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: A refrigerator with an ice dispenser includes a spiral type time delay unit for controlling the opening and closing of an ice duct. A duct cap opens and closes an ice duct formed in the refrigerator. A rotating shaft of the time delay unit is operably connected to the duct cap. Foldaway catching members on a rotating shaft intersect with a threaded cylindrical body. The catching members fold back to allow a quick opening of the ice duct. The catching members then interact with the threaded cylindrical body as the ice duct closes to delay the closing process.

Abstract: In a flywheel in which narrow portions to be engaged with a coil spring included in the flywheel are formed of recessed portions made by recessing the surface of a flywheel cover, the portions of a sensor plate welded to the front cover, which confront with the recessed portions are made more fragile than adjacent portions of the sensor plate. With this configuration, when the front cover is deformed, stress applied to welded portions adjacent to the recessed portions can be suppressed since the fragile portions are easily deformed. Accordingly, even if the recessed portions are formed to the surface of a flywheel cover, stress can be prevented from being concentrated on the coupling portions of the flywheel cover and the sensor plate.

Abstract: A twin flywheel (210) comprising first (211) and second (212) co-axially arranged flywheel masses which are mounted for limited angular rotation relative to each other. The flywheel masses (211, 212) are interconnected by at least one linkage arrangement (240), comprising a multi-link linkage (240) having two or more circumferentially spaced main links (242, 251) pivotally mounted on the second flywheel masses with the or each circumferentially adjacent pair of main links interconnect via a generally circumferentially extending connecting linkage, and an anchor link (242) which connects the multi-linkage (240) with the first flywheel mass. Relative rotation of the flywheel masses (211, 212) causes the multi-link linkage (240) to be pivoted relative to the second flywheel mass by the anchor link, so that when the twin mass flywheel is rotating, relative rotation of the flywheel masses (211, 212) is resisted by centripetal forces acting on the linkage arrangement. Any particular links may be in the form of a unitary link or in the form of a pair parallel plates. Associated with one or more links, or pivots or acting between the flywheel masses (211, 212) there may be controlling means to control the relative rotation of the flywheel masses (211, 212).

Abstract: There is provided an apparatus for developing a propulsion force in a predetermined direction. The apparatus includes an outer frame and an inner frame slidably mounted within the outer frame. The inner frame supports a flywheel which rotates about a shaft defining a first axis. Masses are mounted to the flywheel for rotational movement with the flywheel and for lateral movement relative to the flywheel in a direction to increase and decrease a distance of a center of gravity of the masses from the first axis. The outer frame supports a mass movement control member rotating with the flywheel about a second axis parallel to the first axis. The control member moves the masses cyclically such that the distance from the first axis is at a maximum in the direction of propulsion and at a minimum in a direction opposite to the direction of propulsion. A directional control controls the displacement of the outer frame in relation to the inner frame for controlling magnitude and direction of the propulsion force by adjusting the amount of offset between the first and second axes.

Abstract: A twin mass flywheel for a vehicle comprising two co-axially arranged relatively rotatable masses interconnected by a plurality of pivotal linkages. Each linkage comprises a first link pivotally connected to one flywheel mass, a second link pivotally connected to the other flywheel mass and a pivot joining the links to move radially outwardly. A resilient torque member in each common pivot operable after a predetermined rotation between the flywheel masses to resist said relative rotation. A variable hysteresis friction damping assembly, whose resistance to relative rotation changes as the relative angle of rotation is altered, acts between the flywheel masses. The damping assembly can be provided by two friction damping plates which operate at different stages of rotation. The relative rotation may be limited by a stop member on at least one of the flywheel masses which abuts an abutment surface on the other flywheel mass. The abutment surface can be resilient for cushioning abutment by the stop member.
