Title: Method and apparatus for rolling rolled strips
Inventor: SEIDEL JURGEN
IPC: B21B27/06
Filed: 1994-03-28
Granted: 2004-11-23
Abstract: A method for rolling rolled strips 3, 4 in a hot strip rolling mill 6, comprises at least two roll stands 6, 7, with horizontally adjustable top and bottom work rolls 10, 11.      Each work roil is backed up directly or through an intermediate roll by a backup roll 9 or in a reversing stand where at least two passes are rolled, wherein the roll strip is subjected to a condition control for which profile the surface evenness-imparting correctively control elements act upon the rolled strip to meet requirements of profile accuracy and surface evenness of the rolled strips in spite of flexible rolling program if a target contour of the profile of the rolled strip 3, 4 is preset for achievement of which two groups of correction control elements act successively upon the rolled strip. The control elements 12, 13 of first group are brought to bear if a rolled strip thickness is above the critical thickness and influence largely the contour of the rolled strip in its central region referred to the strip center. The control elements 12, 13 of the second group are brought to bear in the strip edge region if rolled strip thicknesses below the critical thickness.

Title: Electronic control for turf maintenance vehicle
Inventor: LONN DANA R
IPC: G06F11/32
Filed: 1992-12-17
Granted: 1998-12-22
Abstract: The present invention provides for an automated clip control device for maintain ing a predetermined clip at varying ground speeds, heights of cut, and other changed conditions. The reel speed of t he mower (10) is controlled based upon a feed-back control loop, using as input the ground speed of the mower (10), the a ctual speed of the reel (48, 50, and 52), the number of blades on the reel, and height of cut, among other factors. A microprocessor (10 2) uses control process equations to determine the duration of an output pulse width modulated signal which is provided to a valve (702, 706) controlling hydraulic fluid flow to the reel motor (71-75). The target value of the reel speed is determined by reading the desired height or cut value and the number of blades per reel, and then going to a look-up table which contains optimized "lin ear distance traveled per time grass is cut" values. Once the appropriate look-up table target value is found, the target reel speed is determined by finding the product of the number or blades on the reel times the target clip times the ground speed times a const ant (to correct for units).

Title: In-line processing of a heated and reacting continuous sheet of material
Inventor: SEIDL PAUL G
IPC: F26B13/20
Filed: 1996-01-04
Granted: 2006-08-22
Abstract: A drying apparatus for a strip of material or web, including a conditioning zone immediately following but fully integrated with the dryer, to lower the bulk temperature of web. The web of material can be introduced to conditioned air which is substantially free of contaminants being evolved from the coating on the web. The temperature of the conditioned air is low enough to absorb heat from the web, effectively lowering the solvent evaporation rate, and can be controlled such that it is greater than the dew point of the contaminants being evolved from the web, thereby mitigating condensation that normally forms and visible vapors that form outside of the dryer enclosure.      Pressure control is provided in the conditioning zone so that solvent vapors will not escape and so that ambient make-up air can be regulated as required. Gas seal between the conditioning zone and the dryer prevents hot, solvent vapor laden air from the dryer from escaping into the conditioning zone.

Abstract: In the manufacture of a structural member comprising a thermoplastic composite core with an exterior reinforcing layer, the core member is initially extruded in the shape of a profile. The profile is then contacted with reinforcing fiber and resin to form the exterior reinforcing layer. The exterior thermosetting layer is cured to form a reinforcing layer. The structural member is preferably manufactured using a pultrusion method in which a tractor device is used to provide linear movement of the profile from the extrusion head to the exterior coating operation. The fiber-reinforced thermoset is coated on the entirety of the exterior of the profile or is applied only on a portion of the profile requiring reinforcement in a defined load-bearing direction. The preferred thermoplastic core comprises a polymer-fiber composite material. Such a structural member has significantly improved Young's modulus providing strength for applications such as telephone poles, electric poles, electric lighting poles, boat mast or keel applications, lumber replacements, structural members used in window and door manufacture, etc.

Abstract: A nonlinear editing system for audio, video and /or other source materials comprises a system to define at least one time line representing the edit, the time line being represented in the editing system as an operator graph. The operator graph includes operators, representing sources and time-based effects, and time varying connections therebetween. For each period of the defined time line wherein the connections do not change, a expression tree comprising a simplified representation of the operators and the connections required to render that portion of the time line is extracted.  Each expression tree can be examined to ensure that all of the required sources and/or connections are available to render that portion of the time line in real time and, if this is not the case, a determination can be made of which portions of the expression tree can be pre-rendered to an intermediate result, the intermediate result being substituted into expression tree to provide real time rendering.
