Title: Process for the racemization of atropisomeric bis (phosphine oxide) compounds
Inventor: SCHMID RUDOLF
IPC: C07F9/50
Filed: 2000-07-04
Abstract: The present invention is concerned with a novel process for the racemization of atropisomeric bis(phosphine oxide) compounds of formula I (see formula I) in their (S) or (R) or non-racemic form, for the preparation of optical active bisphosphine ligands, which form optical active complexes with transition metals. These complexes are used as catalysts in a number of asymmetric reactions. The racemization is thermal and carried out in high or low boiling solvent, under normal or elevated pressure at 10 5 to 3.5 x 10 7 Pa. The heating is performed in a system which allows heating up to 400°C (reactor, autoclave, aluminum block, round- bottom flask with heating/stirring mantle and the like) or by microwave irradiation or in the melt at a temperature from 260 to 400°C, preferably from 280 to 380°C, batchwise or in a continuous manner.

Title: Optical fiber connector tuning index tool
Inventor: LAMPERT NORMAN ROGER
IPC: G02B6/38
Filed: 2000-07-28
Abstract: A tuning index tool for use in determining the degree of tuning necessary for a tunable optical fiber connector has a first stationary member having a connector adapter affixed thereto and a second movable member within the first member and spring loaded with respect thereto. The second member has a connector adapter affixed thereto axially aligned with the adapter in the first member. The movable member is incrementally rotatable with respect to the stationary member by being pulled against the spring force to disengage the ferrules of connectors in the adapters, which are aligned in a split sleeve. rotation changes the orientation of the eccentricity vectors of the two connectors, and hence the insertion loss. Measurements of insertion loss are made, and the orientation of the connectors for minimum loss is noted. The number of incremental rotations of the tool indicates the incremental rotation of the ferrule of the connector under test, the eccentricity vector orientation of the other connector being known, that is necessary to achieve minimum insertion loss for the connector with connectors have a known eccentricity vector orientation.

Title: Virtual path asynchronous transfer mode switching in a processing satellite communications system
Inventor: FALK AARON D
IPC: H04Q3/52
Filed: 2000-09-06
Abstract: The present invention provides a method (100) for virtual path switching of an ATM cell on a processing communications satellite. The method includes establishing a set of VPIs (104), where each VPI is associated with an output port on the satellite. The method also includes establishing a set of VCIs (106), and assigning one VPI and one VCI to an ATM cell (108).      The ATM cell may then be transmitted to, and then received by an input port of the satellite (110). The method also includes determining an associated output port (114), and transferring the ATM cell to that output port (116). The VPI may be divided into a control subfield and a routing subfield, and the associated output port may be determined based on the routing subfield (808). The present invention may also provide for multicast switching (400). For example, the method may include providing at least one multicast routing table (404). The VPI assigned to the ATM cell may be associated with a multicast output port. Thus, the ATM cell may be transferred to that multicast output port (418) and then received at the associated multicast module (420). A multicast group of VPIs may then be determined (422, 424), and the ATM cell may be reproduced several times (426). The reproduced cells may be reassigned with a new VPI from the multicast group of VPIs (428), and the reproduced cells are once again presented to and received by an input port of the satellite (430).

Title: Method and apparatus for conveying generally flat articles
Inventor: FEUILTAULT DOMINIQUE
IPC: B65H29/42
Filed: 2000-09-07
Abstract: The method and apparatus for delivering generally flat articles one by one make use of first and second conveyors. The first conveyor has a top article-supporting surface operated at a first linear speed in a forward direction. In operation, a stack of generally flat articles lies on one side on this top article-supporting surface longitudinally of the first conveyor. The second conveyor is installed in series with the first conveyor, operates at a second linear speed higher than the first linear speed in the forward direction, slopes upwardly in the forward direction, and includes a plurality of generally parallel, rotative longitudinal screws having respective threads structured to engage a lower edge of the generally flat articles. According to the method, the generally flat articles are jogged and thereby separated from each other through slipping of the lower edges of these articles on the successive ridges and grooves of the threads of the rotative longitudinal screws. In operation, a rate of processing of the generally flat articles supplied from a discharge end of the second conveyor to a downstream article-processing equipment is measured, and the first and second linear speeds are adjusted in relation to this measured rate of processing. Preferably, article-detecting proximity sensors are mounted at the discharge end of the second conveyor, and the first and second linear speeds are adjusted also in relation to signals from these article-detecting proximity sensors.

The sorbent is produced by reacting a mixture of maleic anhydride copolymer, a bifunctional organic compound (hydrochinon, diethyleneglycol, hexamethylene diamine, glycerol, ethyleneglycol), and .alpha.-benzoin-oxime in the ratio of 1:(0.25-0.50):(0.75-0.5) in a polar organic solvent (dioxane, dimethyl formamide, or toluene) in the temperature range of 90 ~C - 95 ~C with constant stirring for 1 to 2 hours. The resultant product is then cooled to room temperature and flushed 35 times with cold water. A white stringy product results. This is dried and crushed. Particles of 1-2 mm in diameter are selected for the solid sorbent.

Filed: 1996-01-24
Abstract: Disclosed heroin arc processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic eaters a carboxylic acids, and other monomers. The polymerizations are catalysed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear a.olefins by the oligomerization of ethylene using as a catalyst system a combination of a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected $(a)diimine nickel complexes with ethylene.

Patent CA-2350466-A1 (CA)
Inventor: JOHNSON STEN EDWARD
IPC: G06F9/50
Filed: 1999-11-12
Abstract: In general, the invention is directed towards a multiprocessing system in which jobs are speculatively executed in parallel by multiple processors (30-1, 30-2, ..., 30-N). By speculating on the existence of more coarse-grained parallelism, so-called job-level parallelism, and backing of to sequential execution only in cases where dependencies that prevent parallel execution of jobs are detected, a high degree of parallelism can be extracted. According to the invention a private memory buffer is speculatively allocated for holding results, such as a communication message, an operation system call or a new job signal, of a speculatively executed job, and these results are speculatively written directly into the allocated memory buffer. When commit priority is assigned to the speculatively executed job, a pointer referring to the allocated memory buffer is transferred to an input/output (10) device which may access the memory buffer by means of the transferred pointer. In this way, by speculatively writing messages and signals into private memory buffers, even further parallelism can be extracted.
