Abstract: The invention relates to a method for regenerating by crystallization on cooling picking bath solutions based on sulphuric acid or hydrochloric acid and used for pickling iron, steel and other iron alloys. According to the invention the bath solution is regenerated in a combination of three stages. In a first stage acid is added to the solution in a concentration higher than the acid concentration of said solution, and the content of phosphoric acid is adjusted to be maintained between about 0.01 and 1 mole per litre solution, thereby to approach or to exceed the solubility of difficultly dissolved iron salts corresponding to the acid. In a second stage the solution is cooled, whereby iron salts precipitate. The cooling process is effected so as to reach a temperature at which the contents of iron and acid in the residual solution are suitable to permit said solution to be used again for pickling purposes. In a third stage the precipitated iron salt is removed from the solution, whereafter the regenerated pickling solution is returned for use at the pickling process.

Abstract: In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.

Title: Enhanced-resolution, multiply-exposed reflection hologram
Inventor: SMITH RONALD T
IPC: G02B5/32
Filed: 1990-07-26
Granted: 1995-08-01
Abstract: A recording medium has a first fringe pattern which is described by a first spectral bandwidth and a first image blur factor.  The recording medium also has a second fringe pattern which is described by a second spectral bandwidth and a second image blur factor, the first spectral bandwidth being different from the second spectral bandwidth, and the first image blur factor being substantially equal to the second image blur factor.  By providing multiple holograms in the single recording medium, the spectral bandwidths of each hologram are combined to provide an overall spectral bandwidth.  Since the image blur factors of each hologram are substantially the same, i.e., overlap, when the two holograms are combined, the overall image blur factor is not increased. Indeed, it decreases at the same time the thickness of the recording medium is increased by a factor which is equivalent to the number of exposures in the single recording medium.  The result is increased bandwidth without a concomitant increase in image blur.
