Title: Twisted tape heat exchanger
Inventor: CHELUGET ERIC
IPC: F28F13/12
Filed: 2002-01-16
Abstract: It is known to use static mixers in heat exchange devices.  Typically the static mixers are comprised of a number of short elements having a high degree of twist per unit length. These types of devices tend to produce high pressure drops across the device leading to phase separation and possibly inversion when used with two phase systems. The present invention seeks to overcome this drawback by using a continuous twisted tape shear device having a relatively low twist ratio.

Title: Method and apparatus for transmitting video and graphics in a compressed form
Inventor: EDMONDS JEREMY S
IPC: H04N7/24
Filed: 2000-10-27
Abstract: A method and apparatus for compressing and transmitting both video and graphics portions of an interactive program guide (IPG). For an IPG that comprises a graphics portion and at least one video portion, the inventive system separately encodes the video portion and the graphics portion.  The video portion is slice-base encoded using a predictive encoder (408), e.g., an MPEG encoder, that produces a bitstream comprising intra-coded picture slices and predictive-coded picture slices. The graphics portion is separately slice-base encoded using a guide encoder (416) to produce encoded slices of the graphics image. The encoded slices of the graphics portion can be stored in a database (418) and recalled as needed for transmission.  To transmit an IPG, a transport stream is created containing the intra-coded and predicted picture streams as well as the encoded slices that comprise a graphics image that is to be included in the IPG.  The receiver reassembles the components of the IPG into a comprehensive IPG.
