Abstract: A B S T R A C T           The present invention relates to a tubular membrane apparatus, which may be made as a disposable unit, and the method of operation of that apparatus to achieve a transfer or exchange function.  More specifically, the present invention may be used to oxygenate blood, purify water, as a dialysis medium, and for other purposes.  The apparatus comprises a series of tubular membranes which are deformed at spaced intervals along their lengths to induce turbulent flow and secondary flow patterns which displace the stationary boundary layer which would otherwise exist adjacent to the inner surface of the tubular membrane such that the resistance to diffusion or exchange is substantially reduced.  Pulsatile flow of the fluid within the tubular membrane and/or the fluid surrounding the tubular membrane may be employed to enhance the effectiveness of the unit.  In a preferred embodiment, a liquid is flowed through the tubular membranes and a gaseous medium is caused to flow around the outer surface of the tubular membrane.

Abstract: SINGLE SIDED, HIGH DENSITY BUBBLE DOMAIN          PROPAGATION DEVICE     Abstract of the Disclosure A magnetic bubble domain propagation device which is single sided and can be used to move bubble domains in amorphous magnetic films.  The propagation structure is comprised of either one or two layers located on a single side of the amorphous magnetic medium.  Preferably, the propagation elements in each layer are contiguous to one another to provide maximum density.  In a preferred embodiment, the propagation elements are circular, but other geometries can be used.  The amorphous magnetic material is deposited over these underlayer propagation elements in order to create a change in the profile of the amorphous material.  This change in profile of the amorphous material acts as a restraining barrier to bubble domain movement, so that the bubble domains will move along the proper channel without drifting to other propagation channels, and will move from one propagation element to the next without merely idling at any of the propagation elements.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved liquid-dispensing nozzle and more specifically, an improved vapor recovery means for a nozzle com-prising a vapor collector surrounding a portion of the discharge spout in spaced relation thereto, one end of which is sealed to the upper portion of the nozzle housing or in proximity thereto; and at the other end of the vapor collector, a compressible cellular plastic material overlay on an equalizer means associated therewith.  When the discharge spout is inserted into, e. g., an automobile fillpipe, the compressible cellular plastic material forms a vapor seal with the upper end of the fillpipe whereby the vapors escaping from the fillpipe are directed into the interior chamber formed between the exterior of the discharge spout and the inside of the vapor collector thereby minimizing the escape of vapors to the atmosphere.  The vapors are then removed from this chamber.  Also disclosed is a sealing device for use with a liquid dispensing nozzle assembly including a nozzle housing with an elongated discharge spout and a flexible vapor collector surrounding the spout with one free end and the other end attached to the upper portion of the nozzle housing or in proximity thereto and provided with a means to recover vapor during delivery of liquid from the spout to a liquid receiver inlet including a mounting means affixed to the free end of the vapor collector, a sealant material means affixed to the free end of the vapor collector for contact with the receiver inlet, and an equalizer means affixed to the mounting means and interposed between the mounting means and the sealant material means so as to urge the sealant material means toward the receiver inlet when the spout is inserted in the receiver inlet.

Abstract: PNEUMATIC REGISTRATION APPARATUS                  Abstract of the Disclosure In a first embodiment a stop having a plurality of ports is connected to and covers an end of a rectangular sleeve.  In a region near the stop a narrow wall of the sleeve also has a plurality of ports.  A nozzle coupled to a pump provides a flow of air into the other end of the sleeve and the air exits through the ports.  With this arrangement, a rectangular sheet inserted into said other end of the sleeve is fluidly brought into registration with the narrow wall and stop.          As the sheet is brought into registration fluid injected or drawn through holes in a wide wall of the sleeve is used to force at least a part of the sheet against one of the wide walls and the resulting friction serves to brake the traveling sheet, thereby minimizing impact forces between the sheet, the narrow wall, and the stop.  In a second embodiment, similar to the first, the narrow wall and stop include internal projections against which an inserted sheet is registered.  In a third embodiment, similar to the first, a manifold is coupled to the ports and a vacuum pump is coupled to the manifold to accelerate registration.  In a fourth embodiment, similar to the third, the pumps are replaced with a reversible pump to register and discharge a sheet.

Abstract: Abstract of the Disclosure A process for the reduction of the nicotine content of tobacco by microbial treatment is disclosed.  Tobacco is subjected, under controlled conditions, to the action of a microorganism effective to degrade nicotine through a biochem-ical reaction in which, inter alia, 3-succinoylpyridine is formed.  Prior to subjecting the tobacco to the action of the microorganism, the tobacco is steamed to increase its moisture content.  Tobaccos with lowered nicotine content but no mass loss result from this process following short treatment periods. Also, tobacco treated in accordance with this process, when incorporated into a tobacco smoking product, produces a mild smoke, having a reduced nicotine content.  However, there is no loss of desirable flavor, taste and smoking properties.

Abstract: ELECTRONIC DIGITAL GOVERNOR     Abstract of the Disclosure The present invention relates to an electronic digital governor for controlling the RPM of an engine.  The governor is comprised of a clock generator which includes a clear pulse generator and a latch pulse generator.  A sensor is provided for receiving a train of pulses whose number per unit time is proportional to the RPM of the engine.  A counter is provided connected to the sensor for counting the number of pulses in the train of pulses.  The count is carried out between consecutive clear pulses fed to the counter from the clear pulse generator.  A latch is provided connected to the counter for storing a count accumulated between con-secutive clear pulses.  The latch is controlled by latch pulses from the latch pulse generator.  The time duration between consecutive clear pulses and consecutive latch pulses is the same and is equal to a predetermined time period T.  A comparator is provided which has a first input connected to the latch and a second input connected to a switch which is manually controllable to enter an upper bound RPM value.  The comparator compares the stored count in the latch with the upper bound RPM value and activates a relay if the stored value is greater than the upper bound RPM value.  An electromechanical device is provided which is controllable by the relay for controlling the RPM of the engine to reduce the RPM below the upper bound RPM value.
