Abstract: The invention relates to a device for distributing a material in a molten state, said device comprising a swinging chute (16) supported so as to be capable of swinging about a substantially horizontal swinging axis (25), and a driving group (40). The latter comprises gear motor group (42), a drum winch (44) driven by the gear motor group (42), and at least one cable segment (50, 50?) that can be both wound on or unwound from said drum. One end of the cable segment (46, 50, 50?) is attached to the swinging chute (16) at a distance L from the swinging axis (25) thereof so as to apply a swinging momentum to said swinging chute (16).

Abstract: According to the present invention, a drill rod (10) comprises an elongate hollow shaft (12) with a first shaft end and a second shaft end (22), the first shaft end having a first connector for connecting the drill rod (10) to a drive mechanism, the second shaft end (22) having a first female tread (24); and an adapter (30) with a first adapter end (32) and a second adapter end (34), the first adapter end (32) having a first male thread (42) cooperating with the first female tread (24) of the second shaft end (22), the second adapter end (34) having a second connector for connecting a drill bit (46) thereto. When a drill bit (46) is connected to the drill rod (10), the adapter (30) is sandwiched between the hollow shaft (12) and the drill bit (46). The above configuration of drill rod allows a great variety of drill bits to be used in conjunction with a single hollow shaft. There is hence no need to provide a different hollow shaft if a different drill bit is to be used.
