Abstract: In a process for improving the sliding of alternating pistons of thermal engines while counteracting the tilting movement of said pistons, a pressure gradient is generated by the action of vibrating elastic means (1, 1a) resistant to the thermal and chemical stresses produced by the explosion, and by the usual infiltration of the driving gases into the piston groove, said means being mounted behind the piston ring. The pressure gradient results in the formation of a permanent pressurized toric seal during operation of the engine.

Abstract: The invention relates to a method and a device for the disposal and utilization of all sorts of waste materials such as the disposal of industrial, domestic or special waste and related industrial products which have become waste products. The invention also relates especially to the elimination and utilization of gases which are absorbed by cooling water during the rapid cooling of a raw synthesis gas and are released into an area where they are allowed to settle. The waste material which is to be disposed of forms a gas-permeable aggregate (20) in a high-temperature area, wherein a raw synthesis gas is produced. The raw synthesis gas is rapidly cooled, in order to prevent new harmful substances from forming, by spraying cold water, whereupon it is cleansed and the cold water subsequently purified in the sedimentation basin (103). According to the invention, the gases which are released from the cold water in the sedimentation basin (103) are reintroduced into the material cycle or are transformed by heat.

Abstract: The invention relates to a connection system for the repeated firm connection of two structural parts (1, 2) in an arrangement coaxial relative to a main axis (3). The one structural part (1) can be temporarily elastically deformed during the connection process so that an effective peripheral contour (10) about the main axis (3) of the one structural part (1) corresponds to an effective peripheral contour (5) about the main axis (3) of the other structural part (2), the two parts having a predetermined clearance relative to each other. Once the two parts (1, 2) have been coaxially arranged the one structural part (1) elastically returns at least partially to its original shape, thereby giving a firm pressure connection of the two effective peripheral contours (5, 10). To this end, the deformable structural part (1) is provided with a base element (6), a termination element (9) and at least one arching element (7, 8), every arching element (7, 8) forming a part of the effective peripheral contour (10) of the one structural part (1). Said arching element (7, 8) form an integral part with the base element (6) and extend along the main axis (3) from the base element (6) across the effective peripheral contour (10) to the termination element (9). When the one structural part (1) is deformed, every arching element (7, 8) elastically arches.

Abstract: The method serves for drying an active part containing at least one winding and solid insulations. The active part is arranged in a vacuum-tight housing and is heated there to a final temperature value (Tfin) by means of warmed oil and by means of a current (I) carried in the winding. The warmed oil is sprayed in the housing at reduced pressure (p) and with the current (I) switched on. At the same time, water is extracted from the active part. The sprayed oil is collected on the housing bottom, after discharging heat to the active part, and, after rewarming, is sprayed once again in the housing at reduced pressure and with the current switched on. The active part is thus dried particularly quickly and carefully.

Abstract: A device for connecting two tool parts having a common axis. The device includes a fitting pin projecting axially from the first tool part and a connecting sleeve projecting from the second tool part and having a mating bore for receiving the fitting pin. A tightening mechanism equipped with a tightening bolt movable in a crossbore of the fitting point assures a sufficient planar surface to planar surface tightening between the two tool parts. Aside from the tightening in direction of the tightening bolt, a clamping of the fitting pin into the mating bore of the connecting sleeve is achieved through suitable measures, the clamping extending transversely with respect to the tightening-bolt direction and resulting in an automatic centering of the tool parts with respect to their common axis and in a reinforcement of the connection transversely with respect to the tightening-bolt axis.

Abstract: The proposed process makes it possible to determine the diffusion coefficient (D) from the pressures (p1?, p2?) and temperatures (T1?, T2?) measured in two chambers (1, 2) mutually separated by an elastic diaphragm by iteratively solving an equation representing the Flick's second law and initially solved with an assumed value for the diffusion coefficient using (D) until the calculated concentration c2? in the second chamber (2) agrees with the value determined from the measured pressures and temperatures. It is also possible to obtain the permeation coefficient (Q) by using the ambient temperature (TO?) and pressure (pO?). The values found are plotted on a graph which makes it possible to see when the experiment has entered a stationary state and the value then found may be regarded as the final one. The proposed device for implementing the process has a computing device (8) for making the necessary calculations in real time. The device remains closed during the experiment, thus facilitating operations with hazardous gases. There is no need for the difficult measurement of small volume currents. Thus the measuring process of the invention has distinct advantages with respect to measuring time and accuracy.
