摘要： A safety breathing apparatus has a sensor for measuring the difference in pressure between two point 1a, 1b in the gas delivered to a head unit 9. The sensor is used to measure the difference in the pressure of the gas supplied through the apparatus between the two points in the gas flow, and the pressure difference is then used to calculate the gas flow rate.

摘要： The present invention relates to a cable protection system, and in particular to a cable protection system used to channel and protect cables or flexible pipes such as computer network cables, power cables, fiber optic cables, and hydraulic or pneumatic control lines laid within a cavity.The cable protection system comprises a sheet (10) of non-metallic material which may be shaped to form a channel. The cable protection system is adapted to fit between spacing bars (18) in a false floor, wall or ceiling.

摘要： Ambient or static pressure in a fluid stream is sensed with a hollow circr cylinder placed normal to the fluid stream. A shroud is mounted on the cylinder for adjustment over a ring of ports provided in the cylinder. In this manner, the relationship between the internal pressure in the cylinder and the ambient pressure is controllable. Ideally, the internal and ambient pressures are exactly equal. Further, extension of the cylinder above and below the shroud provides symmetry for positive and negative angles of attack.
