Title: Hydrocarbon gas processing
Inventor: CAMPBELL ROY E
IPC: C07C7/04
Filed: 1989-05-16
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE           A process for the recovery of ethane and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed.  The stream is divided into first and second streams.  The first stream is cooled to condense substantially all of it and is thereafter expanded to a pressure below that of the distillation column.  After expansion, the cooled first stream is directed in heat exchange relation with a warmer distillation stream rising from fractionation stages of the distillation column.  The warmed first stream is then separated to provide a cold vapor and a liquid stream. The liquid is supplied to the column at a first mid-column feed position and the cold vapor is supplied to the column at a second mid-column feed position. The second stream is expanded to the column pressure and is then supplied to the column at a third mid-column feed position.  The distillation stream is cooled by the first stream sufficiently to partially condense it.  The partially condensed distillation stream is then separated to provide volatile residue gas and a reflux stream feed.  The reflux stream feed is supplied to the column at a top column feed position.  In instances where the second stream is expanded in a work expansion machine, any condensation formed prior to work expansion is combined either in whole or in part with the first stream prior to cooling and/or expansion, or supplied either in whole or in part to the column as a condensed stream at a fourth mid-column feed position, or some combination thereof.  The temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the C2+ components is recovered.

Title: Image interpolator for an image display system
Inventor: GONZALEZ-LOPEZ JORGE
IPC: G06T3/40
Filed: 1989-06-20
Granted: 1993-02-02
Abstract: IMAGE INTERPOLATOR FOR AN IMAGE DISPLAY SYSTEM        ABSTRACT OF THE DISCLOSURE     An  image  interpolator  implements  an  interpolation function providing real time, continuous zoom capability to an image display system. Output image pixels are obtained by interpolating the values of the color or intensity of the 2x2 matrix of pixels surrounding the point on the input image.   The  preferred  embodiment  employs  a  bi-linear interpolation algorithm implemented in the form of cascaded one-dimensional   interpolation circuits.    Magnification control is established so that a unit increment of the zoom controller,  such as a cursor on a tablet,  results  in a constant  increase  in  the  degree  of  magnification.   The coefficients required for the interpolation are-generated in real  time  avoiding  the  need  for  time  consuming  table look-ups.

Abstract: A method for communicating with a plurality of hosts connected to an X.25 network and for selectably using a character as a control character or a data character. Each character received from the X.25 network is inspected to determine if it is one of a set of resened characters. If so, the character is encoded before being sent to its final destination. Data intenderl for the X.25 network is inspected for the presence of a predetermined control character. If the control character is present, the next character is inspected to determine whether it is a command character or an encoded data character. If this next character is an encoded data character, it is decoded and provided to the X.25 network. If this next character is a command character, then the command is executed. The method allows the use of any character as either a command character or data character. Data transfer between the DTE and DCE is assigned a PAD and a virtual channel number which corresponds to a particular host on the X.25 network. The channel number may, but need not, be the same as the X.25 device address for that host. The method therefore allows the DTE and DCE to simultaneously communicate with a plurality of X.25 hosts over a single telephone line or physical transmission link.

Abstract: The application relates to a process for synthesising carbonic allyl esters from polyhydric alcohols, which are reacted with diallyl carbonate in the presence of a basic catalyst, which can be chosen from sodium hydroxide, sodium carbonate, sodium alcoholate, organic bases or basic ion exchange resins.The final products obtained differ according to the ratio of the components of the starting mixture. Thus, in the case of diols with a diallyl carbonate/diol ratio greater than or equal to 10, the resultant product is constituted by the bis allyl carbonate of the diol together with a quantity of less than or equal to 10% of oligomers represented mainly by dimers. If the ratio is less than 10, the percentage of oligomers rises until, in the case of an approximately stoichiometric ratro, it reaches a value close to 70% of the reaction product.
