Abstract: Providing fluid to an internal delivery site of a patient includes moving the fluid from a fluid reservoir through a conduit and through a delivery device at the delivery site while maintaining the fluid at a predetermined pressure. The delivery device may comprise an inflatable balloon with apertures formed in its periphery for directing the fluid into the vessel walls. Pressurized fluid is provided through the apertures of the balloon to the vessel wall. The pressure is automatically controlled to avoid both pressure spikes and unacceptable deflation of the balloon during administration of the fluid. A further feature includes comparing the pressure with the volume infused and in the event that pressure decreases while the volume infused increases beyond certain limits, the delivery of the fluid is stopped. Further features include a timer for limiting the inflation time of the delivery device and a volume detector for controlling the amount of fluid delivered. In one described embodiment, a pneumatic driver system is used to pressurize the fluid.

Abstract: A rotor assembly for processing a liquid comprises a rotor body (52) which is rotatable about an his of rotation (R). The rotor body comprises: a first cavity region for containing a liquid, said first cavity region having an outer wall at an alpha radial distance from said axis of rotation (R); a second cavity region; and liquid diverting means for diverting substantially all of said liquid from said first cavity region to said second cavity region when said rotor body (52) is rotated in a manner imparting momentum to liquid contained within said first cavity region and then rapidly stopped. The liquid diverting means has an influent end positioned at said alpha radial distance, said influent end being in fluid communication with said first cavity region, and an effluent end positioned at a beta radial distance from said axis of rotation, said effluent end being in fluid communication with said second cavity region and said beta radial distance being less than said alpha radial distance. The liquid diverting means defines a liquid flow path between said influent end and said effluent end, said liquid flow path corresponding to the direction in which said rotor body (52) is rotated about said axis of rotation. The liquid diverting means includes backflow preventing means to prevent backflow of liquid into said first cavity region.

Abstract: An apparatus and method for extending the range of a digital data network by enhancing skew control. The apparatus is a circuit for use in a network interface unit. The apparatus measures the distance of the network interface unit from the head-end retransmission unit of the network by transmitting a series of signal packets on the network and counting the time it takes for the packets to be received back at the interface unit. All transmissions on the network take place with reference to a timing mark transmitted by the head-end unit at a regular interval. The apparatus sends the first in the series of signal packets at a pre-determined pre-skew interval before the timing mark. The apparatus counts the number of clock cycles after the timing mark before the signal packet is received back at the network interface unit. If the signal packet is not received back at the network unit within a pre-determined number of clock cycles, the apparatus sends a new signal packet at a new, larger pre-skew interval before the timing mark and again counts the clock cycles after the timing mark. This process is repeated until a signal packet is successfully received back at the network interface unit. Once a signal packet is successfully received back at the network interface unit, the pre-skew value at which the packet was sent and the value of the number of clock cycles after the timing mark at which the packet was received back is stored in the interface unit and all subsequent transmissions by that unit on the network are done at an interval before the timing mark defined by the stored skew value.

Abstract: A forced intra-frame coding method in which video data is coded in the vertical direction of a frame and the coding is performed for forcibly intra-frame coded macro block (MB) lines set to have a predetermined vertical interval. Whenever the coding for respective frames is finished, the macro block lines are shifted downward by one macro block so that the original image is restored relatively rapidly. Furthermore, the coding direction of macro blocks is set to be vertical so that the amount of data for respective macro blocks stays uniform and the transmission buffer of a coder is easily controlled.

Abstract: A digital Wiener filtering method is proposed which applies motion compensation by successive approximations of increasing resolution to determine displacement vectors for two successive image frames, a vector defining a real displacement only being applied to a block of one of the frames when the mean absolute error associated with that vector is not greater than a given fraction of the mean absolute error between that block and the corresponding block of the other frame. The current frame is then filtered block-by-block, with the blocks overlapping. In this filtering, each block is a 3D volume of pixels from the current frame and blocks selected from the preceding and succeeding frames so as to correspond according to the displacement vectors. In one embodiment, the filtering comprises applying a 3D FFT to convert to a power spectrum in the frequency domain, followed by attenuation according to a Wiener filter and conversion from the frequency domain by the inverse FFT.

Abstract: The control device is for the multiple telescopic jib of a loading crane. There are piston-cylinder units (4.1-4.6) between adjacent extenders. The cylinders (6.1-6.6) of these units have lines on both sides connecting them to the preceding and subsequent cylinders. The cylinder of the piston-cylinder unit pivoted to the fixed jib sector is connected on the piston side via an outward line (9.1-9.6) to a pressure source (10) to extend it from its withdrawn position. The piston-side operating pressure of each subsequent unit is reduced. The pressure reduction for the cylinder of a retracted unit is greater relative to that of the preceding unit when the piston rod is extended.

Abstract: A method for recovering iron chloride, aluminium chloride and calcium chloride from silicon and ferrosilicon or from residues which contain silicon and/or ferrosilicon and metal chlorides and optionally copper and/or copper compounds. These materials are leached with CHl or CHl + FeCl₃/FeCl₂ solution, whereafter the solid silicon or ferrosilicon residue is removed from the leach solution together with any copper. Fe²⁺ in the leach solution is then oxidised to Fe³⁺ whereafter the leach solution is subjected to liquid-liquid extraction by means of an organic phase containing n-tributyl phosphate dissolved in a hydrocarbon solvent in order to extract FeCl₃ and at least a part of any CaCl₂ from the leach solution. FeCl₃ and any CaCl₂ are stripped from the organic phase by water and the remaining solution is concentrated by evaporation and adding HCl gas to the solution in order to selectively precipitate AlCl₃.6H₂O and AlCl₃.6H₂O is then recovered from the solution by filtration.

Abstract: Line cards provide an input/output interface between synchronous communication channels and an asynchronous network. The input line card translates information received from the synchronous communication channels into packets for transmission to the asynchronous network. Each line card generates and stores packets corresponding to a time frame associated with the synchronous communication channels. A sequence is selected for the sequential transmission of packets by each input line card to the asynchronous network. The cumulative number of packet collisions that would occur at each output line card during the predetermined time frame is determined. If the cumulative number of collisions exceeds a predetermined delay threshold, the number of packets actually transmitted to the system is reduced preferably by denying service to new call origination requests. This technique keeps the maximum cumulative collisions for each output line card within the predetermined delay threshold.
