Abstract: A method and system for converting copper cyanide to copper oxide is provided. The method includes contacting a copper cyanide solution with an acidic solution in a precipitation tank under reaction conditions sufficient to produce a copper cyanide slurry, removing the copper cyanide slurry from the precipitation tank, separating solid copper cyanide from the copper cyanide slurry in a first separation device, removing the solid copper cyanide from the first separation device, contacting the solid copper cyanide with a sodium hydroxide solution in a production tank under reaction conditions sufficient to produce a copper oxide slurry, removing the copper oxide slurry from the production tank, separating solid copper oxide from the copper oxide slurry in a second separation device, and removing from the second separation device any residual sodium hydroxide not reacted during the process of contacting the solid copper cyanide with the sodium hydroxide solution in the production tank.

Abstract: A method of inferring fluid flow speed through a passage comprises receiving a first signal having a frequency and phase corresponding to that of a first ultrasonic wave detected after passing through the fluid in a direction with a component opposed or aligned to a main direction of the fluid's flow. Receiving a second signal having a frequency and phase corresponding to that of a second ultrasonic wave detected after passing through the fluid in a direction with a component different to that of the first ultrasonic wave with respect to the main direction of the fluid's flow. Inferring the fluid flow speed through the passage based on the relative phase shift between the first and second signals.

Abstract: A measurement process, intended for measuring at least one wheel of a train, including an acquisition step, during which a plurality of profiles of at least a part of the wheel are acquired by plurality of optical sensors, as the train moves in front of the optical sensors, a mapping step, during which, for each optical sensor, the profiles acquired by the optical sensor are joined by a control module, to obtain a map of the part of the wheel further transformed into a cloud of points, a rejoining step, during which the clouds of points obtained from the optical sensors are joined to form a three-dimensional image of the wheel, and an analysis step, during which a plurality of reference points and reference distances are measured on the three-dimensional image.

Abstract: A flexural ultrasonic transducer is disclosed. The ultrasonic transducer comprises a sealed case which includes a flexible membrane and which defines a sealed cavity. The sealed case has an inside and an outside. The ultrasonic transducer comprises an active element, for example, a piezoelectric element, inside the sealed case supported on the flexible membrane. The ultrasonic transducer includes a liquid in the cavity. The sealed case includes a resilient portion between the inside and outside of the case for allowing equalization of pressure between the inside and the outside of the case. The resilient portion may comprise resilient walls or a thin-wall section, the flexible membrane or the case.

Abstract: Disclosed is a method of inferring fluid flow speed through a passage. The method comprises receiving a first signal having a frequency and phase corresponding to that of a detected first ultrasonic wave, the first ultrasonic wave having been detected after passing through the fluid in a direction with a component opposed or aligned to a main direction of the fluids flow. Further, receiving a second signal having a frequency and phase corresponding to that of a detected second ultrasonic wave, the second ultrasonic wave having been detected after passing through the fluid in a direction with a component different to that of the first ultrasonic wave with respect to the main direction of the fluids flow. Further, inferring the fluid flow speed through the passage in accordance with the relative phase shift between the first and second signals. The frequencies of the first and second ultrasonic waves are substantially the same or are substantially harmonics of one another.
