Title: Flexible elastomer pipe joint - with flanged ends reinforced by elastomer layer containing chopped fibre strands
Inventor: POHLMANN KLAUS DIPL ING
IPC: F16L33/28
Filed: 1979-01-13
Abstract: Flexible pipe joint consists of an elastomer tube with reinforcing plies, shaped in a central bulge with two flanges at the ends. These flanges are bolted to the flanges of the adjoining metal pipe lengths with a metal backing ring. At the face towards the metal pipe flange, the flange of the flexible pipe joint receives a layer of an elastomer material with reinforcing fibres in a random dispersion.

Title: Pig swill mixing tank - with circulation pump and dry fodder ingestion impeller
Inventor: LANZINGER JOSEF
IPC: A23N17/00
Filed: 1979-01-24
Abstract: Pig swill is prepared in a tank in which an immersed pump on a central shaft effects a circulation.
