Abstract: The baler (10) has a "vertical" bale starting chamber in which the upwardly moving rear belts (26) and the downwardly moving front belts (24) cooperate to tumble and roll incoming material into a bale. When the bale reaches full size in the expanded chamber (88), the bale is lifted to a wrapping station where it continues to spin as a binding wrapper is applied. During the lifting of the finished bale and subsequent application of the wrapper, fresh material entering the continuously moving baler is confined beneath the finished bale in a new start­ing chamber, whereupon the cycle is repeated. As the new bale grows, a discharge ramp becomes formed by certain stretches of the belts and rollers (50a, 50b) to gravitationally discharge the wrapped bale from the baler without stopping advancement of the machine.

Abstract: Process for removing phosphate from water, in which  a) at a water pH in the range of between 8 and 10 b) solid materials are added as a precipitation auxiliary, after which c) calcium phosphates are formed which can be removed from the water.   The invention has the object of creating a phosphate elimination process, by which residual phosphate concentrations of down to 10<-><3> mmol/l of P are attained while avoiding an expensive pretreatment procedure and without increasing the salts content of the water to be treated. Furthermore, the regeneration of an added detergent is to be avoided in order to minimise the amount of sludge produced and the re-use of the phosphate is to be made possible. This is achieved by arranging that there are added to the water d) alkaline earth carbonate as a precipitation auxiliary in a quantity which corresponds to a concentration in the region of at least 1 g/l of water and e) dissolved Ca(OH)2 in a quantity which adjusts the pH of the water to about 9 to 10.

Abstract: A tuned convoluted conduit assembly is especially well adapted for use in hostile environments subject to vibrations which bring on fatigue failures. To prevent the conduit from having a uniform resonance throughout its length, the convolutions have a variable height thickness form, or pitch. One way a variable wall thickness may be achieved is by forming the conduit walls by wrapping tape in successive layers (32, 34, 36) to form a multiple layered wall. The width of the tape may be such that each alternate convolution has more layers than its two different adjacent neighboring convolutions. A sleeve or stocking (100) loosely fits over the conduit and is clamped by a band (108) onto the conduit to prevent vibration of the conduit at that clamped location.
