摘要:
A measuring device includes a signal-processing unit for the registration of a first signal in the time domain and a histogram-generating unit for the indirect generation of a histogram in the frequency domain from the first signal. The histogram-generating unit provides a frequency grid-point variation unit.

The present invention is directed to an insertion tool (12) for a machine tool that has a hub (16) with at least one opening (42, 80) for insertion of a fastening means (40, 84), via which the hub (16) is clampable on a driving flange (22) of the machine tool connected to a drive shaft, the opening (42, 80) including a retaining region (54) and a releasing region (56), the releasing region (56) including a stop (66, 88) for limiting a release motion of the fastening means (40, 84).It is provided that the opening (42, 80) adjacent to the stop (66, 88) has a convex section (76, 90).
摘要:
A method for producing a protein of interest on a manufacturing scale is based on integration, by homologous recombination, of the DNA encoding the protein of interest into a bacterial cell genome at a pre-selected site. The manufacturing scale production of recombinant proteins is in the fed-batch mode, semi-continuous or in a chemostat.
摘要:
A method for digital triggering of a digital recording of a digitized measurement signal having a superimposed noise signal. The method includes generating from the digitized measurement signal a digital triggering signal for the digital triggering of the digital recording of the measurement signal, and performing band-limitation of the noise signal superimposed on the digitized measurement signal via a low-pass filtering before the digital triggering signal is generated. The bandwidth of the low-pass filtering is adjusted dependent upon edge steepness of the measurement signal, in order to reduce variance σt2 in jitter of the digital triggering signal.

Known household appliances for integrating into a sector of a worktop include an operating strip containing at least one operating element and having a supporting surface on the lower side thereof for supporting the household appliance on the worktop, and a housing part provided with a fixing flange to which the operating strip is fixed. The invention aims to produce the operating strip in a simple manner with high dimensional accuracy. To this end, the operating strip is produced primarily by forming or milling.

An adjusting device for a domestic appliance, in particular, a cooking appliance, has at least one at least two-dimensional sensor area for setting at least one set point. The adjusting device includes an arithmetic unit operable to take into account at least one characteristic, depending on a user position, when setting the set point.

A plastic support with a transponder having a data memory for the wireless transmission data from and to the plate-like plastic support is provided with attachment means for attachment to objects to be electronically marked. The transponder is arranged on or in a transponder support separate from the plastic support, which is able to be joined to the plastic support by catch or clamping means. Accordingly a transponder support provided with the transponder is able to be reused, after its intended first use, in a new plastic support. Accordingly overall costs may be substantially reduced.

摘要:
Subject matter of the present invention is a drilling fluid additive based on sulfonated asphalt, which comprises a water soluble and anionic polymer component in quantities of 0.1 to 20 wt. %, with respect to the total additive in addition to the asphalt component. With this additive the water solubility of sulfonated asphalt can be markedly increased. This additive, whose polymer component is thermally highly stable, is utilized primarily in water- and/or oil-based drilling fluids and in particular in the exploration of subterraneous petroleum and natural gas deposits. Typical polymer components to consider are representatives of polycondensation products, such as phenol resins, ketone resins and sulfonated naphthalene, acetone and amino plasticizer resins (for example urea and melamine resins).
