Abstract: A system and method for communicating presence information that can include at a first server of a communication platform, receiving an authorization token of a first client application; verifying at least one permission associated with the authorization token; registering a presence status of the first client application upon verifying the at least one permission of the authorization token; at a second server of the communication platform, accepting an incoming communication request; retrieving communication instructions according to the incoming communication request; identifying an instruction to communicate with a communication destination of the first client application; accessing the presence status resource of the first client application; establishing communication with the first client application according to the accessed presence status resource.

Abstract: The invention relates to an apparatus for use with a shale shaker and more specifically to a drilling fluid recovery chute that is attached to and receives tailings from the discharge end of a shale shaker. The drilling fluid recovery chute removes drilling fluids from the waste tailings that are discharged from the shale shaker so that they can be reused or recycled. The invention also relates to a method for recovering drilling fluids from the tailings of a shale shaker.

Abstract: Novel hindered alkoxy siloxane compounds and compositions containing hindered alkoxy siloxane compounds are provided. The compositions include a polymer/crosslinking system which is composed of a self crosslinking resin comprised of a silicone fluid modified with pendant or terminal silanes containing hindered alkoxy groups, or a silanol fluid and a crosslinking compound, of a mixture thereof. These components are first emulsified and then formulated into a latex sealant by blending with a separate emulsion of an appropriate catalyst. Crosslinking occurs upon drying of the emulsion.
