Abstract: The present invention includes roller massage systems that are adjustable for individual comfort and use and methods related thereto. In one illustrative embodiment, a roller is centrally located on a generally U-shaped framework formed by two opposite symmetrical handles. Each handle may end in a rounded knob to allow for massage with pressure applied at particular points and may be disposed at a particular angle from the remainder of the handle for advantageous use. The roller may be interchangeable to allow a variety of rollers to be utilized providing different forms of massage. The handles may be adjustable at different points to allow users of different sizes to utilize the system.

Abstract: A method for modifying the electrostatic discharge (ESD) characteristics of a polymeric material by integrating metallocene moieties as constituents of the polymer structure. In a preferred embodiment, the metallocene is part of the polymer backbone structure. In another preferred embodiment, the metallocene moieties are in sufficiently close proximity to one another such that electrostatic charge propagation is promoted. In another preferred embodiment, the metallocene is ferrocene. In another embodiment, an article is formulated from, or coated with, a polymeric composition containing metallocene as a polymer constituent. The subject invention includes novel polymeric compositions. Polymeric compositions of the subject invention, and articles made therefrom, exhibit electrostatic dissipative properties which are useful in preventing destructive electrostatic discharge.

Abstract: A metal spray apparatus is provided with a supersonic nozzle. Molten metal is injected into a gas stream flowing through the nozzle under pressure. By varying the pressure of the injected metal, the droplet can be made in various selected sizes with each selected size having a high degree of size uniformity. A unique one piece graphite heater provides easily controlled uniformity of temperature in the nozzle and an attached tundish which holds the pressurized molten metal. A unique U-shaped gas heater provides extremely hot inlet gas temperatures to the nozzle. A particularly useful application of the spray apparatus is coating of threads of a fastener with a shape memory alloy. This permits a fastener to be easily inserted and removed but provides for a secure locking of the fastener in high temperature environments.
