Abstract: A method of producing an elastically deformable functional part for a medical device, devices for such methods, and a medical device having such a functional part. The functional part has an openable slit arrangement that widens or opens upon elastic deformation of the functional part and closes again in the absence of the deformation.

Abstract: The present invention relates to a measuring device (10) and a method for determining a depth of field of an optical structure (100). In this case, the measuring device comprises a device body (12) with a measuring axis (14), the device body (12) being formed such that, in a measuring position, it can be placed in a stationary manner on a deposit plane of the optical structure such that the measuring axis (14) of the device body (12) coincides with an optical axis of the optical structure, wherein the device body (12) has a measurement scale (18) arranged along a scale line (16) such that the scale line (16) encloses with the direction of the measuring axis (14) a scale angle ? greater than 0° and less than 90° and the measurement scale (18) can be optically detected in the measuring position of the device body (12) by the optical structure (100) for determining the depth of field.

Abstract: In a combination of a drum scanner and a loading magazine, the drum scanner includes a holding and rotating device equipped for holding an interchangeable copy cylinder firmly from below in an at least approximately upright position and for rotating it about a longitudinal axis thereof for scanning.

Abstract: An apparatus and method for automatically clamping film material onto the recording drum of a reproduction device and for releasing the film material exposed by a recording element from the recording drum. The apparatus has a roll film cassette introducible into a light tight portion of the reproduction device. Conveyor and guide surfaces are provided between the roll film cassette and the recording drum. Film conveying means is provided for conveying the film web situated in the roll film cassette to the recording drum. A film cutting means is provided for the separation of film sheets. A film length measuring means, a pressure means having a lowerable pressure roller for the film sheets, a positioning drive for turning the recording drum into a start of clamping, start of exposure and start of release position, and a lift-off means having a lowerable lift-off finger for peeling the exposed film sheets from the recording drum are all provided. The film sheets are fixed on the recording drum by vacuum.

Abstract: The invention is directed to a device for automatically clamping and releasing film material onto or, respectively, from the recording drum of a reproduction device with vacuum suctioning. The device is composed of a roll film cassette, of a conveying and guide surface, of a film cutting means, of a film length measuring means, of a pressure means having a pressure roller, of a lift-off means having lift-off finger, as well as drives for turning the recording drum and for conveying the film material to the recording drum. The recording drum comprises axially proceeding suction hole rows for suctioning the film material by vacuum. A vacuum distributor controllable by the rotational motion is arranged in the recording drum, this vacuum distributor successively connecting the individual suction hole rows to the stationary vacuum pump during clamping, so that the suction hole rows are charged with vacuum step-by-step with increasing wrap of the recording drum by the film material.

Abstract: This invention relates to a process for continuously preparing a web of thermoplastic flat film for a subsequent winding operation, by providing it with embossed lines, preferably one line along each edge or very near each edge of the web, which process comprises embossing the lines while the film web is in a thermal state in which the tensioned film may be easily embossed, and is tensioned in all directions without undergoing a stretching operation effecting a dimensional change of the film web, and then cooling the embossed web of film.

Abstract: A method and apparatus is disclosed for the automatic and rapid recognition of faults in a surface or dimensions of an object, or for recognizing a position of the object in a field of view of an observation and/or measuring device. A photodiode row is provided having an active surface with a length dimension substantially greater than its width dimension. An anamorphotic lens system is provided which focuses a first dimension of the field of view onto the active surface length dimension and which focuses a second orthogonal dimension of the field of view onto the active surface width dimension. By means of signals from the photodiode row, theoretical dimensions can be compared with actual measured dimensions of the object.
