Abstract: A utility glove comprising a three dimensional molded portion formed of an elastomeric material molded onto a fabric material, wherein the molded portion has a thickness of from about 0.8 to about 10.8 mm with the elastomeric material including two or more areas of differing thicknesses within the range of from about 0.4 to about 10.0 mm. The molded portion of the utility glove has a concave palm, with the middle of the palm being set in from the edges to form a concave configuration. The utility glove is manufactured by placing a glove blank comprising a fabric material over a first mold part in the form of at least a portion of a hand and bringing at least one second mold part into molding engagement with the first mold part to create a cavity with the glove blank on the first mold part. The elastomeric material is then injected into the cavity to form a molded portion, wherein the elastomeric material is injected on the side of the fabric material opposite the first mold part.

Abstract: A one-piece mold can be used to form molded items that incorporate features or encroachments with negative draft angles, and such molded items can be removed from the mold in a single piece by lifting, tilting, or pulling, or a combination thereof, without breaking the mold or the item to be molded. The mold and method of molding are suited to a bathtub or shower unit. The mold and method of molding permit the removal of molded items with negative draft angles by coordinating the angle of the sump front wall and sump back wall with the angles of other encroachments in the molded item within specified ranges that permit one-piece removal of the item to be molded from the mold.

Abstract: A tire vulcanizing method reduces consumption energy and increases productivity of vulcanization. This method involves supplying an inert gas to an internal space of the tire via a supply pipe, discharging the gas from the internal space via a return pipe, and supplying the gas from the return pipe to the supply pipe by a rotation type circulation device. A heating device heats the circulated gas. An internal outlet gas temperature sensor detects a temperature of the gas in the return pipe. A controller decreases a rotating speed of the circulation device when the return pipe gas temperature is a rotating speed decrease temperature or more.
