Abstract: In an apparatus at a spinning preparation machine, especially a carding machine, opener, cleaner or the like, an axle, a bearing or the like is fixed in a stationary mounting element by a fastening element. In order to allow, in simple manner, precise adjustment of the axle, the bearing or the like in an axial direction and especially to allow displacement by a small amount, the fastening element is arranged between the curved surface of a body, for example, an axle, bearing or the like, and an internal surface of the mounting element, and is capable of fixing the body by a clamping force and, without the clamping force, is capable of allowing the axle, the bearing or the like to move.

Abstract: An apparatus on a spinning preparation machine for monitoring and/or adjusting clearances at components has a clothed, high-speed roller located facing at least one clothed and/or unclothed component and the clearance between the components facing one another is alterable. The roller and opposed component(s) are electrically isolated with respect to one another and are connected as contact elements to an electrical power supply line in which a measuring device for ascertaining contact is located. In order to avoid an undesirably heavy contact between the components, electric signals are emitted upon contacts with the clothing of the roller and the measuring device is arranged quantitatively to determine the contacts.

Abstract: Wire-untwisting tools and tool bits are disclosed. The wire-untwisting tool comprises a tool body, a movable member, and a spring. The tool body has a first channel extending inwardly from a first surface and a second channel extending inwardly from a second surface. The movable member includes a third channel, and is positioned within the second channel to move therein between an open position, in which the first and third channels are substantially aligned and contiguous, and a gripping position, in which they are not. The spring bears between the tool body and the movable member so and biases the movable member toward the gripping position. A pair of twisted wires inserted into the aligned channels of the tool body and the movable member when the movable member is pushed into the open position will be gripped for untwisting when the movable member moves back to the gripping position.

Abstract: The invention relates to a universal joint comprising two joint yokes and a cross member. One of the joint yokes is connected to a driven shaft or drive shaft, the other joint yoke being connectable or connected to the shaft to be driven or driven shaft. The two joint yokes are arranged twisted radially at an angle of 90° in relation to each other so that the two joint yokes form an internal space, in which the cross member is disposed. The cross member is formed of two separate pin bearers arranged orthogonally in relation to each other which are pivoted in the respectively associated joint yokes. The pin bearers crossing each other are rigidly connected with each other. The pin bearers with their pins that are arranged, respectively, at the end sides are pivoted in the associated joint yoke or in its yoke arms via bearings. The radially opposing bearings of the respective joint yoke form a pair of bearings, respectively.

Abstract: Digital pictures are taken by a digital camera. The digital camera provides picture data with a large dynamic range of, for example, 10 bit. Data processing and display devices operate with 8 bit only, i.e. do not take advantage of the high dynamic range of the camera. This is important in traffic monitoring installations, where, on one hand, the driver in a relatively dark passenger compartment of a vehicle and, on the other hand, the bright license plate have to be recognized to provide evidence in court. For this reason, a dark picture and a bright picture are derived from the picture data provided by the camera. This is done by reading, on one hand, the eight least significant digits and, on the other hand, the eight most significant digits of the camera output to provide the dark and bright pictures, respectively. The dark and bright pictures thus obtained are balanced against color, gray, contrast or brightness values of histograms derived from previous pictures.
