Abstract: The invention relates to a process for the production of Guerbet alcohols by condensation of aliphatic alcohols in the presence of alkali metal or alkaline earth metal hydroxides as catalyst using the Guerbet reaction, in which the initial pressure in the reactor corresponds to the vapor pressure of the alcohol components used and, during the reaction, the pressure is continually reduced to the vapor pressure of the reaction mixture at the particular temperature.

Abstract: The invention is a process for applying a phosphate coating to a metal substrate in which the metal substrate is contacted with an aqueous activating bath before the phosphate coating is applied. The improved process is obtained by applying ultrasonic vibration energy to the aqueous activating bath. The ultrasonic energy can be applied to the aqueous activating bath when the aqueous activating bath is in contact with the metal substrate or when the metal substrate is not in contact with the aqueous activating bath.

Abstract: The invention relates to the use of moisture-curing PU hotmelt adhesives as molding compounds for the production of moldings, the PU hotmelt adhesives having a melt viscosity of less than 100 Pa.multidot.s at the processing temperature of 70.degree. to 190.degree. C. To produce the moldings, the molding compound is melted at temperatures of 70.degree. to 200.degree. C., the melt is injected into closed molds under an excess pressure of 1 to 50 bar, the cooled moldings are removed from the mold after a short time and are then cured with atmospheric moisture. Economic and technical advantages include distinctly lower processing pressures, expense on machinery and tooling and firm adhesion to various substrates. The moldings are heat-resistant and adhere to various substrates. They are particularly suitable for the production of electrical components.

Abstract: The invention concerns an improvement to a movable floor cleaning machine with integral clean and dirty liquid compartments which are separated from each other by a solid partition with an opening which allows liquid to pass through, and is provided with a closure member which can be opened. By virtue of the improvement, the floor cleaning machine is easy to handle and functions reliably both for recycling cleaning liquids and in normal operation. The closure member which can be opened is a valve body which is resiliently urged from one side of the partition towards the edge of the opening in the closed position. On the other side, and in the region of the opening, the partition is provided with a tubular coupling connection to one end of which a tubular coupling with an associated filter can be coupled.

The equivalent ratio of epoxy groups of said epoxidized ester to carboxyl groups of said resin acid is in the range from 1.5:1 to 0.01:1. The resin is useful as a tackifier for adhesives and has a reduced tendency to crystallize.

Abstract: Heating an aqueous mixture of a fluoroacid such as H.sub.2 TiF.sub.6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can be mixed with soluble hexavalent and/or trivalent chromium, and preferably also nitrate and chloride ions to produce a composition that provides a conversion coating with good protection against corrosion while requiring substantially less chromium than previous coatings of equal corrosion protective quality.

Abstract: A method for emptying a substantially, completely compressible container filled with a thixotropic paste, for example, a paste-form detergent. The thixotropic paste is transported by compression by a compressive force of the container toward an opening of the container and through that opening into a connected delivery tube. The compressive force is applied to a limited area of the container to deliver the thixotropic paste which is then transported by a metering pump through the delivery tube to a mixing container where it is mixed with inflowing water.
