Abstract: Disclosed are novel conjugates and methods for the preparation thereof. One of the methods for the preparation of a conjugate comprises a step of: acting a compound of formula (I), with a thiol-containing molecule of formula (II), wherein represents an amino acid, a peptide, a protein, an antibody, a nucleotide, an oligonucleotide, a saccharide, a polysaccharide, a polymer, a small molecule, an optionally substituted C1-C8-alkyl, an optionally substituted phenyl, or an optionally substituted aromatic 5- or 6-membered heterocyclic system; resulting in a compound of formula (III).

Abstract: Described herein are quaternary ammonium polymers and interpenetrating polymer networks and compositions thereof with broad spectrum antimicrobial properties that produce fast acting, long lasting, non-toxic and non-allergenic colorless and transparent durable surface coatings that are resistant to water and common solvents. The surface coatings are easy and cost effective to produce from readily-available materials using versatile synthesis enabling a wide range of chemical variations. They are readily applied to a wide range of surfaces and materials, and no materials leach out of the coatings.

Abstract: A filter module, including a plurality of filter elements for separating overspray from an air flow, the filter module including a reusable and cleanable frame configured as a support structure for components for collecting overspray, and a plurality of components inserted into the frame for collecting overspray, wherein the components for collecting overspray are at least filter elements and linings in the frame, which are configured as disposable, single-use products the filter elements form at least a first filter stage, and all the surfaces of the frame which are exposed to the air flow upstream of the first filter stage are provided with the linings such that the surfaces of the frame are protected against overspray.

Abstract: A filter for cleaning air includes: a housing; layers of a filter medium, the layers being arranged in the housing; and separator plates. One separator plate is arranged between each two layers of the filter medium. The separator plates are provided with a perforation. In an embodiment, the separator plates are fluted, corrugated, or folded.

Abstract: Apparatus for detecting a proper wearing status of a safety belt of a safety belt assembly in a motor vehicle includes a sensor device which is at least partially disposed in or on the safety belt and configured to output a sensor value as a function of a dependency on a disposition of the safety belt. An evaluation device determines in response to the sensor value output by the sensor device, whether an occupant of the motor vehicle properly wears the safety belt.

Abstract: A filter for purifying air includes a frame, layers of a filter medium, and separator plates. The layers of the filter medium and the separator plates are arranged in the frame. The layers of the filter medium are aligned at a distance from each other and one of the separator plates is arranged between each two layers of the filter medium. The separator plates are folded and are provided with folding in such a way that the separator plate is designed with a number of fold peaks and fold valleys on its first side and a multiple number of fold peaks and fold valleys on its other, second side. The fold peaks and fold valleys extend from the first side to the second side. The folding, as viewed in the flow direction, causes a trapezoidal cross-section of a respective separator plate.

Abstract: An apparatus for proper application of a seat belt in a vehicle. The apparatus includes the seat belt and a seat belt buckle which is assigned to it and which is provided with a measuring device, arranged for measuring a tensile force exerted on the seat belt buckle. The apparatus further relates to an evaluation device for evaluating the measured tensile force. At the same time, it is provided that the apparatus is also equipped with a tightening device for applying a tightening force to the seat belt, as well as with a detection device for detecting the applied tightening force. The evaluation device compares the tensile force to the tightening force and determines based on a corresponding comparison result whether the seat belt has been properly placed and secured in the seat belt buckle.

Abstract: The invention relates to a novel hetero-Diels-Alder crosslinker, to a process for the production thereof and to the use thereof for reversibly crosslinking polymer systems.
