Title: Method and apparatus for reduction of call setup time using anticipation technique for multimedia applications in widely distributed networks
Inventor: AGRAWAL PRATHIMA
IPC: H04Q3/00
Filed: 1998-10-26
Abstract: In a widely distributed digital communication network call delays and eventual outcome are anticipated (i.e., expected call outcome) at the initiationof a call at an originating terminal and the call is completed by signal switching to its destination terminal and by decreasing the number of related message transfers between network controllers and hubs required to complete the balance of administrative refinements of the call connection. The routing steps for setting up the call trajectory to the destination hub are completed immediately before the administrative steps, such as authentication, access control, bandwidth availability etc., are performed. Administrative refinements subsequent to the preliminary call set up are performed in a distributive manner. Administrative and capacity items are determined and completed post route determination and computed or accessed in parallel making this information available for a final call set up. If this information is adverse the call is immediately terminated. In one aspect the processors for administrative and capacity determination are connected in a parallel manner and work concurrently.

Title: Optimization of cells for endogenous gene activation
Inventor: HONOLD KONRAD
IPC: C12R1/91
Filed: 1998-11-30
Abstract: The invention concerns a process for optimizing the gene expression in cells. A first aspect concerns a process for changing the expression of a nucleic acid sequence which is present endogenously in a eukaryotic cell by introduction of a heterologous expression control sequence into the genome of the cell by means of homologous recombination as well as site-specific recombinase-mediated excision of inserted foreign DNA and its replacement by further heterologous expression control sequences or/and amplification genes. In addition the invention concerns the introduction of one or several nucleic acid sequences to which an activator protein or an activator protein complex binds e.g. a hypoxia-inducible factor (HIF), into the genome of a eukaryotic cell by homologous recombination in order to change the expression of a target gene. Furthermore the invention concerns a process for testing the influence of 5' or 3' non-coding nucleic acid fragments on the expression of a target gene by determining the expression of a reporter gene. In addition the invention concerns a process for providing a DHFR-negative eukaryotic cell containing a recombinase target sequence as well as the expression of a nucleic acid sequence inserted into the recombinase target sequence.
Patent CA-2256457-A1 (CA)
Title: Passive internal references for the detection of nucleic acid amplification products
Inventor: LIVAK KENNETH J
IPC: C12Q1/68
Filed: 1997-06-03
Abstract: The invention relates to passive internal references for use in quantitating the formation of amplification products in a nucleic amplification reaction.  The internal amplification reference molecules of the invention comprise a first and second fluorophore joined together through a backbone connector. The first and second fluorophores are joined on the backbone in a configuration that permits the energy transfer from the first fluorophore to the second fluorophore. The backbone connector is selected so as not to bind to the target nucleic acid sequence under nucleic acid amplification conditions.  Preferably, the backbone connector is a polynucleotide. Another aspect of the invention is to provide passive internal reference molecule containing reagent compositions for use in nucleic acid amplification reactions. The compositions comprise the internal amplification reference molecule of the invention and a nucleic acid amplification reaction buffer. The reagent compositions, optionally, include additional components required for nucleic acid amplification reactions. The invention also provides improved methods of measuring the amount of amplification product in nucleic acid amplification reactions employing fluorescer-quencher probe assays, including methods for the real-time measurement of amplification product formation. The methods comprise the step of adding the internal reference molecule of the invention to the amplification reaction mixture. Fluorescence of the second fluorophore on the internal reference may then be measured and used to calculate changes in fluorescence of the fluorophore on a fluorescer-quencher probe.

Abstract: Electrostatic cartridges (10) having a gear housing assembly which blocks access to a toner fill hole (22) and which includes an interior gear housing component (18a) integral with a cartridge base (14) are remanufactured by severing the interior gear housing component (18a) and then reattaching it to the cartridge base (14) through the exterior gear housing component (18b). The one-piece interior gear housing assembly (18a) is severed preferably at a 5 degree angle relative to the cartridge base (14) providing unobstructed access to the original toner fill hole (22), thereby ensuring that the attachment bosses (30) on the cartridge base (14) are not damaged to an extent that would defeat their coupling function. Paired reattachment holes (40a, 40b and 42a, 42b) are formed in the interior and exterior gear housing components (18a and 18b) to allow them to be reattached to one another via screw (44) and nut (46) assemblies extending therethrough, where they may then be connected to the cartridge base (14) by screws (20).

Inventor: GAGNON PHILIPPE
IPC: B07C5/02
Filed: 1999-04-12
Abstract: An apparatus and a method for sorting items with a significant variance in size. This equipment utilises a series of paddle-style blades to convert a randomised array of conveyor-fed items first into a plurality of organised linear, one-by-one flows as is often required for machine-vision inspection, and secondly delivers elements of said flow into graded categories. In one embodiment, this system sorts skeins of herring roe, but the singulation stage may be used with equal utility on other product, especially where such product displays a wide variance in size. In said one embodiment, skeins are dumped, or otherwise delivered onto a conveyor, table, or other receiving surface. A first singulation stage of said apparatus divides, linearises, and separates a flow of said skeins so that said skeins are arranged lengthwise and conveyed onto a plurality of narrow inspection conveyors, through a grading station and onward to ejection stations. Said ejection stations employ air nozzles utilising the coanda effect to selectively remove said items from said narrow inspection conveyors. By utilising said air nozzles, a required separation between said items is minimised and solenoids controlling said air-flow may be mounted remotely and operate on a low volume of high-pressure air. Overall, gentle handling of a product being sorted is ensured.

Title: Lever handle door lock with adapter
Inventor: SHOR ILYA
IPC: E05B3/06
Filed: 1999-09-27
Abstract: A lever handle door lock keeps the lever handle horizontal and accommodates pre-manufactured doors with pre-drilled mounting holes at varying rotational orientations by providing a two piece adapter connection between the lever handle and a rose. The rose is mounted to the door via the mounting holes and includes a spring for returning the lever handle to horizontal. A first adapter piece is rotatably driven by the spring to return to a home position relative to the rose. A second adapter piece is connected to the lever handle and is adjustably connectable to the first adapter piece at different desired rotational orientations. Rotating the adjustable connection between the first and second adapter pieces changes the angle between the lever handle and the home position on the rose to bring the lever handle to horizontal regardless of the rotational orientation of the rose.
