摘要： A coalescing additive is used in the manufacturing process for gypsum wallboard. Such an additive increases the surface area and density of the slurry at the paper to core interface by coalescing the foam cells away from the paper core interface. This permits a stronger paper to core bond to form and increases the compressive strength of the gypsum wallboard as compared to standard wallboards made from slurries with reduced water levels.

摘要： The exhaust system for a marine engine provides a concentricity spacer located between an outer surface of a generally tubular member of a catalyst device and an inner surface of a generally tubular cavity formed within a catalyst housing structure. The concentricity spacer is shaped to allow fluid to pass through the spacer in a direction generally parallel to a central axis of the tubular member.

摘要： A computer apparatus, program and method function in a data processing system to replicate a cryptographic facility. The system includes a first cryptographic facility containing a portable part which personalizes the first cryptographic facility. The system also includes a second cryptographic facility which is linked to the first cryptographic facility by a public key cryptographic system. The portable part of the first cryptographic facility is encrypted and transferred to the second cryptographic facility, where it is decrypted and used to personalize the second cryptographic facility to enable replication of the first cryptographic facility. In one application, personalization of the second cryptographic facility can be in response to the detection of a failure in the first cryptographic facility. In another application, multiple cryptographic facilities can be brought on-line for parallel operation in the data processing system.

摘要： Circuitry within a device provides an output signal to an output pad of the device. One of a plurality of current levels is selected. When a first current level is selected, the circuitry generates only a first amount of current to maintain the output signal on the output pad. When a second current level is selected, the circuitry, in addition to the first amount of current, generates a second amount of current to maintain the output signal on the output pad. The first current level may be used in a test mode. In this way high current switching noise can be eliminated during testing. The second current level may then be used in a normal operating mode.

摘要： The patent describes a method and apparatus for securely distributing an initial Data Encryption Algorithm (DEA) key-encrypting key by encrypting a key record (consisting of the key-encrypting key and control information associated with that key-encrypting key) using a public key algorithm and a public key belonging to the intended recipient of the key record. The patent further describes a method and apparatus for securely recovering the distributed key-encrypting key by the recipient by decrypting the received key record using the same public key algorithm and private key associated with the public key and re-encrypting the key-encrypting key under a key formed by arithmetically combining the recipient's master key with a control vector contained in the control information of the received key record. Thus the type and usage attributes assigned by the originator of the key-encrypting key in the form of a control vector are cryptographically coupled to the key-encrypting key such that the recipient may only use the received key-encrypting key in a manner defined by the key originator.The patent further describes a method and apparatus to improve the integrity of the key distribution process by applying a digital signature to the key record and by including identifying information (i.e., an originator identifier) in the control information of the key record. The integrity of the distribution process is enhanced by verifying the digital signature and originator identifier at the recipient node.

摘要： The present invention employs a method of choosing between the output of two different character recognition systems to improve the rate at which characters are recognized, without significantly increasing the number of undetected substitution errors. If the first recognition system cannot recognize a character, a random probability generator is used to determine whether to use the output of the second recognition system, or alternatively to generate a reject character.

摘要： A compression tool comprises a tool head and a pair of dies mounted in the tool head for compressingly, surroundingly engaging a generally tubular workpiece. The dies define a minimum opening and a maximum opening therebetween for accommodating workpieces over a corresponding range of sizes. A fluid operated drive urges the dies inwardly to compress the workpiece and a fluid pressure control is provided for controllably varying the maximum pressure of the fluid supplied to the fluid operated drive in accordance with the size of a workpiece to be compressed.
