Title: Cell for metal electrowinning
Inventor: TEZANOS ENRIQUE HERMANA
IPC: C25C7/02
Filed: 1986-06-23
Granted: 1992-11-17
Abstract: ABSTRACT           An electrowinning cell for metal electro-winning comprises an anode and a cathode with the cell  having  an  electrical  field  in  the  inter-electrodic space between the cathode and the anode. The  cathode  comprises  a  hollow  electrode  which defines an interior and includes conductive metallic cathodic plates with orifices in the cathodic plates. The  anode  is positioned  externally of  the hollow interior of the cathode.    The electrolyte can be introduced  with  the  necessary  pressure  into  the interior of the cathode in order that the electrolyte flows  to  the  interelectrodic  space  through  the orifices  and  is  subjected  there  to  the  existing electrical field.    Electrodeposition of cations to form a metal deposit on the external surface of the cathodic plates then takes place.   The orifices are formed  in  insulating  inserts  in  the  conductive metallic plates in order to avoid metal deposition around the orifices.

Title: Measurement of flow rate of power from a hopper
Inventor: GIANELLA EDWARD P
IPC: G01F1/74
Filed: 1987-11-04
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE            In a system and a method for measuring the rate at which powdered material flows from a container wherein a first analog signal representing the weight of the container is produced, the analog signal is differentiated to obtain a second signal corresponding to the flow rate and the second signal is passed through an adaptive filter.  The adaptive filter includes a first low pass filter having a first time constant for producing a third signal and a second low-pass filter to produce a fourth signal.  The time constant of the second filter is varied between a minimum equal to the time constant of the first filter and a maximum equal to a preselected multiple of the time constant of the first filter by comparing the absolute value of the difference between the third and fourth signals to a preselected deadband and effecting the maximum time constant when the absolute value of the difference is less than the deadband and the minimum, time constant when the absolute value of the difference is greater than the deadband.  A combination signal is provided from the fourth signal during the time when the absolute value of the difference is less than the deadband and the third signal during the time when the absolute value of the difference is greater than the deadband.  The combination signal is scaled to indicate the powdered material flow rate.
