An anchor rod assembly is used for being fastened into synthetic resin mortar and contains an anchor rod with a shall portion, a fastening portion, and a head having a cutting edge, and contains a sleeve-like additional element which surrounds the fastening portion at least in some regions.

Anchor rod assembly with conveying head

A dispensing system includes a dispensing apparatus and a cartridge device. The dispensing apparatus has at least one receiving chamber for receiving the cartridge device, at least one dispensing device, a control device, a drive device and a power supply. The method includes inserting the cartridge device into the at least one receiving chamber; emitting at least one first signal from a signal generator of the cartridge device; receiving the at least one signal of the cartridge device by at least one sensor of the dispensing apparatus; transmitting a second signal from the sensor to the control device; transferring the drive device from a first operating mode into a second operating mode if the second signal corresponds to a value stored in the control device or if an algorithm stored in the control device verifies the second signal, or transferring the drive device into a third operating mode.

A process for operating an extrusion system is provided. An extrusion device is provided that has at least two extrusion pistons operable with different feed ratios. The process involves storing a ratio of feed rates of the extrusion pistons in a storage device of the control device in dependence on the second signal. A least one drive device is actuated by the control device for displacing the two extrusion pistons into a start position, in which a plunger of the first extrusion piston substantially abuts the first cartridge of the cartridge device and a plunger of the second extrusion piston substantially abuts the second cartridge the cartridge device. The at least one drive device is actuated by the control device with a ratio of feed rates stored in the storage device of the control device for the extrusion pistons at user request.
