Abstract: Radiation from fission or fusion nuclear reactors or the like is converted to chemical energy form in a process simplifying handling of the constituent materials and operable at moderate temperatures and pressures with conventional plant construction materials. Thus a chemical in liquid phase is irradiated to form precipitate solid and gaseous constituents. Preferable chemicals are SnCl.sub.4 in the process SnCl.sub.4(1) .fwdarw.SnCl.sub.2(s) +Cl.sub.2(g) and TiCl.sub.4(1) .fwdarw.TiCl.sub.2(s) +Cl.sub.2(g). To obtain titanium metal the following step is used: ##STR1## This latter process also stores enough energy to release hydrogen from water.

Abstract: The depth and lateral offset position of an underground pipeline or the like is calculated by a surface located instrument carrying two spaced sets of orthogonal antennas sensing electromagnetic energy induced in and radiated from the pipeline. The resulting four signals are compared in amplitude to derive by simple triangulation calculations the depth and offset distances in a simple computer-display unit. Thus a set of continuous reading may be made automatically by a self-contained portable unit as an operator tracks the pipeline to make a survey. The readings may be recorded upon a medium advanced by a measuring instrument as a survey progresses along a pipeline.

Abstract: Efficiency of an open-cycle air conditioning apparatus and method for heating and cooling is improved and the economy of external power is increased both with respect to cost and energy consumption by providing a combination of a primary heater and a secondary heater for heating the regeneration stream for regenerating the desiccant means in the air conditioning apparatus. The thermal source for the primary heater may utilize waste heat or solar energy which is transferred to a solid phase thermal storage means by a gaseous phase heat exchange medium. The thermal energy may be transferred from the thermal storage means to the regeneration stream of the open-cycle air conditioning apparatus either directly by passing the air stream over the solid phase thermal storage means or indirectly by passing liquid in an enclosed system through the solid phase thermal storage means and the regeneration stream.

Abstract: A process and apparatus for drying air by a continuous atmospheric pressure and low pressure drop system wherein the adsorbent body is a wheel of thin sheets or layers of fibrous material containing about 10 to 90% by weight of a finely divided crystalline molecular sieve material. The process and apparatus is especially useful for drying air for confined areas down to and less than 0.001 lbs. of moisture per pound of air.

Abstract: A process for open-cycle air conditioning which affords economy of external power both with respect to cost and energy consumption by providing a low-temperature heater and a high-temperature heater for regenerating the sensible heat exchanger and desiccant when the apparatus is used for cooling and the enthalpy exchanger when the apparatus is used for heating. The power source for the low-temperature heater can utilize solar energy, waste boiler heat, waste process heat, nuclear reactor heat and the like. The power source for the high-temperature heater can be an open flame burner or other conventional heater.

Abstract: A process for air cleaning by the removal of water and one or more undesirable gases such as NO.sub.x, SO.sub.x and CO.sub.2 by a continuous atmospheric pressure and low pressure drop system wherein the adsorbent body is a wheel of thin sheets or layers of fibrous material containing about 10 to 90% by weight of a finely divided crystalline molecular sieve material. The process is especially useful for the removal of NO.sub.2 from confined areas.

Abstract: Improved metallic heat exchange apparatus particularly useful in a wheel-like form as a sensible heat exchange wheel in an environmental control apparatus. The heat exchange apparatus is constructed of multiple layers of metallic "honeycomb", with the apertures of the honeycomb layers axially parallel and offset with respect to each other. The multiple layers provide thermal discontinuities so that the face to face temperature gradient of the heat exchanger is continuous. The heat exchange apparatus of this invention is fireproof, a serious deficiency in prior art wax-coated sensible heat exchange wheels used in environmental control apparatus.
