  • Patent number: 10344140
    Abstract: A crystalline Boehmite product and a method of forming said product is provided in which the crystalline Boehmite exhibits an average particle size (d50) that is less than 7,000 nanometers. This method comprises preparing an aqueous slurry by mixing together water, large aluminum oxide precursors, a highly dispersible Boehmite grade, and optionally, an organic dispersing agent; adjusting the pH of the slurry; heating the slurry for a predetermined duration of time; collecting the slurry to form a wet cake; and drying the wet cake to obtain the crystalline Boehmite product. The crystalline Boehmite product may be mixed with a plastic resin to form a flame retardant plastic mixture, which can be subjected to a conventional plastic processing method to form a flame retardant composite.

  • Publication number: 20190112198
    Abstract: Mesoporous, zirconium-based mixed oxides and a method of making the same comprises: injecting a polyvalent metal-containing solution into an electrolyte solution to form a mother liquor; forming a precipitate; aging the precipitate in the mother liquor to form the mixed oxides; washing the mixed oxides with an aqueous medium; drying and collecting the mixed oxides. The pH of the electrolyte solution exceeds the isoelectric point for zirconium-based mixed oxides. The mixed oxides exhibit a single particle size distribution, improved Ce02 reducibility in the presence of Rhodium, a decrease in surface area after calcination (800-1 100° C.) that is not more than 55%, and a tetragonal/cubic structure after calcination. After calcination at 1 100° C. for 10 hours in air, the mixed oxides exhibit a surface area >25 m2/g, a pore volume >0.20 cm3/g, an average pore size >30 nm, and an average crystallite size between 8-15 nm.

  • Publication number: 20140222540
    Abstract: A platform for a loyalty program provides an interface allowing a consumer to create a benefit tailored for his/her needs. In one embodiment, a consumer accesses the platform via a web-based interface, and selects benefit/reward parameters including but not limited to the nature of the event triggering award of the benefit, the source (i.e. retailer) of the benefit, the nature of the benefit (i.e., discount based upon purchase price or accumulated loyalty points), and/or the events allowing accrual of loyalty points. The interface communicates the inputted parameter to an engine of the loyalty program. The platform would then check the inputted parameter against any constraints, such as parameters of an existing loyalty program in which the consumer is already enrolled.

  • Publication number: 20080059307
    Abstract: Collaborative constituents collaborate to develop a loyalty program within a transaction processing system. Transmissions addressed to the collaborative constituents are formed and received from the collaborative constituents containing suggested parameters for the loyalty program. At least one remaining parameter for the loyalty program that a set of remaining collaborative constituents have agreed upon is determined. Another transmission addressed to each of the collaborative constituents in the set of remaining collaborative constituents is formed, the another transmission including the remaining parameters for the loyalty program.

  • Publication number: 20070135839
    Abstract: A suture needle construct and method for extracapsular ligament reconstruction in mammals. The joint is first is first explored, and the damaged ligament and meniscus are debrided. The joint capsule is closed and a tunnel is created at the appropriate location in the proximal tibia for tibial fixation. Subsequent to the formation of the tibial tunnel, a suture having a substantially curved needle at one end and a substantially straight needle at the other end is brought in the proximity of the joint. The suture is passed around the lateral fabella using the substantially curved needle, then deep to the patellar ligament using the substantially straight needle, and through the tibial tunnel using the straight needle. The needles are cut off, and the sutures are tensioned over repair site.

  • Publication number: 20060205076
    Abstract: An osteochondral centrifugation system for providing an osteochondral centrifuged core from a graft such as femoral condyle, for example. The centrifugation system may be used either in the operating room or, alternatively, at a tissue banking facility at the time of processing. The osteochondral centrifuged core is formed by (i) removing an osteochondral core from a graft; (ii) placing the osteochondral core in a centrifugation system to remove blood, lipids, or other potentially antigenic or contaminating materials, and to obtain a centrifuged core; and (iii) optionally, subjecting the centrifuged core to a material that reduces the chance of disease transmission and aids in the healing of the recipient site to which the centrifuged core is to be transferred.
