Patent DE-19724905-A1 (DE)
Title: Non-destructive test for butt-joint quality between welded plastics pipes
Inventor: TOBIAS WOLFGANG
IPC: G01N25/72
Filed: 1997-06-12
Abstract: A non-destructive test for the quality of butt-welded plastics pipes involves the use of heat sensitive reversible or irreversible rapid transition materials, e.g. those which change colour on heating or have a precise melting point and form an isothermal image during the welding. The transition materials are applied either directly onto the electrical welding socket or onto an indicator carrier of film, paper or fleece which is then bonded or loosely placed around the whole socket circumference to cover the heating coils. Broad, parallel isothermal images on both sides of the joint indicate a fault-free weld quality while geometrically unequal isothermal fronts indicate a faulty weld. The breadth of the isothermal indicates the energy input.

IPC: G06F19/00
Filed: 1997-12-16
Abstract: The system has a coolant temp. detection device (20) for detecting the coolant temp. in a path towards the engine side of the thermostat (13).

Patent DE-19813887-A1 (DE)
Inventor: MOLL KLAUS-UWE
IPC: D05B23/00
Filed: 1998-03-28
Abstract: The method and devices currently used to sew textiles, causing the sewing thread to fully penetrate the material to be sewn, require mechanical elements forming the stitches that are placed on both sides of the plane of the material to be sewn. This causes manipulation, mechanical and space-related problems when sewing large materials that should not be creased. The inventive method and the new device make it possible to sew the material in a one-sided operation and require minimum space. In order to produce the seam, two or more sewing needles (1,5) alternatively penetrate the entire sewing material (3). The loop (4) formed by a sewing thread is taken up by the next penetrating needle (5) and untied. The following penetrating needle then transfers the loops of the sewing thread. The sewing needles move three-dimensionally. The method and the device are suitable for sewing large, curved material that should not be creased, for example, reinforcement fabrics for fiber reinforced materials.

Patent DE-19818738-A1 (DE)
Title: Controlled reduction of solids in the outflow from a continuous feed dispersion mixer
Inventor: STARK BERNHARD
IPC: B01F15/02
Filed: 1998-04-27
Abstract: A continuous mixing unit has a vessel (1) of diameter dB, with an agitator (5,6), liquid inlet (3) and solids feed system (4,8,10), and an extended bottom outlet (12,15) of diameter dR . To maximize the downflow velocity of the liquid, dR is significantly less than dB. To reduce the concentration of dispersed solids in the outflow stream, the charging rate of solids to the mixer from the rotary lock (9) is reduced, and the liquid downflow velocity in the mixing vessel is adjusted so that it exceeds the settling velocity of the disperse phase. The effect of this is to ensure that all liquid discharging from the vessel entrains the maximum solids, and so reduces the time taken to lower the solids content within the vessel.

Title: Method of spatial directional beam formation in direction-finding system
Inventor: SCHLIETER HEIKO
IPC: G01S3/06
Filed: 1998-05-19
Abstract: The method involves processing the signals of two groups of transducer pairs formed from identical groups, each containing at least one transducer and arranged on both sides of two mutually inclined axes, using an electronic signal processor. The method involves forming first and second groups of transducer pairs from identical groups, each containing at least one transducer and arranged on both sides of two mutually inclined axes. First and second amplitude summation signals are computed from the amplitudes of the complex output signals of the first and second groups using an electronic signal processor. First and second difference amplitude signals are computed from the complex output signals of the two groups. Resultant output signals for two main beam formation planes are computed and combined by multiplication to form a three-dimensional focused directional beam.
