Title: Safety device for a vulcanisation system for retreading tyres
Inventor: MARTIN FRIEDRICH
IPC: B29D30/56
Filed: 1982-05-19
Abstract: A safety device for a vulcanisation system for retreading tyres which are introduced into an autoclave under elevated pressure. To ensure that, in the case of pressure releases in the event of faults, the internal tyre pressure automatically follows the internal pressure of the autoclave with a predetermined, approximate pressure difference, each tyre has an additional valve which is designed such that, in the normal state, it simultaneously has a free passage opening for the unrestricted admission and discharge of the tyre internal pressure.

Patent DE-3309448-A1 (DE)
Inventor: THOMA MARTIN DR RER NAT
IPC: G01N33/20
Filed: 1983-03-16
Abstract: Titanium alloy test samples including welded samples of such alloys are tested for recognizing textural or structural faults or flaws in the form of segregations or liquations. To make these flaws visible by increasing the contrast between a flaw and the background, an etching method including two etching steps is used, which achieves especially marked contrasts. The method is based on the selective solution removal of a phase, a grain, or of an impurity of an alloy type. An especially good visual recognition of segregations, liquations or inhomogeneities of welded test samples is made possible by the resulting matte gray surface against which lustrous flaws are clearly visible.

Title: Radial impeller for flow machines
Inventor: KOLLER ALOIS DR
IPC: F04D29/22
Filed: 1983-09-12
Abstract: In a radial impeller (L2) equipped with a plurality of radial vanes (R2), the thickness of the vanes, measured along the circumference, increases outwards in such a way that the vane channels (S2) delimited by the radial vanes (R2) are designed either with parallel walls or narrow in an outward direction. Compared to the radial impellers used hitherto having vane channels which widen in an outwards direction, virtually vortex-free flow (1') is achieved in the vane channels (S2) with parallel walls or which narrow in an outward direction. Radial impellers (L2) of this type can be used for centrifugal pumps, centrifugal compressors or for drives based on the recoil principle. In radial pumps used for moving heated liquids or mixtures of liquids and gases, the vortex-free flow is particularly advantageous. <IMAGE>

Title: Exothermic transparent body
Inventor: ITOH TOSHIYASU
IPC: B60S1/02
Filed: 1984-05-18
Abstract: An exothermic transparent body, for example a window pane, a windscreen or the like, contains an electrically conductive transparent film layer which is formed uniformly on at least one surface of a transparent substrate of the body. At least one pair of metal electrodes are located on the electrically conductive film layer, along the two opposite sides of the layer. With their aid, electrical power is supplied into the electrically conductive transparent film layer, so that the surface of the exothermic transparent body is heated. In consequence, it is possible to prevent a reduction in the surface temperature of the body and consequently condensation on the surface of the body. This ensures that the surface of the body is free of streaks and the like. An excellent anti-condensation effect is achieved.
