Title: Pipeline processing of still images adapted for real time execution of digital video effects
Inventor: DER HARRY
IPC: G06F3/048
Filed: 1995-03-20
Abstract: Two channels (A, B) or output of sequences of digital still images are input to a DVE system which has pipelined memory circuits (80, 82, 84) rather than frame buffers. The DVE system includes a DVE unit (52) which performs arbitrary three-dimensional, digital video effects on the two channels of input to provide a composite output sequence (C). The DVE system thus operates on sequences of digital still images rather than video signals. The DVE system is also adapted to prevent output upon receipt of a control signal (S1), which may indicate that an output pipeline is full. The DVE system also provides a control signal (S2) to prevent input when it cannot receive input or it is not providing output.
Patent CA-2187057-A1 (CA)
Inventor: KENNEY RICHARD E H
IPC: G09F1/14
Filed: 1996-10-03
Abstract: A print holder has two molded transparent plastic pieces united together each with an upright portion and a base having a lower side and a flank extending downwardly outwardly from a lower portion of the upright towards the lower side.  A central portion of the upright portion of one or both pieces is recessed inwardly to define a pocket for holding the print, having an upper opening.  The base portions form together a hollow base for capturing an inverted V-shape printed information carrier that has wings extending adjacent the inclining flanks of the base.  This allows display of information through the inclined base without requiring printing on the plastic.

Title: Method for the collection, analysis, measurement and storage of geographical data
Inventor: KIRCHNER WOLFRAM
IPC: G01C11/00
Filed: 1995-05-10
Abstract: The invention concerns a method for the collection, analysis, measurement and storage of geographical data, the aim being to guarantee user-relevant data handling and simplified availability in large, medium and small user centres and to ensures the optimization of existing components in digital stereo work stations with facilities for interactive overlay, truing and execution of digitally recorded landscape, planning and property data or land-register maps as well as the addition of alphanumeric data. This aim is achieved as shown in the figure by virtue of the fact that a topographic surface (zone 1) is recorded using aerial photography by an aircraft (2) whose position is determined by means of DGPS signals from satellites (3). A digital height model (4) is subsequently derived by data processing or calculated after the fourth operational step. From the topographic surface (zone 1) and the digital height model, including the known positions of the projection centres at the time the photograph was taken by the aircraft (2), and by mathematical transformation of the analogue aerial photo or of a digital aerial-photo scene, the digital orthophoto (5) is generated and made available to a potential user on a data-storage medium, thus enabling the potential user to add, to the digital orthophoto (5), vector/line graphics (6) and to make use of it depending on the task specification and necessary decision-making capacity which he, as mandator, has formulated.

Title: Hydrocarbon conversion
Inventor: BUCHANAN JOHN SCOTT
IPC: C10G35/06
Filed: 1995-09-27
Abstract: This is a process for upgrading a petroleum naphtha fraction. The naphtha (10) is subjected to reforming (16a, 16b, 16c) and the reformate is cascaded to a benzene and toluene synthesis zone (18) over a synthesis catalyst comprising a molecular sieve of low acid activity. The preferred molecular sieve is steamed ZSM-5. The benzene and toluene synthesis zone (18) is operated under conditions compatible with the conditions of the reformer such as pressures of above about 50 psig (446 kPa) and temperatures above about 800 ~F (427 ~C). In one aspect of the invention, the benzene and toluene synthesis catalyst includes a metal hydrogenation component such as cobalt, nickel, platinum and palladium. In one mode of operation, the benzene and toluene synthesis catalyst replaces at least a portion of the catalyst of the reformer. The process produces a product containing an increased proportion of benzene and toluene, and reduced proportion of C8 aromatics, particularly ethylbenzenes, as compared to the reformate.

Title: Molecular tagging system
Inventor: BRENNER SYDNEY
IPC: C12N15/10
Filed: 1995-10-12
Abstract: The invention provides a method of tracking, identifying, and/or sorting classes or subpopulations of molecules by the use of oligonucleotide tags.  Oligonucleotide tags of the invention each consist of a plurality of subunits 3 to 6 nucleotides in length selected from a minimally cross-hydridizing set.  A subunit of a minimally cross-hybridizing set forms a duplex or triplex having two or more mismatches with the complement of any other subunit of the same set. The number of oligonucleotide tags available in a particular embodiment depends on the number of subunits per tag and on the length of the subunit. An important aspect of the invention is the use of the oligonucleotide tags for sorting polynucleotides by specifically hybridizing tags attached to the polynucleotides to their complements on solid phase supports. This embodiment provides a readily automated system for manipulating and sorting polynucleotides, particularly useful in large-scale parallel operations, such as large-scale DNA sequencing, mRNA fingerprinting, and the like, wherein many target polynucleotides or many segments of a single target polynucleotide are sequenced simultaneously.

Title: Paint spray booth and supply plenum arrangement
Inventor: COLE DAVID J
IPC: B05B15/12
Filed: 1995-11-06
Abstract: An air supply plenum for a paint spray booth (20) includes a housing with separating walls (40, 42) positioned between the ceiling (28) and a filter support panel (30) of the plenum housing. The air flow supplied to the paint spray booth area (56) is divided by the walls into three distinct flows: (1) a central flow air, through which the article (36) to be painted travels in the paint spray booth; (2) two outer greater flow areas where the operators and/or equipment (37) for applying paint to the article to be painted are located.  Filters (38) are positioned in the supply plenum arrangement adjacent and above the filter support panel separating the plenum and paint spray booth.  The filters run longitudinally along the length of the plenum and between the separating walls. The positioning of these filters in this manner minimizes the amount of turbulence of the flow provided to the spray paint booth.
