Abstract: A power rack attachment system and associated method are provided. An example of the power rack attachment system includes a hand crank and a gearbox coupled to the hand crank, the gearbox comprising a plurality of gears connected to a lead screw, wherein the plurality of gears causes the lead screw to rotate in a vertical translation based on a radial motion of the plurality of gears. The power rack attachment system includes a guide housing connected to the gearbox, the guide housing comprising the lead screw, a vertically translating nut, and a guide rod, wherein the lead screw is connected to the vertically translating nut, such that rotation of said lead screw leads to vertical translation of said vertically translating nut. The power rack attachment includes a j-cup connected to the vertically translating nut, wherein the vertical translation of the vertically translating nut causes vertical translation of said j-cup.

Abstract: An electrolytic cell for measuring the concentration of a species such as oxygen is constructed by depositing closely spaced interleaved inert electrode surfaces on the surface of an insulating substrate and covering the electrode surfaces with a thin film of electrolyte and permeable membrane. The electrolyte is selected so that the species being measured is generated at one electrode surface and consumed at the other with no net reaction in the electrolyte. Alternatively, a cylindrical configuration may be formed by closely winding two thin electrode wires about a cylindrical base and covering with an electrolyte and a membrane.
