Abstract: ABSTRACT           Insoluble gases, liquid and solid materials present as the disperse phase in a heterogeneous dis-persion are removed by contacting such dispersion with one side of a membrane in which the disperse phase is soluble and on which the disperse phase coalesces and contacting the other side of the mem-brane with a material which does not permeate or react with the membrane but which reacts with the disperse phase passing through the membrane.  The reaction product is such that it does not permeate the membrane.  In this manner the driving force for passage through the membrane by the diperse phase is maximized.

Abstract: PHOTOCONDUCTOR SUPPORT DRUM    FOR PHOTOCOPY MACHINE     Abstract Disclosed is a photocopy machine and a photoconductor support drum for use therein.  The photocopy machine is of the type which utilizes a reusable photoconductor and which electro-statically makes copies on plain paper.  The drum supports a photoconductor of undeterminate length around the peripheral sur-face of the drum and includes a supply spool of excess photo-conductor mounted within the drum and a take up spool for used photoconductor also mounted within the drum so that the portion of photoconductor positioned around the drum can be periodically replaced.  A portion of the drum surface is collapsible and means are provided at the location where the drum surface collapses to support the photoconductor in a flat plane to permit full frame, flash exposure of the photoconductor.  The collapsing of the drum surface and the supporting of the photoconductor in a flat plane are actuated in synchronism with rotation of the drum so that these operations take place when the collapsible portion of the drum is located at an imaging station as determined by the optical path of the photocopy machine.

Abstract: Abstract of the Disclosure Apparatus and method for detecting the presence, in an inspection area, of a marker tag having preselected properties.  Transfer of articles from a protected area can be monitored by coupling a marker tag with each article and by including an inspection area in all transfer paths.  In a theft detection system, the coupled marker tag can be removed or made in-operative in some manner for authorized withdrawal of an article from the protected area.  The marker tag is comprised of a small, thin strip of magne-tic material.  A time-varying magnetic field is provided for interacting with a marker tag located in the inspection area.  The magnetic field, which in-cludes components having frequencies f1 and f2, has a time-dependent spatial orientation which permits interaction with a marker tag having an arbitrary orientation in the inspection area.  The magnetic field components of fre-quency f2 produce changes in the magnetic properties of the marker tag, resulting in the generation of a signal having components of frequencies f1 ?2f2.  When the magnitude and phase of the signal having the component f1 + 2f2 falls within a range of values of magnitude and phase peculiar to the marker tag, an alarm is activated by signal detection apparatus.  The restric-ted nature of the signals producing an alarm effectively distinguishes a marker tag from signals produced by other objects in the inspection area.

Abstract: Abstract A device for monitoring the condition of a filter element, comprising a combined clamping nut and differential pressure indicator.  The body of the device is non-circular about an axis to facilitate its use as a wingnut, and has an outer surface and an inner surface through which passes an axial ori-fice, internally threaded to engage a threaded mounting rod.  A differential pressure responsive device of novel design, includ-inq a slack diaphram and an air-permeable translucent screen, is mounted in a further orifice in the outer surface for exposure of one side of the diaphram to the pressure outside the filter, and a passage in the body connects the further aperture with the inner surface to supply to the other side of the pressure respon-sive device the pressure within the filter.  The combination of such an arrangment with an air cleaner having a safety filter is also a part of the invention, as is the method of monitoring the filter conditions which the structure makes possible.

Abstract: WINDSHIELD HEATING DEVICE               ABSTRACT OF THE DISCLOSURE           A windshield heating device for a motor vehicle having a windshield with an upper portion and a lower portion is disclosed.  A plurality of electrically conductive grid lines are deposited on the lower portion of the windshield.          The grid lines are bonded to the windshield and are formed of a material which heats up when an electrical current is passed therethrough.  An instrument panel of the motor vehicle is mounted adjacent the lower portion of the windshield.  The instrument panel has openings therein in juxtaposition with the grid lines on the windshield.          Operation of a blower motor directs air over the grid lines when they are heated to cause a moving current of heated air to pass from the lower portion of the windshield to its upper portion.  This action defogs and/or defrosts the windshield.  The device is particularly useful when the motor vehicle is started initially as the vehicle's heating system has not had sufficient time to come up to proper temperature.

Abstract: Abstract of the Disclosure An article feeder for presenting spaced articles or groups of articles to a wrapping machine for wrapping the articles individually or in groups is described.  The warpping machine has a continuous drive mechanism driving the film feeding, wrapping, sealing and cut-off units of the machine.  The feeder employs a pickup conveyor having longitudinally spaced, retractable pushing dogs for feeding articles in spaced relation to the article receiving con-veyor of the wrapper.  The pickup conveyor is driven from the drive mechanism of the wrapper.  The feeder also in-cludes a metering conveyor for advancing a row of abutting articles toward the pickup conveyor and onto a deadplate be-tween the conveyors.  The metering conveyor is intermittent-ly driven by a clutch-brake and driven by a variable speed drive from the wrapping machine drive mechanism but at a slower speed than that of the pickup conveyor.  An accumulat-ing conveyor delivers articles from a supply to the meter-ing conveyor so that the articles are in a row in end-to-end abutment on the metering conveyor and the deadplate.  Control for the system includes a limit switch operated by a cam driven from the pickup conveyor so that one revolution of the cam represents travel of the pickup conveyor by a distance equal to the spacing between the dogs on that conveyor.  A retro-reflective scanner senses an edge of the leading article on the deadplate and cyclical operation of the limit switch, in response to the position of the pickup conveyor dogs, causes the metering conveyor to advance leading articles in the row across the deadplate to be picked up and accelerated by the pickup conveyor.  The scanner stops -la-the advance of articles by the metering conveyor when it senses an edge of an article on the deadplate, which is the leading article of the advancing row of articles.
