Patent number: 5996632Abstract: A pressure relief adapter includes a body and a slideable sleeve positioned in a passageway thereof and cooperating therewith and with O-rings to define a sealed chamber containing ambient air or other gas. The slideable sleeve has an enlarged head at one end. A compression spring in the chamber urges the sleeve toward the end having the enlarged head. Upon introduction of hydraulic fluid under pressure into the passageway and sleeve, the hydraulic fluid acting on the enlarged head urges the sleeve in a direction compressing the spring and reducing the size of the chamber thereby relieving pressure in the fluid flow system in which the adapter is positioned.Type: GrantFiled: December 14, 1998Date of Patent: December 7, 1999Assignee: Aeroquip CorporationInventors: Todd J.

Patent number: 5960853Abstract: An apparatus for the accurate formation of a three-dimensional article comprises providing a first quantity and a second quantity of substantially uniform size droplets of a desired material wherein each droplet has a positive or negative charge. Each quantity of droplets is focused or aligned into a narrow stream by passing the droplets through or adjacent an alignment means which repels each droplet toward an axis extending through the alignment means. The droplets are deposited in a predetermined pattern at a predetermined rate onto a target to form the three-dimensional article without a mold of the shape of the three-dimensional article. The droplets of the first quantity and the second quantity are supplied at different distances, whereby the droplets of the first quantity bond to each other and the droplets of the second quantity do not bond to each other or to the first quantity of droplets.Type: GrantFiled: November 5, 1997Date of Patent: October 5, 1999Assignee: Aeroquip CorporationInventors: Robert A.

Patent number: 5924447Abstract: Valved couplers and gas processing components particularly suitable for ultra-high purity gas distribution for use in semiconductor manufacturing. In the couplers, a valve stem/bullnose seals the aperture of the coupler immediately adjacent the exterior of the coupler, so that only a minimal amount of the wetted surface of the coupler is exposed to the external environment. A gas processing component (e.g., a filter), or an entire integrated gas stick assembly, may be sealed from the exterior environment at both its inlet and outlet sides, by these valved couplers. As a result, the entire device can be purged after manufacture and left in a controlled environment during shipment and installation, reducing the need for purging after installation.Type: GrantFiled: June 26, 1998Date of Patent: July 20, 1999Assignee: Aeroquip CorporationInventors: Bryce Evans, Helen E.

Patent number: 5891212Abstract: Uniform sized and shaped spheres are formed by applying a minute periodic disturbance to a low viscosity liquid material. Pressure forces the material through at least one orifice in a crucible as a steady laminar stream. The stream enters an enclosed controlled temperature solidification environment which contains at least one heat transfer medium. A charging means is applied to the stream as the stream exits the crucible and breaks into a plurality of spheres to deflect the spheres as they pass through an electric field. The enclosed controlled temperature solidification environment cools and substantially solidifies the spheres.Type: GrantFiled: September 16, 1997Date of Patent: April 6, 1999Assignee: Aeroquip CorporationInventors: Jie Tang, Gary B. Hess, Mark D. Muszynski, Thomas S. Goehring

Patent number: 5799684Abstract: A frangible hydraulic fuse includes a fitting secured to a sleeve by a plurality of frangible pins. In normal operation, hydraulic fluid flows through the fuse through radial ports of a sleeve to which the fitting is engaged by the frangible pins. A compression spring urges a poppet slideably positioned in the sleeve to a position out of engagement with the radial ports. Upon rupture of the frangible pins, the fitting is released and hydraulic fluid may flow unimpeded through the radial ports creating a pressure drop which causes the slideable poppet to move to a position overlying and closing the radial ports.Type: GrantFiled: May 14, 1996Date of Patent: September 1, 1998Assignee: Aeroquip CorporationInventor: George B.

Patent number: 5787965Abstract: An apparatus for the accurate formation of a free-form three-dimensional article comprises providing a supply of substantially uniform size metal droplets of a desired material wherein each droplet has a positive or negative charge in an enclosed environment. The supply of droplets is focused or aligned into a narrow stream by passing the droplets through or adjacent an alignment mechanism which repels each droplet toward an axis extending through the alignment mechanism. The droplets are deposited in a predetermined pattern at a predetermined rate onto a target to form the three-dimensional article without the use of a mold of the shape of the three-dimensional article.Type: GrantFiled: September 8, 1995Date of Patent: August 4, 1998Assignee: Aeroquip CorporationInventors: Robert A.

Patent number: 5778928Abstract: An improved marine drain valve is disclosed. The valve includes a valve barrel having an intake opening and a discharge opening. A fluid passageway extends between the openings. A valve adaptor body surrounds the valve barrel and a torsion-compression spring is positioned between and attached to the valve barrel and the adaptor body. A vent passageway is defined by the valve for venting a reservoir to which the valve is attached. An operating pin extends outwardly from the valve barrel and is received for movement in a configured slot defined by the adaptor body. The slot has a first leg parallel to the valve barrel and a second leg extending perpendicular to the first leg. The spring urges the valve toward a nonoperating or locked position. To operate the marine drain valve, a user rotates the operating pin and forces it upwardly into the first leg of the slot thereby opening the valve. Upon release, the spring returns the operating pin to the locked position.Type: GrantFiled: July 12, 1996Date of Patent: July 14, 1998Assignee: Aeroquip CorporationInventors: John D. Boland, Gary M.
