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.

Abstract:

Nonwoven fiber webs are produced by spraying one or more aqueous binder formulations containing one or more polymers selected from the group of vinyl ester polymers and (meth)acrylic ester polymers, and in a separate step, spraying one or more aqueous silicone formulations containing one or more polysiloxanes, onto the surface of an airlaid nonwoven.

International Classification:

Abstract:

Defoamer compositions contain a) a two-stage hydrosilylation product of one or more MQ or MTstarting materials with a hydrosilylatable composition containing α-methylstyrene, and then with a linear or branched organopolysiloxane bearing at least two hydrosilylatable groups; b) a silicone resin; and c) silica. The defoamers are particularly useful in machine laundering and dishwashing compositions.
