    摘要: A method of and an adhesive cartridge for securing an anchor or the like in a bore hole or the like. The cartridge comprises an outer tube and an inner tube within this outer tube. Between the inner and outer tube is a mass of synthetic-resin material and filler. The inner tube is filled with a hardener capable of reacting with the synthetic-resin to form a mass capable of holding the rock anchor or the like in the borehole. At least the outer tube is made of an elastomeric polymer with which is mixed a filler that renders the outer tube completely opaque. The inner tube may also be extruded simultaneously with the outer tube of the same synthetic-resin material. It is also possible otherwise to partition the interiors of the outer tube, or to provide the one component in the outer tube directly in contact with the other component but unmixed therewith.

    摘要: Self-curing or curable materials are obtained from the distillation residues of coal hydrogenation by condensing a residue of this type having a softening point of 30.degree. to 54.degree. C. in a first stage with a mono- or dihydroxybenzene and/or a methylhydroxybenzene and/or an ethylene substituted benzene. These reactants are used at a ratio of residue to benzene derivative between 1:1 and 2:1 and the reaction is carried out in the presence of acid at a pH of 1 to 2 and at a temperature of 90.degree. to 100.degree. C. In a second stage the thus obtained reaction product is then further reacted at about the same temperature with an aldehyde. As a result a novolak-type resin is obtained. The invention permits the making of inexpensive self-curing or curable materials with properties similar to those of phenolic acids. Besides, the invention also provides an outlet for the high boiling residue of the extractive coal hydrogenation which otherwise had little use.

    摘要: Synthetic form masses are described which are derived from thermoplastic polyolefins as well as mixed and copolymerisates thereof and a coal liquification product. The coat liquification product is a residue which precipitates out during extractive hydrogenation and has a softening point between 70.degree. and 200.degree. C. The thermoplastic polyolefin contains a component of polar, aromatic or cyclic monomers, which improve the compatibility of the components in the mixture. The form masses from this mixture, which may include filler material, have excellent tear resistance properties.

    摘要: Coal-tar pitch is heated to a temperature which is at least 100.degree. C above its softening point but below its decomposition temperature and is mixed with a filter aid, such as kieselghur or activated carbon prior to filtering the pitch at at least the preheat temperature so as to remove ashes, soot and heavy metals therefrom. The thus-purified pitch is then coked. In this manner, it is possible to obtain high-quality, anisotropic acicular coke which is readily convertible into graphite.

    摘要: A composition for sound absorbent panels, which may be utilized in construction elements, comprises a mixture of 70 to 97 weight percent of carbon-contained material and a binder of synthetic plastic material. The carbon-contained material used in the composition contains 50-60% of pure carbon and 40-50% of inorganic constituents and may be obtained from residues of coal hydrogenation or pitch filtration. The material is treated at an elevated temperature and under pressure before the binder is added thereto and then the obtained compound is formed into a panel.
