealing engagement with the leg portion of the prosthetic leg.

Abstract: The present invention is footwear for use by an able-bodied person to test and appreciate the functions of a prosthetic foot. The footwear includes an upper for attachment to a user's foot and a mounting plate attached to the inside sole of the footwear. An adapter is mounted to the mounting plate for receipt of the foot prosthesis. The adapter allows for adjustment of the prosthesis with respect to the footwear.

Abstract: A prosthetic foot assembly, said assembly includes an ankle member, a heel member pivotally connected to the ankle member, an elongate metatarsal-toe member having a rear portion underlying a forward portion of the heel member and projecting forwardly from the heel member. The metatarsal-toe member being pivotally connected to the heel member. A first compressible element is engaged between a portion of the ankle member and a portion of the heel member and a second compressible element having first and second substantially circular bearing surfaces engaged between a portion of the heel member and a portion of the metatarsal-toe member to resist upward pivotal movement of a forward end of the metatarsal-toe member relative to the heel member. A portion of the compressible element spaced apart from one of the bearing surfaces has a smaller diameter than the diameter of at least one of the first and second bearing surfaces.

Abstract: An automated stoneworking system and method for cutting and shaping various stone materials, such as marble and granite, in any number of preprogrammed fashions so as to eliminate the need for manual stoneworking operations.

Abstract: A prosthetic foot includes an ankle member, a heel member and a toe member coupled to each other for relative pivotable movement with the pivotable movement resisted by elastomeric pads. The heel and ankle member are connected through a joint allowing for translational and pivotable torsional motion of the ankle with respect to the heel and provided with limit stops in the axle and the side walls of the heel member to limit the torsional and translation motion of the ankle joint. The toe member is formed symmetrically to be used for left and right feet with symmetrically positioned and mirror imaged fore sections.
