Abstract: A supported carbon having high surface area, high pore volume containing (i) molybdenum (ii) a metal of non noble Group VIII, (iii) phosphorous, is used for hydrometallization of heavy crude oil and residue. The catalyst contains about 6 to 15 wt % molybdenum as MoO3, about 1 to 6 wt % cobalt or nickel as CoO or NiO and phosphorus as phosphorous oxide. One characteristic of the catalyst is the portion of pores having pore diameter in the range of 200 to 2000 Angstrom of 20 percent or more. The catalyst prepared by chelating agent has higher hydrodesulfurization activity assuming that more dispersed active metals are present on this catalyst. Long run activity studies show that catalyst having only molybdenum supported on activated carbon has good stability with time-on-stream and very high metal retention capacity.

Abstract: Various embodiments of a system and method for authoritative item identification based on facility operations are described. Embodiments may include an authoritative item identification component configured to, for each particular item of multiple items in inventory of a materials handling facility, determine multiple identifiers for the particular item, where one or more of the multiple identifiers are electronically obtained from a unit of the particular item during operations of the materials handling facility. The authoritative item identification component may, for each of the multiple identifiers, determine a quantity of instances in which that identifier was electronically obtained from a given unit of the particular item. The authoritative item identification component may, based on a statistical analysis of the quantities, determine one of the multiple identifiers as being an authoritative identifier for the particular item.

Abstract: A toner composition with a novel surface additive package for developing images. The additive package includes sol-gel silica, a PDMS silica, an organic spacer such as PMMA and HMDS silica. The toner composition exhibits improved control of voltage, higher print density, lower toner amount remaining on the roll, lower toner usage, and reduced drum contamination. The toner composition also exhibits improved dry theological properties. These improved properties make this toner composition useful for higher speed printing while using less toner.

Abstract: A novel method for treating sulfide-containing wastewater is described which involves treating sulfide-laden biogas produced in a bioreactor in a sulfide oxidizing unit (SOU). Oxidation in the SOU is monitored by an oxidation reduction potential (ORP) probe which minimizes the input of air/oxygen to produce elemental sulfur without significant production of sulfate.

Abstract: Single component toners are provided with at least one surface additive including a large polymeric spacer, and processes for producing the same. In embodiments, the toner is a non-magnetic single component toner produced by emulsion aggregation methods. The large polymeric spacer additives provide excellent flow characteristics to the resulting toners, and reduce the incidence of clogging failure and print defects such as ghosting, white bands, and low toner density compared with conventionally produced toners.

Abstract: The present disclosure provides emulsion aggregation (EA) toner particles having less pigment on the particle surface and a more uniform pigment distribution.

The unified filter bank may also include a reconfigurable transform component that performs a transform as part of signal conversion for the multiple types of compressed audio bitstreams. The unified filter bank may also include complementary modules that perform complementary processing as part of the signal conversion for the multiple types of compressed audio bitstreams. The unified filter bank may also include an interface command controller that controls the configuration of the reconfigurable transform component and the complementary modules.

Abstract: Multiple microphone noise suppression apparatus and methods are described herein. The apparatus and methods implement a variety of noise suppression techniques and apparatus that can be selectively applied to signals received using multiple microphones. The microphone signals received at each of the multiple microphones can be independently processed to cancel echo signal components that can be generated from a local audio source. The echo cancelled signals may be processed by some or all modules within a signal separator that operates to separate or otherwise isolate a speech signal from noise signals. The signal separator can include a pre-processing de-correlator followed by a blind source separator. The output of the blind source separator can be post filtered to provide post separation de-correlation. The separated speech and noise signals can be non-linearly processed for further noise reduction, and additional post processing can be implemented following the non-linear processing.

Abstract: This disclosure describes audio mixing techniques that intelligently combine two or more audio signals into an output signal. The techniques allow audio to be combined, yet create perceptual differentiation between the different audio signals. The result is that a user is able to hear both audio signals in a combined output, but the different audio signals do not perceptually interfere with one another. The techniques are relatively simple to implement and are well suited for radio telephones.

Abstract: A catalyst for hydrotreating, especially hydrodesulfurization, of residua and heavy crudes is prepared by synthesizing the support from titanium and boehmite, to form either a titanium/alumina support (TiO2/Al2O3) or a titanium-alumina support (TiO2—Al2O3) that is thereafter provided with at least one hydrogenating metal from group VIB in oxide form and a promoter from group VIII also in oxide form. The (TiO2/Al2O3) support is prepared from boehmite, which is peptized by using an inorganic acid, then extruded, calcined and impregnated with a solution containing titanium, while the (TiO2—Al2O3) support is prepared by admixing boehmite with a titanium-containing solution, peptized using an inorganic acid, extruded and calcined to obtain the titanium-alumina support.

Abstract: This disclosure describes signal processing techniques that can improve the performance of blind source separation (BSS) techniques. In particular, the described techniques propose pre-processing steps that can help to de-correlate the different signals from one another prior to execution of the BSS techniques. In addition, the described techniques also propose optional post-processing steps that can further de-correlate the different signals following execution of the BSS techniques. The techniques may be particularly useful for improving BSS performance with highly correlated audio signals, e.g., from two microphones that are in close spatial proximity to one another.

Abstract: The invention relates to a method for synthesizing a hydroprocessing catalyst, wherein the support is prepared by mixing peptized aluminium with amorphous silica or with crystalline aluminium silicate as a catalyst component. The catalyst comprises a metal from group VIB and/or a metal from group VIIIB of the Periodic Table. The catalyst exhibits enhanced activity vis-à-vis hydrodisintegration, hydrodemetallization and hydrodesulphurization, and has a relatively stable life as a function of run time. Thus, the invention relates to a method for developing a catalyst for hydroprocessing heavy hydrocarbon feedstocks, which is characterized in that it comprises two steps: the first step involves optimization of the catalyst formulation with respect to textural properties, the number of acid sites and incorporation of the active metal; the second step involves evaluation with real feedstocks and the stability of the catalyst as is function of run time.
