Title: Pressure resistance welding pipes on radiators - using internal support inside radiator behind the joint
IPC: B23K11/00
Filed: 1973-04-09
Abstract: The welding of pipe-fittings onto hollow containers, esp. radiators, where a small projection or bead is provided on the ends of the pipe and a support is provided inside the container so that press. can be used during the welding operation. In welding e.g. a T-piece between two radiators, the assembly is located in a horizontal press between the electrodes. In each hollow tank is a support stool which extends across the entire section so that there is a metal path between the electrodes and the joints. The stools have concentric holes to match the pipes, but they support the metal round the holes. The small ring-projection on the pipe ends provides the necessary electrical resistance so that a good joint can be made. The process eliminates hand-welding.

Patent DE-2419954-A1 (DE)
Title: Appts for raising-lowering maintenance cradle - using two separate nylon rope systems, and block-and-tackle device
Inventor: SCHULLER HERI DIPL-ING
IPC: A62B1/14
Filed: 1974-04-25
Abstract: Appts. for raising and lowering maintenance cradles, esp. for inspecting, repairing and cleaning walls of high buildings, has two separate nylon rope systems for suspending and moving the carrier. One rope acts as safety rope during the raising of the carrier, and also serves to lower the carrier, this rope passing partly round a stationary brake drum so that its movement can be braked continuously by a disc brake. A rop locking device allows the rope to pass when in the open posn. Another rope passing over a fixed pulley raises the carrier, and is engaged at one end with a block-and-tackle. During the raising movement and also during pauses, the rope and the cords of the block-and-tackle are secured against return movement by rope clamping devices; and during the raising pauses are laid over supports. In the addn., during the lowering of the carrier the second rope is braked by passing partly round another brake drum, and is allowed to run downwards by holding open a rope clamping device placed immediately after the brake drum, the second rope being retainable in this device so that this rope acts as a security rope for the first rope during the lowering operation. For low working heights (below 40 m) the second rope is released, and the carrier is raised exclusively by the block-and-tackle, which is fastened to the building and extends to the ground. In the latter case the draw rope of the block-and-tackle acts as security rope during the lowering of the carrier, while this rope is allowed to retain its posn. on the base plate, and released from its clamping devices. The draw rope is wound once around the foot of the support and guided by the right hand during the lowering operation, or is shifted before use so that it runs through the eyelet of the base plate and assumes the posn. of the second rope, thus also acting as security rope during the lowering of the carrier. The disc brake of the first rope is mounted between the locking device and the brake drum at the plane of the rope running on the brake drum during lowering, and a support is provided outside the locking device for the lowering rope end. The second rope acts as security rope during the lowering of the carrier from great heights (over 40 m). For lower heights (below 40 m) the block-and-tackle acts as security rope. This arrangement facilitates operation of the appts., and improves security during operation.
