Patent CA-2369565-A1 (CA)
Title: Apparatus for crushing material
Inventor: BOND NEVILLE JAMES
IPC: B02C4/08
Filed: 2002-01-25
Abstract: An apparatus 10 for crushing materials such as rock, ore, coal, stone and the like includes two rolls 16A and 16B which are mounted in parallel to define a gap 18 therebetween. Chunks of material to be crushed are fed by a conveyor 12 into the nip 14 between the rolls. Each roll 16A and 16B is similar and includes longitudinally extending steps provided by outwardly extending faces and smoothly curved surface segments between the steps. When the rolls are counter-rotated at the same speed, the gap 18 is maintained substantially constant and effectively transversely reciprocates in location between limits defined by the outer extremity of the face of a step on one roll being located opposite the inner extremity of the face of a step on the opposite roll.  Compared to smooth roll crushing the invention provides for greater reduction ratios to be achieved at slower rotational speeds and using smaller diameter rolls.

Title: High efficiency turbine
Inventor: WHITE WILLIAM PETER
IPC: F01D1/36
Filed: 2000-07-14
Abstract: A turbine system (10) has a turbine (12) that uses an aeromatic hydrocarbon as a working fluid (18). The turbine discharges the fluid in vapor form against  a boundary layer on the inside of a rotor (166) where it condenses as it loses  its energy. The outside of the rotor is formed to define chambers which are divided into suction and discharge or pressure cavities by stationary and rotating seals. Apertures (236-237) connect the boundary layer to the pump chambers and apertures (158-160) are positioned as discharge ports so that a s the rotor rotates, it also pumps the working fluid into a closed loop system  in which it is reheated and reintroduced into the turbine through a nozzle (292). The fluid is heated by a fluid heater (394) that may be positioned in  the interior of the rotor.

Patent CA-2387834-A1 (CA)
Inventor: NEUDORF DAVID A
IPC: C01G53/00
Filed: 2000-10-13
Abstract: A process is provided for the direct recovery of nickel and cobalt from a nickeliferous oxide ore leach slurry by ion exchange. A nickeliferous ore is leached with mineral acid to solubilize the metals. The resulting leach slurry is contacted with ion exchange resin, which selectively loads the nickel and cobalt from the pulp. The resin is separated from the leach slurry by screening and then stripped with an acidic solution. After stripping, the resin is returned to the loading cycle. Nickel and/or cobalt can be recovered in substantially pure form from the eluate by known processes. The metal-depleted slurry proceeds to waste treatment and disposal. This process eliminates the difficult solid/liquid separation, which could otherwise be required to recover metals values from the pregnant leach slurry.

Title: Use of a cd40:cd154 binding interruptor to treat immunological complications of the eye
Inventor: LOBB ROY
IPC: C07K16/28
Filed: 2000-10-19
Abstract: The invention relates generally to the treatment and inhibition of immunological complications of the eye. Such complications include unwanted immune responses resulting in an ocular inflammatory disease, resulting from  a corneal or retinal graft transplantation or resulting from ocular angiogenesis, particularly ocular neovascularization. The invention relates in particular to the inhibition, treatment, or reversal of immune-system driven  rejection of grafted corneal or retinal tissue or cells in a recipient host and to the treatment or inhibition of ocular inflammatory disease or ocular neovascularization in a host. Compositions and methods disclosed herein capitalize on the discovery that immunological complications of the eye can be inhibited using a CD40:CD154 binding interruptor, either alone or in combination with another immunomodulator or immunosuppressor. An exemplary CD40:CD154 binding interruptor is an anti-CD154 monoclonal antibody, such as  an antibody having the antigen-specific binding characteristics of the 5c8 monoclonal antibody.

Inventor: LAMB KARL J
IPC: H02K49/10
Filed: 1997-03-13
Abstract: A magnetic coupling device has an electroconductive rotor (15) presenting a band (16,17) of electroconductive material and has a magnet rotor (14) with permanent magnets (26) which are slide-mounted to move radially outward responsive to centrifugal force in opposition to a spring (40) bias. When the magnet rotor is stationary the magnets are radially inward of the orbit of the electroconductive band, and when the magnets have moved outwardly when the magnet rotor is rotating, the magnets are spaced by an air gap from the electroconductive band so that eddy currents are induced in the band resulting in coupling of the rotors. The electroconductive rotor preferably has two such bands (16,17) positioned on opposite sides of the magnet rotor. The rotors may have sheaves mounted thereon.

Title: Interventions to mimic the effects of calorie restriction
Inventor: SPINDLER STEPHEN R
IPC: C12Q1/68
Filed: 2000-12-22
Abstract: Long term calorie restriction has the benefit of increasing life span. Methods to screen interventions that mimic the effects of calorie restriction are disclosed. Extensive analysis of genes for which expression is statistically different between control and calorie restricted animals has demonstrated that specific genes are preferentially expressed during calorie restriction.  Screening for interventions which produce the same expression profile will provide interventions that increase life span. In a further aspect, it has been discovered that test animals on a calorie restricted diet for a relatively short time have a similar gene expression profile to test animals which have been on a long term calorie restricted diet.

IPC: C08B30/20
Filed: 2002-10-15
Abstract: The present invention relates to the analysis of the structure and synthesis of branched polymers of biological origin and the effects of these parameters on the end use of the branched polymer. In particular, the present invention relates to the correlation of the kinetics of starch production to the usefulness of a particular starch in a given food or non-food application. The methods of the present invention are capable of showing the rates of all the different enzymatic processes that lead to a particular branched polymer structure. The present invention surprisingly teaches that the rate co-efficients of polymer chain propagation, termination and/or branching, as used in free radical synthetic polymer chemistry, can be used for analysing the kinetics of branched polymer synthesis in biological systems. In one aspect, the present invention provides a method of analysing the kinetics of branched polymer synthesis, which comprises (l) determining the absolute molecular weight distribution of individual branches of a polymer, and/or another property(ies) characterizing starch polymer microstructure, and (ii) using the absolute molecular weight distribution, and/or another property(ies) characterizing starch polymer microstructure, data obtained from step (i) to calculate the rate coefficient or rate of at least one of chain propagation, termination or branching during formation of the polymer, wherein the polymer is of biological origin. The data obtained from this method can be used as an indicator of the kinetics of branched polymer synthesis. Polymers obtained from different biological origins, especially different strains and/or mutants of the same species of organism and/or under different growth conditions, can be analysed and variations in the kinetics compared between the different sources of the polymer. These branched polymers from different sources can also be tested for their suitability for various end-uses (desirable characteristics) of the branched polymer. These two factors, kinetics and suitability for a particular end-use, can then be compared to establish a correlation between the rate of at least one of chain propagation, termination or branching and suitability for a particular end use. This ultimately allows a polymer to be analysed by the methods of the invention to ascertain suitable end-uses for the polymer without the need to conduct extensive trials on different end-uses, and/or test a polymer for a given end-use when it will clearly not be suitable for that end-use as predicted by the kinetic analysis.
