Abstract: A method for coding/decoding and apparatus therefor. An encoder considers a frame representing a picture as comprised of areas. For each area, the encoder is capable of verifying and deciding: (1) which of the frame-based orthogonal transformation or field-based orthogonal transformation is more efficient for reducing spatial redundancy in a particular area of a picture, and (2) which of frame-based predictive coding or field-based predictive coding is more efficient for reducing temporal redundancy in that area. The most efficient orthogonal transformation technique is selected, and the most efficient predictive encoding technique is also selected to generate an encoded signal. The encoded signal is recorded on a recording medium, transmitted over a transmission channel, or broadcasted. A decoder at the other end decodes the encoded signal. Pictures containing a small amount of movement, pictures containing a great amount of movement, or mixed pictures containing a rapidly moving body on a still background may be reproduced with high efficiency.

Abstract: A process for removing acetylene from a hydrocarbon stream comprises exposing the stream to a hydrogenation catalyst in the presence of an acetylene converter modifier which substantially remains on the catalyst and does not unsubstantially migrate into the stream. Exposure is under conditions which are effective to support acetylene hydrogenation with enhanced selectivity. The moderator, which may be arsine or phosphine, is used at a low concentration level and serves to prevent temperature runaway during the exothermic acetylene hydrogenation reaction. By controlling the presence of moderator levels to such a relatively low level, temperature runaway during the highly exothermic acetylene hydrogenation reaction is prevented while maintaining acceptable catalyst activity levels for purposes of the acetylene hydrogenation reaction.

Title: Detection of nucleic acid amplification
Inventor: NADEAU JAMES G
IPC: C12Q1/6844
Filed: 1995-03-28
Granted: 1998-06-30
Abstract: Methods for detecting, immobilizing or localizing primer extension products of aStrand Displacement Amplification reaction which are coupled to, and an indication of, amplification of the target sequence. The primer extension products are secondary, target-specific DNA products generated concurrently with SDA of the target sequence and can therefore be used to detect and/or measure target sequence amplification in real-time. In general, the secondary amplification products are not amplifiable and remain inert in the SDA reaction after they are formed without interfering with amplification of the target sequence. The secondary amplification products may be designed or modified to contain special features to facilitate their detection, immobilization or localization.

Title: Carcass cleaning system
Inventor: KARUBIAN RALPH K
IPC: B05B14/00
Filed: 1995-04-27
Granted: 2004-12-14
Abstract: As a carcass moves down the conveyor in a meat processing plant, it may carry contaminants from an earlier processing step.      The contaminants are removed by simultaneous vacuum and spraying on of a cleaning liquid. The liquid loosens the contamination, and the vacuum removes the contamination and liquid. A hand-held carcass cleaning system head is connected by flexible lines to the fixed part of the system and is manually moved over the surface to be cleaned. Alternatively, the surface is sterilized, and the contaminants are removed by simultaneous delivery of steam to the surface and vacuuming away of the steam. A sterilizing hot water spray is controlled by a valve so that the operator may deliver it to particular spots that need more cleaning.

Abstract: A method of identifying untestable faults in a logic circuit.  A lead in the circuit is selected and the circuit is analyzed to determine which faults would be untestable if the selected circuit lead were unable to assume a logic 0 and which faults would be untestable if the selected circuit lead were unable to assume a logic 1.  Faults that would be untestable in both (hypothetical) cases are identified as untestable faults.  Faults which would be untestable if the selected lead were unable to assume a given value may be determined based on an implication procedure.  The implication procedure comprises the forward propagation of uncontrollability indicators and the backward propagation of unobservability indicators.  An uncontrollability indicator for the given value is assigned to the selected circuit lead and propagated forward through the circuit according to a set of well-defined propagation rules.  In addition, unobservability indicators are generated in the circuit based on the propagation of uncontrollability indicators.  These unobservabilityindicators are then propagated backward through the circuit.  The (hypothetically) untestable faults are then determined based on the resultant indicators and their corresponding circuit leads.  Untestable faults may be identified in a sequential circuit by generating an equivalent combinational iterative array circuit model for a fixed number of time frames. Faults that would be untestable in both (hypothetical) cases and which are located in the last (i.e., latest-in-time) time frame are identified as untestable faults.
