Abstract: A method of making a face mask including the steps of providing a plurality of lengths of Grade 2, commercially pure titanium wire, having a diameter of from about 0.21 to about 0.24 inches; forming each length at room temperature to a desired bend angle by bending the member at room temperature using rotary bending apparatus to a first bend angle that is from about 1.25 to about 1.35 times greater than the desired bend angle; and welding each of the thus formed lengths to at least one other of the lengths in an ambient, oxygen containing environment.

Abstract: A batting helmet includes an adjustable circumferential head band that allows the helmet to be worn by individuals with a wide range of head sizes while maintaining a constant air gap between the wearers head and the interior padding of the helmet. This air gap increases the elapsed time between impact of a ball with the helmet and impact between the helmet and its padding and the wearers head, thereby allowing for increased dispersion of energy through the shell of the helmet.
Abstract translation: 击球头盔包括可调节的圆周头带，其允许头盔由具有宽范围头部尺寸的个人穿戴，同时保持佩戴者头部和头盔内部衬垫之间的恒定气隙。 这种空气间隙增加了球头与头盔的撞击之间的经过时间以及头盔与其衬垫和佩戴者头部之间的冲击，从而允许能量通过头盔的壳体增加分散。
