  • Publication number: 20240159105
    Abstract: A motorized blind and a manual switching clutch structure thereof are disclosed. The motorized blind includes a blind assembly, a spring power module, an electric motor module and the manual switching clutch structure. The blind assembly includes a bottom rail which can be driven by the spring power module to move. The manual switching clutch structure is disposed between the spring power module and the electric motor module. By rotating a knob of the manual switching clutch structure, the motorized blind can be switched between a motor driving mode in which the electric motor module participates in the movement of the bottom rail by driving the spring power module, and a manual driving mode in which the spring power module individually participates in the movement of the bottom rail.

  • Patent number: 11952273
    Abstract: We disclose herein a viable, cost efficient method for the instantaneous production of hydrogen gas. Hydrogen gas production is increased by utilizing solar and lunar energy. The hydrogen gas is generated spontaneously by the reaction of sodium hydroxide and aluminum as corrosion occurs, forming a layer of aluminum oxide upon the aluminum. This aluminum oxide layer prevents further reaction of sodium hydroxide and aluminum, and thus no more hydrogen gas is produced. Production of aluminum oxide can be bypassed by adding acetic acid or sodium acetate to the reaction. In this reaction the products are aluminum hydroxide and hydrogen gas. Thus, we disclose herein a method that prevents of the formation of aluminum oxide by the use of sodium acetate or acetic acid, the use of iron as a catalyst, and the enhancement of the reaction using natural light.
