Abstract: DOCUMENT DISPENSER WITH ESCROW SYSTEM     ABSTRACT OF THE DISCLOSURE         An apparatus for dispensing documents from a storage location to a discharge area includes structure for transporting the documents from the storage location along a transport path to an escrow or collection station.  The leading and trailing edges of the document are positioned in a holding position removed from the transport path at the collection station so that successive documents may be loaded into the collection station.  The apparatus includes a double detector for separating two documents removed at the same time from the storage location and for return-ing all but one of the simultaneously removed documents to the storage location.  When the proper number of documents have been collected in the collection station, they are moved along the transport path and deflected to the discharge area by a divert gate positioned in the path of the collection of documents.          However, the divert gate is positioned to deflect the documents to a divert bin where there has been an error in discharging docu-ments from the storage location to the collection station.  There-after, the dispensing cycle is repeated.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for making a sintered polycrystalline cubic boron nitride (CBN) compact by direct conversion of a pyrolytic, preferably substrate nucleated, boron nitride (PBN). Direct conversion takes place by subjecting the PBN to temperatures and pressures within the CBN stable region.  The crystallites of the compact produced by this process are preferentially oriented.  Also, such compacts have a high thermal conductivity between about 2 watts/cm°K and 9 watts/cm°K and thus are useful as a heat sink for electronic devices.  The size of the CBN crystallites of the compact may be between about 1 x 103.ANG.  to 1 x 105.ANG..

Abstract: Abstract of the Disclosure A composite video signal is separated into luminance and chrominance components by forming at least two estimates of the value of each component, based upon at least two sets of samples of the signal, and by selecting the best estimate based upon local picture characteristics.  In one embodiment, the first estimate is derived from samples associated with picture elements which lie along the same scan line as the element then being processed, while the second estimate is derived from samples associated with picture elements in different lines above and below the present line.  The best estimate selection is based on the relationship between each estimate and the component values of neighboring picture elements.  If desired, delayed separation can be used to determine the effect of each estimate on future separations, before a selection is made.
