Abstract: This device (2) is used for moving a surface-cleaning apparatus (1) over the surfaces to be cleaned, with the slow advancing movements required for cleaning. The direction of rotation of the rotor (11) of the device exerts a tractor force, so that mostly braking has to be effected. The device (2) is coupled to the apparatus (1) by means of a coupling (30). Said device comprises a frame (20) having two wheels (21), a seat (29) for an operator, and a pedal drive (22-27) which acts by means of reducing gears, without free running, on at least one of the two wheels (21). The operator sitting on the seat can use the pedals to advance the surface-cleaning apparatus over the surface to be cleaned by braking or driving with the uniform, slow movements required for cleaning. The combination of surface-cleaning apparatus and the device (2) serves for derusting a ship's deck, cleaning or roughening a concrete floor, etc. <IMAGE>

Abstract: The fill according to the invention comprises a mixture of 1-30% by weight cement with 99-70% by weight of various waste material, fly-ash, de-sulphurization product or granulated blast-fur ace slag. The mixture can be used dry or mixed with water, and may also be mixed with air to form small bubbles, thereby rendering the mixture frost resistant. The fill can be used to fill different cavities and pits, such as pipe-laying and cable-laying trenches, floor cavities and holes in streets and roads, and for covering mounds of waste, rubbish dumps and for encapsulating harmful waste. 
     When filling pipe-laying and cable-laying trenches, the fill may be laid directly against the pipes without an intermediate layer of sand, and will thereby prevent water from entering into or leaking from the pipes, while at the same time holding the pipes in position and affording a stabilizing effect againt ground movement. The fill hardens to a maximum strength of 10-15 MPa after one or more years, but retains sufficient softness to enable it to be dug-up without difficulty, this hardness becoming a maximum of 10-15 MPa after one or more years.

Abstract: The mixer comprises a mixing container 1 with a vertical axis, a conical side wall and a container bottom, as well as a mixing screw which is fastened to a shaft and is driven in rotation by means of a drive arranged underneath the container bottom. The upper end of the mixing screw is rotatably mounted in a bearing of a rotatingly driven swivel arm, which for its part is rotatably driven in a central housing flange on the upper side of the mixing container by a drive arranged there. To increase the operational reliability, axial changes in length of the mixing screw shaft are taken up in a bearing arranged at the swivel arm, by the mixing screw shaft being designed as a knockout spindle. Furthermore, the swivel arm is designed as a simple arm without any built-in gear mechanism, so there are no seals, gear components or the like in the product space. <IMAGE>

Abstract: @ The novel method substantially reduces the pressure pulse, generated by a first radial motion of a body of water, by changing the radial motion into axial motion. The change from radial motion into axial motion is produced by generating a second radial motion of opposite phase within the body of water. 
     The method can be used to substantially reduce the pressure pulse, generated by the implosion of a body of water, by generating an explosion in the body of water. It can also substantially reduce the pressure pulse generated by an explosion within a body of water, by generating an implosion of the body of water. The method can further by used to generate within a body of water an impulsive acoustic signal by sequentially generating within the body of water a first explosion and a second explosion. 
     The apparatus (10) comprises a signal chamber (14) which contains a first charge (Va) of gas (G1). A normally-closed valve (12) maintains the signal chamber (14) closed and has a discharge port (16) into the water. A second chamber (14') contains a second charge (Vb) of compressed gas (G2). A second fast-acting valve (12') normally maintains the second chamber (14') closed and has an outlet (16') into the water. A controller (20, 20') explosively opens the first valve (12) so as to generate an impulsive acoustic signal (P o ) and a first bubble (1). The controller subsequently opens the second valve (12') to thereby release the second charge (Vb) from the second chamber (14') into the water, while the first bubble (1) is near its maximum volume.

Abstract: A method for forming a file of messages in a computer includes the step of first forming a first file portion as a message word table having entries corresponding to the message words, said entries ordered in the table by their frequency of occurrence in the messages. Then, a second portion as a message token string table containing a token string for each message is formed, where each token string includes several tokens, each representing a word or variable in the message. The tokens are located in the string according to the location of the corresponding words in the message. Each token has a value that represents the location of its corresponding word in the message word table. The third step includes forming a third file portion as a message look-up table that contains a unique identifier for each message and a corresponding pointer that indicates the address of a token in the token string table. In addition, the messages are retrieved by first locating the identifier in a message look-up table portion of a message file, and then retrieving a pointer that corresponds to the identifier. The pointer is used to locate the first token of a token string that represents the words and variables of a message. Each of the tokens is then used to access the message word table or is decoded to represent the variables, the words and variables are assembled in a buffer in the order of occurrence in the message token string to form an assembled or formatted message.

Abstract: Die Entfernung von Verunreinigungen aus Abgasen durch Abkühlen des Abgases mittels eines Kreislaufgases und Auskondensation der Verunreinigungen erfolgt in zwei Gruppen von umschaltbaren Wärmeaustauschern. Jede Gruppe besteht aus zwei Vorkühlern und einem Tiefkühler. Während in der einen Gruppe die Verunreinigungen auskondensiert werden, werden sie in der anderen Gruppe abgetaut. Zwecks Vereinfachung der Regelung wird in jeder Gruppe nur ein Vorkühler (1a, 1b) verwendet, der von zwei Innengasen, nämlich dem Abgas und dem Kreislaufgas, beaufschlagt wird. Für das Reinigungsverfahren sind dann nur noch zwei einfache Regelstrecken erforderlich, die leicht programmgesteuert werden können. Außerdem kann die Temperaturerhöhung des Kreislaufgases im Kreislaufgebläse (7) in der aufzutauenden Gruppe zum Anwärmen mitbenutzt werden.
