  • Patent number: 10611670
    Abstract: A sealing arrangement for a drawing furnace including a vertical center hole with surrounding heating elements for receiving a glass preform including a tapered portion connected to an extension rod. A sealing with an opening is arranged on top of the furnace. The arrangement includes an outer annular bushing arranged on top of the furnace and an inner annular bushing with a first and an opposing second vertical end. The inner bushing is positionable to surround at least part of the tapered portion with the first end positioned to the region of the beginning of the tapered portion and the second end includes protrusions on the outer surface. As the inner bushing is inserted in the outer bushing it is arranged to be movable within the outer bushing and the protrusions form supports for holding the second end of the inner bushing above the center hole.

  • Patent number: 10488310
    Abstract: The invention relates to an apparatus (1) for tensile testing of an optical fiber (11). In order to efficiently and simply test the optical fiber, the apparatus comprises a dual pulley (6) with a first circumferential surface (7) having a first diameter (D1) and with a second circumferential surface (8) having a second diameter (D2) which is larger than the first diameter (D1). A fiber inlet (10) which is delimited by the first circumferential surface (7) and the first drive belt section (2) contacts the first circumferential surface (7). A fiber outlet (13) which is delimited by the second circumferential surface (8) and the second drive belt section (3) contacts the second circumferential surface (8), and a guide (12) passes the optical fiber (11) from the fiber inlet (10) to the fiber outlet (13).

  • Patent number: 9902562
    Abstract: A device (1) designed as a chuck-jaw discharge system for conveying elongate objects includes two chains (3, 4) equipped with chuck jaws (5). The chains (3, 4) are driven by two drives (10). Each of the drives (10) includes an endless roller chain (11), in which toothed edges (13) that are fastened to the chains (3, 4) equipped with chuck jaws (5) engage. The roller chains (11) of the drives (10) are coupled to the straight, adjacent strands of the chains (3, 4) equipped with chuck jaws (5).

  • Patent number: 9574979
    Abstract: In order to test battery plate packs (12, 13), the battery plate packs are transported between conveyor belts (5, 6) while compressed to a specified thickness, and the force required for the compression is detected by measuring cells (14) while the battery plate packs are being transported, which measuring cells are associated with a pressing plate (11) associated with one of the conveyor belts (5). If the force deviates from a specified value, the battery plate pack is evaluated as faulty and is ejected.

  • Patent number: 9573774
    Abstract: A device for moving plate-shaped objects from a removal point, in which the objects are oriented substantially perpendicularly, to a delivery point, in which the objects are oriented substantially horizontally, includes a removal gripper moveable to and fro between the removal and the delivery points by a drive and which is rotated during the movement. The removal gripper is arranged on a lever so as to rotate with respect to the lever, which is pivoted to and fro by a drive. The removal gripper is connected to a shaft mounted rotatably in the lever and on which a wheel is fastened. An elongate, flexible element is placed over the wheel and fixed immovably in the direction of the longitudinal extension thereof. During pivoting of the lever, the wheel rolls on the elongate element. The movement of the gripper is thus superimposed with a rotational movement of the removal gripper.
