Abstract: A seat assembly for a motor vehicle includes an air spring suspension system for effectively isolating the occupant of the vehicle's seat from shock, vibration and inertial forces directed along both a vertical axis and a horizontal axis. A stationary base plate member is attached to the floor of the vehicle and it supports a pivot linkage assembly joining the stationary base member to a movable base member. An air spring is disposed between the stationary base member and the movable base member to displace the movable base member in a generally vertical direction to an extent allowed by the linkage assembly. Supported atop the movable base member is a seat slide assembly that permits fore and aft adjustment of seat position within the vehicle. A vehicle seat mount is affixed to the pair of slide members and includes shock absorbing springs that are disposed between the slide members and the vehicle seat mount for cushioning inertial forces due to acceleration and braking.

Abstract: A "hot-pluggable" hard disk drive is mounted in a removable hard disk drive tray. The hard disk drive tray has a vibration dampening system for reducing vibration between the hard disk drive, the hard disk drive tray, and a hard disk drive docking bay located within a computer system. The vibration dampening system has three primary components. The first component is a strip of polymeric material located between an end of the hard disk drive tray and the docking bay. The second component of the vibration dampening system is a set of polymeric strips located between an inner surface of the tray and the hard disk drive. The third component of the vibration dampening system is a set of spring assemblies. Each spring assembly is located between the sides of the tray and the docking bay.

Abstract: An acceleration force isolator assembly for attaching a payload, such as a spacecraft or satellite, to a launch vehicle wherein axial acceleration forces on the payload are attenuated. The attachment includes an upper interface ring that is secured to the payload and a lower interface ring that is secured to the launch vehicle. Flexure of the upper interface ring provides axial compliance when axial acceleration forces are transmitted from the launch vehicle.

Abstract: A completely vented upholstered body of grid plates with a wave profile includes solid portions of the grid which pass through the wave extrema of its wave contour. Many of the solid portions of the grid preferably are disposed transversely to at least one wave propagation direction and, in each case, continuously over a large portion of a wavelength, at a distance from one another. There is only a limited, specified bending deformation, during which the solid portions of the grid can be deformed largely independently of one another as if they were individual spiral springs. As a result, the upholstered body has a high point elasticity despite the plate construction. By adroit dimensioning of the course of the wave thickness, an advantageous diffusion of stresses can be achieved without stress peaks. Moreover, the work of deformation is absorbed uniformly in the upholstered material. This results in a long service life of the upholstered body.

Abstract: A vertical seismic isolation structure is capable of achieving vertical seismic isolation of nuclear reactor components connected to each other by primary pipings, while suppressing the relative displacement with respect to the primary pipings. A nuclear reactor vessel, circulating pumps and heat exchangers, all of which are connected to each other by primary pipings in which a coolant is circulated, are mounted on a common deck. Vertical seismic isolators each of which has laminated large coned disc springs and is capable of expanding and contracting in only the vertical direction are installed on the top of a concrete wall surrounding the respective nuclear reactor components. The common deck is placed on all the vertical seismic isolators so as to support the entire seismic isolation structure (the common deck, the nuclear reactor components, etc.).

Abstract: A valve device for permitting a fluid to flow in two opposite directions at different rates includes an orifice body confining a flow passage. The orifice body has one end defining a valve seat. A valve member is swingingly mounted to the housing to move toward and away from the valve seat. The valve member has a hole with a cross-section smaller than that of the flow passage whereby the flow of the fluid is large when the valve member moves away from the valve seat and is small when the valve member moves toward and seats against the valve seat.

Abstract: A shock and vibration isolating device is provided for mounting a component on a supporting structure while absorbing with substantially equalized reaction force relative movement between the component and the supporting structure occurring in all of the three mutually orthogonal planes in which the dynamic loading of the component can occur. The device includes an open frame planar spring element lying in a plane parallel to one of the mutually orthogonal planes, the spring element composed of a core member of a low creep, high modulus, metal and a shell member of a plastic exhibiting high internal dynamic loss substantially encompassing said core. A first cantilever section adjacent a first end is mounted to the supporting structure; a second cantilever section parallel to the first cantilever section adjacent a second end is mounted to the component; and a bridge section connects the first and second cantilever sections and is perpendicular thereto.

This damping sandwich is placed at a joint in the machine tool between the cutting tip and a tool mounting area, and is shown as being provided between a mounting face of a tool mounting block and a mounting area. The damping sandwich permits greater depth of cut, with greater inches per revolution of chip removal without any chatter for improved metal removal.

Abstract: A two-dimensional (2-D) suspension system consists of series of rhomboidal parallel leaf springs (RPLSs) each of which comprises plural leaf springs apart from one another and at least two rigid walls for fixing both ends of the leaf springs at the same fixing angle selected not to be a right angle and to be different from fixing angles of other rhomboidal parallel leaf springs. Plural rhomboidal parallel leaf springs are linked in series by connecting the rigid walls in such a way that faces of all the leaf springs are perpendicular to an imaginary plane. The 2-D suspension system suspends a movable body which is allowed translation in a plane only and which is restricted in other motions. The mass of the rigid body connecting two RPLSs is so small that the resonance of the rigid body hardly interferes with the motion of the movable body. The 2-D suspension system can hold the movable body at both sides thereof in symmetry.

Abstract: A rocking chair of the type employing a flexure member formed of a flat, fiber reinforced material for supporting a chair seat with respect to a chair base in which the support means for supporting the flexible sheet member from the chair base has a flat surface to which the sheet member is secured and an aperture above the flat surface through which the sheet member extends, the opposed walls of the aperture diverging from top to bottom to allow flexing of the sheet member with the effective length of the flexure member decreasing as the chair is rocked rearwardly. The sheet member is preferably disposed at an angle to the vertical of between five and fifteen degrees, to impart an initial bias on the sheet member. The rear wall of the aperture is curved to allow a greater length of the sheet member to flex as the chair is rocked rearwardly.

Abstract: A muffler mounting (26) for a muffler (21) which is connected to an internal combustion engine (11) by a rigid exhaust pipe (16). Previous mountings for such mufflers have either been of the rigid type, which subjects the muffler to undesired stresses resulting from shock, vibration or thermal expansion, or have utilized flexible rubber belting hangers which deteriorate rapidly when subjected to high temperatures. The present invention provides a relatively thin, flexible, generally-vertical metal hanger (52) comprised of a plurality of thin, stainless steel, strips (53) overlaid on one another, to flexibly connect and support the muffler (21) to the engine (11) or frame (12). The present invention is particularly useful in vehicles wherein the engine (11) is resiliently mounted on the frame (12) and wherein the muffler mounting (26) is subject to high temperatures, corrosion, and oxidation.
