Abstract: A highly weather-resistant, thermoformable sheeting prepared by mixing from 45 to 70 parts by weight of a rigid thermoplastic resin selected from the group consisting of polyvinyl chlorides and copolymers each of which is composed mostly of a vinyl chloride and a small amount of a monoolefinic monomer copolymerizable with the vinyl chloride, from 20 to 50 parts by weight of a thermoplastic resin obtained by a graft polymerization of from 20 to 40 parts by weight of an ethylene-propylene copolymer rubber or ethylene-propylene-diene terpolymer with from 60 to 80 parts by weight of a vinyl monomer mixture consisting of from 40 to 90 percent by weight of an alkenyl aromatic compound and from 10 to 60 percent by weight of at least one monomer copolymerizable with the alkenyl aromatic compound, and from 5 to 35 parts by weight of an acrylonitrile-butadiene rubber, with from 5 to 50 parts by weight of a plasticizer or plasticizers added to the 100 parts by weight of the resinous mixture.

Abstract: Single crystalline ferrite particles are obtained by the thermal reaction of ferric oxyhydroxide, ferric hydroxide, porous ferric oxide made therefrom or ferric oxide having a particle size less than 0.8.mu. with a strontium or barium compound such as the oxide hydroxide, the carbonate or the carboxylate in the presence of a small amount of a metal chloride flux such as strontium chloride or barium chloride.The resulting particles have a well-defined, hexagonal plate configuration and are particularly adapted for the production of anisotropic magnets.

Abstract: Anhydrous deep-drawing agents having improved wetting and deep-drawing properties are described which can be applied to the surface of a metal to be drawn well in advance of the drawing process. The agent consists essentially of a deep-drawing mineral oil carrier in which is dissolved dimeric carboxylic acids prepared by oligomerization of unsaturated fatty acids having 16 - 26 carbon atoms.

Abstract: 9-Hydroxydibenzo[a,g]quinolizinium compound of the formula: ##STR1## wherein R.sub.5, R.sub.6, R.sub.8 and R.sub.13 are each hydrogen or lower alkyl, and X.sup.- is a pharmaceutically acceptable anion. Additional substituent may be present on ring A and D. Betaines and 9-acylates are also provided. They inhibit growth of transplanted sarcoma or leukemia strains into mice.

Abstract: A symmetric screw thread system including external threads each profiled to have a flank angle of (70 .+-. 2).degree. and a flat root located at (0.27 .+-. 0.02)H from an intersecting point of two lines extended from opposing flanks of two adjacent threads and connected to said opposing flanks through arcs of a radius (0.15 .+-. 0.02)p where H is the depth and p is the pitch of the threads. Alternatively, the system may include external threads configured to have a flank angle of (106 .+-. 5).degree. and connected by a root having a radius of (0.30 .+-. 0.01)p.

Abstract: An elbow prosthesis comprising a humeral member and an ulnar member, in which each member comprises a joint portion for forming the joint of the prosthesis and an implant portion for implantation into the bone, the joint portion of the humeral member being capable of being received by the joint portion of the ulnar member in snap-fit engagement, while permitting the humeral member to pivot relative to the ulnar member.

Abstract: Novel berbine derivatives of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each methoxy or jointly a methylenedioxy, R.sub.3 is methyl, 4-methoxyphenyl or phenylvinyl, and X is a pharmaceutically acceptable anion. They inhibit the growth of transplanted sarcoma strain in mice.

Abstract: Complex enzymes which can lyse the cell wall of a variety of microorganisms such as bacteria, fungi, yeast, Basidiomycetes and chlorella are produced and recovered from cultivation of Pellicularia sasakii or Pellicularia filamentosa.

Abstract: A novel method of preparing a recipe for the reproduction of a particular color on a coloring material from a number of coloring agents or dyes, which comprises passing white light rays through a number of optical filtering means, controlling filtration characteristics of the filtering means to correspond to spectral distribution characteristics of the dyes, projecting on the coloring material the light rays which have passed through the filtering means to produce a monitoring color thereon, and modulating wavelength and amplitude outputs of the filtering means until the monitoring color simulates the particular color. The method precludes the complicated task of evaluating color affecting factors such as surface texture of the coloring material and eliminates the need for repeated coloring tests.

Abstract: In a method of preparing color separation printing patterns from a multi-color original design, the design is irradiated by light and multi-color light components reflected from minute picture elements constituting the design are detected. The detected light components are converted to picture element data representative of the optical energy level of the reflected light corresponding to each picture element. The picture element data are stored and filtered to form quantized picture element data indicative of several series of reflected light components respectively falling within different preselected ranges of color. This is done by comparing successive picture element data to detect significant differences in energy level indicative of color changes. The reason for each substantial difference in output level is determined, e.g., pattern defect or imperfection, and the filtered picture element data are stored along with change codes indicative of the reason for the difference.
