Abstract: A method and apparatus in a data processing system having a plurality of node controllers and a memory unit for each of the node controllers. Each one of the node controllers including at least one processor having a cache. Each memory unit including a plurality of entries each having an exclusive bit, an address tag, and an inclusion field. Each bit of the inclusion field representing one of the node controllers. The method and apparatus allow error recovery for errors occurring within the entries without using the ECC implementation. Specifically, two parity bits are used for detecting errors within an entry and logic for flushing any cache lines represented by the entry in error. The method and apparatus also includes means for detecting persistent errors and for indicating whether the error is generated by either hardware or software.

Abstract: Systems and methods for reducing the thermal stresses between an integrated circuit package and a printed circuit board, each having different thermal coefficients of expansion, to minimize thermal fatigue induced by power management cycling. The thermal impedance of the convection cooling system used with the integrated circuit package is switched with the state of the power management signal. A fan on the integrated circuit package heat sink is energized when the integrated circuit is operated in a high power mode and disabled when the integrated circuit is in a low power mode initiated by the power management system. The switching is directly responsive to the power management system and without regard to integrated circuit package temperature. The switching of the fan alters the thermal impedance to reduce the extremes of the temperature excursion and to materially reduce the rate of change of temperature experienced by the integrated circuit package.

Abstract: An emulsifier for emulsifying pesticide concentrates, the emulsifier consisting essentially of: (i) a sulfate as represented by general formula I: ##STR1## wherein R.sub.1 is an alkyl group having 8 or 9 carbon atoms, R.sub.2 is an alkyl radical having from 8 to 22 carbon atoms, x is a number from 4 to 10 and, y is a number from 2 to 20; and (ii) a nonionic surfactant selected from the group consisting of alkoxylated block copolymers of C.sub.8-12 alkylphenols, castor oil ethoxylates, mono- and di-esters of ethylene glycol, ethoxylated C.sub.8-22- alcohols, sorbitan esters, ethoxylated sorbitan esters, ethylene oxide-propylene oxide block copolymers, propoxylated-ethoxylated butanols, and mixtures thereof.

Abstract: A coating composition useful for plastic substrates is disclosed which comprises water having about 1-25% carboxy functional urethane polymer, about 1-25% carboxy functional acrylic copolymer, and about 1-10% aqueous alkali soluble resin dispersed therein. This composition is cross-linked by about 0.2-3% of a polyfunctional aziridine which may be added immediately before use, or prior thereto.
