Title: Electronic technique of identifying an effective drug for treating a cancer patient
Inventor: MALIN PATRICIA J
IPC: G01N27/06
Filed: 1991-04-03
Abstract: AN ELECTRONIC TECHNIQUE OF IDENTIFYING         AN EFFECTIVE DRUG FOR TREATING A CANCER PATIENT            ABSTRACT       Cancerous cells of a patient under treatment are added to a quantity of cell life supporting media along with a quantity of an anti-cancer drug that is a candidate for treating the patient. The electrical conductivity of the cell is monitored over time in order to determine the effect of the candidate drug to inhibit increases in volume or number of the cancerous cells.  Data on the effect of the same drug on normal cells of the patient may simultaneously be gathered so that a drug is chosen which will result in reduced side effects on the patient.  A computer system is provided for simultaneously monitoring a large number of media containers, thereby allowing the effects of more than one drug and/or more than one concentration of a given drug to be determined at the same time, within a period of a few hours  or a couple of days.

Patent CA-2086384-A1 (CA)
Inventor: DE OLIVEIRA BANDARRA JOAO JOSE
IPC: B01J31/24
Filed: 1992-12-29
Abstract: The present invention concerns a process for the recovery of a noble metal from an inorganic and/or organic residue in the form of a tellurium amalgam characterised by adding a solvent having a boiling point above 120°C to the residue, removing by distillation water  and other residual solvents having boiling points below the boiling point of the added solvent, adding the tellurium or reducible tellurium compound, and then refluxing at atmospheric pressure before separating the amalgam of the noble metal.       The process of the present invention also allows the simultaneous recovery of the tertiary phosphine as its oxide from a residue containing a tertiary phosphine by the further stages of concentrating the mother-liquors remaining after separation of the amalgam of the noble metal, recovering the added high boiling point solvent and isolating the tertiary phosphine in the form of its oxide by precipitation with water.

On the other hand, when the pointing device is set upside down by the user, ball 10 moves to the opposite side via gravitation.  Then ball 10 is inserted between stopper 8 and keyboard 1 and, as a result, keyboard 1 is fixed by ball 10. When the user spins ball 6, the ball moves in all directions in accordance with the user's operation.  Furthermore, when the user pushes coordinate converting unit 4, detecting switch 7 is pressed by protrusion 3, and then detecting  switch 7 is switched to the ON state.

Title: Dual fuel ultra-low nox combustor
Inventor: PILLSBURY PAUL WALTER
IPC: F23R3/36
Filed: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE           An ultra-low NOx gas turbine combustor having a dual fuel capability.  The combustor has a pre-mixing zone and a downstream combustion zone.   The pre-mixing zone has three concentric annular passages that surround a central diffusion-type dual fuel nozzle.  A gas fuel manifold distributes gas fuel around the inner and outer passages.  A plurality of dual fuel nozzles are disposed in the middle passage to distribute either gas or oil fuel around the middle passage.   The distribution of fuel around the passages allows the formation of lean fuel/air ratios, thereby lowering NOx formation.  In addition, swirl vanes are arrayed around the inner and outer passages and around each of the fuel nozzles.  A step increase in the flow area in going from the pre-mixing zone to the combustion zone creates vortices that tend to anchor the flame.
