Abstract: A vehicle seat belt retractor with a tension-reducing mechanism comprises a main winding spring biasing a toothed wheel in the belt-winding direction and an auxiliary winding spring biasing the reel shaft relative to the wheel. The positions of a stopper pawl biased by an over-center spring are controlled by a clutch plate associated with the wheel such that the wheel is stopped by engagement by the pawl after the belt is pulled out and done up, the slack is allowed to be taken up, and the user pulls the belt out slightly, thereby establishing the reduced-tension state. The pawl is released from the wheel to restore the winding bias of the main spring by a releasing clutch ring if more than slightly less than one revolution of the reel is required to take up slack in the belt after the reduced-tension state is attained.

Abstract: A wire strand for reinforcing elastomers such as tires and conveyor belts comprises multiple individual filaments bundled in a core and an outer layer on a common axis. Each individual filament is tangential to all adjacent surrounding filaments and all filaments have identical lay direction and length in a hexagonally close-packed cross section, which is to say that the strand filaments are of bunched configuration. In accordance with the invention, the outer layer includes filaments of differing diameters so disposed with respect to each other and with respect to the filaments of the core that the outer edges of all filaments in the outer layer, viewed cross sectionally, lie substantially on a common radius from the strand axis.

Abstract: A film cassette is disclosed wherein a pair of annular constraining flanges are coaxially spaced on a film spool. The flanges radially confine the outermost convolution of a film roll wound on the spool to prevent the film roll from clock-springing against the cassette shell and thereby hindering film movement. A pair of internal cam members are rotatable from outside of the cassette shell to open a light lock by slightly separating opposite throat portions of the shell. Another pair of internal cam members are rotated with the first pair to flex a limited section of the flanges apart an axial distance sufficient to radially free a corresponding section of the outermost convolution. Then, rotation of the film spool will cause successive sections of the flanges to be momentarily flexed apart, and each freed section of the outermost convolution will be advanced automatically to the outside of the cassette shell.

Abstract: To improve the efficiency of a rotating air layer produced by an air injection nozzle and rotating in a substantially cylindrical space, the rotating air layer being intended to rotate a twisted fiber structure introduced through an inlet duct, there is provided a tube extension at the inlet duct. This tube extension forms a guide for the air flow injected tangentially and at an inclination by the air injection nozzle with respect to the direction of travel of the twisted fiber structure. As a result of this guide, the rotating air layer can form before it engages or contacts the twisted fiber structure. As a result there is increased the rotation of the engaged twisted fiber structure per unit length thereof, resulting in increased strength of the twisted fiber structure and the yarn ultimately produced therefrom with low air consumption.
