Abstract: In a method for treating sulphide-containing white liquor in a continuously operating electrolytic cell (1) having separate anode and cathode compartments (2 et 3, respectively) separated by a partially permeable barrier (6), white liquor is introduced into the anode compartment (2) of the cell (1), and an aqueous solution of alkali metal hydroxide is introduced into the cathode compartment (3) of the cell (1), so that sulphide is oxidised in the anode compartment (2), while at the same time alkali metal cations are transported through the barrier (6) into the cathode compartment (3), where water reacts to form hydroxide ions. An electrolytic cell suited for implementing the method is also disclosed.

Abstract: Multiple simultaneous uses of a multi-service digital receiver are made possible with a single practical analog-to-digital converter (38) by translating the various ser-vice bands in frequency to form a single, generally contin-uous composite service band in which substantial frequency gaps (6) between the different services are eliminated. Bandwidth requirements are further reduced by a bandfolding technique in which at least one service waveband is divided about an intermediate mixing frequency (Fmix), the divided portions are overlapped so that they collectively occupy a sub-waveband with a smaller bandwidth than the original band, and the mixing frequency (Fmix) is chosen such that user-selected frequencies do not interfere with other ac-tive frequencies.  Interference between non-selected active frequencies is permissible and simply ignored.

Abstract: Increased upstream bandwidth and reduced ingress noise in a shared hybrid fiber-coax transmission system (100) are obtained by modulating at least a portion of upstream signals received from subscribers to a high frequency band (e.g., 750-1000 MHz), thereby increasing the upstream bandwidth. The high frequency upstream signals are then digitally regenerated in the coaxial cable (200) plant prior to receipt at a fiber node (180). At the fiber node, the high-frequency upstream signals are again digitally regenerated and are then transmitted optically in a baseband digital format between the fiber node (180) and a head end ( 120). The digital regeneration of the high frequency upstream signals, and the optical transmission of such signals in a baseband digital format reduces the incidence of ingress noise.

Abstract: The present invention relates to a method by which an operation characteristic of a proportional electromagnetic control valve can be automatically measured in a short period of time.  For this purpose, in the operation characteristic measuring method of the present invention, when the proportional electromagnetic control valve to be measured is a proportional electromagnetic pressure control valve, at each step for measuring a pressure of a hydraulic circuit, the pressure is measured with a predetermined interval of time, the pressure is assumed to be stabilized at a point of time when a difference ~P between thus measured pressure value and the previously measured pressure value becomes a predetermined level e or less, and the measured pressure value at this point of time is employed as a pressure corresponding to a load current at this step.  The present invention is used at the time when an injection molding machine is inspected at its manufacturing site upon shipping and at the time when the injection molding machine is controlled while being actually operated.
