International Classification:

F16K 43/00

US Classification:

137 1518, 13731501

Abstract:

A plumbing fixture trim snap connect comprises a faucet handle assembly and a base assembly. The faucet handle assembly includes an escutcheon bearing upper and lower internal tabs, freely rotatable around a faucet handle. The base assembly includes a base seat on which a spring and retainer are maintained in an upwardly biased position. The seat includes a groove and helical cut, and the retainer includes indents in its surface to accommodate the upper and lower tabs of the escutcheon. By pushing the escutcheon down atop the base assembly and rotating the escutcheon relative to the base assembly, the apparatus can be assembled. Disassembly can be accomplished simply by rotating the escutcheon in the opposite direction.

International Classification:

B64F 1/10

US Classification:

180 67

Abstract:

An improved aircraft towing vehicle includes a base plate, a controller and two drive motors supported by two track assemblies. A pivoting wheel constraint mechanism rests on the base plate and includes a front roller mount, a rear roller mount and a linkage connecting the front roller mount and the rear roller mount. When the rear roller mount is pushed or otherwise urged backward, the linkage causes the front roller mount to pivot upward to confine an aircraft wheel on the base plate. A latch keep is also connected to the base plate for holding the rear roller mount in the backward position and locking the wheel constraining mechanism for moving an aircraft.

US Patent:

Filed:

May 12, 1995

Appl. No.:

8/440198

Inventors:

Kenji A. Kingsford - Devore CA
Anthony K. Chan - San Gabriel CA

Assignee:

Furon Company - Laguna Niguel

International Classification:

G01L 700

US Classification:

73706

Abstract:

A double-diaphragm gauge protector constructed according to principles of this invention comprises a diaphragm housing formed from a upper housing body, a lower housing body, and a central housing body interconnected between the upper and lower housing bodies. A first diaphragm is disposed within the upper housing body forming an upper chamber therebetween and a liquid pressure-transfer medium is disposed within the upper chamber. The first diaphragm includes a transfer pad that projects outwardly away from a frontside or downwardly facing bottom surface of the first diaphragm toward the lower housing body. A second diaphragm is disposed within the lower housing body forming a lower chamber therebetween. The second diaphragm also includes a transfer pad that projects outwardly away from a frontside or upwardly facing top surface of the second diaphragm toward the first diaphragm. The transfer pads of the first and second diaphragms are positioned one on top of the other.

Filed:

Jun 23, 1989

Appl. No.:

7/372444

Inventors:

Kenji A. Kingsford - Devore CA
Anthony K. Chan - Alhambra CA

Assignee:

Osmonics, Inc. - Minnetonka MN

International Classification:

F04B 4502

US Classification:

417473

Abstract:

A bellows-type pump having a support ring positioned interiorly within the coil of the plastic bellows. The support ring is initially coiled to a diameter smaller than the normal bellows coil diameter. The free ends of the support ring have a telescopic relationship so that, when expanded to form a complete loop for supportive engagement within the bellows coil, the oppose free ends of the loop circumferentially engage one another and are positively held in telescopic engagement due to the circumferential hoop stress of the support ring.

Assignee:

Osmonics, Inc. - Minnetonka MN

International Classification:

F04B 4306
S18E 5410

US Classification:

417 63

Abstract:

A bellows-type pump has a plastic bellows interiorly supported by interior pressure. The interior pressure is supplied by a fluid source which passes through a pressure regulator to control the amount of interior pressure exerted on the bellows. A fiber-optic leak detector can be inserted into the plastic bellows to detect the leakage of process fluid therein.

Appl. No.:

17/368839

Inventors:

Anthony Chan - Sierra Madre CA, US
Tracy Haeggstrom - Orange CA, US

International Classification:

B64F 1/22

Abstract:

A helicopter tug apparatus for loading, transporting, and unloading a helicopter landing skid includes a plurality of landing skid loading units. The loading units are arranged to support the landing skid, and each of the loading units includes a skid cradle with a plurality of tug rollers configured to engage the landing skid. The loading units each include a drive track, and at least one motor for operating the skid cradle and the drive track. The rollers are reverse synchronized with the drive track, such that when the drive track moves the loading unit under the landing skid, the tug rollers turn in reverse to avoid placing lateral force on the landing skid.
