Abstract: Abstract of the Disclosure Apparatus and methods for measurement of total organic carbon content of water, particularly of low relative organic content, is described which features a single sample cell for exposure of a static sample to ultraviolet radiation comprising electrodes for measuring the conductivity of the water.  The conductivity is monitored as a function of time and the second time derivative of the conductivity signal is monitored to indicate when the oxidation reaction has been completed.          Compensation for the contribution to conductivity of the water sample made by the instrument is achieved by subtracting a quantity porportional to the first time derivative of the conductivity at a time when the second time derivative reaches zero, indicating that the oxidation reaction is complete, from the change in the total conductivity measurement, the remainder being equal to the contribution to conductivity made by oxidation of the organic content of the water.

Abstract: APPARATUS AND METHOD FOR CONTROLLING    A REFRIGERATOR IN LOW AMBIENT TEMPERATURE CONDITIONS                          Abstract A refrigerator control for operating a refrigerator which may experience an abnormal temperature condition due to operation in low ambient temperatures includes a temperature sensor for sensing the temperature of a portion of a refrig-erator compartment in order to detect an abnormally low temperature in another portion of the compartment.  If the compartment temperature at the end of a predetermined length of time since cooling was last supplied to the compartment is below a predetermined value, then an abnormal condition is assumed to exist and corrective action is taken to eliminate the abnormal condition.  A preferred form of corrective action is to prevent compressor re-energization until the compartment temperature reaches a second predetermined value.

The lnlet to the houslng ls ln the upper chamber, whlch ls upstream of the lower chamber, and the outlet ls through the lower chamber and communlcates wlth the lnterlor of the fllter element.  Thus, blood enters the upper chamber and flows to the lower chamber where lt passes through the fllter element from the outer slde to the lnterlor to remove mlcroemboll such as gas bub-bles, fat emboll and agglomerates, the flltered blood exltlng through the outlet.  ln order to remove a substantlal amount of the gas ln the blood, and partlcularly gross bubbles, upstream of the fllter element, the upper chamber ls cyllndrlcal and the lnlet dlrects the blood tangentlally to flow around the perlphery of the chamber.  An annular baffle extendlng around a maJor por-tlon of the chamber malntalns the perlpheral flow whlch produces a centrlfugal actlon causlng the blood to flow at the wall of the chamber and the gas to separate and move to the central portlon where lt ls vented through a hydrophoblc membrane coverlng the central portlon of the top wall of the chamber.  Blood from the perlphery of the upper chamber flows down to the lower chamber through a sponge rlng whlch removes addltlonal gas bubbles by causlng the latter to coalesce lnto larger bubbles whlch move radlally lnwardly of the rlng and rlse to the upper chamber where they also are vented through the membrane.  Any gas bubbles whlch remaln ln the blood and whlch are larger than the acceptable slze are blocked by the fllter element.  The bubbles at the fllter element eventually coalesce lnto larger bubbles whlch break away from the fllter element and rlse to the upper chamber where they are vented through the membrane.

Abstract: ABSTRACT           A dynamic focus circuit for a television display picture tube provides a focus voltage having scan rate modulation.  The parabolically shaped voltage which is produced across the S-shaping capacitor in a deflection system is coupled by a transformer having a primary winding coupled between the junction of the S-shaping capacitor and the deflection winding and a power supply point having substantially the same average DC potential. Therefore, substantially no DC current flows through the transformer primary winding, which permits a relatively small transformer to be used without saturation of the magnetic core and without the need for a coupling capacitor for DC isolation.
