Patent number: 6723761Abstract: A method for forming microcellular foams that causes the material to expand uniaxially during the foaming process, and a method for forming objects from the foam. Liquid crystal polymers or polymers having a planar crystalline structure are saturated with a fluid, normally a gas such as carbon dioxide. The ambient conditions are changed such that the fluid is in a supersaturated state, and the material is brought to near its glass transition temperature to induce the formation of nonspherical elongated gas-filled cells. A process for making objects, such as transducer diaphragms, from microcellular foams includes the step of forming the objects prior to the foaming process.Type: GrantFiled: February 15, 1996Date of Patent: April 20, 2004Assignee: Bose CorporationInventors: David E.

Patent number: 5992234Abstract: Methods for the prediction of the frequency of high order resonant ultrasound spectroscopy (RUS) diagnostic modes are used to limit the band width of diagnostic testing at high order mode frequencies. Testing of parts at low order frequency modes is used to calculate part dimensions, and then these calculated part dimensions are used to predict high order diagnostic mode frequencies. Lower order mode frequencies are used to predict high order diagnostic mode frequencies.Type: GrantFiled: November 3, 1998Date of Patent: November 30, 1999Assignee: Quasar InternationalInventors: George Rhodes, James J. Schwarz, David E. Thomas, Ming Lei

Patent number: 5965817Abstract: A method for temperature compensation of resonant frequency measurements of parts uses Temperature Functions which are mathematical relationships between measured resonant frequencies and temperature. The Temperature Function is used to adjust frequencies measured at any temperature to a resonant frequency at a pre-determined reference temperature. The temperature of a surrogate part or specimen can be measured to eliminate the need to touch a part being tested where the surrogate part has essentially the same dimensions and material properties and is positioned and mounted such that its temperature is essentially the same as the part being tested. The temperature function may be in the form off.sub.r =f.sub.m *(1+(T.sub.m -T.sub.r)/C)where f.sub.r is the resonant frequency compensated to the reference temperature, f.sub.m is the measured resonant frequency, T.sub.m is the measured temperature and T.sub.r is the reference temperature.Type: GrantFiled: July 28, 1998Date of Patent: October 12, 1999Assignee: Quasar International, Inc.Inventors: James J. Schwarz, David E. Thomas, Ronald Karaskiewicz

Patent number: 5704254Abstract: A steering column support having a bracket on the steering column secured to vehicle support structure by fasteners at the rear edge of the bracket. Isolator pads at the front edge of the bracket are clamped under pressure between the bracket and the support structure The isolator pads dampen vibration of the steering column and also prevent undesirable tilting or rocking of the steering column when the vehicle is in motion.Type: GrantFiled: February 13, 1995Date of Patent: January 6, 1998Assignee: Chrysler CorporationInventors: David E.

Patent number: 5641905Abstract: A method is provided for detecting resonant ultra sound (RUS) Spectroscopy peaks which is based upon taking the second derivative of the RUS spectrum. The second derivative provides a more sensitive analysis tool, and makes it possible to separate and distinguish peaks in the spectrum which are not readily discernable by other analyses of the spectrum. Analysis criteria such as cut off heights and Z-widths provide judgment criteria for identification of resonant peaks.Type: GrantFiled: December 14, 1995Date of Patent: June 24, 1997Assignee: Quatro CorporationInventors: James J. Schwarz, David E. Thomas

Patent number: 5597279Abstract: A washer for a male or female threaded fastener includes an annular ring portion and a seat portion with a cantilever portion extending therebetween. The washer hardness is selected to exceed the threaded fastener hardness by an amount that enhances the elastic deflection of the washer and reduces the tendency of the fastener to loosen. The selected hardness relationship also reduces the washer diameter dilation during loading and the permanent deformation of the washer diameter.Type: GrantFiled: March 6, 1995Date of Patent: January 28, 1997Assignee: R B & W CorporationInventors: David E. Thomas, Fred A. Boczar, Ronald D. Goforthe

Patent number: 5545262Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable surface characteristic for subsequent coating application. This can be initiated by selection of a metal of desirable metallurgy and heat history, including prior heat treatment to provide surface grain boundaries which may be most readily etched. In subsequent etching operation, the surface is made to exhibit well defined, three dimensional grains with deep grain boundaries. Subsequently applied coatings, by penetrating into the etched intergranular valleys, are desirably locked onto the metal substrate surface and provide enhanced lifetime even in rugged commercial environments.Type: GrantFiled: November 16, 1994Date of Patent: August 13, 1996Assignee: ELTECH Systems CorporationInventors: Kenneth L. Hardee, Lynne M. Ernes, Richard C. Carlson, David E. Thomas

Patent number: 5452624Abstract: Apparatus for releasably locking the tilt steering column assembly of an automotive vehicle in adjusted position. A rack on the steering column assembly is engaged by a pawl to lock the steering column assembly in the position selected by the driver. A bracket is provided to positively hold the pawl engaged with the rack and prevent it from becoming disengaged. The tilt of the steering column can only be re-adjusted by moving the bracket so that the pawl can disengage the rack.Type: GrantFiled: March 3, 1994Date of Patent: September 26, 1995Assignee: Chrysler CorporationInventors: David E.

Patent number: 5394602Abstract: The instrument panel assembly is made by initially forming an instrument panel substrate having a door-receiving notch, initially forming a door substrate, and attaching the door substrate to the instrument panel substrate so that the door substrate covers the notch and its sides extend beyond the notch and overlie portions of the instrument panel substrate. A single decorative cover layer is also initially formed. The attached substrates are positioned in a mold in spaced relation to the cover layer, and a foamable material is forced into the space to provide a foam padding for both the instrument panel and the door. The sides of the door substrate overlying the instrument panel substrate are braced to prevent distortion thereof during molding.Type: GrantFiled: June 13, 1994Date of Patent: March 7, 1995Assignee: Chrysler CorporationInventors: Adelbert T.
