    摘要: An elevator cab ceiling includes an upper ceiling panel and a lower ceiling panel that are vertically spaced apart from each other with an intermediate ceiling cavity between them. An inlet duct is associated with the upper ceiling panel and an outlet duct is associated with the lower ceiling panel. The inlet and outlet ducts are horizontally spaced apart from each other and are fluidly connected to each other through the intermediate ceiling cavity to form a ventilation path. This separation of inlet and outlet ducts by an intermediate ceiling cavity reduces airborne noise transmissions that enter an elevator cab through the ventilation path. In one example, at least one baffle is installed within the intermediate ceiling cavity between the inlet and outlet ducts to interrupt a flow between the inlet and outlet to further reduce any transmitted noise.

    摘要: An escalator step (12) includes a sound barrier material (40) covering over at least a portion of an inner surface (42) of a tread portion(30) and an inner surface (44) of a rise portion (32). In one example, the sound barrier material (40) comprises a sheet of vinyl. The sound barrier material (40) reduces noise radiation from the step (12) toward a cavity (26) within a passenger conveyor support structure (20) and reduces noise emanations from the cavity (26) through the steps (12). Several embodiments for securing the sound barrier material (40) in place are disclosed.

    摘要: A method for operating a vibrating flow meter system is provided. The method includes the step of receiving a first sensor signal from a first vibrating flow meter. A second sensor signal is received from a second vibrating flow meter. A first flow rate is generated from the first sensor signal and a second flow rate is generated from the second sensor signal. The method further includes the step of determining a differential zero offset of the first vibrating flow meter based on the first and second flow rates.
