Title: Process and device for producing diapers (nappies)
Inventor: STARY CHRISTOF
IPC: A61F13/15
Filed: 1983-12-28
Granted: 1985-07-18
Abstract: A process and a device for producing diapers (nappies) is described, and specifically that machine unit which serves to apply rubber bands in the leg region. For fastening the rubber bands to a continuous, still-uncovered film web, on which the diaper (nappy) will subsequently be built up, this film web is first laid in sections in transversely extending loops and the rubber bands are firmly adhered to the film web in the region outside the loops, bridging them. In the process the circumferential length of each loop is measured such that it corresponds at least approximately to the length of the stretched part of the rubber band. The rubber band is fastened to the film web in the tautly tensioned, but unstretched, state on both sides of the loop and then adhesively bonded to the film web with stretching also in the region lying between. Finally the absorbent pad and the cover film are applied and the web then cut up into individual diapers. The overall device consists of a total of five functional groups, namely an apparatus (10) for applying two glue tracks; an apparatus (11) for forming transverse loops; an apparatus (12) for feeding in at least two rubber bands (5; 5'); an apparatus (13) for pressing the rubber bands into the loops as well as an apparatus (14) for continuous conveying away of the film web. <IMAGE>

Title: Internal-combustion engine with a combustion space in the piston head
Inventor: SCHIER KARL
IPC: F02B23/06
Filed: 1987-12-16
Granted: 1989-03-02
Abstract: The invention relates to an internal-combustion engine with a combustion space in the piston head. Depressions extending in the direction of the fuel jets of a centrally arranged nozzle arrangement are shaped into the piston head. For a better mixing of air and fuel, a swirl is imparted to the combustion air flowing into the cylinder. As a result of this air movement, when the air flows away over the depressions breakaway eddies form on the steeply descending depression flanks, pass through the fuel jets and assist the mixture treatment. In order to reduce the kinetic energy of the circular flow as little as possible, the depression flank which is second in the direction of movement of the air flow is provided with a low ascent. <IMAGE>

Filed: 1992-05-20
Granted: 1993-12-02
Abstract: The electrostatic filtration appts. has two electrodes with a voltage between them, where at least one electrode is near a gap opening for the suspension to flow through. The narrow gap passage (5) is at an insulating layer (3) on an electrically-conductive and porous base (4).

USE/ADVANTAGE - The filter system is for the sepn. of clean water from a mixture with dispersed particles where the particles have a similar density to water and would form an abrasive layer on a membrane and have no strong natural electrical charge. The appts. gives a low pressure loss, low energy consumption and no sealing problems with little mechanical action on the material and low safety requirements. A hydrostatic pressure of only a few 10 cm liquid column is required to maintain the flow, requiring fewer moving pump parts. All the parameters can be set separately for control. There is no wear or layer formation. A continuous operation can be effected at constant parameters, without regeneration, and toxic materials can be handled in a sterile processing.

Title: Method for improving the flightpath stability of flying models
Inventor: SCHENK HELMUT
IPC: G01D1/10
Filed: 1993-09-30
Granted: 1994-12-08
Abstract: The subject matter of the invention is a method and an arrangement for improving the flightpath stability of flying models. The airspeed is measured for this purpose, and the measured value is differentiated with respect to time.

Title: Continuous belt tension control, giving constant draw tension value at edges
Inventor: SEIDEL LUTZ
IPC: B65H23/04
Filed: 1994-11-08
Granted: 1996-08-14
Abstract: To control the tension in a continuous moving belt, such as the fourdrinier or blanket in a papermaking machine, the tension is registered independently at each edge of the belt (2). These tensions are corrected independently of each other to match nominal values. Also claimed is an appts. with sensors to register the forces at both bearings (5) of one of the belt rollers (3,4), linked to independent belt draw tension control systems which act on setting drives for the tensioning roller (4).  Pref. the independent belt tension controls apply a setting in the same direction at the ends of the tensioning roller (4) to a mean value and a difference gives opposing settings at the roller (4) ends. The angular lie of the guide roller (3) is registered for comparison with an action zone between two threshold values. If the setting breaches the upper level, the independent belt tension action is interrupted, and a new action zone is set if it is below the lower level, with a narrower span. On breaching the upper level, the belt tension control is coupled and the ends of the tensioning roller (4) are set at the same time in the same direction while the angular setting of the guide roller (3) is held at a constant pitch. When the upper level is breached, an optical or acoustic alarm is triggered.
