Title: Method of bonding synthetic resin fastener having fusion heat to flat film
Inventor: YANO MITSURU
IPC: B29D5/00
Filed: 1982-05-27
Granted: 1986-01-21
Abstract: ABSTRACT OF THE DISCLOSURE         A method of and apparatus for fusion bonding a continuous synthetic thermoplastic resin fastener strip having a fastener profile portion and a base portion opposite the profile, to a continuous film substrate.  The substrate is advanced continuously through a bonding zone.  Continuous direct transit of the fastener strip is effected from thermoplastic extruder downwardly through a short distance to the bonding zone, so that in the short transit distance the fastener strip will retain substantial residual thermoplastic fusion temperature.          The fastener profile portion is chilled while the strip is in transit to the bonding zone, solidified and stabilized, but the base portion, is left at sufficient residual fusion temperature to remain thermoplastic to the bonding zone where assembly of the strip and substrate is effected by fusion bonding of the base portion to the substrate.  An annular rotary heating surface may be applied to a narrow locally limited longitudinal area of the substrate for supplying to such area fusion promoting heat in the bonding zone, such area being aligned with the fastener strip in the assembly.  The longitudinal area may be stretched by the rotary heating surface.

Abstract: ABSTRACT            PROCESS FOR THE PRODUCTION OF A PEROXY COMPOUND       In the present invention, hydrated magnesium salts of the carboxylate group in certain aromatic or olefinically unsaturated peroxyacids such as monperoxyphthalic acid or monoperoxymaleic acid are made by reacting the corresponding anhydride with aqueous hydrogen peroxide and a magnesium base, in the absence of a significant amount of free iron. By so doing, the process avoids the use of non-aqueous solvvents such as ethyl acetate.   Solid product can be obtained by using no more than enough hydrogen peroxide and water for solely a damp product to be obtained or by crystallisation from an aqueous solution, preferably with recycle of the mother liquor.  Preferably the reaction temperature is maintained at 5 to 25°C, employing 1.8 to 2.2 moles anhydride per mole of magnesium base, and 0.95 to 1.2 moles of hydrogen peroxide per mole of anhydride.       The product can be used as a bleach and as a disinfectant.

Abstract: FUEL ADMIXTURE FOR A CATALYTIC COMBUSTOR            Abstract of the Disclosure Disclosed is a catalytic combustor and systems for the boilerless stoichiometric production of a working fluid such as steam from a fuel-mixture comprised of a carbonaceous fuel and a diluent such as water mixed in a thermally self-extinguishing mass ratio.  Production of the steam is by a controlled substantially stoichiometric process utilizing a combustor to provide steam over a wide range of heat release rates, temperatures and pressures for steam flooding an oil bearing formation.  Even though formation characteristics change during a steam flooding operation, output steam of the combustor may be kept at a constant heat release rate by dividing the total amount of water passing through combustor between a first portion which is included in the fuel-mixture and a second portion which is injected into the heated products of combustion. In this way, the space velocity of the fluid stream passing through the combustor catalyst may be kept within operational limits of the catalyst while maintaining stoichiometric combustion.  When necessary, preheating of at least one of the components of the mixture burned in the catalyst is provided by a portion of the heat of combustion.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention presents a method for the production of sulphur in granular form as well as a device for the carrying out of the invention, by which sulphur can be obtained in granular form in more economic and simpler way, as an end product, having a high breaking strength with a strongly reduced dust buildup during the manufacturing process, as well as a more uniform grain size. This is made possible by providing that the sulphur is first brought to a temperature over 150°C, whereby it reaches viscosity which makes it possible to bring the sulphur to a drop-shaped particle form slowly deposited onto a cooled surface.          By cooling on a cooled surface or a belt cooler in at least two steps, due to a more suitable value of the cooling temperatures, a too rapid cooling and thus undercooling and liquid discharge of the sulphur can be avoided. As a device for carrying out the method, a rotary drop extrusion mold is provided which does not require any great structural demands and enables the granulation of the sulphur according to the method of the present invention in simpler way.

Abstract: METHOD FOR COATING OPTICAL TRANSMISSION GLASS FIBERS          Abstract of the Disclosure A method  and  apparatus  for  coating  optical transmission glass fibers with a resinous composition.          A vessel is provided through which a glass fiber is drawn.  While it is being drawn through the vessel, the fiber is spun, and a resin coating is applied.  In order to maintain the air pressure within the vessel fairly constant,  an exhaust vent is provided through which excess particles of the resinous composition may escape.  Turbulence  is  thus  substantially  reduced preventing the fiber from swinging and allowing the particles  to  be  sprayed  smoothly.   Further,  the particles may be electrically charged so that they are both attracted to  the  optical fiber  and repel one another during flight.  The invention employs both of these features to produce a uniform coat on an optical transmission glass fiber.
