Abstract: An efficient method for the highly selective recovery of silver value in an aqueous solution containing silver ions in a low concentration, such as depleted photographic fixing solutions, comprises extracting the silver ions from the aqueous phase with an organic solution containing 0,0-bis(2-ethylhexyl) hydrogen thiophosphate as an extractant solution, the silver ions contained in the extract solution being back-extracted with a hydrochloric acid solution containing thiourea. Alternatively, the silver-containing starting aqueous solution may be contacted with beads of a porous resin bearing the thiophosphate compound so that the silver ions are selectively adsorbed on the resin beads and then the silver ions are leached out of the resin beads with an organic solvent.

Abstract: An alloy of nickel and titanium in the atomic ratio of 49:51 to 56:44 can be prepared at a temperature much lower than the eutectic point of the corresponding alloy. Thus, a green compact of a powdery mixture of the component metals is subjected to a heat treatment under high vacuum first at a rate of temperature increase of 5 to 30 °C per minute up to a temperature of, for example, 600 °C and then at a rate of temperature increase of at least 40 °C per minute up to a temperature of 815-900 °C. The surface of the metal particles is activated during the first stage together with degassing and the surface-activated metal particles are brought into an exothermic reaction at the second stage to cause explosive fusion and alloying.

Abstract: When preparing carbon fibers from mesophase pitches, are usually encounters the formation of cracks along the fiber axis. The crack formation is the most serious and troublesome problem. A simple process and apparatus which can effectively prevent the crack formation are disclosed. The process is that when preparing the carbon fibers from mesophase pitches by melt spinning, it is sufficient only to give a rotatory motion to the molten mesophase pitches just before extrusion substantially around the axis of a spinning nozzle hole (3). The apparatus is essentially the same as a usual nozzle plate (1) having a pitch introducing tube (4) and a spinning nozzle hole (3) provided that the apparatus further contains a plug member (2) having an outer spiral groove (7) such as a drill point or a worm gear and the plug member (2) is inserted into the pitch introducing tube (4).
