Patent number: 5529277Abstract: A system is described which utilizes two perpendicular four-bar linkages coupled by a common plate to provide a translational-free flexible suspension having two rotational degrees of freedom about a desired point. One of the four-bar linkages is secured to a stationary "ground" structure, and the other linkage is attached to the object to be supported, such as a mirror. In one embodiment, two links of each of the two four-bar linkages are constructed from spring steel flexure elements which are rigid in all directions except about the rotational axis. The flexure elements thus comprise "revolute joints". Because the flexure elements function as spring hinges, no friction is encountered when the suspension is displaced or "pivoted".Type: GrantFiled: September 20, 1994Date of Patent: June 25, 1996Assignee: Ball CorporationInventor: Miroslaw A.

Patent number: 5429338Abstract: An equipment mount for isolating equipment from shock loads and acoustic vibrations has a ring-shaped base mounted to a foundation. A generally cylindrical retainer has an X-shaped cross section and a pair of contact surfaces forming the X-shaped cross section and disposed at an angle relative to the axis of the retainer. The retainer is movable relative to the base. A generally cylindrical resilient member is disposed between the base and the retainer. The resilient member includes a kick segment at either end thereof projecting outwardly at an angle relative to the axis of the resilient member and having an end contacting one of the retainer contact surfaces when free standing. The resilient member is deformable under load so that a greater portion of at least one of the kick segments contacts at least one of the retainer contact surfaces to isolate the equipment from the load.Type: GrantFiled: August 11, 1993Date of Patent: July 4, 1995Assignee: Newport News Shipbuilding and Dry Dock CompanyInventors: Sam A. Runge, Han D. Phan

Patent number: 5407246Abstract: A seat for receipt of a child capable of providing exercise and entertainment comprising a seat having a rigid upper support and a lower support therebeneath and a circular bearing surface therebetween, the lower support having leg openings for passage of the legs of a child supported therein. An upper supporting tray has a radially interior opening in a circular configuration for receiving and supporting the seat, the upper supporting tray having a radially exterior periphery with projections extending downwardly therefrom. A bowl-shaped base is provided, the upper periphery of the base having spaced upstanding towers with openings depending from the upper ends thereof. Upstanding posts are also provided, each post having a lower end received within the upper end of a tower, each post having an upper end with a recess for receiving a downwardly depending projection.Type: GrantFiled: October 1, 1993Date of Patent: April 18, 1995Assignee: Lisco, Inc.Inventors: Paul K. Meeker, William R. Gibson, John C. Riedl

Patent number: 5280889Abstract: "A vehicle and the ballistic shock isolator therefor including a turret, a sensor assembly and a shock isolator isolating the turret from the sensor switch and including upper and lower annular members, a plurality of leaves secured at opposing ends thereof to the annular members, each of the leaves having a corrugated bellows shaped portion in the form of an even number of similarly shaped portions, alternate ones of the similarly shaped portions having an open end in opposing directions, each of the leaves varying in thickness and width in a direction from the upper annular member to the lower annular member. The variation in width of the portion is alternately from wide to narrow and then from narrow to wide in a direction from the upper annular member to the lower annular member.Type: GrantFiled: April 8, 1991Date of Patent: January 25, 1994Assignee: Texas Instruments IncorporatedInventors: David L.

Patent number: 5275371Abstract: A springy, low dielectric retainer device in the form of a rod, a triangle, an ellipse or whatever, is used in a compressed condition to hold RF energy absorber blocks in position juxtaposed "energy leaky" RF circuitry. The absorber blocks are held in position due to frictional forces provided by the compressed retainer. In this manner, the absorber blocks can be re-positioned to obtain optimum amplitude/frequency response characteristics from the affected RF circuit.Type: GrantFiled: January 22, 1992Date of Patent: January 4, 1994Assignee: Alcatel Network Systems, Inc.Inventors: Michael Brian, Larry D.

Patent number: 5267720Abstract: A structureborne noise isolator employs a two axis system whereby a noise generating platform is coupled to an inner frame by a first pair of diametrically positioned noise isolators, the inner frame being coupled to an outer frame by a second pair of diametrically positioned noise isolators. At least one noise isolator comprising a coil spring shrink fitted at one end to an inner housing and at the other end to a cover. The inner housing is inserted into an outer housing with a damping compound between and potted to the inner and outer housings. Additional damping compound is bonded to the base of the outer housing separating the base of the outer housing from the base of the inner housing. The cover, having damping compound bonded thereto, is coupled to the outer housing. A hub, positioned adjacent to the damping compound on the cover, is coupled to the inner housing.Type: GrantFiled: December 6, 1991Date of Patent: December 7, 1993Assignee: Sperry Marine Inc.Inventors: James R.

Patent number: 5249417Abstract: A method and apparatus to install and remove heavy components mounted on a base structure is disclosed. Various construction details are developed which provide means for coupling the component and base structure in a manner permitting relative rotation and translation about an axis of rotation. In one embodiment, an aircraft engine component (18) has a pair of hooks (32) and an aircraft engine (10) has a pair of pins (46) which engage the hooks to couple the component and engine to permit rotational and translational motion of the component relative to the engine. For this embodiment, a method for relative motion between an installed and uninstalled condition is comprised of maneuvering the component and engine between a coupled and uncoupled position, moving the coupled component relative to the engine about the axis of rotation, and manipulating a fastener means between a secured and unsecured position.Type: GrantFiled: September 25, 1991Date of Patent: October 5, 1993Assignee: United Technologies CorporationInventors: Paul W.

Patent number: 5042396Abstract: A plastic pallet in which an insert assembly is positioned within the hollow of the plastic pallet to discourage warpage and failure especially in racked, storage situations. The insert assembly comprises a pair of beams arranged in an X-configuration, tower members secured at their upper ends to respective ends of the beams and positioned respectively in the four corners of the pallet, and tensioning straps extending between the tower members around the perimeter of the pallet proximate the upper surface of the bottom wall of the pallet. The X-configured beams are positioned in the space between the spaced upper and lower sheets of the platform structure of the pallet and are maintained in a convexly bowed configuration by the tensioning straps so as to resist downward bowing of the platform structure, even when the pallet is racked for extended periods of time in a loaded condition.Type: GrantFiled: November 27, 1989Date of Patent: August 27, 1991Inventor: Lyle H.
