Abstract: The present invention relates to a method for transference, cooling and compression of nitrogen oxide-containing gases, In critical sections of the unit for such processes it can be formed salt deposits, but such deposits can be removed or prevented by maintaining a water vapour pressure which lies above the vapour pressure of the salt deposits at the existing temperatures. The prescribed water vapour pressure is maintained only by cooling the gas in at least one cooler and/or by cooling the gas directly by injection of liquid into the gas. The gas can be divided into several streams (2, 3,4) and cooled indirectly in two coolers (B, C) and directly in one cooler (A). The gas streams are mixed together in pipe (5) after the cooling step and transferred to compression (6). The condensate from the indirect coolers (B, C) can be utilized by the direct cooling. Salt deposits can be removed/ prevented without supply of extra energy, water vapour or liquid. The method can be adapted to existing plants without large alteration of these.

Abstract: Apparatus for collating and stacking building components, for example tiles, has pairs of conveyors with shelves for supporting edges of tiles. The tiles are fed to the shelves by a conveyor and the pairs of conveyors move upwardly in timed relation to locate tiles on the shelves. When all the shelves are full, the pairs of conveyors move downwards and apart to deposit the tiles in a stack on to a support. The timing of this avoids shock loads on the tiles. The stack of components is then banded and removed from the apparatus.

Abstract: The method allows both translatorily and/or rotationally moved and unmoved work pieces (W2) to be machined by fixed or mobile robots (R2, R3, R). During this the own movement of the work piece (W2) is taken into consideration by the robot (R2, R3, R) using programming, open-loop and closed-loop control techniques. The path accuracy and path feed rate necessary for technological applications is maintained at the moved work piece (W2). The control problem is solved by way of transformation using a chain of coordinate systems (ROS, KS1, KS2, KS3, ZAS). What is important is that the overall transformation can be planned out freely by the user using parameters (VBE1...n, ZA1...n) according to the system configuration. <IMAGE>

Abstract: A process is disclosed wherein a high-potency sweetener is treated so as to improve its handling properties, namely flowability, resistance to caking, and bulk density. According to the method, a quantity of a powdered high-potency sweetener is mixed with an agglomerating agent, such as a modified cellulose, and a limited quantity of a solvent for the agglomerating agent, such as water. The quantity of solvent is limited so as to produce a mixture which is only moist or damp. This damp mixture is characterized as being dust-free, non-flowing and crumbly. The damp mixture is then dried and the dried mixture is treated, e.g. by grinding and/or screening, to produce the desired particle size range in the agglomerated high-potency sweetener particles. These agglomerated particles comprise collections or clusters of high-intensity sweetener particles which have been bound together by the agglomerating agent.

Abstract: A robust amplifier consists of two delay lines 12 and 23 linked by a number of discrete amplifiers 13. Distortion correction is carried out by distortion feed forward. This is achieved by sampling the output of each amplifier 13 at a coupler 17 and then subtracting this sample from the input signal to later amplifiers (13) along the delay line 12 at directional coupler 19. As a result each discrete amplifier's distortion is corrected by all of the following discrete amplifiers (13) in the amplifying circuit.

Abstract: The present invention is directed to improve tank structures and the processes and apparatus for their construction. The walls of the prestressed tank are formed by inflating a membrane, applying one or more layers of rigidifying material outwardly of said membrane and then prestressing the walls by circumferentially wrapping prestressing material to minimize the tension in the rigidifying material when subject to loading. In another embodiment, wall forms are placed inwardly of said membrane to aid in the forming of the walls and circumferential prestressing. In the best mode of the invention, the walls are of reinforced plastic, fiberglass, or resin sandwich composite construction. Seismic countermeasures may also be used to protect the structure against earthquakes and other tremors, by the anchoring of the tank walls to the base and permitting the seismic forces to be shared by the seismic anchors. When a seismic disturbance occurs, the force acting on the structure can be transmitted and distributed to the footing and around the circumference of the tank.
