Abstract:
The fiber reinforced hollow microspheres (17) are made by forming a liquid film of a fiber and molten or liquid film forming material composition across a coaxial blowing nozzle (5), applying a blowing gas (10) at a positive pressure on the inner surface of the liquid film to blow the film and form an elongated cylinder-shaped liquid film (12) of molten film forming material. A transverse jet (13) is used to direct an inert entraining fluid (14) over and around the blowing nozzle (5) at an angle to the axis of the blowing nozzle. Quench nozzles (18) are disposed below and on either side of the blowing nozzle (5) and direct cooling fluid (19) at and into contact with the fiber and molten film forming material microspheres (17) to rapidly cool and solidify the molten fiber forming material to form a hard, smooth fiber reinforced hollow microsphere (17).
Abstract:
Decorative, inlaid sheet materials which incorporate a matrix layer of discreet, low aspect ratio resinous particles embedded in a resinous coating. The use of printed patterns which are visible beneath the adhesive matrix containing the particles constitutes a preferred embodiment of the invention. The sheet materials of this invention are real through-patterned inlaids which do not lose their pattern due to wear in use, and which offer unique design advantages and flexibility, as well as superior properties.
Abstract:
An electrical insulation material comprising a B-staged hydrocarbon elastomer impregnated mica paper (1) combined with a glass scrim (2) and a plurality of polymeric sealing layers (3) (4) (5) provides electrical insulation tape with superior properties. The conformable mica insulation tape is characterized by high flexibility high conformability, and improved electrical insulating and stability properties. Upon wrapping to such things as electrical coils and subsequently curing, the tape provides excellent electrical properties and high heat resistance. The tape is sealable and especially adapted to stringent, for example, high temperature, environments.
Abstract:
Solid lignocellulosic material is bonded together by heating and pressing at a natural wood pH by reacting sugars, starches or both in the presence of a catalyst capable of catalyzing transformation of the sugars and starches into a solid, insoluble in water, and an alkaline buffering agent if needed, for example to make waterproof plywood or composite products from particulate wood without hydrolytic degradation of the wood.
Abstract:
A process for manufacturing individual layered structures (12) and the individual layered structures (12) produced. There is provided a continuous web layered structure (14) having cutting lines across the width. The continuous web layered structure (14) contains particulate materials (6, 7, 9) between two containing layers (1, 2). One of the two containing layers (1, 2) is permeable to liquids. A thermoplastic material (16), in liquid form, is applied to the continuous web layered structure (14) over at least part of the cutting lines. The thermopalstic material (16) will join the two containing layers (1, 2) at each point of application. The thermoplastic material (16) is allowed to set. The continuous web layered structure (14) is cut along the cutting lines within the applied thermoplastic material (16) to provide individual layered structures (12).

Abstract:
An orientable in situ expandable layer (139) comprising: (a) a blend of incompatible, in situ-expandable thermoplastic particles and a thermosensitive matrix resin for the in situ-expandable thermoplastic particles which blend has the capacity of expansion in height, width and length directions, and (b) other insoluble and matrix-resin incompatible solid particles (141) uniformly incorporating throughout the resin matrix, which other insoluble and matrix-resin incompatible solid particles (141) have: (i) an aspect ratio of greater than 1, that defines a longitudinal axis (length) of the particles which longitudinal axis is not greater than about one inch, and (ii) thermal stability at the temperature of expansion of the resin and insolubility in the resin, and (iii) an orientation in the thermosettable resin of their length in one or two direction. Moldable compositions and methods of making the compositions and molded articles from the compositions are disclosed.
Abstract:
Evacuated microspheres (10) and insulating materials constructed from such microspheres (32) provide insulation and reduce heat transfer through radiation, conduction and convection. Additionally, an infrared reflective coating (16) is provided on a microsphere surface to reduce radiant heat transfer. A protective exterior coating (18) is also provided to protect an exteriorly applied infrared reflective coating on such a microsphere. The evacuated microspheres are used in elastomeric roof coatings or exterior paints.
Abstract:
A toner receiver sheet having excellent adhesion to toner particles, as well as optical clarity and physical properties that reduce or eliminate sheet feeding problems in automatic copying machines, is prepared by coating on each side of a transparent polymeric support (10) a thin toner-receiving surface layer (11, 12) of a dilute aqueous colloidal solution consisting of an acrylic polymer, an electrically conductive organic compound and a small concentration of transparent, non-light scattering polysiloxane beads (13, 14, 15, 16). The thin toner-receiving surface layer (11, 12) is dried and cured to form on the support a water-insoluble acrylic layer less than 2 microns thick and affixed thereto a distribution of widely spaced apart transparent polysiloxane beads having a diameter of 10 to 15 microns (13, 14, 15, 16).
