  • Publication number: 20240077042
    Abstract: A non-road mobile machinery (NRMM) is provided and includes a fuel storage device, a fuel supply device, a vapor adsorption device, and an engine body. The vapor adsorption device is provided with an air vent communicated to the atmosphere. A vapor discharge hole of the fuel storage device is communicated to an adsorption vent of the vapor adsorption device. The NRMM also includes a valve mechanism connected between a desorption vent of the vapor adsorption device and an intake channel of the engine body. The valve mechanism is conducted with the working of the engine body and blocked with the stop of the engine body. The NRMN improves the evaporation emission performance of the NRMM when compared to the prior art and solves the problem that the evaporation emissions of the NRMM in the prior art are prone to exceed the standard.

  • Publication number: 20220315066
    Abstract: A heat dissipation system for a high-speed train running in a low-vacuum tube is provided. Component groups that provide power and resistance for the movement and stop of a train are provided at a periphery, close to the train, in a low-vacuum tube. The component group is provided with a group A cooling assembly. The group A cooling assembly includes a group A cooling-type heat exchanger and/or a group A nozzle assembly attached to the back of the component group. Since the friction between the train running at high speed and the air in the low-vacuum tube and the operation of the key equipment in the low-vacuum tube will generate a lot of heat, the group A cooling assembly in the component group in the low-vacuum tube exchanges the heat with the air in the low-vacuum tube.

  • Publication number: 20200093858
    Abstract: This present disclosure discloses a bioadhesive boric acid formulation and its use and preparation method. Specifically, a preferred vaginal bioadhesive boric acid formulation mainly comprises of: methylparaben, propylparaben, potassium sorbate, chitosan, glycerin, carbopol 974, polycarbophil, boric acid, and purified water. The vaginal boric acid preparation are capable of retaining and releasing boric acid in the vagina. It is proved experimentally that boric acid acts as an antibacterial component of this gel and can be maintained at a relatively high concentration in vaginal fluid. Further, it is demonstrated that the vaginal bioadhesive boric acid formulation has a dynamic viscosity >100000 cps, pH value of 2-5, good moisture retention capability. The formulation is non-allergenic, non-vaginal irritation, and capable of inhibiting bacteria and fungi.

  • Publication number: 20180104346
    Abstract: This invention discloses a bioadhesive boric acid formulation and its preparation method. Specifically, preferred vaginal bioadhesive boric acid formulation mainly comprises chitosan, carbopol 974 , polycarbophil, boric acid, and purified water as a gel. The main performance characteristic of this vaginal boric acid preparation is the ability of the formulation to retain and release boric acid in the vagina by using a combination of carbopol 974 and polycarbophil as preferred bioadhesive polymers. It was proved experimentally that boric acid as the antibacterial component of this gel can be maintained at a relatively high concentration (>10 mg/mL) in vagina for an extended period of time (>2 hours) with the use of a combination of polyacrylic acid polymers, i.e. carbopol 974 and polycarbophil.

  • Publication number: 20140242098
    Abstract: Flexible film or strip dosing device and method for various therapeutic applications are disclosed. The device includes at least one film or strip and a packaging container for the film or strip. The film or strip normally include a polymer base with or without a therapeutic agent admixed with the polymer base. The film or strip is printed with doses, marks or calibrated lines to indicate different length of the film and therefore the different doses of the therapeutic agents. The packaging container or dispenser can have marks or calibrated lines similar to a ruler which measures the length of film and therefore the different doses of therapeutic agents. The packaging container may have a built-in cutter to conveniently cut the film or strips as needed for flexible dosing of therapeutic agents.
