Abstract: An air filtration system with vertical construction includes a suction intake for taking in contaminated air and vertical channel. Contaminated air is taken in and conveyed downward through the vertical channel which includes a lateral opening, through which the air flow is deflected toward and conveyed through a material pre-separator. A process chamber having at least one filter element is provided downstream of the material pre-separator. A fan is provided downstream of the process chamber. The material pre-separator has an intake side and an outlet side for a particle-contaminated air flow and consists of several strip-shaped separating elements that are arranged vertically on top of one another. The separating elements are initially arranged from the top toward the bottom with an increasing positive angle relative to the vertical line and at least one lower separating element has a negative angle relative to the vertical line.

Abstract: A mounting device for mounting a capacitor on a connector element includes a hollow body defining a continuous through-hole that axially penetrates the body for receiving and mounting the capacitor. The body has a lower region defining a lower through-hole portion with a dimension. The body further has a middle region defining a middle through-hole portion with a dimension that is smaller than the first through-hole dimension. Therefore, the middle region and the lower region define a first inner shoulder between them. The body further has an upper region defining an upper through-hole portion with a dimension that is smaller than the second through-hole dimension. The upper region and the middle region define a second inner between them.

Abstract: A digital frequency generating device is comprised of a first digital frequency generator which generates a first output signal at a first frequency and a second digital frequency generator which generates a second output signal at a second frequency independent of the first frequency. Both the first and the second frequency generators run continuously and either can be connected to the generating device output by means of a multiplexer. Apparatus is provided to synchronize the two generators so that a continuous phase transition is maintained when the generating device output switches from the first output signal to the second output signal. This arrangement allows the device output to be shifted from a first frequency to a second frequency and then return to the first frequency output while maintaining the phase position of the first frequency output and is particularly useful in nuclear magnetic resonance applications.
