A baseball bat or the like comprised of one or more continuous spiral wound layers of wood, cellulose, or other like material rolled in a spiral fashion from the center to the outermost surface. The cellulose or other material is bound to each subsequent layer with a thin layer of resin, glue, epoxy, or other binding material of adequate strength to hold the layers together for multiple impacts by a baseball or other object. This spiral wound composite roll, in its final configuration, is of comparable density, weight and balance to ash, maple or oak material commonly used in baseball bat construction. The composite roll can be machined to a shape consistent with the shape and balance of traditional baseball bats.

A ferrule for use in optical fiber connections has an optical fiber containing a bore extending therethrough. Within the bore is a member of shaped memory alloy (SMA) which clamps and affixes the fiber firmly in place within the ferrule without the necessity of cementing the fiber in place. The shaped memory alloy has two states: the initial or primary state and the secondary or deformed state. In the embodiments of the invention, the member is deformed from the initial state to the secondary state and the fiber is inserted in the ferrule. The member is then returned to the primary state in which it firmly clamps the fiber within the ferrule.

An aliphatic polyamide film or fibrous material is employed for electrical insulation in individual conductors, groups of conductors, magnet wire, magnet wire coils, and layers in liquid filled electrical transformers. The material is stabilized with additives that produce improved moisture resistance, moisture stability, thermal stability, thermal conductivity, reduced insulation thickness, reduced shrinkage, and improved insulation elasticity for the insulation material thereby providing a longer useful life for the material.

Systems and / or methods of waste disposal use human-made caverns that are constructed within deep geological formations. A given human-made cavern may be constructed by first drilling out a vertical wellbore to a deep geological formation. Then a bottom portion of the vertical wellbore is jet drilled using an abrasive jetting fluid to form a launch chamber of void volume, that is sized to fit a reaming tool in its deployed open configuration. A reaming tool, in a closed configuration, is then inserted into the vertical wellbore for landing in the launch chamber. The reaming tool is then deployed into its open configuration while in the launch chamber. Reaming operations then occur from the launch chamber directed downwards within the deep geological formation, forming a given human-made cavern. The newly formed human-made cavern may be conditioned and / or configured for receiving amounts of the waste for long-term disposal and / or storage.
