Patent DE-3472987-D1 (DE)
Title: Improved pipe flushing device
Inventor: TASH GEORGE
IPC: E03C1/304
Filed: 1984-06-27
Granted: 1988-09-01
Abstract: The improved pipe flushing device comprises an elongated, elastomeric, hollow tubular member having a middle portion free to expand radially under water pressure. The rear Inlet end of the tubular member is fitted with a hose connector, while the narrow front outlet end of the tubular member contains a valve which opens upon expansion of the middle portion. The valve has a cage bearing a rear plate closure, and open sides and front. The rear plate is received in a transverse groove in the outlet, which groove is of a greater length than the thickness of the plate. The cage is gripped and held in a fixed position while the tubular member is in the relaxed unexpanded state. However, when the device is inflated by water pressure from a water hose connected to the inlet connector while in a water pipe, the middle portion thereof expands to meet the wall of the pipe. When the expansion is complete, the cage moves back in the outlet, the plate moving resrwardly in the groove to cause a mechanical vibration in the tubular member and water pipe. Waterthen by-passes the plate and passes through and out of the cage as a jet to break up a sewage clog. Upon expulsion of the jet, the middle portion contracts and the valve moves forward and closes, again causing sonic vibrations in the tubular member and water pipe. The expansion and contraction of the tubular member rapidly alternate to rapidly pulse water jets and vib ate the pipe to unclog the pipe.
Patent DE-3477759-D1 (DE)
Title: Winding mandrel for a wound package of flat products, especially printed products
Inventor: HONEGGER WERNER
IPC: B65H29/00
Filed: 1984-08-25
Granted: 1989-05-24
Abstract: The winding mandrel comprises a cylindrical winding drum or body which has two circumferential web members on its inner side. Each web member lies substantially in a plane which lies outside the center of gravity of the winding mandrel together with the coil or wound package. The winding mandrel bears upon two driven and tandemly arranged support wheels with one of its web members. A support roll is arranged beneath these support wheels. A lateral support surface of the web member bears against this support roll. The support wheels are constructed as friction drive wheels and, in addition to supporting the winding mandrel, serve to drive the winding mandrel. Due to the overturning or tipping moment induced by the eccentricity of the bearing points of the winding mandrel upon the support wheels in relation to the center of gravity, the winding mandrel is pressed against the support roll. This has the effect that the winding mandrel maintains the desired position during its rotation. This position is partly determined by the support roll constituting a contact roll arranged to be immovable in the direction of the longitudinal axis of the winding mandrel.

Abstract: A corrugated arrangement (15) is installed in the overdam chamber (3) of a filter tank (1) in such a way that, with the sludge liquor flap (8) being partially opened, direct outflow of the whirled-up granular filter material in the sludge liquor outflow (5) - and hence loss of filter material - is prevented. As a result of the novel arrangement (15), the washing water stream during the washing phase with air and water is quietened in the overdam chamber (3), so that the whirled-up grains can settle on the arrangement (15) and on the fixed bed (2) before the washing water passes into the sludge liquor outflow (5). In this way, it is possible partially to open the sludge liquor flap (8) even during the washing phase with air and water; this is desirable, for example in effluent filtration, in order to discharge relatively heavy suspended materials or to let the washing step proceed within a short time. <IMAGE>
