Title: Barrier for outgoing liquids
Inventor: WOHLER HANS
IPC: G01G7/02
Filed: 1989-02-16
Abstract: The barrier serves to protect the environment against outgoing liquids. It comprises a collapsible hose which, when not in use, is located in a hollow and is covered by pivoting covers which run flush with respect to the ground. In the event of danger, the hose is filled with water.

Title: Precious metal dissolution and pptn. - using molten alkali metal hydroxide and oxide with alkali metal addn.
IPC: C22B11/02
Filed: 1990-01-21
Abstract: Dissolution and pptn. of gold and other precious metals are carried out by introducing precious metal-contg. substances into a melt of alkali metal hydroxide and alkali metal oxide, in the absence of oxygen and nitrogen, and dissolving an alkali metal in the melt so that electrons are transferred from the alkali metal to the precious metals to form mobile negative ions. Pptn. of the precious metals from the melt is effected by introducing oxygen or nitrogen into the melt to strip the transferred electrons from the negative precious metal ions. USE/ADVANTAGE - The process is useful for recovery of gold and other precious metals from nature gold, circuit board coatings and contacts. It avoids the use of toxic solvents and the solidified melt is converted e.g. in air, to soda which can be disposed of without causing pollution.

Patent DE-4006983-A1 (DE)
Inventor: SCHNEIDER WILFRIED
IPC: E06B3/62
Filed: 1990-03-06
Abstract: A sealing profile, in particular for sealing between a window frame and the associated window pane, comprises a compound profile cross-section with different wall thicknesses, the sealing profile in the longitudinal direction having one or more through-cavities. To ensure reliable and permanent sealing against moisture and heat loss, at least one cavity of the sealing profile is filled with a filler material. Furthermore, the wall of the filled cavity facing the area to be sealed is made thin in relation to the other wall thicknesses. After the window pane has been fitted, the cavity thus tears open and the filler material can emerge for sealing purposes. In the method for producing such a sealing profile by extruding, at least one cavity is formed before the sealing profile emerges from the die and then, directly after the cavity has been formed, filler material is introduced into the cavity in the emergence region. <IMAGE>
