  • Patent number: 9766757
    Abstract: A sensor element device for a capacitive touch switch of an operating device faces with an upper side toward the underside of a control panel of the operating device and has an illuminated display with a lighting means. Provided around the lighting means is a housing with fastening means for fastening the sensor element device to a component carrier. Provided on the outside of the housing or of the structural unit, in the region toward the upper side there is electrically conductive plastic that extends along an outer periphery of the housing. From the electrically conductive plastic there extends in the direction of the underside, toward the component carrier, a contacting means for the electrical connection thereto.

  • Publication number: 20140346022
    Abstract: An operating element has an operating element housing, on the upper side of which a protruding rib made of elastic material is arranged, the rib, or its cross section, being formed for geometrical elasticity. This can be achieved by an elastically protruding section having an extent direction outward away from the rest of the rib, essentially obliquely with respect to a plane of the upper side of the operating element.

  • Patent number: 4531908
    Abstract: A ceramic burner head in which the burner mouth is formed from a unitary porous ceramic body with parallel slits defining fuel-permeable walls between and which is bonded to upper, lower and lateral ceramic plates forming the burner body. The ceramic piece is bonded to the plates in a gas-tight manner.

  • Patent number: 4521356
    Abstract: Ceramic flatware handles of hard porcelain, aluminum oxide, silicon carbide or titanium oxide, with a center bore for receiving the tang, wherein the surface of the flatware handle is provided with a press-molded relief pattern. Flatware handles of this type are obtained by mixing the ceramic raw materials with a thermoplastic plasticizing agent and shaping them into blanks at 90.degree. to 150.degree. C. The blanks are then given their surface profile by means of a press molding device and thereafter fired. Such a process is particularly suitable for oval flatware handles and handles having a center bore which is to be equipped with ceramic screw threads.

  • Patent number: 4476151
    Abstract: A target body composed of a select target material is attached to a cooling plate for sputtering systems in such a manner that substantially no bubbles, pores or oxide layers are present in the ultimate solder joint between the surfaces joined together. A pre-soldered target body and a corresponding presoldered cooling plate are exposed, in a vacuum, to a temperature above the melting point of the solder utilized so that degasification of the liquified solder occurs and any oxide layers present are decomposed and purged from the solder. Upon cooling in vacuum, the solder resolidifies and excludes any air bubbles, pores or oxide layers. A frame body with a two-step recess, with a lower recess or opening snugly fitting about a cooling plate and an upper opening freely fitting about the solder joint can be used to practice this technique. A subsequent reflow soldering can likewise occur in vacuum at a temperature above the melting point of the solder utilized.

  • Patent number: 4341816
    Abstract: Disc- or plate-shaped targets for sputtering systems are attached to associated cooling plates by plasma-spraying a surface of such target with a compatible adhesive layer, for example composed of Ni; Ni/Cr mixtures; 80/20 Ni/Al mixtures; Ni/Al/Mo mixtures; Al/bronze mixtures; Mo; W; Al/Si mixtures, Zn, Cu, Cu/glass mixtures, etc., and then coating such adhesive layer with a solderable layer, for example composed of Cu, Cu/glass mixture or Ag, etc., and soldering such solderable layer onto the surface of a cooling plate. Preferably, the adhesive layer and the solderable layer are applied via plasma spraying.

  • Patent number: 4114464
    Abstract: An artificial hand having at least one finger and a thumb is provided with drive motor and a gear to open and close the finger and thumb. A gear wheel is secured to each joint where the finger and thumb is connected to the hand proper. A motor driven worm gear meshes with both gear wheels and reversible gears are interposed between the motor and the worm gear, whereby an axially displaceable shaft maintains the interconnection between the drive means and the worm gear.
