Abstract: 1. Dichtungs- und Abstreifer-Anordnung, 2.1 Bei Dicht- und Abstreifer-Anordnungen befinden sich in einer Nut (4) eines ersten Maschinenteiles (1) ein Dichtring (5), der auch Abstreiferfunktionen haben kann und eine Spanringanordnung (6). Die Spannringanordnung (6) befindet sich zwischen dem Dichtring (5) und dem Nutengrund und drückt den Dichtring gegen die Oberfläche eines zweiten Maschinenteiles (2), das gegenüber dem ersten Maschinenteil (1) eine zur Richtung der Nut (4) senkrechte Bewegung auszuführen vermag. Der Dichtring (5) liegt an dem zweiten Maschinenteil (2) mit einem Abstreifsteg (8) und mit einer hochdruckseitig angeordneten Kante (11) an. Es ist anzustreben, daß solche Anordnungen sowohl ihre Aufgabe als Abstreifer wie auch als Dichtung gut erfüllen, um Öl, das vorgeschaltete Hydraulikdichtungen durchdringt, mit Sicherheit an einem Austritt zu hindern. 2.2 Zum Optimieren der Eigenschaften einer Dicht- und Abstreifer-Anordnung werden die am Dichtring (5) vorhandenen Kanten (10, 11) individuell belastet, indem als Spannringanordnung (6) zwei getrennte Abschnitte eines Spannringes oder sogar zwei völlig getrennte Spannringe (61, 62) verwendet werden, welche die beiden Kanten (10, 11) des Dichtringes im wesentlichen unabhängig voneinander belasten. Dadurch lassen sich nicht nur die an den Dichtkanten wirkenden Kräfte optimal einstellen, sondern es läßt sich auch der Dichtring (5) unter vielerlei Gesichtspunkten optimal gestalten, da er nicht mehr zur Verteilung der von der Spannringanordnung ausgeübten Kräfte auf die beiden Kanten (10, 11) dient.

Abstract: A method for heating a heat-transferring flowing medium, in particular for space-heating purposes, with the aid of a boiler which is connected on the outlet side of a gasification furnace and in which no direct contact of the heat-exchange media takes place. According to the invention, the method is characterised in that, in the boiler, the burning gases from the gasification furnace are deflected by 90 degrees and the fuel particles which are carried along by the gas current and separated therefrom upon deflection are conveyed to a post-combustion. A boiler for implementation of the method, which is connected between the flame pipe (F) of a gasification furnace (0) and the take- off (7) of a chimney and has means for heating a heat-transferring flowing medium through the hot waste-gas current without direct contact of the heat-exchange media involved, is characterised by a two-part boiler housing (1). Inside the lower part (2) of the boiler housing (1), which adjoins the flame pipe (F), a combustion chamber (4) is designed. In the housing upper part (3), which is sealed towards the lower part (2), a heat exchanger (6) with vertical flow- through direction is arranged, which is surrounded by heat- transferring flowing medium and which is in flow connection at the inlet with the combustion chamber (4) of the lower part (2) and at the outlet with the chimney take-off (7). <IMAGE>

Abstract: The invention relates to a sealing device for sealing a leak inside a reactor pressure vessel in which the output of the reactor is controlled by means of control rods (2). The con­trol rods are operated by means of control rod drives which are connected to the control rod by means of rods (3) posi­tioned in tubes (4) extending through openings (5) in the reactor wall (1). Around each tube (4), on the inside of the wall (1), there is arranged a stub tube (6) which communi­cates with said opening (5) and one end of which is joined to the tube (4) by means of a weld (8). To prevent leakages from a possible crack 9 which may easily occur close to the weld (8) and may develop into a leak, an inner sealing sleeve (10) of a soft metallic material and with an outer conical surface is fitted over the tube (4) and the stub tube (6), and an outer sealing sleeve (12) of a hard metallic material and with an inner conical surface is fit­ted over the inner sealing sleeve (10). On each side of the crack (9) special contact surfaces are formed between the inner sealing sleeve (10) and the tube (4) or the CRD stub tube (6). As the outer sealing sleeve (12) is pressed in over the inner sealing sleeve (10), the latter is pressed by the conical surfaces, moving against each other, against the tube (4) and the stub tube (6), thus providing sealing at the contact surfaces.

Abstract: In the copy prevention apparatus and its method, it is discriminated whether an object is legally copied or not; a constant event is generated at or below a predetermined probability; and an abnormal operation is executed only if the two conditions of the object having been determined as an illegal copy, and the event having been generated, are satisfied. Therefore, even if the object is determined as an illegal copy, the abnormal operation is not always executed, but executed at or below a predetermined probability. Although the occurrence of the abnormal operation can be indicated to the user immediately, it is also preferable to keep the abnormal operation occurrence secret for a time and inform the user of the occurrence an appropriate time later.

Abstract: In drying apparatus for removing moisture from peat, hot gases generated by a furnace 4 are sucked through a rotary drum drier 1 by a downstream blower 16. Peat is fed into the drum drier 1 by a conveyor 3 and entrained with the gas flow for direct contact heat exchange and intensive drying action during its passage through the drier. Downstream of the drier 1, the peat and hot gases are separated by cyclone units 8 and 14. A substantial proportion of the hot gases separated from the gas and peat mixture are returned by duct 17 to the upstream end of the drying system for recycling through the drying stage. The returned gases are input to the furnace 4 by blower 6, where they are mixed with fresh combustion gas and reheated. Oxygen content in the hot gases leaving the system is monitored by sensor 58 and peat input to the drier 1 is only allowed when the oxygen content is less than 12%. Temperature within the drier is also monitored by sensor 55 and peat input only takes place when enabled by oxygen content and also when appropriate temperature conditions prevail in the drier. A water input 52 to the drying system is also enabled and disabled by the oxygen sensor 58, and water injection takes place, when enabled, if drier temperature rises to an excessive level.

Abstract: A field spraying device comprises an elongated spray beam provided with a plurality of spray nozzles (12). The field spraying device comprises an at least partially inflatable hose (18) connect­able to a compressed-air source. The hose comprises a slotted discharge opening (13) extending in the longitudinal direction of the hose. The spray nozzles (12) spray the liquid into the air flow approximately 200-300 mm below the nozzle opening which results in a uniform discharge of material. In this manner the spray beam can be situated close to the ground and the crop, respectively, with the effect that a possible wind movement is reduced. The slotted discharge opening (13) is pivotally mounted by utilizing the fact that the at least par­tially secured hose (18) is made of a resilient material. In other words the invention utilizes the feature that the resilient top portion allows a turning movement in such a manner that the dis­charge opening can be adjusted. As a result it is possible to take the velocity of the wind, the velocity of the vehicle etc. into account. Further­more it is possible to improve the utilization of the sprayed materials and to take optimum care of the crop.

Abstract: A limit switch having a fixed casing, an actuating part moveably support by the casing, and a pair of contact sets which are adapted to be activated by the movement of the actuating part, one for producing a normal switch output and the other for producing a stroke signal which serves as data for evaluating the appropriateness of the stroke of the actuating part. The other contact set may produce a signal when the actuating part has moved a certain distance more than the minimum stroke for activating the first contact set. Thus, the output from the second contact set ensures a certain stroke margin of the actuating part. Further, the second contact set may produce another stroke signal when the actuating part has been displaced close to the maximum permissible stroke of the actuating part so that an excessive stroke of the actuating part may be detected. The contact set may be purely mechanical or may also be a combination of a mechanical switch and a photoelectric switch.
