Abstract: A rotary biological contactor (20) ("RBC") comprises blocks (22) of plastic media in rings (24), five blocks per ring, mounted on a metal framework (26) on a horizontal rotary shaft (28), with the rings (24) axially spaced apart. Each block (22) is a stack of sheets (30, 32, 34) of plastic media, defining part-annular channels (36) between them, concentric with the shaft ((28). The sheets (30, 32, 34) have protruberances (52, 54) to space the sheets apart in each stack. Each stack of sheets (30, 32, 34) is placed between two support plates (37) and held together by two plastic through-members (38, 40). The framework (26) comprises axially-spaced-apart frames (90) between the rings (24), with sub-frames (92) having radial arms (94) and outer and inner connecting members (96, 98) forming a trapezium and two metal support members (102) extending through holes (80) in each stack on a common radius. The protruberances (52,54) deflect fluid being treated radially inwardly and/or outwardly from channel-to-channel (36) as the RBC is rotated.

Abstract: In a process and a device, a cellulose suspension of thin consistency, the consistency and flow rate of which is known, is conducted to the suction side of a main pump (4), to the pressure side of which there are coupled in sequence a first multi-hydrocyclone unit (6) for cleaning out heavy impurities, a second multi-hydrocyclone unit (7) for cleaning out light impurities, and a headbox (8) for a wet machine or paper machine (9). This provides, on one hand, cleaning and pulp or paper production uninterrupted by intermediate storage, and on the other hand a thickening of the pulp in the second multi-hydrocyclone unit from a suitable consistency for cleaning to a thicker consistency suitable for spreading on a wire or the like.

Date Mar. 8, 1990.In a method of treating wood-fibre pulp, particularly pulp which contains recycled paper, the pulp is dewatered and then heated by means of superheated steam under pressure prior to being passed to a disperser (10), in which the pulp is finely divided. The pulp is passed from the dispenser to a plug-outfeed screw (20) withouth separate departure of steam from the system. One end of the screw is closed by means of a valve device (21), so that the pulp carried by the screw will be compated to form a plug which seals the system. The valve device (21) located at one end of the screw (20) is constructed to open when the pressure exerted thereon by the plug exceeds a pre-determined value. The invention also relates to a disperser (10) having a substantially rectangular outlet which is connected to a plug-screw (20) of the above kind.

Abstract: A program-controlled communication system consists of, among other things, a digital computing system with a computer core (processor) managed by a multi-tasking operating system and a system memory in which a multiplicity of program modules (PM 2) is stored. Each of the program modules is used for implementing a particular function of the communication system. A function can only be executed by the relevant program module being processed by the computer core. Since, as a rule, several functions are ready to be executed, the program modules ready for execution are noted in a process list (PL) from which the operating system (Bs) in each case selects the program module having the highest priority (Pr) and allocates it to the computer core for execution. To be able to prevent a prolonged displacement of program modules with low priority, the program modules are combined in groups (so-called program module function classes (Kl)) which are successively in each case assessed to be current for a certain time in periodic sequence, the operating system, when selecting from the process list, in each case only taking into consideration those program modules which belong to the program module function class which is current in each case. <IMAGE>

Abstract: The present invention relates to a process for cleaning soil wherein the soil to be cleaned is brought into a layer with a thickness of 1 to 2 m on an impermeable bottom, liquid is spread over the soil and liquid is withdrawn from the bottom side of the soil depot by means of a drainage system wherein the liquid withdrawn from the soil is subjected to a biological and/or physical-chemical purification and the excess of liquid, if any, is thus discarded and the remainder is supplied to the soil again, if desired after the addition of nutrients and/or micro-organisms and/or an extraction agent or detergent. If desired, the soil can be worked periodically. Especially in case of volatile components, air is withdrawn from the soil to remove the volatiles. Air injection is an expedient means to provide additional oxygen in the soil.

Abstract: The purpose of the façade plate, which is intended, in particular, for panelling the façade between window openings in a building fitted with transparent glass panes, for example insulating glass panes, is to produce a glass façade which is visually uniform in outward appearance. The façade panel has a transparent glass backing at the back of which there is a metal oxide coating to match the outer appearance of the façade panel in reflection and hue to that of the glass panes and an essentially optically dense outer layer applied to this coating on the side remote from the glass backing. The panel is characterised in that an inner layer (12) formed as a light-transparent metal or metal-alloy layer is applied to the glass backing (10) and its thickness is such that it reduces the light transparency of the glass backing (10) coated with it by 30 % to 85 % compared with the uncoated glass backing (10), in that the metal oxide layer (14) adjacent to the inner layer (12) is formed as a dielectric layer composed of at least one metal oxide and has an optical thickness in the range from 60 nm to 100 nm, in that the outer layer (10) is formed as such a metal or metal-alloy layer, in that the light transparency of the finally coated glass backing (10) is < 5 % and its light reflection in the outer appearance is in the range from 8 to 25 %, and in that the metals used for the inner layer (12) and the outer layer (10) are chosen in such a way that the ratio n/k of the real part n and the imaginary part k of the complex refractive index of these layers is between 0.2 and 5. The invention also relates to its use. <IMAGE>

Abstract: In multimeters having a plurality of input connections there is a danger of the measuring conductors being incorrectly connected in such a manner that the setting of the measurement range switch does not correspond to the input connections to which contact is made. In order to avoid damage which may be caused by making an incorrect contact to the input connections, an electrically and/or mechanically acting disabling device is coupled to the measurement range switch for permitting a disabling of particular input connections. The disabling is carried out in such a manner that contact can always only be made to that input connection for receiving a test signal through the measuring conductors, to which a measurable variable is assigned that corresponds to the measurable variable set with the measurement range switch.

Abstract: The detonating cord is used, for example, in oil exploration at great depths, where it must withstand high temperatures and pressures. The sheathing (11) is produced from a shrinkable hose (12) which is thermally shrunk onto the raw cord (10) containing explosive. The hose (12) consists preferably of radiation-crosslinked polyethylene. The use of a shrink hose does away with the long preparation and curing times of plastic sheathing. The process temperatures required for shrinking are acceptable with regard to safety from ignition of the explosive. The process allows in particular detonating cords for high pressures and high ambient temperatures to be produced without any problems. <IMAGE>

Abstract: When the seats of passenger transport vehicles are arranged in rows, the space between the backrest and rearside of the backrest of the seat in front constitutes the survival space for the passengers in the event of an accident. Therefore, the backrests should not be too greatly deformed by the impacting passengers in the event of an accident so that this survival space is not excessively reduced. According to the invention, this is achieved, and nevertheless the peak impact energy resulting from deformation is absorbed, by virtue of an extension of the backrest frame which becomes embedded in an angled portion. <IMAGE>
