Recovery of cesium, technetium, rhodium and palladium from stored waste supernates
The results of our assessment of the processing methods and costs for the recovery of cesium, techneium, rhodium, and palladium from aged waste supernates are presented. Guidelines for the assessment of costs are given. Cesium can be readily absorbed from alkaline waste supernates without prior treatment using Linde AW-500, a synthetic zolite. Technetium, present in the supernate as the pertechnetate anion, together with rhodium and palladium, probably present as anionic nitrite complexes, can be absorbed from untreated waste supernates using Dowex 1-X4 or similar anion resins. Although the behavior of cesium and technetium is reasonably well understood, the behavior of the anionic complex that accounts for the presence of rhodium and palladium in this strongly alkaline solution is not well understood. Further work is required before a process can be outlined for the clean separation of rhodium and palladium from the technetium-rhodium-palladium crude fraction sorbed on the anion resin. An assessment of capital and operating costs for the recovery of cesium only, technetium only, or both cesium and technetium are tabulated. No costs are shown for rhodium and palladium, since the technology for their separation is not sufficiently advanced. However, the incremental cost for their separation from technetium is expected …

Exact Semiclassical Calculations of Translational-Vibrational Energy Transfer
We present "exact" calculations, by the semiclassical method, of vibrational excitation of a harmonic diatomic molecule A-B, in its ground vibrational state, upon collinear collision with an atom C. Results are compared with those of first-order quantum mechanical time dependent perturbation methods and those of purely classical methods.

Console Networks for Major Computer Systems
A concept for interactive time-sharing of a major computer system is developed in which satellite computers mediate between the central computing complex and the various individual user terminals. These techniques allow the development of a satellite system substantially independent of the details of the central computer and its operating system. Although the user terminals' roles may be rich and varied, the demands on the central facility are merely those of a tape drive or similar batched information transfer device. The particular system under development provides service for eleven visual display and communication consoles, sixteen general purpose, low rate data sources, and up to thirty-one typewriters. Each visual display provides a flicker-free image of up to 4000 alphanumeric characters or tens of thousands of points by employing a swept raster picture generating technique directly compatible with that of commercial television. Users communicate either by typewriter or a manually positioned light pointer.

Specifications for Multifunction Storage Unit Type I
The Multifunction Storage Unit, Type I is a storage device capable of storing geometrical information in visual display form. The storage is accomplished by means of an electrostatic storage cathode ray tube. The Storage Unit consists of this storage tube and its associated circuitry. Associated circuitry is considered to be all circuitry required by the storage tube itself which is necessary to make the unit a self-contained storage unit. The following six external signals are all that is required in order to write, store and erase in the unit: vertical deflection signal, horizontal deflection signal, gate signal, z axis signal, erase signal (local or remote) and AC power. The erase signal causes the entire screen to be erased and primed for writing.

Dependence of the Vertical Excitation Energy of Benzene on the Size and Force Constant of the Excited State
Griffing1 computed the vertical excitation energy for the first electronic transition of benzene as a function of the carbon-carbon distance (rn) within the Sklar valence bond (SVB) and Goeppert-Mayer and Sklar molecular orbital (G1SMO) methods to evaluate the change on excitation of the carbon-carbon equilibrium internuclear separation (rn0) and of the corresponding stretching force constant, f. While ring expansion was correctly predicted, both methods appeared to predict that f increases on excitation, contrary to experiment. We shall demonstrate a) that Griffing's paradox may be resolved if terms higher than the second power in rn are included in the energy expressions for the states and b) that a Huckel calculation leads to results qualitatively similar to those obtained from the more elaborate calculations.
