Patent DE-19846151-A1 (DE)
IPC: H04W28/18
Filed: 1998-10-01
Abstract: The invention relates to a method for transmitting data in two-way communication over low-voltage networks which are provided with or without coupling to a higher-order telecommunications, voice or data network. The transmission in the low-voltage network is carried out in a high frequency range greater than 148.5 kHz with a band spread of the data signals and a transmission level less than the radio and line disturbance voltage limits to be applied to the method. The signals which are distributed in the frequency and/or time range and which are provided for guaranteeing a multi-channel structure with different sequences of one or more families of numeric values are provided with a directional coding, frequency assignment or time slot assignment in order to give a receiver-specific logical direction in the low-voltage network. The binary data sequences which are channel-specifically distributed in this manner and which are characterized in a directional-specific manner are identified, regenerated, and evaluated with a new directional identification for routing the signals in the low-voltage network according to the degree of attenuation. This is carried out with the assistance of the given sequences by means of correlation, iterative or parallel disturbance signal suppression methods or by means of time/frequency transformation.

Patent DE-19850658-A1 (DE)
Inventor: KOELLIKER ROBERT
IPC: C08G81/02
Filed: 1998-11-03
Abstract: The object of the invention is a redispersible material, particularly in powder form, which comprises a polymer containing silanol groups, the latter being provided with a protective group. The redispersible material can be in the form of a redispersible powder, an aqueous dispersion or an aqueous solution. The invention also makes available a process for the preparation of a redispersible material by reacting a silanol group-containing polymer with a compound having a protective function for the silanol groups, optionally with the subsequent recovery of a redispersible, pulverulent material from the polymer provided with the protective groups. The invention also relates to the use of the redispersible material in adhesives, plastic-containing, cement-bound systems, plastic-bound, cement-free binders, wallpaper pastes, disperse dyes, glass fibre composite systems, etc. The invention is characterized in that the silanol groups in a random polymer can be temporarily protected and consequently the reactivity of these groups cannot be blocked by undesired reactions. In addition, the latently present silanols can be released in planned manner in connection with the final applications.
