Title: Lubrication of a hermetic carbon dioxide compressor
Inventor: BUNCH RICK L
IPC: F04C18/356
Filed: 2003-06-10
Granted: 2007-03-13
Abstract: A hermetic compressor which uses carbon dioxide as the working fluid. The compressor includes a motor and a compression mechanism operatively coupled by a drive shaft supported by a bearing. The drive shaft includes a radially extending bore in fluid communication with an oil supply passageway in the drive shaft and the outer periphery of the drive shaft. An oil accumulating cavity is located beneath the radially extending bore in which oil is stored during compressor shutdown to provide oil to bearing surfaces upon compressor startup. An oil return system includes a chamber located at one end of the drive shaft and an oil return passageway extending from the chamber to an annulus formed between the bearing and the drive shaft. The oil in the annulus lubricates the bearing and drive shaft interface. A discharge tube is provided having means for aspirating oil from an oil containing sump when the oil in the oil sump reaches a particular level.

Abstract: A method and mechanism for automating user input in an interactive television system. An interactive application is conveyed concurrently with a broadcast programming stream in an interactive television system to a receiver. The interactive application is configured to provide added content to a television viewer upon a request by the viewer. In order to request the display of the available added content, a viewer may provide an indication that the use of a script is desired. Subsequently, a script corresponding to the interactive application is utilized to provide input to the interactive application in lieu of the viewer actively providing the input necessary to display the added content. In addition, a viewer may configure the receiver to indicate default preferences for the use of scripts. The receiver may then utilize a standardized script to provide input to interactive applications having added content available for viewing. Further, a corresponding program, interactive application, added content, and script may be received and stored on a mass storage device. Subsequently, the stored material may be retrieved for display and execution.

Title: A jacket for use with a lock latch, a lock latch incorporating the same and a slide incorporating the lock latch and jacket
Inventor: LE BAOLOC
IPC: A47B88/493
Filed: 2002-08-15
Granted: 2010-03-30
Abstract: A jacket for a lock latch, a lock latch incorporating such a jacket that allows a second slide member of a slide to engage and couple a first slide member of the slide without requiring manual manipulation of the lock latch, and a slide incorporating the same are provided. The jacket is slidably coupled to the lock latch which is coupled to the second slide member and is slidably moveable between a first position and a second position along the lock latch. When the second slide member is retracted relative to the first slide member during coupling of the second slide member to the first slide member, the jacket moves to the first position preventing the lock latch from interlockingly coupling with the first slide member. When the second slide member is extended relative to the first slide member, the jacket moves to a second position allowing for the interlocking coupling of the lock latch with the first slide member.

Title: A static mixer
Inventor: MATHYS PETER
IPC: B01F5/04
Filed: 2004-03-08
Granted: 2011-08-23
Abstract: The static mixer (1) for a low viscosity fluid (20) contains inbuilt devices (10) effective for mixing, which are arranged in a pipe (3) or in a container conducting the fluid. The geometry of the inbuilt devices is largely that of a base structure. The inbuilt devices include structure elements (11, 11', 12) in the form of flat, folded or curved sheet metal-like flow obstacles as well as constrictions lying therebetween. A flow of the first order can be achieved by inbuilt devices in the form of the base structure and is a flow mixing the pipe contents globally in downstream mixing regions. The structure elements of the base structure can be described as segments, plates and/or vanes. The structure elements - called "primary flow obstacles" (11, 11', 12) in the following - are geometrically modified at surfaces and/or at edges. Local flows of the second order can be induced by these modifications which are superimposed on the flow of the first order and so improve the mixing quality. Radial and axial inhomogeneities in the fluid are namely better compensated than by the flow of the first order. Secondary flow obstacles (11a, 11a', 12a) form the modifications by which the turbulence is locally intensified and/or backflows are induced.
