Abstract: Abstract A self-exposing imaging element is disclosed comprising a support member, a light sensitive layer, and a layer containing reagents which will chemically react in a chemiluminescent reaction to produce light which exposes the light sensitive layer when in contact with an original.  Reagents in the light generating layer are physically or chemically segregated prior to exposure to prevent reaction, for example, by encapsulation of one of the reactants, the reaction solvent, or a catalyst.  To copy the self-exposing imaging element is placed in contact with an original, the light generating layer is activated by causing the reactants to mix or introducing the reaction solvent or catalyst and the radiant energy generated produces an image of the original in the radiation sensitive layer by reflex imaging or direct transmission imaging.

Abstract: ABSTRACT         Tissue dispensing system for dispensing a stack of interleaved facial tissues from a wall mounted type dispensing cabinet employs a plastic overwrap package of facial tissues having a perforated opening which automatically adheres a front face of the package to a slot in the cabinet to provide improved tissue dispensing.  As each tissue is dispensed, tensile forces are applied to the front face of the package along defined lines by the edges of the tissue passing past the corners of the opening in the package causing the front face of the package to bend into a truncated, hip-roof shaped structure having the truncated end depending from the slot in the cabinet.  The tensile forces on the front face cause compressive forces to be applied about a perimeter region situated between the outer extremes of the front face and the outer extremes of a back face of the package in a sense opposing movement of the stack of tissues away from the back face of the package as the stack of tissue diminishes and in a manner preventing collapse of the plastic package during dispensing of the tissues.

Abstract: Docket M-295 PRINTING APPARATUS            Abstract of the Disclosure There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an  operating lever.    The operating lever is coupled to a slide which drives a feed finger and cam means for actuating an inker.  The travel of the feed finger is selectively variable by changing the position of the pivot on which the lever is mounted.  The cam means is part of a lost-motion connection which couples the slide to the inker.  As the operating lever is cammed in one direction to move the feed finger forward,  the inker is moved into and out of inking cooperation with the print head assembly.  Because of the lost-motion connection adjustment of the pivot does not affect the length of travel of the inker.  When the inker is in inking position the inker is supported at both sides of the platen thereby leaving the platen accessible during threading of the apparatus with the web of record members.  The print head assembly includes a pair of print heads, each print head having at least one series of rotatably mounted drive wheels and a support.  A plurality of printing bands having different printing elements are trained  about the support and respective drive wheels.  Each support of each print head is adjustable by exerting forces at opposite ends of the support so that all the printing elements at the support are disposed in a common plane parallel to the platen.  The Docket M-295 print heads are rigidly interconnected by plates.  Set screws threadably received by one of the plates are accessible from about the print head and act on adjusting plates which exert forces at opposite ends of the respective supports.

Abstract: ABSTRACT OF THE INVENTION    Relatively long microfilaments made from a low heat conductivity glass composition are described.  The micro-filaments are used to make insulation and/or filler materials.    The microfilaments are made by forming a liquid film of molten glass across a coaxial blowing nozzle 5, applying a blowing gas 10 at a positive pressure on the inner surface of the glass film to blow the film and form an elongated hollow tube or cylinder 12 of molten glass.    Means are provided for forming a thinned wall or weakened portion of the forming elongated tube or cylinder.          A transverse jet 13 is used to direct an entraining fluid 14 over and around the blowing nozzle 5 at an angle to the axis of the blowing nozzle.  The entraining fluid 14 as it passes over and around the blowing nozzle 5 fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle and produces a laminar flow of entraining fluid in the vicinity of the forming elongated tube or cylinder.          The continued movement of the entraining fluid 14 over the elongated cylinder 12 produces asymmetric fluid drag forces on the cylinder, and at the thinned walled or weakened portion longitudinally breaks the cylinder to form a multiplicity of microfilaments, and detaches the microfilaments from the elongated cylinder and from the coaxial blowing nozzle and the detached filaments are carried away from the blowing nozzle.

Abstract: SPECIFICATION     Title of the Invention METHOD FOR THE PURIFICATION OF PROPYLENE POLYMERS    Abstract Disclosed is a method fox the purification of propylene polymers which comprises bringing a propylene polymer containing volatile components into contact with a gas consisting mainly of propylene at a temper-ature lower than the melting point of the polymer, whereby the volatile components are removed from the propylene polymer.            A  process gas obtained by evaporating the reaction medium contained in a slurry resulting from bulk polymerization using propylene itself as the reaction medium or a process gas separated and recovered from a polymerization mixture resulting from vapor phase polymerization is suitable for use in the practice of the present invention, because its dew point is low-enough for drying purposes and it can be recycled in large amounts.       The method of the present invention permits the volatile components contained in the polymer to be removed to substantially the same extent as is attainable by the conventional drying method using a large amount of nitrogen gas.  Thus, the present method has very great economic advantages over the conventional one.

Abstract: ABSTRACT OF THE DISCLOSURE           An input shaft of a press feed is rotated at a preselected speed and is drivingly connected to a cam that rotates with the input shaft.  Continuous rotation of the cam is converted to oscillating rotational movement of a cam follower through a preselected angle of rotation.  The cam follower is nonrotatably connected to an output shaft that is connected by an adjustable linkage mechanism through a pair of meshing gears to a driven feed roll.  The oscillating rotational movement of the output shaft is transmitted to the driven feed roll to advance the driven feed roll in contact with stock material through a preselected degree of rotation corresponding to a preselected feed length of the stock material to the press.  A material guide assembly provides a preselected spacing so that the feed of stock material of a preselected thickness is maintained along a substantially linear path.  The guide assembly has a movable guide spaced from a stationary guide with the stock material fed between them.
