1. A clip on car visor extension for use on a front automobile sun visor wherein the front automobile sun visor only partially blocks out sun rays shining through a front windshield and adjacent side windows of the motor vehicle with unblocked sun rays shining into the frontal and peripheral view of an occupant in the motor vehicle’s front seat, said clip on car visor extension comprising:
(a) a clip member for adjustably mounting on the front automobile sun visor of the motor vehicle, said clip member having two elongated legs and a connecting leg wherein the elongated legs are joined at closed ends as best seen in FIG. 3, to the connecting leg and further wherein at least one of the two elongated legs have a distal end with a grabber means for gripping the front automobile sun visor; and
(b) a glare reducing composite sheet element adjustably positioned on the connecting leg of the clip member, said glare reducing composite sheet element having a central hole adjacent to lateral edge area; and
(c) a rivet like fastener that adjoins the surfaces of clip member and glare reducing composite sheet to each other and when properly attached, permits for radial rotation and holding in place by torque friction said glare reducing composite sheet element on the clip member to a desired angle whereby unwanted sun rays are blocked out by the glare reducing composite sheet element by horizontally or laterally positioning the clip member on the front automobile sun visor and by rotationally positioning the glare reducing composite sheet element on the clip member.
2. The clip on car visor extension of claim 1 wherein the two elongated legs of the clip member each have an open end with an inside face and further wherein the grabber means a set of ridges extending substantially horizontally across each inside face at the open ends of the elongated legs.
3. The clip on car visor extension of claim 1 wherein the two elongated legs of the clip member are spaced from about 0.25 inches to about 0.75 inches apart at the closed ends for vertically adjustable positioning on the motor vehicle’s automobile sun visor.
4. The clip on car visor extension of claim 1 wherein each of the two elongated legs of the clip member ranges from about two inches to about four inches in length.
5. The clip on car visor extension of claim 1 wherein the glare reducing composite sheet element is generally rectangular shaped with a width of about three inches to about eight inches and a height of about three inches to about five inches.
6. The clip on car visor extension of claim 1 further wherein the glare reducing composite sheet element is tinted with a colorant.
7. The clip on car visor extension of claim 1 further wherein the glare reducing composite sheet element has a width of from about three inches to about eight inches and a height of from about three inches to about five inches.
8. The clip on car visor extension of claim 1 further wherein the glare reducing composite sheet element is opaque.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1-16. (canceled)
17: Method for determining a sintering shrinkage of a pre-sintered body, the method comprising:
providing a green preform with at least one design feature;
pre-sintering the green preform to form a white body;
recording at least one change in the at least one design feature with the pre-sintering; and, determining an expected sintering shrinkage to a dense-sintered component using the recorded at least one change.
18: The method as recited in claim 17, further comprising:
determining the expected sintering shrinkage to the dense-sintered component for a first number of white bodies, wherein the first number of white bodies exceeds a second number of green preforms; and
recording the at least one change in the at least one design feature of the second number of green preforms during the pre-sintering.
19: The method as recited in claim 18, further comprising measuring a length for each white body of the first number of white bodies.
20: The method as recited in claim 18, further comprising recording a density for the second number of green preforms.
21: The method as recited in claim 18, further comprising:
recording at least one change in the at least one design feature with the sintering to the dense-sintered component for the second number of green preforms.
22: The method as recited in claim 21, further comprising recording a density of the dense-sintered component for the second number of green preforms.
23: The method as recited in claim 17, further comprising:
recording a distance between two design features to obtain a first recorded result; and
determining the expected sintering shrinkage using the first recorded result.
24: The method as recited in claim 17, wherein compression moulding is used to provide the at least one design feature to the green preform.
25: The method as recited in claim 17, wherein machining is used to provide the at least one design feature to the green preform.
26: The method as recited in claim 17, wherein the recording is performed using a processing machine after the pre-sintering.
27: The method as recited in claim 17, wherein:
the at least one design feature includes at least two design features; and
the determining includes calculating the shrinkage of the white body in various directions.
28: The method as recited in claim 17, wherein:
the at least one design feature includes a plurality of design features;
the recording includes recording the at least one change in the plurality of design features; and
the determining includes determining an average of the expected shrinkage.
29: The method as recited in claim 17, wherein at least one design feature includes an aparture.
30: The method as recited in claim 17, wherein the at least one design feature includes an indentation.
31: The method as recited in claim 17, wherein the white body includes a ceramic material.
32: The method as recited in claim 31, wherein the ceramic material includes at least one of zirconium oxide and aluminium oxide.
33: The method as recited in claim 17, further comprising:
processing the white body so as to provide a medical or dental component.
34: The method as recited in claim 33, wherein the processing includes the sintering.
35: A medical or dental component produced by a method comprising:
providing a green preform with at least one design feature;
pre-sintering the green preform to form a white body;
recording at least one change in the at least one design feature from the pre-sintering;
determining an expected sintering shrinkage to a dense-sintered component using the recorded at least one change; and
processing the white body so as to provide the medical or dental component.
36: The component as recited in claim 35, wherein the processing includes the sintering.
