  • Publication number: 20240200590
    Abstract: The invention relates to a retaining nut (1) for a threaded cable connection which is provided for special installation situations. Here, a subsequent assembly of the retaining nut on a cable (60) with an integrated cable sleeve (70) is not possible. According to the invention, the retaining nut (1) has a two-part construction comprising a main part (10) and a ring (15). By virtue of the two-part retaining nut (1), it is possible to arrange the ring (15) on the cable (60) behind the cable sleeve (70) at an earlier point in time in the assembly process. In this manner, the assembly of the cable (60) with the cable sleeve (70) and the ring (15) is ensured and a subsequent connection of the main part (10) and the ring (15) is made possible.

  • Publication number: 20190322013
    Abstract: A tool is disclosed for the production of foamed insulation boards with two side faces lying opposite one another and all-round end faces such as facade insulation boards for insulating buildings. The tool has two mold halves, each having a mold frame and a mold base. The two mold halves together bound a mold cavity, which corresponds roughly to an insulation board to be produced, with the mold frames defining or bounding the end faces of the insulation board to be produced and the mold base defining or bounding the side faces. A setting device sets the position of the two mold halves in a plane parallel to the mold bases. The setting device is designed for stepless setting of the position of the two mold halves relative to one another.

  • Patent number: 8776307
    Abstract: The invention relates to an air volume flow and pushing force control device for a vacuum cleaner that has at least a motor, a dust receptacle and a suction nozzle, comprising a controller for controlling the motor power, a first sensor for detecting the air volume flow, which in conjunction with the controller forms a first control loop in order to maintain the air volume flow at a prescribed air volume flow value on the basis of the signal of the first sensor. The control device further comprises a second sensor for detecting a pushing force that is required for pushing the suction nozzle, and in conjunction with the controller, forms a second control loop in order to maintain the pushing force below a prescribed value on the basis of the signal of the second sensor, and a control loop selection device that activates one of the two control loops as a function of the signals of the two sensors.

  • Patent number: 8210598
    Abstract: The present invention relates to a wind blocker arrangement (1) for a personal vehicle embodied as a cabriolet, having a roller device (5) comprising a shaft (12) and a material web (7) that may be rolled onto the shaft (12), having a bow (8) to which the material web (7) is attached and by means of which the material web (7) may be unwound from the shaft (12), and having two lateral arms (9) that, when the material web (7) is extended, are disposed in the region of the lateral edges (14) of the material web (7) and that are pivotable transversely to the rotational axis (13) of the shaft (12). A particularly compact and comfortable construction may be achieved if the arms (9) are drive-coupled to the bow (8) such that the arms (9) pivoting open causes the bow (8) to pull out the material web (7).

  • Patent number: 8072608
    Abstract: The apparatus and method according to the invention includes an objective (8) which is capable of operating basically in two different measuring modes. In a first interference mode, a measuring object (9) is interference—optically measured. In a second imaging operating mode on a detector array (12) designed like a camera, an optical image is generated, which is supplied to an image processing routine. The switching over between the two operating modes occurs by switching the illumination devices which are associated with different locations of the beam path of the apparatus—when viewed from the camera, one in front of a beam divider and the other behind the beam divider, which couples a reference light path to the beam path.

  • Patent number: 7808647
    Abstract: A method for detecting shapes based on interferometric observation of an object surface subjected to narrow-band lighting. Movement of the interferometer (1) relative to the object surface (2) generates a measuring signal on a photo receiver, e.g., camera circuit (5), from which two extremely closely positioned signal frequencies (fo) and (fo+?f) are extracted. The phase difference between the two signal components is used for determining the distance and/or the change in distance. The method has a large unambiguousness range, making it possible to have a large depth measurement range, and can be used for workpieces having offset areas on the surface, wherein the measurement is not disturbed along the edges and the offset areas. The method also allows examining strongly inclined surfaces having a steep inclination such that that traditional methods based on evaluating interference lines cannot be used because of a high density of the interference lines.

  • Patent number: 7545505
    Abstract: The apparatus according to the invention comprises an object lens which can operate in at least two different measuring modes. In a first, interference mode a workpiece is measured by means of interference optometry. In a second, imaging measuring mode an optical image is produced, for example, on a camera-like detector array and may be applied to an image processing routine. Switching between the two measuring modes is performed by the type of illumination of the object lens and an element which is disposed preferably in the reference beam path of an interferometer and which activates or deactivates the reference beam path dependent on the spectral composition of the utilized light. In this manner a simple and rapid changeover between the two measuring modes is provided, without the need for replacing or even for moving the object lens.

  • Patent number: 7486394
    Abstract: A measuring head (4) according to the invention comprises the combination of a zone lens (26), which is preferably a diffractive lens, with a hemispherical lens (23) or a GRIN lens (33). This represents a concept capable of miniaturization, resulting in very slender measuring heads (4) having a high numeric aperture and, accordingly, leads to the best resolution capacity. Such measuring heads are insensitive to angular errors as concerns the orientation of the measuring head to the surface to be measured or to an oblique positioning of the surface relative to the optical axis of the measuring head.
