Title: Hydrochloric acid pickling soln. regeneration with cold sulphuric acid - giving ferrous sulphate hepta:hydrate as useful by=product
Inventor: CZARNOWSKI GOTTFRIED VON
IPC: C23G1/36
Filed: 1991-07-11
Abstract: In the regeneration of pickling solns. contg. HCl by adding conc. H2SO4, the soln. is kept at a temp. below 45 deg. C. Reaction between H2SO4 and Fe chloride is carried out in vacuo. Cold centrifuge filtrate contg. H2SO4 is pref. used as cooling medium. USE/ADVANTAGE - The process is esp. used for regenerating solns. used for pickling steel strip. All the FeCl2 present is converted to FeSO4.7H2O, which is readily soluble and can be used for various purposes, e.g. H2SO4 recovery, dyestuff prodn. or water treatment. In contrast, regeneration with conc. H2SO4 at over 50 deg.C gives FeSO4.H2O, which is insoluble in water and cannot be recovered economically, whilst roasting gives Fe2O3 and entails a high energy consumption.

Title: Video signal filter circuit for transformed and quantised data blocks - uses two=dimensional block coordinates with relative coordinates or transformation coefficients with two=dimensional variables
Inventor: BADIQUE ERIC DR
IPC: H04N19/86
Filed: 1991-08-31
Abstract: The circuit filters a video signal represented by sampled values of pixels (I(q,x)) whose geometrical location in a video picture are determined by two-dimensional block coordinates (q) and relative coordinates (x). Alternatively, the signal is represented by transformation coefficients (C(q,u)), u being a two-dimensional variable in the transformation domain. A filtered signal is determined for which the value of the function F is at a minimum, where: F = Sum(x,q) (IS(q,x)-I(q,x))power2 + mu.Sum(q,x) (IS(q,x) - IP(q,x))power2 and the difference between the transformation coefficient (CS(q,u)) for the filtered video signal and that (C(q,u)) for the video signal (I(q,x)) is below a threshold D(q,u). Mu is an experimental parameter. The sum in  the second term of the function F uses values of x which belong to the set of edge points (Rq) of the block having the block coordinates q. IP(q,x) is a target boundary value for the boundary point x of the block. The target value is determined from an average value of the filtered video signal, derived from the sampled pixel values which lie adjacent to the block having the coordinates q. ADVANTAGE - Block structure is almost completely suppressed and compression is assisted.
