Title: Method and apparatus for decorating cylindrical metallic members
Inventor: WOODS JACK L
IPC: B65C9/36
Filed: 1990-06-20
Abstract: ABSTRACT   A method and apparatus for decorating the exterior surface of a cylindrical member such as a food or beverage can.  A cylindrical bladder made of a resilient, elastomeric material is mounted longitudinally within a rigid support member, with the opposite ends of the cylindrical bladder being extended radially outwardly and attached to the rigid support member so as to create a closed cavity between the longitudinal sidewall of the bladder and the rigid support member.  A port is provided in the rigid support member in fluid flow communication with the cavity.  Air is evacuated from the cavity through the port to create at least a partial vacuum in the cavity.  The partial vacuum formed in the cavity uniformly extends the longitudinal sidewall of the cylindrical bladder such that the diameter of the extended bladder is at least as large as the external diameter of the cylindrical member which is to be decorated.  The cylindrical member and a transfer sheet containing sublimable dyes or coloring agents are positioned within the expanded bladder so that the transfer sheet lies flatwise around the external surface of the cylindrical member and is sandwiched between the cylindrical member and the bladder.  Gas is admitted to the cavity through the port of the rigid support member so as to produce an essentially atmospheric pressure within the cavity.  The longitudinal sidewall of the bladder contracts radially inwardly until it makes uniform contact with the transfer sheet on the surface of the cylindrical member to hold the transfer sheet in a stable, firm position on the surface of the cylindrical member. The transfer sheet, while held in place on the surface of the cylindrical member, is heated to a temperature sufficient to transfer at least a portion of the dye or coloring agent from the transfer sheet to the surface of the cylindrical member.  The transfer sheet and the decorated cylindrical member are then removed from the bladder.
Patent CA-2021247-A1 (CA)
Title: Air bag in air bag equipment
Inventor: NAKAJIMA HIDEO
IPC: B60R21/239
Filed: 1990-07-16
Abstract: The air bag 3 according to this invention is furnished with exhaust outlet 6 to discharge internal gas, and the material 8 with heat-shrinking property is provided, which blocks at least a part of the exhaust outlet 6 in normal case and shrinks to such direction as to increase the passage area of said exhaust outlet when reaction gas is introduced from the inflator 2.    Therefore, the passage area of the exhaust outlet 6 is relatively narrowed down by the heat-shrinking material 8 in normal case.  For this reason, it is rapidly expanded by reaction gas from the inflator 2.          Thereafter, the material 8 is shrinked by the heat of reaction gas and the passage area of exhaust outlet 6 is increased.  Thus, more reaction gas flows out of air bag 3, and this alleviates the impact when the air bag 3 receives the person in the vehicle.          In this case, the shrinking degree of the material 8 varies according to the ambient temperature, and the internal pressure of the air bag 3 is maintained at almost constant level regardless of atmospheric temperature.  As the result, the air bag 3 can receive the person in the vehicle always in stable condition.
