Abstract: The present invention provides a process for the continuous production of chlorine dioxide by the reaction of hydrochloric acid with an alkali metal chlorate solution, which is obtained by means of an electrolysis plant from a chlorate solution containing alkali metal chloride circulating in the process, together with cathodically-formed hydrogen, in a cascade reactor with the introduction of air, wherein the reaction of the alkali metal chlorate solution with the hydrochloric acid is carried out under reduced pressure and chlorine gas separated off from the reaction product is reacted with the cathodically-formed hydrogen with the introduction of external chlorine gas to give the required amount of hydrochloric acid. The present invention also provides a device for carrying out this process, comprising at least one chlorate electrolysis plant, a cascade reactor, a separation column and a hydrochloric acid synthesis furnace, which are connected with one another by means of pipes according to the manner of operating the process, wherein a valve is provided in the air inlet pipe of the reactor, which valve is regulated corresponding to the pressure at the product outlet of the reactor.

Abstract: An automatic fingerprint enrollment and identification technique is provided for automatically processing an input image represented by pixels having either a one or a zero value. The automatic processing involves a series of steps in which the initial processing is a rough screening technique for eliminating a reasonable portion of the noise while passing through almost all of the minutia. As the steps proceed, the processing becomes more complex to provide a tighter screening out of noise while passing through as much of the minutia as possibe. The later steps by operating on relatively fewer minutia or anomaly points that the earlier steps can be economical though more complex so as to be more discriminate than the earlier steps. The processing provides an optimum trade off between enrolling as large a proportion of the population as possible while minimizing the number of false identification errors.

Abstract: In a method and apparatus for coding of digital signals, especially so-called "waveform" coding of voice frequency signals to reduce bit rates for reduced transmission or storage requirements, in which, for each block, an excitation signal is derived which, when applied to be a synthesis filter having suitable LPC coefficients, will generate an approximation to the input signal, low signal delay is achieved by deriving such excitation signal using the LPC coefficients corresponding to the last sample period of the corresponding block. Thus the excitation signal calculations in the encoder need only be delayed by the duration of the block. The LPC coefficients can be derived on a continuous or sample-by-sample basis using an adaptive lattice. Simplified computation of the excitation signal, which comprises a set of pulses fewer in number than the number of samples in the original block, may be achieved by cross-correlating the impulse response of the modified synthesis filter with the output of the filter and using the result, together with the covariance of the impulse response, to derive the parameters of the excitation pulses. Further computation simplifications may be achieved by using an auto-correlation as the covariance signal.

Abstract: A method for hydrolyzing coffee extraction residue materials to produce manno-saccharides having a degree of polymerization from 1 to 10 and subsequently neutralizing and reducing said mixture of manno-saccharides to their corresponding alcohols. The coffee material, preferably spent coffee gounds from a commercial percolation system, is hydrolyzed in a Plug Flow tubular reactor in the presence of an acid catalyst, such as sulfuric acid. Depending on the time, temperature, pressure and catalyst concentration selected, manno-saccharide or mannose is produced. The manno-saccharides or mannose produced are separated from coffee residue material in the form of a syrup and neutralized with calcium hydroxide. The neutralized mixture of manno-saccharides or mannose is reduced to their corresponding alcohols or mannitol.

Abstract: An improved ECL circuit in which reference voltages have been eliminated is provided. The base of the reference switching transistor which is usually connected to a reference voltage is instead connected to the emitter of an emitter follower transistor coupled to the input switching transistor. The need for a reference voltage is thus eliminated because the emitter of such emitter follower transistor, and thus the base of the reference switching transistor, will be at the opposite level of the input to the base of the input switching transistor.

Abstract: Method and apparatus for detecting when a collision occurs between two or more binary data signal packets at a single binary data signal receiver. Whenever a packet is transmitted, a large signal impulse is substituted for the initial bit of the packet. The amplitude of the impulse is such that it is significantly greater than the highest binary signal level transmitted. The receiver recognizes the impulse not as a data bit but as an indication of the beginning of a packet. Every packet has a known duration (or packet period) and is separated from the next packet by at least a known gap period. If two impulses are received within a period less than or equal to the sum of the packet and gap periods, a collision has occurred and a packet collision signal is generated.

Abstract: A spinning nozzle plate having nozzle capillaries is produced by depositing a layer 11 of a material whose characteristics can be changed by high-energy radiation (resist material) on a galvanic electrode 12. After resist layer 11 is irradiated in a predetermined pattern and after resist material is selectively removed by a treatment which utilizes the different material characteristics resulting from the irradiation, columns of resist material remain on galvanic electrode 12 to serve as negatives 21 of the nozzle capillaries. A galvanic layer 31 which encloses the negatives 21 of the nozzle capillaries is then produced on the galvanic electrode 12. Then the galvanic layer 31 is levelled and the negatives 21 are removed, as is the galvanic electrode 12. The process is particularly useful for producing spinning nozzle plates having nozzle capillaries with profiles of a special shape, essentially if the cross-sectional dimensions of the nozzle capillaries are small.
