Abstract: A necklace that contains a gear assembly within a housing where gears of the gear assembly are rotated by a driving component. The driving component is a necklace chain where the chain, for example is a ball chain or a box chain that passes through openings in a housing wall and is configured to physically rotate gears.

Abstract: The present teachings provide for a door linkage system including a drive side and a driven side. The drive side includes a drive gear and a drive arm. The driven side includes a driven gear configured to mesh with the drive gear and a guide plate in cooperation with the drive arm. The drive side moves the driven side between an open position and a closed position. Proximate to the open and the closed positions, the drive arm moves the driven side. Between the open and the closed positions, the drive gear moves the driven side.

Abstract: The invention relates to an apparatus for the transmission of movements and forces from deflection lever connected with a drive means onto at least one linearly movable element, particularly of a dobby weaving machine, whereby the deflection lever is supported rotatably about an axis, whereby the deflection lever comprises a first and a second lever arm arranged at an angle relative to one another, and whereby the force introduction of the drive means occurs on one of the lever arms. The pivoting movement of a deflection lever shall be converted into a linear movement with low frictional losses and wear.
