Abstract: Glass compositions are disclosed that are particularly useful in comminuted form as sources of micronutrient elements for soils. The glasses are based on phosphorous as P.sub.2 O.sub.5 and contain a nutrient amount of a micronutrient metal in oxide form, such as zinc, copper, manganese, molybdenum, or boron oxides or mixtures thereof, plus a solubility control agent. The control agent is a metal compound or mixture of metal compounds, usually potassium or sodium oxide or potassium or sodium chloride, and is present in the glass to provide a controlled release of the micronutrient metal, both as to amount and rate.

Abstract: Friction material adapted for use, for example, as a brake lining is disclosed characterized in that the material contains a particulate normal spinel as a friction modifier. The friction material may be conventionally supported as by a shoe or disc.

Abstract: A process is disclosed for the preparation of hydrocarbyl metal halides, such as alkyl tin chlorides, in which a reaction between the metal in its metallic state and a hydrocarbyl halide is catalyzed by a complex formed between a hydrocarbyl metal halide and a dihydrocarbyl sulfoxide. In the case of tin, for example, the complex may be represented by the formula:R.sub.n SnR'.sub.(4-n).NR.sub. 2 SOin which R represents hydrocarbyl substituents, R' represents the halogens, n is a whole number from 1 to 3, inclusive, and N is a whole number from 1 to 5 inclusive.

Abstract: A class of organic compounds is disclosed comprising substituted anilides of 3-tert. butyl-6-methyl-5-nitro-salicylic acid, characterized in that the anilide portion is substituted only in the 4' position or only in the 2', 4' positions from a relatively small number of monovalent substituents. Such compounds are useful in the control of microorganisms and especially as anthelmintics, that is, therapeutic agents for destroying parasitic life, such as intestinal worms. Certain of the compounds are especially effective against Nematodes such as Haemonchus and Trematodes such as Fasciola.

Abstract: Apparatus for automatic control and deposition of particulate material, such as powdered dry process porcelain enamel or the like, to a heated substrate, utilizing dispensing means adapted to contain particulate material and supported in overlying relation to the article to be coated, with mechanism for oscillating and actuating the dispensing means to provide for controlled application of particulate material to the article. Specifically, an improvement over the apparatus of U.S. Pat. No. 3,802,384 issued Apr. 9, 1974, whereby abutting ends of the dispensing means are biased along a generally vertical plane.

Abstract: A cordierite-type glass-ceramic and a process for its preparation are disclosed, characterized in that a nucleating agent in a small amount is added preferably to a glass batch capable of producing cordierite. The nucleating agent aids in forming a glass-ceramic refractory of relatively large amounts of crystalline cordierite. The melt is quenched and ground to an average particle size no greater than about minus 325 U.S. Standard sieve. This particle size in combination with a relatively small amount of a nucleating agent has been found to increase the amount of cordierite formed during crystallization and simultaneously decrease the amount of glassy phase remaining in the glass-ceramic. In this manner, the ultimate product more nearly resembles pure cordierite. The nucleating agent includes the compounds, usually the oxides, of Mo, Ta, Zr, Nb, Ti, Li, As, and mixtures thereof. The preferred nucleating additive or agent is Nb.sub.2 O.sub.5.

Abstract: There is provided a highway lane divider and roadmarker, adapted to be affixed to a pavement surface.Said marker characterized by a planar base, said base having protruding downwardly therefrom a multiplicity of studs arranged in spaced relationship, and dispersed substantially symmetrically over the area of said base to improve the bonding characteristics of said roadmarker to pavement.
