Abstract: ABSTRACT Disclosed is a microwave filter comprising two or more rows of mutually coupled resonators operated in the dual-mode.  Additional bridge couplings link selected resonant circuits which are not directly consecutive in the transmission direction.  The resonators are arranged mechanically symmetrical relative to the center of the circuit but the equivalent circuit diagram on which the filter is based is asymmetrical in respect of the ele-ment values in such a manner that the number of additional couplings agrees with the theoretically determined, minimum number of additional couplings.     The filter is useful in satellites because of small size and weight.

Abstract: ABSTRACT OF THE DISCLOSURE      A machine for treating a pipe interior includes a carriage movable longitudinally through the pipe. A support stricture is mounted on the carriage and journalled at the top of this structure is a tubular shaft which is mounted to rotate about its own longitudinal axis with that axis being substantially aligned with the corresponding axis of the pipe.  Secured to one end of the tubular shaft is a pair of material-conveying tubular arms which are radially disposed with respect to the shaft.  A supply hose leading to a source of pressure-driven fluid material is coupled to the tubular shaft and arms, there is a deflector member which deflects a particular fluid material flowing through the shaft into the arms so as to be discharged against the pipe interior as the carriage moves through the pipe.  A diffe-rent fluid material can be applied to the pipe interior during a subsequent trip of the machine through the pipe when an inner tube is installed within the tubular shaft. This tube is connected at one end to other radially disposed arms and at the opposite end to another supply hose sub-stituted for the first supply hose.  Thus, the same machine can be assembled to perform two separate pipe treating operations such as sandblasting and painting.

Abstract: Abstract of the Disclosure An apparatus for separating particulate or lump material by size having a passage for the material, downwardly defined by a plurality of rotationally drivable material carriers which are arranged in several rows.  The carriers in one row are meshing with clearance between the carriers in the nearest adjacent rows on either side, such that together the carriers form a screen extending along the passage from an inlet for the material to be screened to an outlet for lumps of the material which are too large to fall through the screen.   The principle axes of the carrier rows are orientated in the flow direction of the material through the passage and locate the carriers in a trough-like configuration, so that the bottom of the passage and at least one of its sides are de-fined by the carrier rows.  The carriers are adapted for driving in such a direction that they impart to the material on the screen a transverse arching movement upwards and towards one or both sides of the passage, while the material simultaneously moves towards said outlet.
