摘要： A shroud for surrounding a portion of a turbine flow path having improved cooling and durability is disclosed. The shroud includes a plurality of generally axial cooling holes spaced a substantially equal distance apart and a plurality of generally circumferential cooling holes oriented generally perpendicular to the generally axial cooling holes. The generally circumferentially cooling holes are spaced a non-uniform distance apart so as to provide cooling to selected portions of shroud sidewalls to lower shroud operating temperatures and improve shroud durability.

摘要： Aspects of the invention relate to a system for attaching a fuel swirler in a turbine engine combustor. According to embodiments of the invention, at least the axial upstream end of the fuel swirler can be attached to a combustor support frame using one or more fasteners, such as bolts. A radial bracket provided on the swirler to facilitate attachment. The axial downstream end of the swirler can be positioned within an opening defined in a swirler base plate or within an opening in a support plate. Aspects of the invention can reduce the time and cost associated with installation and replacement of fuel swirlers in a combustor while avoiding concerns associated with known welded pin attachment systems.

摘要： Bipolar lipids are described which are able to form complexes with polyanions. The lipids comprise a cationic head linked to a hydrophobic backbone and a hydrophilic tail and are capable of self assembly to form stable complexes in aqueous solutions. The lipids are of particular use for the delivery of bioactive substances such as nucleic acids to cells in vitro and especially in vivo.

摘要： A method and apparatus are provided for interfacing between a data source and a tightly-coupled memory. In the method and apparatus, a write data word and a write address are received from the data source and latched in a first clock cycle within a write buffer along a write data path, between the data source and the memory. The write data word is encoded according to an error detection code along the write data path. The write address and the write data word are applied to the memory from the write buffer. The write data word is accessible to the data source from the write data path or the memory beginning with a second clock cycle, which is a next subsequent clock cycle to the first clock cycle.

摘要： Bucket tip tenons requiring refurbishment are removed from the bucket tips by grinding. Groups of buckets are clamped on a rotatable table in positions adjacent an induction heating coil and a robotic welding arm, respectively. While one group is preheated, the other group of buckets is in a welding location, enabling the welding head on the robotic arm to sequentially apply weld buildup material to the bucket tips. After applying weld buildup material in multiple passes and sequentially to the bucket tips, the buckets are removed, stress-relieved and the weld buildup material machined to provide refurbished tenons. Upon removal of the buckets from the table, the table is rotated to locate the preheated buckets in welding locations and additional buckets are clamped to the table for preheating.

摘要： A double throw latch for a carrying case has a first elongated body, a first end of the body being pivotally mounted with one part of a carrying case. There is also a second elongated body that is pivotally mounted on the first elongated body. There is a first hook element on the first elongated body, and the first hook element is located towards a second end of the first elongated body. The first hook element is for engagement with a mating first formation on a second part of the carrying case. There is also an engaging element for engagement with a portion on the first elongated body. The area adjacent to where the second elongated body pivots with the first elongated body provides an inter-engaging surface or element for engagement with an opposite face on the first part of the case. After the second elongated body is toggled a predetermined amount from the closed position, the second elongated body engages the formation of the first elongated body. The first elongated body then separates from the mating first formation of the second part of the carrying case. It thereby disengages the first hook element from the mating first formation on the second part of the case. The first elongated body pivots relative to the first part of the carrying case at a position relatively close to the body of the carrying case.

摘要： A programmable gate array is disclosed for implementing asynchronous logic. In one embodiment, the array includes a set of cells, at least one of which includes a threshold gate having a plurality of inputs, an output, and a threshold value. Signals may assume an ASSERTED state having a logic meaning and a NULL state that has no logic meaning. The gate output switches to NULL when all inputs are NULL, and switches to the ASSERTED state when the number of ASSERTED inputs exceeds the threshold value. In the preferred embodiment, the gate exhibits hysteresis such that the output remains ASSERTED while the number of ASSERTED inputs remains greater than zero, and less than the threshold value. In an alternate embodiment, an array of simplified threshold elements is used to form more complex threshold gates.

摘要翻译： 公开了一种用于实现异步逻辑的可编程门阵列。 在一个实施例中，阵列包括一组单元，其中至少一个包括具有多个输入，输出和阈值的阈值门。 信号可以假设具有逻辑含义的ASSERTED状态和没有逻辑含义的NULL状态。 当所有输入为NULL时，门输出切换到NULL，当ASSERTED输入的数量超过阈值时，切换到ASSERTED状态。 在优选实施例中，门显示滞后，使得输出保持为ASSERTED，而ASSERTED输入的数量保持大于零且小于阈值。 在替代实施例中，使用简化阈值元素的阵列来形成更复杂的阈值门。
