Abstract: A spray head is provided for a blower tube of a spray apparatus. The blower tube is adapted to conduct a blower air flow to the spray head (20) in a flow direction (18). The spray head includes a supply pipe (13) for a medium to be sprayed such as a liquid. The spray head also includes an inlet opening for receiving the blower air flow (40) and an outlet opening through which the blower air flow is discharged from the spray head enriched with the medium. The supply pipe (13) has an outer feed connection for the medium and a discharge opening (29) in the interior of the spray head for admixing the medium into the blower air flow (40). The discharge opening (29) defines a plane aligned in the flow direction (18) and an impediment is disposed at the edge of the discharge opening lying upstream with respect to the flow direction (18). The impediment disturbs the blower air flow entering the spray head through the inlet opening before it flows over the discharge opening.

Abstract: A protective shield for a trimmer having a cutting head that is rotatable about an axis of rotation and supports a cutting thread that rotates about an axis of rotation with the cutting head and determines a cutting circle, covers at least partially the cutting circle. The protective cover has a base member and a cutting-to-length blade arranged on the base member so as to be positioned circumferentially relative to a cutting circle of the rotating cutting thread. The cutting-to-length blade has a cutting edge that, relative to the axis of rotation of the rotating cutting thread, is arranged in an axially displaced position displaced in an axial direction relative to the cutting circle. A device for axially deflecting the rotating cutting thread out of the cutting circle to the cutting edge is provided.

Abstract: Load balancing method and system for balancing a processing load in a network, wherein load balancer upon receiving a client request selects one of a plurality of processing servers for serving the request. The selection of a processing server may be based on a location of a client and a processing server. The load balancer may comprise a load balancing master and a plurality of load balancing slaves, wherein the load balancing slaves receive client requests and transmit a selection request message to the load balancing master. The load balancing master selects a load balancing slave and/or a processing server for serving the request and generates a corresponding instruction message. The client request is served by the selected load balancing slave and the selected processing server by establishing a communication link between the client and the processing server.
