Abstract: Die Erfindung betrifft ein Messgeraet zur Untersuchung der Kinetik schneller chemischer Reaktionen in Loesung nach dem Temperatursprung-Relaxationsverfahren mit spektralphotometrischer Beobachtung des Reaktionsablaufs unter besonderer Beruecksichtigung der fluorimetrischen Messmethode. Nach der Erfindung wird bei einem Temperatursprung-Messgeraet, das fuer fluorimetrische und zweckmaessig auch fuer absorptionspektral-photometrische Messungen eingerichtet ist, die Messempfindlichkeit insbesondere dadurch entscheidend verbessert, dass im Emissionsstrahlengang ein immersionsoptisches Linsensystem mit extrem hoher Lichtstaerke verwendet wird, das den geometrisch-optischen Wirkungsgrad handelsueblicher statischer Spektralphotometer um das Vielfache uebertrifft. Dieses Linsensystem soll in geeigneter Kombination mit anderen, z. Zt. bekannten Massnahmen verwendet werden. Die hohe optische Effizienz der Messordnung macht es darueber hinaus moeglich, wahlweise polarisationsoptische Elemente in den Strahlengang zu bringen, wobei zwar Lichtverluste unvermeidlich sind, durch Messung der Fluoreszenz-Polarisation aber wertvolle zusaetzliche Information gewonnen werden kann, vor allem bei Bindungsstudien an makromolekularen Substanzen                                                                                                                                                                                                                                                          ...U.S.W

Abstract: A frequency standard for an electronic timepiece comprising a low frequency oscillator and a high frequency oscillator of which the frequency is an integral multiple of a predetermined frequency of the lower frequency oscillator. A phase difference detector is coupled to the lower and higher frequency oscillators to produce a signal occurring at intervals depending on the phase difference between the two oscillators. A frequency divider is provided to divide down the frequency of the signal by the integral multiple to produce a phase difference signal. The phase difference signal is algebraically added to the lower frequency oscillator signal to generate an output signal of which frequency is equal to that of the high or frequency oscillation signal divided by the integral multiple.
