Patent CA-2065309-C (CA)
Inventor: LEE ROBERT ARTHUR
IPC: B42D25/29
Filed: 1990-09-04
Granted: 2001-11-20
Abstract: A diffraction grating providing an optically var-fable image includes a pixellated diffraction grating in which each pixel is an individual optical diffraction grat-ing so that the pixellated diffraction grating when illumi-nated generates an optically variable image. In another aspect the grating in some or all of the pixels of a dif-fracting grating formed by a regular matrix of pixels is arranged such that a reproduction of the grating by ref-lection contact printing generates a zero-order pattern which is grossly flawed by Moire or Talbot fringe ef-fects. A method of forming the diffraction, grating in-cludes producing a counterpart pixellated diffraction grating of a substantially optically invariable image wherein each pixel of the optically invariable image is maped to a respective pixel of the pixellated diffraction grating: Each grating pixel is an individual optical dif-fraction grating of the associated pixel in the optically invariable image, so that the pixellated diffraction grit-ing when illuminated generates an optically variable rep-roduction of the optically invariable image.

Title: Method for recovering organic material in solvent extraction processes
Inventor: BANNACH SICHTERMANN GUSTAVO HO
IPC: B01D17/00
Filed: 1993-07-30
Granted: 1999-04-27
Abstract: A method for the recovery of organic materials trapped in the emulsions generated in solvent extraction plants.  The emulsions are first washed in aqueous solution.  The washed emulsions are then subjected to a mechanical breaking process in aqueous/organic dispersion, inducing the inversion of the continuity of phases in the emulsions and the release of the phases involved.  Subsequent separation of the phases by decanting enables the removal of significant quantities of solids and increases the overall recovery of the organic trapped in the emulsions.

Abstract: A method for the direct determination of the toxicity of a solid material by direct contact between the solid sample and a luminescent microorganism, consisting of the steps of forming a suspension of a luminescent microorganism in a 0.5 % to 6 % solution of NaCI or 20 % solution of sucrose in distilled water diluent and contacting a sample of the solid to be tested directly with the suspension of luminescent microorganisms. A control including the microorganism in the diluent is also prepared. The combination of microorganism suspension and solid sample is incubated for a sufficient time to allow for the toxicity of the sample to affect the metabolism of the living organism. During or subsequent to the incubation period the combined organism and sample are subjected to a separation step to separate a major portion of the particulate solid from the suspension of microorganisms. The light output of the separated suspension is determined and compared with the light output of the control to arrive at the change in light output of the microorganism due to contact with the solid sample.

Abstract: A tamper indicating package comprising a container having a neck with a threaded finish, an annular bead on the neck, a plastic closure which includes a base wall and a depending peripheral skirt having threads interengaging the threads of the container, and a tamper indicating band attached to the skirt by a plurality of weakened portions defining a line of severing. An annular flange extends axially upwardly and inwardly from the tamper indicating band toward the base wall of the closure and comprises a first continuous annular flange portion connected to the band by a hinge portion and a second portion. The second portion comprises a plurality of segment portions extending upwardly and inwardly from the first continuous portion with the free ends of the segment portions engaging beneath the bead on the container when the closure is threaded onto the container. The flange is bent intermediate its ends so that the second portion extends inwardly at a greater angle than the first continuous flange portion. The segments are separated by narrow slits such that when the closure is fully applied on a container, and the closure is rotated to remove the closure, the free ends of the adjacent segment portions engage a bead on the container and are moved radially inwardly and the sides of the slits adjacent the free ends contact one another in an interfering manner to inhibit reversal of the segment portions and enhance resistance to removal.

Abstract: A method of forming a magnetically anisotropic powder includes the steps of forming a substantially spherical powder having a major magnetic phase and an average particle size of less than about 200 microns, diffusing hydrogen into the spherical powder at elevated temperatures in an amount sufficient to disproportionate the major magnetic phase, and desorbing the hydrogen by heating the disproportionated powder under vacuum. The magnetic material from which the spherical powder is formed may be a rare earth-transition metal-boron alloy including at least one element from the iron group, at least one rare earth element, and boron. A method of forming a bonded magnet containing magnetically anisotropic particles further includes the steps of mixing the dehydrogenated powder with a binder to form a mixture, and aligning and magnetiz-ing the powder particles in the mixture in a magnetic field.    Bonded magnets containing spherical, magnetically anisotropic particles of the invention have intrinsic coercivities in excess of 7kOe.
