Filed:

Jan 28, 2005

Appl. No.:

11/046105

Inventors:

John Mack - Goodyear AZ, US
Paul Gruber - Chandler AZ, US

International Classification:

G09F 21/04

US Classification:

11602800R

Abstract:

An ornament () for a vehicle antenna () includes a rigid, non-planar body () arranged substantially vertical relative to the antenna (). The body () has discrete first and second apertures (). The first aperture () is located at a lower extremity () of the body () and the second aperture () is located at an upper extremity () of the body. The ornament () fits loosely on the antenna () so that the ornament () can swing around the antenna () in response to wind currents.

US Classification:

Abstract:

A grinding method for grinding spherical rollers is disclosed, wherein the roller has a spherical main diameter and a spherical end form ground thereon, and both spherical forms are ground on the same fixturing set-up. The workpiece is carried on a pair of locating shoes and the pre-ground flat end is driven with a magnetic face driver. A grinding wheel spindle carries first and second wheel forms for forming the roller spherical surfaces, and the surfaces are ground sequentially by feeding the first spherical form radially into the workpiece to grind the diameter, and thereafter axially shifting the wheel spindle to present the second wheel form in position where it is radially fed into the workpiece to grind the spherical end form of the roller.

Abstract:

A method and apparatus for dressing adjacent faces on a grinding wheel. A single point dressing nib and a rotary dressing wheel are mounted to a common slide oriented with its slide axis parallel to a first face on the grinding wheel. As the slide is actuated, the nib is drawn across the first face of the grinding wheel, dressing the entire face. After the single point nib traverses the first face of the grinding wheel, the rotary dressing wheel is activated and brought into engagement with a second face on the grinding wheel, adjacent to the first face. A cam is provided on the base which carries the slide, so that a tracing stylus will follow the shape of the cam and transmit the cam profile to the dressing nib as it traverses its path. In this manner, therefore, an extremely accurate profile may be dressed on a first face of the grinding wheel, and a second, potentially wear-causing face may be dressed into the grinding wheel by a dressing wheel yet the rotary dressing wheel will not introduce vibrational inaccuracies into the first face.
