The touch-sensitive arrangement forms part of the housing containing the display device, and the housing can be displaced in relation to the display device, by way of the touch-sensitive arrangement.

A lamp reflector having a reflector body enclosing an inner space, whose peripheral wall forms a lateral surface of a geometrical body with a longitudinal axis. The reflector body has a light exit opening and a base section opposite thereto. The peripheral wall is formed by a wall section forming the base section, and, extending therefrom in the direction of the light exit opening, by circumferential adjacent segments that are separated by slots. The segments are secured to the perimeter of the reflector body via a holding ring that encloses it. On their free ends, the segments have outward angled flange sections that jointly form a circumferential flange rim. In its mounting position, the holding ring is adjacent to the flange rim and is at least force-fitted to the flange rim.

A dispensing opening is provided in the closing portion of the insert, wherein a cover is attached to the insert for closing the dispensing opening.

Apparatus for bonding at least two plies of a fibrous web, includes: a first roller having an outer periphery, at least one embossing protuberance provided on the outer periphery; and a second roller having an outer periphery and being elastic at least in a radial direction, the second roller including at least an inner layer and an outer layer that is harder than the inner layer, the second roller together with the first roller forming a nip through which the two plies are to be fed, wherein an embossing element is located on top of at least one of the embossing protuberance(s), an embossing area of each embossing element being smaller than an embossing area of the corresponding embossing protuberance(s) so that the two plies are bonded at discrete locations corresponding to the first and second embossing elements. Multi-ply product including the bonded plies and corresponding method are also described.

The invention relates to a method of manufacturing cross-wound bobbins. In the method, the wiring device (12) performs a first wiring run (41, 51) with a first run length (h1) and a second wiring run (44, 54) with a different second run length (h2) . According to the invention, the length (h1, h2) of the inversion region (41.1, 44.1, 51.1, 54.1, 41.2, 44.2, 51.2, 54.2) of said first and second wiring runs (41, 51, 44, 54) Can be adjusted relative to each other so that in an intermediate region (45, 55) between inversion regions (41.1, 44.1, 51.1, 54.1, 41.2, 44.2, 51.2, 54.2) said first and second wiring runs (41 , 51, 44, 54) have the same wiring speed, and the wiring frequencies of the first and second wiring runs (41, 51, 44, 54) are consistent.

Polymer composition comprising a propylene copolymer and a styrenic based elastomer.

A nail screw, in particular for connecting facade boards or terrace planks made of wood, especially real wood, has a shaft, a conical tip formed at the front end region of the shaft and a head formed at the rear end region of the shaft. A thread has a forward facing insertion flank and a rearward facing grip flank between the conical tip and the head. The thread is a double thread, wherein a grip flank angle (α) measured between the grip flank and a plane perpendicular to the longitudinal axis of the nail screw is between 25 and 35 degrees, more preferably between 28 and 32 degrees, most preferably 30 degrees. The conical tip has a tip angle (ε) between 80 and 120 degrees, more preferably between 90 and 110 degrees, most preferably of 80, 90 or 100 degrees.

The invention relates to a multi-layer body (1) comprising a first layer (13) having a multiplicity of first zones (21), which are respectively separated from one another by one or a plurality of transparent second zones (22). The multi-layer body has a second layer (14) composed of a transparent material, said second layer being arranged below the first layer (13), and a reflection layer (15) arranged below the second layer (14). The second layer (14) has a multiplicity of third zones (23), in each of which a microstructure (17) is impressed into the interface—facing away from the first layer—between the second layer (14) and the reflection layer, which is covered with the reflection layer (15). Each of the microstructures (17) is configured such that it reflects back and/or diffracts back light incident perpendicularly with respect to the plane spanned by the first layer from the direction of the first layer in the region of the respective third zone (23) onto a region of the first layer whose area is smaller than the area of the respective third zone (23) by at least a factor of 10. The microstructures (17) are arranged in accordance with a microstructure grid having a distance between adjacent microstructures in a second spatial direction of less than 300 μm.

A lighting device and a method of operating a lighting device are described. A plurality of LED elements (12) are electrically connected to form at least two groups (1, 2, 3). Each group of LED elements comprises at least one string (30) of at least two LED elements (12) electrically connected in series. A step driver circuit (14) supplies electrical power to the LED elements (12). The step driver circuit (14) operates the groups (1, 2, 3) of LED elements (12) from a periodically varying supply voltage V by activating the groups selectively depending on a momentary voltage value of the supply voltage V. The LED elements (12) are arranged on a carrier (26) forming an arrangement pattern. In order to achieve an improved optical appearance in particular in a dimmed state, the LED elements (12) of at least one of the groups (1, 2, 3) are located on the carrier (26) so as to be evenly distributed over the arrangement pattern.
