Locating grains in storage using grain table to grain-range table compression
A “grain” is a unit of space allocation in a virtual disk. Grains are represented in physical storage only when used, that is, when they contain data. Grains may be located in storage using an in-memory grain-range table. The grain-range table is derived from a grain table in storage. A grain-range table includes entries for the starting grains of incrementing and or decrementing ranges; grain-table entries that do not start a range are omitted in the grain-range table. Accordingly, a grain-range table can serve as a compressed form of a grain table. This compression makes it feasible to store large numbers of grain-range tables in memory in cases where it would not be feasible to store the corresponding grain tables in memory. As a result, one rather than two storage accesses are require per storage access request, resulting in a substantial performance improvement. |

Diffractive optical elements with asymmetric profiles
In an optical display system that includes a waveguide with multiple diffractive optical elements (DOEs), gratings in one or more of the DOEs may have an asymmetric profile in which gratings may be slanted or blazed. Asymmetric gratings in a DOE can provide increased display uniformity in the optical display system by reducing the “banding” resulting from optical interference that is manifested as dark stripes in the display. Banding may be more pronounced when polymeric materials are used in volume production of the DOEs to minimize system weight, but which have less optimal optical properties compared with other materials such as glass. The asymmetric gratings can further enable the optical system to be more tolerant to variations—such as variations in thickness, surface roughness, and grating geometry—that may not be readily controlled during manufacturing particularly since such variations are in the submicron range. |

A turbine blade for a gas turbine employs film cooling to enhance cooling performance. The turbine blade includes an outer surface; and at least one film cooling hole formed in the outer surface, each film cooling hole including a cooling channel extending inside the turbine blade to guide cooling air toward the outer surface, an outlet communicating with one end of the cooling channel to discharge cooling air to the outer surface, and a plurality of protrusions formed on an inside surface of the outlet and arranged along a longitudinal direction of the outlet. The protrusions protrude inwardly to a predetermined height from the inside surface of the outlet and extend from the cooling channel to the outer surface, in an arrangement of at least one protrusion formed on an inside wall of the outlet or on each of two opposing inside walls of the outlet. |

Turbine stator vane and/or turbine rotor vane with a cooling flow adjustment feature and corresponding method of adapting a vane
A turbine stator vane or turbine rotor vane has a body, a channel being adapted for leading a cooling fluid through the body, and a flow adaption feature protruding from the body to the channel in such a manner as to reduce a cross-sectional area of the channel. |

Gas turbine blade and manufacturing method
A blade for a gas turbine is described, the blade comprising a trailing edge and a trailing edge cooling channel extending from a first upstream end to a second downstream end, in which the width of the trailing edge cooling channel in the direction perpendicular to the camber line of the blade varies and the narrowest width in the trailing edge cooling channel is at the first upstream end, so as to provide a blade where the trailing edge can be removed with a minimal change or no change in the cooling flow capacity through the trailing edge cooling channel. Related methods are also described. |

Gas turbine engine airfoil frequency design
A turbomachine airfoil element includes an airfoil that has pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 0.75-0.85 inch (19.1-21.6 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span and is in a range of 0.56-0.66 inch (14.2-16.8 mm). The airfoil element includes at least two of a first mode with a frequency of 2740±10% Hz, a second mode with a frequency of 5956±10% Hz, a third mode with a frequency of 6554±10% Hz and a fourth mode with a frequency of 31959±10% Hz. |

Rock anchor inflation and draining system
Rock anchors, inflation chucks, and inflation systems such as those described herein, allow for substantially complete draining of fluids from interior volumes of the rock anchors. In various situations, corrosive fluids may be introduced to the rock anchor, including inflating the rock anchors and during normal use, such as by groundwater intrusion. The inflation chucks described herein include multiple inflation paths for more effectively introducing and draining fluid from rock anchors during inflation processes and during general use. |

Pumpable resin system
A rock bolt system includes a fitting including a main body defining a central opening configured to receive a rock bolt and a grout body defining a space between the main body and the grout body, with the main body defining a grout opening in fluid communication with the central opening. The main body is rotatable relative to the grout body, with the grout body defining a resin port and a catalyst port. The resin port and the catalyst port are in fluid communication with the space and the grout opening of the main body. The system further includes a rock bolt defining a central opening, with the central opening of the rock bolt configured to be in fluid communication with the central opening of the fitting when the rock bolt is secured to the fitting. |

Characterizing a wellbore depth interval from rock fragments
Methods and systems for characterizing a wellbore depth interval from rock fragments, including a method that includes converting measurements of a bulk rock fragment sample and of individual rock fragment samples to a concentration percent, computing a normalization deviation for each of the individual rock fragment samples relative to the bulk rock fragment sample (said normalization deviation being derived from the concentration percent of the bulk and individual rock fragment samples) and ranking the individual rock fragment samples based on a corresponding normalization deviation. The method further includes selecting one or more individual rock fragment samples based on a corresponding ranking, characterizing the properties of the wellbore depth interval from which the bulk and individual rock fragment samples originated using measured properties of at least some of the selected individual rock fragment samples and presenting to a user the characterized wellbore depth interval. |

Dual rotor pulser for transmitting information in a drilling system
A rotary pulser for transmitting information in a mud pulse telemetry system of a drilling operation. The pulser has two rotors mounted adjacent each other so that obstruction of the passages formed between the blades in one pulser by the blades of the other pulser creates pressure pulses in the drilling fluid. Each rotor is separately controlled and can be rotated continuously in one direction or oscillated. The ability to rotate each rotor separately provides flexibility in the pulser's operating mode, so as to allow more efficient generation of pulses, and also enhances the ability of the pulser to clear debris that would otherwise jam or obstruct the pulser. |

Systems and methods for reducing electrical interference in measurement-while-drilling data
Systems and methods are presented for reducing electrical interference in measurement-while-drilling (“MWD”) data. An example may include, among other features a MWD data acquisition system including an analog data reception for receiving analog MWD data, an analog-to-digital conversion circuit, at least one isolation circuit for electrically isolating the analog data reception circuit and the analog-to-digital conversion circuit from a digital data transmission circuit. In some implementations, the data reception device may be at least partially powered by the battery. |
