Abstract: ABSTRACT OF THE DISCLOSURE           Programmable video inspection apparatus. The invention includes a camera for viewing an object of interest, the camera presenting a video signal to both a monitor for operator viewing and a digitizer. The digitizer generates an array of digitized pixels from the video signal and stores the same in a memory. A processing unit compares specific groupings of pix-els known as windows against predetermined values to determine the acceptability of the object.  The pre-selected values may he generated by the operator by viewing an object of known quality on the monitor and by selecting the windows of interest for such objects by means of a control panel.  The operator can define the windows of interest as to position and size, as well as with respect to the test to be conducted upon such window, the threshold levels associated with the window, and the minimum number of pixels within the window which must satisfy the test.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus are provided for projecting mortar or concrete. The apparatus includes a first material supply   pipe for conveying a first material under pressure, the first material comprising one of the ingredients of the mortar or concrete.  A hopper is provided which is adapted to be charged with a second material, the second material comprising the other ingredient of the mortar or concrete.  A second material supply pipe is connected to the hopper.  A rotary screw is disposed in the second material supply pipe for mechanically conveying the second material supplied from the hopper.  A rotary disc is provided for admixing the first material conveyed through the first material supply pipe, and the second material conveyed through the second material supply pipe, to project a resulting mixture.  In this invention, the first material supply pipe, the second material supply pipe and the rotary disc are all arranged coaxially, and the first material supply pipe and second material supply pipe are arranged concentrically with one another. According to this invention, since green concrete is projected by centrifugal force instead of by pressurized air, quantities of dust and rebound formed at the projected surface are small, so that the period of projection of the con-crete or mortar can be increased.

Abstract: METHOD AND APPARATUS FOR COMPRESSING DIGITAL DATA    USING NON-ADAPTIVE PREDICTIVE TECHNIQUES            Abstract of the Disclosure A method and apparatus for compressing digital data derived from an image using non-adaptive predictive techniques.  A prediction table, which is pre-generated based on a number of sample images, generates a predicted pixel and source state for each pixel of the original image, as the original image is scanned.  The predicted pixel is the expected value of the pixel when considering the values of a group of adjoining pixels, while the source state is indicative of the probability that the predicted pixel is in error.  Prediction error pixels are then generated and grouped according to their respec-tive source states to form a plurality of run length symbols with each symbol comprising a white portion and a black portion, which symbols are stored sequentially in order of formation in a memory device according to their respective source states. The symbols are used to provide address data for memory devices which generate variable length code words that are transmitted to a receiving station and decoded using the reverse of the aforementioned process to form a facsimile image.

Abstract: METHOD OF INDUCING FLOW OR DENSIFICATION OF PHOSPHOSILICATE GLASS FOR INTEGRATED CIRCUITS                   Reda Razouk ABSTRACT      Phosphorus-doped silicon oxide glass is flowed on an integrated circuit by raising the pressure in which that integrated circuit is placed above atmospheric for a selected period of time and heating said phosphosilicate glass to a selected temperature sufficient to cause said glass to flow at said pressure.  The atmosphere in which the device is placed includes moisture to enhance the flow of the glass at temperatures substantially beneath those at which dopants in the underlying integrated circuit move.  The result is that the electrical characteristics of the integrated circuit are not substantially altered during glass flow.

A sensor element (32) is adapted to be placed alongside the sheet path, and a base member (34) is adapted to be positioned on one side of the sheet and in sliding contact with one surface thereof.  The sensor element is enabled to produce a sheet property sensing interaction with the sheet in a limited region of the sheet path, the interaction region being movable to any one of a plurality of sensing locations spaced across the width of the sheet.  The base member has a pair of groove portions (44, 46) forming gas conducting channels with open sides exposed to the sheet surface in contact with the base member.  Each of the groove portions has a part (40, 40A) extending upstream of the interaction region.          The groove portions diverge from each other as they extend in a downstream (20) direction.  A source of subambient gas pressure communicates with the groove portions for reducing the gas pressure therein so that the contacting surface of the sheet is at least nominally depressed into the groove portions to such an extent that the divergence of the grooves and the longitudinal movement of the sheet exert thereon a transverse tension.  This tension is sufficient to substantially smooth out longitudinally extending sheet wrinkles.  Typically a plurality of gas removal devices are provided for minimizing the introduction of gas between the base member and the sheet.
