  • Patent number: 10322635
    Abstract: A charging apparatus (1) for a vehicle that can be driven electrically has a charging cradle (4) with an access opening (8) and an electrical charging socket (5) is arranged in the charging cradle (4). A closure cover (7) is mounted pivotably in the charging cradle (4) and, in a closed position, covers the access opening (8) in the charging cradle (4) and, in an open position, opens said access opening. A sealing ring (12) which extends around the charging socket (5), and the closure cover (7) has a ring attachment (13) that makes contact with the sealing ring (12) along a ring contour of the sealing ring when the closure cover (7) is closed. Thus, the charging socket is sealed off reliably to the outside.

  • Patent number: 9941197
    Abstract: A strip-shaped substrate made from a film includes a plurality of units for producing chip carriers. Each unit has a chip island for fixing a semiconductor chip, electrodes for electrical connection of the semiconductor chip, and through-openings for structuring the unit. At least one through-opening forms an anchoring edge for a casting compound for encapsulating the semiconductor chip. A surface section of the film abutting the through-opening is chamfered to form the anchoring edge. The anchoring edge protrudes past the side of the film on which the chip island is arranged.

  • Publication number: 20130316122
    Abstract: A method for producing a laminate made up of at least two films/foils is provided. At least one first film/foil is structured and subsequently laminated to at least one second film/foil. The at least one second film/foil is punched by at least one tool in a single working step and is laminated to the structured first film/foil simultaneously. The films/foils are conveyed, at least part of the time, to the at least one tool. A laminate produced according to such a method and a device for producing a laminate using such a method are also provided. The device is suited for conveying and laminating the at least one first and second films/foils, wherein regions of the films/foils are aligned to be parallel with respect to each other. The device includes at least one tool that can be used to punch-laminate second film/foil onto the first film/foil.

  • Patent number: 4701376
    Abstract: A profiled rubber strip seal for bordering window and door openings. To simplify installation, or to promote relative movement between the strip and windowpanes, such seals are provided with overlay strips of friction-reducing material, especially synthetic materials that contain fluorine. To provide favorable conditions for satisfactory bonding between the overlay strips and the main strip, and also to make it possible to use difficult to handle materials, the elastomeric mixture of the main strip is altered by including therein silicic acid.

  • Patent number: 4489580
    Abstract: A flat workpiece such as a sheet metal workpiece is deformed by impacting e surface of the workpiece with one or several impacting tools while supporting at least a portion of the workpiece surface opposite the impacted surface. In order to control the deforming impact effect for achieving the intended shape of the workpiece, the impact strength of uniform drive impulses is modified in accordance with the desired shape. For this purpose the impacts are damped in accordance with a predetermined surface pattern of impact strengths corresponding to the desired shape. Such damping is accomplished by coating the workpiece surface prior to the impacting with a damping layer or layers having a different damping effect in different places on the surface of the workpiece in accordance with the mentioned pattern, whereby the uniform impact strength is modified in its effect in accordance with the pattern over the surface of the workpiece.
