Abstract: ABSTRACT OF THE DISCLOSURE            In the manufacture of frames, particularly wooden frames, the glued faces have to be pressed together along the bevelled cuts.  For this purpose a clamping frame is disclosed which has a closed rectangular clamping frame comprising a first frame portion with two limbs at right-angles to each other and a second frame portion with two limbs at right-angles to each other.  The second frame portion is displaceable relatively to the first frame portion and the limbs of the second frame portion project outwardly beyond the limbs of the first frame portion.  On the outside of the limbs of the first frame portion and parallel thereto are pull rods which intersect at the corner of the first frame portion and engage the projecting limb sections of the second frame portion.  Clamps can be applied to the sections of the limbs of the second frame portion that project beyond the limbs of the first frame portion as well as to the pull rods, which clamps are supported on the outside of the limbs of the first frame portion and with which the second frame portion can be tightened to the first frame portion.  By means of such a clamping frame, frames of different size can be clamped simply and conveniently.

Abstract: ROUND OFF CORRECTION LOGIC FOR MODIFIED BOOTH'S ALGORITHM MULTIPLIER            Abstract of the Disclosure A round off correction logic circuit is disclosed for inclusion within a floating point arithmetic binary digital multiplier implementing a modified Booth's algorithm for generating a final product of binary digits.          The round off logic circuitry is connected in the mul-tiplier for rounding its final product off to a predeter-mined binary digit without requiring the multiplier to generate any of the less significant binary digits to the right of the predetermined binary digit.  Multiplier circuitry otherwise required to generate an unrounded final product prior to round off is eliminated without loss of accuracy in round off.

Abstract: ABSTRACT OF THE DISCLOSURE       A cold-water dispersible, modified starch characterized by form-ing a gel having a Bloom strength of at least 45 grams is prepared by converting a tapioca starch to a water fluidity of about 10 to 63, preferably 20 to 40; reacting the starch with a crosslinking agent to within defined Brabender viscosity limits sufficient to provide the modified starch with gelling properties; and drum-drying the converted, crosslinked starch to obtain the modified starch product.  The gelling instant starch thus prepared is particularly useful in food systems of the type which gel upon standing, such as pie fillings, jellies, and puddings.

Abstract: INTERNAL AIR RELEASE CONTROL APPARATUS        AIR GUN     ABSTRACT OF THE DISCLOSURE       Disclosed is a seismic source device, known in the industry as an air gun, having shuttle control for allowing a predetermined discharge of compressed air into water for pur-poses of seismic exploration.  The shuttle is controlled by valve means for closing the exhaust ports before all of the compressed air in the firing chamber of the air gun is ex-hausted.   By preventing further discharge of air, with little or no loss in acoustic output, secondary pulses are greatly reduced, thereby enhancing the operation of the entire system.  Further by preventing all the air in the firing chamber from being discharged, the system becomes more efficient and more cost effective.

Abstract: ABSTRACT OF THE DISCLOSURE        Particulate or fibrous material, after treatment with gaseous reagents in a vessel under pressure in a continuous process, is discharged from the pressure vessel by entering a discharge conduit in pressure communication with the pressure vessel, and is conveyed through the discharge conduit by means of a feed conveyor  located therein.  The feed conveyor compacts the material to form a dense, substantially gas impervious plug thereof in the discharge conduit against the outlet end thereof.          The outlet end of the discharge conduit comprises an exit passage of small cross-sectional area so as to cause compaction of the material therein by means of the conveyor.  A valve means is provided, movable rapidly between a fully open position and a fully closed position to permit passage of the cooked material therethrough, from the dense, compact plug formed in the outlet end of the discharge conduit.  Operating means is provided to move the valve rapidly between its fully open and fully closed positions, at predetermined intervals.  In this means, the cooked material can be discharged intermittently at frequent intervals from a pressure vessel, allowing the pressure cooking process to be conducted continuously.  The dense compact plug prevents reagent losses and pressure losses on discharge of the material.  The process is particularly well adapted to the steam cooking of wood chips to produce fibrous cellulosic product.

Abstract: ABSTRACT OF THE INVENTION      An apparatus that controls the swinging of a frame (50) and the rotation of a turret (52) in an automatic web rewinding machine. The frame (50) is pivotally mounted in the machine and a turret (52) including a plurality of rotatable mandrel assemblies (56) is mounted for rotation within the frame (50). The control apparatus includes an indexing device (66) having an output shaft (70) that undergoes intermittent rotation in response to continuous rotation of an input shaft (68). One drive means (80), coupled and responsive to the output shaft (70) of the indexing device (66) provides intermittent rotation of the turret (52). A second drive means (78) is provided to control the rotation of the cam (60) in order to minimize the overlap of the rotation of the cam (60) with the dwell time of the turret (52). The optimum condition occurs when the cam (60) rotates only when the turret (52) is indexing and when the cam (60) does not rotate at all while the turret (52) is dwelling. This optimum condition is achieved by having the second drive means (78) also coupled and responsive to the output shaft (70) of the indexing device (66) for providing the intermittent rotation of cam (60) in synchronism with the rotation of the turret (52).
