Title: Stationary seal ring assembly for dry gas face seal unit - has support and retaining rings cooperating with shroud to urge seals against stationary ring
IPC: F04D29/08
Filed: 1991-03-15
Abstract: The assembly comprises a face seal ring (28) cooperating with a rotating mating ring (25) mounted on a rotating shaft (13). A shroud (21) is mounted on the periphery of the face seal ring (28) to prevent the ring from bending or deflecting when subjected to unbalanced gas pressures. A support ring (47) and a retaining ring (49) which together with the shroud, urge a pair of seals (55,57) against the opposite faces of the stationary face seal ring (28). The face seal ring (28) also includes a pair of concentric static annular grooves formed in the mating face of the seal ring (28), with radial recesses extending between the annular grooves. The high pressure gas is deflected against the radial and axial faces of the annular grooves to evenly distribute high pressure gas on the mating surface of the seal ring to tend to prevent deflection and bending of the stationary seal ring.

Title: A method a binder and a binding machine for closing hose or bag shaped packings primarily tubular foodstuff packings
Inventor: KROMAN FLEMMING
IPC: B65B51/04
Filed: 1987-05-29
Abstract: The closing of tubular casings containing foodstuffs by mounting a binder on a constriction of the casing involves the traditional problem of a high waste percentage due to the binders either damaging the casing material or sliding off the constriction. A method and a binder are proposed which makes it possible to obtain a very strong clamping of the binder without damaging the casing material, and, in connection with tight plastic casings, it is even possible to provide a "super tight" closure, by ranging the constriction with an oblong cross section between opposed straight clamping beams, which are forced together so as to produce a controlled deformation flowing of the casing material.
