Abstract: A screwdriver device including a handle having an elongate channel extending partially therethrough of the handle and an axial blade member having a first distal end and a second distal end being configured and disposed for sliding through the elongate channel of the handle and a locking mechanism configured and disposed for releasably locking the axial blade member at a first operable position relative to the handle wherein the first distal end is exposed and the second distal end is disposed within the handle. The screwdriver device further includes a first tool head disposed on the first distal end of the blade member and an ejection mechanism configured and disposed within the handle to constantly urge the axial blade member out of the locking mechanism from the first operable position to a second inoperable position.

Abstract: A ratchet wrench includes a fastener drive member and a rigid, one-piece frame having a handle portion extending along a longitudinal frame axis between a head portion and a finger loop. The fastener drive member has a pair of drive openings centered on the drive axis and facing in opposite directions, with each of the drive openings defined by one or more drive surfaces. One of the drive openings is sized to receive a fastener or driver bit of a first size and the other opening is sized to receive a fastener or driver bit of a second size greater than the first size. The finger loop has a finger receiving opening sized to receive and encircle a finger of a user. The fastener drive member is mounted in the head portion to rotate about a drive axis, and a ratchet mechanism is mounted in the head portion in operable connection to the fastener drive member to selectively transfer torque from the frame to the fastener drive member in either a clockwise or counterclockwise direction about the drive axis.

Abstract: A reversible tool holder assembly is adapted for insertion into a handle in either of two orientations to present two different ends extending from the handle. The reversible tool holder assembly includes a first barrel and a second barrel that are axially aligned, and a ratcheting mechanism that is disposed axially between the first and second barrels and configured to provide a reversible ratcheting mechanical connection between the first and second barrels. The ratcheting mechanism is configured to provide a reversible ratcheting mechanical connection or a solid mechanical connection between the two barrels.

Abstract: A gas generating device has a housing in combination with a device for igniting a gas generating composition located within the housing. The gas generating composition is 5-aminotetrazole combined with at least two inorganic oxidizers selected from potassium nitrate, potassium per-chlorate, manganese dioxide, iron oxide, and copper oxide. The housing has at least one aperture therethrough to allow the exit from the housing of gas generated therein following ignition of the gas generating composition, but restricting the flow of gas from the housing such that the gas exiting the housing has a carbon monoxide content of not greater than 200 parts per million. Such a gas generating device may be used for inflating an airbag in a vehicle safety system.
