In a magnetic recording substance comprising a non-magnetic support and a magnetic recording layer provided on the support, carbon black having a surface area of at least 700 m.sup.2 /g and an oil absorption of at least 300 ml (DBP)/100 g is contained in the magnetic layer thereby lowering the surface electric resistance without deteriorating the characteristics of the magnetic recording layer.

A method for adsorbing harmful substance comprising at least two adsorptive units composed of a plurality of cylindrical or bag-shaped adsorptive elements made of a cloth-like or sheet-like adsorptive material having a 0.1 m/second pressure loss of not more than 15 mm Aq/cm, said adsorptive material consisting predominantly of active carbon fibers having an equilibrated adsorption amount of benzene of not less than 300 mg/g and an adsorption rate constant of benzene of not less than 0.2 /minute,...

In a magnetic recording substance comprising a magnetic recording layer on one side of a non-magnetic support and a back layer on the other side thereof, the back layer is provided by coating a powdered solid with a binder and coating solvent and having spike grains with a height of 0.8 to 5 microns and an interval or pitch of at least 200 microns on the surface thereof and a friction coefficient of at least 0.25.

Substance P, an undecapeptide of mammalian origin, and its analogs containing its essential amino acid sequence, are substantially nonaddictive analgesics when administered to mammals such as humans and other warm-blooded animals by intraperitoneal or intramuscular injection in analgesically effective amounts.

In a magnetic substance conveying apparatus, to convey the magnetic substance along the outer periphery of an outer cylinder made of non-magnetic material by the relative rotational movement between the outer cylinder and an inner cylinder inside the outer cylinder and having magnets wound therearound in a spiral fashion, the angle of the spiral of the magnets wound over the inner cylinder gradually increases as the spiral advances toward the end thereof.

A spot removing substance which may be used on carpets, rugs, upholstery and the like is made by thoroughly mixing a colloidal clay adsorbent, a fine clay adsorbent having deodorizing properties, and a heavy sand carrier, in volumetric proportions of about 80%, 10%, and 10%, respectively.

The present invention provides a new device and method for automatically detecting and regulating and/or removing concentrations of various substances in aqueous solutions, such as for example, regulating the degree of pollution of urban rivers or industrial effluents, by electrolyzing the ions of these substances dissolved therein through a flow electrolyte cell; then depositing and condensing or dissolving, automatically and with high accuracy, continuously or discontinuously, according to the...

An antibiotic FR-1923 substance which is active against a pathogenic bacteria and useful as an effective antimicrobial agent in treatment of infections disease caused by bacteria, the antibiotic FR-1923 substance being produced by fermentation of Nocardia uniformis var. tsuyamanensis ATCC 21806 and its mutant in a nutrient medium.

Apparatus for removing a powdered substance, such as dried eggs, from a container and feeding the substance at a uniform rate to another location includes a rotating platform on which the container is placed, a suction pipe located over the container and having its lower end near the top surface of the powdered substance and attached to a pair of blades which support the pipe in the powdered substance, feed the powdered substance to the suction pipe and maintain the surface level of the powdered...

Certain non-ionic surfactants have been found to be useful in reducing serum cholesterol levels in animals and man. The surfactants are incorporated to at least 20 percent in pharmaceutical compositions so that the (C.sub.2 H.sub.4 O) groups amount to 0 to 30 percent of total molecular weight and the (C.sub.3 H.sub.6 O) groups have a partial molecular weight of 2250 to 3250. The surfactants are prepared by sequential addition of ethylene diamine. "Tetronic 701" and "Tetronic 702" are suitable; o...
