Patent CA-2156367-A1 (CA)
Title: Pre-forge aluminum oxide blasting of forging billets as a scale resistance treatment
Inventor: DILLON GARRY L
IPC: B24C1/00
Filed: 1995-08-17
Abstract: A ferrous forging billet is treated before heating for forging by grit blasting it with aluminum oxide grit having a pre-blasting particle size in the range of from about 100 microns to about 180 microns, at a pneumatic pressure in the range of from about 60 psi to about 160 psi, and for a time period in the range of from about 30 seconds to about 60 seconds, so as to remove pre-existing scale from the surface of the billet stock, to roughen the cleaned billet surface and to embed particles of aluminum oxide in the cleaned and roughened billet surface, thereby to form a tightly adhering deposit of aluminum oxide particles which are dispersed over the billet surface and cover at least 10% thereof. This substantially  inhibits  the  formation  of  oxides  on  the surface of the billet during heating for forging.

Patent CA-2160402-A1 (CA)
Title: Process of Forming Dough on a Paperboard Preform
Inventor: DONNELLY DAVIS A
IPC: A21C11/00
Filed: 1995-10-12
Abstract: To facilitate baking a frozen dough product in an oven having a rack formed of aligned bars, the dough product is formed over an oven-safe paper sheet which has a plurality of die-cut holes. This sheet serves as a baking substrate and obviates the need for a baking pan. The paper sheet is formed with the dough product, and the dough extends through the holes and locks the sheet to the dough. The end user may thus remove the frozen dough product together with the sheet from a backing perform and place the assembly on an oven rack for baking. As the dough thaws the crust will loose its stiffness. The sheet however, will prevent the more pliable crust from distending through the oven rack before the dough has become baked and rigid. The sheet forms a backing which restrains flow of the dough, while at the same time the holes permit the escape of gases from the bottom of the crust and ensure uniform baking. Furthermore, the holes allow direct radiant heating of the dough product through the paper sheet. The position and size of the holes may be adjusted to achieve desired uniformity of baking of the dough product. The finished baked dough product, such as dinner rolls or a pizza crust, may be removed from the oven with the sheet attached thereto, and the baked dough product may be served directly from the sheet.

Title: Retroreflective article and method of making same
Inventor: BILLINGSLEY BRITTON G
IPC: G09F13/16
Filed: 1995-03-28
Abstract: A retroreflective article has first (32) and second (34) segments each comprising a binder layer and a multitude of microspheres (36) partially embedded in the front surface of the binder layer (42). The first segment also has an opaque reflective metal layer (38) disposed on the embedded portions of the microspheres; whereas, the second segment lacks such an opaque reflective metal layer and thereby allows the color of the underlying binder layer to be seen from the front side of the retroreflective article. The first and second segments display noticeably different colors under daytime lighting conditions, and each possesses a distinctly different retroreflective efficiency when viewed under retroreflective lighting conditions. The first and second segments therefore stand out in contrast to each other to enhance the conspicuity of the retroreflective article.
