  • Publication number: 20140265077
    Abstract: Elastomeric bearings exhibit a reactive positive spring effect, i.e., they produce an opposing torque or force when angular displacement or translation is applied upon them, due to shear stress developed within their elastomer parts. The present invention incorporates a device that exhibits an increasingly strong torque or force in the same direction as the displacement, i.e., a negative spring, under similar conditions of movement. When properly calibrated, the subject type of device can be used in paralleled motion with the ordinary reactive elastomeric bearing to produce a combined effect in which at least a part of the torque or force of the elastomeric bearing is changed or minimized over a range of movement.

    Abstract: An improved runner for use with a SAILRAIL hydrostatic bearing levitation system is disclosed. The runner uses a substantially solid core having a degree of flexibility in a vertical plane, a thin pad of flexible, compliant material extending transversely around the core, and an outer flexible, compliant sheath enclosing the pad and the core. Flexibility is enhanced by a longitudinally extending slot cut into the core from the upper surface thereof. The side walls of the core are flat and straight and meet the lower convex surface of the core at a generally sharp longitudinal edge. Also the ends of the runner can angle upwardly to enhance the ability of the runner to traverse joints, gaps, or imperfections in the SAILRAIL rail. The runner can be secured to a deck member and provides specific advantages over prior art runners which had a larger profile, were more expensive and were not as efficient as the low profile runner of this invention.

  • Patent number: 4801019
    Abstract: A shock absorbing spring device (A,C) is illustrated which includes a plurality of elongated, slender spring elements (B). The device may also include a central shock absorbing unit (10). Spring elements (B) comprise fiber reinforcing strands (32) embedded in the matrix material (31). Spring elements (B) have a contoured profile which includes a thickened medial bend (38) and a reverse bend (44) formed at ends (34,36). In this manner, spring elements (B) deflect outwardly from their longitudinal axis in a reliable manner when ends (34) and (36) are loaded with compression. In one embodiment of the device (A) spring elements (B) are arranged to deflect radially with respect to longitudinal axis (37) of the device. In another embodiment (C) medial portion (38) of spring elements (B) deflect circumferentially in a row about longitudinal axis (43) of the device.

  • Patent number: 4781363
    Abstract: A vibration isolator is formed with a spring mechanism and a fluid transmion mechanism interposed between a vibrating member and a support member. The fluid transmission mechanism includes a primary fluid chamber and a secondary fluid chamber, with the secondary fluid chamber being deformed to a greater extent than the primary fluid chamber as a result of vibrations. An inertia mass operatively associated with the secondary fluid chamber is displaced as a result of vibrations and is thereby accelerated with a resulting inertia force causing fluid pressure change in the fluid transmission mechanism which compensates as a dynamic force the dynamic portion of the spring force transmitted from the spring mechanism to the support member.

  • Patent number: 4778159
    Abstract: A range spring assembly for a differential pressure responsive device which includes a spring retainer plate configured for coaction with a movable portion of a device, such as a bellows or diaphragm. A flat spiral spring in spaced relation to the retainer plate is provided with a clamp disc. A plurality of helical range springs are equiangularly disposed about a circumference inwardly of the periphery of the retainer plate, each of the range springs having a first end thereof securely attached to the retainer plate adjacent the center thereof, with the other ends being selectively attachable to the clamp disc, whereby the range may be readily established by locking one or more ends of the helical springs for providing the desired spring bias for the selected range.

  • Patent number: 4687079
    Abstract: A fluid levitated generally convex support member particularly useful in supporting a pallet, plate or belt such that the pallet, plate or belt load may be moved in an air powered track system, the system including at least one concave track with means for supporting and guiding the convex member and the pallet, plate or belt thereabove on a thin film of pressurized air jetting from nozzles in the track. The support member includes a generally tubular, flexible and partly deformable outer member and means for internally stressing the outer member so that under load there will be controlled deformation thereof. The deformed member will be closely complementary to the track surface to maximize load carrying capacity while minimizing fluid support power requirements and the detrimental effect of track deformities.

  • Patent number: 4579320
    Abstract: Improvements to the various components of hydrostatic bearing levitation systems, systems wherein fluid pressure between a load and the rails of a track system supports and guides the load, are described. The rail has a plurality of lengthwise extending ports and nozzles communicating from the innermost ports through the curved upper wall to the interface area between the rail and the load. The nozzles are arranged in longitudinally aligned groups and in a pair of parallel rows with the groups of one row being longitudinally staggered with respect to the groups of the other row. The nozzles can be inexpensively produced by boring an oversize hole through the upper wall and fixing a cannula, such as a hypodermic needle, in the bore. The cannula's internal diameter is the desired nozzle diameter. The load support member has a compliant outer cover, a central core, and a filler material wound tightly on the core.

  • Patent number: 4518154
    Abstract: A pneumatic spring for motor vehicles which includes a closed spring volume and two spring surfaces of different sizes adapted to be subjected to pressure acting in opposite directions. The two spring surfaces each have an effective spring surface which is variable in size as a function of travel of the pneumatic spring. A separate support arrangement is provided for each of the spring surfaces for supporting the spring surfaces so as to be coaxial with respect to one another. A linking construction is provided for elastically linking the two support arrangements with one another so as to enable an axial distance between the support arrangements to be variable within predetermined limits as a function of a pressure of the closed spring volume.

  • Patent number: 4331041
    Abstract: A motion transmitting remote control assembly of the type for transmitting forces along a curved path by a flexible motion transmitting core element movably supported in a flexible conduit. The assembly includes a support member adapted to be connected to a support structure (such as a bulkhead) and the conduit includes a slider member slidably disposed in a passageway extending longitudinally through the support member. The support member includes a transverse guideway in which is disposed a metal L-shaped latch member having an aperture in one leg through which the slider member extends. A coil spring reacts between the support member and the other leg of the latch member for biasing the bottom of the aperture into engagement with the slider member. The bottom of the aperture in the latch member has a tooth which coacts with ratcheting teeth on the slider member.

  • Patent number: 4245826
    Abstract: A column which includes an elongated guide tube receiving a pneumatic spring of the piston-and-cylinder type in its bore. A bar is fixedly fastened to the piston rod member or the cylinder member of the spring in longitudinal alignment and extends in the guide tube bore from the associated spring member toward one of the two longitudinally terminal parts of the guide tube. A spring assembly extending about the bar is interposed between spring seats on the pneumatic spring member fixedly fastened to the bar and the one terminal part of the guide tube. Cooperating abutments on the bar and on the one terminal part of the guide tube limit movement of the bar toward the other longitudinally terminal part of the guide tube.
