Title: Rotary piston engine with disc shaped power cylinder - rotor mounted in cylinder is rotated by medium flowing through cylinder
Inventor: PILZ FRANZ
IPC: F01D1/34
Filed: 1975-05-16
Abstract: The power cylinder (2) is in the shape of a disc, the circumference of which is widened into a ring shaped section. The rotor is mounted on a shaft and has enlarged circular end sections which fit in the ring shaped section of the cylinder. In plan view, the outline shape of the rotor is formed by two arcs (7, 8) which are offset from the centreline. The edges of the arcs are joined by radial sections (6). These radial sections are the part which run in the ring shaped part of the cylinder. A tangentional inlet flow from an inlet (5) impinges on these radial sections and drives the rotor round until the outlet gasses reach the outlet channel (4) which is located quite close to the inlet pipe.

Title: Rhythmic staged prestressed concrete bridge forwarding - using stress members periodically providing eccentric stresses for alternating moment absorption
Inventor: BONATZ PETER PROF DIPL ING DR
IPC: E04C5/08
Filed: 1977-01-31
Abstract: Erection of prestressed concrete bridges, involves making sections in a nearby fixed formwork and forwarding them in a rhythmic sequence, each new one being joined to its predecessor by prestressed connecting reinforcement rods, so as to provide continuous central or constantly eccentric stressing. During forwarding, provision is made for absorption of alternating moments at one or both edges by stress members (7, 8) with lengthways interrupted prestressing forces passed through them. These are repeatedly relaxed, withdrawn and re-stretched, acting against the forwarding direction, so that counteracting, temporary and eccentric prestressing forces are always present in the interval when they are needed. This is much less expensive than use of temporary auxiliary piers.
