Abstract: A process for the production of hydrogen peroxide according to the anthraquinone process. According to the process certain alkyl substituted caprolactames are used as solvents, and particularly as solvents for anthrahydroquinones. The substituted caprolactames, which for example can be hexyl caprolactam and octyl caprolactam, give a very good solubility for anthrahydroquinones and also for anthraquinones. The compounds can be used as the sole solvent at the production of hydrogen peroxide or in combination with conventionally used solvents such as hydrocarbons.

Abstract: Apparatus for detecting a fundamental frequency in speech in a changing speech environment by using adaptive statistical techniques. A statistical voice detector (103) detects changes in the voice environment by classifiers that define certain attributes of the speech to recalculate weights that are used to combine the classifiers in making the unvoiced/voiced decision that specifies whether the speech has a fundamental frequency or not. The detector is responsive to classifiers to first calculate the average of the classifiers (202) and then to determine the overall probability that any frame will be unvoiced. In addition, the detector using a statistical calculator (203) forms two vectors, one vector represents the statistical average of values that an unvoiced frame's classifiers would have and the other vector represents the statistical average of the values of the classifiers for a voiced frame. These latter calculations are performed utilizing not only the average value of the classifiers and present classifiers but also a vector defining the weights that are utilized to determine whether a frame is unvoiced or not plus a threshold value. A weights calculator (204) is responsive to the information generated in the statistical calculations to generate a new set of values for the weights vector and the threshold value which are utilized by the statistical calculator during the next frame. An unvoiced/voiced determinator (205) then is reponsive to the two statistical average vectors and the weights vector to make the unvoiced/voiced decision.

Abstract: The method involves using a central unit with server with a first and second data bank, a transmitter/receiver unit for temporary news and an interface for radio exchange. A terminal has a position determining device for periodically determining the rough position data of the train and forwarding same so that the exact position of the train can be calculated by a correlation process in the central unit from the rough position data received and stored in the first data bank. This can then be sent to the interface for radio exchange. In the event of several stretches having normal distances which are less than the expected error in the rough measurement the train is located in a junction area whereby the stretch is determined with the drive plan stored in the first data bank. In the absence of a drive plan the stretch is determined by a frequency parameter.
