Abstract: An electromagnet device has a pair of electromagnets (10a, 10b) and a movable body (13, 13a, 16) movable by alternately switching the electromagnetic forces thereof. A controller (20, 21) for the device has a drive circuit (20) with switches (QL1, QL2, QR1, QR2) controlled by control means (21) which receives a command signal which initiates displacement of the body and current reference values. Comparators (CM1, CM2) compare these reference values with currents flowing throughthe coils (SR, SL) of the electromagnets. The control means (21) functions to cause the drive circuit (20) to supply current to both coils (SR, SL) of the electromagnets to maintain the movable body in an electromagnetically held state. When a first of the coils (SR) is in a state of holding the movable body the control means causes a current (IH) to be supplied to the first coil (SR) to maintain the holding state and causes a pre-energising current (IE) to be supplied to the second coil (SL). When the command signal signifies the body is to be displaced the holding current in the first coil (SR) maintaining the holding state is suddenly reduced.

Abstract: A gas-liquid reactor (100, 300) comprising an outside containment vessel (102,302) and an inside reaction vessel rotatably supported within the outside containment vessel (104, 304). A liquid is conducted into the inside reaction vessel (104, 304), and that vessel (104, 304) is rotated to force the liquid therein against a wall of the reaction vessel (104, 304) and into a film having a stable and geometrically simple shape. A gas is also conducted into the inside reaction vessel (104, 304) to react with the liquid therein. Because of the stable and simple shape of the liquid, the reactions between the liquid and gases are relatively easy to analyze mathematically.

Abstract: The invention has composition of matter and process aspects. The composition of matter aspect relates to compounds selected from the class consisting of

     The process aspect involves the use of these compounds to complex with and separate a desired selected ion from a multiple ion solution, breaking the complex to free the desired ion and recovering the freed desired ion. This process can be carried out in these ways: (A) as ligands in a liquid membrane phase for selectively and competitively separating desired metal ions from mixtures with other ions in a separate source phase and transporting these ions to a separate receiving phase, with both of which the liquid membrane phase is in interfacial contact long enough to effect substantial removal of the desired ions from the source phase and transporting them to the receiving phase from which they are recovered, (B) as covalently bonded to silica gel supported in a column through which the multiple ion solution is first flowed, followed by receiving liquid, and (C)   as ligand in an organic liquid filling pores or apertures in the wall of a hollow fiber in a bundle of hollow fibers on opposite sides of which flow the multiple ion solution and the receiving liquid.
