Patent CA-1052612-A (CA)
Inventor: NACCI GEORGE R
IPC: G03F7/26
Filed: 1975-03-17
Granted: 1979-04-17
Abstract: ABSTRACT OF THE DISCLOSURE              Described are photopolymerizable compositions containing (a) an ethylenically unsaturated compound, (b) about 3-95% by weight of an organic polymeric binder, (c) about 0.1-5% by weight of a nitroso dimer which is a noninhibitor of free-radical polymerization but ther-mally dissociates to nitroso monomer which is an inhibitor of free-radical polymeri?ation, and (d) about 0.1-2% by weight of an organic, radiation-sen-sitive, free-radical generating system. Positive-working, contour images are formed by applying a layer of this composition to a substrate, imagewise exposing the photopolymerizable layer to actinic radiation through an image-bearing transparency at about 20-65°C, whereby free-radicals are consumed by nitroso monomer, deactivating the nitroso dimer inhibitor system, reexposing at least the unex-posed portion of the photopolymerizable layer to actinic radiation while continuing to maintain the nitroso dimer inhibitor system in the deactivated state, and developing the resulting image.  The nitroso dimer inhibitor system may be deactivated by cooling the photopolymerizable layer to below about 10°C, and reexposing the layer to radiation that does not appreciably dissociate the nitroso dimer at a temperature below about 10°C, or by heating the photopolymerizable layer at about 80-150°C thereby destroying the nitroso dimer inhibitor system, and reexposing the layer to actinic radiation at about 20-60°C.

Abstract: ABSTRACT OF THE DISCLOSURE           Herein are disclosed a method and apparatus whereby dispersed matter in the form of finely-divided particles, and/or in the form of molecular species such as molecules, atoms and radicals, are separated from a gaseous or liquid medium. A fluid medium containing dispersed matter is subjected to a field of a corona discharge from a first electrode (hereinafter referred to as a "separating electrode") which is pervious to the passage of the fluid medium and dispersed matter, whereby particles are charged if not already charged, and molecular species are ionized if not already ionized, in the same electrical polarity as that of the charge on the separating electrode, and the dispersed matter is selectively repelled by the influence of the field and electrode, and a fluid medium containing a consequently-reduced concentration of the dispersed matter is passed through the separating electrode and collected. The charged particles and/or ionized molecular species preferably are exposed to a second electrode (hereinafter referred to as a "collecting electrode"), preferably but not necessarily grounded, in order to facilitate the collection of the selectively-repelled dispersed matter.

Abstract: ABSTRACT OF THE DISCLOSURE A fabric is coated by spreading a one-package liquid mixture of a polyamine carbamate and a free isocyanate group - containing reaction product of a polyisocyanate with a polyhydroxy material onto a release surface, heating the coating at the decomposition temperature of the carbamate to cause gelling and partial foaming, placing a woven or nonwoven fabric over the gelled coating, heating the resulting laminate to complete the foaming and the cure, and finally stripping the release surface from the coated fabric.  Alternatively, the coat-ing may be fully foamed and cured before applying the fabric and a conventional adhesive is employed to secure said coating to the fabric.  An unfoamed conven-tional skin coating may also be applied to the release surface before the foam-ing material is spread onto it.  Direct coating of suitable fabric substrates can also be carried out.

Abstract: MAGNETIC VIDEO RECORDING AND REPRODUCING APPARATUS        ABSTRACT OF THE INVENTION         In a cassette casing having a supply reel, a take-up reel and a hollow cylindrical member, a magnetic tape is fed from the supply reel and, after having been spirally wound around the intermediate hollow cyndrical member, wound on the take-up reel.  To this end, the hollow cylindrical member is formed with a spiral guide rib with a pitch substantially equal to the width of the magnetic tape and threadedly or screw-wisely received in an opening formed in the bottom plate of the cassette casing.  When the cassette casing is placed in the position ready for operation within a video recording and re-producing apparatus, a rotatable magnetic head drum having a magnetic head is inserted into the cylindrical member.  There-after, the cylindrical member is moved outwardly from the cassette casing by rotating it through a driving apparatus, whereby the magnetic tape wound around the cylindrical member is progressively transferred onto the head drum to the position for recording or reproducing.  When the cassette casing is to be removed from the apparatus, the hollow cylindrical member is rotated in the reverse direction to be inserted into the casette casing by virtue of the threaded engagement with the opening formed in the bottom plate of the cassette casing.  Then, the magnetic tape is transferred back to the cylindrical member from the magnetic head-drum.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus for selectively transferring magnetic toner from a reservoir to the imaged areas of a copy web.  The reservoir is used to develop a donor web in which a multiplicity of microfields have been recorded.  The donor web is subsequently passed into non-contacting proximity to a copy web having a latent magnetic image thereon.  The toner is selectively attracted to the stronger magnetic forces in the imaged areas of the copy web and remains on the donor web in the non-imaged areas.  Another aspect of the invention provides for the neutralization of the donor web microfields prior to the toner transfer to enhance the development process.
