Atomically Polarizable Electrorheological Material

US Patent:
5294360, Mar 15, 1994
Filed:
Jan 31, 1992
Appl. No.:
7/829137
Inventors:
J. David Carlson - Cary NC
Keith D. Weiss - Cary NC
Assignee:
Lord Corporation - Erie PA
International Classification:
C10M16904
C10M17100
US Classification:
252 74
Abstract:
An electrorheological material comprising a carrier fluid and an atomically polarizable particle component. The atomically polarizable particle component has a crystalline lattice structure which allows atoms to shift position with respect to each other in response to the application of an electric field. The electrorheological materials are subjected to an alternating current electric field at a frequency of at least 500 Hz. The materials exhibit substantial electrorheological activity over a broad temperature range.

Ionic Dye-Based Electrorheological Materials

US Patent:
5306438, Apr 26, 1994
Filed:
Dec 13, 1991
Appl. No.:
7/806981
Inventors:
J. David Carlson - Cary NC
Keith D. Weiss - Cary NC
Joseph E. Bares - Bartlesville OK
Assignee:
Lord Corporation - Erie PA
International Classification:
C10M16904
C10M17100
US Classification:
252 74
Abstract:
An electrorheological material containing a carrier fluid and an ionic dye particle component which is an ionically charged compound based on or derived from a conjugated hydrocarbon compound. A preferred ionically charged compound contains at least one aromatic nucleus that has been sulfonated and/or carboxylated to form a negatively charged system which has, in turn, been offset with a positive ion. The electrorheological material is useful for creating aesthetic visual effects and responds quickly to an electric field.

Temperature Independent Magnetorheological Materials

US Patent:
5599474, Feb 4, 1997
Filed:
Apr 18, 1994
Appl. No.:
8/229270
Inventors:
Keith D. Weiss - Cary NC
J. David Carlson - Cary NC
Theodore G. Duclos - Holly Springs NC
Kirk J. Abbey - Raleigh NC
Assignee:
Lord Corporation - Cary NC
International Classification:
H01F 144
US Classification:
252 6252
Abstract:
A magnetorheological material containing a particle component and a carrier fluid or mixture of carrier fluids having a change in viscosity per degree temperature (. DELTA. eta. /. DELTA. T ratio) less than or equal to about 16. 0 centipoise/. degree. C. over the temperature range of about 25. degree. C. to -40. degree. C. The magnetorheological material exhibits a substantial magnetorheological effect and excellent lubricating properties with a minimal variation in mechanical properties with respect to changes in temperature. The magnetorheological material is advantageous in that it provides for the design of devices that are smaller, more efficient and consume less power.

Magnetorheological Fluid Composite Structures

US Patent:
5547049, Aug 20, 1996
Filed:
May 31, 1994
Appl. No.:
8/251562
Inventors:
Keith D. Weiss - Cary NC
Theodore G. Duclos - Holly Springs NC
Michael J. Chrzan - Raleigh NC
Lynn C. Yanyo - Cary NC
Assignee:
Lord Corporation - Cary NC
International Classification:
F16F 1503
US Classification:
188267
Abstract:
Controllable composite structure or structural elements enclose magnetotheological fluids as a structural component between opposing containment layers to form at least a portion of any variety of extended mechanical systems, such as plates, panels, beams and bars or structures including these elements. The control of the stiffness and damping properties of the structure or structural elements is accomplished by changing the shear and compression/tension moduli of the magnetorheological fluid by varying the applied magnetic field. The composite structures of the present invention may be incorporated into a wide variety of mechanical systems for control of vibration and other properties.

Method For Activating Atomically Polarizable Electrorheological Materials

US Patent:
5417874, May 23, 1995
Filed:
Dec 16, 1993
Appl. No.:
8/169615
Inventors:
J. David Carlson - Cary NC
Keith D. Weiss - Eden Prairie MN
Assignee:
Lord Corporation - Erie PA
International Classification:
C10M16904
C10M17100
US Classification:
252 74
Abstract:
An electrorheological material comprising a carrier fluid and an atomically, polarizable particle component. The atomically polarizable particle component has a crystalline lattice structure which allows atoms to shift position with respect to each other in response to the application of an electric field. The electrorheological materials are subjected to an alternating current electric field at a frequency of at least 500 Hz. The materials exhibit substantial electrorheological activity over a broad temperature range.
