Disclosed is an apparatus for providing packaging material, comprising a shaping device (25) that has a couple of motor-driven molding wheels or rolls, a housing support (15) with an interior, an inlet via which packaging material can be fed into the interior, and an outlet via which packaging material can be discharged from the interior in which the molding wheels are arranged. The molding wheels are rotatably mounted on the housing support and each define an axis of rotation. A continuous penetration shaft (23), the longitudinal direction of which extends substantially parallel to the two axes of rotation of the molding wheels, from the interior to the exterior of the housing support, is formed withing the housing support, said penetration shaft (23) being open towards the interior and towards an exterior of the housing support.

In a method for monitoring the hitch of at least one trailer, which is pitchable to a tow vehicle, the tow vehicle having a steering system with which a steering angle is settable, the following steps are performed: a) detecting yaw oscillations of the tow vehicle over a certain period of time, e.g., 1 second to 3 seconds, at a constant or almost constant steering angle and above a predefinable speed of the tow vehicle without brake intervention, and b) evaluating the detected yaw oscillations for whether the amplitudes of the yaw oscillations do not fall below a predefinable amplitude threshold.

An apparatus for shaping packaging material, comprising a housing support including hopper, a packaging material reservoir, a discharge orifice, and a bearing structure therebetween defining a continuous feeding path for the packaging material. The feeding path includes an interior wall continuously extending around an axis of the material's feeding direction. The housing support further includes at least one concavity in the bearing structure extending laterally away from the feeding path, the concavity having a portion within the feeding path at a slit formed within the interior wall, the concavity holding a shaping device that is rotatably mounted on the bearing structure and partially projects from the slit into the feeding path, the shape of the slit being complementary to the shape of a section of the shaping device adjoining the slit such that a tolerance gap is formed allowing the shaping device to rotate relative to the bearing structure.

A measuring unit set up to determine a relative position and relative orientation between the measuring unit and an arrangement of at least three optical elements. The measuring unit comprises a length measuring device, which emits measuring beams at at least three locations spaced apart from one another, and at least one beam directing device set up to direct the measuring beams to optical elements of the arrangement. The beam directing device is controllable in order to guide at least one of the measuring beams to a plurality of optical elements of the arrangement in a time-sequential manner in order to carry out a plurality of length measuring operations in a time-sequential manner in such a manner that, in the plurality of length measuring operations, each measuring beam of the at least one measuring beam strikes precisely one of the optical elements. A total of six lengths are measured in this manner.

Disclosed is a housing support for an apparatus that is used for providing packaging material. A device for shaping the packaging material in order to form filling material this is discharged at an outlet of the housing support is rotatably mounted on the housing support. The housing support comprises a hopper on which a holder for a packaging material reservoir can be mounted and via which the packaging material is fed to the shaping device, a discharge orifice that delimits the outlet, and a bearing structure which is arranged between the hopper and the discharge port in the feeding direction and on which the shaping device can be rotated. The hopper, the discharge port, and the bearing structure are arranged to rest against each other in such a way that a continuous feeding path encompassing an especially rectilinear axis of the feeding direction is formed through the housing support. The feeding path is delimited by an interior wall in the region of the hopper and the discharge port, said interior wall continuously extending around the axis of the feeding direction. In said housing support, (a) at least one concavity that laterally extends away form the feeding path is provided in the region of a central interior wall of the bearing structure, said central interior wall delimiting the feeding path, (b) the concavity runs into the feeding path at a slit that is formed within the central interior wall, (c) the concavity holds the shaping device that is rotatably mounted on the bearing structure in such a way that the shaping device partially projects from the slit into the feeding path in order to shape the packaging material, and (d) the shape of the slit is complementary to the shape of a section of the shaping device adjoining the slit such that a tolerance gap is formed which allows the shaping device to rotate relative to the stationary bearing structure without entering in contact therewith.

An apparatus for determining and/or monitoring at least one process variable of a medium. The apparatus includes: at least one mechanically oscillatable unit; at least one transducer unit, which excites the mechanically oscillatable unit to mechanical oscillations based on an exciter signal and which receives the mechanical oscillations of the mechanically oscillatable unit and converts such to a received signal. The transducer unit has at least one piezoelectric element. The apparatus further includes: at least one electronics unit, which supplies the transducer unit with the exciter signal and which receives the received signal from the transducer unit; and at least one compensation element, which supplies the exciter signal to the electronics unit and from which the electronics unit receives a compensation signal. The invention provides that the compensation element has at least one at least element made at least partially of a piezoelectric material.

An implantable product includes an optical cavity structure with first and second parts, each of which can operate as an optical cavity. The first part includes a container with at least one opening through which bodily fluid can transfer between the container's interior and exterior when the product is implanted in a body. The second part includes a container that is closed and contains a reference fluid. The implantable product can also include one or both of a light source component and a photosensing component. Photosensed quantities from the first part's output light can be adjusted based on photosensed quantities from the second part's output light. Both parts can have their light interface surfaces aligned so that they both receive input light from a light source component and both provide output light to a photosensing component.
摘要:
A technique for creating high quality Schottky barrier devices in doped (e.g., Li+) crystalline metal oxide (e.g., ZnO) comprises field-controlled diffusion of mobile dopant atoms within the metal oxide crystal lattice. When heated (e.g., above 550 K) in the presence of an electric field (e.g., bias to ground of +/−50 V) the dopant atoms are caused to collect to form an ohmic contact, leaving a depletion region. The size of the depletion region controls the thickness of the Schottky barrier. Metal-semiconductor junction devices such as diodes, photo-diodes, photo-detectors, MESFETs, etc. may thereby be fabricated.
