Abstract: A gas generator comprising a housing (3) made of metal and having an initiator shell (1) and a closure shell (2), (a) combustion chamber(s) (5, 5a, 5b) formed in the housing (3) and packed with gas generant (4) that generates high temperature gas by burning, (a) filter member(s) (6, 6a, 6b) arranged around the combustion chamber(s) (5, 5a, 5b), (an) igniter device(s) (7, 7a, 7b) put in the housing (3) for igniting and burning the gas generant (4) in the combustion chamber(s) (5, 5a, 5b), and a plurality of gas discharge holes (8) formed at the housing (3), for discharging gas generated in the combustion chamber(s) (5, 5a, 5b), wherein either or both of the initiator shell (1) and the closure shell (2) forming the housing (3) has a head portion (14, 10) of a semispherical form or an oval semispherical form and a cylindrical portion (13, 9) of a diameter (D) formed continuously from the head portion (14, 10), and wherein a ratio H/D between the diameter D of the cylindrical portion (13, 9) and a distance H betw

Abstract: An improved multiple roller spinning machine for spinning vehicle one-piece wheels is disclosed in which the roller holder is capable of sliding in a direction parallel with the axis of spinning and has a hydraulic cylinder which moves through its axially movable piston rod the holder horizontally thereby bringing the multiple rollers sequentially in to an operating position just above the wheel material clamped between the dies of the driving and driven spindles. Each of the multiple rollers is coupled to a control hydraulic cylinder which drives through its piston the respective roller vertically between a retracted position and a drawing position where the roller is pressed against the periphery of the wheel material.

Abstract: Described herein is a method for shaping aluminum wheels, which comprises the steps of: (A) supporting opposite rim portions of a cylindrical forging aluminum work substantially of H-shape in section by means of spinning dies, and subjecting the work to primary spinning including press-shaping by a work-stretching first spinning roller and preliminary spinning by a second spinning roller; (B) flaring the inner end of the rim; (C) annealing the work to remove the work-hardening resulting from the flaring operation; and (D) subjecting the work to secondary spinning including final spinning by the second spinning roller and corner R-finishing by a third spinning roller.
