Title: Regeneration of zeolite hydrocarbon con-version catalysts
Inventor: DWYER F G
IPC: B01J29/90
Filed: 1971-03-26
Abstract: Regeneration of zeolite hydrocarbon conversion catalysts Crystalline aluminosilicate catalyst which has been deactivated in a hydrocarbon conversion carried out at  427 degrees C by a hydrocarbon deposit is reactivated by contacting the catalyst, in liquid or gas phase, with a polar material having a dipole moment in the gas phase of 1.00-4.00 Debye units during a period sufficient to ensure the elimination of a considerable part of the hydrocarbon deposit from the surface of the catalyst. Enables coke deposits, which cannot be eliminated by a purge of inert gas, to be effectively eliminated from the aluminosilicate catalyst. The polar material can be easily eliminated by a purge of inert gas. The polar compd is pref. methanol, ammonia., or water. The catalyst pref. is a crystalline zeolite with a silicalumina ratio of >=2.5.

Abstract: MAGNETIC RECORDING AND/OR                REPRODUCING SYSTEM     ABSTRACT OF THE DISCLOSURE     In a system  in which the polarity of the frequency con-verted chrominance signal or carrier is reversed during alternate lines of alternate fields recorded on alternate tracks on a recording medium and not reversed during the lines that make up the remaining alternate fields recorded in h-align-ment on the remaining alternate tracks positioned in inter-leaving relationship with the first-mentioned tracks, locgic-controlled switching means are provided to select the field intervals during which the plurality of the chrominance sub-carrier will be reversed in alternate lines. The same logic circuits can be used to control the switching during both recording and reproducing so that the alternate plurality reversal of the chrominance subcarrier will take place during the proper fields during reproduction of the recorded signals.          Furthermore, the flip-flop that controls the switching circuit to reverse polarity of the chrominance signal or carrier is, itself, controlled to start always in the correct polarity in those field intervals when it is operative.

Abstract: PUMP ASSEMBLY                 ABSTRACT OF THE DISCLOSURE         A rod-drawn pump for use in a well includes a housing and a rod reciprocating within the housing to move a plunger in a series of alternating upward strokes and downward strokes.  The plunger defines a pump chamber with a standing valve through which liquid from the well passes during the upward stroke of the plunger.  During the downward stroke, the liquid in the pump chamber passes through a traveling valve in the plunger and into a parti-cular cavity defined by the plunger and a third valve.          During the next upward stroke, the liquid in the particular cavity passes through the third valve to produce a column of the liquid which is eventually lifted from the well.          The third valve supports the column of the liquid during the next downward stroke so that the traveling valve in the plunger is open when it contacts the surface of the liquid in the pump chamber.  This inhibits gas and liquid pound during the downward stroke.  Portions of the rod at least partially define a passage which bypasses the third valve near the end of the downward stroke to substantially fill the particular cavity prior to the upward stroke.  This inhibits any gas or liquid pound which might otherwise result during the upward stroke.

Abstract: MOLTEN ADHESIVE DISPENSING DEVICE            Abstract of the Disclosure A  novel handle structure, and a novel heat exchanger structure, for a hand-held adhesive gun of the type adapted to discharge a heated thermoplastic adhesive through a discharge valve located in the gun's barrel.  In preferred form, the novel handle structure is positioned at the aft end of the gun's barrel, and has a longitudinal axis extending rearwardly of the gun's barrel and located at an acute angle relative to the longitudinal axis of the gun's barrel.  The gun's handle is positionable about the gun barrel's longitudinal axis between at least two operating locations, one being positioned 180° from the other.  A gun control switch is mounted interiorly of the handle, the switch being mechanically operated by the gun's trigger.  At least two ports are provided in the handle, one at the foot of the handle and the other adjacent the gun's barrel, the power cord that interconnects with the gun control switch being receivable into the handle through either port depending on the use orientation of the handle.  Also in preferred form, the novel heat exchanger includes a heat exchanger core fixed in location within a heater body's bore.  The heat exchanger core has spiral threads on the outer surface thereof, and the bore's surface has spiral threads thereon, too.  The heat exchanger core's threads are sized relative to the inlet bore's threads such that the core can be threaded into the bore, and such that the threads cooperate to define a spiral path about the core through the bore from one end to the other, thereby defining a spiral heat exchange path through the gun's heater body.  This novel heat exchanger is particularly adapted to elevate the temperature of the molten adhesive, just prior to dispensing it, above that temperature level at which the molten adhesive is supplied to the hand gun.

Abstract: ABSTRACT OF THE DISCLOSURE         Post type oil filled current transformers dissipate heat into the surrounding air.  However, the oil column being of small diameter does not circulate freely and does not transfer the heat sufficiently from the windings to the surface of the enclosures which is usually a porcelain insulator.  It is desirable to increase the flow of fluid withing the transformer. This increase can be obtained by introducing a flow controlling tube within the primary conductor which is vertical and hollow. The inserted tube defines two coaxial paths permitting flow of cool fluid down the central path within the tube and an upward flow of heated fluid in the outer annular path.

Abstract: ELECTRON PROJECTION MICROFABRICATION SYSTEM     Abstract of the Disclosure An electron beam image of a microcircuit pattern is pro-jected from an irradiated photocathode window to a resist-coated silicon wafer through two successive lens systems having field-containing regions which communicate through a small aperture in a common pole structure that otherwise shields these regions from each other.  The lens region in which the photocathode is located contains electrostatic and magnetic fields for accelerating the electrons and focusing the beam toward a crossover point in the aperture.  The region in which the wafer is positioned contains only a magnetic field to correct aberrations of the beam image.          The arrangement permits reduction of the image size.  Beam regis-tration detectors and deflecting devices are located near the aperture in the common pole structure.  Because it is isolated from objects located outside of its own lens region, the electro-static field is not perturbed by these detecting and deflecting devices or by variations in flatness of the wafer surface.  Back-scattered electrons emitted from the wafer cannot be driven by the electrostatic field onto parts of the wafer surface where no exposure to electron rays is desired.  The photocathode is protected from exposure to contaminants emitted by the wafer coating due to the restricted opening between the lens regions.
