  • Patent number: 11931766
    Abstract: A plural material dispensing system (10) includes a pump (38) having a cylinder (52) mounted between a first bracket (32) and a second bracket (34), a piston (54) disposed within the cylinder (52), and a pump rod (48) extending from the piston (54) and out of the first bracket (32). Material is provided to the cylinder (52) through a flow path extending through the pump rod (48). The piston (54) drives material downstream out of the cylinder (52), and the interface between the piston (54) and the inner surface of the cylinder (52) provides a dynamic seal during pumping. The flow of material into and out of the pump (38) is controlled by actively-controlled inlet and outlet valves.

  • Patent number: 11319675
    Abstract: The present invention provides an aramid nanofiber (ANF)-based insulation paper and a preparation method thereof, and relates to the technical field of composite insulation material. The ANF-based insulation paper provided in the present invention includes ANFs and inorganic insulation materials. The ANFs have a bifurcated geometry and form a three-dimensional network structure, and the inorganic insulation materials are distributed in the three-dimensional network structure. The ANF paper provided in the present invention, with optimal electrical and mechanical properties and excellent insulation and flame-resistance, can replace mica tapes, aramid papers and aramid mica papers on the current market for insulation, and thus the thickness for insulation can be reduced. The present invention provides a method for preparing the ANF-based insulation paper.

  • Publication number: 20150318689
    Abstract: A System and a method are disclosed for suppressing rush current noise in a power switch cell. The system comprises: a power switch (306) having an operational condition dependent upon the state of a control signal; and an inrush current limiter module (300) for outputting the control signal. The control signal transitions from a first value to an intermediate value and from the intermediate value to a second value, wherein the power switch is configured to operate in a low conductive (OFF) condition when the control signal has the first value, to operate in a high conductive (ON) condition when the control signal has the second value, and to operate in a moderately conductive condition when the control signal has the intermediate value. Therefore, when the power switch transitions from the OFF condition to the ON condition, the rush current noise may be reduced.
