摘要： In order to provide simpler manufacture and lift up and blow down control, leaf elements are provided which have profile edges arranged to associate with each other in order to create a ring carousel, either about the front or rear edge of a leaf seal arrangement. In such circumstances gas flow through the leaf seal arrangement encounters the profile edge in order to adjust leaf section position for appropriate sealing efficiency.

摘要： Leaf seal arrangements 1 are known in which a number of leaf seals 2 are presented in a housing 3 in order to create a seal relative to a rotating surface 4. Conventional arrangements 21 have the leaf seals 2 aligned with an axis of rotation for the rotating surface 4, there is symmetrical lift up and blow down of a tip end 5 relative to the surface 4. In such circumstances the arrangement 1 is dependent upon the seal 2 stiffness to achieve designed operational performance. By presenting leaf seals 22 at an askew angle relative to an axis of rotation RR asymmetric deflection is achieved between an inlet side 30 and an exit side 31 such that the inlet and exit flow areas change and therefore lift up/blow down forces can be controlled to achieve a more optimal positioning of a tip end 25 relative to a rotating surface for operational performance with reduced risk of wear upon the leaf seals 22.
摘要翻译：叶密封装置1是已知的，其中多个叶片密封件2呈现在壳体3中，以便相对于旋转表面4形成密封。常规布置21具有与旋转轴线对准的叶片密封件2用于旋转表面4，相对于表面4存在尖端5的对称提升和吹除。在这种情况下，布置1取决于密封件2的刚度以实现设计的操作性能。通过以相对于旋转轴线的倾斜角度呈现叶片密封件22在入口侧30和出口侧31之间实现不对称偏转，使得入口和出口流动面积改变，因此可以控制升降压力以相对于旋转表面更好地定位尖端25以便操作性能降低，同时降低叶片密封件22的磨损风险。

摘要： A first process is provided for forming a stack of leaves for use in a leaf seal which effects a seal between two components. Corresponding processes are provided for forming a leaf-spacer pair and then for forming a stack of leaves from such pairs. Each leaf of the stack has a leaf section which maintains wiping contact with one of the components and a root section which is fixed relative to the other component and from which the leaf section extends. The stack includes a plurality of spacers which interpose between the root sections.

摘要： The benefits of leaf seals with respect to providing sealing in gas turbine engines is well known but wide scale applicability is hindered by the costs and manpower necessary for assembly of leaf seals. By utilising a concertina fold of a band or strip 50, 80 in which leaf seal elements 51, 52 are defined with leaves seal sections 52, 82 and spacers 53, 83 defined at tilt angles appropriate for the eventual lay angle in a leaf seal assembly more automated manufacture of leaf seal assemblies is achieved. The means by which the leaf seal sections 51, 81 are formed ensures that the spacers 53, 83 have a thickness greater than the leaf seal element 82a and generally side portions are provided with folding sections 56, 86 which are sacrificially removed during forming of leaf tufts 140 for final assembly within leaf seal assembly 1.

摘要： It has been found that stress in X-ray transparent films used to form masks for X-ray lithography also cause distortions of the film and of the high-resolution X-ray-absorptive pattern formed thereon. A method is disclosed which anneals boron nitride films for use in X-ray masks in such a way as to control stress.

摘要： A deflection wedge is positioned in a long horizontal drill hole by securing it with a shear pin to an extension on a drill string. The extension is turned independently of the drill string to enable a droparm mechanism to actuate a trigger which stops rotation at a predetermined orientation. Rotation is effected by means of a rifle bar mechanism. The rifle bar presses against the bottom of the hole to cause rotation and the trigger declutches the rifle nut when the droparm drops.
