In a method for connecting at least two rods, wherein a binding apparatus, which is provided with a rotatable hook member, seizes a wire loop, which extends around the rods, and twists the loop during a pulling movement. The wire clamp or clip which has leg portion ends provided with locking means is brought around the rods to be connected in such a manner that, when viewed from the hook member the locking means are brought into engagement with each other behind the rods, and the closed wire clamp in front of the rods is seized by the hook member of the binding apparatus and twisted.The device is required for this purpose includes a binding apparatus which has a slide member connected to a displaceable gripping member for the forward advancement of the wire clamp and closing jaws which are adapted to bring the locking members on the wire clamp into engagement behind the rods to be connected.In this method and with this device, it is possible to achieve a connection between two reinforcement steel roeds in one working operation, by a forward-pushing movement and a backward-pulling movement, so as to eliminate the complicated process of inserting the binding wire behind the rods to be connected. This method in particular, considerably facilitates the work on the ground. The method also permits less specialized personnel to be used and, in addition, is quicker than conventional methods.

The present invention describes a light-sensitive copying material comprising a support and a light-sensitive layer which contains from 0.01 to 10 percent by weight of a non-ionic ester which is obtained by reacting a perfluoro-carboxylic acid with a polyalkylene glycol or of an ether which is obtained by reacting a highly fluorinated or a perfluorinated alkanol with a polyalkylene glycol. By the addition of the fluorinated compound, a more uniform coating is achieved, even when one solvent alone is used for the coating solution.

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.

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).

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.

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.

A measuring device (1) for measuring the shape, contour and/or roughness of a workpiece is based on a contact-less optical probe having a large numeric aperture. The probe has at least two different focal points with which at least two photo receptors are associated. The latter generate a differential signal for controlling a positioning device (13) for tracking the optical probe in such a manner that the workpiece surface is maintained within the measuring range of the probe. The differential signal is proven to result in a rapid and accurate tracking of the position of the sensor arrangement (3).

A method and apparatus for producing selectively collated print products employ a production section, a control device, a transfer-out device for transferring out defective print products, a detection device that detects and records gaps resulting from the transfer out of defective print products, and a transfer-in device. Initially, a line of print products are processed in a production section; a predetermined number of print products are diverted from the production section and supplied to a product buffer. If the print products are not diverted, the line of print products continue in a conveying section and gaps between the print products are detected and recorded via the detection device. A number of print products are removed from the product buffer based on a control signal from the control device to fill detected gaps between print products in the conveying section; and the removed print products are inserted into the recorded gaps.

A seat cross-member is provided in a vehicle with at least one platform, including longitudinal and cross-members as well as a center tunnel and chassis side members. The seat cross-member includes two profiled partial cross-members that are fastened at least on end sides to the longitudinal members and that, in the region of the center tunnel, are connected together, on the one hand, by at least one connecting element and, on the other hand, by the center tunnel. The connecting element has a bracket for a bearing of a drive shaft.
