Abstract: A process for manufacturing hard-soldered aluminum heat exchangers is provided. For heat exchangers which are provided with flat tubes of a narrow interior with, known soldering processing operating with a fluxing agent cannot be used or can only be used with extreme difficulty. For such flat tubes, and optionally for turbulence inserts which can be slid into such flat tubes, certain materials and coatings are provided which result in a soldered connection in the tube interior where, according to the new process, no fluxing agent is used.

Abstract: Cleaning of vacuum presses is facilitated by providing a vacuum press housing that is composed of pivotable housing elements which are in turn pivotally attached to the press frame. The horizontally hinged cylinder halves that serve as housing elements of the preliminary press are connected by way of a flange connection to a sieve plate holder which is likewise arranged on a U-shaped support of the press frame so that it is pivotally movable horizontally. Arranged displaceably at the other end of the press is a joint washer with radial and lateral sealing means. The vacuum chamber which can be raised and lowered vertically and which can be pivoted horizontally is releasably connected to the joint washer by snap closure means. Pivotal movement of the vacuum chamber is ensured by a hinge connection to the U-shaped support. The vacuum chamber is placed upon the filler opening of the lower press, and is secured by means of snap closure means.

Abstract: Alkylglucosides are prepared by acetalization of glucose with an equivalent amount or an excess of a C.sub.3 -C.sub.5 -alkanol in the presence of an acidic catalyst by a method wherein the acetalization is carried out in the presence of an alkali metal salt of a boric acid used in an amount which is equivalent to or in excess of the amount of the catalyst.The alkylglucosides obtained can be used directly, for example as solubilizers, in particular in the cosmetic sector, or can be reacted further to give higher alkylglucosides.
