Title: Hollow section forming for generator cooling elements - uses plugs through-channel blocks with subsequent calibrating and stretching
Inventor: NIEWIERA WOLFGANG DIPL ING
IPC: B21C37/06
Filed: 1979-10-02
Abstract: The finished cooling element for generators consists of a strip of copper, or copper alloy with longitudinal circular section channels and with a solid section without channels in the middle element. To arrive at the final design of the element, a copper block with three channels (2,3,4) is rolled or drawn. At this stage the channels are considerably larger than the required final size. The block is then repeatedly calibrated until channel sizes slightly larger than the final size is reached. Subsequently plugs (5,6,7) are introduced into the channels (2,3,4) and positioned in the middle of the block length. The open ends of the channels are closed up by mandrels (9,10,11) and the block is stretched until the channels (2,3,4) reach a tight fit with the plugs (5,6,7) which now form the solid section in the middle of the finished strip required for fixing the cooling element on the generator. In a final operation the mandrels (9,10,11) are removed from the block ends.
Patent DE-2947414-A1 (DE)
Inventor: NEBHUTH KARL-HEINZ
IPC: G01G11/00
Filed: 1979-11-24
Abstract: In the case of a measuring device having a guiding device with an outlet opposite a measuring surface (baffle plate) which deflects a stream of bulk material and detects horizontal force components, the frictional forces on the measuring surface and the impact shock of the stream of bulk material striking the measuring surface need to be kept low. This is achieved in that the guiding device is composed of a guide chute (6) to which the free-falling bulk material (4) can be fed, furthermore that the guide chute (6) is steeply inclined in its upper part and less steeply inclined in its lower part, so that it receives the stream (4) of bulk material with as little impact shock as possible and deflects it obliquely downwards to the measuring surface (1, 9) and that the measuring surface (1, 9) is essentially arranged in a vertical plane, so that the stream (4) of bulk material coming from the guide chute (6) strikes the said measuring surface (1, 9) at an acute angle. An arrangement of this type eliminates friction and impact shocks on the measuring surface to a substantial extent, so that such effects do not influence the measuring result. <IMAGE>
