Exemplary ion scavenger compounds include ##STR1## the tetraethyl acetate of 7, 13, 19, 25-tetra-tertbutyl-27, 28, 29, 30-tetrahydroxy-2,3-dihomo-3-oxacalix-4-arene and 1,1-dimethasila-17-crown-6.

Abstract: Novel nitrogen-containing calixarene derivatives which are useful for sequestration of transition metals are represented by the formulae ##STR1## wherein m+n=4,6 or 8n=an integer 1-8m=an integer 0-7x=4, 6 or 8R.sup.1 is H, alkyl, aralkyl, alkoxy, aroyl, or alkoyl,R is aliphatic or aromatic, unsubstituted or substituted hydrocarbyl containing nitrogen,R.sup.4 is unsubstituted or substituted hydrocarbyl, carbonyl or aryl;R.sup.5 and R.sup.6 (which may be the same or different) are hydrogen, or unsubstituted or substituted hydrocarbyl.A process for separating transition metals from mixtures containing such metals comprises treating such a mixture with a calixarene derivative of formula I or II as defined above and separating therefrom a complex of the calixarene derivative and the transition metal. The complex may then be broken down, the transition metal recovered and the calixarene derivative recycled for further use in the process.

Abstract: The screen of a display terminal has touch strips extending adjacent horizontal and vertical edges. The touch strips have electrical outputs dependent on the position along the strips at which they are touched. Using microprocessor control the touch strips can be made to manipulate a displayed image and control the rate or level or other terminal functions. By selecting an appropriate programming mode the touch strips can be made to present a series of programmable or soft keys. Also the touch strips can be used to provide a menu selection, scrolling and cursor generation and movement for word processing. The use of two touch strips requires less complex circuitry than a known transparent input overlay for the display screen. Moreover, it is a cleaner technique resulting in reduced image attenuation and distortion.
