Title: Composite veneer
Inventor: PEARSON MARTIN THOMAS
IPC: D04H1/70
Filed: 1999-02-09
Abstract: The method and apparatus for forming composite wood products particularly composite veneer like products which may be intermediate products and laminated to form the final composite product. Strands are fed from a source of supply at a metered rate, entrained in an air stream and carried along a confined path between an entrainment zone and the source of supply. Strands are condensed onto a surface to form a veneer lay-up of at least one layer of strands on the forming surface and this veneer lay-up is carried from the path and deposited onto a collecting surface and later consolidated into a composite product. Entraining air and strands not forming veneer are separated in the supply station, the strands fall onto the supply of strands and energy is added to the separated entraining air and it is returned to the entraining zone.

Filed: 1999-03-09
Abstract: There is disclosed a method for forming a leader and a tail in a web of a papermaking machine that utilizes a water jet cutting apparatus having a nozzle.mounted for movement along a beam that extends transversally across the width of the web. The method includes the step of initially positioning the water jet nozzle at one end of the beam outside of the first edge and activating the nozzle to spray a liquid jet from the nozzle. Thereafter, a leader is formed in the web by moving the nozzle from the initial position to a predetermined position within the outside edge of the web at a chosen speed relative to the web travel speed. At this second predetermined position a slit is formed to form a tail. By choosing the relative speed a flatter edge or leader is formed to facilitate turn-up. The web is supported at the location of the cut into the edge of the web to reduce the risk of the web tearing. Also, the forming of this leader and tail in one operation reduces the apparatus hardware required to accomplish the formation of a tail and the cutting of a leader in two separate stations.

Abstract: A downhole tool and method are provided for collecting data from a subsurface formation during drilling operations. The tool includes a tubular mandrel adapted for axial connection in a drill string positioned in a wellbore penetrating the subsurface formation and a stabilizer element or sleeve positioned about the tubular mandrel for relative rotation between the stabilizer element and the tubular mandrel. A plurality of elongated ribs are connected to the stabilizer element. A means is connected to the stabilizer element for frictional engagement with a wall of the wellbore so as to prevent the stabilizer element from rotating relative to the wellbore wall. An actuator system is carried at least partially by the stabilizer element, and a probe is carried by one of the elongated ribs and adapted for movement by the actuator system between a retracted position within the one rib and an extended position engaging the wellbore wall such that the probe collects data from the formation. The method includes placing a non-rotating element of a tool positioned in a drill string in engagement with a wall of the wellbore such that the non-rotating element does not move relative to the wellbore wall. A probe carried by the non-rotating element is moved into sealed engagement with the wellbore wall to establish fluid communication between the formation and the non-rotating element, thereby enabling one or more properties of the formation fluid to be sensed.

Abstract: A method of actuating a trimming apparatus or directly a sorting apparatus for elongate workpieces and an installation for optimising the output of lumber such as in particular planed material using the method afford an increased degree of automation and thereby optimised and reproducible sorting results if each piece of the planed material (12) which is discharged rapidly from the planing machine (14) in the longitudinal direction firstly receives applied thereto only an identification code (18), preferably in the form of a bar code, with which is associated the result of pattern evaluation for surface defect location and classification. On the basis thereof an optimisation computer (20) determines optimum lopping and trimming parameters for the identification code (18). that is to say for the specific item of the planed material (12), in order to saw out of the planed material (12) a piece (12') of the maximum possible length , with the lowest possible of level of flaws, that is to say of optimum quality. Using the corresponding information for the control (25) of the lopping and trimming saw (13) the optimisation computer (20) actuates a clear-text producer (26) which. during the transverse transportation movement of the planed material (12) to the saw (13), such transportation movement being very slow in comparison with the longitudinal transportation movement. applies the relevant processing symbols to the planed material (12) which is identified by the identification code (18) thereof, which symbols are then fed by the clear-text reader (29) into the control (25) for the saw (13); unless transposition into visual recognisable symbols is entirely eliminated and the trimming control (25) is fed from the computer (20) directly in code-dependent manner.

Title: Linear sensor imaging method and apparatus
Inventor: VANDERKOOY GEOFFREY EDWARD
IPC: H04N1/047
Filed: 1998-07-15
Abstract: A first linear sensor array (42) produces, at a first time of occurence, a first image of a segment of an object (12) as the object moves across the sensor at a variable speed. The image and its time of occurrence are accumulated in a buffer. As the object continues to move across the sensor, a successive plurality of the segment images seen by the first sensor are accumulated in the buffer, together with their respective times of occurrence. A second linear sensor array (44) spaced a distance from the first array produces, at a second time of occurrence, a second image of another segment of the moving object. The second image is compared with the accumulated first images to determine which of the accumulated first images is most similar to the second image. The object's speed S can then be estimated as an appropriately weighted function of d/(t j-t m) (i.e. S ~ d/(t j-t m)], where t j is the time of occurrence of a selected one of the second images and t m is the time of occurrence of the first image most similar to the selected second image. By continually monitoring the object's speed in this fashion, one may select and transfer into an image buffer those image segments which together form the highest quality image of the object, independently of the object's speed of motion past the sensor and without the need for expensive, bulky stepper motors, mechanical motion encoders, or the like.
