Apparatus for welding together two plastic-film webs (40,41) laid around one or more articles, so as to form a heat-shrinkable envelope therearound. The apparatus includes a deck (12), on which the wrapped articles are moved to an oven (53), in which the film is heated. A first and a second welding jaw (16,26) are arranged to weld the plastic-film webs around the articles, to form a package unit (...

A gas diffusion electrode for the reduction of oxygen, which contains a hydrophobic electro-catalyst layer, is described. One side of this layer is covered with a hydrophilic layer which is composed of at least one transition metal or an oxide or mixed oxide of transition metals and can also contain a current collector in the form of a mesh. For producing the gas diffusion electrode, a hydrophobic...

A solid organic waste is fermented in water in two phases, a hydrolysis/acidification phase and a methane fermentation phase. Solid organic waste is introduced in the first phase, of which waste at least 80% of the volume has a particle size larger than x mm, x being between 0.25 and 1.5 mm dependent on the introduced solid organic waste. The waste in the first phase is continuously or periodicall...

The appts. comprises a component (3) for sampling the fed signal with a determined primary sampling frequency (f1) and converting the sample to digital form. A memory (4) stores the samples in digital form in their time sequence. A device feeds out the memory-stored samples in their time sequence at a feed-out frequency (f2) which is different from that for sampling (f1), the samples are then conv...

The support comprises two side-pieces (1) with a bearing (4) in each for a shaft (11), on which a cable drum (12) is mounted. The distance between the bearing in each side-piece and the periphery (3) varies continuously along part at least of the latter. - Each side-piece is pref. in the form of a spoked wheel with the bearing situated eccentrically.(1)

The electrode (4) supports an electrically conducting layer which is impermeable for ions. It is held in a frame which has channels for gas and electrolyte. At least one side of the separator supports the gas diffusion electrode. - The ion impermeable separate wall has an electrically conducting plastic material and an electrically active layer of conducting porous particles which are connected to...
