  • Patent number: 11116230
    Abstract: The present invention relates to a method for three-dimensional microwave air-jet drying of persimmon slices, comprising steps of grading and cleaning, slicing, microwave heating, steam de-astringency, hot-air reverse primary drying, negative-pressure intermittent secondary drying, cooling and packaging. In the present invention, high-temperature (60-70° C.) high-pressure annularly sprayed citric acid and 40% alcohol vapor (rotating at 360°) are adopted to remove astringency of persimmons, wherein high temperature causes more intense Brownian motion of liquid molecules; high pressure improves permeation and diffusion speed of de-astringency liquid in the persimmon slices; citric acid plays a membrane breaking role on persimmon cell membranes; and 40% alcohol vapor is allowed to rapidly diffuse into cells, so that tannin is polymerized into insoluble gel from a soluble state, thereby achieving a uniform and rapid de-astringency effect.

  • Publication number: 20210273551
    Abstract: A neutral-point voltage balance control method and system for a three-level converter in a full power factor range. The method includes: using a large, medium, and zero vector modulation method to synthesize a reference voltage vector, and duty cycles of a large vector, a medium vector, and a zero vector; obtaining a voltage difference between two dc-link capacitors of signal acquisition, and the voltage difference as a neutral-point potential of the three-level converter; according to a value relationship between the neutral-point potential of the three-level converter and a specified threshold, selecting a small vector and calculating a duty cycle of the small vector; and updating a duty cycle of each basic vector, and obtaining a switching sequence for controlling a power switch of a three-phase bridge arm. An amplitude of a common-mode voltage of an NPC three-level converter is equal to one sixth of a dc-link voltage.

  • Patent number: 8360535
    Abstract: An idler having an axis of rotation. The idler may include a hub with a flange. A plurality of rim members are positioned along a perimeter of the flange and have generally axially facing, opposite side surfaces. At least one of the side surfaces has a first interlocking formation. A clamping plate is connected to the flange. The clamping plate has a second interlocking formation coupled with the first interlocking formation. A dampening member interposes the first and second interlocking formations.

  • Patent number: 7905559
    Abstract: An isolated center tread rim idler is disclosed. The isolated center tread rim idler includes an idler body, and a circular rim including a radially outer portion configured to engage track bushings of a track assembly. The circular rim also includes a radially inner portion of less width than the radially outer portion. The radially inner portion is configured to cooperate with an outer circumferential surface of the idler body. The circular rim includes a curved transition portion between the radially outer portion and the radially inner portion. A resilient ring engages the curved transition portion. A side plate is fastened to a side of the idler body, and the side plate includes a portion engaging the resilient ring.

  • Patent number: 7776451
    Abstract: A method of forming a composite overlay compound on a substrate includes forming a mixture including at least one component from a first group of component materials including titanium, chrome, tungsten, vanadium, niobium, and molybdenum. The mixture also includes at least one component from a second group of component materials including carbon and boron, and the mixture further includes at least one component from a third group of component materials including silicon, nickel, and manganese. The mixture of selected component materials is then applied to a substrate material to form an overlay compound on the substrate material. The overlay compound is fused to the substrate to form a metallurgical bond between the substrate material and the overlay compound.
