Abstract: The present invention relates, generally, to a method and apparatus for electrowinning metals, and more particularly to a method and apparatus for copper electrowinning using the ferrous/ferric anode reaction. In general, the use of a flow-through anode—coupled with an effective electrolyte circulation system—enables the efficient and cost-effective operation of a copper electrowinning system employing the ferrous/ferric anode reaction at a total cell voltage of less than about 1.5 V and at current densities of greater than about 26 Amps per square foot (about 280 A/m2), and reduces acid mist generation. Furthermore, the use of such a system permits the use of low ferrous iron concentrations and optimized electrolyte flow rates as compared to prior art systems while producing high quality, commercially saleable product (i.e., LME Grade A copper cathode or equivalent), which is advantageous.

Abstract: Methods and systems are described for preventing disconnection of a module from a module connector prior to initiating a shutdown routine and for preventing operation of the module unless a retention device is engaged. The system includes a switch having a first state for allowing operation of a module and a second state for initiating shutdown and/or preventing operation of the module. At least one retention device prevents disconnection of the module from the module connector. A covering member is movable between first and second positions, but is prevented from moving to the first position when the retention device in not engaged. In the first position, the covering member prevents access to the retention device and the switch is in the first state and in the second position the covering member allows access to the retention device and transitions the switch to the second state.

Abstract: A spraying apparatus for spraying liquid surface treatment material which includes a gas inlet, a liquid inlet and an outlet nozzle. The apparatus also has a needle valve for regulating the supply of surface treatment material to the nozzle. The needle valve is at least partially located within a gas outlet chamber and is adapted so as to cause minimal disruption to the gas flow from the gas inlet to the nozzle. To further aid gas flow efficiency, the gas supply passage is substantially straight, the outlet chamber has a laterally outwardly tapering inlet and an inwardly tapering outlet and a smooth radius of curvature from the gas supply passage into the outlet chamber. There is also provided a control means for controlling the axial movement of the needle valve, the control means being provided with indicator means so as to provide an accurate, repeatable control means.

Abstract: A pedal positioning apparatus has a ratcheting assembly that includes a handle, a shaft, an attachment arm that extends from the handle and at least one trigger. The pedal positioning apparatus also includes a lever arm having a first end and a second end. The lever arm is pivotally connected to the handle at one end and also includes a pedal hooking feature at the other end. The pedal positioning apparatus further includes a bracket connected to the bar to support a pedal-contacting pad.

Abstract: This invention relates to a muffler or mute for saxophone and other wind instruments comprising a muffling bag (10) with a durable external vinyl layer (12) and an internal layer of sound absorbing material (14). The saxophone (16) is entirely ensconced inside the saxophone muffler (except for the mouthpiece), and is securely held therein by an internal carriage assembly (30). The carriage assembly spaces and positions the saxophone, and hence the sound emanating from the keys as well as the bell of the saxophone is muted equally efficiently. Pockets (20) provided on the two sides of the saxophone enable the saxophonist to have access to the keys of the saxophone. A second hard-shell embodiment also functions as a mute and doubles as a saxophone carrying case.
