  • Patent number: 11911925
    Abstract: A method is provided for automatically adjusting a cutting gap of a slicing machine for slicing strand-shaped product calibers from a food product into slices, wherein the slicing machine includes a blade motor for driving a blade about a blade axis, wherein the blade has a peripheral cutting edge which defines a blade plane, and a cutting frame with a counter edge for cooperation with the cutting edge. Under control by a controller and without contact of the blade to the food product to be cut, the method comprises: a) moving the blade along the blade axis in an approach direction to approach the cutting frame until contact with the cutting frame, b) stopping the approach movement of the blade, and c) moving the blade back in a spacing direction by a distance corresponding to a desired size of the cutting gap, measured in a direction of the blade axis.

  • Publication number: 20240034692
    Abstract: The present invention is concerned with plasterboards including at least two layers A and B of different composition, wherein layer A includes a calcium sulfate binder and a synthetic polymer foam and the layer B includes a calcium sulfate binder and a surfactant foam and wherein the at least one layer A is a surface layer. Improved nail pull resistance can be achieved in lightweight plasterboards, if foamed synthetic polymer is present in a surface layer. The present invention further concerns a method for the production of corresponding products, an apparatus for the production of such products as well as the use of synthetic polymer foam in a surface layer to produce plasterboards with high nail pull resistance at a minimal amount of synthetic polymer.

  • Publication number: 20230002287
    Abstract: The invention concerns a method for producing gypsum boards, wherein a liquefier for the gypsum slurry is foamed with gas to provide a foam having a water content of less than 85 wt.-%, then incorporated into a gypsum/water mixture and the mixture thus obtained is applied on a two dimensional substrate. The incorporation of the liquefier in foamed form allows for a significant reduction of the amount of liquefier required to provide a desired flowability of the gypsum/water mixture, thus allowing the production of gypsum boards with similar characteristics with less liquefier. The invention further concerns gypsum board prepared using this process, apparatuses for producing gypsum boards using this process and the use of a corresponding liquefier foam to minimize the amount of liquefier required to establish a desired flowability of a gypsum/water mixture.

  • Patent number: 5727942
    Abstract: An implant arrangement for securing a denture to a jawbone includes an implant shaft which is provided at its upper end with a threaded bore whose central axis is inclined relative to the central axis of the implant shaft. The implant shaft can therefore be inserted into the jawbone such the implant shaft is inclined relative to the denture crown axis while the crown axis of the denture itself remains in the desired position. The angled implant can be inserted in a rotationally symmetrical manner without requiring additional space, even in narrow tooth gaps, by means of a special screwed-on insertion instrument.
