Appl. No.:

10/021229

Inventors:

International Classification:

G01B005/08

US Classification:

033/555100

Abstract:

A gage assembly to measure the diameter of a piece of tubing. The gage assembly is especially configured to take measurements during the extrusion manufacture of the tubing when an eccentricity in the outer diameter of the tubing is present. The gage assembly includes a pair of contact wheels mounted such that the space between them defines a path with a diamond-shaped cross section for the tubing to pass through. Each contact wheel includes cutouts that define a pair of planar contact surfaces that are angularly disposed relative to one another. As the tubing leaves the extruder, it axially passes through the diamond-shaped path, coming in contact with the planar surfaces of the contact wheels. The contact wheels are slidably and rotatably mounted such that translational movement imposed on the planar surfaces of the wheels due to eccentricities on the tubing outer surface are resolved into movement along a first translational direction, which is correlated to the size of the undulation in the tubing, then registered as output on an indicator. The angular positioning of the planar contact surfaces to one another permits the simultaneous measurement in two dimensions on the outer surface of the tubing, while the slidable mounting of the contact wheels ensures continued contact between both planar surfaces of each wheel and the tubing outer surface.

Appl. No.:

7/156688

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F17D 300

US Classification:

13762515

Abstract:

The invention concerns a system for distributing fluid pressure to several fluidic motors from a common location. At the common location, a source pipe, which acts as the source of fluid pressure, travels past, and couples with, each pipe in a group of receiver pipes in sequence. Pressure in the source pipe is controlled so that the pressure is proper for each receiver pipe with which the source pipe couples. The receiver pipes connect with fluidic motors. Accordingly, a single control apparatus, located near the source pipe, is used and the pressure and flow from the source pipe is time-multiplexed and transmitted to the fluidic motors.
