A road-finishing machine for producing a paving layer from a laying material or a charger vehicle for supplying the road-finishing machine with a laying material. The road-making machine comprises a material bunker, and a pushing means fixed forward of the material bunker at a chassis, such that pushing rollers of the pushing means may dock to rear tires of a truck. The pushing rollers comprise a pair of first pushing rollers mountable in a first position in a seat of a traverse of the pushing means. Either the pushing means is expandable by at least one changeable attachment to which the first pushing rollers may be mounted in a second position further forward with respect to the first position, or the pushing means comprises a pair of second pushing rollers which may be selectively positioned forward of the first pushing rollers.

The invention relates to a system (1) comprising a feeding device (2) comprising a channel (6) having an inlet (8) and an outlet (10) and a feed screw (12) for conveying biomass material through the channel. The feed screw comprises a screw flight (12b) that extends from a first end (12c) to a second end (12d) and is adapted to form a gas impermeable plug of biomass. The system comprises at least one primary measuring unit (14; 16) adapted to continuously measure a primary variable indicative of the gas permeability of the plug, which primary measuring unit is connected to said feeding device between the first end of the screw flight and the outlet; and a control unit (3) adapted to use said primary variable values to monitor the gas permeability of the plug. The invention also relates to a method for preventing blow back in the above described system.

Disclosed is a system for transferring fuel pellets from a location external to a building to a location in an interior of the building. The system includes a first container positioned at a location remote from the building and a second container positioned proximate an exterior portion of the building. The first and second containers are connected to one another to permit the transfer of fuel pellets from the first container to the second container by a pneumatic apparatus. The second container is also connected with the interior of the building to permit the transfer of fuel pellets from the second container to the interior of said building.

A dry bulk tank and a method of carrying a load and discharging a load therefrom. The dry bulk tank includes a tank assembly having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.

The invention relates to a base station (10) for stationary emptying of a dirt space (41) of a mobile cleaning apparatus (40), comprising a dirt path (11) through which dirt can be transported out of the dirt space (41) of the cleaning apparatus (40), wherein a path input of the dirt path (11) is formed by a coupling element (12) which can be coupled to the cleaning apparatus (40) for emptying of the dirt space (41). Furthermore, the invention relates to a cleaning system (1) and a method (100) for stationary emptying of a dirt space (41) of a mobile cleaning apparatus (40).

A tank and a method of holding a load and discharging a load therefrom. The tank includes a body having a first wall that bounds and defines a first compartment for holding a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure.
