Abstract: ABSTRACT PROGRESSIVE SCAN VIDEO PROCESSOR PROVIDING VIDEO INTERPOLATION A processor, for providing a double line-rate video signal comprising alternating received lines and interpolated lines, comprises a triad of memories. As each incoming video signal is stored in one of the three memories, the remaining two are read at double the write clock rate. An output circuit interleaves a non-interpolated time compressed line of video obtained from one of the two memories being read with a time-compressed line of video obtained by interpolation from both of the two memories being read to provide a processed video output signal. The write-one read-two memory organization enables concurrent interpolation and speed-up of the video signal thereby minimizing potential clock timing problems inherent in progressive scan systems of the type where interpolation is provided separately either before or after video speed-up.

Abstract: The pneumatic tire is designed particularly to counteract unwedging of the tire. It is mountable on a rim having a protrusion (referred to as "hump") of ordinary shape. The bead has two bead rings, one of which is close to the bead tip while the other assures the blocking of the former in case of strong axial forces, which permits the bead tip to cooperate more effectively with the hump of the rim.

Abstract: La présente invention concerne un procédé de clarification à lit de boue pour liquide chargé de matières solides. Le liquide chargé à clarifier est introduit, après adjonction d'un adjuvant de floculation, au bas d'un lit de boue dans une chambre de clarification par une pluralité d'injecteurs répartie sur la surface de cette chambre. La répartition uniforme du débit total entre ces injecteurs est assurée par une perte de charge interne. Le liquide clarifié est évacué par un déversoir supérieur. Chaque injecteur forme des jets fortement divergents à partir de son axe vertical, de manière que le débit injecté se répartisse sur une zone d'expansion propre à cet injecteur et rejoignant les zones d'expansion des injecteurs voisins. De plus ces jets entretiennent des tourbillons qui empêchent la formation d'une couche de boue insuffisamment perméable. Application aux industries minérales et papetières.

Abstract: ABSTRACT OF THE DISCLOSURE     An aqueous solution containing 0.00005 to 0.2 mol/1 of copper ion and 0.0001 to 1.0 mol/1 of nitrate ion is effective to detect phosphorus segregates in a metallic material, particularly cast steel.  Segregated phosphorus can be detected by etching a surface of steel to be tested, attaching test paper onto the steel surface, applying the aqueous solution to the paper, maintaining the paper in contact with the steel surface for a sufficient time, and removing the paper from the steel surface.  A red print is obtained when the solution is pH 6 or higher.  A blue print is obtained by following the above steps, and further treating the paper with a color reagent containing molybdate ion, and then with a reducing agent.

Abstract: TUBULAR CONNECTION HAVING TWO THREAD SETS WITH MULTIPLE INTERENGAGING CHARACTERISTICS          Abstract of the Disclosure A tubular connection is disclosed having a small diameter thread set and a large diameter thread set, the small thread set having a lesser number of threads than the large set.  A primary torque shoulder is located between the threads sets and a secondary torque shoulder is located behind the large thread set.  In the preferred embodiment, the initial partial thread on the pin of both sets and the last partial thread of the small set on the box has a cylindrical root contour, whereas the remainder of the threads are tapered.  The longitudinal taper angle of the pin thread sets are dissimilar to the box thread sets, there being a maximum separation of the sets near the center of the connection.  Such dissimilar tapering tends to equalize the stress applied to the threads under tension loading.  At the center, a seal is provided with hooked threads on either side thereof.  The arrangement also provides a torque shoulder at either end of the large thread set.  The arrangement provides in a tapered con-nection having two thread sets of difference diameters, two torque shoulders and two metal-to-metal seal areas.

Abstract: ABSTRACT OF THE DISCLOSURE         A pretreatment system for wheat to be floured comprises a plurality of friction type wheat polishing machines disposed in series relation to form a continuous wheat polishing process line.  Each polishing machine includes a perforated tubular polishing member mounted on a frame and a frictionally polishing roll rotatably mounted on the frame.  The polishing roll is disposed with the polishing member and cooperates therewith to define therebetween a polishing chamber.          Upon the rotation of the polishing roll, it causes wheat grains supplied into the polishing chamber to be agitated and brought into frictional contact with each other to strip a pericarp from each wheat grain, to thereby polish the same.  A moisture supplying device supplies moisture to the polishing chamber of at least one of the polishing machines, to add the moisture to the wheat grains flowing within the polishing chamber, to thereby increase a frictional contact force between the wheat grains.  The friction between the wheat grains by the polishing roll causes each wheat grain to be moisturized and softened, to thereby facilitate the stripping of the pericarp from each wheat grain and the exposure of an endosperm part thereof.  A wheat flouring system comprises the above pretreatment system and a milling and screening system.  The milling and screening system comprises at least one milling machine for milling the wheat grains each having the endosperm part exposed to form a powder material, and at least one screening machine for screening the powder material to provide wheat flour having a desired particle size.

Abstract: ABSTRACT OF THE DISCLOSURE           A data transmission system having a number of control devices connected by at least one clock-control transmission loop operated directionally dependent insures that a data signal intended for a group of control devices in the system is actually received by all of the intended control devices.  The control device emitting the signal adds an entry preceding the data por-tion of the signal which identifies all receivers in the group and which also includes a block start identifier, and also adds a last entry to the data portion of the signal which is the address of the sending control device and a block end identifier.  Each con-trol device in the group, upon receiving the signal, copies the signal for possible processing, cancels the block end identifier in the last entry of the received signal, and adds a new last entry which is the address of the receiving control device, and acknowledgement of receipt of the signal, and a new block end identifier corresponding to the cancelled block end identifier.          The signal is then re-emitted to the loop for transmission to the next control device.  After the signal has been transmitted around the entire loop, it returns to the original sending control device which interprets the acknowledgement signals and corresponding addresses in the successively added last entries to determine whether all of the intended control devices in the group actually receive the signal.
