摘要:
Methods for optimally processing materials in a machine, such as a weaving machine, employing modular environmental control apparatus to control the conditions of gas flows sourced to or captured from various critical zones in materials processing machines. A plurality of processing performance parameters, part of which may respond differently to environmental conditions in one or more process zones, and thus may be in conflict with each other, are jointly controlled to yield maximum gross profit, to produce highest quality, to operate at highest throughput, etc., (but not necessarily simultaneously). One method includes the step of measuring at least one processing performance parameter, and at least partially controlling the processing performance parameter in accordance with a predetermined optimal control strategy by deliberately applying a gas flow conditioned by at least one controlling parameter, the gas flow being applied by a modular control unit. The disclosed embodiments are directed toward modular process zone environmental control in textile processing machines, both in yarn and fabric manufacturing processes, including weaving machines. However, Modular Process Zone Environmental Control (MPZEC) is applicable to materials processing in general.
摘要:
Gas flows, whose plurality of conditions are controlled by modular environmental control apparatus, are sourced to or captured from various critical zones in materials processing machines, or in related personnel zones. A plurality of processing performance parameters, part of which may respond differently to environmental conditions in one or more process zones, and thus may be in conflict with each other, are jointly optimized to yield maximum gross profit, to produce highest quality, to operate at highest throughput, etc, (but not necessarily simultaneously). The principal embodiments herein disclosed are directed toward modular process zone and personnel zone environmental control in textile processing machines, in fiber, yarn or fabric manufacturing processes, but the method is very basic and powerful, and those skilled in the art will recognize the applicability to materials processing in general.
摘要:
Method and apparatus for the collection of samples of staple fibers from a quantity (batch) of such fibers without material consideration of the “condition” of the fibers within the batch, (e.g., the relative humidity and/or temperature of the environment immediate the batch of fibers), and thereafter physically converting each sample of fibers to a tapered beard geometry, employing a rotary carrier. Each beard is grasped at one end thereof with the fibers thereof extending unsupported therefrom. The beard is conveyed to a location proximate the entrance to an air flow channel whereupon conditioned air flowing into the flow channel moves along, over and past the beard, causing the free ends of the fibers to enter the flow channel and become aligned generally along the length of the flow channel. Continued flow of conditioned air into and through the flow channel, hence in a direction generally parallel to the length of the fibers which make up the beard, ultra-rapidly conditions only the fibers of the beard. Air flow rates may reach hundreds or even thousands of ft/sec velocity within the flow channel and conditioning of the fibers may be accomplished within a matter of seconds. Withdrawal of the beard from the flow channel is sensed as a part of length testing of the fibers of the beard. Other test modules may be employed.
摘要:
An image-based method and corresponding apparatus for measuring, in scientifically basic terms, the complete fiber length distribution from a tapered beard. The method may be referred to as length by image analysis (Li). A calibration method is also disclosed.

An ultrasonic diagnostic imaging system is provided which aid in the diagnosis of patient conditions by providing access from the ultrasound system to a library of reference ultrasonic images. The image library is cataloged in accordance with an image characteristic such as the type of examination, the part of the body or the type of pathology shown in the image, and the images of the library are accessed in accordance with these characteristics. The image library may he remotely located and accessible by a number of ultrasound systems over a network, or it may be located on the ultrasound system itself such as on a system disk drive. In a preferred embodiment reference images are concurrently displayed with patient images to aid in discerning the patient's condition.

Machine for ultra-rapidly condition cotton fiber. In a processing embodiment for conditioning fiber being pneumatically transported by a gas flow, fibers are collected to form a thin mat. Aerosolized liquid is delivered to the thin mat, and then conditioned fiber form the thin mat is re-delivered into the gas flow.
摘要:
An apparatus and method for monitoring and processing a web of textile materials which includes a plurality of entities including fibers, neps, seed coat fragments and trash. The web is monitored, preferably by an imaging unit, to produce a monitor signal. A computer receives the monitor signal and locates the position of entities of interest and controls a web processor in accordance with the location of the entities. Preferably, the web processor includes ejectors for ejecting entities from the web under the control of the computer. In one embodiment, the web is formed by a sampler and forming apparatus which removes a sample of fibers from a supply and reconfigures it into a desired configuration, such as a web, for being monitored.
摘要:
Conditioned gas flows are applied at various critical locations in instruments and apparatus for testing and processing textile fibers, such as cotton. In the context of test instruments, a standard test zone environment (which becomes part of the test record) is effected by the introduction of controlled conditioned gas flows directly into a testing zone, including into testing instruments themselves. In the context of processing apparatus, direct control of processing performance parameters is effected by "controlling parameters", which are in turn effected by the application of conditioned gas flows. A plurality of "performance parameters", which may be in conflict with each other, may be controlled in accordance with a predetermined compromise control strategy, carried out by feedback or feedforward control systems implementing modern statistical control approaches.

Apparatus and methods for controlled application of aeromechanical and electrodynamic release and separation forces to foreign particulate matter in fiber materials are disclosed. A number of elements are employed in various combinations. One important element is a perforated, pinned cylinder which facilitates foreign particulate matter removal and microdust classification and use of conditioned and controlled airflow for optimum fiber processing and foreign matter removal. Another important element is a counterflow slot. Other important aspects are air blast cleaning of a tenuous mat held onto a perforated cylinder; unidirectional and pulsating airflows to cause repeated engagement of fibers with static cleaning pins and to release additional dust; application of electrostatic release forces to particles bound onto the fiber; and the processing of fiber in properly conditioned inlet air to the machine, as opposed to ambient air. These methods and apparatus enable the design of the precise and accurate measurement apparatus for foreign matter in fiber samples. They further provide effective cleaning, blending, and preprocessing of textile fibers for improved measurements of fiber properties. Still further, the invention may be applied to improved fiber cleaning equipment in gins or in textile mills. The invention ultimately permits a simplified spinning apparatus whose input is tufts and whose output is spun yarn.
