Abstract: A railroad switch actuator has a transversely extending box sleeper having a pair of ends, adapted to be secured to a pair of longitudinally extending fixed rolling rails, and adapted to slidably support a pair of longitudinally extending and transversely shiftable switch tongues. A switch rod extends transversely in the box sleeper, is connected to the tongues, is centered on a transverse axis, and is displaceable along the transverse axis to shift the tongues. A drive having an output shaft is supported on one end of the sleeper by a hinge for pivotal movement between a down position outboard of the one sleeper end and with the output shaft axially aligned with the switch rod and an up position between the sleeper ends.

Abstract: A coupling unit for coupling an optical transmitting and/or receiving module to an optical fiber connector. The coupling unit has a connecting region, which can be connected to a transmitting and/or receiving module, a receiving region, which receives an optical fiber connector, and a glass component, via which light is coupled directly between an optical fiber inserted into the receiving region and a coupled-on transmitting and/or receiving module. In this case, the coupling unit is formed as a plastic part apart from the glass component. The glass component is introduced into a bore in the plastic part.

Abstract: A rapidly deployable breakwater is disclosed having a primary barrier containing liquid under pressure, and one or more overtopping barriers. The primary barrier floats at, and extends substantially below, the surface of the water, while the overtopping barriers are positioned on the primary barrier and extend substantially above the surface of the water, the combination being adapted to attenuate wave action in open water. The liquid in the primary barrier is pressurized to a level substantially greater than the pressure of the surrounding water, and such pressure may be maintained or varied during the period of deployment of the breakwater.
