Abstract: A file server includes a plurality of stream server computers linking data storage to a data network, and at least two controller servers for controlling the stream server computers. The controller servers are programmed so that at a given time one of the controller servers is active in controlling the stream server computers, and another of the controller servers is inactive. The inactive controller server is programmed to respond automatically to a failure of the active controller server by becoming active. For example, each of the controller servers has a respective flag for indicating whether or not the controller server is active. Each controller server is programmed so that, upon booting, it will read the flag of the other stream server, and if the flag of the other controller server indicates that the other controller server is active, then the controller server becomes inactive. Otherwise, the stream server assumes an active or inactive state based on a predetermined arbitration method.

Abstract: A process for controlling the etch of a silicon dioxide layer at a high etch rate and high selectivity with respect to silicon nitride, particularly in a multilayer structure, by maintaining various portions of the etch chamber at elevated temperatures.

Abstract: The present invention relates to a solid herbicidal composition comprising:a) oxyfluorfen herbicide dissolved in at leasti) a surfactant selected from alkoxylated acetylenic diol surfactants;ii) a surfactant selected from polyoxyalkylene alkyl ether surfactants, andiii) an alkoxylated organosilicone based surfactant,iv) a phosphate solvent of low water solubility, the ratio by weight of phosphate solvent to oxyfluorfen being lower than 3 to 1; andb) a water-soluble salt of N-phosphonomethylglycine, and optionallyc) an inorganic carrier,and to a process for the production thereof.

Abstract: A molded frame backboard assembly for supporting a rebound member between separately formed front and rear frames such that the peripheral edge of the rebound member is encapsulated within the frame. The rear frame preferably is formed as one piece of plastic material having sufficient strength and rigidity to support the rebound member and may include an internal reinforcing structure integrally molded therewith. The front frame preferably is molded from plastic and has a large central opening providing substantially unobstructed access to the rebound surface of the rebound member. The rear frame includes a recess that locates the rebound member in a predetermined position within the rear frame. The front and rear frame members include cooperating alignment structures that enable the front frame to be easily located on and attached to the rear frame after the rebound member has been positioned within the rear frame.

Abstract: Mutants of 2,5-diketo-D-gluconic acid reductase A an enzyme used to produce 2-keto-L-gluconic acid, a precursor of ascorbic acid (vitamin C), are prepared by site-directed mutagenesis. These mutants may exhibit one or more of the following characteristics: improved temperature stability, increased resistance to substrate inhibition, increased turnover of the substrate by the enzyme and increased affinity for the substrate.
