Abstract: A railroad track including rails and transversely extending ties. The end portions of the ties are placed on a rigid substructure. For reducing the sound emission, loading members are placed on the ties between the rails. These loading members have an essentially T-shaped cross-section, wherein the horizontally projecting portions are placed on adjacent ties. Sound-insulating elastic inserts may be provided between the ties and the loading members. Consequently, no fittings for fastening the loading members are required. In addition, the space existing between the ties is utilized in an optimum manner by filling it with sound-insulating material.

Abstract: The invention relates to a multi-speed hub for bicycles or the like having a gear shift system for more than three gears, wherein the hub transmission comprises a single planetary transmission with axially fixed planet carriers with stepped planet gears and with two different sun wheels, control of the hub transmission taking place coaxially through the hub shaft, there being for the gear shift elements in the hub a single control system which has to be operated from only one side of the hub shaft, the hub further comprising an arrangement of concentric separate sleeve-like components which are in functional sequence subject to the action of a shift head guided in the hub shaft and subject to spring tension. Such a construction provides a multi-speed hub which has an unusually large number of selectable gear stages, all of which can be operated from one axial side of the hub and by a single shift device and in functional sequence, actuation of this multi-speed hub being simple and functionally reliable.
