Abstract: A VACUUM BOX FOR USE IN HIGH SPEED PAPERMAKEING                        ABSTRACT OF THE DISCLOSURE          An improved vacuum box is described for holding a paper web onto a supporting fabric wherever velocity stresses would otherwise separate the web from its supporting fabric and expose the web to those stresses. Specially shaped vacuum boxes are fitted into the dryer "pockets" formed between the rows of a double row of adjacent drying cylinders and the web traveling a serpentine path between them. Pressure differential zones of the box hold the web onto its supporting fabric as the web and fabric travel between heated drying cylinders. A first zone leads the departure of the web and fabric from the web-wrapped cylinder to ensure that the web is positively held to the fabric as it leaves the cylinder. A second arcuate suction zone adjacent a fabric-wrapped cylinder evacuates grooves in the adjacent cylinder. This system holds the web onto its fabric, overcoming centrifugal stresses on the web, as the web-fabric combination passes about a cylinder with the fabric in direct contact with the cylinder and the web in indirect contact. A third pressure differential zone ensures the web is held to its supporting fabric as it travels from the fabric-wrapped cylinder to the next web-wrapped cylinder in the drying sequence. The vacuum box is provided with seals between box surfaces and the fabric that reduce air leakage into the box yet accommodate waste paper passing between the drying cylinder surfaces and box surfaces without damage to the box or fabric. Box end seals perform a similar function. The end seal is provided with a spring and pivot arrangement which cooperate to accom-modate waste. The top portion of the vacuum box is a curved surface designed to deflect at least a portion of the stray currents that typically flow in the dryer pockets and tend to lift the web from its supporting fabric. While the suction surface zones are generally open surfaces, a roller wearing surface may be provided which reduces the wear of the felt in passing through the vacuum box suction zones. The vacuum box may be compart-mentalized across the width of the machine to permit reducing vacuum demand during start-up of the paper web through the machine.

Abstract: ABSTRACT OF THE DISCLOSURE     A process of remanufacturing drilling fluid pump cylinder liners to increase the liner working life and to improve the same involving the steps of:  procuring a used liner having a hard metal alloy inner layer from a pump cylinder, and removing portions of the interior metal surface so as to form an enlarged diameter, accurately dimensioned cylindrical surface in the liner.  The remanu-factured liner is then supplied for use with a specially manufactured piston having an enlarged diameter.  Sequential remanufacturing steps can be carried out following several pumping and use cycles so that an original liner can be remanufactured multiple times.  Prior to the procuring step, the worn liner can be checked while it is retained in the pump cylinder to determine whether extraction is necessary. If desired the liner can be cleaned by a number of proced-ures and the outer diameter and configuration checked and, if necessary, resurfaced to restore the original outer surface dimensions.  The metal removing step is carried out by honing or by internal grinding.

Abstract: ABSTRACT            A programmable transversal filter utilizes a plurality of programmable multiplying device.  The result of each multiplication is summed by a summing circuit, thus providing an output signal.  The delay network comprises a plurality of signal sample and hold circuits which are selectively connected to the input bus in sequence, in order that one sample and hold circuit may store an analog signal sampled during the present time instant, with other sample and hold circuits storing a plurality of analog signals each of which has been sampled during a corresponding one of a plurality of preceding sample periods.  The filter also includes a plurality of reference sample and hold circuits which store error voltages equal to the error voltage component of the voltages provided by the signal sample and hold circuits. A first analog cross-point switch is utilized wherein each of said plurality of time delayed analog signals may be selectively applied to a selected multiplying device.  The filter tap weights remain fixed in the multipliers until reprogrammed, without the need for rotating the tap weights. A second analog cross-point switch is utilized to selectively connect the output voltage from the reference sample and hold circuits to the multiplier device, thereby eliminating the effect of the error voltages on the output voltage of the transversal filter.

Abstract: THE USE OF RECYCLED COMBUSTION GAS DURING TERMINATION      OF AN IN-SITU COMBUSTION OIL RECOVERY METHOD            ABSTRACT          A method for recovering viscous oil from a subterranean, viscous oil-containing formation by initiating an in-situ combustion operation in the formation using a mixture of oxygen and an inert gas having a low oxygen concentration, preferably about 21 vol. %.  After a predetermined period of time, the oxygen concentration is increased to a predetermined higher level, preferably within the range of 95 to 99.5 vol. %.  Once the oxygen concentration has reached the desired value, water may be simultaneously injected continuously or intermittently.  After a predetermined period of time, produced combustion gas enriched in carbon dioxide separated from the produced oil is compressed and recycled as a diluent for the injected oxygen in place of the inert gas.  Thereafter, wet in-situ combustion operation is continued and the oxygen concentration of the injected mixture of oxygen and combustion gas diluent is maintained at a predetermined value so that the concentration of oxygen in the produced combustion gas is maintained at a predetermined value low enough to avoid the danger of an explosion or burning of the production well.  After a predetermined period of time, injection of oxygen is terminated and injection of produced combustion gas and water is continued until the combustion front in the formation is discontinued.  Finally, water is injected to scavenge heat in the formation.  In-situ combustion may be initiated using air followed by injection of a mixture of oxygen and an inert gas having a predetermined oxygen concentration greater than air, preferably 95 to 99.5.vol. %.

Abstract: ABSTRACT         Signals to be cored are applied to the inputs of a linear signal amplifier, and of a multistage limiting amplifier having cascaded input and output amplifying stages.  A cored version of the signals, corresponding to the difference between a linearly translated version of the signals and a doubly clipped version thereof, is developed by a signal combiner responsive to the outputs of both amplifiers.  A variable coring level control voltage controls the distribution of gain between the input and output amplifying stages, substantially without disturbing the overall gain of the limiting amplifier, which is set to match the overall gain of the linear amplifier.  In an illustrative embodiment, the signals which are adjustably cored are horizontal peaking signals derived from the received luminance signal in a color television receiver.  An automatic peaking control system associated with output of the adjustable coring circuit opposes changes in peaking level that might otherwise accompany coring level adjustment.

Abstract: ABSTRACT OF THE DISCLOSURE          A process is disclosed for the solvent dewax-ing of wax containing hydrocarbon oils, preferably waxy petroleum oils most preferably waxy lubricating or transformer oils.   The process employs methyl tertiary butyl  ether as the dewaxing  solvent, either alone or in combination with other dewaxing solvents such as ketones, halogenated hydrocarbon anti-solvents, and mixtures thereof.  The use of methyl tertiary butyl ether as a dewaxing solvent, or in combination with conventional  dewaxing  anti-solvents  permits  lower volumes of solvent to be employed  in the dewaxing process while simultaneously producing an oil of lower wax content and lower dewaxed oil pour point at the same filter temperature as that commonly employed using conventional dewaxing solvents.  Dewaxed oil yields for equivalent pour point are 3 to 4% higher with the MTBE system.
