Abstract: Examples are disclosed relating computer simulation environments that comprise output models producing output data and input models waiting for a portion of output data. One example provides a computing system comprising a scheduler configured to determine if prerequisite data is available for each input model. On condition that the prerequisite data is available, the input model is stepped. The output models and input models are maintained within a predetermined number of steps of each other. A router is configured to, when a selected output model finishes a step, copy the output data from an output buffer of the selected output model and send the output data to an output queue. The output data is stored until a selected input model is ready to step the selected frame. The output data is then copied from the output queue into an input packet buffer of the selected input model.

Abstract: Coating compositions may combine durability and stain resistance with reduced environmental emissions and health risks. A coating composition may comprise an isocyanate component, an amine-functional resin comprising an aspartic amine, a reactive silicone component having a molecular weight of at least of 500, and TiO2 in an amount of at least 5 wt. %. The coating composition may further comprise a cure retardant in an amount of at least 5 wt. % and a solvent in an amount of up to 20 wt. %.

Abstract: A condition-responsive electric switch mechanism having a snap-acting bistable spring switch element carrying a movable contact, and an actuator movable in response to a detected condition to operate the bistable spring switch element. The spring switch element is capable of snapping between a circuit open position in which the movable contact is spaced from a fixed contact and a circuit closed position in which the movable contact engages the fixed contact. The spring switch element has a head mounting the movable contact thereon, and a pair of arms extending outwardly from the head being formed free of connection to one another at their distal ends opposite the head. The arms are fixed to a first terminal blade at their distal ends in a configuration deflected from the relaxed position so as to stress the switch element making it capable of snapping between the circuit open and circuit closed positions for a wide variety of preset contact gaps.

Abstract: Herbicides containing a mixture of a cyclohexane-1,3-dione derivative of the formula ##STR1## where R.sup.1, R.sup.2, R.sup.3, Y and n have the meanings given in the description, and a 3,6-dichloro-2-picolinic acid derivative of the formula ##STR2## where R has the meaning given in the description. These herbicide mixtures display a synergistic action, especially on grassy plants.
