Patent DE-4126530-A1 (DE)
Title: Covering film for colouring e.g. plates in cars - has e.g. aluminium@ substrate hot pressed with e.g. reflecting film and hot stamping foil with parts of foil stripped off e.g. round edges
Inventor: MOENNING DIETMAR
IPC: B41M1/28
Filed: 1991-08-10
Abstract: The film has a coloured layer to be applied by suitable form of energy on to at least parts of the plate etc. It can be bonded on to the plate, etc. or released from it. The figure shows the cross-section of a profile consisting of a substrate (11), a reflecting layer film (16) and a hot stamping foil (23). The prod. is hot pressed so that a part of the foil (23) can be stripped off the reflecting film (16) e.g. ground the edges (33). The substrate (11) is e.g. Al sheet but alternative materials can be used (e.g. plastic film). The hot stamping foil (23) is bonded to the Al before the edges of the profile are embossed and before the (e.g.) plates are cut out of Al. This cuts out the special feed device for the hot stamping fuel which has been used hithergo. ADVANTAGE - The prod. simplifies the prodn. of e.g. markings for application to cars. In particular it simplifies the resources required to colour the plate, etc. concerned.

Filed: 1991-12-16
Abstract: In a process for improving radio cell coverage in a cellular mobile radio system, a number of neighbouring, bordering and partially mutually overlapping cells are provided, at least one fixed transmitter being arranged in the boundary region of each cell. In order to obtain the best possible radio cell coverage, the fixed transmitters of neighbouring and directly adjacent cells with the same channel group as the one to which the cell to be supplied belongs transmit to this cell. Thus a mobile station in the cell is served not only by one fixed transmitter but also by the fixed transmitters of neighbouring cells. To each fixed station are allocated several sector aerials which at least partly overlap in their transmitting range bounded by sectors and which together cover a range of at least 360 DEG .
