Abstract: ABSTRACT OF THE DISCLOSURE         In one embodiment, a closed cycle gas turbine system employs a precooler for cooling the gas prior to compression.          A closed loop coolant circuit for the precooler includes a primary heat exchanger.  A secondary heat exchanger is provided which may be employed during periods of peak demand on the turbine system to provide additional cooling for the coolant in the closed loop coolant circuit for the precooler.  The secondary heat exchanger may also be employed to transfer heat in the reverse direction during periods or time in which the primary heat exchanger is operating at high effectiveness to provide storage of a fluid at low temperature to enhance oper-ation in the initially described mode.  In another embodiment, a similar coolant circuit operates in conjuction with a con-denser for a steam power electrical generating facility.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for indicating the location of particular information, such as instructions, represented by predetermined signals previously recorded on a record medium.  An array Or light emitting sources is selectively energized to indicate the position of the particular information relative to the length of the record medium while the array is scanned in synchronism with the scanning of the record medium to detect the presence of such predetermined signals.  Indexing means sequentially conditions each of the light emitting sources to be energized during scanning and a temporary storage circuit stores a representation of a detected predetermined signal until a light emitting source is conditioned.

Abstract: ABSTRACT OF THE DISCLOSURE    A battery-charging system includes a first charging circuit connected in series with a plurality of battery cells for controlled current charging.  A second charging circuit applies a controlled voltage across each individual cell for equalization of the cells to the fully charged condition.  This controlled voltage is determined at a level above the fully charged open-circuit voltage but at a sufficiently low level to prevent corrosion of cell components by electrochemical reaction.  In this second circuit for cell equalization, a transformer primary receives closely regulated, square-wave voltage which is coupled to a plurality of equal secondary coil windings.          Each secondary winding is connected in parallel to each cell of a series-connected pair of cells through half-wave rectifiers and a shared, intermediate conductor.

Abstract: ABSTRACT OF THE DISCLOSURE       EXPLORATION SYSTEM FOR CROSS-STEERING AND STACKING SEISMIC   DATA USING A SAWTOOTH TRAVERSE OF SHOT POINTS CENTRALLY SPACED BETWEEN AT LEAST A PAIR OF LINEAR DETECTOR SPREADS        In areal seismic exploration, seismic impulses are generated successively at locations spaced along a centrally located, asymmetric sawtooth shot-point line which regularly crosses a median line coincident with the line of survey.      Seismic waves resulting from each impulse are detected at at least a pair of detector spreads each parallel to the median line, but offset from each other a distance equal to an integral multiple of the vertical offset of the shot-point line.  Preferably the detected signals are summed on a cross-steered basis, such that the resulting traces associated with crossed sets of center-points normal to the survey line provide directional ("dip") information to better indicate areal subsurface structure.          Additionally, the detected signals can be stacked on a common depth point basis (CDPS).
