Abstract: The present invention relates to a process and a device for dividing a tubular flagpole. This is achieved by introducing into the flagpole an elongated body, which over at least part of its length has a geometric shape, which in concert with a complementary geometric shape inside the flagpole ensures that the flagpole can be cut and assembled in a way that guarantees the rectilinear continuity of the flagpole. The complementary geometric shape is formed in that, after the body is introduced into the flagpole, a filling material is injected so that the space between the flagpole and the elongated body is filled. The flagpole is then cut around the elongated body down to the outer surface of the body so that the geometric shape allows the flagpole to be divided into two sections at the cutting side, the body remaining fixed to one of the sections.

Abstract: In an excavation bucket, the nose of an adapter has two surfaces to take the horizontal loads and four surfaces to take the vertical loads. A pin holds and locks a tooth to the adapter. Projections on the pin engage sloping surfaces of the nose. A recess placed ahead of the nose of the adapter will become visible as the tooth erodes due to wear. A recess at the nose of the adapter indicates that the tooth has worn too much and, unless the tooth is replaced, will commence to cause wear of the adapter and adjacent parts. To attach the adapter to the lip of the excavation bucket, wedge members are joined together near one end thereof to form a wedge-shaped block insertable into a wedge-shaped space formed by a C-clamp surface and a slot in the lip. The block is forced into the space, and spring biased teeth carried by the lock box progressively enter and leave the recesses in the outer surface of the C-clamp. When the C-clamp is tight enough in the gap, the installation of the lock box is complete.
