Title: Method and apparatus for separating and individually correcting repetitive and random velocity errors
Inventor: WAGNER STEVEN D
IPC: H04N5/956
Filed: 1987-06-09
Granted: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE        Velocity errors in a video signal are sampled at scan line rate and are averaged over a selected plurality of frames to enhance the repetitive velocity errors while cancelling the random velocity errors.  The resulting separated repetitive velocity errors then are subtracted from the initial combined velocity errors to provide sep-arated random velocity errors.  A repetitive error interlace technique is used to generate an improved repetitive error frequency control signal, while a second order correction technique provides a corresponding random error frequency control signal.  The two frequency control signals are combined and the combined signal is used to provide compensa-tion for the initial velocity errors.
Patent CA-1285724-C (CA)

Granted: 1991-07-09
Abstract: ABSTRACT OF THE INVENTION       A repaired elastomer article has a hollow in a non-reinforced portion of the article.  A cured preformed plug resides within the hollow and is adhered to the article through an amine curable polymer or prepolymer.  The amine polymer or prepolymer is curable at ambient temperature.  The preformed plug is made of a material which is compatible with the elastomer of the article.  The preformed plug material desirably has a lower modulus than the elastomer of the article and hence exhibits good physical properties such as enhanced longevity of the repair, good wear and the like. Since the amine curable polymer or prepolymer cures at ambient temperatures, the repair of the elastomer article can occur in situ.  The invention is especially useful in the repair of tires.

Abstract: ABSTRACT OF THE DISCLOSURE A hierarchical filing system provides a cataloging of data stored in various locations within a memory device. An upside-down tree type structure provides a downwardly expanding cataloging structure wherein directories provide for further branchings. A branching from a directory is terminated when a file is reached. Each directory is assigned a unique directory identifier value. Then, each file or directory is coupled with the directory identifier value of its parent to provide the interconnection necessary to form the cataloging structure. The complete cataloging structure is organized in the leaf nodes of a B-Tree structure and distributed in an ascending order of the key values to provide a systematic search for a given key. Each file is capable of storing a predetermined number of location description information when data is segmented into non-contiguous segments in memory. A file extents record is used to maintain record of the further segmentation. File location information is kept in the form of file extents descriptors in the leaf nodes of the separate File Extents B-Tree. This extents information is sorted in an ascending order based on a key comprised of a unique file number of a file relative starting block location of the file extent.

Abstract: ABSTRACT OF THE DISCLOSURE      The cloth-like, liquid impervious composite material is made by applying a nonwoven layer of loose, unadhered fibers to a liquid impervious film, and then point-bonding the nonwoven layer to the liquid impervious film to form discrete points of adhesion between the fibers and film. Because the fibers in the nonwoven layer are loose and unadhered when applied to the film, the resulting composite material has improved loft and softness.  Also, when the composite material is elasticized by an elastic material, it gathers into a more pleasing appearance.

Abstract: INVENTORS: REINHARD BLUHM, HERBERT HOLIK and PETER MIRSBERGER          INVENTION: METHOD FOR THE MECHANICAL-THERMAL DEWATERING OF A    FIBER STOCK WEB     ABSTRACT OF THE DISCLOSURE           During dewatering of a fibrous web, for instance a paper web, the latter in conjunction with a porous band, typically a felt, suitable for removal of the separated out water, is guided through an extended nip defining an extended pressing zone.  In the extended pressing zone the fibrous web, as viewed in a predeterminate travel direction thereof, is exposed in defined sections thereof to different high pressures and different high temperatures.  Upon arrival at the extended pressing zone the fibrous web is heated and in the first section of the extended pressing zone it is compressed to such an extent that there prevails a complete saturation of the capillaries of the fibrous web.  There is thus formed a hydraulic pressure which transfers water into the porous band.   In a second section of the extended pressing zone the web treatment pressure is reduced such that the hydraulic pressure tends to migrate towards null, but the capillaries in the fibrous web are still saturated.  In the extended pressing zone there is formed due to the reduced pressure steam which augments and increases the transfer of water into the porous band.  The steam flows from a heated surface of the apparatus  through the paper web while entraining free surface water out of the web capillaries into the porous band.  Prior to departure of the fibrous web out of the extended pressing zone the pressure is reduced such that when the fibrous web migrates to a subsequent ambient pressure region there does not arise any explosion-like expansion of the steam and damage to the fibrous web.

Abstract: CASTING MACHINE CONTROL            Abstract A dual drive sheet casting machine for casting metal sheet has a pair of water cooled rolls between which the metal is cast.  Each roll of the casting machine is driven by a separate motor, with one motor being a master and the other a slave driven at a controlled percentage of the speed or current of the master motor.  Differential current to the two motors indicates sticking or microsticking of metal to the rolls.  When the magnitude of the differential current exceeds  a high limit  indicating sticking,  the master roll is slowed to eliminate the sticking.  When the magnitude of differential current passed by a band pass filter between one half and ten Hertz exceeds a selected maximum indicating microsticking, the rotational speed of the master roll is decreased.  After making a change in roll speed, the control circuit is disabled for an interval to permit the casting machine to regain stability.

Abstract: Hot Melt Ink Supply system Abstract An object of the invention is to provide an improved hot melt ink supply system for ink jet apparatus which is especially adapted for use with pigmented hot melt inks.  In the representative hot melt ink supply system described in the specification, a first hot melt ink supply reservoir (27) maintains ink in molten condi-tion during operation of the system and a second res-ervoir (12) mounted with an ink jet head (11) on a movable carriage (10) communicates with the first reservoir (27) through a flexible supply line (36). The ink in the supply line (36) is normally kept in solid condition and, when a reduced level of ink is detected in the second reservoir (12), the supply line (36) is heated to melt the ink in the line and a pump (32) is actuated to transfer ink from the first reser-voir (27) to the second reservoir (12).  To permit use of pigmented inks, each of the reservoirs (27, 12) is heated to provide a thermal gradient therein so as to maintain convective circulation of the ink.  An ink circulation path is provided to cause convective cir-culation of pigmented ink in the ink jet head (11).

Abstract: APPARATUS AND METHOD FOR PREVENTING PAPER INTERFERENCE IN A RECORDING DEVICE            ABSTRACT OF THE DISCLOSURE A recording apparatus such as a facsimile machine records informa-tion on recording paper having a curved characteristic, such as a roll of recording paper. After recording, the recording paper is cut by a cutting device. A wedge-shaped plate, which functions as a jam prevention device, supports the rear end of stacked sheets of cut recording paper below the cutting position of the cutting device. Since the rear end of the lower side of the cut recording paper is supported by the jam prevention device along at least a portion of its curled length, even if the cut recording paper has a strong tendency to curl, the next sheet of recording paper slides on the pre-viously cut recording paper because it is securely supported by the jam pre-vention device. This significantly reduces the likelihood of interference between the previously cut recording paper and the next sheet of recording paper, even if the recording paper has a strong tendency to curl.
