Patent CA-2544806-A1 (CA)
Title: Positional blasting system
Inventor: MCCLURE ROBERT
IPC: F42D1/055
Filed: 2004-11-04
Abstract: A blasting system facilitates the actuation of a plurality of programmable detonators according to a desired blasting pattern, to cause the discharge of a plurality of associated charges, by downloading to the detonators blasting information that can be automatically determined by a portable handheld unit that incorporates a positional detecting device, such as a GPS device. The blasting information for any given detonator can be determined by the handheld unit as a function of the distance and the direction of the movement of the unit to the detonator, and/or by the actual GPS location while at the site of the detonator. This automatic determination of blasting information, and particularly the delay times, based on the movement of the unit to the detonator, eliminates error prone human calculations of the delay times needed for multiple detonators at a blasting site. This simplifies the operations and procedures needed for achieving a desired blasting pattern, without sacrificing safety or quality.

Abstract: The invention relates to a process for producing a substantially stable dispersion without manufacturing aids, where the dispersion comprises at least one hydrophobic plant sterol and an aqueous material, wherein the plant sterol is selected from plant sterols and plant stanols. The process comprises mixing the plant sterol with the aqueous material to form a first dispersion, homogenizing the first dispersion to obtain a second dispersion of particles wherein the particle size of the hydrophobic plant sterol particles in the first dispersion and the second dispersion is from about 0.1 micron to about 100 microns. Optionally, the process may comprise heating the first dispersion prior to homogenizing, heating the second dispersion after homogenizing, or heating both. In one embodiment, the aqueous material comprises a beverage concentrate, which includes a juice concentrate, such as a citrus juice concentrate, e.g., an orange juice concentrate. In one aspect of this invention, in order to substantially avoid a powdery taste in the dispersion, the particle size of the plant sterol particles is from about 0.1 micron to about 30 microns and the majority of hydrophobic plant sterol particles within this range will be from about 0.2 microns to about 10 microns and will substantially follow a bell curve distribution.

Filed: 2005-06-01
Abstract: The invention describes a process for the determination of the concentration distribution and size distribution of lipoprotein classes in body fluids, e.g.  blood. For this purpose, NMR spectra of a sample to be analysed are measured by magnetic field gradient intensities and temperatures under different diffusion-weighted measuring conditions selected according to different pulse programs (e.g. PFG-STE, PFG-LED etc) and consequently in a differentiated manner according to the relaxation times. The different effects of these measuring conditions on the intensity/line form of the NMR signals of the individual lipoprotein classes are determined and permit the determination of a concentration distribution/size distribution of the individual lipoprotein classes.
