Abstract: INVERTED CONE STUFFING BOX            ABSTRACT          A stuffing box for use in oil and gas wells having improved sealing.  A plurality of ring-like packing glands each has an outer surface defining an inverted frustco-conical shape and a bore therethrough also defining an internal inverted frusto-conical surface whereby the glands nest upon one another in cup-like fashion.  A ring-like seal seat also has a bore forming an inverted frustco-conical inner surface which, in assembly, carries the nested glands.  The inner wall of a stuffing box body defines a cavity which contains the assembly, the seat thereof being carried by a lower shoulder portion defined by the body.  A cylindrical gland cap has a lower gland follower edge portion which exerts downward pressure on the end of the uppermost gland.  The vertical bore through the body, seat, glands, and gland cap is adapted to receive a vertical reciprocating polished rod in coaxial alignment therewith whereby the downward pressure of the gland follower effects sealing of the inner and outer surfaces of the glands to the rod and to the inner wall of the body, respectively.  Sealing is pressure-enhanced by borehole pressure, and any misalignment of the rod is compensated for by providing for horizontal movement of the seat, glands, and gland cap relative to the box.

Abstract: MOVING MAGNET DISC DRIVE ACTUATOR          Frank G. Gibeau Paul L. Farmer ABSTRACT      A transducer actuator assembly (10) for a rotating disc memory apparatus has at least one pair of coils (40, 41) symmetrically spaced from a center plane of a linearly moving carriage (21) where the coils are stationary with respect to a fixed actuator base (11) and surrounding spaced center poles (34) of a magnetic pole piece flux return structure (31, 32, 33) having an E-Shaped configu-ration closed by pole plate (38).  At least one pair of magnets (24a-d or 60, 61) are affixed to and extend hori-zontally from the sides (23) of the carriage and are spaced in longitudinally extending air gaps (45-48, 49) between the fixed coils and linearly extending pole piece portions (32, 33).      Due to the low mass and small envelope size of the moving carriage-magnets subassembly and the removal of the heat generating coils from the carriage, very rapid access times with high location accuracies are possible along with minimization of magnet field effects on the memory discs being accessed.

In use of the heater, gas (or oil) is burnt at the burners and control units (13, 14),  and hot air is sucked through the tubes (7, 8) by the suction fan units (16, 17).            The provision of two U-tubes (7, 8)  provides for a greater heat output than with the use of a single tube for a given length of heater and the provision of side reflector plates (3, 4) end reflector plates (5, 6, 9, 11, 10, 12) and the V-shaped channel (15) results in a reduced (and more uniform) spread of heat radiated by the tubes (7,  8) meaning that the heater may be disposed a greater height above ground to give a useful heating effect at ground level compared with a conventional radiant heater.  Also, the overall shape of the radiant heater is such as to restrict the loss of heat due to convection.

Abstract: ABSTRACT OF THE DISCLOSURE      A signal generator circuit for a television receiver employed in a Videtex or CAPTAIN system Comprises a reference signal oscillator for producing a reference signal and a synchronizing signal generator for generating a horizontal synchronization signal synchronized with the reference signal.  A frequency divider is responsive to the reference signal for producing a color sub-carrier signal.          A phase-locked loop is responsive to the sub-carrier signal and includes a voltage-controlled oscillator.  The volt-age-controlled oscillator produces an output signal syn-chronized with the sub-carrier signal and having a series of rising edges.  A rising edge of the sub-carrier signal periodically coincides with a rising edge of the signal from the voltage-controlled oscillator.  A detector detects a time when a rising edge of the sub-carrier signal coincides with a rising edge of the output siqnal of the volt-age-controlled oscillator, and a clock signal is then generated synchronized with the output signal of the volt-age-controlled oscillator and having a series of falling edges.  The horizontal synchronization signal generator and the clock signal generator are controlled so as to ensure that the rising edge on the horizontal synchronization signal coincides with a falling  edge of the clock signal.          This ensures an accurate count of the pulses for determining the horizontal  position of a display by the receiver and prevents horizontal jitter in the display.

Abstract: ABSTRACT OF THE DISCLOSURE An automatic flight control system having two digital processors receives sensor data over a bit serial data bus through a serial-to-parallel converter.  The converter formats the data into bytes corresponding to the data parameters from the sensors.  One of the proccessor controls the bus timing and receives the data bytes which are simultaneously applied to an independent data storage element.  An independent address sequencer provides sequential addresses to the independent data storage element at which to store sequential data bytes from the converter.  After an entire data frame is stored in the independent data storage element, the second processor performs a bulk move of the data into its local data storage element.  The sensors are configured in data subsystems which provide respective messages, each message containing an address identifying the subsystem.  These addresses are utilized for directing the data messages to respective areas in the independent data storage element.  The other processor compares addresses to determine that the data messages are not scrambled.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a process of minimizing damage of the formation surrounding perforation channels in a subterranean formation during workover and completion operations when the need exists to temporarily seal the perforation channels and subsequently clean them before packing the channels with gravel.  The process comprises filling the perforation channels with a water soluble particulate sized salt to form a highly permeable salt pack therein, sealing the salt pack with a low permeability Film by treatment with a low fluid loss treating fluid having an aqueous phase in which the water soluble particulate sized salt is substantially insoluble, and thereafter, when desired, removing the low permeability film from the surface of the salt pack and dissolving the salt pack in an aqueous fluid in which the water soluble particulate sized salt is soluble before placing gravel within the perforation channels or before placing the well on production.

Abstract: ABSTRACT     The invention provides an ammeter specially suited for measuring the currents passing in high voltage, high power A.C. lines and, when required, storage of the resultant information, together with time of day and date over an extended period of time.  The ammeter employs two C-shaped cores defining between two of the core arms a relatively large permanent gap that can pass the power line to facilitate mounting on the line using a live-line stick.  One embodiment intended for mounting for an extended period of time also employs a clamp that can be manipulated using the stick to clamp it to the line and unclamp it, the clamp and core being related so that the power line passes through the center of the space between the cores.  An embodiment intended for "spot" measurements has a locating member that performs the same function.  A third device has the locating member in two parts that pivot to enable a large power conductor to pass through the slot in the locating member to the closed locating end thereof.  The devices may be characterized as "current transducers" and the two cores carry respective coils that are oppositely wound on the core arms opposite to one another.  The A.C. signal from the coils is converted to a digital signal and is fed to an external display and/or is recorded in a non-volatile memory together with the time and date data using a microcomputer that is powered only during the short interval required for measuring, thus conserving battery power.
