Abstract: A method is disclosed for the determination of the thermal conductivity of low density matted inorganic fiber insulating bodies by transmission of visible light through such bodies. The method is particularly applicable to fiber glass bodies. Densities must be such that radiation is the principal heat transfer mechanism.

Abstract: A process is described for the formation of fibrous calcium sulfate hemihydrate, the fibers thereof having specified dimensions, wherein a dilute aqueous suspension of gypsum and, if desired, a crystal habit modifier is first formed. The gypsum in the suspension is then converted into fibrous hemihydrate by reaction in the presence of saturated steam at 120.degree. to 155.degree.C for 0.5 to 2.5 hours.

Abstract: A sealing cartridge for rotating shafts is described, comprising a housing, an inwardly disposed compressed mechanical packing, and an outwardly disposed radial pressure lip seal. The two types of sealing elements cooperate to permit adequate lubrication of the shaft while yet obtaining complete containment of the functional fluid.

Abstract: Method of producing distinctive thermal reaction products of combinations of asbestos fibers with vinyl-containing organic polymer material having improved and unique, lasting physical and electrical insulating properties among others, by means of heating the combined asbestos fiber with vinyl-containing organic polymeric material in an oxidizing atmosphere, and the resultant enhanced asbestos-polymeric material heat reaction products and electrical insulating materials provided thereby.

Abstract: Fibrous mat, e.g. glass fiber, having a sheet facing on one face is wound in continuous lengths with minimum tension, compression, shear and working during the winding and with a large open center. The coils are compressed by a straight line compression generally normal to the major face of the mat and packaged with greater compression than heretofore acceptable in view of the recovery of insulation thickness upon installation. Nearly complete recovery is experienced. Further, stresses on the coiled material during compression and packaging are insufficient to destroy the longitudinal integrity even when it is skip chopped in a manner which separates more readily than prior skip chopped strip.

Abstract: A method is disclosed for the formation of a siliceous thermal insulation, usable to 2000.degree. F., from calcined and natural diatomite powders, hydrated lime, clay and synthetic fibers. The shaped insulating product obtained is also disclosed.

Abstract: An aesthetically pleasing texture is imparted to wet-laid fibrous mats by distributing a layer of solid expanded particles of synthetic thermoplastic resinous foamed material on the upper surface of the mat. The particles are then pressed into the wet lap to embed the particles in the fibrous material and the wet lap is subsequently heated to reduce the volume of the particles and leave depressions in the surface which result in a unique random surface texture.

Abstract: Low abrasion, high strength friction materials are described, containing rubber binder, inorganic filler, fiber, and not more than 1% by volume of lead and lead oxide. Organic fillers and phenolic resins may also be present. The materials find particular use as brake shoes for railroad rolling stock which uses wheels of relatively soft steel.

Abstract: The present invention provides an improved process for increasing the chill haze stability of aqueous liquids derived from fruits and vegetables, (e.g., beer, wine, fruit juices, vinegar, etc.) by using one or more haze control agents in a precoat or after precoat layer in the filter media used to filter the liquid and by adding one or more haze control agents as a body feed upstream of the filter. In a preferred embodiment one or more haze control agents are also added in ruh storage at a time in the process significantly before the filtration step. This improved process permits the beverage to be packaged immediately after filtration, thus eliminating the time consuming and space consuming storage following filtration normally required by conventional chill haze control techniques.

Abstract: Treatment of asbestos fiber with a first coating of from about 0.1 to 5 weight percent of a phosphate, or acid thereof, and subsequent addition of a nonfoaming anionic dispersant on the coated fiber produces an asbestos fiber product that possesses improved filtration properties. This treated asbestos improves the production rate of articles from cement slurries or pastes containing asbestos.

Abstract: A portable charcoal igniter device is disclosed, consisting of an upright hollow body with a plurality of air intake openings disposed at the lower end thereof. The device is composed of inorganic fibers, binder, and an optional filler.

Abstract: A repacking kit for replacement of fluid seals for devices such as pumps is described. The kit comprises a plurality of preformed, oversized circular split rings having a specified configuration. The rings assume a helical shape around the shaft to be sealed and each is cut to size in a single step. The kit is prepacked in a quantity (generally five rings) predetermined to be that required for complete replacement of the packing of a single pump.

Abstract: A friction disc comprises continuous longitudinally co-extensive generally parallel glass strands wound spirally in the plane of the disc; short, generally parallel glass strands extending normal to the plane of the disc along said spiral; non-ferrous metal chips or wires; and a heat curable cement binding said glass strands and non-ferrous metal chips or wires together. The friction disc is made by forming a glass fabric with warp rovings of continuous parallel glass strands and fill rovings of continuous parallel glass strands; impregnating the fabric with a heat curable cement; winding the glass fabric onto a mandrel to form a spirally wrapped cylinder; slicing the cylinder into disc preforms; and molding the disc preforms under heat and pressure. Either non-ferrous metal wires are included in the fabric or non-ferrous metal chips are deposited on the fabric prior to wrapping the fabric onto the mandrel.

Abstract: An inorganic composition useful as material for Lehr rolls at temperatures above 500.degree.C consists essentially of 15-45% chrysotile asbestos, 40-75% talc component and 2-35% inorganic binder. The composition is also used in manufacturing millboard by forming a water slurry of said composition and transferring said slurry to a rotating screen cylinder, then to a moving belt and then to a rotating drum upon which layers of said slurry accumulate upon each other and are thereafter slit, dried and formed into a flat sheet.

Abstract: A thermal insulation composition is described which is dry, free-flowing, granular, and has a thermal conductivity approximately that of dry still air. The composition contains two granular siliceous materials and a granular opacifier. The first siliceous material is coarser and denser, and provides the principal bulk density of the final mixture. The second siliceous material is quite fine, and provides the principal free-flowing properties of the mixture. In a preferred embodiment a third siliceous material is also included to increase the overall surface area.

Abstract: A simple and rapid test, and an apparatus for use therein, is described for measuring the filtration, or drainage, characteristics of a fibrous slurry. The results obtained by this test are accurately reproduced in production size systems, e.g. a wet process for the manufacture of asbestos-cement products such as sheet or pipe. The test utilizes a portable, light-weight leaf filter and can be run in 2-3 minutes.

Abstract: A wet process for producing continuous strands from discontinuous inorganic fibers by extruding and aligning a dispersion of said fibers in a liquid medium, which medium contains a gelable agent, into a coagulating bath to gel and convert the agent to a binder for the fibers until they are mechanically interlocked, and subsequently removing the binder. A fibrous strand produced in accordance with the process, with and without the binder included.

Abstract: A portion of a clip fits into the cavity of a hollow core panel and another portion is attached to a structural wall. The portion inside the cavity has normally tapered opposed walls which are straightened, upon insertion into the cavity, to form parallel walls engaging the interior panel surfaces forming the cavity, thus providing a secure fit.

Abstract: Undesirable protein and polyphenol molecules are removed from aqueous liquids or suspensions, such as wort, wine, or beer, by contacting the liquid with acid-treated synthetic magnesium silicates containing less than about 14% magnesium oxide. The resultant liquid is more resistant to chill haze formation. Even better results are obtained if a polyamide is blended with the acid-treated synthetic silicate prior to contact with the liquid. A filter aid, such as diatomite, can also be combined with the acid-treated synthetic magnesium silicate and/or the blends containing the polyamide.
