Abstract: A system and method for providing backup communications using Power over Ethernet (PoE) are disclosed. A backup communication system (BCS) is provided as part of a networked (TCP/IP) hospital communication system. The BCS is coupled to a power line used to provide power to a PoE switch. When TCP/IP communications are interrupted, the BCS receives patient call signals from patient room terminals over a secondary communication mode of the power line, and transmits those call signals to a nurses' station. The call signals can be generated by coupling a pulse-coded AC signal onto the PoE wires, or by sending voltage coded data in one direction and current-coded data in the other direction. Different signals or signal levels can be used to distinguish normal patient calls, patient emergency calls, and code calls. Thus, basic communications can be achieved when TCP/IP are unavailable. Other embodiments are disclosed and claimed.

Abstract: A process for transalkylation of polyalkylated aromatic components can include providing a transalkylation reaction zone containing a transalkylation catalyst. A feedstock can be introduced into an inlet of the transalkylation reaction zone and into contact with the transalkylation catalyst. The feedstock can include a polyalkylated aromatic component derived from an aromatic substrate. The aromatic substrate can be supplied to the transalkylation reaction zone. The transalkylation reaction zone can be operated at temperature and pressure conditions sufficient to cause disproportionation of the polyalkylated aromatic component to produce a disproportionation product having a reduced polyalkylated aromatic content and an enhanced monoalkylated aromatic content. The disproportionation product can be withdrawn from the transalkylation reaction zone. Amounts of nitrogen containing compounds in the aromatic substrate can be monitored in a range of from 15 to 35 wppm by dry colorimetry.
Abstract: The present relates to a process for optimizing the recovery of unreacted monomers from a polymerization process, wherein said process comprises the steps of recovering a fluid stream generated by the separation of the polyolefin product from the polymerization fluid comprising unreacted monomers and optionally comonomers; contacting said fluid stream in an absorption zone with a scrub liquid comprising at least one C4-10 hydrocarbons, thereby absorbing at least a portion of the unreacted monomers in said scrub liquid; and withdrawing from said absorption zone (i) a vapor overhead comprising light gas and (ii) an absorber bottoms scrub liquid comprising said C4-10 hydrocarbons and said unreacted monomer; thereby recovering said unreacted monomer in said absorber bottoms scrub liquid comprising said C4-10 hydrocarbons.
Abstract: Apparatus for use in repairing, and methods of repairing, a door hinge of a vehicle includes use of a substitute hinge bracket and at least one pin configured to be received through at least one opening of a vehicle frame bracket. A locking portion of the at least one pin and a locking surface that defines an opening in the hinge bracket are configured such that the at least one pin is locked in a fixed position relative to the hinge bracket when assembled. Further, another repair apparatus includes a substitute pin having an interference portion for forming an interference fit with one or more surfaces defining an opening of a factory hinge bracket.
Abstract: A fluid processing assembly comprises a lumen for receiving at least one inlet stream and dispensing a primary product stream, and an energizing device for supplying energy to an energizable portion of the lumen. A primary product collection assembly is in fluid communication with the lumen for receiving the primary product stream. The energizable portion is positioned exterior to the primary product collection assembly. A pressurized gas source is downstream of the lumen. The pressurized gas source supplies pressurized gas to the primary product collection assembly for pressurizing at least a portion of the primary product collection assembly and the lumen.

Abstract: The invention relates to a process for preparing polyolefin in a loop reactor. The polymer is prepared by polymerizing olefin monomers in the presence of a catalyst to produce a polyolefin slurry while pumping said slurry through said loop reactor by means of a pump. The present process is characterized in that the catalyst is fed in the loop reactor at a distance to the pump. The invention allows production of the polymer with advantageous properties while leading to fewer blockages of the reactor.
