摘要:
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.
摘要:
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.

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.

A measuring unit is 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.

A method and system for using spatially modulated excitation/emission and relative movement between a particle (cell, molecule, aerosol, . . . ) and an excitation/emission pattern are provided. In at least one form, an interference pattern of the excitation light with submicron periodicity perpendicular to the particle flow is used. As the particle moves along the pattern, emission is modulated according to the speed of the particle and the periodicity of the stripe pattern. A single detector, which records the emission over a couple of stripes, can be used. The signal is recorded with a fast detector read-out in order to capture the “blinking” of the particles while they are moving through the excitation pattern. This concept enables light detection with high signal-to-noise ratio and high spatial resolution without the need of expensive and bulky optics.

An apparatus for determining and/or monitoring a process variable. The apparatus includes a housing, a mechanically oscillatable unit, and a transducer unit, which is arranged and clamped between two housing elements in such a manner that a predeterminable pressure acts on the transducer unit along an imaginary axis. An equalizing element is provided, whose coefficient of thermal expansion and/or height are/is selected in such a manner that a temperature-related expansion of the equalizing element during a temperature-related expansion of a housing element to be compensated leads to the pressure acting on the transducer unit being greater than or equal to a predeterminable prestress limit value.

In an embodiment a method for position determination of an object (25) in a spatial area (28) is provided in which the object (25) is illuminated with at least one light beam (22, 27). The light beam (22, 27) does not cover the complete spatial area (28) and is guided into a part of the spatial area in which the object (25) is present depending on the position of the object (25). In another aspect a method for measuring a surface is provided.

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.

A semiconductor device has a heterostructure including a first layer of semiconductor oxide material. A second layer of semiconductor oxide material is formed on the first layer of semiconductor oxide material such that a two dimensional electron gas builds up at an interface between the first and second materials. A passivation layer on the outer surface stabilizes the structure. The device also has a source contact and a drain contact.
