Patent DE-2704762-A1 (DE)
Inventor: STROBL JOERG DIPL ING
IPC: H02H3/38
Filed: 1977-02-04
Abstract: The protective switching device exhibits an alternating-current input (1) and an alternating-voltage input (2), and a process computer (11) and an analog/digital converter (8), the output of which is connected to the computer input. To avoid having to detect the instantaneous values of the alternating quantities and the associated restriction in the computer program, the alternating quantities are represented in the form of absolute amount and phase angle of the vectors of the alternating quantities. In this arrangement, the absolute amount is obtained by rectifiers (5) and can be detected in relatively long time intervals and converted into digital expressions. The phase angle is formed separately from the alternating quantity by means of additional switching means. The phase angle can be formed by various types of switching means. In one switching means (7, 14), the phase angle is identified by the times of the zero crossings which are supplied to the computer by the digital circuit (14). Instead of this switching means, the phase angle can be identified by means of a circuit (13) by an analog signal which is supplied to the computer by the analog/digital converter (8). <IMAGE>

Patent DE-2709920-A1 (DE)
Title: Self-cleaning jet e.g. for paper processing - has an elastomer shroud for brush to allow wires to pass through and be cleaned by the cladding as they retract
Inventor: VOGELMANN FRITZ
IPC: D21F1/34
Filed: 1977-03-08
Abstract: The jet tube with self-cleaning brush segments is mounted on a rail for cleaning machines in paper and cardboard mfg. The brush segments are composed of a single or multi-section base of metal or other stable material. Several layers of woven wire are incorporated in the base. The stitch size and wire thicknesses are so selected that the radial wires are long enough to range over the base to the internal dia. of the tube, while the axial wires are contained within the limits of the base. The base with the integral wire meshes is encapsulated by an elastomer, which also shrouds the projecting radial wires. For a cleaning action, a hand wheel is turned which causes the brush segments to pass over the body of the jet plate. The radial wires are forced through the flexible encapsulation and clean the jet opening. As the brush is further rotated, the radial wires retract and the elastomer encapsulation has the effect of stripping any dirt from the radial wires as they return to a position within the shrouding, and the dirt is left outside the cladding as the wires lie against the inside of the tube. The design gives a jet cleaning action which also prevents the cleaning brushes from becoming clogged with dirt removed from the jets.
