摘要： Methods and apparatus for reducing surface discontinuities, resulting from the formation of a three-dimensional object out of a plurality of stacked layers, during layer by layer stereolithographic formation of the three-dimensional object. The discontinuities between layers are reduced by utilizing formation and solidification of thin fill layers near the edges of thicker structural layers or by utilizing surface tension effects to smooth discontinuities between the structural layers by formation of meniscuses of building material and solidifying the meniscuses.

摘要： A shock-absorbing telescoping tool handle is disclosed having a larger diameter proximal portion and a smaller diameter distal portion. An internal spring in the handle portions is compressed when the handle portions telescope towards each other upon shock being applied to the tool handle. Guide mechanisms in the handle portion limit the extent of sliding motion between the handle portion and prevent relative motion of the handle portions. One or more wipers in the handle portion wipes away any snow, water or debris on the distal portion which could potentially enter the spring area. The spring may be located within the proximal portion or the distal portion of the tool handle.

摘要： A shock-absorbing telescoping tool handle is disclosed having tubular, larger diameter proximal and a smaller diameter distal portions. An internal spring between the handle portions is compressed when the handle portions telescope toward each other. Guide mechanism in the handle portions limits the extent of sliding motion between the handle portions and prevents relative rotation of the handle portions. One or more wipers in the handle portion wipes away any snow, water or debris on the distal portion which could potentially enter the spring area.

摘要： A thin relatively stiff but somewhat resilient sheet of plastic material is formed into a series of aligned, identically-shaped and dimensioned cavities for holding thin-walled plastic flower pots with the cavities having ribs formed on their inside surfaces and hand-access cutouts in their side walls. As an added feature, a skirt or flange for lifting and carrying the tray is provided and suitable drain holes may also be provided.
