Abstract: A fastening element for holding onto a stud, the fastening element having a body extending along an axis and including a wall of substantially uniform thickness that partially defines an axially extending through hole; a sprue located only at a single axial injection end of the wall; and wherein the fastening element is formed of an injection molded liquid crystal polymer material that flowed into the body via the sprue.

Abstract: In a clip for fastening to a strip or rib, in particular on a motor vehicle, having a single-piece body made of plastic that has a retaining region, the retaining region has a receiving slot with an insertion opening and a locking finger. The locking finger is attached to a first guide section and extends from its fastening end in the insertion direction and in the direction of a second guide section. The locking finger has an insert that forms a tongue projecting from the free end of the locking finger.

Abstract: A wrapping tape for automatically circumferentially wrapping an axially extending article, in particular a cable or a cable loom, the tape suitable for wrapping around the article and then tautened and joined to itself in an overlapping manner by a joining tool. The wrapping tape comprises a core with a contact area, which is designed to rest on the article; and tabs protruding laterally from the core. A tab forms such an angle with the contact area that the joining tool can engage behind the tab when the tape is wrapped tightly around the article, and without the tool engaging behind the contact area, while tabs of overlapping tape portions are joined to one another.

Abstract: A fastening element for fastening a longitudinally extending article, in particular a cable or a cable loom, which is to be fixed to a component, in particular to a motor vehicle body part, with a wrapping tape. The fastening element comprising a body including a first cheek element, a second cheek element, and at least two connection struts which connect the cheek elements to one another in a longitudinal direction of the body, and which define an opening for receiving the tape. The tape is insertable into the opening substantially transversely to the longitudinal direction, in order to circumferentially wrap the article with the wrapping tape.

Abstract: A method and apparatus for automatically circumferentially wrapping a cable with a wrapping tape connectable to a fastener, wherein the apparatus comprises: a gripper device with movable jaws, a joining tool, a first feeder; a second feeder, and a control device. The jaws permit the fastener and the wrapping tape to be circumferentially guided around the cable. The joining tool joins overlapping portions of the tape, and is adapted to join the tape separately to the fastener. The first feeder advances tape to the gripper device during the wrapping operation and retracts the tape during tautening. The second feeder feeds the fastener to the gripper device. The control device locks the fastener in a predefined circumferential position relative to the cable, and causes the first feeder to advance the tape forward relative to the fastener by a predefined tape length.

Abstract: In a method for primary molding of a molded part having an opening and an internal thread formed in the opening, segments of a course of the inner thread arranged in two different sectors of the opening are formed by molding cores projecting into the opening. For release from the mold, the mold cores are withdrawn from the molded part radially with respect to the longitudinal axis of the internal thread. A molded part produced according to the method has an opening and, formed in the opening, an internal thread that has segments of a course of thread located in different sectors of the opening, wherein one core opening is opposite each segment of the internal thread, which opening penetrates the wall of the molded part radially outward.

Abstract: A heat exchanger is disclosed which has a collecting pipe having formed therein at least one slot whereby the slot lies in a plane roughly perpendicular to the collecting pipe longitudinal axis. A flat pipe, which is capable of accommodating a fluid, a partition, or the like can be inserted into the slot, the narrow sides of the slot being limited by parallel-running slot walls of the collecting pipe which extend roughly along a tangent to a circle around the pipe longitudinal axis. The slot length, determined by the spacing between the slot walls, corresponds at least to the pipe inner diameter. A method of making a slot in a collecting pipe also is disclosed whereby in order to produce the smallest possible pipe diameter and high compressive strength, a stable and seal-tight connection of a laterally issuing structural part is ensured.

Abstract: The invention relates to a device for clamping and unclamping of components with the aid of a clamping flange, at least one of said components being clamped by the hook of said device, the clamping force being transferred via a bolt linked with the hook and a nut that can be operated from the external side. The invention provides for a device clamped and unclamped by means of a tool such as an impact wrench, the head of which need not be tilted, lifted or lowered.The aim of the invention is achieved by means of nut (5) that is arranged in a fixture and that can be turned but yet remains in a defined position, and by means of hook (10) that is linked with bolt (6) and guided with the aid of element (12) in groove (11) of fixture (5), the hook thus performing upward and downward motions and being swivelled by at least 45.degree. around its longitudinal axis for unclamping the flange.
