Title: Flash removal from inside welded pipes - using appts. with pivoted cutting tool holders supported by rollers
Inventor: PATON BORIS EVGENIEVIC
IPC: B23D79/02
Filed: 1980-11-20
Abstract: The flash removal appts. comprises a body on which V-shaped two-arm levers are mounted around its periphery. A cutting tool holder is pivoted to one arm of each of the levers and cutting tools are rigidly attached to the holders. Drives, for turning the levers, are mounted on the body, each being connected with the other arm of each of the levers. On the front and rear ends of the cutting tool holders, there are mounted rollers in contact with the inner surface of the pipe. The appts. is useful in laying pipelines and in welding casing pipes. The cutting tool holders can be held in a withdrawn position during transport of the appts. thus facilitating movement of the appts. within the pipe. Abrasive wear of the rollers is insignificant compared with that of sliding supports so that any dangerous increase in cutting depth is excluded. Hence, the period between repairs of the appts. is increased, power- consumption for moving the appts. within pipes is reduced, and damage to the pipe walls and weld during flash removal is excluded.

Patent DE-3122725-A1 (DE)
Title: Supporting frame for holding a mobile working machine for installation on a chassis
Inventor: FENZL FRANZ ING GRAD
IPC: B66C23/78
Filed: 1981-06-06
Abstract: The use of the supporting frame is preferably provided for a concrete pump with a dispersal pole, which is installed on a lorry chassis. The main feature of this supporting frame consists in the fact that the connection from the substructure of the rotary column to the rear support takes place by means of two connecting members which, as was previously customary, are not connected over the entire length of the longitudinal members of the lorry chassis but rather extend backwards, free from the substructure of the rotary column, as far as the greatest admissible vehicle width (2.50 m). As a result, the following advantages are obtained:   a) the locally induced operating forces of the rear support are substantially smaller than in designs with connecting members which extend at a small distance (approximately 0.90 m) from one another on the longitudinal members of the lorry chassis (U-profiles), b) the longitudinal members of the lorry chassis are thus no longer loaded by operational forces of the support and, with the auxiliary frame which also consists of U-profiles, can remain easily rotatable over almost their entire length, which is a design aim in lorries; c) all the substructures can be attached to the connecting members or to the supporting bar of the rear support and thus do not restrict the freedom of movement of the longitudinal members of the lorry chassis; d) the connecting members can be used as containers for holding fluids; e) the entire structure can be completely premounted in a vehicle-independent manner.   <IMAGE>
