Patent CA-2246892-A1 (CA)
Inventor: TIAN LINING
IPC: C12N5/10
Filed: 1998-09-09
Abstract: T-DNA tagging with a promoterless .beta.-glucuronidase (GUS) gene generated transgenic Nicotiana tabacum plants that expressed GUS activity either only in developing seed coats, or constitutively. Cloning and deletion analysis of the GUS fusion revealed that the promoter responsible for seed coat specificity was located in the plant DNA proximal to the GUS gene. Analysis of the region demonstrated that the seed coat-specificity of GUS expression in this transgenic plant resulted from T-DNA insertion next to a cryptic promoter. This promoter is useful in controlling the expression of genes to the developing seed coat in plant seeds. Similarly, cloning and characterization of the cryptic constitutive promoter revealed the occurrence of several cryptic regulatory regions. These regions include promoter, negative regulatory elements, transcriptional enhancers, core promoter regions, and translational enhancers and other regulatory elements.

Title: Screw for use as a fastener in fibrous material such as wood
Inventor: WALTHER THORSTEN
IPC: F16B33/02
Filed: 1999-03-29
Abstract: The thread (15) of a wood or the like screw has pairs of V-shaped recesses (22, 23) in the edge of a selected intermediate length of the thread (17). Each pair defines a W-shaped cutout (19, 20, 11). The cutouts (19-21) extend into only a part of radial width of the thread (15). There are only about three cutouts (19-21) at each convolute (17) of the limited length. The lengths of the thread (16) at the tip and at the head (13) of the screw are smooth.  Each cutout defines a cutting tooth (24) which facilitates the driving of the screw into the workpiece. The recesses 22, 23 provide cavities for fibrous debris generated by the respective tooth (24). When the screw is in place, the teeth (24) are resiliently pressed axially toward the thread produced in the workpiece to reduce the loosening tendency of the installed screw. The disposition and size of the cutouts (19-21), is about three cutouts per one convolute so as not to unduly impede the torque strength of the screw.

Abstract: A method for increasing the bandwidth of a uni-directional path switched SONET ring network by sacrificing protection of the information carried on the ring network. The method alters the way in which information is added into the ring at a node and how its is dropped at other nodes on the ring. Information added into the ring is added into only one of the two redundant paths of the SONET ring network, leaving the remaining path available to carry different, non-redundant information. Information dropped from the ring is also re-transmitted to down-stream nodes on the ring.

Title: Topology-independent priority arbitration for stackable frame switches
Inventor: SMITH MATT
IPC: H04L12/24
Filed: 1999-07-09
Abstract: A method and apparatus for allocating master priority to a unique one of a plurality of interconnected processors. A data storage register is provided for each processor. The registers and processors are interconnected to enable any processor to store data in all of the registers, and to enable each processor to read data stored in that processor's register. A unique multiple bit identifier is allocated to each processor. The processors are synchronized with one another, and master priority is arbitratively allocated to the processor having the lowest value identifier. The arbitration involves repetitively, for each processor which, has not previously been dismissed as a "master" candidate: ~ storing a predefined dismissal value in the processor's register; ~ selecting a next portion of the processor's identifier; ~ if the selected portion of the identifier has a value corresponding to a predefined non-dismissal value, actuating the processor to store the non-dismissal value in all of the registers; and, ~ if the selected portion of the identifier has a value corresponding to the dismissal value and if the non-dismissal value is stored in the processor's register, dismissing the processor as a "master" candidate; until all but one of the processors are dismissed as a "master" candidate.
