    摘要： In data transmitting systems, an apparatus for synchronizing the frame clock in units/nodes. The apparatus has a phase detector and a voltage controlled oscillator. At least one input of the phase detector is supplied with an incoming clock signal and another input is supplied with an output signal of the voltage controlled oscillator. The output signal of the voltage controlled oscillator is conducted over a divider, which is connected to a frame clock phase detector for setting its division factor. The frame clock phase detector is supplied with an input frame clock, the output of the variable divider, and at least one output of an output divider. The at least one output of the output divider divides the output signal of the controlled oscillator into the output frame clock. The frame clock phase detector is configured for the output of a pulse that temporarily raises or lowers the division factor of the divider when the phase difference between input and output clock deviates from a prescribable quantity.

    摘要： A method and an arrangement for controlling modulated lasers are provided, in which an input signal of a laser is modulated by a pilot signal. The combined signal that is emitted is then utilized to control the laser. In order to substantially prevent individual spectral lines of the input signal from affecting the pilot signal, a pilot signal is selected with a frequency spectrum that is spread substantially uniformly in the spectral range of the input signal. Versions of this method are also known by the term “spread spectrum modulation”.

    摘要： Isocyanate-based foams are produced by the reaction of polyisocyanates with compounds with molecular weights of from 400 to 10,000 and having at least two hydrogen atoms active towards isocyanates in the presence of hydrocarbons which are vaporizable under the foaming conditions as blowing agents. The active hydrogen component is a mixture of a) one or more nitrogen-free polyethers having at least two hydrogen atoms active towards isocyanates and containing oxyethylene residues, and b) one or more polyethers having at least two hydrogen atoms active towards isocyanates and containing no oxyethylene groups.

    摘要： A process is provided for the production of synthetic polyurethane plastics, particularly foam plastics, containing biuret groups by reacting polyisocyanates, polyhydroxyl and/or polycarboxyl compounds, flame inhibitors and, if desired, blowing agents, emulsifiers, activators and other additives which is characterized by using as the polyisocyanate solutions in monomeric polyisocyanates of from about 1 per cent to 85 per cent of polyisocyanates containing biuret groups and having the formula: ##EQU1## in which R is an aromatic, araliphatic or cycloaliphatic radical which may, if desired, be substituted andn is an integer from 0 to 5, wherein the proportion of biuret-polyisocyanates having more than three isocyanate groups is at least 20 per cent by weight based on the total quantity of biuret-polyisocyanates, and the solutions contain from about 0.03 per cent to about 5 per cent by weight of chemically combined emulsifiers.
