Title: Process for improving dynamic and static characteristic values in the case of reinforced-concrete floors
Inventor: KARSTEN R PROF DR ING
IPC: E04G23/02
Filed: 1989-01-27
Abstract: The invention presents a process for improving the dynamic and the static characteristic values of an in-situ-concrete structure in a particularly and surprisingly effective manner. This process is characterised in that any reinforced-concrete cross-sections present are reinforced on the bottom side by steel sections which, by means of steel butt straps arranged on the top side, achieve a tension-resistant connection, whereupon a reinforced concrete layer is applied on the top side, indeed - e.g. by means of a suitable bonding course - in a shear-resistant bond with the existing reinforced-concrete structure, e.g. a reinforced-concrete floor. The screw heads serve as dowelling between the top concrete layer and the original reinforced-concrete structure. By virtue of the combined friction and adhesive bond achieved in this manner, the dynamic and static characteristic values, for example, of a reinforced-concrete floor are, as explained, surprisingly effectively improved, and, for example, disruptive vibrations which are caused by the use of a, for example, small-dimension intermediate floor of a building can be reduced to a reasonable degree in a simple and cost-effective manner.

Title: Process and arrangement for fastening flexible tubes
Inventor: ALEXANDRE MICHEL
IPC: F16L33/08
Filed: 1989-03-04
Abstract: The invention relates to a process and to an arrangement for fastening the end of a flexible hose (5) on a tubular counterpart (6). Located on the flexible hose (5), close to the end thereof, is a tightenable clamping ring (10) which can be tightened by means of an actuating element (24) after the hose (5) has been plugged onto the tubular counterpart (6), this resulting in a fluid-tight through-passage channel. According to the invention, before the parts are fitted together, the clamping ring (10) is introduced into the channel-shaped part of a sleeve-shaped housing (12) which, for its part, is fastened on the outer surface of the hose (5), for example by adhesive bonding. The clamping ring (10) introduced into the housing (12) projects, by means of its actuating element (24), out of an opening (22) in the channel-like part (20), with the result that the actuating element (24) is freely accessible and, at the same time, definite fixing of the position of the clamping ring (10) with respect to the hose (5) is ensured. <IMAGE>
