Abstract: A temporary covering for a window or the like, including an elongate paper-like sheet having equidistant parallel pleats defined by creases extending across the sheet. An adhesive fastening strip is located at the top end of the sheet for fastening the sheet to a window, window frame, or the like. When mounted to window or window frame, the temporary window covering extends downwardly to a selected variable length, while maintaining a pleated appearance.

Abstract: The present invention is directed to a process for producing a molded product by a) reacting i) an organic polyisocyanate, ii) an hydroxyl group containing component having an average hydroxyl number of 300 or more, an average hydroxyl functionality of from 2 to 8, and an average molecular weight of no more than about 500, and iii) a carboxylic acid, in a closed mold, b) allowing the components to react, and c) removing the product from the mold.

Abstract: A process for producing a molded product by reacting an organic isocyanate component with an isocyanate reactive component. If the isocyanate component is based on a prepolymer of an isocyanate and a fatty acid ester, then the isocyanate reactive component must contain a fatty acid. Alternatively, if the isocyanate component contains a fatty acid, then the isocyanate reactive component must contain a zinc carboxylate. The system will release from bare steel.

Abstract: The mold broadly consists of an upper and lower mold part. The parts define a mold cavity when the mold is in the closed position. A channel is provided in one of the parts, with the channel completely surrounding the cavity. One upper edge of the channel forms at least a portion of the outer edge of the mold cavity. The channel is at least partially filled with an elastomeric material. A shear plate is attached to the other part in a location opposite the channel. When the mold is in the closed position, the shear plate enters the channel, presses against the elastomeric material and presses against the outer edge of the mold cavity. The shear plate is also provided with one or more tapered slots which allow gases to escape from the mold cavity when the mold is in the closed position.

Abstract: The present invention is directed to a process for producing a molded product comprising(A) reacting:(i) an organic polyisocyanate having an isocyanate group content of from 5 to 45% by weight, preferably from 15 to 35% by weight, and most preferably from 20 to 35% by weight, prepared by reacting:(a) an organic di- and/or polyisocyanate, and(b) an active hydrogen containing fatty acid ester prepared by reacting an alcohol or polyol with an aliphatic, saturated or unsaturated fatty acid, said ester being characterized in that at least one aliphatic acid which contains more than 8 carbon atoms is built into the molecule, said ester further characterized as having an acid number of from 0 to 100 and a hydroxyl number of from 0 to 150 with at least one of said numbers being greater than zero, said ester having an average molecular weight of from 500 to 5000,(ii) an isocyanate reactive component comprising:(a) from about 0.
