Abstract: A system for monitoring multiple patients within a facility comprises a plurality of monitoring apparatuses, a central communication hub, and a plurality of notification devices. The monitoring apparatuses generate data relating to the status of patients, and send the data to the communication hub. The data may include an alarm signal. In a variant, the monitoring apparatuses do not generate alarm signals. Rather the communication hub processes the data and generates alarms if needed. Alarms are sent by the communication hub to the notification devices to inform employees of the facility of the source of the alarm.

Abstract: Methods of preparing conductive thermoset precursors containing carbon nanotubes is provided. Also provided is a method of preparing conductive thermosets containing carbon nanotubes. The carbon nanotubes may in individual form or in the form of aggregates having a macromorpology resembling the shape of a cotton candy, bird nest, combed yarn or open net. Preferred multiwalled carbon nanotubes have diameters no greater than 1 micron and preferred single walled carbon nanotubes have diameters less than 5 nm. Carbon nanotubes may be adequately dispersed in a thermoset precursor by using a extrusion process generally reserved for thermoplastics. The thermoset precursor may be a precursor for epoxy, phenolic, polyimide, urethane, polyester, vinyl ester or silicone. A preferred thermoset precursor is a bisphenol A derivative.

Abstract: An oxidizable hydrocarbon is oxidized in a reaction zone at elevated temperature in the presence of a liquid reaction medium by introducing the hydrocarbon and a feed stream containing molecular oxygen to the reaction zone under conditions sufficient to oxidize at least a portion of the hydrocarbon; withdrawing at least a portion of the liquid reaction medium from the reaction zone; passing at least a portion of the withdrawn liquid reaction medium to an oxygen injection zone located external to the reaction zone; contacting the liquid in said oxygen-injection zone with a gas stream containing molecular oxygen under conditions sufficient to form a two-phase gas/liquid mixture; and passing said two-phase gas/liquid mixture to the reaction zone as the feed of molecular oxygen thereto.

Abstract: Acetone produced as a by-product in the reaction of methyl acetate with carbon monoxide and hydrogen in the presence of a Group VIII noble metal catalyst and methyl iodide is recovered from the reaction mixture by supplying acetone to provide an acetone to methyl iodide molar ratio of at least 1:10 and distilling the mixture comprising methyl iodide, acetone and methyl acetate to separate substantially all of the methyl iodide and the supplied acetone and some of the methyl acetate from the remaining acetone and methyl acetate and thereafter separating the acetone from the methyl acetate.

Abstract: Water is removed from the methacrolein-containing effluent produced by the catalytic oxidation of isobutylene or tertiary butyl alcohol by quenching the effluent in water in a plurality of quenching steps under graduated increasing pressure.

Abstract: In an oxidation process for converting methacrolein to methacrylic acid, methacrylic acid is recovered by cooling and condensing the effluent from the oxidation, followed by azeotropic distillation of the condensate with a suitable solvent, such as methyl n-propyl ketone. The condensed effluent contains methacrylic acid and water as the major components along with by-product acetic acid, a minor amount of unreacted methacrolein and impurities. Substantially dry crude methacrylic acid is separated as a bottom product from the azeotropic distillation and an azeotrope of water and the solvent is taken overhead and condensed. After condensation, solvent-rich and water-rich phases form and are separated. The solvent-rich phase is returned to the distillation column as a reflux, while the water-rich phase is sent to a stripping column for recovery of residual solvent. Water is withdrawn from the bottom of the stripping column and recycled or discarded, as desired.

Abstract: Methacrolein is recovered from a gaseous mixture containing it by bringing the gaseous mixture into contact with acetic acid.
