Filed: 1990-11-20
Abstract: The specification discloses a process for the treatment of waste gas containing hydrogen chloride wherein the gas is at an elevated temperature in the range of from about 300°F to about 3000°F and is produced from the thermal decomposition of material contaminated with hazardous chlo­rinated organic compounds. The waste gas is contacted in a reaction unit (26) with an alkaline brine solution (28)under conditions such that hydrogen chloride in the waste gas reacts with the alkali to form a chloride salt and water. The heat of the gas evaporates water from the solution to maintain the salt concentration sufficiently high to cause the formation of salt crystals in the solution. The gas is conducted from the reaction unit (26) following contact with the solution under conditions such that the gas includes water evaporated from the solution. The salt crystals are removed as a solid product of the process and water and alkali are added to compensate for water vaporized from the solution and alkali consumed in the reaction. The process requires no external heat input and there is no liquid discharge.

Abstract: A jet regulator (1) for connection to sanitary fittings has a jet-splitting device (2) which is essentially formed by two perforated plates (7, 8). The perforated plates (7, 8) are connected to one another and also supported both at the outer edge and in the central region. In these connecting regions, provision is also made, at the same time, for position-fixing means, through which the perforated plates (7, 8) can be positioned in a predetermined position relative to one another in the connected position. The through-flow holes present in the perforated plates are thereby positioned in a position offset relative to one another. The connection and support of the perforated plates (7, 8) one against the other avoids vibrations and hence increased noise formation. <IMAGE>

Abstract: A method is proposed for protecting the turn-off semiconductor power devices of an invertor, whose input is connected to a DC intermediate circuit, in a three-phase bridge circuit during output short-circuits, an intermediate circuit short-circuiting device being provided at the input, and output inductors being provided at the output of the invertor. In the event of an output short-circuit, all the turn-off semiconductor power devices of one phase are switched off by turn-off signals if this phase is involved in the short-circuit, and the measured value of the load current at the instant when the short-circuit is identified is less than a first limiting value which can be predetermined. All the turn-off semiconductor power devices of a phase which is not involved with the short-circuit are switched off by turn-off signals. The turn-off semiconductor power devices of a converter phase which is involved with the short-circuit maintain the instantaneously existing switching state, by means of extinguishing switching-off signals, if the measured value of the load current of this phase exceeds the first limiting value, an extinguishing switching-off signal having precedence over a turn-off signal. The intermediate-circuit short-circuiting device is switched through when the measured value of the load current of a given converter phase exceeds a second limiting value which is above the first limiting value. <IMAGE>

Abstract: A cathode ray tube comprising a rectangular display window whose thickness increases from the centre of the display window along the long and the short axes. The thickness of the display window along the long axis is defined by: 
 
       D(x) = D₀ + △(x);           
 
 the thickness of the display window along the short axis is defined by: 
 
       D(y) = D₀ + △(y).           
 
 △(y) is larger than 1.5△(x). The display window thus formed combines a large strength with a relatively low weight. In an embodiment, the thickness of the display window along the upper and the lower side is approximately constant. This results in a further improvement of the implosion safety of the cathode ray tube. The invention is of particular importance in cathode ray tubes having a length : width ratio which is larger than 4 : 3, for example 16 : 9, and in large (>    28 inch) tubes.
