    Abstract: A power transmission device includes a flywheel and a damper device. The flywheel includes a plurality of fixation holes. The damper device includes an input rotary member, an output rotary member, and a pair of first elastic members. The input rotary member and output rotary member each include a plurality of assembling holes disposed in corresponding positions to the plurality of fixation holes of the flywheel. The plurality of assembling holes are arranged in a circumferential direction such that two pairs of the assembling holes, each pair including two adjacent assembling holes, are each disposed at a larger interval than remaining assembling holes to produce a pair of accommodation spaces. A pair of first accommodation portions, accommodating the pair of first elastic members, is disposed radially outside the pair of accommodation spaces.

    Abstract: The sealing element for integration into a sealing tool for producing smooth stamping fields during the sealing of two plastic sheets has a base body. A first slot extends into the base body from a first narrow lateral surface, and a second slot, which is offset vertically from the first slot, extends into the base body from a second narrow lateral surface, in such a way that the two slots define a section of the base body which has substantially the shape of an S or reversed S. The first slot has a U-shape with a first leg of the first slot being longer than a second leg of the first slot, and the second slot has a U-shape with a first leg of the second slot being longer than a second leg of the second slot. Each of the two slots expands at its inner end to form a bore.

    Abstract: Vibration damping is important with regard to such components as hollow turbine blades in gas turbine engines. Traditionally damping has occurred through damping elements secured at the root or tip of such blades. Such damping is not optimised and results in potential problems with wear in operational life. By providing a tube of deformable material which can be located within a hollow cavity it is possible to provide an element which through friction engagement can absorb vibration energy and therefore damp such vibration. The tube incorporates a number of cuts and/or grooves in an appropriate pattern in order to define a deformation profile once the tube is expanded in location. The tube is secured in position internally upon an expandable element which is typically an inflatable device. Once in position the tube is retained in its expanded deformable profile and the engagement between the tube and the hollow cavity wall surface results in energy absorption through vibration episodes. It is also possible to provide a tube formed from a shape memory alloy which will expand of its own right in location to engage the hollow cavity wall surfaces for energy absorption during vibration episodes.

    Abstract translation: 振动阻尼对于诸如燃气涡轮发动机中的中空涡轮叶片的部件是重要的。 传统的阻尼是通过固定在这种叶片的根部或尖端处的阻尼元件发生的。 这种阻尼没有被优化，并且在使用寿命中导致潜在的磨损问题。 通过提供可以位于中空腔内的可变形材料管，可以提供通过摩擦接合可以吸收振动能量并因此减弱这种振动的元件。 该管以合适的图案包括多个切口和/或凹槽，以便一旦管在位置上扩展就能限定变形曲线。 管内部固定在可膨胀元件上，该可膨胀元件通常是可充气装置。 一旦就位，管被保持在其膨胀的可变形轮廓中，并且管与中空腔壁表面之间的接合导致通过振动发生的能量吸收。 还可以提供一种由形状记忆合金形成的管，其将在其位置上自身扩张以接合中空腔壁表面，以在振动发生期间吸收能量。

    Abstract: An impact and/or vibration absorbent material and articles, particularly a protective glove, making use of said material. An impact and/or vibration absorbent material of the present invention has at least two material layers. The individual layers of the impact and/or vibration absorbent material may be of the same material, or of different materials. Each material layer preferably contains a number of holes. The holes in one layer are located and arranged to be offset from the holes in an adjacent layer. The combination of inherent material properties and the inclusion and arrangement of holes renders such a material highly impact and/or vibration absorbent. When used in an impacting article, deflection of portions of one material layer into the holes in an adjacent material layer at impact further provides an enhanced transfer of impact force to an impacted object.
