  • Patent number: 9066577
    Abstract: The invention relates to an injection molded part with a basic body 1 injection-molded from plastic, on the surface 2 of which a decoration 4 is two-dimensionally applied and is covered by an encapsulation 7 of plastic by a second injection-molding operation. The basic body 1 consists of a transparent plastic and the decoration 4 is applied with its visible side 5 to the surface 2 of the basic body 1.

  • Patent number: 5802932
    Abstract: A cutter which performs the function of either the outer or the inner cutter in a cutting device comprised of outer and inner cutters of an electric shaving apparatus or an electric beard trimmer. The cutter includes in its cutting area configured as a plane sliding surface a plurality of teeth extending from a comb strip with slots therebetween and with cutting edges formed on the tooth edges. Arranged on the cutter are one or several wall portions angled relative to the cutting area. The cutting area of the cutter includes a blade made of hardened sheet steel, with the teeth of the blade being produced by etching. The wall portions of the cutter are formed by welding one or several formed sheet metal sections to the blade. The weldment is effected such that the resulting rise in temperature of the blade is so low that the hardened sheet metal material is neither adversely affected by deformations nor exposed to significant losses in respect of hardness and wear resistance.

  • Patent number: 4552832
    Abstract: A method for producing a shear element having protrusions on the skin contacting surface thereof, including the steps of coating an electrically conductive surface with a photoresist, exposing the photoresist to a hold pattern and developing the photoresist to produce a grid pattern wherein the electrically conducting surface is exposed, the grid pattern defining hole areas wherein the electrically conductive surface is covered by islands of photoresist of a predetermined thickness, introducing irregularities into the surface elevation of the exposed grid, the surface irregularities being of lesser dimension of the thickness of the photoresist islands, depositing an intermediate foil onto the exposed grid overlying the introduced surface irregularities, the intermediate foil being of sufficient thickness to extend above the photoresist islands when deposited, depositing a shear foil overlying the intermediate foil, and removing the shear foil from the intermediate foil, thus producing a shear foil having prot
