Abstract:
The invention specifies a holding apparatus comprising a support element and a circuit board. A trench for receiving the circuit board is embodied in the support element. At least one first clamping element is arranged on one or both longitudinal sides of the circuit board and/or at least one second clamping element is arranged in the trench. As a result, the circuit board received by the trench is fixed in the trench in a clearance-free fashion.
Abstract:
An apparatus and a method for changing printing plates in sheet-fed rotary printing presses include a plurality of printing units and plate cylinders being coupled to one another mechanically in the printing units during a printing operation. At the beginning of a plate change, the plate cylinders are coupled to one another mechanically and are driven jointly by a main drive motor. After an old printing plate has been conveyed out, each plate cylinder is decoupled from the common mechanical connection and is driven by a separate drive motor.
Abstract:
A transmission device is provided. The transmission device is operable to transmit data between a rotor and a stator. The transmission device includes at least two pairs of transmission units with one transmission unit embodied as a transmitter and one as a receiver.
Abstract:
A dust extractor device of a router has rotatable dust trap part able to be connected with a foot plate of the router and arranged to the side of the routing tool underneath the foot plate, such dust trap part being open toward the routing tool. The foot plate has an access opening for the routing tool. The dust trap part is constituted by an extractor hood with a hood casing at least essentially centered on the axis of rotation and a hood floor. The hood casing and the hood floor extend in the peripheral direction through an angle equal to or less than 180°. The extractor hood is open at its top side and opens into the access opening. The top end region of the extractor hood is rotatably supported on a holder, which is detachably secured to the foot plate and in the position of use extends around the access opening. The top side of the access opening is provided with a covering means, which is detachably attached to the foot plate and covers the access opening, such covering means having in it an access opening for the routing tool. The connection means is, in the position of use, in open connection with the access opening.
Abstract:
Devices for providing optical signal transmissions between a transmitter unit and a receiving unit which is mobile relative to the transmitter unit. The units are optically coupled to each other via an optical transfer medium, and thus improve transmission quality by eliminating, or greatly reducing interferences that affect the transmission quality.

Abstract:
The invention relates to a method for adjusting an optical rotating data transmission device having two units that are rotatable with respect to each other about a rotation axis, and that each have a coaxial collimator for coupling light in or out, and relates also to an optical rotating data transmission device that is adjustable by means of the method. For an adjustment, a deviation of a light beam from the rotation axis is determined by means of two detectors at different distances, and from this a positional deviation and also a tilt of the light beam is calculated and suitably compensated.
Abstract:
An apparatus for transmitting data at high data rates, between two systems that move relative to one another is provided. The apparatus includes an optical fiber and an axial module on one of the two systems for the purpose of axial data coupling, using the optical fiber and a lateral module on another of the two systems for the purpose of lateral data coupling using the optical fiber.
Abstract:
In a device of the invention for transmitting modulated optical signals between a first unit and a second unit, the first unit is supported to be rotatable relative to the second unit. The device comprises a light guide along a circular track on the first unit, a first light coupler for coupling light into or out of the light guide, and a second light coupler for coupling light into or out of the light guide and disposed on the second unit and movable relative to the means for guiding light. For an achievement of a high quality of transmission, a regulating means for the position of the coupling elements relative to the light guide, or a hydrodynamic bearing means is provided. An optical light-guiding fiber of the invention for conveying optical signals from an optical transmitter to an optical receiver has a light exit face and means for deflecting light emerging from the fiber in a direction that deviates from a longitudinal axis of the fiber.
Abstract:
The present invention relates to a communication station (MT; FIGS. 1, 2; FIGS. 3, 4) including a power supply unit (6, 6′, 6″), a core unit (1) connectable to the power supply unit (6, 6′, 6″) and constituted by a mechanically rigid assembly (9-14, 15-1, 15-2, 16-20) of all other electrical units of the communication station except for the power supply unit, and a shell unit (2-6) which houses the core unit (1) and comprises no electrical units of ther communication station. Front and back housings of the shell unit can be exchanged easily, since no electrical connections are necessary to the core unit during the exchange. Thus, differently shaped communication stations can be easily achieved from a variety of differently shaped housings.
