Title: Process for recovering sulphuric acid from waste acid liquors
IPC: F23N5/00
Filed: 1958-05-02
Abstract: The molar ratio <FORM:0880359/III/1> of a waste sulphuric acid liquor, e.g. the liquor remaining after the acid digestion of titaniferous ores and precipitation and removal of titanium hydrate therefrom, is adjusted to 0,8-1,25, preferably 1,1-1,2, for the purpose of producing a substantially pure concentrated acid, e.g. of a concentration of at least 80% by a process comprising the steps of adding a compound having a monovalent alum-forming cation, and cooling to a temperature sufficient to effect crystallization. The degree of cooling is preferably sufficient of itself to produce the desired ratio.  Such temperatures are -41- -47 DEG C. and -26- -32 DEG C. for waste acid concentrations of 18 and 26% H2SO4 respectively.  If insufficient cooling is employed to produce the desired ratio, the ratio may be adjusted by the addition of titanium sulphate.  After cooling the precipitate is removed, the remaining solution concentrated and aged, e.g. at 50-100 DEG C., to produce a further precipitate, and the further precipitate removed.  The waste acid preferably has a sulphuric acid concentration of 18-26%.  The acid concentration may be increased by the addition of concentrated product acid, or 60-65% acid obtained by washing solid removed from the concentrated acid with solution from the alum-producing step. Alum-forming compounds specified are ammonium hydroxide, carbonate, acetate, chloride, and sulphate, and potassium hydroxide, carbonate, and chloride.  Specification 800,052 is referred to.

Filed: 1917-10-03
Abstract: 110,746. Borel, J. L. A., and Grange (nÚe Borel), E. M. J. Oct. 24, 1916, [Convention date]. Fastenings. - Consists of a machine for inserting the springs into press-buttons and securing them by curlmg over the edge of the button. The spring c, Fig. 2, is placed by hand or automatically on a flat punch b having a reduced end b<2> in which is cut a notch b<3> to receive the dome d' of the button. The button d having the dome with the slots to receive the spring already formed, is placed by hand or automatically against the end of a punch l, and is retained by exhausting the passage l<1> through a pipe n controlled by a valve u, Fig. 1, actuated by a cam 9. In effecting this attachment of the button, the punch l is pushed to the right against a spring s' and retained in that position by a catch q. The slide a, carrying the punch b and other parts is now moved to the right by a cam 3 until the end of the punch b rests against the button. Further movement of the slide a causes the sleeve h surrounding the punch b to push the spring along the punch b and, as the spring enters the sleeve o, the ends are bent inwards to pass into the button. On the completion of the movement, the stop h' on the sleeve h strikes the stop b<4> on the punch b and the sleeve and punch continue to move together, pushing the punch l into the position shown in Fig. 3, the spring i being stronger than the spring s<1>. When the punch l strikes the stop m<1>, its movement is arrested but the outer sleeve e still moves on pushing back the sleeve o against its spring p and finally the die-end e<1> of the sleeve curls the edge of the button over the spring. The movement of the elide a under the action of the cam 3 now ceases, and the spring p pushes back the sleeve o, the cam r withdraws the catch q, the cam v, acting on the lever s, returns the punch l flush with the sleeve o and the cam 9 actuates the valve u to admit compressed air to eject the finished button.
