Abstract: Kits for building log structures, and methods for producing such kits. A kit for building a structure having a plurality of log walls each including multiple layers. The kit comprises a combination of logs which when assembled form the structure. Logs of multiple layers are marked for long groove cuts and for final corner notch cuts. These marked logs substantially retain the natural contour of the tree boles from which they came. In other embodiments, final corner notches have been cut in logs of multiple layers and long groove cuts are marked but uncut. In still other embodiments, long grooves have been cut in logs of multiple layers and final corner cuts are marked but uncut. Certain embodiments provide kits wherein logs of multiple layers each have cut therein at least one final corner notch or long groove, with the remaining cut(s) marked but uncut.

Abstract: A method is provided for building a log structure using naturally-shaped logs. Kits for building log structures are also provided as are methods for producing such kits. In certain embodiments, there is provided a kit for building a structure having a plurality of log walls each including a plurality of log layers. The kit comprises a combination of logs which when assembled form said structure. Logs of a plurality of the log layers are marked for desired long groove cuts and for desired final corner notch cuts. In the present embodiments, these marked logs substantially retain the natural contour of the tree boles from which they came. In other embodiments, final corner notches have been cut in logs of a plurality of the log layers and desired long groove cuts are marked but uncut on these logs. In still other embodiments, long grooves have been cut in logs of a plurality of the layers and desired final corner cuts are marked but uncut on these logs.

Abstract: A method of building a log structure using naturally-shaped logs is provided. The method involves stacking layers of the log structure upon one another in a rough approximation of the final desired positioning, determining the distance of the greatest gap existing between the pairs of logs at each layer, determining groove cuts to be made for every log in the same layer using the same vertical groove dimension, determining a dimension of a final notch cut to be made in the logs of the lowest layer stacked according to this invention, and determining the final notch cuts to be made at layers above according to a relationship among the vertical groove dimensions that were marked for each of the grooves in a single layer and the dimension of the final notch cut determined for the lowest layer of logs stacked according to the present invention.

Abstract: The present invention relates to a method and apparatus for moving sheets from substrates without substantially moving the substrate and, specifically, where the sheets are sheets of X-ray film and the substrates are screens found in conventional X-ray cassettes or other sheets in a closely packed stack of sheets. The method and apparatus use at least one suction cup for curling and, thereby, lifting a portion of a sheet near an edge thereof allowing air to partially enter underneath the sheet. The suction cup has a sheet contacting face with a recess extending into the face where the recess is defined by an inner conical surface, a first planar surface and a second planar surface.

Abstract: A pallet is releasably attached to a car which is stopped automatically at a work station in a coarse alignment with a robotic system at the work station. A movable plate, which tends to be distorted from a given shape, is releasably secured to the car and lifted from the car at the work station, aligned in the desired fine alignment during the lifting and then clamped in place relative to a reference plane in the fine alignment relative to the robotic system to remove the distortion. The plate is later dropped by gravity onto the car in a given alignment therewith for transfer to the next work station which repeats the fine alignment and distortion removal action.

Abstract: A face guard for an athletic helmet having at least one horizontal bar structure with the bar structure including a plurality of rotatable elements to inhibit gripping the bar structure by hand.

Abstract: A television receiver is located on a pallet assembly via molded-in-place locating elements in the receiver base. Two elements have corresponding openings which mate with respective resilient structures on the pallet assembly to locate the receiver in two orthogonal horizontal directions about a vertical axis. A set of the elements on the receiver base abut a set of corresponding elements on the pallet assembly for positioning a plurality of spaced points on the receiver cabinet in the vertical direction in a reference horizontal plane.

Abstract: A molding apparatus for molding a recorded disc includes a pair of mold plates adapted to form a mold cavity therein and a center hole forming pin slidably mounted in one of the mold plates. The center hole forming pin is larger in diameter than the hole to be formed and has a projection on its end which is of a diameter equal to the hole to be formed and a length about one-half the length of the hole to be formed. The other mold plate includes a projection extending therefrom of a diameter equal to the diameter of the hole to be formed and a length one-half the length of the hole. In the molding of the disc the projection on the center hole forming pin engages the projection on the other mold plate to form a hole in which a flash is spaced from the edges of the hole.

Abstract: The flash is removed from a freshly molded recorded disc by first bringing a knife against the edge of the disc and rotating the disc about its center to remove the major portion of the flash. A rotary cutter is then brought into contact with the edge of the rotating disc to remove the remaining portion of the flash. The rotary cutter provides the disc with a smooth edge and allows an accurate control of the diameter of the disc. The cutter is mounted on a pivotal bracket which is selectively moved toward and away from the disc by means of an air cylinder and piston which is connected to the bracket.
