Title: System and method for controlling a materials handling system
Inventor: CROW HARRY K
IPC: F04B15/02
Filed: 1997-04-17
Granted: 2006-07-04
Abstract: A system and method is provided for controlling a materials handling system. The materials handling system preferably includes a feed system, a positive displacement pump and a disposal system. The feed system includes a material feeder, which in the preferred embodiment is a screw feeder driven by a drive, and a transition housing. The material feeder forces material through the transition housing to an inlet of the positive displacement pump. The control system includes a pressure sensor, located on the transition housing, connected to a computer. The computer is also connected to the drive of the screw feeder. During operation of the materials handling system, the pressure sensor senses a parameter indicative of material pressure within the transition housing and sends a signal to the computer representative of this parameter. The computer provides a control signal to the feed system to control operation of the materials handling system as a function of the sensed parameter.

Abstract: A general event composing and monitoring system that allows high-level events to be created from combinations of low-level events. An event specification tool allows for rapid development of a general event processor that creates high- level events from combinations of user actions. The event system, in combination with a reasoning system, is able to monitor and perform inference about several classes of events for a variety of purposes. The various classes of events include the current context, the state of key data structures in a program, general sequences of user inputs, including actions with a mouse-controlled cursor while interacting with a graphical user interface, words typed in free-text queries for assistance, visual information about users, such as gaze and gesture information, and speech information. Additionally, a method is provided for building an intelligent user interface system by constructing a reasoning model to compute the probability of alternative user's intentions, goals, or informational needs through analysis of information about a user's actions, program state, and words. The intelligent user interface system monitors user interaction with a software application and applies probabilistic reasoning to sense that the user may need assistance in using a particular feature or to accomplish a specific task. The intelligent user interface also accepts a free-text query from the user asking for help and combines the inference analysis of user actions and program state with an inference analysis of the free-text query. The inference system accesses a rich, updatable user profile system to continually check for competencies and changes assistance that is given based on user competence.

Abstract: Les éléments de répartition de fluides, selon la présente invention, comprennent, de préférence, trois composants de base: des fibres gonflantes, raidies chimiquement, tordues et bouclées, des fibres à surface active importante, ainsi que des fibres liantes thermoplastiques, l'utilisation, dans ces éléments, d'une fibre à surface active importante étant destinée à apporter, à l'élément de répartition de fluides, une pression (ou absorption) capillaire. Ces fibres à surface active importante sont généralement petites et peuvent être mises en forme, et elles fournissent au substrat une pression capillaire nettement supérieure à celle fournie par les seules fibres apportant du volume, raidies chimiquement, tordues et bouclées. Une fibre actuellement préférée pour l'utilisation de sa surface active est une fibre de pulpe de bois appartenant à la famille des eucalyptus. Les fibres d'eucalyptus apportent la pression capillaire généralement associée aux fines de cellulose, mais contrairement à ces dernières, elles présentent une longueur et un denier qui, tout en étant suffisamment importants, ne doivent pas remplir les vides constitués par les fibres raidies chimiquement, tordues et bouclées, et elles ne passent pas aisément à travers un écran en formation.

Title: Sprayer boom lock valve for sequencing unfolding steps
Inventor: CHAHLEY DENNIS W
IPC: F15B13/01
Filed: 1997-11-05
Granted: 2004-03-02
Abstract: The present invention relates to a sprayer boom lock valve for automating the setup sequence for sprayer operation from the transport position. The lock valve comprises a lever, spring biased toward a valve closing pin, and a cam secured on the secondary boom of the sprayer boom. When the secondary boom is rotated to release wheel locks in the setup sequence, the cam releases the lever which acts on the valve closing pin to close the valve and prevent any further rotation of the secondary boom. The valve is opened again by a linkage which is pulled tight when the sprayer wings are opened, retracting the lever and opening the valve. The hydraulic drive line is then reestablished to complete rotation of the secondary booms. The automated lock valve of the present invention prevents accidental under-rotation of the secondary booms which would be insufficient to release the wheel locks, and also prevents accidental over-rotation which would cause the secondary booms in the transport position to crash into each other damaging the sprayer.

Abstract: An easy-open beverage container and opening system therefor includes an opening provided in a barrier wall.      Covering the opening is a tamper-evident pull tab having a holding portion and a topmost free end portion. An adhesive adheres the holding portion to an outside surface of the barrier wall so that the hole is sealed.      A pair of slits is provided in the holding portion at opposite lateral edges of the holding portion adjacent the free end portion and the respective slits extend inwardly and downwardly away therefrom. The consumer grasps and pulls the non-adhered free end portion downwardly toward an opposite end of the holding portion to expose the opening. This causes a peeled part of the holding portion initially to be pulled from the barrier wall until the slits are reached; at which time the peeled part laterally separates from a remainder of the holding portion initially along the slits and then further along tear lines beginning at the lowermost ends of the slits to expose the opening. Preferably, the adhesive includes a first-strength adhesive and a second-strength adhesive having a strength greater than the first-strength adhesive so that when the peeled part tears downwardly along the tear lines, the tearing force required increases when the peeled part reaches the second-strength adhesive and the consumer can stop peeling at that point so that the peeled part remains attached to the remainder of the holding portion.
