Title: Method and apparatus for debugging and tuning a process control network having distributed control functions
Inventor: BURNS HARRY A
IPC: G05B19/02
Filed: 1997-09-26
Abstract: A system and method for debugging and tuning a process control network having distributed control functions implemented by a set of field devices communicatively linked over a bus include an operational scheduler that schedules the execution of each of a number of process control functions and communication functions performed by the field devices to define a process control scheme and an indicator that indicates one or more process control scheme locations at which the process control scheme is to be automatically or conditionally interrupted to thereby enable debugging and/or tuning of the process control network. A controller interrupts execution of the process control scheme at the indicated flow locations, communicates process data to a user to display the current or a past state of the process to a user and waits for user input before continuing with operation of the process control scheme. In a tuning mode, the controller delivers data pertaining to a process parameter to a tuning device or to a user which determines a new tuning parameter, such as a gain, to be used within the process control scheme based on the process parameter data.

Abstract: An apparatus and method for continuously forming composites comprising filler materials and thermoactive materials, particularly waste cellulosic materials and waste thermoplastics, are described. One embodiment of the apparatus includes either a batchwise or continuous mixer, such as a cyclone (10), for forming mixtures comprising filler and thermoactive material. The mixtures are conveyed to a continuous consolidation apparatus. Alternatively, the mixtures may be densified in a densifying apparatus before entering the consolidation apparatus. The consolidation apparatus includes a hot-gas distribution system having plural paired gas cells, such as rollers (50) or hoods, for applying hot air to the charge. A first cell of each pair applies gas to the mixture.  The second cell of each pair operates at a pressure less than that of the first cell, thereby creating a pressure differential across the charge.  Certain embodiments of the apparatus include at least one set of baffles (80) positioned adjacent a cell, at least one shroud (82) positioned about a cell, or at least one set of baffles (80) positioned adjacent a first cell and at least one shroud (82) positioned about a second cell. The baffles (80) and shrouds (82) are used to eliminate or substantially reduce the amount of gas that is vented to the surrounding atmosphere. The method comprises continuously consolidating the mixtures by applying a hot, dry noncondensable gas to the mixture. Besides the filler material and the thermoactive material the mixture may further include materials selected from the group consisting of biocides, fungicides, fire retardants, conductive materials, pigments, water retardants, wax-like materials, coupling agents, cross-linking agents, and combinations thereof.

Patent CA-2292441-A1 (CA)
Inventor: WHITEHEAD LORNE A
IPC: G02B26/02
Filed: 1998-05-08
Abstract: A variably reflective display device amenable to mutiple pixel display applications. Each pixel has at least one element (10) having a reflective state in which incident light undergoes total internal reflection, and having a non-reflective state in which total internal reflection is prevented. Such prevention is achieved by interfering with (scattering and/or absorbing) the evanescent wave adjacent the surface of the element. For example, a member (18) can be positioned adjacent the element and deformed between first and second positions. In the first position a gap (20) remains between the member and the elememt to allow the evanescent wave to behave normally. In the second position the member is in optical (but not atomic) contact with the element, such that the member interferes with the evanescent wave and thereby prevents total internal reflection. In one embodiment, each pixel is a grouping of retro-reflective elements (12A, 12B, 12C...) such as corner reflectors. An elastomeric material (18) is provided adjacent each grouping. If a gap (20) is left between the grouping and the elastomeric material, the grouping continues to exhibit total internal reflection. But, if the elastomeric material makes optical contact with the grouping, the evanescent wave is absorbed or scattered and hence total internal reflection is prevented, which in turn prevents reflection of incident light. Thus, the "pixel" formed by the corner reflector grouping is "off" if it makes optical contact with the elastomeric material, and "on" if a gap is left between the two.
