Abstract: Colloidal corrosion products which are referred to as crud are removed from nuclear reactor coolant streams by suspending zirconium oxide particles in the coolant stream. The crud will be attracted to the surfaces of the zirconia particles and caused to agglomerate thereon. Such zirconia/crud agglomerates may be readily filtered from the coolant. By providing scavenger particles which comprise active areas of zirconia on basically magnetite particles, after the crud is agglomerated to the active zirconia surfaces, the agglomerates may be removed from the coolant utilizing magnetic separation principles.

Abstract: Although known jitter meters containing sampling-type phase comparators supply a PAM signal which directly and linearly reproduces the phase/time function, they have a modulation range which is too narrow and is less than +/- pi/2 at high bit repetition rates. The novel method is intended to operate directly on arbitrary information-carrying digital signals, to convert the phase directly into a PAM voltage and have a modulation capacity which is basically not restricted. The measurement result is composed of a coarse phase value and a fine phase value. For this purpose, the jitter-free bit clock period is subdivided into n part periods and from the ordinal number of the part period into which the digital signal pulse edge to be determined falls, a coarse phase value is determined. The fine phase value is supplied by a sampling-type phase comparator the ramp of which is not much longer than one part period, is started with a defined delay compared with the end of the part period concerned and is sampled with the digital signal pulse edge which is delayed in a defined manner. Measuring of the jitter modulation of digital signals containing zeros. <IMAGE>

Abstract: A relational database system having mixed data comprises means for selectively designating a column in a database table as being for single byte character set data only. Preferably, the user application can specify the subtype of character data within a column as the column is created or added by specifying FOR SBCS or FOR MIXED in either the CREATE TABLE statement or the ALTER TABLE statement. This can be done by specifying the subtype of the character data types including CHAR, VARCHAR, and LONG VARCHAR. 
     Along with specifying the subtype as either for single byte data or for mixed data, means are preferably provided for specifying the codepage to be used for the column of the table in the database. The subtype of the character can then be recorded in terms of the code page attributes of the character data type as stored in the database system catalogs. This encoding scheme provides an efficient method of determining whether a column is only for single byte character set data or mixed data, and at the same time knowing the correct codepage that is to be used for that column simply by querying the code page columns within the database system catalogs.

Abstract: A snubber circuit comprising two stages regulates the gate current of a MOSFET (12) in relation to the drain-to-source voltage at turnoff to clamp transient inductive voltages to a nondestructive level. At the onset of the turnoff, a current source (28) is activated to discharge the gate capacitance, and the snubber circuit controls the magnitude of such current in relation to the sensed drain-to-source voltage to stabilize the drain-to-source voltage at a nondestructive level. When the drain-to-source voltage approaches its limit value, a current injection circuit (76) supplies additional current to the gate (g) to sustain the MOSFET conduction, again in relation to the sensed drain-to-source voltage. When the inductive energy stored in the load (14) is substantially dissipated, the drain-to-source voltage falls; at such point, the current injection circuit (76) is disabled and the conduction of the current source is increased to complete the turnoff of the MOSFET.
