Abstract: For the purpose of establishing the clearing limit of a yarn clearing system, the yarn faults are determined, classified and counted. The parameters reference length and sensitivity are set in relation to the number of the corresponding clearer cuts on an orthogonal coordinate system. A clearing profile is thereby generated which represents the functional correlation between the quantity of all theoretically possible combinations of the yarn clearer setting parameters, and which reveals the number of clearer operations to be expected during clearing of the yarn for any combinations of the setting parameters.

Abstract: A system for controlling the consistency of a material (25) pumped from a reservoir (26), by introducing an alterant into the material, which system includes a diaphragm-type pump (20) for pumping the material from the reservoir, the pump being driven by a double-acting air cylinder motor (28) controlled by a pilot-­operated two-positioned, four-way air valve (36) having reducing valves (54, 56) connected at its air input ports (41, 42) to create pressure differentials between the input air and the operating air in the cylinder during steady state-operation of the pump. The motor (28) is mounted so as to be relatively movable substantially toward and away from the pump responsively to change in the pressure differntials in the cylinder due to changes in the consistency. A compression spring (62) forming part of the mounting, is disposed so that under steady state conditions of cnsistency of material being pumped, an equilibrium exists between the forces acting between the motor (28) and the pump (20) and the force acting on the motor (28) by the spring (62), the motor and pump not moving relatively to one another. A change in the consistency of the material will disturb that equilibrium, causing the motor to move relatively to the pump and such movement serves to operate a valve (68) that controls the introduction of alterant into the material.

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.
