Abstract: ABSTRACT OF THE DISCLOSURE     An automatic pressure sensitive regulation assembly and process is provided for use with a non-mechanical particulate solids flow apparatus.  The automatic pressure sensitive regulation assembly comprises first and second pressurized fluid distributors.  The first pressurized fluid distributor provides incipient fluidization of the particulate solids in the vicinity of the automatic pressure sensitive regulation assembly and an attendant hydrostatic pressure.  The second pressurized fluid distributor senses variations in the hydrostatic pressure as a function of the particulate solids level, and in response thereto directly varies the flow of pressurized fluids to the downstream end of the particulate solids flow apparatus to change the rate of flow of particulate solids at the same rate as received.

Abstract: ABSTRACT OF THE DISCLOSURE          A document feeding method and  æ apparatus for frictionally (non-sprocket) feeding computer forms web having sprocket holes to the imaging station of a copier for copying, compatible with individual document sheet feeding.  After automatically determining that a computer forms web rather than an individual document sheet is being frictionally fed to the imaging station the computer forms web is automatically frictionally fed incrementally in selected incremental lengths and registered to the imaging station with a controllable frictional servo-drive system without engaging the sprocket holes.  A system is provided for sensing and accumulating first signals corresponding to the movement of the controllable frictional drive system, and for sensing and accumulating second signals corresponding to the number and position of sprocket holes in the computer forms web being so frictionally fed, including a system of validating sensed holes as being sprocket holes by validating hole dimensions and positions.  A system is provided for compensating for slip in the frictional feeding of the computer forms web by comparing the first and second signals to maintain registered stopping positions for the controllable drive system for the selected incremental lengths of computer forms web.  The disclosed slip compensation utilizes a resettable sprocket hole zone boundary system.          There is also disclosed automatic compensation for missing, plugged or torn sprocket holes.

Abstract: "TELEPHONE LINE INTERFACE CIRCUIT"           ABSTRACT OF THE DISCLOSURE         An interface circuit for providing power and signal voltages to a telephone line under the control of a microcomputer within the telephone exchange comprises four  charge pumps,  each comprising a pair of driver/ amplifiers which charge a pair of capacitors through a first diode with two further diodes discharging the capa-citors to charge a capacitor connected across the tele-phone line.  The four charge pumps are arranged symmetri-cally to provide positive and negative potential at the TIP terminal and positive or negative potential at the RING terminal.  Modulation of the voltages to transmit a desired signal is obtained by modulating the power volt-age supplied to the amplifier/drivers.  The current drawn by telephone  line  is measured by sensing the current drawn from the voltage source by the amplifier/drivers and this is used to extract the received signal from a telephone line and also to extract a measurement of peak current drawn from the TIP and RING leads separately.          The amplifier/drivers  are driven by continuous  square wave signal.

Abstract: STIMULATION OF OIL AND GAS WELLS WITH     PHOSPHATE ESTER SURFACTANTS            ABSTRACT:      Crude oil and gas production wells, which no longer produce oil or gas utilizing conventional primary and secondary means of recovery, can be returned to produc-tion by treatment comprising addition of a non-aqueous solution of certain phosphate ester surfactants followed by successive treatment with water or a hydrocarbon. Increased production also can be obtained in low-produ-cing oil and gas wells by similar treatment with certain phosphate ester surfactants.  Subsequent to treatment of a producer well, the phosphate ester surfactant is forced into the formation utilizing water or a hydro-carbon and said surfactant is allowed to remain in the producing well, for an effective period of at least 12 hours.   Thereafter, pumping and/or conventional  fluid drive means are then utilized to recover oil or gas from the subterranean oil or gas formation.   The amount of non-aqueous surfactant solution utilized is sufficient to permeate the oil or gas subterranean formation in the area immediately adjacent to the producing well bore and up to a radius therefrom of about 20 feet.

Abstract: TITLE OF THE INVENTION  DOUBLE GRIP, RELATIVE MOTION TUBE PULLER          ABSTRACT     Both an apparatus and a process for pulling tubes from a tubesheet with two relatively movable gripping means are disclosed herein. The apparatus of the invention is a tube puller which has upper and lower gripping means for gripping the section of the tube surrounded by the tubesheet. The two gripping means are mechanically linked together by means of an extendable connecting assembly. This assembly includes an outer sleeve where the lower gripping means is located, and a middle sleeve where the upper gripping means is located which is slidable a predetermined distance within the outer sleeve. In the process of the invention, a tube puller as heretofore described is inserted into the mouth of a tube. The lower gripping means is then engaged to the mouth of the tube. The upper gripping means is then engaged in a section of the tube beyond the tube mouth with the extendable connecting assembly in a contracted position. A pulling means including a hydraulic ram then applies a tensile force onto the lower gripping means in order to pull on the mouth of the tube and to plastically contract the outer diameter of the tube in the vicinity of the tubesheet. After such contraction occurs, the connecting assembly between the two gripping means extends to its maximum length, and the pulling means applies a tensile force to both the upper and lower gripping means. Both of the gripping means then coact to withdraw the tube from the tubesheet. The invention preserves the metallurgical properties of the section of tube between the two grippers, which is important when the tubes are being sampled for corrosion degradation.

Abstract: Abstract:         A method and apparatus for providing a movable display relative to information stored in a pixel bit map memory involves addressing a portion of the pixel bit map memory to define a visible display wherein the portion addressed represents a viewport  into the bit map memory, the pixel bit map memory storing a larger block of information than is included within said viewport.   The positioning of a cursor is controlled and the position of the cursor relative to the addresses for the bit map memory that represent the viewport  is detected in order to determine whether the cursor falls within the viewport.   The addresses as applied to the bit map memory are then altered to move the viewport toward the cursor so as to include the cursor within the visible display when the current position of the cursor is detected as falling outside the viewport.  The result is an improved manner of positioning a viewport relative to a large virtual screen.
