  • Publication number: 20210222704
    Abstract: A fan has an external rotor motor with a motor section and an electronics section. The motor section and the electronics section are arranged axially adjacent to each other along the axis of rotation. The fan, when operated as intended, generates, via the fan wheel, a pressure difference between its suction side, which is preferably associated with the rotor, and its pressure side, which is preferably associated with the motor electronics. A continuous cooling duct runs within the external rotor motor from a pressure-side inflow opening, at least along sections of the rotor, to a suction-side outflow opening. An exclusively passive cooling air flow through the cooling duct can be generated in operation by the pressure difference generated by the fan wheel.

  • Patent number: 10743184
    Abstract: Certain features relate to unequal distribution of transmitters and receivers in a distributed antenna system (DAS). Remote units in the DAS can be configured as transmitting remote units, receiving remote units, or remote transceiver units that can transmit and receive wireless signals. In some configurations, the DAS can be configured with a greater number of transmitting remote units than receiving remote units. In other configurations, the DAS can be configured with a greater number of receiving remote units. In some aspects, unequal distribution of transmitters and receivers can be obtained by allocation of transmission frequencies and receiver frequencies in the DAS.

  • Patent number: 10676569
    Abstract: The invention relates to a process for continuously preparing polyamide oligomers. This comprises continuous conveying of an aqueous solution of polyamide-forming monomers from a reservoir vessel into an oligomerization reactor, heating of the aqueous solution beyond a dissolution or storage temperature, the residence time of the monomer solution in the oligomerization reactor being limited and the pressure or the partial vapor pressure of the water being adjusted such that a conversion of monomers to polyamide oligomers does not exceed a maximum value and/or the polyamide oligomers formed do not phase-separate or spontaneously crystallize in solid form, and continuous discharge of the polyamide oligomers from the oligomerization reactor. A polyamide oligomer preparable by this process can be provided continuously in a mixture with water in a process for preparing a semicrystalline or amorphous, thermoplastically processible polyamide and then postcondensed to give a polyamide.

  • Publication number: 20200171746
    Abstract: The invention relates to a container for holding a photosensitive liquid for use in a stereolithographic system in which a reference layer is exposed to radiation for the layer-by-layer or continuous creation of workpieces. At least one element of the container which is directly adjacent to the reference layer consists of at least one material which is at least partially transparent to the radiation and at least some of which has structures and/or pores which can receive and discharge, preferably also store, an inhibitor and/or an inhibitor mixture. Therefore, the element is not just able to supply the inhibitor but to a significant extent consists of the inhibitor itself, as a result of which the supplied flow is equalized or homogenized. Rapid or even continuous 3D printing is thus made possible in a cost-effective manner.
