Title: High speed band saw with low noise - for removing aligning beams from butt welded steel plates in shipbuilding
Inventor: ZIMMER ALBERT
IPC: B23D53/00
Filed: 1975-07-25
Abstract: Cut-off device, esp. for shipbuilding, employed to remove projecting holder beams which are tack-welded onto steel plates prior to welding the plates together. The beams are used to align the plates before the latter are welded. The novelty is the use of a band saw running over a driving wheel and two sets of adjustable rollers; the two sets of rollers form a half circle with a gap at its base between the sets, forming the cutting zone. The sets of rollers are pref. adjustable so the cutting gap can be varied. The device is pref. mounted on a trolley so it can be driven along and over the beams.

Title: Antidroop device for thin metal plate suspended ceiling - using inserted stiffeners with connections to plate bases to keep them flat
Inventor: SCHMITT HANS-JULIUS
IPC: E04B9/04
Filed: 1975-08-01
Abstract: The metal ceiling plates, or panels, have upturned edges (5) all round. At the centre of the plate base (2), and nowhere where else, there are devices (3, 6) for altering and stabilising the arching (9) of the base. The stabilising stiffener element (3) can be inserted in the plate so that the latter can be suitably connected to the plate base, using screws, rivets, weldings or other connections (6). Although it is not practicable to prevent downward drooping or sagging of thin plates altogether, a stabilised, moderate and regular sag is achieved by inexpensive means, with an enhanced, architectonic, aesthetic ambience.

Title: Nuclear vessel assembled from forged rings by welding - has support flange forged integrally with ring or tube-plate
Inventor: WIETELMANN FRIEDRICH ING GRAD
IPC: G21C13/024
Filed: 1976-09-21
Abstract: A support flange for a vessel, esp. the load-bearing flange of a pressure vessel in a nuclear power plant, is forged integrally with one of the rings or a tube plate of the vessel. Pref., the load-bearing flange is a continuous collar around the vessel and is of the same overall depth as the associated forged ring. Used in vessels built up by welding together forged rings, end plates or domes, and tube plates. By forging the flange integrally with the associated ring or tube plate, a load-bearing weld in this region is eliminated. It is thus possible to dispense with the need for regular ultrasonic inspection of this weld, which is normally in a particularly difficult area for access.
