Abstract: A method for forming a tubular construction element built up of longitudinally extending segments joined together in a side-by-side relationship, wherein the length in the longitudinal direction of the tubular construction element is greater than the diameter thereof.

Abstract: Compliant manipulators are provided, in which the manipulators include a plurality of slideably interlocked filaments each having a proximate end and a distal end. The interlocked filaments can be formed from a flexible material. The compliant manipulators can also include at least one filament-actuating device operatively connected to the respective distal ends of the plurality of slideably interlocked filaments. The at least one filament-actuating device can be manipulated directly or remotely to push and/or pull the respective filaments to impart a desired movement to the manipulator. The stiffness or flexibility of the manipulators can also be controlled to provide varying degrees of stiffness during use.

Abstract: An apparatus for reducing propagation of cracks in concrete includes a curved panel. The curved panel includes a convex surface and a concave surface facing away from one another and separated by a thickness. Each of the convex and concave surfaces has a top edge, a bottom edge, a first end, and a second end. Each of the convex and concave surfaces is configured to be arranged in direct contact with the concrete. The curved panel further includes a top surface extending between the top edges of the convex and concave surfaces. The top surface is substantially planar and substantially perpendicular to the convex and concave surfaces. The curved panel further includes a bottom surface extending between the bottom edges of the convex and concave surfaces. The bottom surface is substantially planar and substantially parallel to the top surface.

Abstract: A joint for a housing for electrical components has a series of extruded panels connected edge to edge. The first edge includes a slot defined by an inner wall and an outer wall and the second edge includes a blade inserted into the slot, the blade and the flexible wall including cooperating shoulders. The blade and slot are at an angle to the outer surface where a rib engages into an outer recess to seal the outer surface at the joint. A bridging member spans the joint to prevent spreading, while locking the flexible wall and carrying internal components. The housing can form a post or a receptacle on top of the post. The bridging members connect to end plates by screws extending though the plates so as to form an internal structure for the housing. Some of the connected panels can include cooling fins forming a cooling duct.

Abstract: A slatted recycling and refuse receptacle is provided with detents at the top for the mounting of a demountable top on the receptacle. Various tops can be mounted with various decorative treatments. Having the decoration on the top itself enables such decoration to be removed with the top so it doesn't interfere with removal of trash and recyclables from the receptacle through the top.

Abstract: An enclosure system for providing a visual barrier with respect to various objects, including a tank of the type used to store fuel, water and other liquid and gaseous materials. The enclosure system includes an enclosure and a lid covering the enclosure. The enclosure is attached to the tank and is made from opaque materials such as wood or dyed plastic. Vent openings are provided to prevent the accumulation of undesirable vapors, e.g., fuel vapors, that may escape from the tank and accumulate between the enclosure and the tank. An attachment mechanism is provided for supporting the enclosure in a predetermined position relative to the tank, e.g., so that the bottom of the enclosure is positioned a few inches above the surface on which the tank rests. An optional second attachment mechanism is provided for ensuring the enclosure remains so positioned relative to the tank.

Abstract: A simulated barrel garden for aquatic and terrestrial plants comprising a circumferential sidewall consisting of two sections of vertically extending barrel staves having a plurality of straps fastening the staves together in assembled relation, a barrel liner being inserted into the sidewall and mating with the sidewall top edges and forming a rigid, stand alone half barrel supporting the weight of the garden and a water related accessory mounted on a mounting bracket and fastened to the top rim of the liner. A second embodiment includes a cascade notch in the sidewall and a mating cascade lip formed in the barrel liner. Two additional embodiments of the barrel liner include a planter ring with a shelf in the center or a hole in the center.
