Patent EP-0289084-A2 (EP)
Inventor: MORRISON BRUCE ROBERT
IPC: G01B11/00
Filed: 1988-04-21
Abstract: A high resolution CCD video camera (6) is positioned and aligned with respect to an illuminated article (7) so that a straight edge of the article, or a straight line junction between a bright zone and a dark zone of its surface, crosses the field of view of the camera in a direction substantially parallel to the rows of the camera's orthogonal array of rows and columns of light responsive elements,to divide that field of view into bright and dark zones. A frame store and digitiser (9) converts the individual signals generated by the elements into digital grey values. The grey values derived from the elements of each row are summed by a computer (10) to produce a linear array of summation values positionally related to the respective columns, and the computer then determines the position of the edge or junction to a sub-­column spacing accuracy by determining the mean value of two of the summation values selected respectively from a row receiving energy from the bright zone and one receiving energy from the dark zone and establishing a position in the array for the mean value, and thus for the feature, by interpolating the mean value between the two summation values immediately above and below it in magnitude.

Abstract: A thermal insulation liner is provided for a chromatograph oven. The liner is moulded as a single bucket-shaped component (1) from ceramic fibres, typically alumino-silicate, bound together with an inorganic binder. The heat capacity and thermal conductivity of this material are both very low. The inner layer of the oven can be rapidly cooled for fast throughput of analyses and there is low risk of hand burns when changing chromatograph columns. The inner surface is moulded as a smooth shape, assisting the flow of circulated air and thereby reducing hot spots. Thermal insulation for the injector and detector of the chromatograph are also moulded in together with entry holes and mounting points (3, 4, 5, 6) to enable an inexpensive, easily assembled oven and chromatograph to be produced.

Abstract: A method is described for the quantitative measurement of traces of gas, particularly CO₂ and CH₄ which constitute impurities in impure inert gases such as rare gases and nitrogen, by means of the use of a known analyzer for reducing gases, which uses a bed of mercuric oxide and makes the measurement by an optical method of the mercury vapours produced which are proportional into the concentration of the impurities to be detected. The method of the present invention subjects the impure inert gas to an electric discharge which may be at a high voltage, capable of ionizing the impurities before the impure inert gas is made to pass through the bed of mercuric oxide. The device according to the invention comprises, between a gas-chromatographic separation column and the analyzer, an electrode within a passage through which flows the gas to be analyzed and in which there is an ionizing discharge.

IPC: G01N3/32

Abstract: Electrical circuitry is useful for thermomechanical analysis apparatus. A sine-type wave force signal is generated by combining a triangular wave with an alternating wave equal in magnitude to about half of the square of the triangular wave. The triangular wave is generated with a control voltage proportional to the operating frequency. A response wave of the apparatus is amplified by an active filter circuit with corner frequencies approximately equal to each other and proportional to the operating frequency to process the wave independently of frequency. The force wave and response wave are converted to square waves which are combined to form pulsed time signals representing a phase difference for each half cycle. A pair of analog switches are receptive of the control voltage and responsive to the respective time signals to feed a switched output to an integrating capacitor such that successive voltage levels are effected in proportion to the time signals and the control voltage. Sample hold modules receptive of the voltage levels effect a steady voltage output representative of average phase shift independently of operating frequency and any time-­varying DC level in the response wave.

Abstract: Trenches (21) for separating semiconductor elements are laid out in a matrix fashion on a semiconductor substrate. A region surrounded with the trenchs (21) serves as an element forming region (22) where a semi­conductor element is to be formed. An interval between the adjacent trenches (21) is so selected that the ele­ment forming region (22) defines a minimum size of semi­conductor element. A semiconductor element requiring an area larger than the element forming region (22) is formed by using a plurality of element forming regions (22) with their trenches (21) partially removed. A capacitor resistors may be formed above the trench.

Abstract: For the large-screen projection of colour television pictures, picture reproducing arrangements comprising three separate picture tubes are in most cases used which are followed by projection optics. The colour television picture is created on a projection screen by superimposing the three monochrome television pictures. Instead of picture tubes, light valves can also be used, particularly liquid- crystal light valves with illumination optics. To increase the luminance resolution of a light valve projector, a geometric offset arrangement, preferably by half a picture element width in the horizontal and vertical picture direction of the light valves is provided. New picture scanning values are calculated by a signal processing circuit arranged in the light valve projector, in such a manner that the position of the picture scanning values and the position of the picture elements of the picture scanning values and the position of the picture elements of the light valves correspond to one another. The light valve projector is particularly suitable for reproducing high-resolution colour television pictures. <IMAGE>

The coupling comprises a male member (44) which is threadedly connected to the port and which includes tapered locking surfaces (64,62) on the male and female members, respectively, that are in tight frictional engagement when the male member is threaded into the female member (34). An O-ring (60) is positioned in a pocket (58) and disposed between the threads and the tapered locking surfaces to isolate the locking surfaces from hydraulic fluid, thereby ensuring a dry, frictional wedge lock. The O-ring is of a size that permits it to move axially in the pocket. In a modified embodiment of the coupling, there is provided an adjustable fitting which includes a lock nut (76) having a skirt portion (84) that is wedged into the tapered O-ring pocket (86).

Abstract: A plurality of letter output devices (workstations (102, 103, 104), printers (105)) are connected to a letter data control device (101) by a transmission path (106). The control device (101) stores letter data for transmission to the letter output devices (102, 103, 104, 105), and is able to convert that letter data to a desired layout (e.g. from a vector font to a dot font) and then transmits the converted letter data to one or more of the letter output devices (102, 103, 104, 105). The control device (101) is able to select part of its stored letter data for transmission so that only commonly used letter data need be transmitted during start up of the system. Since a large amount of letter data may be stored in the control device (101), and only part may be transmitted to the letter output devices (102, 103, 104, 105), those output devices (102, 103, 104, 105) can have a relatively small memory.

Abstract: A cavity or hollow-type package (8) for optically and non­optically active semiconductor devices is entirely made with moldable plastic material by utilizing a preformed box-like shell (4) of a rigid plastic material for enclosing the semiconductor die (1) and the electrical connection wires (2a,2b) before molding the whole in an epoxy resin. The protection shell is composed by two matching halves (4a,4b) and, in the case of optically active devices, the top half of the shell is provided with a window closed by a transparent pane which is sealed during the encapsulation. Preferably the two halves of the protection shell have two spaced lateral walls (7a,7a',7b,7b') forming two spaced sealing perimeters and an aux­iliary perimetral chamber (5) therebetween surrounding a cen­tral cavity (6) of the shell for accommodating any encapsu­lating resin which may eventually extrude through the out­er sealing perimeter during molding. The central cavity of the shell may be filled with a nonrigid silicone resin before molding for increasing further the protection. The entirely plastic hollow package may be formed through a normal plastic molding process.
