Abstract: A method and a device for winding electric coils, especially for winding coils with induction-free winding, are proposed, in which method at least two wires (60', 61') drawn off supply coils (60, 61) are guided individually during the winding operation by means of a wire guiding device (40), starting from the individual supply coil to the region of the coil former (55) which is stationary during the winding operation. The device (100) essentially comprises the wire guiding device (40) arranged on a support part (35) and which has a head piece (45) which is mounted so as to be rotatable about its own axis (F) and is in operative connection with an electromotor drive (30), in which head piece a core piece (46) arranged eccentrically with respect to the axis (F) of the head piece (45) is arranged. The core piece (46) has two tubes (47, 48) arranged at a distance from one another for the wires (60', 61'), which tubes are provided at the end with sloping outflow parts (47", 48") arranged in opposition to one another. The support part (35) having the wire guiding device (40) is adjustable by means of a cross-table coordinate system (20) on the one hand along two of the coordinates (X, Y) oriented at right angles to one another in the plane, and on the other hand in vertical direction (Z, Z') in relation to the top table element (15) of the coordinate system. <IMAGE>

Abstract: A method of producing a silicon nitride sintered body which comprises using an amorphous Si₃N₄ powder having a mean particle size of 5 to 50 nm, a nitrogen content of 30 to 39 wt. %, an oxygen content of 1 to 10 wt. %, the sum of the nitrogen content and the oxygen content of 38 to 42 wt. % and an unavoidable impurities content of less than 500 ppm as the raw material to form a molded body, sealing the molded body in a capsule and treating it with HIP in the range of 1000 to 18000°C and 1000 to 2000 atm until the relative density becomes 3.1 to 3.4 g/cm³. In the producing method of the invention, active surface energy of silicon nitride powder is utilzed as the driving force for sintering due to making super fine powder. The super fine powder improves sintering ability by uniform mixing. The sintering ability is further improved by substituting a suitable amount of the nitrogen in the silicon nitride with oxygen. By the above means, the sintering strength can be secured under not severe sintering conditions. As a result, sintering aid can be omitted.

Abstract: In order to compensate for errors in the positioning of a tool by a servo motor (4) resulting from mechanical inaccuracies in the machine tool slides (2) and drive (3), an analogue error compensation signal (12) is generated by a compensation unit (1) in which is stored calibration data relating to the components of the positioning error. The error compensation signal (12) is summed by a summation unit (14) with the uncompensated analogue position error signal (7) generated at the output of a CNC controller (5), and the resulting signal (15), as modified by the usual velocity feedback signal 10′ from the servo motor (4), is used to drive the servo motor (4). The resolution of the error compensation signal (12) is arranged to be greater than that of the position error signal (7), which is generally limited by the number of bits of the digital to analogue converter in the output stage of the controller (5). As the demand position is closely approached the servo (4) is driven substantially by the error compensation signal (12).

Abstract: Pure gaseous hydrogen and liquid carbon dioxide are produced by reacting hydrocarbon in a stream reformer 14 and a shift convertor 28 and passing the effluent from the latter through a four bed hydrogen PSA separator unit 38 and then a carbon dioxide PSA separator unit 48. The carbon dioxide PSA unit 48 produces a hydrogen-rich stream which is recycled to the feed to the steam reformer 14, a carbon dioxide-rich recycle stream which is recycled to the feed to the carbon dioxide PSA unit 48 and a carbon dioxide-rich product stream which is compressed in compressors 62 and 64, partially condensed in heat exchanger 68 and separated in a distillation column 70 to produce a pure liquid CO₂ product. A waste stream from the column 70 is recycled to the feed to the carbon dioxide PSA unit 48. A portion of the carbon dioxide-rich product stream is withdrawn intermediate the compressors 62 and 64 such that its pressure is higher than the operating pressure of the carbon dioxide PSA unit 48 and returned thereto as a cocurrent purge preceding bed regeneration to obtain the carbon dioxide-rich product stream.

Abstract: Baling machines with a variable volume baling chamber usu­ally produce dense bales of crop which is the normal re­quirement. It is sometimes desirable, due to wet operating conditions, for the bale to have a "soft" core which can more easily have its moisture reduced. The density of a bale depends in conventional machines on the resistance offered by the rods of hydraulic tension cylinders against expansion of the chamber as the bale grows in size. 
     In the present invention pressure in the rod ends of these cylinders (80) is controlled by a valve (96) movable be­tween a position allowing one-way flow from a source of hydraulic pressure to the rod ends and a position allowing free flow. 
     In the one-way position of the valve (96) the ends of the cylinders (80) are connected through a high pressure re­lief valve (104), whereas in the free flow position this relief valve (104) is by-passed and the ends are connected via a low pressure relief valve (102). 
     The free flow position affords the production of a soft core, and thereafter the valve is moved to the one-way po­sition to give the bale a dense outer portion.

Abstract: The invention relates to a device or a ventilator for controlling the flow rate of a flowing medium by means of a valve (1) whose valve opening can be varied via closing means, and a first control loop 20 having negative feedback. The control variable produced by the control loop controls the closing means in such a manner that the difference between the desired and actual value for the flow rate tends to zero. In order to be able to achieve rapid changes in the flow rate with a high control accuracy, at least one second control loop (30) is provided, to which the control variable of the first control loop (20) is supplied as a desired value. The actual value for the second control loop may be, for example, the measured position of the closing means. The bandwidth and gain can be optimised for each control loop (20, 30). The power consumption can be reduced, and battery operation simplified, by current recovery.

Abstract: Methods of forming layers of material upon or below the earth's surface and above the water table to prevent or effectively inhibit the flow of groundwaters through such laters of initially unconsolidated materials. Chemical components are added to materials such as incinerator ash or other waste materials deposited in a landfill operation to create alkaline conditions which, when contacted by water, induce precipitation of calcite in sufficient quantities to produce a cementing action which retards leachate formation. In another aspect, a site is prepared for use as a landfill with an essentially hydraulically sealed sub-base by choosing a site with alkaline soils or carbonate bedrock and adding appropriate chemical components to cause calcite to precipitate when contacted by water, which may be applied directly or by naturally occurring precipitation. In yet another aspect, low level radioactive or other potentially hazardous wastes are disposed of by placing containers of such waste in underground chambers and filling the balance of the chambers with chemical components to create an alkaline buffer zone in which calcite is precipitated to provide a cementing action and retard incursion of groundwaters through the buffer zone.
