Title: Device for securing tape-guiding elements in a magnetic tape apparatus
Inventor: GUKKENBERGER HORST DIPL ING
IPC: G11B15/665
Filed: 1988-04-15
Abstract: A description is given of a device for securing tape-guiding elements in a magnetic tape apparatus, in particular in an apparatus for digital sound recording, the magnetic tape apparatus operating by the so-called helical scanning process. The magnetic tape is drawn out by tape-guiding elements (5/6) from a magnetic tape cassette (2) and laid partially around a rotating head drum (4). The tape-guiding elements, which preferably comprise a tape-guiding roller (14) and a tape-guiding pin (15), are mounted on a sliding shoe (7/8). This sliding shoe is designed in such a way that the tape-guiding elements are only brought into the predetermined angular position with respect to the head drum after reaching their end position, by the sliding shoe bearing against a stop pin (12/13). An essential aspect here is that the supporting faces (16, 16', 16'') of the sliding shoe, which form the exact end position, come to bear only on the surface of the apparatus chassis (11), since this chassis surface represents the reference plane for all the major functional elements of the apparatus. <IMAGE>

Title: Electric heating register (radiator)
Inventor: HILLINGER ERICH
IPC: H05B3/32
Filed: 1988-08-12
Abstract: Electric heating registers for heating gaseous media preferably operate in relatively high temperature regions so that it is necessary to provide safety devices which prevent damages occurring due to overheating. Devices of this kind, however, make the corresponding apparatuses more expensive. Therefore, the object is addressed of creating a heating register which, similar to the heating cartridges which are equipped with PTC thermistor heating elements and used only in low temperature regions, has a self-regulating effect which reliably prevents overheating. This object is achieved in that the heating conductor is manufactured from an alloy of nickel, whose coefficient Tk of temperature is larger than 200%. <IMAGE>
