Title: A process for the instantaneous control of precipitation of nickel and cobalt present in the leach liquor, by adjusting the ph of the solution
Inventor: TORRES VANESSA MACEDO
IPC: C22B3/44
Filed: 2007-06-25
Granted: 2016-10-04
Abstract: The present invention concerns a process for the instantaneous control of the precipitation of nickel and cobalt present in a leach liquor by adjustment of the pH-value. Said leach liquor is obtained by pressurized acidic leaching of laterite ores and additionally contains aluminium, ferric and ferrous iron and chromium among others. The process comprises the following steps: precipitation of aluminium, ferric and ferrous iron, chromium etc. by increasing the pH- value by adding a suitable reagent such as lime and/or limestone, following precipitation of nickel and cobalt by further increasing the pH-value of the liquor, finally separating the precipitate from the low-content nickel and cobalt solution. The nickel and cobalt precipitate can be used for further refinement. In order to keep the process conditions constant, the steps of increasing the pH-value are controlled simultaneously.

Abstract: A microflow apparatus for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts. The posts are spaced across the width of a collection region in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, have arcuate cross-sections, and are randomly arranged so as to disrupt streamlined flow. Sequestering agents, such as Abs, are attached to all surfaces in the collection region via a hydrophilic coating, preferably a hydrogel containing isocyanate moieties or a PEG or polyglycine of substantial length, and are highly effective in capturing cells or other targeted biomolecules as a result of such streamlined flow disruption.

Abstract: A conditional access system (CAS) computer in a downloadable CAS receives a downloadable management certificate (DMC) and determines, using the DMC, security information including a DMC key size and an expiration time of a DMC subordinate certificate authority (sub-CA) certificate, for the client device. The CAS computer then determines whether the DMC is valid based on the expiration time of the DMC sub-CA certificate. If the DMC is determined to be valid, the CAS server sends a cryptographic identity for the client device and a CAS client to the client device protected using the DMC. At a later time, if the DMC key size is considered to be still sufficiently secure, the validity of the DMC is extended by issuing a new DMC sub-CA certificate with the same public key as the original DMC sub-CA certificate.
