    摘要: A method for the electrochemical production of ferrate salts in an aqueous electrolyte solution comprising one or more hydroxide components. Dramatically increased yields of ferrate salts are obtained from using a mixture of sodium hydroxide and potassium hydroxide. Preferably, both sodium hydroxide and potassium hydroxide are present in concentrations greater than 5 molar, most preferably at least 10 molar, i.e., 10 M NaOH and 10 M KOH. The anode is preferably a sacrificial anode made out of an iron-containing material to supply the iron necessary for the ferrate production reaction. The aqueous hydroxide solution, even a mixed potassium hydroxide (KOH) and sodium hydroxide (NaOH) solution, may be recycled and reused in the electrochemical cell, preferably after the extraction of the ferrate salt

    摘要: A cellular communication phone with integral headset retraction device is provided. The headset retraction device is integrally molded to a lower portion of the rear side of the phone. The headset retraction device includes a housing which serves to store a cable reel having a cable retracting mechanism and an electrical conducting cable. The electrical conducting cable includes a micro-sized microphone connected between an audio receiver earpiece and an auxiliary plug connector. An auxiliary plug storage receptacle is provided in order to prevent free suspension of the auxiliary plug connector. A cable guidance column is provided to aid in directing the electrical conducting cable into the retraction housing when being wound therein. An earpiece retention jacket is disclosed for supporting the audio receiver earpiece.

    摘要: The method for separating ferrate salts from a solution comprising providing contact between the solution of essentially of aqueous hydroxide and the ferrate salts and a surface having a magnetic attraction, magnetically securing the ferrate salts to the surface; and eliminating contact between the solution and the surface. Contact is provided by immersing the surface in the solution, passing the liquid ferrate mixture over the surface, or combinations thereof. The magnetic attraction may be induced by permanent magnets, electromagnets, and combinations thereof. The apparatus for ferrate production comprises an electrochemical cell having an iron-containing anode, cathode, and an aqueous hydroxide solution in fluid communication with both the anode and the cathode, and a magnetic separator in fluid communication with the aqueous hydroxide solution for separating ferrate salts from the aqueous hydroxide solution
