Abstract: A method and a network for routing data packet in a unified wide area network (WAN) is provided. The method includes encapsulating a data packet by an ingress aggregation router and forwarding the encapsulated data packet to an ingress backbone router. The encapsulated data packet includes a first label. The ingress backbone router selects an optimized traffic engineered tunnel and replaces the first label with the optimized traffic engineered tunnel and forwards the encapsulated data packet along the optimized traffic engineered tunnel.

Abstract: Animal drinking troughs have pressure reducers for reducing the higher pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. For various reasons, it is desired to change the reduced pressure. This takes place by adjustment of the pressure reducers. It is known to undertake such an adjustment with compressed air. This requires a separate compressed air source and a corresponding pipe system. The invention makes provision to adjust the pressure reducer hydraulically by means of the higher pressure of the liquid of the liquid supply. The energy required for adjusting the pressure reducers thereby provides the liquid pressure of the liquid supply. As a result, the pressure reducers according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers is not required.

Abstract: Described is a comminution device, in particular a comminution device including an adjusting mechanism, the adjusting mechanism including a hydraulic cylinder which is coupled between the first and the second cutting element and is in hydraulic communication with a closed hydraulic and pneumatic volume, which is filled with a hydraulic fluid in a first part and with air in a second part, and the wall of which is at least partially transparent so that the hydraulic fluid level can be read from a scale which displays a wear condition of the first and second cutting element. Also detailed is a comminution device in which a lubricant-filled cavity is formed between a first area and a second area, the volume of the cavity being reduced by an adjusting movement of the second cutting element and which is in fluidic communication with the positive engagement connection in order to supply lubricant to the positive engagement connection.

Abstract: The invention relates to a cutting device for macerating a free-flowing fluid-solid mixture, having a knife rotor which is mounted in such a manner as to be able to rotate relative to a cutting sieve. Said knife rotor abuts the cutting sieve axially with respect to the direction of its axis of rotation, and is pretensioned against the cutting sieve in the axial dimension. According to the invention, at least one clearance space is included, wherein the same is bounded by at least one first and one second surface, and the first surface is arranged in a manner such that it cannot be displaced in the axial dimension toward the knife rotor, the second surface is arranged in a manner such that it cannot be displaced in the axial dimension toward the cutting sieve, and the first and the second surfaces are arranged such that they cannot rotate about the axis of rotation of the knife rotor with respect to each other.
