A powder conveyor has a pneumatically actuated dense phase powder pump and a pressure controller. The dense phase powder pump comprises at least one conveyor chamber having a powder inlet valve and a powder outlet valve. The pressure controller can be used to adjust and maintain a set pressure on the at least one conveyor chamber of the dense phase powder pump that is or can be previously defined and/or to adjust and maintain an actuation pressure on the powder inlet valve or the powder outlet valve that is or can be previously defined. The powder conveyor further comprises a gas flow detection device for detecting or determining a quantity of gas that is fed or removed per time unit when the set pressure is adjusted and maintained on the at least one conveyor chamber or a quantity of gas that is fed to the powder inlet valve or the powder outlet valve per time unit when the actuation pressure is adjusted and maintained. An evaluation device compares at least one detected or determined gas flow value with a corresponding set value and automatically generates an error and/or alarm signal when a deviation is detected.

A filament-transportation device has a plurality of tube elements for transporting filaments from an intake area to an outtake area via an airstream generated by underpressure or overpressure. Each tube element has an end orifice. A baffle-plate unit has a baffle plate having a through-hole, a top surface opposite to the end orifices to stop the transport of the filaments, and a bottom surface opposite to the top surface. The baffle plate includes baffle plate elements associated with the end orifices. Each of the baffle-plate elements has a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending between the top and bottom surface. There is a plurality of bridge elements, each having a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending from the top surface of the bridge element to the bottom surface of the bridge element. The through-hole is defined either by the side surfaces of at least two baffle plate elements or by the side surfaces of at least one baffle plate element and of a side surface of at least one bridge element not facing an end orifice of a tube element, which bridge element connects two spaced apart baffle plate elements from the plurality of baffle plate elements.

A modular tube volume reduction assembly for use at a vacuum tube vehicle station is provided. The assembly includes a modular station vacuum tube having a tube volume and a plurality of cavities longitudinally formed around a circumference of the modular station vacuum tube, and a volume reduction assembly integrated with the modular station vacuum tube, where the volume reduction assembly includes a plurality of blocks longitudinally coupled to a cavity interior of each of the plurality of cavities. The assembly includes a control system coupled between the modular station vacuum tube and the blocks. The control system radially moves the blocks to and from a vehicle outer surface of a vacuum transport tube vehicle at the vacuum tube vehicle station. The assembly displaces the tube volume between a station wall and the vehicle outer surface, and reduces the volume to be evacuated at the vacuum tube vehicle station.
