Abstract: A device may determine that a failure occurred in an emergency call between a public-safety answering point (PSAP) and a first user device associated with an emergency caller, and may identify, based on determining the failure, one of a first option, a second option, or a third option for redirecting an emergency callback to a contact of the emergency caller. The device may cause, when the first option is identified, the emergency callback to be redirected to a second user device associated with the contact of the emergency caller, and may cause, when the first option is identified, a bearer path to be established between the PSAP and the second user device for the emergency callback.

Abstract: The present disclosure provides for a novel pig design and method of retrieval based on thermal ablation. The pig comprises an external layer and an inner core, where the inner core further comprises at least one incendiary charge comprising at least one exothermic material. When ignited via an ignition source, the incendiary charge releases the exothermic material into one or more thermal dispersion channels. The exothermic material melts the interior of these thermal dispersion channels thereby distributing the exothermic material throughout the pig device causing its destruction via thermal ablation. The destroyed pig can then be easily retrieved from its location in a pipe, as detected via radio signals, without the need for costly excavation of large sections of the pipe.

Abstract: An air-filtration system and method for removably attaching a filter element to portable air-circulation devices and building HVAC air-intakes. One such system provides a filter portion having a circular outer periphery, an inner periphery, a slit running from the outer periphery to the inner periphery that creates a first and second end of the filter portion, and a plurality of fastening mechanisms. One method includes manufacturing a plurality of air-permeable filter sheets, determining a shape of a portable electric fan that includes a fan cage, a support stand, and a motor casing, measuring a size of an inlet side of the fan cage and a size of the motor casing, cutting the plurality of filter sheets such that a plurality of filter portions are created, and attaching a plurality of fastening mechanisms to each one of the plurality of filter portions.

Abstract: A business role for a user is selected based on a job title of the user. IT roles are identified based on the selected business role. Provisioned IT roles of the user are compared to the identified IT roles. Differences between the identified and provisioned IT roles are remedied. The differences may be remedied by changing the business role definition.

Abstract: A solid polymeric body comprising a polymer matrix containing a substantially water-insoluble reagent leachable into a substantially hydrocarbon liquid environment, the matrix being reagent permeative and the body preferably having a softening point substantially above that of the temperature of the liquid fluid environment in which it is to be employed. The body is useful for the introduction of an additive reagent into a substantially liquid hydrocarbon such as crude and refined oils.

Abstract: A thermal energy storage composition is formed of a thermal energy storage hydrate and a solid, water swellable, thermally conducting polymer by blending particles of the polymer with the thermal energy storage hydrate.

Abstract: Process of forming prepasted wallcovering comprising a porous surface that carries a dry coating of polymer particles that become adhesive when wetted by water is made by applying to the surface a dispersion of the particles in a non-aqueous liquid that is stabilized by a polymeric stabilizer and then evaporating the non-aqueous liquid. A dried residue of the dispersion must not form a coherent film and should have a softening point substantially independent of the softening point of the polymeric stabilizer. The polymeric stabilizer is preferably an oil. The non-aqueous liquid is preferably relatively non-volatile.

Abstract: Beads comprising a polymeric matrix containing a releasable lipophilic compound are made by precipitating the compound from solution within the matrix. Beads may be made by forming a homogeneous blend of the compound in lipophilic polymerizable material and subjecting the blend to bead polymerization while the blend is dispersed as beads in an aqueous medium containing hydrophilic polymerization stabilizer. The lipophilic compound may be a behenyl ester wax inhibitor or other reagent useful downhole or for other purposes and preferably has a relatively high melting point. The polymerizable material preferably dissolves the lipophilic compound and may include acrylic acid, methacrylic acid or other hydrophilic polymerizable material.

Abstract: Thermal energy storage compositions comprise a thermal energy storage material, for instance an inorganic hydrate that can undergo a change of hydration with accompanying release or storage of latent heat of hydration at a temperature of 10.degree. to 100.degree. C., held in a matrix of polymeric material, generally acrylic polymer. In one aspect of the invention the composition is in particulate form and so can, for instance, be poured into the heat exchanger in which it is to be used. In another aspect of the invention the storage material includes polyvalent metal ions and the polymeric material is a cationic polymer. In another aspect of the invention the composition is made by forming a solution, generally in water, of all the polymerizable material and most or all of the storage material and then polymerizing the polymerizable material in this solution. The solution is generally a low viscosity fluid and polymerization may be conducted in the heat exchanger vessel in which the composition is to be used.

Abstract: Laundry additive products having improved machine compatibility containing specific amino-silanes. A preferred execution of the technology is a combination of a flexible substrate and the amino-silane. The claimed additives provide enhanced machine protection especially in relation to enamel coated surfaces.

Abstract: Compositions of matter useful in the manufacture of superior cleaning and fabric treating compositions, bleaches, and the like, comprise amino-silane compounds in combination with ingredients such as cationic fabric softeners, or detersive surfactants, or bleach or the like.Such compositions are especially useful in aqueous fabric laundering baths and in combined fabric drying/softening operations since the amino-silane provides a protective effect to the surface of the washing machine or dryer. The compositions are also useful in the formulation of porcelain-safe toilet cleaners, machine- and hand-dishwashing compositions that protect fine chinaware, and for similar uses wherein silicate or metal surfaces come in contact with harsh chemicals, especially in the presence of hot water.
