Abstract: ABSTRACT OF THE DISCLOSURE     In a well testing tool having a spring whose biasing force is supplemented by the hydrostatic pressure in the well annulus at the testing depth, a method and apparatus for isolating the spring from the pressure in the well annulus utilizing the pres-sure differential between the well annulus and the testing tool bore which exists after the formation is isolated and for main-taining the isolation of the spring force during subsequent in-terior bore pressure increases such as during formation treating operations.  An isolation valve is provided whose closing force is generated by isolating the testing tool bore from the well annulus, and then increasing the well annulus pressure above the hydrostatic pressure.  The pressure differential thus created is utilized to close the valve.  Uni-directional acting means is provided in the isolation valve responsive to the interior bore pressure such that when the interior bore pressure is increased subsequent to the closing of the isolation valve, the uni-directional acting means will not cause the isolating valve to reopen, but will nullify the effect of the subsequent pressure increase such that the valve will remain closed.  The opening force is provided by compressing a spring when the valve is closed, thus allowing the isolation valve to reopen when the pres-sure in the annulus is returned to hydrostatic.  An isolation valve is provided which is normally open, which closes only after the well annulus pressure exceeds a reference pressure trapped in the bore of the testing tool by a predetermined amount, and which remains closed during subsequent pressure increases in the bore of the testing tool.

Each inserted auxiliary pulse series is produced from the previously inserted auxiliary pulse series in accordance with a predetermined formation principle.          At the receiver end the pulse series transmitted by the transmitter is stored in a storage and the stored pulses compared with com-parison pulse series in order to determine coincidence of the stored auxiliary pulse series with the comparison pulse series.          The comparison pulse series possess the same number of pulses and are formed according to the same formation principle as the auxiliary pulse series.  After determination of coincidence of the comparison pulse series with the stored auxiliary pulse series the latter are separated from the stored information pulse series.

Abstract: ABSTRACT:        An automatic control system for a scintilla-tion camera which is integrated in tile image pick-up device, with photomultipliers of the camera, notably one used for gammagraphy. A configuration of radio-active sources cooperates with the said photomul-tipliers in order to form interaction regions which are "seen" by the said photomultipliers at a given angle and in a number which is dependent of the po-sition of the photomultipliers relative to the sour-ces. The circuits cooperating with the said system are analog or digital circuits. Control is dependent on the one hand of the signal which is obtained by comparing a reference signal and a signal which is supplied by each photomultiplier in a ratio which is determined by the number of regions "seen" by the photomultiplier, and on the other hand of the num-ber of regions which contributes to the formation of the reference signal.

Abstract: ENVIRONMENTAL CONTROL OF A BUSHING   Raymond H. Cates, Jr. Walter L. Martin, Jr.    Sumpter D. Smith ABSTRACT OF THE DISCLOSURE           A method and apparatus for eliminating short term yardage variation in the formation of glass filaments is disclosed. This method involves additionally cooling the bushing tips from which molten glass is drawn to form filaments utilizing a separate cooling means in addition to the fin coolers normally employed.  The additional cooling means removes heat at a rate of from about 1,000 Btu's per hour to about 3,000 Btu's per hour (293 to 879 watts) based upon a drawing rate of about 35 to about 70 pounds of glass per hour (77 to 154 kilograms per hour).  The method further involves either forming a controlled stream of air across the bushing tips from above the additional cooling means or preventing the direct impingement of air upon bushing tips by blocking the air with the additional cooling means, to provide a more stable thermal environment under the bushing.
