Abstract: A metal recovery electrochemical cell includes a metal-based anode; a metal-based cathode; and a metal-based housing with a conical shape and a draft angle of about 0.01 to about 1 degree, the draft angle of the metal-based housing being an angle between a vertical centerline of the metal-based housing and an adjacent vertical side of the metal-based housing, when both are extrapolated to form an angle.

Abstract: Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. Maintenance and control of the sub atmospheric pressure exerted may be provided by such devices while minimizing discomfort to the user. The devices may be configured to be worn inconspicuously underneath clothing.

Abstract: Example embodiments may include an apparatus for providing negative-pressure therapy with a push-to-release actuator. The actuator may be a key insertable through a keyway in the apparatus to engage a movable barrier, such as a piston. The actuator may also be used to lock the barrier in a primed position. Pressing on the actuator can release the barrier and activate the apparatus for negative-pressure therapy. In some examples, the actuator may comprise a shaft, a latch, and a spring biasing the latch toward the shaft. The latch may comprise an opening toward a proximal end of the shaft. The apparatus may comprise a receptacle for receiving the actuator, and a keeper may disposed within the receptacle for coupling to the latch. In some embodiments, the keeper may comprise a base protruding from the wall, and a ledge extending from the base toward the second aperture.
