Abstract: An improved method for the safe transportation and handling of hydrogen fluoride from a point of origin to a desired destination. The method involves adding, at the point of origin, a sulfone, having the general formula R-SO2-R' wherein R and R' are monovalent hydrocarbon alkyl or aryl substituents containing from 1 to 8 carbon atoms, to hydrogen fluoride to form a mixture containing an amount of water of no more than 30 weight percent of the total weight of the hydrogen fluoride in the mixture. The mixture also includes a weight ratio of sulfone to hydrogen fluoride in the range of from 1:100 to 100:1. The mixture is then transported to the desired destination. At the desired destination, the mixture is separated into a sulfone phase, comprising sulfone and containing less than 20 weight percent hydrogen fluoride based on the total weight of the sulfone phase, and a hydrogen fluoride phase comprising hydrogen fluoride and containing a weight ratio of sulfone to hydrogen fluoride of less than 2:100. The sulfone phase is then returned to the point of origin to reuse as sulfone.

Abstract: An intravascular material delivery dilation catheter ( 10) having a pair of longitudinally spaced inflatable balloons (20, 22) with a drug delivery region (26) defined therebetween. The catheter is ideally suited for use after a PTCA procedure, wherein the proximate balloon (20) seals the blood vessel while the distal balloon (22) is uniquely contoured when inflated to define fluid communication paths (60) therepast and proximate a blood vessel (54) to be treated. The distal balloon (22), when inflated, has four lobes but could also be textured. Each lobe is separated from the next by a groove, which groove in combination with the blood vessel inner wall forms a fluid communication path therebetween. Upon inflation of both balloons (20, 22) in a blood vessel (54), a medicament such as heparin can be injected, via the drug delivery region (26) between the inflated balloons (20, 22), wherein the medicament flows past the distal balloon (22) at a selected rate. Accordingly, a medicament can be injected directly to a treatment site rather than injected as a bolus dose, thus, a smaller dosage may be employed to minimize side effects. Alternatively, perfusion can be accomplished by only partially inflating the proximate balloon (20) to constrict flow therepast, or eliminating the proximate balloon (20) entirely, where the drug delivery region is disposed upstream of the contoured distal balloon (22).

Each customer terminal (2) has a first service unit means for relatively narrow bandwidth traffic and a second service unit means for relatively wider bandwidth traffic. Each customer terminal (2) has a demultiplexer (22) arranged to receive multiplexed downstream traffic from the network (18), and to segregate the traffic between the first and second service unit means. Each customer terminal (2) has control means for generating relatively narrow bandwidth control signals for upstream transmission over the network, the second terminal unit means (BTS(1) to BTS(n-1)) of the line terminal (1) being responsive to the control signals from a given customer terminal (2) to control the transmission of the relatively wider bandwidth traffic to that customer terminal. The downstream transmission is by TDM and the upstream transmission is by TDMA.

Abstract: The present invention provides a method (600) and system (100) for predicting a differential vector field. The method and system enable the detection and encoding of an area where motion compensating the past image frame to the current image frame, fails. Based on the DFD signal, the present invention detects regions where the motion compensation has failed (102). The boundaries of these regions are encoded and sent to the decoder (104). The intensity values contained in this region, by the current intensity frame, are also encoded and sent to the decoder. Based on the decoded region boundaries, the decoder decodes the intensity values and places them into the correct regions.
