Date May 26, 1994A method for the manufacturing of an absorbent structure in an absorbent article, such as a sanitary napkin, tampon, panty protector, wound or sore dressing and like articles is produced by using absorbent material in roll form directly in the product without first defibrating the material and then forming a mat. The material possesses good dispersion properties and swelling properties, which are meaningful to the function of the product. A high surface dryness is obtained, among other things. In addition to cellulose fibers, the absorbent structure may also include superabsorbent material and/or binding fibers, among other ingredients. The pulp mat is very thin, therewith obviating the need to compress the mat further in the product. In the case of certain product applications, the material is softened mechanically prior to its use as an absorbent material.

Title: Parallel processor system
Inventor: DIEFFENDERFER JAMES WARREN
IPC: G06F7/57
Filed: 1991-11-13
Abstract: Multiprocessor parallel computing systems and a byte serial SIMD processor parallel architecture is used for parallel array processing with a simplified architecture adaptable to chip implementation in an air cooled environment. The array provided is an N dimensional array of byte wide processing units each coupled with an adequate segment of byte wide memory and control logic. A partitionable section of the array containing several processing units are contained on a silicon chip arranged with "Picket"s, an element of the processing array preferably consisting of combined processing element with a local memory for processing bit parallel bytes of information in a clock cycle. A Picket Processor system (or Subsystem) comprises an array of pickets, a communication network, an I/O system, and a SIMD controller consisting of a microprocessor, a canned routine processor, and a microcontroller that runs the array. The Picket Architecture for SIMD includes set associative processing, parallel numerically intensive processing, with physical array processing similar to image processing. a military picket line analogy fits quite well. Pickets, having a bit parallel processing element, with local memory coupled to the processing element for the parallel processing of information in an associative way where each picket is adapted to perform one element of the associative process. We have provided a way for horizontal association with each picket. The memory of the picket units is arranged in an array. The array of pickets thus arranged comprises a set associative memory. The set associative parallel processing system on a single chip permits a smaller set of `data' out of a larger set to be brought out of memory where an associative operation can be performed on it. This associative operation, typically an exact compare, is performed on the whole set of data in parallel, utilizing the Picket's memory and execution unit. <IMAGE>

Title: Verification method of fitting functionality
Inventor: KRUGER STEPHAN
IPC: G21C17/017
Filed: 1996-11-13
Abstract: The present invention relates to a method for testing if fittings are ready to operate. At least one measurement value for a fittings-specific variable is determined and compared with a previously established value. This measurement value is determined at the cold and non-pressurized state of the fitting and is compared with a value for the fittings-specific variable analytically determined from an operational model of the fitting. Upper and lower limit values associated with still admissible states of the fitting (design reserve) are established for this analytically determined value. It is shown that the fitting is ready to operate when the measurement value lies between the upper and lower limit values.
