Abstract: In a process for the biological purification of waste water containing organic impurities, the waste water is mixed with sludge in a tank 1, through which flow is essentially longitudinal, in the presence of carrier particles 10 for microorganisms, and is aerated with an oxygen-containing gas through gas-introduction devices 11. Treated waste water and, where appropriate, free sludge are withdrawn from the tank 1 through a discharge line (4, 14) with retention of the carrier particles by means of retaining devices (5, 15). A substantial carrier particle distribution is maintained over the flow path of the waste water/sludge mixture. To improve the equal distribution of the carrier particles over the length of the tank, it is provided that waste water and sludge are passed in at both end zones and/or in the middle zone of the tank 1 through appropriate connections (2a, 12a, 2b); (3a, 13a, 3b), and treated waste water and, where appropriate, free sludge are discharged at least partially in the middle zone and/or at both end zones of the tank 1.

Abstract: A method for forming deep drawn highly oriented thin-walled thermoplastic articles including the steps of planarly supporting a sheet of at least partially crystalline thermoplastic polymeric material and establishing at least one differentially heated area within the sheet. The differentially heated area is to include an outer cool zone having a temperature range generally below the crystalline melt point of the thermoplastic material, a hot zone disposed within the outer zone having a temperature range generally above the crystalline melt point but below the complete melt point of the thermoplastic material, and an inner cool zone located centrally of the hot zone having a temperature range generally below the crystalline melt point of the thermoplastic material. The heated sheet is placed between a female mold unit and a forming mandrel with the inner cool zone generally axially aligned therewith. The mandrel is driven against the inner cool zone of the heated sheet and into the female mold unit so that the thermoplastic material is drawn radially inwardly toward the inner cool zone and around the mandrel forming an elongated generally cylindrical shaped preform having a central cavity. The material is longitudinally stretched a distance sufficient to cause at least a portion of the walls of the preform to undergo strain hardening while the outer cool zone maintains tension control of the sheet material throughout the forming process. The central cavity of the elongated preform is then subjected to internal fluid pressure to radially expand the preform against the interior surface of the female mold cavity. The fluid pressure is maintained for a time sufficient to allow the expanded material to cool and set.

Abstract: An improved resin sensor which senses a change in the condition of the resin by forces acting on a receptacle for the resin. The sampling resin is utilized to indicate a change of ion or equilibrium condition of the resin when employed as an indicator for resin regeneration or end of a rinse cycle in a water softening or deionization system. The sampling resin is placed in a receptacle which will confine the expansion in volume of the resin as the resin is acted upon by a sampling or indicator liquid causing the resin to exert a force on the receptacle. The receptacle for the resin allows water to freely flow in and out while entrapping the resin therein. In one embodiment, the container is composed of screened walls and the pressure sensor is a strain gauge which is attached thereto. In another embodiment, the pressure sensor is the container and in the form of a multiapertured Bourdon tube in a fluid compartment. In both embodiments, the pressure sensor will measure the change in internal pressure of the resin as it is contacted by an indicator liquid. In utilizing the resin pressure as an indication of resin regeneration or depletion, a more accurate determination can be made. Further, by employing a sensor container in a compartment water pressure is equalized and pressure differentials for the water inside and outside of the container do not have to be compensated.

Abstract: A method and an apparatus for continuously monitoring the concentration of gaseous constituents, except O2, in gas mixtures, for example in off gases from large furnaces. The method is intended to obtain the desired concentration values directly for the individual gas constituents in an undisturbed manner and with comparatively high accuracy simultaneously and separately. This is achieved by continuously measuring the concentration of the gaseous constituent using at least one electrochemical cell containing at least one solid-state subcell. The subcell contains a material which conducts oxygen ions and an electrode which contains a metal oxide and generates electrical signals which depend on the concentration of the constituent. The test signals are automatically evaluated electronically in a computer and converted into concentration values, the calculated values being compared with corresponding design values previously fed into the computer.

Abstract: The invention relates to an interferometric position measurement device in which the standard is a defraction grating (G1). Defracted component beams (+m1, -m1) are fed by means of input coupling grids (+HG1, -HG1), which have different grid constants, via optical waveguides (+LWL1, -LWL1) into a coupler (TBJ1), and are caused to interfere there. The interfering component beams are fed from the outputs of the optical waveguides (+LWL1, LWL1, -LWL1) to detectors (+D1, D1, -D1) which convert them into mutually phase-shifted electrical signals. The shift of the defraction grating (G1) is a measure of the change in position to be measured of machine components which can be displaced relative to one another.

Abstract: In high-pressure extraction, a gaseous solvent is passed under high pressure through an extractor filled with solids and thus takes up organic constituents from the solids. These are then separated off in a separator (9) and the solvent is recycled to the extractor. Especially if gas mixtures of reduced dissolving capacity are to be used as solvents in order to increase the selectivity of the constituents to be dissolved out, high gas throughputs are necessary to produce a defined quantity of product. In order to reduce the high gas throughputs, the solids are soaked before the start of the cyclic process with a gaseous solvent under high pressure without gas circulation. Both the solvent composition and the soaking conditions can differ from the extraction conditions. <IMAGE>
