Abstract: 1. A data transmission arrangement for full-duplex transmission via a two-wire line between a central station and a substation, a transmission clock being generated in the central station, having a clock period in whose first half signal transmission is effected from the central station to the sub-station and in the second half signal transmission is effected from the sub-station to the central station, the signal transmission code being chosen such that the signal transmitted by the sub-station is synchronizable with the transmission clock, characterized in that the sub-station comprises an automatic, switchable clock pulse generator producing a sub-station clock pulse whose clock period deviates from the clock period of the transmission clock by a fixed amount, as long as the two clock periods are not in synchronism and that a phase comparator circuit controls the switchable clock pulse generator for the two clock periods.

Abstract: New compounds of the formula
     wherein B is a nucleoside or deoxynucleoside base; R is H or a blocking group, A is H or OR; R, is a hydrocarbyl radical containing up to 10 carbon atoms and X is a secondary amino group. The new compounds can be chemically bound to an inorganic polymer. The chemical bonding of the nucleoside moiety to the inorganic polymer is by means of reactive groups on the polymer which react with reactive groups of the nucleoside molecule. Such modified inorganic polymer supports are useful in the stepwise addition of nucleosides or oligonucleotides to the original nucleoside moiety of the support by a series of process steps. The starting nucleoside which is blocked in either the 3'- or the 5'-OH and the nucleoside is coupled through the unblocked hydroxy group to the polymer support by the coupling agent. Furthermore an automated apparatus for producing a modified silica gel which is an example of a modified inorganic polymer is shown.

Abstract: A hollow inner conductor (4), expediently having a relatively small diameter, is fitted in a preferably round waveguide (1). The inner conductor (4) has coupling elements, e.g. resonant slots (7, 8) coupling into its interior, at one or more points selected on the suitability of the field, the coupling elements being geometrically reduced with respect to such coupling elements which are also used, or can be used, on the wall of the waveguide - where their function is for external coupling. Having been coupled into the interior of the inner conductor, the wave is converted into a different line wave mode, e.g. the coaxial fundamental wave mode. The wave is then fed out into the space outside the waveguide (1) in this form. The wave mode filter according to the invention can be used as a directional wave filter, e.g. in satellite radio and radar technology, in which the wave mode to be coupled out, for example the H01-wave converted into the coaxial fundamental wave, is made use of to form the antenna deviation information and a further wave mode in the waveguide is used as the useful wave mode which carries the information. <IMAGE>

Abstract: Methods and apparatus are described for estimating shear wave slowness of formations traversed by a borehole from guided wave acoustic log data. Acoustic energy is generated at a point in the borehole and received at at least four receiver stations spaced one from the other and from the generating point. Full wave forms of the received signals are produced and windowed to identify guided wavelets. Fourier transforms of the guided wavelets are obtained and from these determined the phase velocity and frequency of the guided wavelet. Values of formation density, drilling fluid density, drilling fluid slowness and borehole diameter are measured and a value of Poissons ratio may be estimated. A multi-dimensional matrix is established comprised of predetermined ranges of assumed values of frequency, Poissons ratio, drilling fluid slowness, drilling fluid density, formation density, phase velocity and borehole diameter. The measured data is fitted to the multi-dimensional matrix to obtain an estimate of shear wave slowness at the point in the borehole, and the estimate is recorded as a function of depth.

Abstract: The known nuclear hydroxylation of phenol or substituted phenols or phenol ethers with organic solutions of hydrogen peroxide in the presence of a catalyst is carried out in improved manner by employing both (1) a special, practically water free solution of hydrogen peroxide in an organic solvent which forms an azeotrope with water, which azeotrope boils below the boiling point of hydrogen peroxide, and (2) selenium dioxide as a catalyst. Through this, the nuclear hydroxylation is substantially simpler than previously. Besides, for the first time, it is possible to control the ortho to para ratio or the two ortho ratios to each other.

Abstract: Bei einem Thermoschalter zur Temperaturüberwachung elektrischer Wärmegeräte ist die Kontaktzunge einstückig mit einer Anschlußfahne hergestellt und bis auf einen relativ kurzen Längenbereich starr, so daß bei Beaufschlagung der Kontaktzunge durch die Bimetall-Springscheibe eine scharnierähnliche Bewegung der Kontaktzunge erzeugt wird. Durch die einstückige, starre Ausgestaltung dieses als Anschlußfahne und Kontaktzunge wirkenden Bauteils lassen sich die geometrischen Bedingungen innerhalb des Thermoschalters, insbesondere der Abstand der Kontaktzunge von der Bimetall-Springscheibe sehr viel besser in engen Toleranzen halten als bei bekannten Blattfedern als Kontaktzunge. Hierdurch wird ein zuverlässigeres Schaltverhalten und damit eine Qualitätsverbesserung bei der Serienfertigung sowie eine Reduzierung der Herstellungskosten erreicht. Bei einer besonders einfachen Ausgestaltung ist vorgesehen, daß anstelle der Nieten, die zur Befestigung der beiden Anschlußfahnen am Trägerblock dienen, aus den Anschlußfahnen entsprechende Teile ausgestanzt und ausgeformt sind, so daß die gesamt Teileanzahl für den Thermoschalter auf vier Teile reduziert werden kann, wobei im Unterschied zu bekannten Lösungen die Bimetallscheibe keinen Kontakt trägt. Die erfindungsgemäße Lösung erlaubt auch in einfacher Weise eine Halterung und Führung der Bimetall-Springscheibe, die ein leichtes Einsetzen bzw. Auswechseln der Bimetall-Springscheibe in den fertig montierten Thermoschalter erlaubt.

Dabei wird vorgeschlagen, die Zeichenelemente (32) als in ihrer gesetzten Lage aus der Tafelebene vorspringende, kappenartige Noppen aus elastischem Material auszubilden, welche zum Löschen einstülpbar sind. Zum Setzen der Noppen dienen in Setzrichtung wirkende Stempel (34), zum Löschen eine sich auf der Lesetafel (20) abwälzende Löschwalze (40), welche mit die Zeichenelemente einstülpenden Vorsprüngen (44) besetzt ist. Da die Zeichenelemente in ihrer gesetzten und gelöschten Lage jeweils stabil sind, brauchen keine Mittel zum Halten der Zeichenelemente in diesen Lagen vorgesehen zu sein. Es müssen deshalb nicht jedem Zeichenelement Setzstempel zugeordnet werden, ein Stempel kann vielmehr nacheinander mehrere Zeichenelemente setzen, indem die Tafel an diesem Stempel vorbei bewegt wird oder umgekehrt.
