Abstract: A method for maintaining a stable liquid level in a pressurized chamber is described. According to this method a liquid to be treated is heated by direct contact with steam with the consequential condensate being mixed with the treated liquid and removed from said chamber. The following steps are provided: establishing a desired flow rate of liquid to be treated into said chamber, supplying saturated steam to said chamber to heat said liquid by contact heating to condense the steam, collecting the treated liquid along with the condensed water from the steam to maintain a predetermined liquid level in said chamber, varying the rate of steam supply and pressure to maintain the predetermined treatment temperature of the liquid as it is removed from the chamber, and selecting and using for each liquid to be treated a fixed flow area device (276) to control the rate of removal of said treated liquid from said chamber to maintain said predetermined liquid level irrespective of variation of control and said steam supply. An advantageous application field of this method is a process for heating fluids to a relatively high temperature, such as sterilization of UHT temperature, in which the liquid is heated by direct contact with steam while it is held in the form of a very thin, free-falling or a continuous falling stream.

Abstract: The known nuclear hydroxylation of substituted phenols or phenol ethers with organic solutions of hydrogen peroxide in the presence of a catalyst is carried out in improved manner by employing both (1) a special, practically water free solution of hydrogen peroxide in an organic solvent which forms an azeotrope with water, which azeotrope boils below the boiling point of hydrogen peroxide, and (2) sulfur dioxide as a catalyst. Through this, the nuclear hydroxylation is substantially simpler than previously; difficult separations, e.g., from water-phenol, or the separation and recovery of the catalyst are eliminated. Besides, the yields are increased.

Abstract: A process for producing corrosion inhibiting particles comprising binding corrosion inhibiting anions to particles of an inorganic oxide by ion-exchange to form anion-exchanged particles, the anions of which are releasible by further ion-exchange in which the inorganic oxide particles having surface hydroxyl groups are first contacted with an acidic solution containing labile anions at a pH sufficiency below 7 for the protons of the hydroxyl groups to be replaced by the labile anions and thereafter contacting the particles of the labile anion-exchanged inorganic oxide with a solution containing the required corrosion inhibiting anions so that the labile anions are replaced by the corrosion inhibiting anions. The labile anions are anions of water soluble, acid compounds which have a lower affinity for the oxide surface than the required corrosion inhibiting anions and which form a soluble salt with the cation of the compound providing the corrosion inhibiting anions. The process facilitates the use of corrosion inhibiting anions which are sensitive to low pH in the preparation of corrosion inhibiting particles. In particular the process is useful for producing molybdate exchange inorganic oxide particles.

Abstract: To produce drilled holes with an undercut, drills are known which have lateral cutting edges projecting at the drill head. The lateral cutting edges are formed from carbide drill tips. When producing the drilled hole, the drill can wander laterally as a result of poor centring, which makes it more difficult to insert an expanding plug. The drill has a drill head which is enlarged in diameter relative to the shank and on which the drill tips with their lateral cutting edges only project slightly. The drill head brings about a good centring effect during the drilling operation, as a result of which straight drilled holes can be produced. <IMAGE>
