Patent number: 7025938Abstract: The partially condensed fluid recycle stream of a fluidized bed polyolefin reactor operating in the condensing mode is split into two portions by a stream splitter. In a preferred mode, the smaller stream from the splitter contains a higher ratio of liquid to gas than the larger stream. One portion of the split stream is injected below the fluidized bed and the other, preferably with enhanced liquid content, is injected into the fluidized bed at a level above the product withdrawal level. Regulation of liquid injection above the product withdrawal level, as a function of liquid in the product discharge tanks, reduces the liquid in the product discharge system, resulting in improved discharge cycle times and more efficient conservation of monomer and other materials which might otherwise be lost in the discharge process.Type: GrantFiled: October 12, 2004Date of Patent: April 11, 2006Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: Robert Darrell Olson, Timothy Joseph Howley

Patent number: 6886507Abstract: An exhaust valve for a two-cycle engine. The exhaust valve includes a valve body and an actuator. The valve body, in turn, includes a valve insert and a shaft extending from the valve insert. A substantially axial slot may be defined on an upper surface of the valve insert. The actuator may include an actuator housing, the piston, an actuator spring, and an actuator cover. in the embodiment shown, the actuator housing defines a plurality of orifices and feelingly accommodates the piston. The piston may be mechanically connected to the valve body shaft and is biased toward a front surface of the actuator housing by a spring. The actuator cover may accommodate one end of the spring and cooperates with the actuator housing to define a generally cylindrical cavity therein.Type: GrantFiled: April 4, 2003Date of Patent: May 3, 2005Inventor: Darrell Olson

Patent number: 4783348Abstract: Disclosed is a method and apparatus for continuously forming and depositing a layer of monomolecular amphiphilic molecules on a substrate. The present invention includes an apparatus and method for transferring and compressing an uncompressed molecular layer from one liquid surface region in a tank to another adjacent liquid surface region by using non-moving or static mechanical components which do not come into direct contact with the monomolecular layer. The present invention includes a method and apparatus which permit the continuous and simultaneous draining and replenishing of the liquid in the tank while maintaining the liquid surface level constant. The continuous replacement of the liquid in the tank with clean liquid reduces the level of contamination of the liquid in the tank. In addition, the level, as well as the type of contamination of the liquid, does not vary significantly with time.Type: GrantFiled: November 24, 1986Date of Patent: November 8, 1988Assignee: Daleco Research DevelopmentInventors: Otto Albrecht, Meir Bartur, Vladimir Rodov
