Title: Systems and methods for implementing a dynamic cache in a supervisory control system
Inventor: MCLAUGHLIN PAUL F
IPC: G05B15/02
Filed: 1998-08-17
Granted: 2007-05-15
Abstract: The present invention provides systems and methods for controlling processes of a process facility and, in particular, for distributing data among nodes of a real time process control system controlling such a fa-cility. An exemplary process control system includes a plurality of sensors, control-lable devices, and communication paths, and a computer system. The sensors and con-trollable devices are associated with various ones of the processes of the process facil-ity, and the communication paths couple the sensors and controllable devices to the com-puter system. The computer system oper-ates on data related to the process facility, and distributes the data among both client and process nodes. The client nodes de-sire data associated with processes of the facility and the process nodes control such process data. The computer system includes (i) a cache having a short access time for re-trieving records, and (ii) a supervisory controller, associated with the client and process nodes, that controls storage of the process data in the cache and selectively transfers the process data from the cache to the client nodes.

Title: Apparatus and method of generating stock turbulence in a fourdrinier forming section
Inventor: MCPHERSON DOUGLAS R
IPC: D21F1/20
Filed: 1999-06-17
Granted: 2007-09-11
Abstract: A method and apparatus generates turbulence to deflocculate relatively thick stock layers carried in an open surface forming section of a papermaking machine at operating speeds of up to 400m/min, for products having a basis weight of at least 160gsm. A dewatering box provides vacuum assisted drainage, having a set of dewatering elements, each set including a lead-in element, at least one intermediate element, and a trailing element. The path of the forming fabric is deflected downwardly as it passes over the intermediate elements, which are inclined at an angle between 0° and 10° from a plane defined by fabric supporting surfaces on the lead-in and riser elements. The resultant turbulence and agitation deflocculates the stock and reduces sheet sealing. The apparatus can be used in combination with other known formation and drainage devices, located either upstream or downstream, to augment their performance.

Abstract: A method of enhanced sterilization with improved material compatibility. The following enhancements have been made. First, repeated venting , evacuation, and plasma treatments can be performed in the pre-plasma stage. Second, a lower power level can be used in the post-plasma stage than in the pre-plasma stage. Third, after the post-plasma-stage, the chamber can be held at atmospheric pressure or sub-atmospheric pressure for a period of time after venting, before re-evacuating the chamber, rather than evacuating after the chamber is vented to atmospheric pressure or sub-atmospheric pressure. Any of the three enhancements may be used separately, and it is not necessary to practice all three enhancements to obtain at least some of the benefits of enhanced sterilization with improved material compatibility.

Title: Flow rate sensor, flow meter, and discharge rate control apparatus for liquid discharge machines
Inventor: YAMAGISHI KIYOSHI
IPC: G01F1/692
Filed: 1998-10-14
Granted: 2004-12-07
Abstract: A pipe line (4) for fluid to be detected is formed so that heat from a flow rate detector (12) in which a thin-film heating element and a thin-film temperature sensing element are laminated on a first surface of a substrate through an insulating layer is transferred to and absorbed by the fluid. In the flow rate detector (12), the temperature sensing which is affected by the heat absorption of the fluid due to the heating of the thin-film heating element is executed by the thin-film temperature sensing element, and the flow rate of the fluid in the pipe line (4) is detected on the basis of the temperature sensing result. A fin plate (14) extending into the pipe line (4) is joined to a second surface of the substrate of the flow rate detector (12) by a joint member (16), and the fin plate (14) extends so as to pass through the central portion on the circular section of the pipe line (4). The dimension of the fin plate (14) in the direction of the pipe line (4) is larger than the dimension Lz of the thickness.    Accordingly, even when the fluid is viscous fluid having relatively high viscosity, and further even when the flow rate is relatively small or under a broad environmental temperature condition, the flow rate of the fluid flowing in the pipe line (4) can be accurately measured.

Title: Improved aileron for fixed wing aircraft
Inventor: LAM LAWRENCE Y
IPC: B64C9/06
Filed: 1998-12-03
Granted: 2007-04-10
Abstract: An aircraft aileron system (10, 10) is comprised of two panels (12, 14, 28, 30, 62, 70) located at the rear portion of the wing (W24, 54), in a spanwise direction and aligned with the wing's trailing edge. The panels are independently hinged at their leading edges and rotate to make angular deflections with respect to the wing. The upper, aileron panel (12, 30, 62) is restricted to upward deflection only from its neutral position and in operation is deployed independently as an aileron. The lower, auxiliary flap panel (14 , 28, 70) is capable of both upward and downward deflections from its neutral position, and is deployed independently downward as an auxiliary flap. Both panels are deployed together upwardly only as an aileron. Alternatively, the auxiliary flap panel is capable of downwar d deployment only, to provide a simpler aileron system. For roll control of an aircraft during cruise, the aileron panel on one side only is deflected up while the aileron panel on the other side remains in its neutral position.

Abstract: An edible product in accordance with the present invention involves an edible inner component made from a first material and an edible outer cover component substantially completely encapsulating the edible inner component. In one form of the invention, the inner component is in the form of a hairball treatment for cats and the outer component is a dough-like material.  A system for producing the edible product includes a first material source for supplying a first edible material to form the inner component of the edible product, a second material source for supplying a second edible material to form the outer component of the edible product, and an extruder for continuously coextruding the first edible material and the edible second material to produce an elongated rope of edible product. A crimping apparatus receives the longitudinal rope extruded from the extruder for crimping the longitudinal rope to separate the longitudinal rope into individual edible products. A method for producing the edible product involves supplying the first and second edible materials to the extruder, and continuously coextruding the first and second materials as a longitudinal rope in which the first material is positioned within and surrounded by the second material. The longitudinal rope is cut at spaced apart locations as it is being extruded from the extruder to produce individual edible products each containing an inner component comprised of the first material and an outer cover component comprised of the second material that substantially completely surrounds the inner component, with the edible products being sealed at opposite ends.
