The phosphor combination may optionally include a third phosphor that is a red-emitting phosphor with the formula (MB) (TA)3-2x(TC)1+2xO4-4xN4x:E. A conversion element may include the phosphor combination. An optoelectronic device may include the phosphor combination and a radiation-emitting semiconductor chip.

Abstract: A system and method for detecting a brake dragging during normal operation of a motor monitors torque at zero speed and at constant speed. For an inertial system acted upon by gravity, a value of torque required to maintain zero speed is approximately the same as a value of torque required to maintain operation at a constant speed. In an exemplary, elevator system, a motor drive determines the torque required to maintain zero speed operation of an elevator cab after a holding brake opens and before it begins controlling the motor to rotate. The motor drive again determines the torque required to maintain a constant speed and compares this value to the value of torque required to maintain zero speed. If the difference between the two values of torque is greater than a predefined threshold, then the motor drive determines that the brake is dragging and sets an error message.

Abstract: This invention relates to an air classifier for the separation of granular material into three fractions, whereby each individual fraction is very precisely separated in a single housing. The classifier incorporates motor-driven separator/classifying wheels each of which is provided with a tangential separating-air supply at the level of the respective wheel, a fixed guide vane ring positioned at a radial distance from the circumference of the respective separating wheel, and at least one bulk-product feeder system as well as discharge provisions for fine, intermediate and coarse material, respectively. The wheels are provided with a closed cover disk at their respective first axial end and with fine and, respectively, medium fraction discharge port at their respective second axial end. The closed cover disks of the wheels form a free-flow gap in the space between the two stages of the classifier.

Abstract: An electronic system may include a mounting structure that allows a switch to be firmly attached to the electronic system. The switch may have one or more snap lock mechanisms attached to a body of the switch. The mounting structure may have an opening sized to allow the switch and the snap lock mechanisms to be inserted into the mounting structure. The mounting structure may include an undercut portion in a wall of the mounting structure. The mounting panel may also include a channel configured to accept a width of the snap lock mechanism. The undercut portion of the wall may be located in a channel wall. When the switch is inserted into the mounting structure, the snap lock mechanism may engage the undercut portion of the mounting structure to securely hold the switch to the mounting structure.

Abstract: The method for air classification of toner used to develop electrostatic images, whereby a toner product consisting of a powder with a wide particle size distribution is converted into a higher-quality toner product with a narrow particle size distribution in that the residence time of the toner product is controlled by means of components, components which in the upper section of the classifying chamber quickly introduce the toner product in a homogeneous state into the classifying chamber, which in the central section of the classifying chamber permit a longer residence time of the toner product, and which in the bottom section of the classifying chamber permit rapid discharge of the toner product from the classifying chamber, all of which makes it possible to produce a toner end product with an extremely narrow particle size distribution.
