IPC: C01B3/50
Filed: 1979-03-06
Abstract: PURPOSE: To inexpensively and stably separate and recover hydrogen of high purity by filtering and separating the hydrogen formed by the docomposition of hydrogen sulfide by the separation system comprising bundling a multiplicity of porous hollow glass fibers of the specified outside diameter, film thickness and fine pore size.  
     CONSTITUTION: At the time of recovering the hydrogen formed through thermal decomposition of the hydrogen sulfide obtainable in desulfurization process, it is treated by the separation system comprising bundling a multiplicity of porous hollow glass fibers or ceramic hollow glass fibers of outside diameter 2mm or less, film thickness 0.8mm or less and fine pore sizes 20W200Å which are open at one end and are closed at the other end and series forming modules M 1 WM 6 . More specifically, the cracked gas from a cracking furnace 1 is treated in the modules M 1 WM 6  and high-purity hydrogen is recovered from R 7 . The non-permeated gas is collected at Q 1  and S is recovered in a condenser 18 or circulated to the cracking furnace 1 and is re-decomposed. The hollow bodies are larger in surface area per unit volume as compared to the tubular bodies of conventional methods and the diffusion amount of hydrogen may be considerably increased.

Abstract: PURPOSE:To enable measurement of dielectric constant, density, size, mass, etc. of the dielectric without any restriction to the shape of the dielectric or the like by providing conductor plates on the outer peripheries of the end parts of a pair of waveguide pipes whose opening ends are opposed to each other and thereby forming the dielectric sensor. CONSTITUTION:The dielectric sensor 1 is formed by fitting the conductor plates 3 on the outer peripheries of the waveguide pipes 2 whose opening ends are opposed to each other and by providing an aperture 4 through which the dielectric to be measured can be inserted between the conductor plates 3, while a microwave is passed into the pipes form one of the waveguide pipe 2, and the aperture 4 between conductor plates 3 is determined properly, whereby a kind of resonator is constituted. And, when a dielectric material having some dielectric constant is put into the aperture 4 between the conductor plates 3 forming the resonator, equivalent dielectric constant becomes higher than that before putting and the resonant frequency is shifted toward low level. Accordingly, when dielectrics having the same size but unknown dielectric constant respectively are put into the aperture 4, respective resonant frequency becomes known, the dielectric constant of the dielectric which is put in can be calculated, and when the dielectrics having the same dielectric constant but being different in size are put into the aperture 4 respectively, the sizes thereof are known.

Abstract: PURPOSE:To enable the monitoring of vacuum free from effecting influence on shut down performance by the start of discharge within a discharge tube, by connecting a discharge tube which starts a discharge at a higher vacuum than that within a vacuum interrupter to the vacuum interrupter with a communicating member. CONSTITUTION:One end of a discharge tube 1 is mounted to an upper end plate 22 of a vacuum interrupter VI through a pipe 2 so that internal pressure of the tube 1 will be the same that of the interrupter VI under a static condition. As the tube 1 is connected to the end plate 22 of the interrupter VI with the pipe 2, the potential of a pipe side end plate 12 of the tube 1 and the electrode 14 is the same as that on the high voltage size of the interrupter VI. In addition, the distance between the electrodes 14 and 15 in the tube 1 is set smaller than any vacuum gap within the interrupter VI. Therefore, when the vacuum of the tube 1 lowers, a discharge starts between the electrodes 14 and 15 to allow a discharge current to flow through circuit elements Z1 and Z2 and a specified voltage develops at a midpoint in the elements Z1 and Z2. A drop is vacuum of the interrupter VI can be detected by checking these voltages with a vacuum monitoring circuit.

Title: Power line carriage device

IPC: H04B3/54
Filed: 1981-02-26
Abstract: PURPOSE:To transmit a signal without any error by selecting a phase wherein there is no noise, by storing a phase wherein a noise is generated. CONSTITUTION:An HPF3 removes the fundamental wave of an AC power signal from the output of a transformer 2 to extract a data signal and a noise component. An amplifier 4 amplifies the output voltage of the HPF3, and a level detector 5 detects the noise component having a certain value or greater. A shift register 6 stores the detected noise corresponding to the phase of the AC power signal. For a power signal with, e.g., 50Hz, if a part obtained by dividing the one-cycle AC power signal by 40 has an noise, a ''1'' signal is stored in a stage which corresponds to the phase. The outputs of the 1st and 2nd stages 6-1 and 6-2 of the register 6 are read out through an OR gate 7, whose output is applied to a communication control circuit 8; when the output of the gate 7 has a ''1'', the phase which corresponds to it is expanded by one bit in the phase to inhibit the transmission of data.
