    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: An object extends into a passage and defines a clearance space with the inner wall of the passage. A hardenable, foamable synthetic resin in flowable state is admitted into the clearance space. Upon hardening and foaming of the synthetic resin, the object is sealingly secured in the passage by the synthetic resin. In a preferred application, the passage is one provided in a coal mine and the object is a hose line for the purpose of suppressing dust. The synthetic resin is advantageously polyurethane including a polyhydroxyl component which contains a polyetherglycol having a hydroxyl number of 300 to 350 and a polyetherglycol having a hydroxyl number of 450 to 500. The polyetherglycol components respectively constitute 80 to 90 parts and 10 to 20 parts of the polyhydroxyl component. The polyhydroxyl component preferably includes a filler in an amount such that the weight of the latter at least equals that of the polyhydroxyl component.

    摘要: Process for isolating aqueous brine layers in underground gas-storage caverns which comprises injecting into the said cavern a liquid polyurethane-resin-forming composition that is hardenable by reaction with water which, upon hardening, forms a resinous barrier between the brine and the gas-storage space thereabove that is essentially impervious to water vapor. The liquid hardenable polyurethane-resin-forming composition comprises a polyol and a polyisocyanate of an aromatic hydrocarbon.

    摘要: A point rail is shiftable transversely on an upper face of a rail base plate between an engaged position bearing on a longitudinally extending and fixed stock rail and a disengaged position spaced transversely of the stock rail. A roller assembly has a mounting plate securable to the rail base plate, a roller support pivotal about a support axis on the rail base plate, a roller carried on the roller support, and a spring biasing the roller upward with a predetermined spring force into a lift position with the roller projecting upward past the upper face for supporting the point rail on the roller. Thus this assembly supports the point rail and, in the engaged position, presses it against the support cleats and the stock rail and it is an integral part of one of the rail base plates.

    摘要: A wire cloth includes warp wires and weft wires which cross each other and are interwoven by a weave pattern. The warp wires are formed in at least two different configurations to define warp wires of first and second types. A length of the first type of warp wires deviates from a length of the second type of warp wires in relation to a particular length unit, with pores being formed in interstices between sections of two neighboring warp wires and crossing sections of two neighboring weft wires.
