Patent CA-2297971-A1 (CA)
Inventor: PETERSON CRAIG A
IPC: G06F9/44
Filed: 1998-07-31
Abstract: The shared multi-user communication system allows a group of users to explore, navigate, manipulate and examine application data in a multi-dimensional synthetic environment. A shared user state and parameter table storing the attributes of the data being examined at each synthetic environment system within the group is stored locally at each synthetic environment system. A  shared control table defines which parameters of the data locally examined are to be controlled by the local user and which attributes are to be controlled by a remote synthetic environment system. Thus, data may be examined at the local station fully independent from the examination of data at remote stations. Alternatively, the data examined at the local station may be partially or wholly synchronized to the examination of data at remote stations. An override table is further provided to enable data being examined at the local station to be maintained privately and not transmitted to the remote synthetic environment systems of the group. For security purposes, a group establishement protocol prevents a group from being established without every group member approving every member's membership in the group.

Abstract: A method of installing tiles via interposed tile carriers on a scroll of a centrifuge comprises mounting each tile carrier (11) prior to a welding step in the required position on a centrifuge flight by means of an individual tile clamp (32), with mechanical inter-engagement between each carrier (11) and its clamp (32), thus positioning each carrier (11) in the same position relative to its clamp (32) on each application, the tile clamps (32) being of a set width, so that when mounted side by side they pitch the carriers (11) so that when the tiles (10) are inserted there are no gaps between the tiles, thus giving a smooth surface without having to dress the tiles. Mounting is followed by welding the carriers (11), whilst held in position by the tile clamps to the centrifuge flight. The tile clamps; are then removed and once the tile carriers have cooled down to ambient temperature the tiles. (10) are inserted and secured to their respective carriers (11). The invention also includes a method of inserting a dovetail ribbed tile (10) into a dovetail grooved carrier (11), and also a centrifuge flight (31) or scroll incorporating such tiles and carriers, and also a centrifuge incorporating such a scroll.

Title: Method and apparatus for queue management
Inventor: FIROIU VICTOR
IPC: H04L12/56
Filed: 2000-06-01
Abstract: A method, apparatus, and computer program product for determining a drop probability for use in a congestion control module located in a node in a network is disclosed. A weight value for determining a weighted moving average of a queue in a node is first systematically calculated. The weighted moving average is calculating and an average queue size for the node is determined based upon the weighted moving average. A control function associated with the congestion control module is evaluated using the average queue size to determine the drop probability. The weight value may be calculated by first determining a sampling period for measuring the queue size. Next, a time period for which samples significantly contribute to the average queue size is calculated. The weight is determined based upon the sampling period and the time period. In a further embodiment, the control function is calculated based upon a queue function where the queue function is calculated based upon predetermined system parameters. The control function may be selected based upon a queue policy for management of the queue. From the queue policy a threshold value which lies along the queue function curve is determined. This point provides a minimum value for the maximum point of the control function so as to avoid oscillations within the buffer. A maximum point may then be selected which resides outside of the curve for the queue function. The control function may then be selected so that the control function crosses through the maximum point. Thus, when the congestion control module drops packets based upon the drop probability determined by the control function the queue will not oscillate.

Title: Method of parallel screening for insertion mutants and a kit to perform this method
Inventor: MAES TAMARA
IPC: C12Q1/6809
Filed: 1998-11-23
Abstract: The current invention is a novel approach termed "parallel screening" which allows to simultaneously screen a population for insertions in all genes cloned from that or a closely related organism. In order to test this approach the flowering plant Petunia hybrida was used as a model system. Petunia hybrida line W137 contains a high copy number of the endogenous transposable element dTph1 and has been presented as a genetic tool before (Gerats et al., 1989). A 3D library of the plant genomic DNA of 1000 Petunia hybrida W137 plants was generated as described by Koes et al. (1995). The 3D library consists of 30 pools of DNA from a 100 plants each. These were used to generate 30 pools of insertion flanking sequences by nested iPCR using a set of transposon specific primers or by Transposon Display PCR. Insertions into a gene were detected by hybridizing the amplified insertion flanking sequences fixed to a filter with a gene specific probe, an approach termed simple screening for insertion elements. Alternatively, the amplified insertion element flanking sequences were labeled and used as a probe to hybridize a filter displaying multiple gene targets, an approach termed parallel screening for insertion elements, which allows the simultaneous screening for insertions in all genes of an organism, appearing in a population of insertion mutants.

Filed: 2000-07-10
Abstract: A gas bolt heater for loosening large bolts and studs has a hollow cylindrical housing defining a cylindrical chamber within the housing. A heating tube projecting from one end of the housing has a longitudinal bore. A first cylindrical insert closing the lower end of the chamber has a through opening communicating with the bore of the heating tube, and a second cylindrical insert located within an opposite end of the cylindrical housing has an elongate passage extending axially of the cylindrical housing. Downwardly convergent air passages in the second cylindrical insert have mouths distributed around the elongate passage, at a lower end of the passage, and an air supply duct communicates through the cylindrical housing with the air outlet passages. In use, air jets discharge from the mouths of the air outlet passages around an outlet end of a tip of an oxy-acetylene torch inserted through the elongate passage so that the flame of the oxy-acetylene torch is directed longitudinally of the cylindrical chamber and does not impinge directly on the wall of housing. The useful life of the gas bolt heater is thereby substantially extended.

Title: Capacitive mounting arrangement for securing an integrated circuit package to a heat sink
Inventor: AHL BENGT
IPC: H01L23/40
Filed: 1999-03-29
Abstract: A thermally conductive mounting flange of an IC package is placed directly on a heat sink surface between respective sections of single layer PC board attached to the heat sink, such that electrical leads extending from opposing sides of the package are positioned over corresponding conductive areas formed on the surface of the respective adjacent PC board section. The leads are electrically coupled with the conductive areas by respective tie-down screws fastened through dielectric isolating washers. The screws are tightened sufficiently against the isolating washers so as to press the respective package leads into solid electrical contact with the conductive areas. Portions of the respective leads and conductive areas surrounding the tie-down screws are cut away to prevent electrical contact, in order to avoid shorting the leads and/or conductive areas to the heat sink via the tie-down screws. Alternately, respective ends of a retaining spring used to secure the IC package to the heat sink mounting flange are also secured by the package lead tie-down screws, such that the screws both secure the package against the heat sink and press the package leads into solid electrical contact with the respective conductive areas.
