  • Publication number: 20200346892
    Abstract: An elevator system (1) includes a load sensor (4, 24, 34, 44), a flexible member (2, 18, 22) and an elevator unit (10, 20, 28) arranged to move vertically in a hoistway. The system is arranged such that the load sensor (4, 24, 34, 44) detects a load from at least a fraction of the flexible member (2, 18, 22) and the fraction of the flexible member (2, 18, 22) that applies load to the load sensor (4, 24, 34, 44) changes as the elevator unit (10, 20, 28) moves vertically in the hoistway. The system further includes a non-volatile memory, arranged to store load conversion information for converting the detected load into an elevator unit position.

  • Publication number: 20070158903
    Abstract: In a first exemplary embodiment of the present invention, an apparatus for decelerating a signature comprises a movable belt arrangement, and a motor coupled to the movable belt arrangement for controllably moving the movable belt arrangement through a cyclical velocity profile. Pursuant to a feature of the present invention, the movable belt arrangement is moved through a signature engaging section with the cyclical velocity profile causing the motor to decelerate the movable belt arrangement from a first speed to a second speed while engaging a signature in the signature engaging section. The signature enters the signature engaging section at the first speed, and leaves the signature engaging section at the second speed, lower than the first speed. The cyclical velocity profile causes the movable belt arrangement to accelerate upon the signature leaving the signature engaging section, back to the first speed, prior to a next signature entering the signature engaging section.

  • Publication number: 20070095228
    Abstract: According to an exemplary embodiment of the present invention, a method for operating a multi-unit printing arrangement, including multiple individual motors is provided. The method comprises the steps of operating the multi-unit printing arrangement, stopping the multi-unit printing operation by braking the multiple motors in stop operations, and staggering impression throw operations for individual units by a preselected time delay between commencement of each impression throw operation, a duration of the time delay between commencement of sequential impression throw off operations being selected to be of sufficient duration such that there is no overlap of large torque disturbances experienced at the multiple motors.

  • Publication number: 20060237886
    Abstract: According to the invention, the first end (2a) and the second end (2b) of the pre-tensioned spring (2) are positioned in their pre-tensioned states against a first stop (1a) and a second stop respectively (1b). The rotating body (1) is first rotated at least X times about its longitudinal axis, without the action of external forces, whereby the first end (2a) engages once in a cam wheel (3) during each rotation, said wheel having at least X+1 teeth (3b) and at least one cam (3a) that runs parallel with the teeth (3b). The cam wheel (3) thus rotates one tooth (3b) further with each rotation of the rotating body (1). After at least X continuous rotations, the rotating body (1) is subsequently subjected to pre-tensioning until the cam wheel (3) and its cam (3a) lies against a third stop (6) and the first end (2a) simultaneously engages in the cam wheel (3).
