| 20080279757 | POLYMER HALOGENATION PROCESS WITH CATALYST RECOVERY - The present invention relates to a method for recovering antimony catalysts wherein the formation of insoluble solids is reduced. | 11-13-2008 |
| 20090054709 | Process For Producing N-Propyl Bromide or Other Aliphatic Bromides - A process for the production of an aliphatic bromide in which the bromine atom is attached to a terminal carbon atom, which process comprises continuously feeding olefin having a terminal double bond, gaseous hydrogen bromide, and a molecular oxygen-containing gas into a liquid phase reaction medium comprised of aliphatic bromide to cause anti-Markovnikov addition of HBr to terminal olefin, the feeds being proportioned and maintained to provide a molar excess of hydrogen bromide relative to terminal olefin in the range of about 1 to about 5 percent, and a molar ratio of molecular oxygen to terminal olefin of less than 0.005. The process is especially suited for production of n-propyl bromide. | 02-26-2009 |
| 20090240091 | SEPARATION AND/OR RECOVERY OF PROPYL BROMIDE - Described is a process for separating an organic phase comprising mainly propyl bromide from a crude reaction mixture formed by free-radical catalyzed hydrobromination of propylene with hydrogen bromide. The process comprises (A) feeding cold water into an upper or mid-portion of a packed column; (B) concurrently feeding the crude reaction mixture into an upper portion and/or mid-portion of the column so that the water contacts the crude reaction mixture; to form a mixture of (i) an acidic aqueous phase comprising aqueous hydrogen bromide and (ii) an organic phase comprising propyl bromide; (C) withdrawing the resultant phases from said column, at a rate comparable to the feeds being made into the column; and (D) separating the phases to form an upper acidic aqueous phase comprising aqueous hydrogen bromide superposed on a lower liquid organic phase comprising propyl bromide, and separating these upper and lower phases from each other. | 09-24-2009 |

| 20100102010 | Vortex generator for a fluid filter - A vortex generator for use in a fluid filter operable in both a normal filtering mode and a back flushing mode. The vortex generator including a flapper valve that moves between an open position and a closed position in correspondence to the direction of fluid flow through the fluid filter. In the open position, fluid is permitted to flow through openings formed in a base of the vortex generator. In the closed position, fluid is prevented from flowing through the openings. | 04-29-2010 |

| 20090116961 | Ceiling Fan with Heating Assembly - An apparatus for distributing heated air to an environment comprises a ceiling fan assembly secured to a heating assembly. The ceiling fan assembly comprises a plurality of rotatable blades arranged substantially in a horizontal plane to drive airflow in a desired direction when the blades are rotated. The heating assembly comprises a heating element and a power supply for energizing the heating element to produce heat, whereby air driven by the ceiling fan contacts the heating element and passes into the environment. A lighting assembly and a guard may be included. | 05-07-2009 |
| 20100316495 | Lighting and Heating Assembly for a Ceiling Fan - A lighting and heating assembly is provided. The lighting and heating assembly is configured for mounting to an existing ceiling fan. The lighting and heating assembly includes a lighting assembly for distributing light and a heating assembly for providing heat to the air circulated by the ceiling fan. The lighting assembly is attachable to the ceiling fan and has the heating assembly detachably connected thereto, which allows the lighting assembly to be used without the heating assembly. Additionally, the lighting and heating assembly is adjustable such that the lighting assembly and/or heating assembly are repositionable at desired locations in relation to one another and the air flow generated by the ceiling fan. | 12-16-2010 |
