This process is of the type in which there is compressed in at least two stages 2, 6 a mixture of cooling fluids composed of constituents of different volatilities and in which, after the last stage 6 and after at least an intermediate compression stage 2, the mixture is partly condensed, the condensed fractions are expanded and vaporized in heat exchange with the fluid to be cooled before being c...

A roll for use in the system of rolls of a calender has a stationary carrier which is surrounded by a deformable hollow cylindrical shell movable radially relative to the carrier and having end portions which surround and are rotatable relative to rings which are also movable relative to the carrier in the radial direction of the shell. The rings can be arrested in selected positions with referenc...

A process is described by which copper and optionally silver and gold are recovered from sulfide and oxide ores, concentrates or slag, which contain the metals. The particulate materials are treated with an aqueous solution of an alkali cyanide or alkaline earth cyanide, the laden solution is filtered, if desired, a water-soluble sulfide compound is added to the laden solution or filtered laden so...

The sucker rod system in a deep well sucker rod pump consists of a plurality of unidirectionally reinforced composite fiber rods extending substantially parallel but not in contact with each other, the cross-sectional area of which rods is less than 1 cm2. This enables the advantageous material properties to be utilized to a high degree. The sucker rod system can be assembled on site. The individu...
