Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a process for the plugging of a porous formation which may be encountered during the drilling of a well.  The process entails plugging of the porous formation by means of a polymeric solution containing pseudo-emulsion spheres.     These particles penetrate the pore structure within a formation.   Eventually, sufficient numbers of the spheres will accumulate within the pores, blocking further flow through the formation by both the pseudo-emulsion particles and any aqueous solutions.   The pseudo-emulsion system is formed by a process which includes the steps of forming a solvent system of an organic liquid or oil and a polar cosolvent, the polar cosolvent being less than 15 weight percent of the solvent system, a viscosity of the solvent system being less than 100 cps; dissolving a neutralized sulfonated polymer in the solvent system to form a solution, a concentration of the neutralized sulfonated polymer in the solution being 0.01 to 0.5 weight percent, a viscosity of the solution being less than 200 cps; and admixing or contacting said solution with 5 to 500 volume percent water, the water being immiscible with the organic liquid and the polar cosolvent and neutral-ized sulfonated polymer transferring from the organic liquid to the water phase, thereby causing the water phase to gel (i.e. thicken).

Abstract: Abstract of the Disclosure Helical  scan  magnetic  recording  and  reproducing system of the type where time compressed audio signals are recorded in extensions of the video tracks.  In order to avoid a time delay of the reproduced audio relative to its original relationship to  the video,  additional  audio playback heads are located on the helical scanner so as to read the audio information sufficiently in advance of the video to allow restoration of the original audio/video synchronism.  The arrangement allows full flexibility in audio editing even when the recorded audio signals are digitally   encoded   and    interleaved.  A   similar arrangement can be employed to produce pre-recorded tapes having  time  advanced  audio  such  that  synchronous audio/video  is  reproduced  on  conventional  playback reproducing systems.

Abstract: MULTIPLE FUNCTION VALVE ASSEMBLY            Abstract of the Disclosure A valve assembly is provided for a paint color change system for directing paint to spray guns from either of two supply lines selectively while con-necting the other line to exhaust, and simultaneously controlling the paint pressure as a function of pilot air pressure.  A valve block contains two pairs of poppet valves, each pair having a common inlet chamber connected to one of the paint supply lines and contain-ing a pair of poppets each biased toward a seat for controlling flow to an outlet chamber, and a pilot air operated diaphragm in each outlet chamber coupled with a poppet for regulating the position of the poppet in accordance with the paint pressure in the outlet chamber and pilot air pressure.  The outlet chambers are connected to an exhaust line and the paint spray guns respectively so that the two pairs of poppet valves acting in concert under control of two pilot air signals can control which paint line is connected to the spray gun or to the exhaust as well as regulate the pressure or volume of paint flowing to the spray guns.

Abstract: ABSTRACT         The invention relates to wabbler plate engine mechanisms.  One such mechanism has a wabbler plate rotatably mounted on a wabbler carrier which is in turn inclinably mounted on a crankshaft in a crankcase.  The wabbler plate has a plurality of arms which are coupled to pistons slidably mounted in cylinders arranged around the axis of the crankshaft.       As the crankshaft rotates, each arm oscillates laterally relative to its respective piston and a stabilizer mechanism comprising ball races on the wabbler plate and a ball carrier on the crankcase, is included to prevent the oscillations from unbalancing the mechanism.  This construction is quite satisfactory but is not readily adaptable to provide for variable displacement.  Attempts have been made to incorporate this facility, but a successful solution has not yet been found.           In order to provide a variable displacement facility in an engine mechanism of the above kind, the present invention incorporates means for shifting the rotational axis of the wabbler plate along the axis of the crankshaft, and the ball carrier parallel thereto, while simultaneously altering the angle between the crankshaft axis and the wabbler carrier to vary the stroke of the mechanism.  The invention also provides for the effective lengths of the ball races to be variable to accommodate the alteration of said angle.

Abstract: TURN-OFF CONTROL MEANS FOR AN AC-TO-DC ELECTRIC POWER CONVERTER ABSTRACT OF THE DISCLOSURE      In the propulsion system of an electric locomotive, a-c wayside power is converted to direct current for the traction motors by a plurality of phase-controlled rectifying circuits having serially connected outputs.  To improve power factor, forced commutation means is provided for turning off the controllable valves in one of the circuits at a desired "extinction angle."  This angle is varied with motor speed, but its effective range of variation is restricted so as to avoid undesired leading power factor at low speeds, to optimize power factor when the locomotive is running at full power, and to prevent misoperation when the level of load current is low.

Abstract: ABSTRACT OF THE DISCLOSURE         Unique EPROM and EEPROM devices are provided with a composite dielectric layer between the control gate and the floating gate which is sufficiently thick to provide electrical and physical integrity but also has a high equivalent dielectric constant.  The use of the composite dielectric layer alleviates certain problems experienced in the prior art EPROM and EEPROM devices which utilize a polycrystalline silicon floating gate and a polycrystalline silicon control gate separated by an SiO2 dielectric layer, such as the problems of sharp silicon points polysilicon grain growth causing low dielectric breakdown strength.  In contrast to the prior art, a composite dielectric layer serves as a partially relaxable dielectric between the control gate and the floating gate of an EEPROM or an EPROM.  The composite dielectric layer provides high capacitance between the floating gate and the control gate without the insulative and breakdown problems encountered with prior art thin dielectric layers, with electron injection taking place through the gate oxide between the drain extension and the floating gate (EEPROM), and between the channel and the floating gate (EPROM).  In another embodiment of this invention, the composite dielectric layer is implemented between the drain extension (EEPROM) or the channel (EPROM) and the floating gate and serves as the tunnel oxide.

Abstract: FINWHEEL SERVO DRIVE FOR PACKAGING MACHINE         ABSTRACT OF THE DISCLOSURE        In a horizontal packaging machine for wrapping and sealing articles with flexible films, a servo control system for maintaining synchronism between the finwheel drive, the in-feed conveyer and the cut-off knife assembly so that proper registration of the graphic art work on the packaged article is achieved. The finwheels are driven by a D.C. motor whose armature windings are connected to the output of a servo amplifier.  A master tachometer driven by the horizontal wrapper's drive motor provides a voltage which is directly proportional to the angular velocity of that drive motor. The output from the master tachometer is passed through a calibrating network and into a first input of the servo amplifier circuit.  A second tachometer is coupled to the finwheel shaft and produces a feedback signal proportional to the angular velocity of the finwheels. The feedback signal is applied to the second input of the servo amplifier and functions to control the D.C. current driving the finwheel drive motor. The system also includes a digital logic network which senses a reference mark on the film from which the package is formed along with the rate at which the end-seal cutting blade is rotating to produce a supplemental or vernier control signal for adjustment of the rotational speed of the finwheel.
