摘要:
Bacitracin, bacitracin derivatives and other oligopeptides, alone or in the form of oligopeptide-metal ion complexes, are shown to be useful as bleach catalysts incorporated in washing and cleaning agents for the cleaning of soiled hard surfaces and textile fabrics. These catalysts may be used in conjunction with hydrogen peroxide or any alternate bleaching agent, or used simply in the presence of atmospheric oxygen to bleach stains. New and novel oligopeptides and their metal ion complexes are disclosed herein, along with methods for the cleaning of hard surfaces and textile fabrics with washing and cleaning agents incorporating these bleach catalysts.

A bed comprising a bottom platform for securing to a surface of a vehicle and a horizontal riding platform coupled to the bottom platform by a horizontal motion interface which allows relative horizontal movement between the horizontal riding platform and the bottom platform. A top platform is coupled to the horizontal riding platform by a frame assembly which allows relative vertical movement between the top platform and the horizontal riding platform, such that the top platform is moveable between a lowered position and a raised position. A biasing mechanism is located between the top platform and the horizontal riding platform for selectively biasing the top platform toward the raised position.

An optoelectronic sensor for sensing wetting of a windshield includes a first circuit, and a radiation emitter and a radiation detector both arranged on the first circuit to emit radiation toward the windshield and to detect radiation reflected from the windshield. Beam shapers parallelize the emitted radiation toward the windshield and focus radiation reflected from the windshield toward the detector. A coupling element couples the emitted radiation into the windshield and couples the reflected radiation out of the windshield. A structural element is arranged between the lens holder and the coupling element. The structural element may have retaining elements for positioning a second circuit arranged between the lens holder and the structural element relative to the windshield. The structural element may have support elements for adjustably positioning the lens holder and thereby the beam shapers relative to the first circuit and the windshield.

A sensor for detecting moisture on a pane includes a coupler having prisms arranged in coupling areas for coupling light from a transmitter into the pane at an input angle and prisms arranged in decoupling areas for decoupling light reflected from the pane to a receiver at a corresponding output angle. The prisms in the coupling areas have prism surfaces perpendicular to the input angle and the prisms in the decoupling areas have prism surfaces perpendicular to the output angle. Each prism includes a prism flank. The prism flanks in the decoupling areas may be arranged parallel to the output angle. Some of the prism flanks in the decoupling areas are opaque or roughened. Alternatively, some of the prism flanks in the decoupling areas are tilted from running parallel to the output angle. Alternatively, some of the prism flanks in the decoupling areas include at least one additional superimposed prism.

摘要:
A method is proposed for vacuum-coating a substrate using a plasma-CVD method. In order to control ion bombardment during the vacuum coating, a substrate voltage, produced independently from a coating plasma, is applied to the substrate. The substrate voltage is modified during the coating. The substrate voltage is a direct voltage that is pulsed in bipolar fashion with a frequency of 0.1 kHz to 10 MHz. A wear-resistant and friction-reducing multilayer structure of alternating hard material individual layers and carbon or silicon individual layers is proposed.
