Patent DE-3142567-A1 (DE)
Title: Process for the production of thin glass layers
Inventor: KANDACHI TAKAYOSHI
IPC: C03B18/06
Filed: 1981-10-27
Abstract: A process is indicated for the production of thin glass layers by the flotation method, in which a thin glass melt layer is produced by causing a glass melt to flow through a gap formed on the surface of a metal melt bath, and drawing or stretching the glass layer in the longitudinal direction of the bath in order to further reduce the thickness and to remove the glass layer while its upper surface is exposed to a cooled environment. A thin gap is used between the surface of the metal melt and a lower end surface of a wall which extends in the transverse direction above the metal melt bath. By means of a particular shaping of a lower end section of this wall, and since particular heating of the glass melt in the vicinity of the gap is avoided, it is possible to produce glass layers having a thickness of less than 1 mm with virtually no flaws.

Title: Apparatus for recording and reproducing frequency-shift-keyed voice-frequency telegraphy signals on a magnetic tape recorder
Inventor: PLATA HANS VON DIPL ING
IPC: G11B20/06
Filed: 1982-12-07
Abstract: To reduce the unwanted frequency swing due to synchronisation inconstancy on magnetic tape recorders (1), a pilot tone of n times or 1/m times the frequency of the signal mid-frequency (n and m > 1) is entered in the said recorder on the recording side in addition to the frequency-shift-keyed voice-frequency telegraphy signal which is actually to be stored. On the reproduction side, the pilot tone signal taken from the recorder and filtered out is divided in terms of its frequency by the factor n or multiplied by the factor m and fed to the first input of a mixing stage (6), in the second input of which a signal is entered which is made up of the filtered-out voice-frequency telegraphy signal taken from the recorder and the signal mid-frequency additively mixed with it. The differential signal in terms of frequency at the output of the mixing stage forms the voice-frequency telegraphy signal substantially freed of the unwanted frequency swing caused by the synchronisation inconstancies of the magnetic tape recorder. The apparatus according to the invention is suitable for magnetic-tape intermediate storage of frequency-shift-keyed (F1) voice-frequency telegraphy signals. <IMAGE>
