Patent DE-3902781-A1 (DE)
Title: Waveguide frequency filter
Inventor: ILSANKER ANTON
IPC: H01P1/213
Filed: 1989-01-31
Abstract: Conventional waveguide frequency filters like a diplexer for separating two frequency bands of different frequency require a relatively large physical space. In order to create a frequency filter which occupies a small physical space, the invention provides that the second waveguide section (2) and third waveguide section (3), which each transmit a first frequency band and a second frequency band, which differs from the first, of the entire range of frequencies transported in the first waveguide section (1), are located in a fork-shaped extension of the first waveguide section (1), and that an output device having a fork-shaped waveguide distributor piece (7), and filter devices (9) having an output characteristic which acts alternately with respect to the two waveguide sections are provided. The waveguide frequency filter is suitable especially for separating very short electromagnetic waves, primarily for the field of satellite reception. <IMAGE>

Title: Biological water cleaning plant basin - has inserts in the base of coarse grain material to increase the cleaning action and prevent overflow
IPC: C02F3/32
Filed: 1990-12-19
Abstract: The waste water cleansing basin has inserts of a coarse grained material placed in the bonded base. The inserts have a depth of up to 85% of the thickness of the base. A longitudinal drainage effect in the lower section of the base body is prevented. Pref. the inserts of coarse grain material are at right angles to the flow direction of the water, across the whole cross section of the basin, and at least one layer in the centre of the basin is in the bonding base. Each pair of adjacent inserts are linked at their bases by a further coarse grain insert, as a horizontal connection, to give a paired action, without any links between pairs. The inserts are placed at increasing intervals in the flow direction of the water, according to an arithmetical series. One insert of coarse grain material is directly at the side of the water entry into the basin. The inserts can be pitched at an angle from the vertical, against the water flow path. The inserts can also be parallel to the water flow line, starting at the side of the water entry to the basin and ending in front of the outlet at a gap which is one-quarter of the basin length. The coarse grain inserts can be round, circular, arced, triangular or trapezoid, in a concentric, radial or ray formation. They are positioned so that the side surfaces of the inserts are fully covered by the bonded base. The coarse grain inserts account for up to 10% of the base volume in the plant basin. The coarse grain material for the inserts is derived from, household, industrial or commercial waste, or agricultural waste. The waste material can be plastics waste, worn vehicle tyres or shrubbery. ADVANTAGE - The system increases the biochemical-chemical cleaning action on the water, improve the water flow path, and prevents overflow into the surrounding ground.
