| 20100234517 | CURABLE COMPOSITIONS CONTAINING AQUEOUS DISPERSIONS OF ORGANOPOLYSILOXANES - Curable compositions are disclosed, containing at least one organopolysiloxane, which contains at least one hydroxyl group and/or group which can be hydrolyzed, in aqueous dispersion, i) at least one oganopolysiloxane having a dynamic viscosity of 0.05 to 7 (measured according to Brookfield DV-II+, spindle 3, 23° C.), which is free of hydroxyl groups and/or groups which can be hydrolyzed, in aqueous dispersion, at least one cross-linking agent, at least one emulsifier, at least one cross-linking catalyst, at least one aqueous silicon-free polymer dispersion, at least one filler, and optionally water. The compositions are suitable as sealants, adhesives, or coating agents for application in the construction field, in particular in the sanitary field and in the kitchen field. They are characterized in relation to aqueous silicone preparations known up to this point by an improved adhesion spectrum, in particular on plastic substrates. | 09-16-2010 |

| 20110204729 | SAFETY SWITCHING DEVICE WITH UNIVERSAL SIGNAL INPUT - The present invention relates to a safety switching device for actuating actuators in a fail-safe manner, and further relates to an emergency shut-off circuit comprising a safety switching device according to the present invention. The safety switching device includes at least one first and second safety input for receiving a first and second input signal, at least one first and second safety output for transmitting a first and second output signal, and a control unit for evaluating said input signals and for generating said output signals. The first and second safety outputs further comprise a feedback loop said that couples the output signals back to the control unit such that the control unit is operable to perform a test routine for testing said output signals. | 08-25-2011 |
