Patent CA-2272887-A1 (CA)
Inventor: HAGER JAMES W
IPC: H01J49/42
Filed: 1997-10-28
Abstract: Un procédé de mise en oeuvre d'un spectromètre de masse ayant un ensemble tige consiste à diriger des ions à l'intérieur de l'ensemble tige, à appliquer à l'ensemble tige une tension RF non équilibrée, et à appliquer à l'ensemble tige une tension C.C. de résolution de faible niveau (comprise entre 0,3 et 15,5 volts, par exemple), ce qui permet d'augmenter la sensibilité du spectromètre de masse et d'en améliorer la résolution. Dans une autre forme de réalisation, au lieu d'appliquer une tension RF non équilibrée à l'ensemble tige, on applique une radiofréquence correctement synchronisée à une lentille terminale placée à distance de l'extrémité de sortie de l'ensemble tige.

Patent CA-2274280-A1 (CA)
Inventor: JACKSON ARNOLD H
IPC: B03C7/12
Filed: 1999-06-10
Abstract: An apparatus and a process for subjecting a free falling stream of particles to an electrostatic field, between two rows of oppositely charged electrostatic rotating electrodes to effect a separation between particles of different electrostatic properties; the electrodes and cleaning brushes being suspended vertically and driven from their upper ends and having free lower ends. The electrode bearings are gently flushed with air from inside the electrodes and brushes to minimize the accumulation of dust thereon. The feed stream is baffled to minimize any lateral movement of the feed particles.      The electrodes are fitted with commutator mechanisms to permit efficient and unchanging electrical charging of the electrodes without a separate connection from the power source to each electrode, i.e., the charging is from one to the next adjacent electrode.

Title: Ligand-mediated immunofunctional hormone binding protein assay method
Inventor: CARLSSON LENA MARIANA SUSANN
IPC: A61K38/30
Filed: 1991-11-19
Abstract: A ligand-mediated immunofunctional assay (LIFA) method for detecting the presence and the concentration of polypeptide hormone binding proteins which comprises capturing the binding protein with a solid phase bound first antibody, saturating the bound hormone binding protein with the ligand polypeptide hormone, and detecting the bound ligand polypeptide hormone with a detectably labeled second antibody specific for the ligand polypeptide hormone. In the absence of added saturating polypeptide hormone, the LIFA measures the amount of hormone binding protein bound to the endogenous ligand polypeptide hormone. A growth hormone binding protein assay illustrates the method of the present invention. LIFA  assay results indicate that increased binding protein substantially increases growth hormone activity. Methods of use and formulations of growth hormone binding protein, growth hormone, insulin-like growth factor-I and insulin-like growth factor binding protein are disclosed.

Inventor: MALSBENDER DIETER
IPC: F41G3/26
Filed: 1998-10-10
Abstract: The invention relates to an measuring head for a simulator for simulating the firing of especially long-range weapons. The inventive measuring head has an illumination emitter (10) for illuminating a target with a pulsed laser beam in order to simulate fire, a receiver (11) for the laser light reflected in the target and a signal processing element (12) for determining the spatial and temporal position of the target. The laser beam emitted by the illumination emitter (10) is a vertical laser line which illuminates a defined solid angle (emittance angle) homogeneously and which can be deflected horizontally. This enables several targets to be detected with high resolution in a relatively large measuring field. The receiver (11) has a vertically oriented high resolution detector line (14) with a solid viewing angle which is identical to the emittance angle. The detector line (14) is made up of a plurality of individual detector elements (141) arranged one above the other.  An independent channel (121) is allocated to each detector element (141) for processing signals. The illumination emitter (10) and the receiver (11) are synchronised with each other in such a way that the emittance angle and the viewing angle of the detector line are congruent at all times.

IPC: G01L1/25
Filed: 2000-01-13
Abstract: A method for measuring the torque in a shaft 10 using the acousto-elastic effect. An electromagnetic acoustic transducer (EMAT) 14 generates two orthogorial wave pulses 5 which propagate along the surface of the shaft at ~ 45° to the shaft's longitudinal axis 4 and are detected by a second EMAT 16. The two waves travel along the lines of principal tensile 1 and compressive 2 stress and their velocity is therefore affected by applied torque such that the difference in their velocity is a measurement of the torque applied to the shaft 10.
