Abstract: A patient restraint member is provided for medical procedures, such as radiation therapy. The restraint member is formed from a sheet of thermoplastic material that can be softened upon heating so as to be formable into a shape corresponding to a patient's body part to be restricted and setting upon cooling to retain the shape. The sheet includes spaced apart groups of perforations which minimize shrinkage during the formation process. The sheet also includes solid bands extending between the groups of perforation to provide rigidity and strength to the formed sheet.

Abstract: An air spring and shock absorber unit for use in vehicle suspension systems or cab suspension systems comprising a shock absorber mounted within an air spring. The lower end of the air spring bellows is attached to the air spring piston in such a manner which enables the lower end of the bellows to be disconnected from the air spring piston without damaging the crimp ring which connects the bellows to the piston.
