摘要:
An improved self-wound roll of a pressure sensitive adhesive coated laminate comprising a substrate which becomes dimensionally-unstable under normal processing conditions, e.g., printing, at least one layer comprising a continuous film of a normally dimensionally stable polymer adhesively fixed to one or both sides of the substrate thereby stabilizing it during processing, a transparent flexible release layer of a resin on the outwardly facing surface of the laminate, and a layer of a modified pressure sensitive adhesive on the inwardly facing surface of the substrate. The laminate can be processed without distortion, wound into rolls, unwound and applied to a surface to be decorated without delamination or shrinkage and without distortion of printed indicia, and it ultimately can be stripped without damage to the surface.
摘要:
A modified coating composition including a water based coating and a silicone component comprising 2 to 12 weight percent of the composition. The water based coating is preferably an acrylic latex paint. Preferably a filler is also included in the composition. The coating provides a sacrificial characteristic wherein layers may be removed with a stain or mark, leaving the coated surface looking new, using no more than soap and water.
摘要:
A hemming machine adapted to externally and internally hem a sheet metal fabrication comprising an anvil which itself is apertured so as to register with an aperture in the metal fabrication which is to be internally hemmed, wherein additional hemming apparatus is provided mounted at the upper end of a drive, and support means is located below and protruding up through the opening in the anvil so as to protrude the opening in the fabrication, further comprising a hemming tool displaceable vertically and horizontally having a chamfered lower leading edge, a slidable block carrying the tool at one end, drive means for positioning the slide vertically, and further drive means for positioning the block within the slide for positioning the tool horizontally, a second anvil resiliently displaceable and engaging the underside of the tool or normally raise the latter relative to its lowermost position, and wherein the upper surface of the block is adapted to withstand an impact force and transmit same to the tool to force the tool in a downward direction until the tool and block bottom on stop means. A method of internal and external hemming is also disclosed.

A press is described for prehemming and final hemming the internal periphery of an aperture in sheet material received on an anvil (10) on which the sheet material (12) is held down so that the upturned edge (14) of the aperture which is to be hemmed is substantially in alignment with the edge of the opening in the anvil (10). A composite hemming tool (40, 42) is provided adapted to perform prehemming and final hemming and carried b a tool carrier (36, 38). Drive means (24, 26) protrudes up from the press through the opening in the anvil so that a lower inclined leading edge (44, 46) of the tool substantially registers with the upturned edge (14) to be hemmed. The drive means operates so as to force the tool first of all towards the edge so as to bend the upturned edge over until it is bent through substantially 90 degrees from its upstanding position and thereafter to move in a generally downward direction so as to compress the downturned ege. A method of hemming is also described based on this machine.
摘要:
A transfer composite for in-mold decoration of molded plastic or rubber articles comprising a casting substrate having a controlled release surface, and a thin discontinuously printed pressure sensitive adhesive tape-strippable pattern deposited on the casting substrate, whereby the transfer composite is suitable for inserting into a mold and adapted to resist print-distorting movement during flow of plastics or rubbers in the mold, yet capable of permanently bonding to the molded article without the use of adhesives. After removal from the mold the casting substrate and the controlled release surface are stripped from the decorated article.
摘要:
A method of forming sheet metal skins of the inner fixed structure of a blocker door thrust reverser assembly having convex and concave curvatures. The method includes plastically stretching a sheet of metal about a mandrel having a chordwise central first axis to form a substantially convex shape. The method further includes the addition of features after the substantially convex shape is formed to facilitate plastically stretching a portion or portions of the substantially convex shape into a substantially concave shape about an axis that is substantially parallel to the chordwise central first axis.
摘要:
The invention relates to nucleic acids encoding a feruloyl-CoA:monolignol transferase and the feruloyl-CoA:monolignol transferase enzyme that enables incorporation of monolignol ferulates, for example, including p-coumaryl ferulate, coniferyl ferulate, and sinapyl ferulate, into the lignin of plants.
摘要:
A system for shipping and displaying a vehicle is disclosed. A display box includes a vehicle receiving area that has a display area and an enclosed area so that when the vehicle is located in the display box a prospective purchaser can sit on the seat. For shipping a vehicle is affixed to a first display box and a second vehicle is affixed to a second display box. The second display box is inverted and reversed and is located above the first display box to form a rectangularly shaped shipping combination. First and second disposable pillars are located between the first and second vehicles to support the two display boxes when combined to form the shipping combination. In a preferred embodiment, the pillars locate in foot receiving areas of the vehicles in the first and second display boxes.
