Abstract: In this process and this device, air and/or pure oxygen is passed into the waste water in an aeration tank in the presence of biomass which is immobilised on carrier particles, and the waste water is subsequently separated into purified water and activated sludge in a secondary sedimentation. Since the biomass in the core of the carrier particles dies off gradually, the invention provides acceleration and slowing-down devices which allow regeneration of the carrier particles. In this process, the carrier particles are accelerated and then slowed down, so that according to the kinetic energy which is set free, a compression of the carrier material in some parts and therefore a loosening and partial elimination of the dead biomass are achieved. The biomass concentration in the carrier particles can be controlled by changing the speed at which they leave the accelerating zone. (Figure) <IMAGE>

Abstract: A plasma gun has a hollow generally cylindrical anode nozzle member and coaxially disposed therein a cylindrical cathode member, the members co-acting to form an interior passage for plasma forming gas. At one end, within the body of the gun, the passage comprises an annular gas inlet chamber or plenum proximate to the cathode. Progressing in the direction of flow, the passage is defined as an annular space between the cathode and anode members and then continues through the anode nozzle member to the exterior of the gun body. Plasma-forming gas is introduced inwardly through respective inlets, tangentially and radially into the gas inlet chamber. Means are provided for selectively regulating the respective amounts of gas introduced radially and tangentially to thereby determine the degree of vortical flow of gas through the gun.

Abstract: A modified liquid polymer is produced by reacting in the presence of a catalyst at least one mercaptan-terminated liquid polymer having functional linkages in the backbone with an amount below stoichiometry of at least one multi-functional cross-linking agent having mean or average functionality greater than 2. The amount of the cross-linking agent(s) is calculated by stoichiometry such that between 1 and 60 per cent of the mercaptan groups, preferably between 3 and 30 per cent, of the original liquid polymer or polymers are reacted. The multi-functional cross-linking agent may be a polyfunctional isocyanate-terminated polymer or a polymer having oxirane ring functionality such as a polyfunctional epoxide resin. Modified liquid polymers produced by the method retain cross-linkable mercaptan terminations and when cross-linked display improved mechanical properties and are useful for example in adhesives, sealants, coatings, extrusions and mouldings.

Abstract: In a semiconductor memory system of the serial column access type, a redundant column (55) is used for replacing a defective column. Redundant data lines (SD,  SD ) are connected to the redundant column (55) through a redundant column selection gate (15). A defective address detection circuit (43) detects the address of a defective column to enable the redundant column selec­tion gate. An address counter (42) is provided for a defective address detection circuit (43). A redundant column selection circuit (25) selects the redundant column in response to a detection signal from the defec­tive address detection circuit (43). A data line switching circuit (41) switches, in redundant column select mode, the data lines connecting to a data input/output drive circuit from said regular data lines (D,  D ) to the redundant data lines (SD,  SD ). With this circuit arrangement, in a redundant column select mode, the regular data lines are separated from the data input/output drive circuit. Therefore, even if a shift register constituting a regular column selection circuit (21₁ to 21n) operates and the defective column selection gate is enabled to set up a connection of the defective column to the regular data lines, the error data from the defective column is never output. Further, the shift register is operable irrespective of the defective column detection.

Abstract: In a method of testing a spliced portion of exposed fiber portions (10₁) and (10₂) of optical fibers, the optical fibers are arranged with each other in line so that ends of the exposed fiber portions are spaced apart from each other by a predetermined distance. The ends of the exposed fiber portions are heated and melted by discharge heating. The optical fibers are then moved in the abutment or closing directions by a predetermined distance, so that the ends of the exposed fiber portions abut against each other to form a spliced portion. The minimum outer diameter value  d  of the spliced portion is measured. Ratio d/D of minimum value  d  to value D of the outer diameter of exposed fiber portion is calcu­lated. Spliced portions having splicing defects can be detected by detecting of spliced portions having ratio d/D of less than 1 (d/D < 1). That is, spliced portions having ratio d/D of less than 1 (d/D < 1) are regarded as splicing defects.

Abstract: Provided is a regeneration system of an exhaust gas filtering element for diesel particulates. The system comprises two filter elements (34a, 34b) provided in parallel with each other, a burner mechanism (1), and a four-way valve mechanism (16) for switching over an exhaust gas flow and a preheated gas flow obtained by combustion in the burner mechanism (1). The exhaust gas flow is generally passed uniformly through the two filter elements (34a, 34b) which filter off particulates. However, when regeneration is required, an elliptical vane (22) provided in a cylinder (17) of the four-way valve mechanism (16) is rotated so as to cut off the exhaust gas flow passing through one of the filter elements and cause the preheated gas to flow through this filter, whereby particulates are oxidized and incinerated. At this time, the exhaust gas flow is passed through the other filter element, without any particulates being emitted into the atmosphere. Then, the exhaust gas flow and the preheated gas flow are switched by rotating the vane (22) so that the other filter element is regenerated.
