Title: Reinforcement of joints in spherical GRP pressure vessels - esp. for beer reservoirs for assembly from twin shells on site
IPC: F16J12/00
Filed: 1977-08-11
Abstract: Spherical pressure vessels are assembled from twin hemispherical shells which butt together at their rims, where the joint is covered by an internal band and by an external bandage where the latter is made of layers of mat and of cloth impregnated with (polyester) resin and varying in width to decrease progressively in overall thickness from the level of the joint to the borders of the bandage. The inner most layer of the bandage is of mat 50-75% of the overall bandage width. The adjacent layer is of cloth 25-50% of the overall bandage width, with successive layers getting wider until the outermost layer, which is of cloth, is of the overall width of the bandage. Used for reservoirs for holding carbonated drinsk, esp. for spheres of approx. 1.25 m dia. to be assembled in hotel cellars for storing beer at working pressures 15 atm. The cloth layers enhance the hoop strength of the joint biaxially. The mat layers enhance the shear strength of the joint.

Title: Thyristor controlled power system - has compensation capacitor with choke on DC side of thyristor bridge circuit
Inventor: KNUTH DETLEF DIPL ING
IPC: H02J3/18
Filed: 1978-07-20
Abstract: By employing a bridge connected thyristor assembly (S) as the switch controlling the capacitor current the additional inductance necessary to limit transient and fault current can be placed on the d.c. side of the bridge. Here the choke (1d) has no detrimental effect on the degree of compensation achieved by the capacitors. The arrangement can also be used to control harmonic filters (F). The filters are tuned exactly to the required harmonic, the choke (Ld) on the DC side having very much less effect than a current limiting choke in the AC lines.

Filed: 1978-08-23
Abstract: In process for the separation of liquids from suspensions by means of at least one filter layer, on one side of which a suspension is fed and solids accumulate, and on the other side of which separated liquid is carried away, there is given an improved clearing of the feed side filter surface (ZFF) and thus a lengthened operation time until maintenance of the filter layer, through a flow movement (P1, P2) in the suspension chamber (SPR) with movement components oscillating in the normal direction in relation to the filter surface (ZFF), preferably through a suspension flow oscillating between filter surfaces (ZFF) lying opposite each other. An apparatus for the separation of liquids from suspensions makes possible such an improved operation through the suspension-drive device (AV1) with a plurality of surface elements (FE1, FE2) in the direction of movement and which can be flowed around transversely thereto (FIG. 5).
