Abstract: A method for determining a lateral mode stiffness of one or more fluid tubes (103A, 103B) in a vibrating meter (5) is provided. The method comprises a step of vibrating at least one of the one or more fluid tubes (103A, 103B) in a drive mode vibration. Drive mode sensor signals (310) are received based on a vibrational response to the drive mode vibration. At least one of the one or more fluid tubes (103A, 103B) is vibrated in a lateral mode vibration, wherein the lateral mode is approximately perpendicular to the drive mode. Lateral mode sensor signals (317) are received based on a vibrational response to the lateral mode vibrations. The method further comprises determining a lateral mode stiffness (318) based on the lateral mode sensor signals (317).

Abstract: 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.

Abstract: 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.

Abstract: An elevator load bearing assembly (20) includes a plurality of cords (22) within a jacket (24). The jacket has a plurality of grooves (32, 34, 36, 38 40) spaced along the length of the belt assembly. Each groove has a plurality of portions (50, 52, 54, 56) aligned at an oblique angle (A, B) relative to a longitudinal axis (48) of the belt (20). In one example, the grooves are separated such that there is no longitudinal overlap between adjacent grooves. In another example, transitions (60, 64) between the obliquely aligned portions are at different longitudinal positions on the belt. Another example includes a combination of the different longitudinal positions and the non-overlapping groove placement.

Abstract: 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.
