Title: Process and device for investigating particles situated in a gas
Inventor: BURTSCHER HEINZ KURT
IPC: G01N27/66
Filed: 1994-02-23
Abstract: A process for investigating particles situated in a gas in which a gas stream is guided past a miniaturized UV excimer radiator. Particles situated in the gas are ionized and subsequently filtered out, and the resultant photoelectrically induced current is measured.   Since particles from different sources (petrol engine, diesel engine, cigarette smoke) exhibit a wavelength dependence which is characteristic of the source, by measurements at at least two wavelengths, which is readily possible when using UV excimer radiators with different gas fillings, pollutants can be detected according to the source.

Title: High-Definition Digital Video Processor For Telecines
Inventor: BRETT STEVEN
IPC: H04N9/11
Filed: 1994-04-11
Abstract: A digital video processor for correcting video color and other attributes such as pixel location and sharpness has an architecture in which only the pixels and/or regions of a video picture to be modified have any processing applied to them, so that most pixels, which are unmodified, remain free from any corruption. It identifies pixels to be modified by means of lookup tables which can be loaded for each frame with data indicating attributes which are to be present in a pixel if that pixel is to be selected for modification. The processor has multiple channels, with precedence logic to control the priority order of the channels, in order to apply the particular modification increments associated with only one channel, in the event that more than one set of selection attributes are applicable to a given pixel. <IMAGE>

Title: Mobile satellite communication system
Inventor: NONAMI TAKAYUKI
IPC: H04B7/185
Filed: 1994-06-08
Abstract: The mobile communication system monitors the absolute location of a mobile station so as to reduce the traffic in communication lines arising from location registration. The satellite base stations are each equipped with a navigation signal generator for issuing navigation signals. The mobile station detects its absolute location on the ground based on the navigation signals received from the satellite base stations (or from dedicated GPS satellites) and executes its location registration procedure by use of identification data (communication zone ID) associated with the communication zone in which it lies and which is determined by the thus detected absolute location data. Location data can also be transmitted via switching centres located on the earth and transmitted via the satellite stations. <IMAGE>
Patent GB-2282728-A (GB)
Title: Scanner
Inventor: MATSUMURA YUKINORI
IPC: B23K26/066
Filed: 1993-05-07
Abstract: To implement a high speed scanning, the positions in the direction Y ("O") where no main scanning is executed are removed in an image plane. Only the positions in the direction Y ("1") where the main scanning is executed are stored in advance. On the other hand, the position in the direction Y which is currently scanned by the main scanning is detected. Then, based on this result, the next position in the direction Y to be main scanned ("1") is read from the stored information. The next main scanning of the position in the direction Y thus read is started as soon as the current main scanning is complete, thus making it possible to execute the scanning at a higher speed. <IMAGE>

Title: Measuring position of edge of workpiece
Inventor: YAMAOKA NAOJI
IPC: G06T5/00
Filed: 1994-11-18
Abstract: To measure the position of an edge of a workpiece d, a projector 1 directs a flat beam of light onto the workpiece and a sensing device 2 images the line of light S1 on the workpiece. In the image, coordinates of the end (A1) of the line S1 adjacent the edge are determined. Coordinates of centres of gravity (G3, G4) of the line S1 in two windows (W3, W4) along a straight portion of the line S1 are determined to obtain the equation of a straight line (L1) passing through both centres of gravity. Coordinates of the crossing point (Q1) of line (L1) and a second straight line (L2) passing through the end point (A1) provide a reference point indicative of the position of the edge. A reference point indicative of the position of the common edge of two inclined regions of a workpiece is determined as the crossing point of lines (S1a, S1b) through centres of gravity of two windows set along respective lines of light (L10, L11) on the two regions. <IMAGE>

Abstract: A fire protection nozzle of this invention has a base defining an orifice (50) and an inlet section (46) defining a conduit for flow of fire-retardant fluid, leading to an upstream end (52) of the orifice (50). A diffuser (42) is supported by arms (18, 20) extending from the base in a position downstream of the orifice (50) where fire-retardant fluid flowing from the inlet section (46) emerges from the orifice (50) in a coherent stream which impinges on the diffuser (42) to be deflected in a spray pattern.
