Abstract: FAULT TOLERANT LEAST RECENTLY USED ALGORITHM LOGIC    Abstract Binary logic is added to the binary logic normally utilized for the purpose of generating and decoding binary code combinations which reflect the order of use of a number of units, utilized in sequence, to thereby indicate the unit least recently used (LRU).  Disclosed is the utilization of six binary bits which are updated in accordance with a sequence of use of four units to thereby indicate the least recently used one of the four  units.  In accordance with known LRU techniques, there are 24 valid binary bit combinations that reflect the sequence of use of the four units.  The provision of 6 binary bits in the LRU code are capable of assuming 64 different permutations, therefore 40 combinations of binary bits are considered invalid when utilizing the LRU code.  The present invention utilizes certain of the invalid binary bit combinations to identify units that have been removed from further use because of a fault condition, and which code continues to identify the sequence of use of those units which have not been eliminated from further use.  The code chosen to identify a faulty unit and the sequence of use of the remaining units is fault tolerant in that additional errors in the coding mechanism can be tolerated, and ignored, while maintaining the ability to identify faulty units and sequence of use of the remaining units.

Abstract: METHOD OF PRODUCING LONG-CHAIN   ALPHA-HYDROXYALKANOIC ACIDS     ABSTRACT OF THE DISCLOSURE           Long-chain alpha-hydroxyalkanoic acids are prepared from alpha olefins having 10 to 18 carbon atoms by first adapting a microorganism of the Candida lipolytica species to assimilate the alpha olefins in such a way that the so-adapted microorganism pro-duces as the major metabolite of said assimilation alpha-hydroxyalkanoic acids having the same number of carbon atoms as the alpha olefins when the adapted microorganism is cultivated in an aqueous nutrient medium containing the alpha olefins.  The adaptation procedure comprises first cultivating the Candida lipolytica species in an aqueous nutrient medium containing kerosene boiling range hydrocarbons and then repetitively cultivating in a series of separate successive steps in an aqueous nutrient medium containing an alpha olefin the successive microorganism cultures obtained in the preceding cultivation steps beginning with the culture obtained using the kerosene hydrocarbons as the carbon source.

Abstract: ABSTRACT        A more compact high energy loss device is provided having a series of uniquely formed multiturn labyrinth assemblies which reduce the pressure of a fluid flowing therethrough.  The inlet of the labyrinth assemblies is formed according to a substan-tially circular configuration to have a predetermined inlet area while the outlet is formed according to a substantially scalloped configuration to provide an outlet area greater than the inlet area.  The scalloped configuration of the outlet yields an out-let area which is also greater than if the outlet were of circu-lar configuration.  The scalloped outlet configuration also makes the labyrinth assembly less susceptible to circumferential thermal stresses resulting from high temperature fluids passing through the device producing high temperature inlet conditions and low temperature outlet conditions.

Abstract: ARRANGING RANDOMLY POSITIONED ARTICLES INTO PRESELECTED POSITIONS            Abstract of the Disclosure Trailing wire ends of a cable supply on a pay-off reel initially are connected to respective matrix points of a controller in a preselected numerical order.  The cable then is fed from the reel, and a leading end portion is de-sheathed, using heat.  The desheathed portions of the cable wires then are pressed or "ironed" from a twisted-pair bundle configuration into an individual-wire common plane configura-tion.  As the desheathed portions of the wires next are fanned out of the common plane configuration in random order, they are sorted into two groups, depending on the side of connector plug on which they are to be located, in response to signals from the controller, which also identifies each wire and stores information as to its random nemerical posi-tion in its respective group.  The cable then is cut to length adjacent the supply reel and a new sequence of operations is initiated.  At the same time, a collating device, in response to signals from the controller, rearranges the wires into their proper wiring positions, after which the wires are secured to the connector plug.  A second connector plug can be attached on the opposite end of a cable in the same manner except that the first attached plug is plugged directly into the controller for the identification step. The production output of the system can be essentially doubler by feeding two different cables from separate supplies on alternate cycles of operation, and and processing both cables simultaneously.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE           Properties of a green sand for casting composed of siliceous sand, bentonite and water can be improved by utilizing surface activating characteristics of a waste liquor from the pulp manufacturing process.  When a pulp cooking waste liquor having a pH of 9 to 13 or a concentrate or powder thereof is incorporated into this green sand, the green strength, the flowability and the packing property are remarkably improved.          The used green sand mold has a good disintegrating property and the handling of the return sand is performed very easily, and the temperature control of the return sand can be remark-ably facilitated.  Further, when this green sand composition is used, occurrence of such defects as buckles, scabs, sand marks and cuts is effectively prevented.  When an aluminum ion or transition metal ion is incorporated together with the pulp cooking waste liquor, the foregoing effects are further enhanced.
