摘要： Compositions for various surfaces including glass, metals, ceramics, polymers, painted surfaces, and other durable non-porous materials clean surfaces while forming a durable, and long-lasting residual thin film. The thin film is self-cleaning, and can be self-disinfecting. The compositions include a combination of a surfactant and a nanoparticulate photocatalytic material (e.g., metal oxide), and may comprise additional elements such as antioxidants, perfumes, and disinfecting agents

摘要： An electromagnetic flow meter for measuring flow rate of a fluid passing therethrough includes a conduit defining a fluid inlet, a fluid outlet and a measuring section positioned between the inlet and the outlet. The flow meter also includes a single coil for generating a magnetic field across the measuring section and electrodes for detecting induced electrical potential due to the fluid passage. The flow meter also includes means for conditioning the flow through the measuring section. The combination of the single coil and the flow conditioning means provides a flow meter with a desired level of accuracy. The single coil and the electrodes may be arranged so that the integral of a weight function, which defines the sensitivity of the flow meter to fluid velocity through different parts of the measuring section, over the first half of a measuring section closest to the coil is between 0.4 and 1.3 times the integral of the weight function over the other half of the measuring section.
