Abstract: Compressor components, such as blades and vanes, having an airfoil portion with an uncoated, nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in Table 1. X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each Z distance in inches. The profile sections at the Z distances are joined smoothly with one another to form a complete airfoil shape.

Abstract: The shopping cart includes an infant seat and a safety belt restraint device for restraining the infant to prevent the infant from falling from the seat. The safety belt restraint device extends around the waist and between the legs of the infant to secure the infant in the seat.

Abstract: The invention provides a tool useful as an aid in joining pipes by welding. The tool includes means for positioning and holding an insert ring in a predetermined position with respect to the end of a pipe while the insert ring is tack-welded to an end of the pipe. Means is also included permitting the ends of the pipe to be welded to be aligned.

Abstract: A top cover (22) of flexible thermoplastic material is provided at the upper end of a bottom-loaded plastic bag of a type having a closed top (10) and a "carton" look when filled. The top cover is connected by heat seals (44, 46) to upper peripheral portions of the bag. The top cover is heat sealed to itself at (56), dividing the top cover into a base (22) and a handle (24). The handle (24) includes a hand-receiving opening (76).

Abstract: A handle web (14) is heat sealed to the gusset end of a bag web (10). The bag is a bottom filled top gusset bag which assumes a carton shape when filled. The handle web (14) has a central portion which extends over the gusset (18). Substantially D-shaped hand openings (16, 18) are formed in the handle web (14). These openings (16, 18) have inwardly-directed arcuate sides (60, 62) and substantially flat outwardly-directed sides (64, 66). Rounded corners (68, 70, 72, 74) are formed where the arcuate sides (60, 62) meet the flat sides (64, 66). This construction results in a four-sided stretching of the handle web when under load, along smoothly curving arcuate paths, providing good stress distribution in the handle web material and the elimination of tear-inducing stress concentrations.
