The invention is concerned with an improved individually replaceable insulation pack comprising a high temperature resistant thin flexible metallic sheet having a porous insulation blanket formed of interlaced ceramic fibers held against a side thereof and including a fine mesh of wire covering the surface of the blanket which is not adjacent to the sheet and holding the blanket against the sheet. The blanket does not contain a binder and is not bonded to the sheet.

An encapsulated flame retardant is made by a process including applying an organic silicon composition to a powder flame retardant. The organic silicon composition is an organofunctional-silane or a mixture of organofunctional silanes, an oligomeric organosiloxane or a mixture of oligomeric organosiloxanes, or a solvent-containing preparation based on monomeric organosilanes and/or on oligomeric organosiloxanes, or a preparation based on water-soluble organopolysiloxanes, or mixtures of any or a...

A device for classifying superfine material from continuously fed granular solids which has a charging chute feeding the material into a washing trough. The washing trough is formed by a conveyor belt, which is mounted on a machine frame. A part of the conveyor belt forms the washing trough downstream of the charging chute. Another part of the conveyor belt is arranged below the charging chute, and is elevated against the direction of flow of the charged material. The charging chute has a false ...

A device for washing out and classifying organic, clay-like and other impurities from gravel, comprising a charging chute for feeding material into a washing trough. The washing trough comprises a conveyor belt designed to move in a direction perpendicular to the direction of the flow of material and a plurality of shower devices designed to act against the direction of travel of the belt. The conveyor belt is supported by a series of support rollers and tension rollers. These support rollers an...

The present invention is directed to a method of preparing a substrate to improve the adherence of a metallic coating to the substrate and the product thereof. More particularly, a method of manufactiring a molded circuit board and unique circuit board produced thereby, is disclosed. A molding compound, such as an epoxy resin is blended with a plating additive, such as calcium carbonate that is relatively inert to the molding compound. The blended mix can then be molded into a desired shape whic...

A fire-retardant laminated plastic material which includes a woven barrier layer of high-density polyethylene sandwiched between outer layers of low-density polyethylene material in which a polymer of antimony trioxide is incorporated in the outer layers. Additional outer layers may be laminated to the structure to serve as a carrier of pigments or to increase abrasion resistance of the structure.

A laminated thermal insulation sheeting for covering ducts and pipes wrapped up by a thermal insulator such as glass wool and rock wool, includes an aluminum sheet and a metal network disposed on and over a surface of the aluminum sheet. A substantially transparent film of synthetic resin is placed on the metal network and has portions bonded to the surface of the aluminum sheet through interstices in the metal network. The aluminum sheet comprises aluminum foil or an aluminum-metallized film of...

Disclosed is an incombustible composition for a fire door/wall, the fire door/wall using the incombustible composition, and a method of producing the fire door/wall. The incombustible composition includes 1 to 80 wt % of organic or inorganic fiber, 1 to 80 wt % of fly ash or bottom ash, 1 to 80 wt % of fire-proofing agent, 1 to 30 wt % of curing fire-retardant resin, and 1 to 40 wt % of incombustible hollow filler. Furthermore, the method includes providing the incombustible composition, mixing ...

A fire barrier fabric further comprising a multilayer fabric having at least two layers, including an outside layer and a fire barrier layer; wherein the fire barrier layer provides flame-retardant and/or flame-resistant properties to the entire fabric without requiring fabric coatings or treatments to provide any contribution to flame retardance or resistance, wherein additional layers may include a filler layer, and wherein the fabric is applied to articles, such as upholstered articles and ma...

A textile product with enhanced flame and/or smoke retardant properties and a method of forming the same is disclosed. The textile product is comprised of a textile material having a primary layer or backing with intumescent particles coated, sprayed, sprinkled, or otherwise applied to the upper surface thereof. Additionally or alternatively, the particles may be incorporated into the tufting primary or backing. The intumescent particles may also be complexed with additional agents, such as anti...
