Abstract: A pipeline repairing kit comprising (a) a sealed, flexible envelope; (b) two removable means dividing said envelope into at least first, second and third compartments, said means being removable selectively to connect the first and second and third compartments without opening the sealed envelope; (c) measured quantities of the parts of a two-part curable resin system in the first and second compartments; and (d) an elongated flexible bandage member made of absorbent material disposed in said third compartment, said member including an integral closeable vent, whereby an elongated resin-soaked flexible bandage member adapted for wrapping around a pipeline can be provided by first removing the removable means between said first and second compartments to thereby mix the parts of the resin system, next removing the other removable means and bringing the mixed resin into intimate contact with said elongated flexible member, and then manually manipulating the envelope so as to thoroughly impregnate said bandage m

Abstract: A package comprising an integral tray and separable tool or paddle for delivering material components from one depression of the tray to another and for subsequently mixing them prior to their use. It is designed for storing component materials in a multiple component system, such as a thermosetting resin system. Material is accurately transferred from one depression to the other by the associated tool. The interior surfaces of the depressions are complementary to the configuration of the intersecting edges of the tool or paddle.

The first component comprises a paste which includes magnesium oxide, a dispersing agent, such as a ligno sulfonate and water. The second component is comprised of a dihydrogen phosphate salt, such as mono hydrogen ammonium phosphate or sodium dihydrogen phosphate, and the combination of a trisodium phosphate and a second agent selected from the group consisting of a polyphosphate salt and an alkyl acid phosphate or both. The second component will also include a minor amount of water to make the paste.

Abstract: Disclosed is a cryogenic gel, and a process for making such a gel from a liquid cryogen having at least a methane component, which normally comprises a majority of the cryogenic liquid, by flash vaporizing the cryogen so that a relatively small portion of the weight of the cryogen becomes vaporized while a remainder forms a mist of small cryogen droplets suspended in the vapor. After flash vaporization, a gelling agent is injected into the cryogen vapor-mist mixture. The gelling agent is present so that it forms between about 0.1% to about 25% (by weight) of the resulting gel and is selected so that it is a solid at the temperature of the liquid cryogen and a liquid or a gas at ambient temperature. Water and methyl alcohol are preferred gelling agents. After the injection of the gelling agent the mixture is segregated into a gaseous phase and a condensed phase or gel comprising the liquid cryogen droplets and the injected gelling agent.

Abstract: A conduit end is sealed around one or more than one insulated conductor by using a chamber (4) having a peripheral wall, a base with an opening through it communicating with the conduit (2) and an opening opposite the base. The conductor(s) (3) extend through both openings; a pre-formed annular body of a setting resin composition (8) is inserted while in a pasty or viscous condition into the chamber to encircle the conductor or conductors. Axial pressure is then applied to the still pasty or viscous annular body to cause it to flow and form a sealing body in peripherally continuous contact with the chamber and with the, or each, insulated conductor, after which the resin composition sets. A kit for use in the method is also claimed.

Abstract: A system for gelling cryogenic liquid in which a jet pump is used to educt cryogenic vapor from a gel storage container, mix that educted vapor with steam or other gelant vapor, and inject the resultant mixture into a fine spray of cryogenic droplets, is described herein.

Abstract: A kit containing the components essential for repairing, in situ, damaged or fractured porcelain dental prostheses. Such repair includes cleaning, shaping, and priming the damaged area, applying a bonding agent preferably containing two silanes and a water-displacing solvent, then applying a filling agent comprising vitreous powder and a resin binder, allowing the agent to set and harden, and finishing.

Abstract: A parallel tube resin bolting package is disclosed for use in resin bolting operations. The composite package has a generally figure 8 shape in cross-section, with one compartment containing a polyester resin while the other compartment contains a hardener composition. The resin bolting package is particularly useful in applications where the pre-drilled hole has a relatively small diameter.

Abstract: This invention relates to an apparatus for separating platelets from blood samples by subjecting the blood sample to centrifugal force in the chamber while displacing the platelets from the blood sample by injecting a relatively small volume of saline into the centrifugally outer end of the chamber. In the preferred apparatus, the saline is injected into the blood sample by driving the chamber supporting the blood sample against a saline filled collapsible cavity under the influence of centrifugal force.

Abstract: A bone cement in pliable and moldable form which when applied to bone and cured has superior characteristics containing an admixture of methylmethacrylate copolymers, methylmethacrylate, and between 15 and 75% by weight of an inorganic composition of between about 90 and 99% of a bio-active glass ceramic powder having a particle size of 10-200 micrometer and between 1 and 10% of vitreous mineral fibers having a length of less than 20 mm. The composition also contains a curing catalyst and, preferably, an accelerator.

Abstract: A multi-compartment capsule having a longitudinally extending tubular inner compartment for containing a catalyst and a longitudinally extending tubular outer compartment around the inner compartment for containing a resin composition. The longitudinally extending tubular inner and outer compartments are formed by a single-ply film strip of polyester material to which are welded along opposite longitudinal edges two-ply strips having a first ply of polyester material welded to the polyester film strip of the single-ply strip and a second ply of polyethylene material. The composite sheet made up of the single-ply strip and two-ply strips is folded upon itself along one two-ply marginal edge to form the tubular inner compartment so that the polyethylene ply material at the composite strip edge contacts such ply material when folded and is welded thereto.

Abstract: A cable repair kit including the component parts thereof and a process for repairing in the field simply and quickly high-voltage electrically conductive cables whose outer jackets have been damaged but whose inner conductors have not been damaged. The kit comprises a portable container sealingly enclosing abrasive material for abrading the damaged cable portion; a cleaning compound; a filler compound for restoring or filling in the damaged region of the cable jacket; a bonding agent for bonding a patch of insulative, flexible material circumferentially about the section of the cable wherein the damaged portion is located; the insulative patch material; and a flame-resistant tape for aiding the bonding agent in joining the patch to the cable, as well as providing the patch with a smooth and continuous surface at a junction between side edges thereof and the cable surface.

Abstract: The disclosed method for applying an epoxy mortar is highly streamlined and involves little more than blending the curable epoxide binder for the mortar, adding aggregate and water to form the mortar, spreading the mortar on a surface, and curing the mortar in place on this surface. Flood coats, special trowelling techniques, and hydrophobic coatings for the aggregate particles are usually unnecessary. The simplification of the mortar-applying method depends upon formulating an epoxy binder material which includes a polyfunctional primary amine having an extremely low affinity for water, particularly a polynuclear cycloaliphatic polyamine such as methylene-bis-(4-cyclohexyl amine).

In use, the marks are read by a reading device and, depending upon a selection which is made, a particular cell is perforated to allow the contents thereof to be distributed.

Abstract: To accelerate the curing of epoxide resins by aromatic, heterocyclic, or cycloaliphatic polyamines there are employed salts of trifluoromethanesulfonic acid.
