Abstract: In an inorganic cement grouting system for use in anchoring a reinforcing member such as a rock bolt in a hole, e.g., in a mine roof, by the reaction of the mixed components of the system so as to form a hardened grout around the reinforcing member, the two separate components of the system are: (1) a slush or sludgy mass of a particulate inorganic cement, e.g., an hydraulic cement, and a liquid which is nonreactive therewith, preferably a hydrocarbon, and (2) a liquid, e.g., water, which is reactive with the cement; and sand is present in the cement slush and/or the reactive liquid. The sand is graded to the extent that the deviation from the median particle size is more than about .+-. 20, and usually more than about .+-. 30, percent; and particles larger than about 600 microns constitute no more than about 10 percent, and preferably about 5 percent or less, of the total volume of the sand.

Abstract: Spheroidal agglomerates of malachite crystals are prepared by bringing together solutions of a cupric salt, a bismuth salt and an alkali metal carbonate or bicarbonate to form a mixture containing amorphous hydrated copper carbonate, and then holding the mixture, without agitation, at a temperature of less than about 55.degree. C.

Abstract: Perovskite catalysts of the general formula ABO.sub.3 having increased stability through the incorporation of metals having low first ionization potentials, and their use in oxidation and reduction reactions.
Abstract: In a method of anchoring a reinforcing member such as a rock bolt in a hole, e.g., in a mine roof,wherein two separate components of an inorganic cement grouting system are mixed, preferably in the hole, e.g., by the rotation of the reinforcing member, whereby the components react to form a hardened grout around the reinforcing member, the two components of the system delivered into the hole are: (1) a slush or sludgy mass of a particulate inorganic cement, e.g., an hydraulic cement, and a liquid which is nonreactive therewith, preferably a hydrocarbon, and (2) a liquid, e.g., water, which is reactive with the cement; and a particulate aggregate such as sand preferably is present in the cement slush and/or the reactive liquid. The inorganic cement constitutes more than 10 percent, and the weight of any aggregate present is no more than about 80 percent, of the total weight of the two components. The two components preferably are delivered into the hole separately, e.g.
Abstract: A composite, photohardenable element comprising in intimate surface contact (a) a resist layer, photohardenable by exposure to actinic radiation and; (b) a soluble layer comprising a macromolecular organic polymer and at least one ultraviolet absorbent dye or pigment. In the preferred elements, the layers are disposed between and adherent to a cover sheet and a support film, respectively.
Abstract: In an inorganic cement grouting system for use in anchoring a reinforcing member such as a rock bolt in a hole, e.g., in a mine roof, by the reaction of the mixed components of the system so as to form a hardened grout around the reinforcing member, which system has the following separate components: (1) a slush or sludgy mass of a particulate inorganic cement that sets by hydration and a liquid which is nonreactive therewith, preferably a hydrocarbon, and (2) water containing a particulate aggregate such as sand, a small amount of polyethylene oxide and/or polyacrylamide in the aggregate-containing water component not only thickens the water to prevent its loss from the hole, but acts as a lubricant to facilitate insertion of the reinforcing member while permitting the resulting grout to develop an acceptable shear strength.
Abstract: In an inorganic cement grouting system for use in anchoring a reinforcing member such as a rock bolt in a hole, e.g., in a mine roof, by the reaction of the mixed components of the system so as to form a hardened grout around the reinforcing member, which system has the following separate components: (1) a slush or sludgy mass of a particulate inorganic cement that sets by hydration and a liquid which is nonreactive therewith, preferably a hydrocarbon, and (2) water, higher early strength is achieved when the cement is one which contains (by weight) about from 20 to 40 percent of 3CaO.3Al.sub.2 O.sub.3.CaSO.sub.4 and about from 10 to 35 percent of chemically unbound CaSO.sub.4, the remainder being substantially .beta.-2CaO.SiO.sub.2. The strength advantage obtained with this cement when used in nonaqueous slush form makes it particularly adapted for use in a system for anchoring rock bolts in a mine roof.

Composites in which the acrylonitrile polymer is in the form of a fabric are particularly useful for the preparation of laminates.

The resulting product is well dispersible in blends of aromatic and aliphatic hydrocarbons. Dispersions containing the above reaction product and an elastomer find application as adhesives or surface-coating compositions.
Abstract: Apparatus mountable on a pipeline of pipes welded end-to-end and having a self-propelled carriage mountable on the pipeline for travelling thereon. The carriage carries annular casings made to open up and receive the pipeline when mounting the carriage thereon and operble to a closed position circumferentially of the pipeline. A rotor travels in each casing circumferentially of the pipeline as the carriage moves axially of the pipeline. Each rotor has a tool holder that has a cleaning tool with a cutting edge tangential to the pipeline for cleaning. A cam surface on the tool holder moves in advance of the cutting edge and cams the tool holder upwardly when a weld is encountered between the pipe sections so that the cleaning tool is well protected.

Abstract: A polyurethane adhesive, suitable for bonding of shoe uppers to shoe soles, is based on an isocyanateterminated prepolymer made from tolylene diisocyanate, a poly(tetramethyleneoxy) glycol, and a poly(ethyleneoxy) compound having 7-30 ethyleneoxy groups and 1 or 2 hydroxyl groups. This prepolymer can be cured with a mixture of a methylenedianiline/sodium chloride complex with urea at a temperature of 70.degree. C, which is safe for the usual shoe materials. Adhesive compositions containing both the prepolymer and the curing agent have at room temperature a potlife of at least 24 hours.
