A device for reducing and/or eliminating water noise. A screen made of waterproof material has small holes distributed across its entire surface, to reduce the size of water droplets exiting the screen to less than 5 mm.

A vibration damper (1) operating in accordance with the mass-spring principle, which is provided for fitting on an injection line pipe, includes a main body (2) which comprises an elastomeric vibration-damping material and has an inside hollow space (3) which passes therethrough in the longitudinal direction and which in the fitted condition surrounds the injection line pipe, the longitudinal axis (4) of the inside hollow space (3) coinciding with the longitudinal axis of the pipe, and is characterized in that it has a mass distribution eccentric with respect to its longitudinal axis (4) and can be non-rotatably fitted on the injection line pipe.

The present inventive concept includes a duct system and method for using same to map and locate ducts. A preferred embodiment of the duct system includes a duct, a plurality of electronic information modules and an oversheath at least partially covering the plurality of information modules and fixing the information modules to the duct. The plurality of information modules are configured to emit a positional signal to enable location of the information modules and associated duct(s) and/or mapping of the duct system.

Pipe joints and more particularly cylindrical push-on type pipe joint fittings with earthquake resistant functions.

A clamp assembly includes a body part having a recess of different sizes for holding an elongated structure with different sizes and shapes. A horizontal spaced T-slot is located on a first side surface of the body part at its top and a T-shaped protruding arm is located on a second side surface of the body part at its top. The clamp assembly includes a male locking section with an extended snap arm located on the first side surface of the body part at its bottom and a female locking section with a stopper located on the second side surface of the body part at its bottom. The T-shaped protruding arm is locked into the T-slot and simultaneously the male locking section is locked into the female locking section, such that the clamp assembly is detachably assembled with another clamp assembly.
