The present invention relates to a process for the production of hydroxylgroup-containing compounds suitable for the polyisocyanate polyaddition process from polyurea and/or polyurethane polyurea wastes by treating polyurea and/or polyurethane polyurea wastes with diols and/or polyols at temperatures from 160 to 260.degree.C, the water present in the reaction vessel preferably being removed by dis...

A recording method and apparatus and a reproducing apparatus for digital signals in which data produced by encoding video signals by, for example, the so-called MPEG system, can be directly recorded and reproduced pictures having a superior picture quality may be obtained on variable-speed reproduction. According to the recording method and apparatus, each track is divided into a first area and a ...

A disposable absorbent garment comprises a pair of elastic side sections, front and back sections, and a continuous, selectively elasticized waistband operatively joined thereto. The waistband does not substantially inhibit the elasticity of the elastic side sections, and provides the same or different elasticity to the front and back sections.

Detergent powder container/distributor device with long operating autonomy for washing machines and dishwashers, suitable for taking such detergents from a separate container or drum 20 outside the machine, to put them into a specific container 16 in such machines and then from this into the drums 13 of the same. In conformity with the invention, the container 16 is provided with revolving radial ...

A cyanoketone derivative of the following formula (1) ...(1) wherein A1 is a substituted or unsubstituted phenyl or naphthyl group, or a substituted or unsubstituted heterocyclic group; each of X1, X2, X3 and X4 is independently an oxygen or sulfur atom; each of B1, B2 and B3 is independently a hydrogen atom or a C1 to C6 alkyl group; each of Y1, Y2, Y3 and Y4 is independently a hydrogen ato...

Each of receiving spreaded signals from K users via L channels for each user is de-spreaded with a spreading code allocated to each user. Interference components among signal components in the de-spreaded signal vector Z obtained are eliminated by a de-correlation filter (33) and pilot signals are detected by a pilot detection part (34) from the interference-eliminated signal vectors for multiple ...

In a door for a vehicle, partic. of the cabriolet type, it is provided with a triangular part adjacent to the front edge of a window pane (4) raisable in the door. A flange part (8) on the triangular part is provided with a protecting sealing strip (9). By using fixed inner and outer covering components (10, 11) on the triangular part as press units, the strip can be held in position without separ...

An active adaptive control system introduces a control signal from an output transducer (14) to combine with the system input signal (6) and yield a system output signal (8). An error transducer (16) senses the system output signal and provides an error signal (44). An adaptive filter model (40) has a model input from a reference signal (42) correlated to the system input signal, and an output out...
