A support for a musical keyboard instrument has a first leg, a second leg and an adjuster. The first leg is pivotally connected to the second leg and a rod is formed in a sidewall of the second leg. Two first spiral surfaces are respectively formed in a free end of the rod and the adjuster is provided adjacent to the rod. The knob is formed on the adjuster and has two second spiral surfaces respectively formed thereon and mated with the first spiral surfaces. When the second spiral surfaces are ...

A method of enhancing oil production from an oil bearing formation includes the steps of providing a first borehole in a first region of the formation and a second borehole in a second region of the formation. A first electrode is positioned in the first borehole in the first region, and a second electrode is positioned in proximity to the second borehole in the second region. A voltage difference is established between the first and second electrodes to create an electric field across the plugg...

The present invention is a material and method that enables creation of an in situ pumping action within a matrix or otherwise porous media. This pumping action may be used to move materials, namely fluids, through the matrix or porous media to a gathering point. This pumping action may also be used as a vibrational source, using the movement of the matrix itself as the radiator of vibrational, typically acoustic, energy. This vibrational energy may be used for a variety of purposes.

A method is provided for recovering oil from a subterranean oil-bearing formation. One or more pairs of electrodes are inserted into the ground in proximity to a body of oil in said formation. A voltage difference is then established between the electrodes to create an electric field in the oil-bearing formation. As voltage is applied, the current is manipulated to induce oxidation and reduction reactions in components of the oil. The oxidation and reduction reactions lower the viscosity in the ...

A down hole heating system for use with oil and gas wells which exhibit less than optimally achievable flow rates because of high oil viscosity and/or blockage by paraffin (or similar meltable petroleum byproducts). The heating unit the present invention includes shielding to prevent physical damage and shortages to electrical connections within the heating unit while down hole (a previously unrecognized source of system failures in prior art systems). The over-all heating system also includes h...

Ion exchange resins contaminated with a radioactive component are treated by exposing the contaminated ion exchange resins to a bound radio frequency electric field for uniformly heating them to drive off water. The dried ion exchange resins are then uniformly heated by a transversely uniform bound radio frequency electric field to a second higher temperature which chemically inactivates the functional groups of the ion exchange resins to destroy their hydrophilic property and convert them to a ...

An ionically permeable separator for a LeClanche cell, and methods of making and using same, are provided for in the invention. The separator comprises a Kraft paper separator and a corrosion-inhibiting coating thereupon selected to prevent corrosion of a zinc anode of the LeClanche cell. The separator may be configured for use in round or flat LeClanche cells. The separators of the invention may be used in heavy duty batteries containing an electrolyte comprising zinc chloride as a primary comp...

A guitar stand has a hollow upper block, a hollow main rod inserted in a bottom of the hollow upper block, a hollow lobe-shaped seat disposed on the hollow main rod, and a connection seat and the hollow lobe-shaped seat fastened by a screw spindle. A first pivot joint is disposed on an upper end of a first hollow leg. A second pivot joint is disposed on an upper end of a second hollow leg. The second pivot joint is inserted in the first pivot joint. The connection seat has a screw rod fastening ...

A method and apparatus for subterranean thermal conditioning. The first step involves providing a tubular magnetic induction apparatus. The second step involves positioning the magnetic induction apparatus into a subterranean environment. The third step involves supplying voltage waves to the magnetic induction apparatus thereby inducing a magnetic field in and adjacent to the magnetic induction apparatus to thermally condition the subterranean environment. This method and apparatus has applicat...
