Abstract: A composition and method for breaking down and denaturing friction-reducing compound introduced into the ground during the drilling of oil wells and for destroying other contaminants and biohazards naturally present within and artificially introduced into oil wells, which are formed as a result of the drilling and pumping processes. The composition comprises several species of oxidizing agent compounds that are effective in breaking down hydrogen sulfide produced by bacteria as well as the friction-reducing polymer used during drilling and several other organic compounds.

Abstract: A fixed-blade knife includes a unitary blade having an implement, a tang, and a pivot region between the implement and the tang. The unitary blade is disposed between a pair of parallel and spaced-apart side pieces that pivot to cover or expose the implement. In the pivoted position wherein the implement is exposed, the side pieces form part of the handle that is used to grasp the knife. A locking structure locks the side pieces in a selectable position, and a limit structure prevents overrotation of the side pieces.

Abstract: An audio input interface (122) receives a digital audio signal and identifies an audio bitstream which is optionally decrypted by a decryption unit (123), and decoded by an audio decoding unit (124). An audio digital to analog converter (126) converts the decoded audio bitstream to an analog audio signal which is optionally decrypted by an audio analog decryption unit (127). A video input interface (142) receives a digital video signal and identifies a video bitstream which is optionally decrypted by a video digital decryption unit (143), and decoded by a video decoding unit (144). A video digital to analog converter (146) converts the decoded video bitstream to an analog video signal that is optionally decrypted by a video analog decryption unit (147). An analog transmitter (150) mixes the analog audio signal and analog video signal and transmits an analog wireless output signal to an analog wireless device (110).

Abstract: An electrodialysis treatment system utilizing a plurality of disparate layers of an electrodialysis cell stack for separation of components in liquid mixtures. The system for electrodialysis treatment for purification and deionizing liquids includes providing an operation of pretreatment by filtration for removal of inorganic and organic contaminants and generating a filtrate effluent. An adsorbing operation for adsorbing organic contaminants from the filtrate effluent of the pretreatment operation is provided by utilizing activated carbon adsorption and generating a liquid fraction. A deionizing operation for continuously purifying the liquid fraction is provided by utilizing an electrodialysis stack having a plurality of ion exchange membranes and separating gaskets for selectively removing contaminant ions from the liquid fraction of the adsorbing operation.

Abstract: An improved exercise bar for performing chin-up and pull-up exercises. According to a preferred embodiment, the exercise bar comprises an elongate member having a first upper arcuate portion extending along the length thereof and an angled portion extending downwardly therefrom. A third portion extends from the second angled portion and is preferably oriented such that, in use, the same is in generally perpendicular orientation with level ground. The first arcuate portion is designed to support the phalanx bones of the fingers, whereas the second angled portion supports the bones and muscles located in the palmar sections of the hands. The third portion supports the distal-most ends of the wrist bones. The exercise bar may be mountable upon a wall or may be formed as part of a free-standing apparatus. The exercise bar may further be formed to have a generally arcuate shape for the performance of wide-grip pull-up exercises, or may further include an attachment mechanism for use in lat pull-down exercises.

Abstract: A safety web and elongated pry bar for retaining the lid of a drum during opening of the lid. Safety web 10 is adapted to form a secure containment volume 22 in which lid 14 can be manipulated, and that prevents lid 14 from becoming a projectile. Safety web 10 includes a belt 20 for securing the safety web to the drum. The ends of belt 20 are secured to a ratcheting turnbuckle 25 that allows adjustment of the length of belt 20 providing for universal fit of a given safety web on a variety of different sizes of drums. Safety web 10 further includes a plurality of radial straps 30 that are radially disposed about belt 20. The ends 32 of radial straps 30 are fixedly secured to belt 20. Radial straps 30 are further fixedly secured to each other at a central point 35 defined by the midpoint of each radial strap 30. An annular strap 40 is provided on safety web 10 between belt 20 and central point 35. Annular strap 40 is fixedly secured to each radial strap 30.
