Abstract: ABSTRACT         A guide block (11) has a groove (16) with a flat floor cut into it, in which an endless belt (15) contain-ing perforations (17) travels.  A suction opening (18) opens into the floor of the groove (16), to which a vacuum is periodically applied by means of a valve (12).  The endless belt (15) travels over a stack (1) of sheets (2) by means of guide rollers (4,5) and a drive roller (3). The vacuum, when periodically applied by the valve (12), operates through the perforations (17) so that the top-most sheet (2) of the stack (1) is sucked against the endless belt (15) and carried away in the same direction (28).  One preferred form of the endless belt (15) is a toothed belt, with spaces between the teeth (21) that form vacuum chambers (22).  With this compact and there-fore easily positionable device, sheets (2) are sucked up from a stack (1) and transported away while maintain-ing their orientation, meaning that very high production rates are attained.

Abstract: EXTENDED ERROR CORRECTION FOR PACKAGE      ERROR CORRECTION CODES             ABSTRACT OF THE INVENTION          An extended error code particularly applicable to a code that can correct any number of errors in one sub-field but can only detect the existence of any number of errors in two sub-fields. If the initial pass of the data through the error correc-tion code indicates an uncorrected error, the data is  complemented and restored in the memory and then reread.  The retrieved data is recomplemented and  again  passed  through  the  error  correction code.   If an uncorrected error persists,  then a bit-by-bit comparision is performed between the originally read data  and the retrieved comple-mented  data  to  isolate  the hard  fails  in the memory.  The bits in the sub-field associated with the hard fail are then sequentially changed and then the changed data word is passed through the error  correction code.   A wrong combination is detected by the error correction code.  The se-quential changing continues until the bits in the sub-field associated with the hard fail match the originally stored data,  in which case the error correction code can correct the remaining errors in the remaining sub-fields.

Abstract: IMPROVED MICROWAVE ICE ACCRETION MEASURING INSTRUMENT                ABSTRACT     An ice measurement instrument includes a waveguide operating in a transmission mode passing energy from an input port to an output port.  The resonant frequency of the waveguide depends on the presence and/or thickness of ice at a measu-ring location.  The energy applied to the input port is swept in frequency from a first frequency to a second frequency at or above an ice-free resonant frequency of said waveguide, and back to said first frequency.  Energy re-ceived at the output port is peak detected to provide a detection signal with four recognizable transitions identi-fying a pair of peaks which correspond to the resonant frequency of the waveguide.  The time delay between these peaks can be used, in comparison with the time delay cor-responding to an ice-free condition, to determine ice thickness.

Abstract: MULTIPLE PATHS IN A SELF-ROUTING PACKET AND CIRCUIT SWITCHING NETWORK            Abstract A communication method and self-routing switching network interconnecting a plurality of interface controllers for communicating packets and circuit switched information via multiple paths within the self-routing switching network.  The latter comprises stages of switch nodes that are grouped into pairs.  The stages are interconnected by links and each pair of switch nodes shares the same set of input links from the preceding stage.  In response to receipt of address information from a destination interface controller transmitted via a link, a pair of nodes determines one of a multitude of paths through the switching network by one of the pair responding to the address information to communicate the address information to the next sequential stage after establishing a path through that particular switch node.  Once a path has been established through the switching network, an acknowledge signal is transmitted back through the network to the destination trunk controller indicating that the path has been established.  The path remains established until the end field of the packet is detected or the proper end information is transmitted after transmission of the circuit switched information.  The architecture of the switching network is such that no additional switch nodes are required beyond what would be required in a conventional self-routing network.

Abstract: ABSTRACT OF THE DISCLOSURE     PHOTON ASSISTED TUNNELING TESTING OF PASSIVATED INTEGRATED CIRCUITS          Covering metal test pads of a passivated integrated circuit process intermediate wafer or completed integrated circuit chip-to-test, with a thin conductive overlayer, and then accessing the test pads through the passivation layer and conductive overlayer, by a pulsed laser to provide voltage-modulated photon-assisted tunneling through the insu-lation layer, to the conductive overlayer as an electron current, and detecting the resulting electron current, provides a nondestructive test of integrated circuits.   The passivation,  normally present  to protect  the  integrated  circuit,  also  lowers  the  threshold  for photoelectron  emission.   The  conductive  overlayer  acts  as  a photoelectron  collector for the detector.  A chip-to-test which  is properly designed for photon assisted tunneling testing has test sites accessible to laser photons even though passivated.  Such a chip-to-test may be nondestructively tested in air at one or several stages of its processing, without the sacrifices of mechanical probing or of bringing test sites out to output pads.  The conductive overlayer may be removed after tests have been completed.  Integrated circuit process interme-diate chips may be specially designed for testability, with test sites grouped for easy access through windows left uncovered by subsequent layers.

Abstract: Abstract A retrieving mechanism for  subsurface releasing and retrieving of a downhole tool.  The apparatus includes an overshot defining a central opening therethrough and an annular cavity therein and a mandrel positionable in the overshot central opening.  A slotted C-ring with an inter-nally threaded surface is annularly positioned in the cavity in the overshot.  The mandrel includes an externally threaded portion.  Longitudinal insertion of the mandrel in the overshot results in ratcheting expansion and contraction of the ring for threaded engagement with the mandrel.  The threaded surfaces define a thread profile having a first surface, angled with respect to a central axis of the apparatus, which facilitates the longitudinal insertion of the mandrel in the ring, and a second surfacer extending normally to the apparatus central axis, which prevents longitudinal disengagement.  A seal is located above the ring for sealing engagement with a mandrel sealing surface.          In a lower portion of the overshot, a rotation plug extends radially inwardly, and on a lower portion of the mandrel a corresponding lug extends radially outwardly.  The lugs may be positioned adjacent one another for selectively pre-venting rotation of the overshot relative to the mandrel.

Abstract: Abstract A coating film comprises an amorphous carbon of a specified atomic ratio with respect to hydrogen and carbon and it is excellent in hardness, oxidation resistance, thermal resistance, electric resistance and thermal conductivity.  The coating film is produced by sputtering a graphite target electrode in an atmosphere of hydrogen, fluorine or a mixture of hydrogen and fluorides having a gas pressure of 6.665 to 666.5 Pa (0.05 to 5.0 Torr) while maintaining the relative current density for the graphite target electrode and a power source between 11.3 and 14.7 ma/cm2 thereby limiting the H/C ratio in terms of an atomic ratio between 0.5 and 0.9.  A sputtering apparatus used for producing such coating film includes a coating forming deposition substrate arranged at a position within a sputtering vacuum container which is not directly exposed to a plasma or a deposition substrate mounted on an electron drawing electrode within the container and a plasma adjusting electrode positioned in front of the substrate.
