Abstract: SELF-CHECKING, DUAL RAILED, LEADING EDGE SYNCHRONIZER                ABSTRACT         The present invention relates to a digital logic circuit and method for synchronizing the leading edges of a skewed true-complement signal pair.  The circuit of the present invention is comprised of two similar, interconnected circuit halves, each of which includes three D flip-flop stages.  The outputs from the second D flip-flop stages from the two circuit halves are applied to the two inputs of two identical logic gates, such that the signal pair is synchronously transmitted to a pair of output gates through a third D flip-flop stage in each circuit half.  The second D flip-flop stages also prevent metastable states from reaching the synchronizer output.  Metastable states may result if the input setup time is violated for the first D flip-flop stages.  The third D flip-flop stage in each circuit half also eliminates any signal irregu-larities generated in the logic circuitry from appearing on the synchronizer output lines.  The present invention is self-checking in that any single fault in the input signals or in the synchronizer circuit itself will result in the synchronizer output pair not having a true com-plement relationship.

Abstract: NICKEL-BASED ELECTRICAL CONTACT DEVICE            Abstract This invention relates to a device having an electrically conducting member having a contact surface consisting of a nickel-based contact material.  In accordance with the invention, the nickel-based material at least in a surface region (e.g. 23) comprises controlled amounts of hydrogen and has low electrical contact resistance even after prolonged exposure to an oxidizing ambient.  When used as a surface layer (e.g. 22) on an electrically conducting member (e.g. 21), such material is suitable as a contact material and represents an inexpensive alternative to gold.  And, when prepared in the form of microscopic flakes, such material is suitable for use in electrically conductive inks and adhesives. (FIG. 2)

Abstract: Open-End Ratchet-Like Wrench With Releasable Locking Head Abstract of the Disclosure A two way open-end wrench has a rotatable, captive, split socket which is selectively locked and unlocked to the wrench handle for torque transmittal through the meshing engagement of two opposed sets of teeth. One set is disposed around the periphery of the open-sided socket member and the other within the forward, concave end of a spring-loaded coupler disposed partly within and partly outside the wrench body. Engagement of the teeth is effected by the inward movement of the coupler when a user grips the wrench handle preparatory to turning it. Relaxation of the grip at the end of a stroke permits the handle to be returned to the starting position while the socket remains stationary. A projecting extension on the socket provides for manual rotation to the open position, permitting the tool to be withdrawn from a fastener on a tubing line, pipe or cable.

Abstract: lS513/703 PEK/KC     ABSTRACT OF THE DISCLOSURE     Encoding/decoding circuitry which processes data and both corrects single errors and detects multiple errors is disclosed.  The circuitry is both fail-safe and self-checking in that no internal device failure can alter data without producing improperly encoded outputs and all failures quickly reveal themselves through normal usage even if they do not actually cause any data to be modified.  The circuitry can be configured in two identical halves with each half operating on one half of the data so that the circuitry can be advantageously constructed with large scale integrated circuits.          Error-detecting information in the form of a syndrome produced by each circuit half is combined with similar syndrome information produced by the other circuit half.  The combined syndrome information is then decoded to generate error correction information which is used to modify the data bit outputs to correct detected errors.  A failure in either circuit half modifies the combined syndrome information in such a way that the modification can either be detected or else causes no erroneous data bit modification.

Abstract: "METHOD AND APPARATUS FOR REGENERATION   OF HYDROCARBON CONVERSION CATALYST              ABSTRACT        Regeneration of a spent hydrocarbon conversion catalyst is accomplished by means of a moving bed of catalyst, where catalyst is passed through several treatment zones, in a unique regeneration vessel.  The catalyst is first contacted with a hot oxygen-containing gas stream in a burning zone in order to remove coke.  The catalyst is then passed into a drying zone for removal of water formed in the combustion zone by passing a hot dry air stream through the catalyst.  This hot air stream is produced by exchange of heat with catalyst, thereby effecting cooling of the regenerated catalyst and by use of an air heating means located in the vessel.  After passing through the drying zone, the air stream provides oxygen for combustion in the combustion zone.

Abstract: An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by addition or subtraction of rows and lines of picture elements at positions which are the closest approximation to the newly scaled base, the picture elements corresponding to grey scale values. Reproducing a given image is scanned by photodetector elements (18). The added lines are duplicative of the next adjacent line. Subsequent lines of picture elements are shifted to close the gaps. A dot generator array (such as ink jet array, cathode ray tube, electrostatic or thermal recording system) responsive to the digital values of the picture elements generates the image in scanning fashion across a copy sheet at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued pictured data to a different location.

Abstract: The invention relates to a method of producing a plurality of multi-pane insulating glass assemblies (70) in which the assemblies (70) are formed into a self-supporting unit for further fabrication. Each assembly (70) is provided with at least one exteriorly accessible opening, and the assemblies (70), supporting one another in surface-to-surface contact, are moved along a conveyor as a unit into a vacuum chamber (10). Vacuum is drawn on the unit to evacuate each interpane space, following which a gas having coefficient of thermal conductivity lower than that of air is introduced into the chamber (10) to fill the interpane spaces of the glass assemblies (70). The assemblies (70) as a unit are then conveyed out of the vacuum chamber (10) and the exteriorly accessible openings are sealed. During the evacuation and refilling steps, the glass assemblies are maintained in a generally vertical orientation, and each glass assembly (70) is supported by a neighboring assembly against undue bowing of the glass panes due to pressure differentials between the interior of the vacuum chamber and the interpane spaces.
