Abstract: The invention relates to a hyperfiltration membrane containing a supporting layer and a separation layer. The membrane is characterized in that the separation layer consists of a crosslinked monomolecular film of molecules, the molecules of the separation layer in the uncrosslinked state being surfactants or surfactant-like lipoids containing at least one hydrophobic chain and at least one hydrophilic group, the hydrophobic chains of these molecules being oriented mainly perpendicularly to the plan of the membrane and parallel to the diffusion direction after crosslinking and the molecules of the separation layer being crosslinked with one another through functional groups in at least one of their hydrophobic chains and/or through functional groups in at least one of their hydrophilic groups.

Abstract: An air weapon comprising a hand grip and a generally tubular-shaped housing connected thereto having front and rear ends confining a tubular pressure chamber. The pressure chamber is of non-cylindrical configuration thereby providing a pressure chamber of increased volume over that obtainable with a cylindrically shaped chamber without detrimentally affecting the external appearance of the weapon. A cylindrical barrel for discharging a projectile from the weapon is positioned within and coaxial to the pressure chamber. A piston conforming to the configuration of the pressure chamber and adapted to move within the pressure chamber along its axis surrounds the barrel with its piston head facing the rear end of the housing. A piston spring also surrounds the barrel and is positioned against the piston head at one of its ends and against the front end of the housing at its other end.
Abstract: The working fluid for traction drive use has a particularly high traction coefficient at high temperatures and the principal ingredient thereof is a decahydronaphthalene compound substituted, on either one or both of the decahydronaphthalene rings, with two or three substituent groups which may be cyclohexyl groups, cyclohexyl alkyl groups, e.g. cyclohexyl methyl, cyclohexyl ethyl, 1-methyl-1-cyclohexyl ethyl and 1-methyl-1-(methylcyclohexyl) ethyl groups, or a combination thereof. The working fluid can be a mixture of a base oil of various types and the above mentioned decahydronaphthalene compound in an amount of 5 to 250 parts by weight per 100 parts by weight of the base oil.
