  • Patent number: 6341767
    Abstract: A spring system includes an axially moving center attachment located between two static attachments. Bi-directional axial center deflections cause push-pull restoration forces. There is little mechanical fixturing preload stress acting on material also subjected to high cyclic stresses. The spring material includes an unbroken path between the two static attachments, going through the center attachment. In one embodiment, the unbroken path is a length of wire bent into substantially parallel side-by-side helices clamped statically at the bottom of each helix. A moving attachment grips the center of the wire bridging diagonally between the tops of the helices. In a second embodiment, the unbroken path is a length of wire bent into end-to-end helices sharing a common axis and clamped statically at the axially opposite ends of the spring.

The apparatus further has a pair of spring retaining members for supporting the both ends of the spring body, and a rotary member rotatable provided around the central axis of the spring body as a center at least one one spring retaining member. At least one of the elastic longitudinal beam member is provided at one end of the rotary member. This spring apparatus is a tightly wound coil and made of the elastic longitudinal beam members in fully compressed state. When extended, each elastic longitudinal beam member is sequentially spirally deformed at larger pitch from the end. The twisting deformation of the elastic longitudinal beam member is released by rotation of the rotary member.

  • Patent number: 4848757
    Abstract: An improved remote center compliance (RCC) device having translational and rotational compliance. The RCC device includes at least two spaced monolithic members having a common axis extending therethrough. Adjacent pairs of monolithic members are interconnected by a stage including at least three discrete coil springs spaced about the axis of the monolithic members. Each spring is axially extensible and laterally deformable for providing both rotational and translational compliance about a center of compliance. The improvement includes providing coil springs that are at least partially coil-bound to increase the ratio of axzial stiffness to lateral stiffness of the springs and increase the projection of the center of compliance away from the RCC device.

  • Patent number: 4832321
    Abstract: The invention herein is a coil spring assembly for the suspension of a vele including a series of plates whose tapered edges protrude between the coils of the spring. The plates are slideably mounted on bolts parallel to the longitudinal axis of the spring, the bolts being moveable toward or away from the longitudinal axis of the spring. The resulting movement of the plates toward or away from the spring causes a thicker or thinner zone of the tapered edge of the plate to be disposed between the spring coils, thereby changing the degree to which the plates stiffen the spring.

  • Patent number: 4830345
    Abstract: A cushion comprising two seat pieces combined with inside faces facing towards each other, and a plurality of coil spring members which connect the two seat pieces. Each of the seat pieces is a shallow circular plate having a smooth central concavity and includes internally a series of concentrically extending walls, a series of radially extending walls, and a plurality of appropriately spaced tubular walls with an upstanding cylinder formed inside. Each of the coil spring members is closely coiled at its two terminals and encompasses corresponding cylinders of the two seat pieces.

  • Patent number: 4728087
    Abstract: Adjacent the rigidly anchored end of a vertical coil spring, which carries out transverse oscillations, the spring is subjected to considerable breaking forces which limit the lifetime of the spring. At least one abutment is provided to cooperate with a spring portion slightly spaced from the rigidly anchored spring end such that this spring portion is permitted to carry out only a limited vertical movement, whereby the breaking influence on the spring is largely reduced.

  • Patent number: 4692907
    Abstract: A gradiometer array of two or more sensors consists of a closed housing filled with a volume of fluid having a desired specific gravity. The sensors are freely suspended in the housing by flexible tethers. The sensors have different specific gravities such that one always sinks and the other floats. By that means, the sensors are self-aligning along an axis parallel to the gravitational vertical.

  • Patent number: 4613119
    Abstract: A suspension device for suspendingly supporting loads under a generally constant spring-biasing support force defined by two relatively movable portions, a first of the portions being secured to a support and a second of the portions being secured to a load to be suspendingly supported thereby, a main spring for biasingly mounting the first and second portions relative to each other, the second portion being an elongated member having an upper end portion, at least one compensatory spring adjacent the upper end portion of the elongated member, a pivoted lever between the one spring and the elongated member upper end portion, and a cam and cam follower carried by the lever and its elongated member upper end portion which compensates the tension and/or compression forces of the main spring as the cam and cam follower operate relative to each other.

  • Patent number: 4497500
    Abstract: An animal-simulating child's ride-on toy has head and foreleg members that are capable of being turned independently of the body, and has a unique suspension system that is accommodated in the body without disfiguring structure, thereby enhancing the lifelike appeal of the toy. The construction consists of relatively few parts which can be assembled with desirable ease, and production is relatively facile and inexpensive.

  • Patent number: 4400186
    Abstract: A constant tension device is provided for use with a filter bag. The device includes a spring and a linkage assembly for applying tension to the filter bag. The linkage assembly is designed such that a substantially constant tension is applied to the bag regardless of the force exerted by the spring. A pair of lever arms is included within the linkage assembly for applying pressure to a bag cap if the device is used within the filter bag.

  • Patent number: 4269661
    Abstract: A top nozzle for a nuclear reactor fuel assembly which includes an orifice plate designed to receive control rod guide tubes extending upwardly from the top of the fuel assembly. Nozzle pin extensions connected to the orifice plate are axially coextensive with the guide tubes and project upwardly through a top nozzle hold-down plate, and through openings in the upper core plate in the reactor. The hold-down plate is spring biased into an upper core plate engaging position and since the pin extensions are adapted to move in the core plate and against the action of the springs, the top nozzle thus becomes effective in accommodating upwardly acting hydraulic forces which tend to lift the fuel assembly, and to accommodate differential expansion of parts in the fuel assembly as compared to the core barrel in which the assembly is located.
