Abstract: ARTICLE TRANSLATION APPARATUS                      ABSTRACT An article translation apparatus is described for moving a series of substantially identical articles contiguously supplied to it, each of the articles having a rearwardly directed abutment face.  The apparatus comprises at least one endless conveyor loop having a series of article driving dogs equally spaced therearound, each dog having a downwardly extending driving spur adapted drivingly to engage the abutment face of an article and further including a slot at its leading end, each dog being rotatably mounted at its trailing end to the conveyor loop, the loop having equally spaced stop means extending into each slot to set upper and lower limits to the permitted rotation of each dog.  The conveyor loop is power driven and positioned above the articles with a lower flight substantially parallel with the direction of travel of the articles, the pitch of adjacent pairs of the dogs along the lower flight being slightly less than the pitch of the successive abutment faces such that as each lagging dog descends into a substantially horizontal position of driving engagement with the abutment face of one article, defined by said lower limit of rotation, the abutment face of the adjacent leading article is moved out of driving engagement with the adjacent leading dog.

Abstract: ABSTRACT OF THE DISCLOSURE      A downhole float valve is normally closed by a spring or other means of applying axial pressure until suf-ficient pressure of drilling fluid from the surface opens the valve.  The valve stem includes a dashpot type housing secured thereto and moving within a fluid filled cylinder.          When the valve opens, the movement is controlled by a one-way valve in the housing giving a relatively rapid opening.          When pressure of the drilling fluid from the surface is re-moved, the pressure on the underside of the valve typically assisted by the spring, closes the valve.  An adjustable bleed passage in the housing delays this closing for a pre-determined time thus allowing the pressure on the un-derside of the valve to balance with the pressure on the other side of the valve, but preventing an hydraulic lock or an hydraulic "stuck" situation from occurring.

Abstract: CONVERSION OF ASPHALTENE-CONTAINING CHARGE   STOCKS AND PRODUCT SEPARATION PROCESS                             ABSTRACT           A mixture of a hydrocarbon-selective solvent e.g. isobutane -- and deasphalted oil is separated in a two-stage hot-separator system at progressively higher temperatures and substantially the same pressure. Result-ing vaporous phases are subjected to a cold-flash separa-tion at a lower pressure and a considerably lower tempera-ture.  The initial hot separation, in the two-stage system, is effected at a temperature from 0.6°C. to 14°C. above the critical temperature of the solvent; the second is con-ducted at a temperature 17°C. to 72°C. above that in the initial hot-separation.  This technique is especially ad-vantageous when integrated into a catalytic slurry process for the conversion of metal- and asphaltene-containing hy-drocarbonaceous black oils.

Abstract: SLIP BAND ELECTROMECHANICAL CLUTCH ABSTRACT OF THE DISCLOSURE        An electromechanical clutch for vehicle engine cooling fans includes a driving member mounted for rotation by the vehicle engine and a driven member rotatably mounted on the driving member.  The driven member carries the engine cooling fan, and the driving member houses an electromagnetic coil which is energized to actuate the clutch.  The driving and driven members define a circumferentially extending gap therebetween.  A band is disposed within the gap, and includes an inner band member made of electromagnetic material and an outer band member comprising a resilient member with a frictional material attached to the outer circumference thereof.  The inner and outer band members are joined together so that the inner and outer band members may move radially relative to one another while actuation forces may be transmitted from the inner to the outer band to the connection therebetween.  When the clutch is engaged, the inner band member is drawn into driving engagement with the driving member by energization of the electromagnetic coil.  Accordingly, actuation forces are transmitted from the driving member to the driven member through the inner band member and the outer band member.  However, since only a frictional engagement exists between the outer band member and the driven member, the outer band member is permitted to slip relative to the driven member, thereby accommodating any torque overload condition.

Abstract: ABSTRACT         A method and apparatus for obtaining information on and identifying particles in a liquid suspension wherein the particles in suspension are moved in a stream through a plurality of sensing zones such that each particle passes through the sensing zones serially.  As each particle passes through a sensing zone a particular characteristic of the particle will be measured and its time relationship with the preceding and succeeding particle passing through that zone will also be preserved to form a pattern of time relationships.          The pattern of time relationships and the particle characteristics at a particular sensing zone will be correlated with the pattern of time relationships and particle characteristics at either a preceding or succeeding sensing zone in order to correlate all of the characteristics for the particle. The stream may also be passed to a substrate and the particles laid out on the substrate in a particular spatial pattern.  The spatial pattern is also correlated with the time relationships and particle characteristics at the last sensing zone preceding the substrate in order to correlate the particle on the substrate with all of its measured characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE A cache unit includes a cache store organized into a number of levels to provide a fast access to instructions and data words.  Directory circuits, associated with the cache store, contain address infor-mation identifying those instructions and data words stored in the cache store.  The cache unit has at least one instruction register for storing address and level signals fox specifying the location of the next instruction to be fetched and transferred to the processing unit.  Replacement circuits are included which, during normal operation, assign cache locations sequentially for replacing old information with new information.  The cache unit further includes detection apparatus for detecting a conflict condition resulting in an improper assignment.  The detection apparatus, upon detecting such a condition, advances the replace-ment circuits forward for assigning the next sequential group of locations or level inhibiting it from making its normal location assignment.  It also inhibits the directory circuits from writing the necessary informa-tion therein required for making the location assign-ment and prevents the information which produced the conflict from being written into cache store when re-ceived from memory.

Abstract: Abstract of the Disclosure A compact, light and highly efficient gas regenerator unit for a positive pressure closed circuit rebreathing apparatus having an improved carbon dioxide scrubber contained within an annular frame to the lower open portion of which a spring loaded flexible diaphragm is sealingly connected around its periphery and across the upper portion of which a cover plate is releasably attachable with the interior of the unit within the frame being divided by a transversely extending partition into a gas conditioning chamber,in which the CO2 of the wearer's expelled breath gases are removed by passing through chemicals compressively retained in the canister of a scrubber extending across the span of the gas conditioning chamber, and a variable volume gas chamber above diaphragm from which the reconditioned gases that have been enriched with a predetermined amount of oxygen are again inhaled.  A valving arrangement operated by movement of the spring loaded diaphragm will maintain a positive pressure within the system and add additional oxygen to the variable volume chamber when excess oxygen is being consumed by the wearer or vent excess gases from the chamber when oxygen consumption decreases.  An anti-anoxia valve prevents the wearer from breathing into the unit until oxygen is being released into the unit.  The design of the reconditioning gas chambers and passages including the CO2 scrubber, establishes a uniform flow of breathing gases through the scrubber and the unit with a minimum pressure drop.
