Abstract: A seat belt retractor includes a spool driven by an electric motor. Seat belt webbing is wound around the spool. A worm wheel rotates with the spool and meshes with a worm that is axially movable. A set of electrical brushes is axially movable with the worm along the shaft. The set of electrical brushes is electrically coupled to a control circuit through a set of conductor strips. The set of brushes slide along the set of conductor strips as the worm moves axially. In response to movement of the brushes along the conductor strips, the control circuit provides signals to control the motor and, thus, the spool.When an occupant initially withdraws the webbing to buckle the webbing, the tension force acting on the webbing moves the worm axially. In response, the motor is actuated to rotate the spool in the belt withdrawal direction and provide motorized assist for the webbing withdrawal.

Abstract: A seat belt retractor has a first relatively strong spring and a second relatively weak spring which bias the spool of the retractor on which the seat belt is wound in a belt retraction direction. A mechanism is actuatable to block the bias of the first spring from acting on the seat belt so that only the second spring acts to bias the seat belt in the belt retraction direction. The first spring acts between the retractor frame and a ratchet wheel and the second spring acts between the ratchet wheel and the spool of the retractor. A pawl is movable into a first position to block the ratchet wheel from rotation in the belt retraction direction so that only the second spring acts to bias the seat belt in a belt retraction direction. A cam is rotatable relative to the retractor spool and controls movement of the pawl.

Abstract: A method of making and of reading markers at control positions on a length of magnetic tape having light-impeding coatings on opposed sides of a transparent tape substrate. Markers are recorded by directing focused beams to control positions along longitudinal areas of the magnetic tape. The beams have an energy sufficient to ablate the coatings, but to leave the tape substrate intact. Raster scanning of the control position provides rectangular markers at prescribed positions. The longitudinal extent of these rectangular markers generally conforms to the ANSI Standard for end of tape and beginning of tape marker patterns, while the transverse extent of the markers is greter than the longitudinal extent.

Abstract: A power returnable tape rule has an improved connection between the inner end of the power spring and the hub. The hub has an axially elongated passage therethrough with shoulders at the axial ends thereof which seat in notches formed in the edges of the spring extending therethrough. These shoulders are located intermediate the transverse dimension of the passage and are inclined upwardly towards the axial ends. Bosses on the opposing wall of the passage limit the clearance in the passage and thereby the opportunity for the spring to be lifted from the shoulders.

Abstract: Methods and apparatus for reading a luminescent and substantially transparent bar code 1 on a background surface 2 whose reflectance may vary over the coded area. Light 7 scans (70), and excites luminescence 8 in, the bar code 1. The light 7 also reflects (9) without luminescence from the background surface 2 of the bar code 1. A first electrical or optical signal 11 is provided (4) responsive to the reflected nonluminescent light 9, and a second electrical or optical signal 10 is provided (4) responsive to the luminescent 8. Typically the first signal 11 is processed (5) to provide a third signal 31 that varies with background reflectance substantially as does the second signal 10; and the second and third signals 10, 31 are combined (5) to provide a fourth signal 12 that is substantially independent of background reflectance in the coded area, and which is decoded (6) to provide the desired reading.
