Abstract: Lubricant compositions adapted for use under extreme conditions comprising a major proportion of an oil or grease base material, and a minor proportion of an aromatic polyamide fibrous substance in an amount sufficient to impart a fibrous texture to the base material.

Abstract: This invention relates to the production casting of molten metal. In such casting, the molten metal being poured into one cavity may be splashed or overflowed into another adjacent cavity. The invention provides a splash guard which defines a barrier to the molten metal and prevents such inadvertent introduction of the molten metal into an adjacent cavity. The splash guard preferably comprises a substantially solid object made of a material, such as graphite, that retains its structural integrity at high temperatures and upon contact with molten metal, but which does not strongly adhere or bond to the molten metal upon cooling. The invention can be embodied in both manual and automatic casting lines. In a manual casting line, the splash guard may physically contact a surface of the mold to create the molten metal barrier between the cavities.

Abstract: Cast iron selected from the group consisting of white iron, compacted graphite iron, malleable iron, gray iron, and ductile iron is cast in a mold in which steel or metal, such as a tube defines a portion of the mold form.

Abstract: A fingernail device which includes a receptacle having a small diameter fluid passageway positioned at an angle to the base of the receptacle. The passageway has a nozzle which directs fluid at a downward angle to the upper surface of the base of the receptacle to create a high-velocity, shallow, fan-shaped fluid stream which flows along and substantially parallel to said base in the direction of the finger tips which are in contact with the base in proximity to the nozzle. The receptacle has a depth such that the level of the fluid retained in it during a cleaning operation will develop a head sufficient to eliminate any splashing, spray-out or extreme turbulance of the fluid in the receptacle. Passageway means are provided for entraining a cleansing agent in the fluid stream.

Abstract: A porcelain veneered dental restoration in which UV fluorescing agent is present in each of the opaque, body and incisal layers at a level to provide the restoration with a uniform fluorescence matching that of natural teeth.

Abstract: Coating compositions for metals effective to inhibit corrosion of ferrous and nonferrous metals susceptible to corrosion, said compositions comprising an inorganic-organic complex in the form of a thixotropic overbased alkaline earth metal sulfonate, particularly calcium, organic sulfonate, complexed with an alkaline earth metal, particularly calcium, carbonate; and linseed oil or a drying oil having drying properties generally similar to linseed oil, said linseed oil constituting at least 15% and, particularly, higher percentages up to about 50%, by weight of the coating compositions; and a drier, preferably of the paint drier type; and particularly advantageously also containing an epoxidized oil, particularly an epoxidized drying oil; and, also, such ingredients as mineral oils, waxes, petrolatums and resins.
