Abstract: A method for linking work requests in a work queue with entries on a queue of completed requests. For each work queue, a tracking list is created. Each tracking list is linked to one queue of completed requests. When a work request is added to a given work queue, an entry is added to the associated tracking list. The entry in the tracking list contains all of the information needed to uniquely associate a completion queue entry to the work request that caused the completion queue entry. When a completion queue entry is retrieved from the completion queue, the tracking list for the work queue is searched for an entry corresponding to the completion queue entry. The work request that caused the completion queue entry is then identified from the information in the tracking list entry.

Abstract: A method of reading configuration ROM in a serial bus device reads only portions of the ROM that are organized in a directory structure. Typically, the configuration ROM follows the IEEE 1212 and/or 1394 standards and uses an IEEE 1394 bus. Based on the information read from the configuration ROM, a connecting computer can determine the appropriate device driver to use for communications with the device.

Abstract: A system for permitting remote user access to regions of memory that have been exported for remote direct memory access purposes is provided. The system supports dynamically changing access privileges to remote users without requiring intervention from an operating system.

Abstract: After a reset on a bus, the topologies of nodes on the bus before and after the reset are accessed to identify nodes that are new to the bus. A host identifies itself in both the new topology data and the old topology data. Referring to the connectedness between ports of a node and other ports in the new topology, similarly connected nodes in the old topology are identified as matching. Identifying data present in the old data can be assigned to the corresponding node in the new data. Any nodes in the new tree lacking a matching node will require requests over the bus to obtain its identification data.

Abstract: Methods, systems, and software for installing and operating selected software applications on a client computer that is in communication with a server computer on a computer network is described. In one aspect, a method for installing and operating a selected software application on a client computer that is in communication with a server computer across a computer network. In one embodiment, browser software is provided on the client computer that includes a browser user interface and is effective to identify and download selected software applications from the server onto the client computer for execution thereby. A data transfer communication link is established between the client and server computers across the network, a desired software application is selected using the browser, and the desired software application is transmitted across the network from the server to the client.

Abstract: A one-pot process for the preparation of .alpha.-L-aspartyl-L-phenylalanine methyl ester hydrochloride is disclosed (.alpha.-APM(HCl)). .alpha.-APM(HCl) is an intermediate in the preparation of aspartame.

Abstract: A process for recovering acetic acid from a mother liquor containing acetic acid, formic acid, acetic anhydride and formic acetic anhydride comprising the steps of:(a) heating said mother liquor to a temperature greater than or equal to about 70.degree. C. for a time period ranging from about 1 hour to about 24 hours to convert all of said formic acetic anhydride to acetic acid and gaseous carbon monoxide and to fully deplete either said acetic anhydride or said formic acid, whichever is initially present in a stoichiometric lesser amount and thereby produce a mixture comprising acetic acid and either acetic anhydride or formic acid, whichever has been depleted; and(b) separating said acetic acid from the remainder of said mixture produced in step (a) is provided.

Abstract: A process for preparing ring-halogenated .alpha.-methylstyrenes from the corresponding .alpha.-halocumenes is disclosed. The dehydrohalogenation is accomplished using only water and optionally an organic solvent. The process eliminates the need for added base and a phase-transfer catalyst.

Abstract: An addition polymerizable antioxidant is prepared by reacting an isocyanatoalkyl ester of an addition polymerizable carboxylic acid (2-isocyanatoethyl methacrylate) with an antioxidant functionality bearing an active hydrogen moiety which is reactive with the isocyanate.

Abstract: Copolymers comprising 0.10 to 50 parts by weight of hindered phenol antioxidant monomer and at least 10 to 60 parts by weight of at least one unsaturated carboxylic acid monomer are prepared, preferably in emulsion polymerization systems.

Abstract: Polyoxazoline compounds are prepared by reacting a polymercaptan with a 2-alkenyloxazoline or a 2-alkenyloxazine. The compounds so prepared have at least two oxazoline or oxazine functionalities and can be employed in applications where a compound having an oxazoline or oxazine functionality has useful activity.

Abstract: An improved process for preparing derivatives of mercaptophenols containing nitrile, carbonyl, sulphone or ester groups characterized by reacting the components in a polar solvent with an amine catalyst. The catalyst can be removed from the product by co-distillation with the solvent to leave a relatively pure product free of contaminant without the need for further purification steps. The preferred amine catalysts are tertiary amines.

Abstract: An addition polymerizable UV stabilizer is prepared by reacting an isocyanatoalkyl ester of an addition polymerizable carboxylic acid (such as 2-isocyanatoethyl methacrylate) with an UV stabilization functionality bearing an active hydrogen moiety which is reactive with the isocyanate (such as 2-hydroxy-4-(2-hydroxyethoxy)benzophenone).

Abstract: Nitrogen oxides have been found to be effective to inhibit during distillation the vinyl polymerization of a 2-isocyanatoalkyl ester of an unsaturated carboxylic acid. For example, crude 2-isocyanatoethyl methacrylate was sparged with nitric oxide in nitrogen gas during distillation at 90.degree. C., so as to effect a concentration of nitric oxide in the gas phase of 376 parts per million by weight. Essentially pure 2-isocyanatoethyl methacrylate was recovered in 70 percent yield.

Abstract: A shift actuator for a multi-speed transmission includes a valve body and a spool movably positioned in a bore defined in the valve body. Fluid pressure acts on one end of the valve spool while a rotary cam is manually positionable to move the spool to various operating positions. Porting communicating with the valve bore is selectively blocked by the spool in its various positions.

Abstract: A food flagging device has a flag stem, a time identification means, a magnet support platform, and a magnetic means. The time identification means is either attached to, or is contained within, the flag stem. The magnet support platform is either attached to, or is contiguous with, the flag stem. The magnetic means is attached to the magnet support platform and has a magnetic field that is sufficiently strong to hold the food flagging device to a stainless steel surface. The food flagging device is heat-resistant and is capable of being sanitized.
