Abstract: The residual hydrogenation catalyst from the hydrogenated nitrile rubber solution is recovered by using two steps such as (1) the catalyst extraction step with an ammonium salt and water (optionally including an oxidation step) to extract catalyst from the HNBR polymer chain to the solvent and then (2) the separation/column recovery step with the column packed with functional ion exchange resins for the separation of ammonia-catalyst complex from hydrogenated nitrile rubber solution and the column recovery for the high catalyst recovery with functional groups of resins. The ammonium salt for the catalyst extraction step is selected from ammonium chloride, ammonium bromide, ammonium iodide, and ammonium acetate. The functional groups in the functional ion exchange resins for packing the column is selected from thiourea, thiouronium, thiol, amine, diamine, triamine, TMT, dithiocarbamate, and carbodithioate.

Abstract: An automatic power control circuit for a laser driver includes precharge circuitry to precharge inputs to a comparator receiving an indication of laser output power, for example from a monitor photodiode. The precharge circuitry can be selectively activated when a laser driven by the laser driver is operating in burst mode, as opposed to operating in continuous mode. In addition, a digital up-down counter may be used to increase or decrease a digital value used to set a bias level for the laser, with the digital up-down counter counting up if the comparator indicates the laser output is too low and counting down if the comparator indicates the laser output is too high.
