Abstract: A method for enlarging the interference-free dynamic range of non-linear signal-processing components in receiver systems, in the conversion of input frequencies fin into output frequencies fout. According to the invention, at least one linear combination of at least one input frequency fin,t, fin,b and a fixed, predetermined oscillator fLOn of the components is calculated from the output signal of the component, for at least one output frequency fout,s, fout1,s, fouts,2, which combination is compared with any desired output frequency fout,t of the component, whereby the output frequency fout,s, fout1,s, fouts,2 is then recognized as a spur and eliminated from the output signal of the component, if the calculated linear combination corresponds to any desired output frequency fout,t of the component, within a frequency and power range that can be predetermined.

Abstract: A device for generating tunable light pulses has a non-linear optical fiber. The optical spectrum of femtosecond light pulses can be modified by this optical fiber, taking advantage of solitonic effects. In order to make available such a device, which makes it possible to vary the pulse energy and the wavelength of the light pulses independently of one another, an optical compressor precedes the non-linear optical fiber.

Abstract: A device for finishing woven denim textiles is described which, proceeding from unfinished goods, is supposed to be brought to predetermined reference values for finished width, skew and woof thread density. The device is supposed to be designed for continuous operation for regulating all three reference values. According to the invention, a stretching device, such as a rack or a loop dryer, and a shrinkage system for continuous throughput of the woven denim textile, are arranged one after the other. Directly behind the stretching device, particularly, at the same time, behind the shrinkage system, a single measuring device, preferably as an optical detector having a digital camera, is provided. The measuring device is designed, at the same time, for detecting the actual values of finished width, skew and woof thread density, and is supposed to be connected, in control circuits, with devices for achieving the reference values.

Abstract: The invention relates to a piston (1), which is comprised of an approximately circular cylindrical upper area (5) and of a lower area (6), having two hubs (7), which are set back toward the piston central axis (8) so that, in the upper area (5), recesses (12, 12?) can be made, which are open toward the lower area (6), in the vicinity of the hubs (7). In order to make relief cuts (13, 13?) in the area between the hubs (7) and the upper area (5), a salt mold part (15) is placed on the respective window insert (14). The salt mold part (15) serves to produce the recesses (12, 12?) as well as the relief cuts (13, 13?) when casting the piston (1) and is washed out after the piston (1) has been cast.

The piston head has a piston crown on the underside of which at least two boss lands, each provided with a head boss and a head boss hole are connected. The piston skirt has at least two boss bodies, each provided with a skirt boss and a skirt boss hole. When the head and skirt are joined, the head boss holes and skirt boss holes are flush in relation to each other for accommodating a gudgeon pin. Each boss body has a recess in which the corresponding boss land is accommodated with the associated head boss so that the head boss hole and skirt boss hole are aligned flush relative to each other.

Abstract: The zone of weakening, which is designed as a slot (6a), is bordered by film material (7) on both sides according to length, i.e., across the direction of loading, which is indicated by the arrows F. Tearing (8) which progresses from the edge because of microscopic damage comes to a standstill at the slot (6a) at the latest, because stress peaks are dissipated here and the locally increased stresses are diverted into elements of the film material (7) which are under less stress. Other embodiments include a locally interrupted adhesive layer for separation of an upper film layer from a lower film layer, these two film layers being otherwise glued together. The adhesive-free recesses here constitute zones of weakening in the sense of the present invention. This therefore prevents tears from spreading from one film layer to the next. Furthermore, the propagation of tearing is counteracted due to the dissipation of stresses when a tear that forms in the film layer reaches the zone of weakening.
