  • System for sealing a pipeline system
    Patent number: 9145998
    Abstract: A system is provided that includes a fluid-tight tube, which for insertion can be introduced into the area of a gap to be sealed between two pipes of the pipeline system to be sealed. The tube is provided with a feed element for introducing a fluid, with whose aid the tube is filled and thereby increased in its volume. The feed element contains a valve, which facilitates the introduction of the fluid and at the same time prevents the outward flow via the feed element.

  • Method of making a casting powder
    Patent number: 4127407
    Abstract: A casting powder which consists of lime, alumina and silicates (or silica), with or without alkali-metal compounds serving as fluxing agents, is made by expanding the particles from a particle size of less than 40 microns to a particle size in excess of 60 microns so that the particles are generally in the form of hollow bodies. The casting particles thus have a highly insulating character and are above the dust limit so as to reduce their environmental hazard.
