Title: Automatic adaptation of roll frame rotations during rotational breakdown in one of the frames - with prior rolls compensating from breakdown, to prevent material build-up in front of problem roll frame
Inventor: DROEGE FRIEDRICH
IPC: B21B37/52
Filed: 1992-09-02
Abstract: When the roll rotation in a roll frame deviates from the optimum value, the optimum value is subtracted from the nominal value and then divided by the optimum value. This resultant percentage value is fed to a switch device which feeds this value back to previous roll frames to allow their rotational speeds to be compensated for during the time taken to return the problem roll frames to its optimum rotational speed. Each roll frame has its own switching device which feeds correction values back to previous roll frames, thereby making the correction process a constant process throughout the whole rolling mill. USE/ADVANTAGE - In steel wire and rod rolling. Optimises the correction process without the need for manual interference, thereby ensuring dimensional accuracy of the final product.

Title: Motor vehicle with an engine bonnet and/or boot lid
Inventor: KAHLE WOLFGANG
IPC: B60R21/34
Filed: 1993-04-27
Abstract: In accidents the windscreen and/or rear window form a vulnerable point of the vehicle. In particular when a passenger car collides with a lorry there is the risk of objects jutting out from the lorry or falling therefrom striking these windows and damaging them, or even penetrating and passing into the interior of the vehicle, thus resulting in a corresponding risk of injury for the occupants of the passenger car. The invention envisages the arrangement of at least one lever arm (1) for the engine bonnet and/or boot lid (3) of the vehicle. In the event of a vehicle impact these lever arms (1) cause that side (12) of the bonnet/lid which faces the window (9) to be raised under the action of the impact force. As a result, in the event of a strong impact the bonnet/lid (3) is positioned as a protective shield in front of the vehicle window (9) and hence prevents objects from striking the window (9). Use in the construction of motor vehicles. <IMAGE>

Title: Valve device for insertion in a hollow organ, a vessel or the like
Inventor: BERG GEORG DR
IPC: A61M25/04
Filed: 1993-05-21
Abstract: A valve device according to the invention is intended, in particular, as a substitute for a heart valve. For this case, it essentially comprises a heart valve anchorage ring and an artificial heart valve. The heart valve anchorage ring and the heart valve itself can be rolled together spirally up to an outer cross-section which permits insertion through a blood vessel to the heart. In the region of the heart valve to be replaced the anchorage ring can be widened and connected to the edge of the heart valve opening. The artificial heart valve can also be rolled up there and then movably connected to the anchorage ring. The artificial heart valve and/or the anchorage ring are preferably made of a so-called memory material which assumes its original shape under the influence of heat. In the present case, the original shape that is assumed under the influence of heat represents the functional shape of anchorage ring and artificial heart valve.

Title: Pipeline
Inventor: VAHLBRAUK KARL HEINZ
IPC: E03F3/04
Filed: 1993-09-24
Abstract: To simplify the making of pipe connections, to improve the resistance to environmental effects, in particular to chemical stresses caused by the medium flowing in the pipeline, to simplify adaptation measures with respect to different pressure loads and to simplify the provision of thermal insulation, a pipeline is proposed whose pipes consist of a geopolymer material, which if need be may be conditioned in a foamed (expanded) or else unfoamed (unexpanded) state, it being possible for a pipe connection to be established between two pipe ends (16, 17), one projecting over the other and arranged in alignment with each other, by the said ends being bonded to each other at the end faces by means of an adhesive layer (21) which consists of a, for example unfoamed, geopolymer material. This produces a pipeline which is completely homogeneous in terms of its material over the separating plane (18). For further securement with respect to axial pulling out, a sleeve (22) likewise consisting of a geopolymer material is proposed, said sleeve symmetrically covering over the separating plane (18) and the annular space (23) between the internally profiled sleeve (22) and the externally profiled pipe ends (16, 17) being filled with an adhesive, to be specific again a, for example unfoamed, geopolymer material.

Patent DE-4341030-A1 (DE)
Title: Starter switch for heater installation
Inventor: STRANGHOENER RALF
IPC: F24H9/00
Filed: 1993-12-02
Abstract: The heating installation is controlled by a programmable sequence switch which starts a heating cycle, following a fall in temperature, after a predetermined time, following the previous heating cycle. The switch is so programmed that cold water, at a temperature below the dew-point, is prevented from entering the heating circuit, where it can cause condensation. It is preferred to cause a time delay, established by trial, to enable the boiler water to reach a suitable temperature before circulation starts, than use of temperature control.
