  • Patent number: 4713440
    Abstract: A processor for the preparation of urea condensates and the preparation of heat-curable surface coatings.To prepare these urea condensates, primary di- and/or polyamine is reacted with urea, a secondary monoamine and a polyalcohol which contains certain groups at elevated temperatures and in the presence or absence of a catalyst, and the ammonia formed is separated off.These urea condensates are suitable as binder components in heat-curable surface coatings, in particular for heat-curable cathodic electrocoating finishes.

  • Patent number: 4712148
    Abstract: In a tape cassette, particularly a video tape cassette, equalization of electrostatic charges between the two faces of the tape is effected by a connector element or connector elements electrically connecting at least one of two electrically conducting guide elements contacting the front of the tape and provided on the two sides, respectively, of the cassette with at least the associated one of two electrically conducting tape deflecting elements provided in the two respective front corners of the tape cassette. In this manner sticking of the tape to the deflecting elements due to electrostatic attraction therebetween and also the build-up of electrostatic charges along the tape path parallel to the front of the cassette housing due to the transporting of such charges from the deflecting elements as a result of the tape travel, are counteracted.

  • Patent number: 4709099
    Abstract: Polyethers having molecular weights of about 1000 to about 75,000 modified with alpha-olefin oxides having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in aqueous systems. About 1 to about 20 percent by weight based upon the weight of the polyether is required, the proportion of alpha-olefin oxide modifier varying inversely with the molecular weight of the polyether. Modified polyethers, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The modified polyether thickening agents of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.

  • Patent number: 4709288
    Abstract: An adjusting means for tape guide elements or magnetic heads effects adjustment exclusively in a plane at right angles to a reference surface. A fine adjustment mechanism, in particular a micrometer screw device, provides high accuracy of adjustment over a sufficiently wide range. The adjusting means can be used in any kind of magnetic tape cassette. Advantageous embodiments of such magnetic tape cassettes also form part of the present invention. By using the novel adjusting means, azimuth and skew losses can be compensated for in a simple manner.
