Abstract: A temperature control device for controlling the temperature of workpieces in particular for drying vehicle bodies, having a housing and a temperature control tunnel accommodated in the housing and having a tunnel floor. A transport system includes a plurality of transport carriages, which can be moved in a transport direction on a rail system, and by means of which the workpieces can be transported through the temperature control tunnel. Each transport carriage has a transport carriage chassis and a securing device for at least one workpiece, which are coupled together by means of a connection device. Each transport carriage carries a separate drive system, so that the transport carriages can be driven and moved independently of one another.

Abstract: An air supply track for positioning in a floor, and a probe for mounting on a vehicle which moves along the floor. An air supply track having a slotted conduit with the slot closed by a membrane urged against the slot by air pressure within the conduit. A probe movable into engagement with the membrane for moving the membrane away from the slot permitting air flow through apertures in the membrane into the probe and then into the vehicle.

Abstract: A railway vehicle having pneumatic actuated devices connected to a pneumatic system including a refillable supply tank connected to the control and actuation elements of the pneumatic devices is provided with a device for coupling the supply tank to a source of pressure medium as the vehicle approaches the source. The apparatus comprises a supply funnel on the vehicle connected to the supply tank and a supply nozzle connected to a source of pressure medium at a station. The supply nozzle is provided with receiver means. On the vehicle there is provided contact means which are engageable with the receiver means as the vehicle enters the station to align coaxially the funnel and nozzle and to impart relative longitudinal movement between the funnel and nozzle to couple these elements in tight coupled position. The funnel and nozzle are each provided with check valves which are opened simultaneously upon coupling of the funnel and nozzle.
