    • A safety switch (1) has a support (2) of an elastomer and a through-going cavity (3). Within the cavity (3) are arranged electrical conductors (4) and (5) which in a rest condition are arranged at a distance (9) from one another. The electrical conductors (4, 5) are each formed as a strip of carbon fibers and have one broad side (6) and (7) vulcanized to the support (2) either directly or by way of a coupling layer (8). Substantially perpendicular pressure (12, 13) on the safety switch (1) leads to the deformation of the support (2) and eventually to the contact of the electrical conductors (4, 5) with each other. By this means, safety functions are controlled.

    • Hydrochloric acid having a substantially constant HCl content of 20 to 36% is produced continuously by removing hydrogen chloride from hot combustion gas. To this end, hot combustion gas containing 1 to 10% by volume of HCl and steam, this gas being obtained by the joint combustion of off-gases containing chlorinated hydrocarbons and liquid residues of chlorinated hydrocarbons, is introduced into a quenching zone, and quenched therein, down to a temperature lower than its dew point, by means of cooled hydrochloric acid containing hydrogen chloride in a concentration of 20 to 36%, which concentration corresponds to the concentration of the hydrochloric acid which is to be produced. The resulting gas-liquid mixture is separated in an absorption cooling zone into cooled hydrochloric acid and cooled combustion gas containing 0.1 to 1% by volume of HCl. The cooled hydrochloric acid is introduced into a reservoir zone capable of receiving a multiple of the quantity of hydrochloric acid produced per hour, and recycled from the said reservoir zone to the quenching zone. Additional 20 to 36% hydrochloric acid produced is taken out of the quenching cycle.
    • 通过从热燃烧气体中除去氯化氢而连续生产具有20至36%基本上恒定的HCl含量的盐酸。 为此,将含有1至10体积%的HCl和蒸汽的热燃烧气体引入淬火区域,该气体通过含氯化烃和氯化烃的液体残余物的废气的联合燃烧获得,并且被淬火 通过含有浓度为20〜36%的氯化氢的冷盐酸,降至低于露点的温度,该浓度对应于将要生产的盐酸的浓度。 将所得气液混合物在吸收冷却区中分离成冷却的盐酸,并将含有0.1至1体积%HCl的冷却的燃烧气体分离。 将冷却的盐酸引入能够接收每小时产生的多次盐酸的储存区,并从所述储存区再循环到淬火区。 另外20-30%的盐酸被从淬火循环中取出。
