Abstract: A naphtha feedstock is catalytically reformed in a combination sequence comprising a continuous-reforming zone, consisting essentially of a moving-bed catalytic reforming zone with continuous regeneration of catalyst particles, followed by a zeolitic-reforming zone containing a catalyst comprising a platinum-group metal and a nonacidic zeolite operating on the effluent from the continuous-reforming zone. The unique process combination permits higher severity, higher BTX aromatics yields and/or increased throughput in the continuous-reforming zone, thus showing surprising benefits over prior-art processes, and is particularly useful in upgrading existing moving-bed reforming facilities with continuous catalyst regeneration.

IPC: G05D16/20
Filed: 1996-09-06
Abstract: The invention concerns a process for automatically controlling a hydraulic servo-valve with a hydraulic slide valve (1) which is displaced by a rotary actuator (12). The process involves a first loop (2, 5, 11, 12, 4) for automatically controlling the delivery as a function of the measurement of the angular position of the rotary actuator, and a second automatic control loop (1, 3, 6, 21, 22, 23, 11, 12, 4, 2) with variable control as a function of the pressure measurement. The invention is characterized in that the first automatic control loop is a proportional action loop whose increase (K¿pa?) is constant for values of the absolute pressure difference value (.epsilon.¿p?) which are less than at least a threshold value, then varies in an increasing manner for values of the absolute pressure difference value (.epsilon.¿p?) which are greater than this first threshold.

Patent CA-2236616-A1 (CA)
Title: Detection of nucleic acids by fluorescence quenching
Inventor: LINN C PRESTON
IPC: C12Q1/68
Filed: 1998-05-04
Abstract: Single-stranded signal primers are modified by linkage to two dyes which form a donor/acceptor dye pair. The two dyes are positioned in sufficiently close spatial proximity on the signal primer that the fluorescence of the first dye is quenched by the second dye. The signal primer may further comprise a restriction endonuclease recognition site (RERS) between the two dyes. As the signal primer is initially single-stranded and remains single-stranded in the absence of target, the restriction endonuclease recognition site is not cleavable or nickable by the restriction endonuclease. In the presence of target, however, signal primer and the restriction endonuclease recognition site are rendered double-stranded and cleavable or nickable by the restriction endonuclease. Cleavage or nicking separates the two dyes and a change in fluorescence due to decreased quenching is detected as an indication of the presence of the target sequence or of target sequence amplification.

Abstract: Disintegratable tablets for oral administration are made from a three pellet system. One type of pellet contains drug, another is soft and another includes a disintegrant allowing the tablet to disintegrate in the stomach. The drug pellets are preferably coated, for instance with a controlled release binder. The soft pellets preferably contain an ester of a fatty ester. The disintegratable pellets preferably comprise a water-insoluble inorganic powder, such as barium sulphate, iron oxide, magnesium oxide or calcium carbonate. The soft pellets deformed during the tabletting procedure to minimise damage to the drug containing pellets, for instance minimising disruption of the coating. The disintegrant pellets mean the release characteristics from the drug pellets are retained.

Title: Editing image data
Inventor: SAVOIE CHARLES
IPC: G11B27/034
Filed: 1998-07-28
Abstract: An image data editing system is arranged to capture source image clips at full definition in response to edit decision lists. The system conforms the captured material to produce output image clips in response to the edit decisions defined in the list used to capture the source material. Association identifiers are applied to many edit decision lists and the capturing process isconfigured to capture all source material for all of the edit decision lists having the same association identifier. Each associated edit decision list may be conformed independently and manipulations may be performed with reference to the captured source material. However, when many output reels are required derived from a collection of source material, it is only necessary to capture the source material once.
