Abstract: Preparation of derivatives of benzene containing CF.sub.3 groups from the corresponding compounds containing CCl.sub.3 groups (e.g. trichloromethyl benzene) is carried out continuously with excellent yield rates by reaction with liquid hydrogen fluoride in an autoclave above 80.degree.C, (which latter exceeds the stoichiometric proportion by at least 25 mole %). The reactants are fed continuously into the autoclave. The reaction mixture preferably becomes pressurized to at least 20 atmospheres and homogeneous after having reached a certain filling level. The reaction mixture is thereafter withdrawn proportionally to its feeding-in rate. The mixture may be conveyed through one or several additional autoclaves with the final withdrawal of the reaction mixture being out from the terminal autoclave of this cascade. The fluorination products are well known starting and inermediate products for the preparation of dyestuffs and pesticidal compositions.

Abstract: A hygienic douche apparatus including a nozzle for insertion into a vaginal passage and a cooperating fluid holding container are provided. The container includes a separate compartment therein to hold a compound which is soluble in a fluid such as water and, when dissolved, forms a hygienic douching fluid. The compound includes an ingredient which reacts with water to evolve a gas to pressurize the container and dispel the hygienic douching fluid through the nozzle. The compartment includes means operable from outside the container to initiate contact between the liquid and the compound. The apparatus is also adaptable to be used with an enema-type nozzle to provide a convenient readily dispensible enema and with a bidet nozzle to provide a convenient bidet apparatus.

Abstract: In a transport container for dangerous liquids, a protective shell is provided for the charging and emptying fittings mounted on the container. The shell consists of an upwardly opening shell structure mounted on the container and having a central portion which extends into the container, with a pair of exposed end portions that extend outwardly from the container; at least one of the exposed end portions is opened to allow drainage of fluid from the shell. The charging and emptying fittings, and other control devices, are positioned in the shell where they are protected against corrosion and breakage, and yet are readily accessible for operation.
