Title: Telecommunications systems
IPC: H04B15/00
Filed: 1979-01-11
Abstract: Methods of and apparatus for minimising the third order intermodulation noise content of an information signal which acquires this noise during transmission along an information transfer system line (2) between an input (3) and an output (4).

Title: Portable grill
IPC: F24C1/16
Filed: 1979-01-10
Abstract: A portable grill for firing with preferably solid fuel, e.g. charcoal or the like. The grill comprises a furnace, defined by a rectangular bottom wall (1), two end walls (2, 3) and two side walls (4, 5), and support means for a grill grating or the like are arranged above the furnace. Previously known grills of this kind are usually rigid and require large storage space. In some cases it is possible to dismantle at least parts of the grill, but this requires a lot of work. The object of the invention is to remove these disadvantages and provide a grill requiring very small storage space and being simple to get ready for use.
