  • Publication number: 20070075536
    Abstract: An airbag inflator (200, 300) for inflating an airbag has a tubular inflator housing (11) having a first end (A) and a second end (B). A gas release mechanism (80) has an exhaust port end or housing (85) at the first end (A) for releasing gas directly from the tubular inflator housing (11) to ambient air, bypassing the airbag. A heater assembly (2) containing a gas generant is located and attached at the second end (B). An igniter (3) ignites the heater assembly (2). A primary gas vent port (70) vents gas from the tubular inflator housing (11) into an airbag during normal deployment of the airbag. The gas release mechanism (80) has a passageway or opening (84) for exhausting gas from the tubular inflator housing (11) to an exhaust port (85). A seal (82, 83) seals the passageway or opening (84) of the gas release mechanism (80). An igniter 3 for opens the seal (82, 83) thereby terminating or slowing deployment and normal inflation of the airbag through the primary vent port (70).

  • Publication number: 20070075534
    Abstract: An airbag module assembly (400) has a module housing (402). An airbag (401) and an airbag inflator (200, 300) are positioned inside the module housing. The airbag inflator (200, 300) has an exhaust port end (85) extending external of the module housing (402) for venting inflation gasses directly from the airbag inflator (200, 300) externally of the module housing (402).

  • Patent number: 6807756
    Abstract: The invention relates to an iron (1) comprising a container of water (2) at atmospheric pressure. The water from the container flows through a nozzle between said container (2) and a heated and regulated steam chamber (5). An iron sole plate (3) forms the ironing surface and steam outlet holes (12) are arranged in said sole plate (3). The invention is characterized in that the iron (1) comprises means for creating a resonance or relaxation vibration in the water and steam circuit. The cyclic variation in the steam pressure is automatically maintained at an average pressure above that corresponding to the column of water available in the iron.

  • Patent number: 6446371
    Abstract: A steel or stainlees steel soleplate for a pressing iron having a working surface that will be in contact with articles to be pressed when the pressing iron is in use. The soleplate has, at the working surface, crystal grains that have been deformed by compression applied perpendicular to the working surface, the number of dislocations per unit of volume being at least 40% greater than that of the metal at the interior of the soleplate.
