Patent EP-0309607-A1 (EP)
Inventor: BATEY ROBERT HENRY
IPC: G01F1/32
Filed: 1987-10-01
Abstract: A flow sensor, having an electrical frequency output proportional to flow, operates by bi-stable fluidic techniques acting upon an oscillator blade (24) being in proximity to a frequency transducer (28). The oscillator blade lies within a gap (22), the fluidic boundary layers (BL) discharging from which adhere to the oscillator blade, until a wedge shaped diverter (27) forces them away to join the main media stream. Both the momentary pressure drop across the diverter and the fluidic drag of the media leaving the diverter in one of its bi-stable positions, causes the blade to move to its alternate position, where the process is repeated, causing continuous oscillation. 
     The flow sensor may be fixed to an insertion rod into a velocity profile conditioning unit, whereby the mean velocity occurs within the inserted flow sensor, wherein fluidic processing provides accurate representation of flow in large pipes.

Abstract: The conveyor, in particular for root crop harvesters, consists of at least two continuous carrier belts (1) which run parallel and at a distance to one another, a number of chain bars (3) which are connected to the carrier belts (1) by their ends (5) with uniform spacing over the length of the said belts (1) and extend transversely with respect to the direction of the conveying movement (4), and of a belt lock (7, 107, 207) which in each case interconnects the ends of a carrier belt (1). The belt lock (7, 107, 207) is here designed as a separate hinge (7; 107; 207), whose connection plates (11, 12) bearing the link eyes (8, 9, 10) in each case engage under a free belt end (13, 14) and, together with a respective pressure piece (15, 16; 115, 116) arranged on the top of the belt end, clamp the belt ends (13, 14) between them. In this arrangement, the pressure piece (15, 16; 115, 116) can be moved against its belt end (13 and 14 respectively) by means of screws (17) which pass through holes in the belt end (13, 14) and transmits its compressive force to the belt end (13 and 14 respectively), via two parallel chain bars (3) assigned to said piece. <IMAGE>

Abstract: Circuit for the "unscrambling" of the multiplex signal (m) which is formed, in accordance with the formula m = ns1 + s2, from the two digital signals (s1, s2) which are redundant in such a manner that they represent a respective analog signal only by n amplitude levels instead of the maximum possible 2<p>, p being the respective number of digits of the digital signals and the following holding true for n: 2ld n less than or equal to 2p-1. Among other things, the circuit contains an iterative arrangement of cells (z...) which, in turn, consist of an adder (a...), a changeover switch (u...) and two delay sections (v...). The output of the final stage of the iterative arrangement supplies the digital signal (s2). The digital signal (s1) is formed from the carry signals of the adders (a...) by means of the inverters (i...) and the shift registers (sr...). <IMAGE>

Abstract: Bei einem bekannten Verfahren zur Herstellung eines vergrabenen Bereichs erhöhter Brechzahl in einem Glaskörper durch Ionenaustausch ist von dem Glaskörper eine Ätzmaske aus Titan zu entfernen, die vorher einer heißen Salzschmelze ausgesetzt war. Es ist problematisch ein Ätzmittel zu finden, das die Maske wegätzt, ohne daß die Glasoberfläche oder auch der Bereich erhöhter Brechzahl beschädigt wird. Nach dem neuen Verfahren kann das Titan problemlos und ohne Gefahr für die Glasoberfläche und den Bereich erhöhter Brechzahl entfernt werden. Das Titan wird mit einer EDTA-Ätzlösung abgeätzt und vor Durchführung des weiteren feldunterstützen Ionenaustauschs wird ein den Bereich erhöhter Brechzahl an der Oberfläche des Glaskörpers nicht beeinträchtigender geringfügiger Materialabtrag vorgenommen. Herstellung von vergrabenen Streifenwellenleitern und Streifenwellenleiterstrukturen in Glas.

Abstract: In the case of a plug for rock consolidation produced by injecting a curable plastic, reliable fixing of the plug (1) in a drilled hole is possible via a feed tube (35) owing to the fact that an expanding spring (8) connected to the elastic tube body (12) secures the tube body (12) in a drilled hole in both the direction of rotation (19) of a plug-side threaded clamping device (7) and the extraction direction (20) in such a way that the threaded clamping device (7) presses an expandable section (37) of the tube body (12) against the wall of a drilled hole. A non-reversing lock (6) in the area of the threaded clamping device (7) ensures that the feed tube (35) is unscrewed from the plug (1) by virtue of the fact that a locking body (26) secures the threaded tube by positive-locking engagement in a longitudinal groove (28), which threaded tube is turned in the release direction. <IMAGE>

Title: System for producing dithered images from continuous-tone image data.
Inventor: ULICHNEY ROBERT A
IPC: H04N1/40
Filed: 1988-03-09
Abstract: A digital image processing system for converting continuous tone pixel values representing an image into halftone or dithered pixel values, with the dithered pixel values representing each pixel having fewer bits than are used to represent each pixel in the continuous tone image. The continuous tone pixel for a line of pixels is loaded into an input buffer circuit having a plurality of storage locations, with each location storing the continuous-tone values for one pixel. Iteratively, the pixel value from each location is modified by a perturbed weighted error value, and then quantized to form the output halftone or dithered pixel value. An error value is then determined which is used in processing of subsequent continuous tone pixel values. The processing of the continuous tone pixel values procedes in a serpentine manner over the image, that is, processing of adjacent lines of the continuous tone pixel data proceeds in opposite directions.
