The invention relates to an inter-carriage passage for a railway carriage set comprising an intermediate bodywork member having a generally annular shape connecting the adjoining ends of two carriages. In accordance with the invention, the intermediate bodywork member is connected to the two adjoining carriage ends so as to be maintained in a radial position; this intermediate member is positioned on each carriage end by means of deformable pneumatic joints. The invention is especially applicabl...

An improved railroad coupler mount is provided for securely mounting railroad signalling and monitoring equipment (10) on the coupler of the last railroad car of a train. The railroad coupler mount includes a banana shape member (30) which extends through a pair of relief holes (22) in the knuckle (12) of the railroad car coupler. The railroad coupler mount has a tightening means (28) for partially withdrawing the banana shaped member and tightly pressing a support leg (20) against the side wall...

A modular floor for manual storage systems consists of floor modules joined to create a longitudinal path of any desired length for supporting a wheeled carriage for movement therealong. Each floor module comprises a pair of parallel rails that are independently vertically adjustable by means of leveling screws in transverse rail supporting beams. The ends of the rails are notched and tongue and grooved to provide vertical and horizontal alignment of the ends of adjoining rails. The modular floo...

A collector device for trolley-assisted vehicles having a pantograph operating circuit acting to deenergize the pantograph operating electromagnetic valve, when a driver inadvertently intends to leave the vehicle while pantographs are in the working position by automatically bringing the pantographs down to leave overhead contact wire thus to avoid electric shock accident.

A disk wheel, especially a railroad wheel, has a composite construction of single piece metal hub and a single piece metal rim connected to each other by a wheel disk of fiber reinforced composite material providing exclusively adhesive bonds. The wheel disk transmits shearing stress between hub and rim. The rim is provided with two radially inwardly extending rim flanges. The hub has two radially outwardly extending hub flanges. The shearing stress transmitting wheel disk (12) has a radially ou...

A tracking arrangement for a conveyorized transport system of the type in which coded workpiece carriers are routed by a switching mechanism from a main rail to an entry end of a subsidiary loop and then returned to the switching mechanism via a discharge end of the subsidiary loop, the entry end of the subsidiary loop being located downstream of the discharge end relative to the general direction of carrier movement on the carrier rail. The tracking arrangement comprises a sensor which reads th...

An assembly for suspending electricity power supply rails comprising a cross member (2), bolts (6) or the like for fixing the cross member to a fixed structure (4) in a direction which is perpendicular to the direction of the power supply rails (8), and members for suspending the rails from the cross member. The members for suspending the rails comprise: a series of at least two generally T-shaped half-clamp elements (10) comprising a crossbar (12) and a riser (14) perpendicular to said crossbar...

The invention relates to a rail securing arrangement, which has the following features. It comprises metal plates, each of which lies with its flat lower surface on the sleeper, and on whose upper surface two ribs are formed which extend in the longitudinal direction of the rail, and between which the foot of the sleeper lies on a bearing surface. On both sides of the rail in the region of the respective ribs, each plate has moreover at least one through-hole, with which a respective through-hol...

Apparatus for supporting a vehicle so that it can be moved sideways by manual force. The apparatus includes a floor part having a pair of spaced, generally parallel grooves. Each groove has a pair of roller members coupled to it, and the roller members of the two grooves are alignable with each other so that a vehicle can be driven onto the roller members and be supported thereby. Each roller member has a lower extension or lip extending into a respective groove so that, when a sideways force is...

A mobile robot remotely controlled and/or powered through a cable from a stationary console is provided. The robot carries a cable management arrangement which stores the cable and dispenses and retracts it as needed. The arrangement lays down the cable under zero tension when the robot is outbound and reels it in as the robot returns to allow the robot to follow a tortuous path without entangling the cable under or around obstacles. The robot can have numerous configurations such as a simple co...
