Abstract: A drive device for moving a leaf, in particular a door leaf or a window leaf, with an electric machine including an, in particular single, stator and an, in particular single, rotor, which can be rotated about a machine axis, and with a gear coupled to the electric machine. The gear has a first gear element, which can be rotated coaxially with the machine axis, with the first gear element being connected to the rotor in a rotationally-fixed manner.

Abstract: A method for determining storage stability for a plurality of fluid lubricant samples of different lubricating oil compositions is provided. Each sample includes a combination of one or more base oils and one or more lubricating oil additives. The methods can advantageously be optimized using combinatorial chemistry, in which a database of combinations of lubricating oil additives or lubricating oil compositions containing such additives is generated. As market conditions vary and/or product requirements or customer specifications change, conditions suitable for forming desired products can be identified with little or no downtime.

Abstract: A high throughput preparation of a plurality of different lubricating oil compositions for combinatorial libraries and subsequent high throughput screening for lubricant performance is provided. The methods can advantageously be optimized using combinatorial chemistry, in which a database of combinations of lubricating oil compositions are generated. As market conditions vary and/or product requirements or customer specifications change, conditions suitable for forming desired products can be identified with little or no downtime.

Abstract: A method and system of transforming a product development process to reduce time in bringing a product to market through high throughput experimentation and advanced statistics and informatics, to transform the product development to a level of higher correlation with engine tests, and to develop better commercial products.

Abstract: A method for determining oxidation stability for a plurality of different lubricating oil composition samples is provided. The methods can advantageously be optimized using combinatorial chemistry, in which a database of combinations of lubricating oil compositions is generated. As market conditions vary and/or product requirements or customer specifications change, conditions suitable for forming desired products can be identified with little or no downtime.

Abstract: A combinatorial lubricating oil composition library is provided comprising a plurality of different lubricating oil compositions comprising (a) a major amount of a base oil of lubricating viscosity and (b) at least one lubricating oil additive. Methods for preparing same are also provided.
