Abstract: ABSTRACT OF THE DISCLOSURE     Method and apparatus for improving the operation of forced-air-cooled steam condensors having a bank of air-cooled heat exchangers connected between steam lines and condensate conduits.  Air is forced through the heat exchangers by fans, and shutters are provided to either discharge the spent air to atmosphere or to recirculate the spent air into the fan inlets to mix with fresh outside air.          The steam pressure in the steam line is sensed along with the temperatures of the condensate in each exchanger and of outside air.  The condensate conduits are in the recirculation path of spent air, and the fan is adjustable to control the quantity of air forced through the exchangers.  By controlling the shutters and the fans in response to the pressure and temperatures, a highly-efficient cooling effect is achieved.  According to the invention there are provided sensor-governed motor-driven roll-shutters (11), which more or less can screen the heat exchangers (12) and thereby create a recirculation channel (17) for the warmed up air, and there are furthermore provided sensor-governed adjustments of the blade angles of fans (13). The condensor (2) has an upper steam pipe line (9) and connected thereto the heat exchangers (12), which preferably are arranged trapezoid-like in two parts covering the lower fans (13), one for each so-called module, whereby a roll-shutter (11) is arranged outside of and at distance from each heat exchanger part, and whereby the roll shutters are rolled up close to the steam pipe-line (9).

Abstract: APPARATUS AND METHOD FOR MONITORING STORED MATERIAL     Abstract of the Disclosure An apparatus and method for monitoring stored material is disclosed.  Material to be stored and monitored is placed within the  innermost container of a  series of nested containers and monitoring fluids are circulated in a closed loop of fluid flow through the spaces between the nested containers.  Monitoring devices are used to analyze said monitoring fluids to detect leakage of the stored material from the innermost nested container and to detect the migration of external fluids into the series of nested containers.  A computer based monitoring system continually checks the values of various parameters of the monitoring fluids to immediately detect and report the presence of stored material or external fluid in the monitoring fluids.  The stored material may then be immediately retrieved from storage to repair leaks in the series of nested containers.  The invention is particularly suited for monitoring the storage of hazardous material such as radioactive waste material.    This invention relates generally  to the storage of material and in particular to the monitoring of storage containers to detect leakage of material from the storage containers and to detect the migration of fluids into the storage containers.  The stored material may be immediately retrieved from storage when the leakage of material from the storage containers is detected or when the migration of fluid into the storage containers is detected.  The invention is particularly suited for monitoring the storage of hazardous material such as radioactive waste material.

Abstract: Abstract of the Disclosure:         In an encoding system comprising a buffer circuit for successively storing variable length codes and for producing the stored codes at a predetermined rate as transmission codes, a controller produces a control signal which stepwise specifies a variable amount of the stored codes.  Responsive to the control signal, a preliminary processing circuit preliminarily processes the digital video signals into preliminarily processed signals which are dependent on the amounts and which are predictively encoded in accordance with an encoding rule by a non recursive predictive encoder into predictive error signals with information of the preliminarily processed signals preserved.  For use in the buffer circuit, a variable length encoder controlled by the control signal further encodes the predictive error signals into the variable length codes of code lengths related to the amounts.  The processing circuit may comprise at least one of a quantizer, a thinning circuit, and a band compression circuit.          A decoding system decodes the transmission codes in accordance with a decoding rule reversible to the encoding rule to produce reproductions of the preliminarily processed signals.  A combination of the encoding and the decoding systems is connected in cascade to at least one of an additional combination of the encoding and the decoding systems to repeatedly edit and/or dub video signals in a digital form.          The encoding system may additionally comprise an additional predictive encoder operable, when the amount is large to compensate for that visibly perceptible degradation of picture qualities which would otherwise result from a reduction in the numbers of bits representative of the predictive error signals produced by the non-recursive predictive encoder.

Abstract: A B S T R A C T         For the direction-finding of electromagnetic waves on ships, the ship's masts, above all, appear as a source of inter-ference downgrading the bearing measurement.  To suppress the interference a direction-finding system with a plurality of antennas and a plurality of different directional patterns are used, wherein at least two of the directional patterns have a null position in the fore and aft direction of the ship which favour-ably extends completely through the vertical plane that passes through the ship's fore and aft axis,  Particularly advantageous is the use of a twin loop consisting of two loop antennas, their loop planes being vertical and parallel to the ship's fore and aft axis.  A dipole voltage and a loop voltage are respectively coupled out of these loop antennas and are connected to the corresponding voltage of the other loop.  The arrangement is advantageously ex-tended to a crossed DF antenna  by a second twin loop arranged perpendicularly to the first.  The direction-finding system can be operated in conjunction with a conventional two-channel display unit.
