Appl. No.:

10/310184

Inventors:

Peter D. Honer - Neenah WI, US
Oliver P. Renier - Green Bay WI, US
Peter S. Lortscher - Neenah WI, US

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

G01G 19/56

US Classification:

73 108

Abstract:

A method of simulating a dynamic force event comprises rotating a cam about an axis according to a rotational speed profile and biasing a follower against a surface of the cam as the cam rotates so that the follower moves on the surface and imparts a braking force against the surface. The method further measures the braking force on the rotating cam with a measurement device operatively connected to the cam, the braking force varying according to the friction between the cam surface and follower moving against one another. In another aspect of the invention, a method of calibrating a testing machine measures a braking force resisting movement of a first body over time to produce a simulated dynamic force response of the first body and compares it with a standard dynamic force response to calibrate the testing machine.

International Classification:

G01L009/02

US Classification:

073/746000

Abstract:

Apparatus for generating a dynamic force response that simulates a dynamic force typically generated by an experimental event. A cam having a profile, such as a serrated profile, rotates about an axis according to a rotational speed profile. A braking device operatively connects to the cam, such as a follower biased against the cam, for generating a braking force resisting rotation of the cam. A measurement device measures the braking force on the cam to generate the dynamic force response.

US Classification:

604364, 428220, 428 352

Abstract:

A film that is both biodegradable and flushable, and yet can still act as a barrier to water or other fluids during use, is provided. More particularly, the film contains a water-dispersible core layer that helps the film to lose its integrity after being flushed, as well as a water-barrier skin layer that helps maintain the integrity of the film during use. The nature and relative concentration of the components in the water-barrier layer are selectively controlled to achieve a combination of different functions. That is, the majority of the polymers employed in the water-barrier layer are biodegradable polymers that can be degraded by microorganisms while in an aqueous environment (e.g., septic tank, water treatment facility, etc.). To even further enhance the overall renewability of the layer, a relatively high amount of the biodegradable polymers are starch polymers, which are also renewable. The starch polymers can also minimize the degree of stickiness in the film, which can sometimes result from certain types of synthetic polymers. Even at a high starch content, the present inventors have discovered that films may still be readily formed by using synthetic biodegradable polyesters in combination with the starch to facilitate melt processing.
