Inventor: ANDERSON RAY
IPC: F16B15/06
Filed: 2000-05-09
Abstract: This invention relates to a means of insuring that nails are applied in the most efficient and effective way possible. This invention improves the method of permanently setting nails to ensure that the vertical drawing forces are opposed to the head of the nail.  The unique lateral extension of the head crown caused by the nail head crown flattening during the final placement into the substrate causing the outer edges of the head to be forced outward slightly under the top surface of the wood. The driving die head fits over the nail head crown, with three edges of the nail head fitting into the die, assures that the die and head will remain in that position through out the final setting of the nail. The final 45 degree twist used to set the nail fins and lateral extension of the head is a function of the driver die, and being rotated in a 45 degree spiral.

Title: Method for manufacturing forged wide sidewalls of a continuous casting mold
Inventor: FEHLEMANN GEREON
IPC: B22D11/057
Filed: 2000-06-15
Abstract: In a method for manufacturing a sidewall member of a continuous casting mold from a copper blank, wherein the sidewall member has an upper and a lower edge and a curved widened area beginning at the upper edge and tapering in a direction to the lower edge and to the sides of the sidewall member, the copper blank is hot-forged via several intermediate shapes to a rectangular plate with an initial wedge shape. The rectangular plate is then further formed by final hot-forging in a longitudinal direction of the rectangular plate with a straight saddle, having a width that is only a portion of a width of the rectangular plate measured relative to the longitudinal direction of the rectangular plate, and the curved widened area is preforged. Subsequently, the rectangular plate is quenched and work-hardened. The rectangular plate is then cold-hammered via a wedge-shaped bottom saddle for work-hardening a middle portion of the rectangular plate and for producing a final wedge shape of the rectangular plate. Finally, the entire curved widened area is work-hardened with a narrow saddle.

Patent CA-2321315-A1 (CA)
Inventor: VASANTHAN THAVA
IPC: C12P19/14
Filed: 2000-09-27
Abstract: A method is described for obtaining dextrin-enriched and beta-glucan-enriched fractions from barley flour. In particular, barley flour is mixed or ground in about 60%  ethanol at boiling temperature, then dextrinized by addition of thermostable alpha-amylase and reluxing at boiling temperature. The dextrinized mixture is filtered such that beta-glucan is retained on the filter and dextrin is in the filtrate. To increase the purity of the beta-glucan to at least >45% db and to increase the dextrin yield, the beta-glucan residue is resuspended in 60% ethanol and treated with alpha amylase and filtered as previously noted. After alcohol is evaporated from the combined filtrates, the dextrin is spray dried into a powder.
Patent CA-2321605-A1 (CA)
Inventor: MCFARLANE KEITH ROBERT
IPC: G06Q10/10
Filed: 2000-10-02
Abstract: The flow of work items (40) through a workflow process (50) is optimized by repeatedly reordering (FIG. 3) work items enqueued in inbox queues (21 ) of workflow process tasks (500) to maximize results according to a given business strategy expressed through target completion times and deviances therefrom. Each work item in an inbox queue has an associated in-queue rating (IQR 28) that represents the number of queue positions (23) that the work item can be retarded or needs to be advanced to meet its target task start time (TTST 31 ), target task completion time (TTCT 32), and/or target workflow completion time (TWCT 30). When a work item enters a queue, its IQR is computed (FIG. 2) as (a) either (i) the difference between TTST 31 and EWT of that work item, or (ii) the difference between TTCT 31 of this work item and the sum of the estimated wait time in the queue (EWT) of this item and the average handling time of a work item (AHT) by a task station (11) of this task, and (b) the resulting difference divided by the rate of advance of calls between queue positions (QAT 26) of that queue rounded down. An optimization function is then performed (404) on the queue to determine an order of the enqueued work items that optimizes a metric of those work items that may fail to meet their target times. For example, the order may be one that minimizes the number of the work items that will fail to meet their target completion times (those that have a negative IQR), or one that minimizes the amount of time by which the failing work items will exceed their target completion times. The work items in the queue are then reordered (406) accordingly. Whenever a work item changes its queue position, its IQR is recomputed (FIG. 4) as the sum of its present IQR and the number of positions that the work item has either advanced (a positive number) or been retarded (a negative number) in that queue.
