Abstract: Rubber compositions comprising an acrylate or methacrylate salt, an elastomer curable with a peroxide initiator and a plasticizer having one or more epoxide groups per molecule display lower compound Mooney viscosity, higher MH/modulus, increased hardness and improved odour.

Abstract: Plasma treatment for producing carbonaceous field emission electron emitters is disclosed. A plasma of ions is generated in a closed chamber and used to surround the exposed surface of a carbonaceous material. A voltage is applied to an electrode that is in contact with the carbonaceous material. This voltage has a negative potential relative to a second electrode in the chamber and serves to accelerate the ions toward the carbonaceous material and provide an ion energy sufficient to etch the exposed surface of the carbonaceous material but not sufficient to result in the implantation of the ions within the carbonaceous material. Preferably, the ions used are those of an inert gas or an inert gas with a small amount of added nitrogen.

Abstract: The invention provides a process for preparing a filled halobutyl elastomer which comprises admixing a halobutyl elastomer, particles of filler and a silane that has at least one hydroxyl group or hydrolysable group attached to a silicon atom of the silane, and curing the filled halobutyl elastomer with sulphur. The invention also provides a filled composition that has improved properties when compared with known carbon black filled elastomeric compositions.

Abstract: A polymer composition useful to produce a vulcanizate having improved compound scorch safety is described. The polymer composition includes three components. The first component is a polymer selected from the group comprising nitrile polymers and ethylene polymers. The second component is a salt of a strong base and a weak acid, the salt comprising a metal selected from Group I of the Periodic Table of Elements. The third component is a vulcanization system comprising an inorganic peroxide compound and a sulfur containing compound. The polymer compositions may further comprise optional ingredients such as one or more of: a polycarbodiimide and a filler. Vulcanizates produced from the polymer composition have a surprising and unexpected combination of properties.

Abstract: Core/shell particles comprising a core comprising an elastomer having a TG value of <0° C., onto which a shell of a crosslinked copolymer is grafted, where the proportion of the crosslinking component in the copolymer of the shell is from 5 to 90% by weight, based on the total amount of the comonomers of the shell copolymer, are suitable as toughening agents for epoxy resins, with which they have good compatibility.

Abstract: A method for the reactive coating or reactive encapsulation of fluidizable, organic or inorganic, anisotropic or isotropic substrates with a cross-linking, thermostable and insoluble thermoset by spraying onto substrates a cationically curing one-pot liquid resin system comprising a cationic initiator, which method comprises fluidizing the substrates in a fluidized-bed coater at a temperature above the activation temperature of the cationic initiator and then injecting the one-pot liquid resin system into the fluidized-bed coater through a spraying device, the one-pot liquid resin system having a gelling time of from 1 to 60 seconds at from 100 to 150.degree. C., results in unagglomerated substrates having a cross-linked, thermostable and homogeneous coating.

Abstract: Core/shell particles comprising a core comprising an elastomer having a T.sub.G value of <0.degree. C., onto which a shell of a crosslinked copolymer is grafted, where the proportion of the crosslinking component in the copolymer of the shell is from greater than 5 to 90% by weight, based on the total amount of the comonomers of the shell copolymer, are suitable as toughening agents for epoxy resins, with which they have good compatibility.

Abstract: There is provided a fluidized bed reactor for working up carbon coated particles, particularly nuclear fuel particles or fertile material particles consisting essentially of a cylindrical portion connected to a conical portion, there being provided gas supply pipes, gas distribution space and gas distribution heads within the conical reactor lower portion, the gas distribution members being arranged in at least two superimposed planes and distributed symmetrically over the cross-section of the reactor.

Abstract: Esters of alkyl-substituted hydroxyaromatic carboxylic acids (especially alkyl-substituted salicylic acids) and the like, in which the alkyl substituent contains at least about 10 carbon atoms, are useful as dispersant additives for lubricants and fuels. Particularly useful are esters in which the substituent is derived from propylene, 1-butene or isobutene and has a molecular weight of about 150-1750, and in which the alkyl moiety is derived from pentaerythritol. Such esters are preferably prepared by the reaction of the corresponding organic hydroxy compound with a vic-hydroxyalkyl ester of the salicylic acid.

Abstract: A strand adapter for mechanically and electrically coupling aerial closures and cable terminals to a messenger cable is disclosed. The adapter is configured such that a range of messenger cable sizes can be advantageously accommodated. In addition, the adapter includes provisions for diminishing rotation during installation thereby simplifying the procedures for coupling aerial closures and cable terminals to a messenger cable.

Abstract: This specification describes a process and apparatus for closing leaks and spraying a sealant composition to interior walls of an underground gasoline tank such as is used in retail gasoline service stations. A gas tank suspected of leaks is emptied of stored gas and purged with compressor air applied thru a valve control and pipe conduit threadly inserted in the conventional fill pipe of the tank. The pipe conduit includes a means defining an aperture at the lower extremity of the conduit which extends into the tank interior. An explosion safety level meter is attached to the pipe conduit for providing a humanly detectable signal of the environment within the tank. An excavation enables a craftsperson to cut an access port through the tank wall for entering the tank interior, cleaning-up residue, sandblasting the interior walls, and spraying a sealant composition of thixotropic polyester resin and a catalyst onto the sandblasted walls.

Abstract: A non-flammable rug cleaning composition utilizing flammable hydrocarbons as a propellant is obtained by the incorporation of at least 0.3 by weight of lauryl alcohol into the composition which includes from 0.5 to 5% by weight of CH.sub.3 (CH.sub.2).sub.10 CH.sub.2 OSO.sub.3 M where M is a positively charged cation.

Abstract: Apparatus for enclosing splices between two or more multiconductor cables is disclosed. The apparatus includes a unitary support member which has affixed thereto cable ground sheath bonding circuitry, cable support apparatus, and clamps for securing the apparatus to a messenger strand. Completed splice connections are sealed in a unitary, flexible, weatherproof cover.
