摘要:
A portable cart with a noncombustible heat and fire resistant panel of calcium silicate for separating compressed oxygen cylinders from compressed fuel gas cylinders where the calcium silicate panel has a fire resistance rating greater than one half hour and spans the entire height and width between adjacent oxygen and fuel gas cylinders.
摘要:
An asbestos-free insulating material suitable for use in molten metal casting is disclosed. The material is made from a mixture comprising lime, siliceous component, wollastonite, inorganic fiber and pitch based graphite fiber. The mixture is mixed with water to form a slurry, shaped, heated in the presence of steam, and dried to remove free water.
摘要:
Rigid clips, having an upper hanger portion and a lower channel formed to grasp the common elongate protrusions formed along the top edge of extruded vinyl siding, support the siding while permitting it to expand and contract freely with changes in temperature.
摘要:
An asbestos free, calcium silicate insulating material, suitable for use in applications where a tough, fire resistant, heat insulating, electrical insulating, and corrosion resistant material is desirable. The calcium silicate insulating material is produced by combining Portland cement, blast furnace slag cement, a siliceous component, wollastonite and organic fibrous material in the presence of water to form a slurry. The slurry is then placed under steam pressure, to react the portland cement, blast furnace slag cement, siliceous component and water, dried, and heat treated if necessary.
摘要:
A pneumatically operated staple gun with an adjustably spaced away elongate guide shoe allows control, with fine adjustment, of depth of penetration of staples, when stapling, through nailing slots of vinyl siding, into thick low density insulating boards. Shoe includes slot locating means in one embodiment.
摘要:
An asbestos free, calcium silicate insulating material suitable for use in the casting of molten non-ferrous metals, and suitable for use in applications where a fire resistant, heat insulating, electrical insulating, and corrosion resistant material is desirable. The calcium silicate insulating material is peoduced by combining lime, a siliceous component, alumina silica microspheres, wollastonite and organic fibrous material in the presence of water to form a slurry. The slurry is then placed under steam pressure, to react the lime, siliceous component and water, dried, and heat treated if necessary.
