  • Patent number: 7303185
    Abstract: A damping arrangement or isolator has two terminal members which are connected with each other by a single closed-loop cable band arrangement serving as a damping member. The terminal members each possess at least two eyes to receive the cable strap in the open position of the eyes and means for clamping the cable strap by closing the eyes, said cable strap extending in an alternating fashion from one eye of the one terminal member to an eye in the other terminal member. Accordingly an extremely rapid and simple assembly of the damping arrangement is possible and very even resilient and damping properties are ensured.

    Abstract: An impact absorber for protecting a protected item against damage or injury upon impact includes a formed metallic structure having at least one Nitinol member having a grounded portion in contact with a first structure positioned to engage the protected item, and an impact receiving portion. In one embodiment, the formed metallic structure includes a plurality of Nitinol wires connected together at opposite polar regions in the form of a wire-frame sphere. The wires in the wire-frame sphere may be superelastic austenitic Nitinol in a strained condition. A release device holds the wire-frame sphere in a collapsed condition and may be actuated to release the strained superelastic Nitinol structure to a deployed position at which the deployed superelastic Nitinol structure is positioned to engage and absorb energy from the protected item impacting the impact absorber.

  • Publication number: 20020063368
    Abstract: The present invention discloses a fluid-free mesh bearing damper, e.g., for a flywheel energy storage device. The disclosed mesh bearing damper is uniquely suitable for use in combination with flywheel assemblies, which typically are evacuated by one or more pumps to create a vacuum to substantially minimize energy loss due to air friction, because, among others, the disclosed bearing damper does not use fluids, e.g., pressurized oil, that may affect deleteriously the operation of the pumps. Moreover, the disclosed bearing damper damps vibrations, i.e., reduces the amplitude of the vibrations, induced by the rotating shaft, deflection of the shaft, and/or by the misalignment, or eccentricity, of the shaft; substantially lowers the load on the bearings, which enhances the life of the bearings and facilitates magnetic levitation; and transfers heat away from the bearings, which, further, enhances the life of the bearings. The disclosed bearing damper comprises at least one, e.g.

  • Patent number: 6299150
    Abstract: A spring element is made of a spring material and is formed into a generally elliptical shape. Two mounting pins extend in a normal direction through parallel relatively short segments of said elliptically-shaped spring element. The mounting pins are substantially aligned with the shorter of the two axis of the elliptically-shaped spring element so as to extend both inwardly and outwardly of said elliptically-shaped spring element. An elastomeric coating is applied around substantially all of the spring elements and a pair of blocks, each of which surrounds one of the mounting pins receives one of the mounting pins. A number of spring elements are joined together by two parallel, spaced-apart coupling links which contain cavities therein to receive one of the blocks of each of the spring elements.
