  • Patent number: 9637041
    Abstract: The present invention comprises an apparatus for use in line with a chain or a strap tie-down assembly. When the chain or strap tie-down assembly is tightened on a commodity to prevent movement of the same during shipping, the apparatus compresses and stretches. During transport, if the commodity loosens and creates slack in the chain or tie-down assembly, the apparatus may decompress and shorten, thereby taking up the slack and maintaining tension in the chain or tie-down assembly to prevent or minimize loosening and damage of the commodity.

  • Patent number: 9531178
    Abstract: An overhead wire tension balancer can prevent rotation of an inner cylinder connected with an overhead wire, without deteriorating rotation preventing function, even if stroke is increased, and does not complicate production steps. A rotation preventing plate is formed at the inside of an inner cylinder, and an opening which cannot rotate relative to the rotation preventing plate and which can relatively move in a condition which passes a long plate, is formed on the rotation preventing plate. The long plate is formed by two long plate pieces in an L shape in which a tip is bent, a hanging portion is formed by this bent portion and prevents the rotation preventing plate from disengaging from the long plate.

Hyperelastic properties are inherent in the single crystal as formed: no cold work or special heat treatment is necessary. Alloy components are Cu—Al—X where X may be Ni, Fe, Co, Mn. Single crystals are pulled from melt as in the Stepanov method and quenched by rapid cooling to prevent selective precipitation of individual elemental components. Conventional methods of finishing are used: milling, turning, electro-discharge machining, abrasion.

Two sets of the springs can be arranged for biasing the rod member to a central position relative to the housing.

  • Patent number: 6371498
    Abstract: The present invention is for a device for mounting of wheels so that they may move in a preferably vertical direction at right angle to the wheel shaft. The invention is also standing board for prams having such wheel mounting. At its from end the standing board has a mounting means by which the standing board is pivotably mounted to the rear axle of a pram the main direction of movement of which is shown by arrow. The turning shaft of the wheel is mounted in a movable sleeve the movements of which are controlled both by a brushing which surrounds the sleeve and by a tube which is partially inserted into a groove in the sleeve. A spring is placed into the groove in the sleeve so that the spring contacts both the bottom of the groove and the end of the tube which penetrates the groove.

  • Patent number: 6345814
    Abstract: An accordion spring that replaces traditional coil springs in suspension systems. The accordion springs are made of a fiberglass composite and can be designed to have a linear or progressive spring rate upon compression. To achieve a linear spring rate, the shape of the accordion spring is symmetrical with both the top and bottom surfaces of each of the plurality of central regions of the spring are flat, wherein contact between the upper and lower surfaces of adjacent central regions will not occur until the accordion spring has bottomed out. A series of complementary bent regions are introduced to the spoked regions of the accordion spring that varies the spring rate of the spring as the spring is compressed. The accordion spring can be manufactured using a three-dimensional weaving process and offer improvements in weight reduction, mass reduction, packaging space reduction compared to traditional steel coil springs.

  • Patent number: 6336626
    Abstract: An improved stirrup suspension utilizes a multi-stage spring suspension to accommodate the different downward forces generated during normal riding as well as jumping. The stirrup suspension includes a housing having a bottom wall and continuous side wall, a slide member slidably received within the housing, a stirrup connector mounted to the lower end of said slide member, a first spring element received around the slide member, and a second spring element also received around said slide member. The first spring element is effective for exerting a force F1 under a minimum load while the second spring element is effective for exerting a force F2 that is greater than F1 under a minimum load. In use, the lower end of the slide member is attached to the stirrup which will move up and down relative to the housing. The slide member slidably moves within housing where a flange member at the top of the slide compresses the first and second spring elements upon the exertion of a downward force on the stirrup.

  • Patent number: 5398916
    Abstract: A metallic damping body for damping shock-type and/or periodically changing stresses, consists of a shape-memory alloy material for effecting the damping. In order to be able to achieve a high damping effect even under a high mechanical stress on the damping body, the shape-memory alloy is selected such that it is in a state of austenitic microstructure at the operating temperature of the damping body. A sufficiently high mechanical prestress is applied to the damping body so that the damping working range is within the range of the pseudoelastic strain which starts below the proportionality limit in the stress/strain diagram of the shape-memory alloy. When the damping body is compressively stressed, a multiplicity of closely adjacent, small, uniformly distributed voids are present in the interior thereof, which together make up at least about 5%, preferably about 15 to 40%, of the total volume of the damping body.
