Title: Novolac based epoxy resin curing agents for use in solvent systems
Inventor: DEGOOYER WILLIAM J
IPC: C08G59/56
Filed: 1985-08-13
Granted: 1989-05-30
Abstract: (h)  Abstract of Disclosure The instant invention is an epoxy resin curing agent based upon an epoxy novolac containing, on the average, between about 3 and about 7.5 epoxy groups per molecule, in which substantially all of the epoxide groups are reacted with a polyamine wherein each primary amine hydrogen in the resulting reaction product is further reacted with a monoepoxide. The resulting epoxy resin curing agent may be used in a solvent based system to cure epoxy resins under low temperature curing conditions.

Abstract: ABSTRACT OF TIE DISCLOSURE A drying apparatus for sheets of material.  The apparatus includes a drying chamber through which a sheet of material which is to be dried is conveyed, and in which the sheet of material is contacted by flowing drying gas.  The apparatus also includes a feed line for supplying drying gas to the apparatus, a heater for heating the drying gas, and a withdrawal line for withdrawing the drying gas from the apparatus.  The drying chamber comprises cup-shaped and rounded-off wall elements which are easily detachably connected to one another.  The wall elements have a smooth inner surface.  A jacket is disposed around the drying chamber.  An intermediate space is defined between the inner surface of the jacket and the outer surface of the wall elements of the drying chamber.  Drying gas is introduced through the feed line into the intermediate space.  After this drying gas has been heated in the heater, it flows through the drying chamber.  A pressure gradient is maintained between the intermediate space, the drying space, and the atmosphere, with the pressure being lowest in said drying chamber means.  The hot drying gas in the drying chamber gives off at least some of its heat to the drying gas in the inter-mediate space.  The used drying gas leaves the drying chamber via the with-drawal line.

Abstract: ABSTRACT OF THE DISCLOSURE         Provided is an optical data storage medium comprising an organic information layer having a reflectivity of at least 20%.  Moreover, the material of which the information layer is comprised exhibits good amorphous film forming characteristics and is readily solvent castable.  The medium can also be erasable.         The information layer comprises a chromophore composition which can be comprised of a chromophore or chromophore/polymer combination.  Its high reflectivity elimi-nates the need for a metallic reflective layer in addition to the information layer, or the need for any anti-reflective structure.  Thus, the structure of the medium is simplified.  As well, the amorphous film-forming characteristics of the chromo-phore composition allow for ready manufacture of the medium.

Abstract: THE ABSTRACT OF THE DISCLOSURE           An improved apparatus is provided herein for manufacturing an elastomer-coated  bias-fabric.  The apparatus includes means for moving a bias-cut fabric in a generally horizontal path of travel, means for immersing the fabric in an elastomeric composition as it moves along the path of travel, so as to impregnate the yarn bundles in the fabric with the elastomeric composition  means for transversely stretching the fabric and maintaining the fabric in a stretched condition, such means being positioned downstream of the means for immersing the fabric and being operative as the fabric moves along the path of travel and as the fabric is coated with an elastomeric composition and the elastomeric composition is dried, a first applicator positioned beneath and extending across the path of travel for continuously applying a layer of an elastomeric composition to the bottom surface of the fabric as the fabric moves along the path of travel, a second applicator positioned above and extending across the path of travel for continuously applying a layer of an elastomeric composition to the top surface of the fabric as it moves along the path of travel, a first scraper positioned beneath the path of travel and downstream of the first and second applicators and extending across the path of travel for continuously smoothing the layer of elastomeric composition on the bottom surface of the fabric to the desired thickness and removing excess composition, and a first dryer positioned immediately downstream of the first scraper means for drying the coated fabric.  The improvement resides in the provision of the following additional elements:  a third applicator positioned downstream of the first dryer and extending across the path of travel of the fabric for continuouly applying a layer of a tackified elastomeric composition to only one surface of the fabric in a non-pressurized manner as the fabric moves along said path of travel; a second scraper positioned beneath the path of travel of the fabric and downstream of the third applicator for continuously smoothing the layer of tackified-latex composition on the bottom surface of the coated fabric to the desired thickness and for removing excess composition; and means for collecting the coated fabric.

Abstract: ABSTRACT          A mixer circuit capable of receiving two local oscilla-tion signals which is free from conversion characteristic deterioration, which suppresses leakage of local oscillation signal and which does not require a large circuit space is described.          The mixer circuit has a main line for receiving an input microwave signal at its one edge and a mixer diode for mixing the input microwave signal with either of first and second local oscillation signals.  One of the terminals of the mixer diode is coupled to the other edge of the mixer line and a coupling line is coupled to the other terminal of the mixer diode.  The coupling line has substantially 1/4 wavelength with respect to the input microwave signal.  Two distribution-coupling type bandpass filters are dis-posed along both sides of the coupling line for receiving the first and second local oscillation signals, respectively.  A delivering line is coupled to the edge of the coupling line at which the mixer diode is connected for delivering an intermediate frequency signal.

Abstract: ABSTRACT          A holder for an electret microphone of the type having a front acoustic aperture and peripheral acoustic apertures is made of insulating material and includes a first sleeve portion of a diameter to receive the microphone snugly and a second sleeve portion of larger diameter.  An internal stop limits the extent to which the microphone can be inserted such that the rear portion of the microphone projects into the second sleeve portion.          Through holes in the second sleeve portion provide an acoustic passage to the peripheral acoustic apertures.  The internal stop is in one embodiment formed by an apertured web.  In another embodiment an internal shoulder forms the stop but in that embodi-ment too an apertured web is provided.  A concentric small cylinder extends from the web in that case and terminates short of the shoulder.  In either embodiment, a rectangular plate is molded with the sleeves and this forms the cover of a microphone enclosure.          The invention retains or enhances the acoustic response of con-ventional mounting systems while providing protection against electrostatic discharge.
