Abstract: A method for forming a parachute of a round configuration when deployed, and having a diameter D and a central vent of a diameter d, includes the steps of sewing together a plurality of elongated bolt widths of parachute cloth, the parachute cloth bolt widths being sewn together along lengthwise edges thereof to provide a sheet having seams interconnecting pairs of the bolt widths of cloth, the sheet having a width of about ½ D, less ½ d, cutting triangular pieces from the sheet, cutting opposite side edges of the triangular pieces to a length such that each side edge length is substantially equal to ½ D, cutting the triangular pieces from outboard edge ends to provide arc-shaped outboard edges, and sewing together the triangular pieces along the side edges thereof to produce main seams and to provide a round parachute canopy.

Abstract: The present invention provides a process for selectively alkylating pyrazoles comprising reacting a 3(5)-cyano-1H-pyrazole-4-carboxylic acid ester with a C.sub.4 -C.sub.8 alkene, or a C.sub.5 -C.sub.6 cycloalkene substituted at the 1-position with a C.sub.1 -C.sub.4 alkyl group, and a strong acid in a solvent which contains a strong electron withdrawing group. Also provided are new 3(5)-cyano-1H-pyrazole-4-carboxylic acid ester useful as starting materials in the process of the invention.

Abstract: Pollen formation in cereal grain plants is inhibited by application of a 4,5-dicarboxy or 5-carboxamido-4-carboxy (or derivatized carboxy)-1-(3,5-disubstitutedphenyl)pyrazole. Use of the compounds facilitates the production of hybrid seed.

Abstract: A collapsible shipping container having a base structure provided with upstanding wall catches capable of being received in structurally interfitting relation within respective pockets defined within side walls thereof. A cover structure is provided with depending wall catches which are received within respective upwardly directed pockets of the side walls, thus securing the base structure to the side walls and the cover to the side walls. The cover structure is also provided with shipping catches which are received within shipping catch slots or openings defined within the base structure in the collapsed condition of the shipping container. In this condition the walls are stacked on the base structure and are restrained by the shipping catches and wall catches to secure the walls within the collapsed shipping container for shipping and handling in the collapsed condition thereof.

Abstract: Pollen formation in cereal grain plants is inhibited by application of a 4-carboxy(or derivative)-1-aryl-5-pyrazolecarboxamide. Production of hybrid seed is facilitated by use of the compounds.
