Abstract: A continuous grill with at least two grill rollers forming at least one grilling gap, in one aspect, includes an assembly capable of rotating relative to and projecting out of or into at least one roller. An inner rotary bearing is disposed between this roller and assembly and/or this assembly is mounted on a housing of the grill or on a carrier group mounted immovably relative to the housing. In another aspect, the grill includes at least one electrically designed and/or locally measuring thermometer disposed inside at least one roller. In a further aspect, the grill includes at least one roller coated with a non-stick coating or enameled. A method for cooking of products for grilling on a continuous grill regulates the speed of throughput of the product for grilling through the gap and/or the temperature of at least one roller as a function of certain parameters.

Abstract: The present invention relates to third generation cellular networks and, in particular, to the backbone ATM switching network between a base station and other base stations or other networks. The present invention seeks to provide a 3G cellular communications system with a reduced likelihood of failure. In accordance with a first aspect of the invention there is provided a third generation wireless communications network including a plurality of base station radio interfaces which provide cellular wireless coverage; at least one Node B and a radio network controller. The system is configured such that there are at least two signal paths between the said at least one node and the radio network controller whereby to provide an IMA protection mode or an IMA aggregation mode.

Abstract: The additive described essentially comprises a selected alkoxylated fatty amine or fatty amine derivative and a special metal salt compound, preferably a metal soap. This additive for heavy oils effects a good emulsification or dispersion of asphaltenes and other higher-molecular weight compounds and, in addition, inter alia, increased storage stability, improved pumpability due to decreased viscosity of the oil and longer service lives of the filter systems. In addition, it also effects enhanced combustion of the heavy oils. The effective amount of additive in these oils is 2 to 2000 ppm. The oils described are suitable, in particular, as furnace fuel for industrial plants and power stations and as engine fuel for marine engines.

Abstract: The invention relates to a refrigerated display case, includes a goods platform, a goods space arranged above the platform, a tub space that is arranged below the platform and is bordered by a display case tub, a blower, an evaporating apparatus and a UV sterilizing tube. The evaporating apparatus is arranged in the effective range of the UV sterilizing tube, which admits the evaporating apparatus during the defrosting, carried out with the aid of a hot-gas defrosting device.

Abstract: In a refrigerated case for food products, having a display surface and a cool-air current that circulates around the display surface, the air current flows through a filter for filtering out airborne particles, bacteria and the like. The filter covers the clear cross section of the exit opening of a circulation channel.
