Abstract: A cutting element for use on a drill bit is disclosed. The cutting element includes a polycrystalline diamond table having a multi-tiered surface. The polycrystalline diamond table has at least a first cutting surface and a second cutting surface. The polycrystalline diamond table has a step between the first and second cutting surfaces. The step is transitional surface feature between the first and second cutting surfaces, which are positioned at different elevations in the polycrystalline diamond table.

Abstract: Scheduling traffic of a communication session between an application on WiFi and another device, by: receiving traffic of a first session; determining that the traffic belongs to a first classification; determining that a time allocated to the first classification times a second classification airtime is less than or equal to a time allocated to the second classification times a first classification airtime; selecting a counter associated with the first session as being the largest of multiple counters each associated with a different communication session of multiple communication sessions (which include the first session); determining that the traffic of the first session is to be scheduled for transmission to the application over WiFi in response to the counter being determined to be the largest of the plurality of counters; and based on the traffic being determined to be scheduled, increasing the airtime associated with the first classification and decreases the counter.

Abstract: The present invention discloses a method for preparing a super absorbent resin including the following steps: 1) adding an inner-crosslinking agent, an active promoter, and an initiator to a solution of an unsaturated monomer in water, deoxygenating by bubbling nitrogen therethrough, and then undergoing free radical polymerization to obtain a gel; 2) reacting the gel with a neutralizing agent, extruding, and granulating to obtain a product; 3) drying, pulverizing, sieving, and fixing the particle size combination of the product to obtain powdered raw particles; 4) adding a surface crosslinking agent to the powdered raw particles and performing surface crosslinking by heating to obtained crosslinked particles; and 5) subjecting the crosslinked particles to anti-caking treatment to obtain a super absorbent resin.

Abstract: A thermally stable polycrystalline diamond compact is created by (i) preforming an annular thermally stable polycrystalline from a diamond plate, (ii) preforming a substrate with a projection that has an interfacial mating surface that is a negative topology of the annular thermally stable polycrystalline, (iii) and brazing the two components together. The resulting polycrystalline diamond compact can be made thermally stable because cobalt and other catalysts can be leached out of the thermally stable polycrystalline. The thermally stable polycrystalline can be attached to the substrate by brazing, which due to the topology of the thermally stable polycrystalline and the substrate with a projection will unexpectedly have sufficient blaze shear strength to be used in demanding applications.

Abstract: A cobalt-boron alloy is used as the matrix in a polycrystalline diamond compact. The matrix is hot isostatic pressed with tungsten carbide to form a substrate. The substrate is then high-pressure, high temperature sintered with a diamond powder, preformed and acid-leeched diamond plate, or another ultra-hard material in a press mold to sweep the matrix, thereby creating an ultra-hard polycrystalline compact at a temperature 400° C. lower and with less graphitization than conventional techniques using cobalt binder. The compact is stronger and has a longer useful life than conventional compacts.

Abstract: A mixture of trialkyl phosphine oxides (HTRPO) was prepared having the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are same or different alkyl groups of 5 to 9 carbon atoms and the total number of carbon atoms and the total number of carbon atoms per molecule is from 15 to 27. The mixture of trialkyl phosphine oxides (HTRPO) is useful as an extractant for recovering acids from aqueous solutions.
