Abstract: SAVacook is a miniature rose which can be grown quite satisfactorily in a greenhouse or as a hardy, garden perennial. It blooms continually throughout the growing season with buds and flowers of an apricot-yellow blend. Blooms are most often born in clusters but also singly, making them good for cut flowers. The plant, itself, grows 18 to 24 inches tall in a nice mounded form making it ideal as either a specimen plant or in a border. This variety does need winter protection in severe climates.

Abstract: An apparatus and method for attaching inconsistent length plastic handles to a container. The apparatus comprises a mandrel having a bottom diameter less than that of the container and a top diameter greater than that of the container. The container rests on the mandrel until uneven forces are applied by attachment of a handle having unequal length sides, at which time the shorter arm of the handle engages the container first, causing the corresponding sides of the container to slide upwardly on the mandrel and the opposite side to slide downwardly.

Abstract: A method of manufacturing a functional part of synthetic resin material in a bearing plate so as to have good bearing properties. The functional part is formed at a bearing plate by a synthetic-resin injection-molding technique (outsert molding technique) with a bridge portion extending through a hole having hole walls of the bearing plate and with integral retaining portions disposed at both plate surfaces laterally of the hole.
