Abstract: A holding device for spherical and flat objects includes a carrier body, a clamping device held to the carrier body, a cover plate held to the carrier body, a plurality of holding elements, and an axle accommodated by the holding elements. The clamping device includes first and second clamping elements for accommodating round or angular objects. The cover plate and carrier body are partially spaced-apart to provide a guide slot, and at least one of the carrier body or the cover plate includes retention elements including formed lips extending from a basic body, each lip including an uninterrupted front edge. The cover plate is pivoted in a tiltable manner around the axle to connect the cover plate with the carrier body and is held under tension of a torsion spring against the carrier body. The cover plate is also formed so as to allow a tilt motion against the force of the spring to open the guide slot.

Abstract: A low-cost single-sided NMR sensor to produce depth profiles with microscopic spatial resolution is presented. The open geometry of the NMR sensor provides a non-invasive and non-destructive testing method to characterize the depth structure of objects of arbitrary size. The permanent magnet geometry generates one plane of constant magnetic field intensity parallel to the scanner surface. By combining the highly uniform static gradient with selective RF excitation, a thin flat sensitive slice can be defined. By moving the relative position between the slice and the object, one-dimensional profiles of the near surface of large samples are produced with high spatial resolution.

Abstract: A modular wiring system comprising a functional unit and a wiring unit. There is also a system for coupling the functional unit to the wiring unit in a rotational manner. This system can be formed from at least one locking prong comprised of electrically conductive material. When the functional unit is coupled to the wiring unit, the locking prong is both electrically and physically coupled to the functional unit at a first end and to the wiring unit at a second end. Alternatively, or in addition, the system for coupling the functional unit to the wiring unit in a rotational manner can include at least one flange coupled to the functional unit and at least one flange coupled to the wiring unit. These flanges operate such that when the functional unit and the wiring unit are coupled together, they are rotated to form a locking connection between the flange on the functional unit and the flange on the wiring unit.

Abstract: The invention relates to a pole terminal for producing an electrical connection. Said pole terminal comprises a metallic conductive body which is surrounded by an insulating body which can be fixed to the housing of an electrical appliance, and on which a tensioning nut can be screwed, said tensioning nut clamping the electrical conductor to be connected against the conductive body, establishing an electrical contact. The aim of the invention is to improve one such pole terminal in such a way that the conductive body can be produced from a material which is highly conductive, such as silver or copper. To this end, the conductive body is produced from a material exhibiting higher conductivity, by means of noncutting deformation, and is connected to the surrounding insulating body to form a composite body. Preferably, the conductive body is embodied as a stamped part which is machined by bending strain.

Furthermore it is possible to carry out the charging of the capacitors in a programmed manner, and the charging voltage of the capacitor bank is fixed and independent of the supply voltage, the equipment being able to operate automatically at a voltage between 90 and 264 volts.

Abstract: The invention relates to a plate spring that is prevented from being axially displaced on a surface of a receiving body, the surface being circular cylindrical at least in areas. The aim of the invention is to provide a plate spring of the aforementioned type that is able to maintain a securing against axial displacement with the least amount of effort. This is achieved by virtue of the fact that the edge of the plate spring radially facing the receiving body engages inside a peripheral groove provided in the receiving body.

Abstract: A buckle having a male portion and a female portion. The male portion has two sidewalls, first and second retaining bars and at least one locking arm. There is a slidable and pivotable strap gripping bar disposed adjacent the first strap retaining bar. The strap gripping bar is adapted to slide between a release position and a gripping position. The female portion comprises a hollow body with an open end and at least one locking slot for receiving the locking arm. When the male portion is inserted into the female portion, the locking arm locks into the locking slot and the female portion pushes the strap gripping bar into a gripping position, which grips a strap threaded through the retaining bars, and prevents the strap from slipping. When the male portion is released from the female portion, the strap gripping bar slides into the release position and allows adjustment of the strap.
