5. The process according to claim 1, which comprises providing the solid particles with a diameter of less than one tenth of a minimum diameter of the cavity.
6. The process according to claim 1, which comprises passing the treating fluid through the cavity at a predetermined velocity.
7. The process according to claim 1, which comprises performing the process on one of turbine blades and heat shield elements.
8. The process according to claim 1, which comprises performing the process on the hollow component having the internal coating selected from the group consisting of aluminum oxide, an aluminide, and a compound formed of aluminum oxide and aluminide.
9. The process according to claim 1, which comprises performing the process on the hollow component having the internal coating selected from the group consisting of chromium oxide, chromide, and a compound formed of chromium oxide and chromide.
10. The process according to claim 1, which comprises performing the process on the hollow component having the internal coating selected from the group consisting of gallium oxide, gallide, and a compound formed of gallium oxide and gallide.
11. The process according to claim 1, which comprises after the abrading of the internal coating, recoating the cavity with a new internal coating.
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. A method for producing a continuous web of printed material for use in creating mailpieces, the continuous web having a width and a length, the length comprised of a series of attached sheets, the series of attached sheets comprising envelope sheets and content pages, the method comprising:
printing content pages onto the continuous web such that the content pages are rectangular in shape, having a long dimension and a short dimension, the short dimension being parallel to left and right edges of the web; and
printing envelope sheets, the envelope sheets having an envelope sheet width dimension parallel to the width of the web, the envelope sheet width dimension being the same as the content page long dimension.
2. The method of claim 1 wherein the step of printing content pages includes printing written matter such that lines of writing are parallel to the left and right edges of the web.
3. The method of claim 2 wherein the step of printing envelope sheets includes printing envelope matter such that lines of writing are perpendicular to the left and right edges of the web.
4. The method of claim 3 wherein the step of printing the content pages includes dimensioning the content page short dimension to be less than or equal to an envelope width formed from the envelope sheets, the envelope width parallel with the web width and less than the web width.
5. The method of claim 4 wherein the step of printing the content pages include dimensioning the content page to be a standard letter size.
6. The method of claim 5 wherein the step of printing the envelope sheet includes dimensioning the envelope sheet to form a standard envelope size, with the width dimension of the envelope sized to receive the short dimension of the content sheets, and a height dimension of the envelope sized to receive one third of the long dimension of the content sheets.
7. The method of claim 6 further including a step of printing BRE sheets in series with the content pages and envelope sheets, the BRE sheets being dimensioned to form BREs small enough to fit inside envelopes formed from the envelope sheets.
8. The method of claim 5 wherein the step of printing the envelope sheet includes dimensioning the envelope sheet to form a standard envelope size, with the width dimension of the envelope sized to receive the short dimension of the content sheets, and a height dimension of the envelope sized to receive one half of the long dimension of the content sheets.
9. The method of claim 1 wherein the step of printing content pages includes printing written matter such that lines of writing are parallel to the left and right edges of the web, and further including the step of:
dimensioning the content page width to be less than or equal to an envelope sheet width formed from the envelope sheets, the envelope sheet width parallel with the web width and less than the web width, and
wherein the step of printing the envelope sheet includes dimensioning the envelope sheet to form a flats envelope, dimensioned for enclosing unfolded content pages.
10. The method of claim 1 further including a step of printing a control code on one or more of the sheets for a given mailpiece, the control code including information for controlling assembly of the mailpiece.
11. The method of claim 10 wherein the step of printing the control code includes embedding mailpiece information in the control code.
12. The method of claim 10 wherein the step of printing the control code includes embedding a pointer to a mailpiece control file in the control code.
13. The method of claim 10 wherein the step of printing a control code includes printing the control codes on a portion of the sheets that is intended to be discarded.
14. The method of claim 1 wherein the step of printing envelope sheets includes printing BREs with individualized return addresses.
15. The method of claim 1 wherein the step of printing content pages includes printing content pages onto the continuous web such that two end-to-end content pages are printed across the width of the web, and the step of printing envelope sheets includes printing two side-by-side envelope sheets across the width of the web and in series with the end-to-end content pages.
