Abstract: A towable mover includes a flexible mat and a hollow tow bar substantially contained in a sleeve at the leading edge of the mat. A tow rope is coupled to each end of the tow bar for towing. Couplings include a plug assembly securely received within the interior space at an end of the tow bar and a rope coupling assembly attached to the plug assembly. The plug assembly includes a resilient elastomeric cylindrical plug, the diameter of which swells when the ends are squeezed together by tightening a bolt. The rope coupling assembly is external to the tow bar and external to the sleeve. The sleeve is disposed between portions of the mat that may freely fold to allow passage through narrow spaces.

Abstract: A method of exercise includes partially filling (not more than 70% full) a symmetrical hollow body of an exercise device with water, grasping a pair of opposed handles attached to the hollow body, positioning the device at a height and orientation for a first set of motions, and rapidly oscillating the device at a frequency (?2 HZ) to transform the water from a static state into a dynamic state in which the center of mass oscillates and hydrodynamic forces arise. Optionally, an additive such as viscosity enhancer or beads for audible effect may be introduced in the water.

Abstract: This disclosure includes a process that unexpectedly can produce very inexpensive graphene and a new compound called graphenol in particulate or dispersions in solvents. The process can also produce graphene layers on metallic and nonmetallic substrates. Further, the graphenol and graphene can be utilized to form nanocomposites that yield property improvements exceeding anything reported previously.

Abstract: An intercalated layered silicate comprises a layered silicate and an intercalating agent sorbed between the silicate layers of the layered silicate. The amount of intercalating agent is effective to provide an average interlayer spacing between the silicate layers of at least about 20 ?. The intercalating agent has a formula selected from formulas I through VII described herein. The intercalated layered silicate may be exfoliated by mixing it with a matrix medium and adding sufficient energy to form a dispersed-particle composition. A packaging film, such as a food packaging film, may comprise the dispersed-particle composition.
