Abstract: Konische Hülsen können durch Ineinanderstecken zu Säulen platzsparend magaziniert werden. Sollen von solchen Säulen bei einer automatischen Beschickung an Textilmaschinen Hülsen vereinzelt werden, ist eine Vorrichtung erforderlich, die die jeweils letzte und vorletzte Hülse am Fuß einer solchen Hülsensäule ergreift und durch eine überlagerte axiale und radiale Bewegung auseinanderzieht. Die Hülsen können mit unterschiedlichen Haftreibungskräften ineinander verkeilt sein. Damit die Hülsen nicht beschädigt werden ist es sinnvoll, beim Vereinzelungsvorgang immer nur die gerade für die Überwindung der Haftreibung erforderliche Kraft aufzuwenden. Die erfindungsgemäße Vorrichtung weist zwei jeweils die letzte (9) und die vorletzte Hülse (8) umfassende Greifringe (6, 7) auf, an denen als Gesperre ausgebildete Greifer (11) konzentrisch angeordnet sind, die die Hülsen (8, 9) zwischen sich aufnehmen. Bei einer Relativdrehung der Greifringe (6, 7) um die Hülsenlängsachse gegeneinander sind die Greifer (11) mit einer bis zu Drehung der ersten Hülse (9) zunehmenden Anpreßkraft auf die Hülsen (8, 9) preßbar.

Abstract: A slide changing apparatus (10) is disclosed for use in a projection apparatus wherein photographic slides (12) can be projected onto a screen or viewed on a video monitor. The slide changing mechanism (10) includes a lever (16) having a displaceable part (26) which engages a slide (12) and transfers the photographic slide from a projection position to a slide tray (11) wherein slides (12) are accomodated. A microprocessor controls the operation of a driving apparatus (18, 38, 40, 48) which is connected to the lever (26) and actuates the lever. If a slide (12) becomes jammed during movement between the projection position and the slide tray (11) the displaceable part (26) of the lever (16) becomes displaced from its original position. The displacement of the displaceable part (26) is detected by an optical switch (20) and the optical switch outputs a signal to the microprocessor to stop a motor of said driving apparatus (18, 38, 40, 48) before damage to the jammed slide (12) can occur.

Abstract: When it is attempted to define a profile that consists of a combination of a first profile (1) and a second profile (2) which have been defined already, it is determined if the first profile (1) and the second profile (2) have an intersection or not based upon the designation of the first profile (1) and the second profile (2). When they do not have an intersection, it is determined whether at least either one of the first profile (1) and the second profile (2) is open. When none of them is open, closed profiles consisting of the combination of the first profile (1) and the second profile (2) are successively drawn so as to be discriminated from other profiles. A desired closed profile is selected when it is just drawn and, thus, the combination profile is defined.

Abstract: A method for regulating flow directions of raw material jet flows of a headbox (1) in a paper machine is improved so as no only to equalize a flow rate distribution along the widthwise direction of the paper machine but also to align the flow directions in the same direction. The headbox is provided with a header pipe block (5) having such header pipes that a flow rate through a header pipe (2B) at the end in the widthwise direction of the paper machine is set or made variable so as to be set larger than a flow rate through a header pipe (2A) at the central portion, and/or pipings disposed on the end surfaces of a flow passageway within the headbox at the downstream of the header pipes and capable of feeding liquid into the headbox, and pipings (7) disposed at the ends of the flow passageway within the headbox at the downstream of the header pipes and capable of extracting the raw material within the headbox to the outside of the headbox. The flow rates at the end portions in the widthwise direction within the headbox are increased by means of the header pipe block (5) and/or the pipings. The flow rates at the end portions in the widthwise direction within the headbox are decreased by means of the extracting pipings (7). The jet flow directions of the raw material can be regulated by combining the flow rate increasing step and the flow rate decreasing step.
