Patent CA-2266057-A1 (CA)
Inventor: HOLLEY JOHN ERNEST FOSTER
IPC: G01N33/543
Filed: 1997-09-11
Abstract: An apparatus for measuring optical characteristics of liquid samples, clinical samples for example, has an optical head (21) which is adapted to scan past a rack (12) of sample containers first in one direction and then in the opposite. The optical head has reference and test light sources (22) and corresponding light detectors (28) and separate optical paths are provided in the head for developing reference and test beams passing through the scanned samples. A fixed band pass filter is provided in the reference path and a filter wheel with a plurality of different band pass filters is provided in the test path, the apparatus being arranged to index the requisite filter into the test path in dependence upon the results of the reference scan. The optical head is driven by a reversible stepper motor (26) via a toothed drive belt (27) and this enables the output signals from the detectors to be correlated to the specific samples in the rack. The reference and test signals from the detectors are processed so that signal aberrations due to artefacts (e.g. scratches) in the sample containers are neglected, and results are derived dependent upon both the reference and test scans and are printed out on an integral printer. The apparatus is compact (it can be fitted into a briefcase) and requires no special skills for its utilization, being programmable for performing specific tests of a predetermined kind by use of an integral bar code reader.

Title: Integrated hydrotreating and hydrocracking process
Inventor: KALNES THOMAS N
IPC: C10G47/18
Filed: 1999-09-03
Abstract: A hydrocarbonaceous feedstock is converted in an integrated hydrotreating and hydrocracking process by combining with a hot hydrocracking zone effluent recycle stream containing hydrogen, and the mixture is passed to a denitrification and desulfurization reaction zone to produce hydrogen sulfide and ammonia to thereby clean up the fresh feedstock. The resulting hot, uncooled effluent from the denitrification and desulfurization zone is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrotreating zone with a hydrogen-rich gaseous stream to produce a vapor stream comprising hydrogen, hydrocarbonaceous compounds boiling at a temperature below the boiling range of the fresh feedstock, hydrogen sulfide and ammonia, and a liquid hydrocarbonaceous stream wherein at least a portion of this liquid stream is then passed to a hydrocracking step to produce the hot hydrocracking effluent recycle stream which is passed back to the hydrotreating zone.

Patent CA-2300860-A1 (CA)
Title: Press system for reaction injection moulding
Inventor: MCNALLY DOUGLAS J
IPC: B29C33/36
Filed: 1998-08-19
Abstract: The mold press includes a drive arrangement for controlling press movement and closure force. The drive arrangement includes a pair of generally identical drive units (76) connected between upper and lower press plates (36, 51) adjacent opposite longitudinal ends of the press. The drive units (76) in a preferred embodiment each employ a ball-screw drive arrangement (71). The screw shaft (74) extends vertically between the top and bottom press plates. A screw shaft engages a ball nut mounted on one press plate, typically the bottom press plate (51) which is disposed for movement toward and away from the top press plate (36). A first high speed drive arrangement employing a first electric motor is coupled to the screw shafts for effecting high speed opening and closing of the bottom press plate. A second low-speed driving arrangement including a second electric motor is drivingly connected to the ball-nut assemblies for permitting low-speed but high-torque driving of the nut units (76) for final closing of the press and application of the desired press force. Each drive unit has the screw shaft resiliently supported for limited axial displacement relative to the upper press plate so that, when the second drive system is activated to effect final closure of the mold, one or the other of the screw shafts can be axially displaced a small amount if necessary so as to permit full closure between the opposed upper and lower mold parts (31, 32) even though irregularities may cause one longitudinal end of the mold parts to contact and close prior to the other longitudinal end.

Title: A ferroelectric data processing device
Inventor: GUDESEN HANS GUDE
IPC: H01L27/06
Filed: 1998-08-13
Abstract: In a ferroelectric data-processing device for processing and/or storage of data with active or passive electrical addressing a data-carrying medium are used in the form of a thin film (1) of ferroelectric material which by an applied electric field is polarized to determined polarization states or switched therebetween and is provided as a continuous or patterned layer above and adjacent to electrode structures in the form of a matrix, the electrode structures being mutually isolated by an electrical isolating material (6). A logic element (4) is formed in the thin film (1) along the side edges of an y electrode (3) and down to the x electrode (2) at the overlap.      The logic element (4) is addressed by applying to the electrodes (2,3) a voltage greater than the coercivity field of the ferroelectric material.      Dependent on the polarization state and the form of the hysteresis loop of the ferroelectric material a distinct detection of the polarization state in the logic element (4) is obtained and it may also be; possible to switch between the polarization states of the logic element, which hence may be used for implementing a bistable switch or a memory cell.    The data-processing device according to the invention may be stacked layerwise if the separate layers are separated by an electrical insulating layer and hence be used for implementing volumetric data-processing devices.
