International Classification:

G06F 3/06

Abstract:

A method and a memory device are provided. A controller of the memory device retrieves a first command burst from a host memory. The first command burst includes a sequence of one or more commands from a first submission queue. The controller identifies that at least one command in the first command burst is at least one first fused command of a first set of fused commands. The first set of fused commands is to be processed atomically in the memory device, and a remainder of the first set of fused commands is on the first submission queue. The controller stores at least an identifier of the at least one first fused command in a set-aside buffer of the memory device.

Abstract:

Rubber compounds may comprise: an epoxidized polypentenamer rubber (CPR) and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles. One nonlimiting example is rubber compound comprising: phr to 90 phr of a styrene-butadiene rubber (SBR), a natural rubber (NR), and/or a butadiene rubber (BR); 10 phr to 50 phr of a epoxidized CPR and/or a hydrolyzed epoxidized CPR; and 10 phr to 200 phr of a filler comprising silica particles, wherein the SBR, the NR, the BR, the epoxidized CPR, and the hydrolyzed epoxidized CPR combined equal 100 parts. Rubber compounds comprising epoxidized CPR and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles may be useful in tire compositions.

Abstract:

A block copolymer comprising a PAO block derived from alpha-olefin monomer(s) having a carbon backbone comprising more than six (6) carbon atoms per molecule and a poly(alkyl methacrylate) block derived from alkyl methacrylate monomer(s) having an alkyl group comprising at least six (6) carbon atoms forms micelles in hydrocarbon solvents and lubricant oil base stocks with large space volume even at low overall molecular weight. The block copolymer of this disclosure is particularly advantageous as viscosity modifier for lubricant oil compositions.

International Classification:

E21B 7/24

Abstract:

A shock tool for reciprocating a drillstring includes an outer housing. The outer housing has a central axis, a first end, a second end opposite the first end, and a passage extending axially from the first end to the second end. In addition, the shock tool includes a mandrel assembly coaxially disposed in the passage of the outer housing and configured to move axially relative to the outer housing. The mandrel assembly has a first end axially spaced from the outer housing, a second end disposed in the outer housing, and a passage extending axially from the first end of the mandrel assembly to the second end of the mandrel assembly. The mandrel assembly includes a mandrel and a first annular piston fixably coupled to the mandrel. The first annular piston is disposed at the second end of the mandrel assembly and sealingly engages the outer housing.

Abstract:

A shock tool for reciprocating a drillstring includes an outer housing and a mandrel assembly coaxially disposed in the outer housing. The outer housing has a radially inner surface including a plurality of circumferentially-spaced splines. The mandrel assembly includes a mandrel having a radially outer surface including a plurality of circumferentially-spaced splines and a plurality of circumferentially-spaced troughs. Each spline of the outer housing is disposed in one trough of the mandrel. Each spline of the mandrel includes a top surface, a first lateral side surface extending radially from the top surface, a second lateral side surface oriented parallel to the first lateral side surface, and a bevel extending from the top surface to the second lateral side surface. Each spline of the mandrel also includes a pocket in the second lateral side surface extending radially from a bottom surface of a trough to the bevel.
