Abstract: A wearable inspection unit is provided. The wearable inspection unit includes at least one sensor configured to capture images based on a current view of the user, a media output component configured to display an augmented reality overlay to a user, and a controller. The controller is programmed to store a machine learning trained inspection model trained to recognize images of one or more components, receive a signal from the at least one sensor including a current image in the current view of the user, compare the current image to a trained inspection model to determine a classification code based on the comparison, determine a current step of a process being performed by the user based on the classification code, and provide a notification message to the user via the augmented reality overlay based on the current step of the process being performed by the user.

Abstract: An agent for the protection of material containing an N-sulphenylated benzenesulphonamide of the formula ##STR1## wherein R.sup.1, and R.sup.2 and R.sup.3 independently of one another represent hydrogen, halogen, nitro, alkyl or halogenoalkyl andR.sup.4 denotes an unsubstituted or substituted, saturated or unsaturated, aliphatic or cycloaliphatic radical, the aliphatic radicals being uninterrupted or heteroatoms or being interrupted by one or more hetero-atoms. The N-sulphenylated benzenesulphonamide-containing agents are useful for protecting industrial materials, for example, paints and timber, against attack by microorganisms, such as bacteria, fungi, yeasts, algae, slimes and viruses.

Abstract: Unsaturated polyester resins which are suitable for the production of cross-linked polyesters which are with difficulty to saponify contain, in part at least, radicals of 2-alkyl-1.3-propane diols as the alcohol component.

Abstract: Diphenylamine is made by heating aniline under pressure and temperatures of 250.degree.-400.degree. C in the presence of a boron/fluorine compound and water.

Abstract: Liquid stoving-lacquer systems based on oil-free polyesters obtained by reacting polybasic carboxylic acids or their anhydrides and 2-ethylpropane diol-1.3 and optionally additional polyhydric alcohols, are highly compatible with melamine resins.
