Patent CA-2491572-C (CA)
Inventor: HIRSH JANE
IPC: A61K9/16
Filed: 2003-07-07
Granted: 2010-03-23
Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opiods. In the preferred embodiment, a drug is modified to increase its lipophilicity. In preferred embodiments the modified drug is homogeneously dispersed within microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles or drug particles are coated with one or more coating layers, where at least one coating is water insoluble and preferably organic solvent insoluble, but enzymatically degradable by enzymes present in the human gastrointestinal tract. The abuse-deterrent composition retards the release of drug, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is broken down or dissolved gradually within the GI tract by a combination of enzymatic degradation, surfactant action of bile acids, and mechanical erosion.

Title: Engine brake control pressure strategy
Inventor: BEAUCAIRE JAMES T
IPC: F01L9/10
Filed: 2004-09-14
Granted: 2012-01-10
Abstract: An engine (10) has a hydraulic system (28) that serves both fuel injectors (22) and hydraulic actuators (40) of an engine brake (38) that brakes the engine (10) by controlling exhaust gas flow during engine braking. Pressure of the hydraulic fluid is set by an injection control strategy when a brake control pressure strategy is inactive. When the brake control pressure strategy is active, braking of the engine (10) occurs when hydraulic fluid is delivered to the actuators (40). The brake control pressure strategy signals pressure of the hydraulic fluid supplied to the one or more actuators (40) that is in excess of a pressure determined by a brake control pressure strategy. The brake control pressure strategy then limits pressure of the hydraulic fluid.

IPC: G01N15/02
Filed: 2004-12-09
Granted: 2013-10-22
Abstract: On the basis of a series of reflection measurements on a liquid, parameters are calculated which describe a particle size distribution of particles in the liquid. In each reflection measurement, a signal beam is generated in the liquid and a value of a property such as the amplitude of a reflection on a particle in the signal beam is measured. Using maximum likelihood estimation, the parameters of the particle size distribution are estimated, on the basis of an expression for a probability of the measured values as a function of the measured values. The expression used contains a first factor for the probability of a reflection measurement of which a reflection with the measured value forms part, corrected with a second factor for the probability that there is not also a reflection with a dominating value of the property, which would mask the measured values, forming part of the reflection measurement.

Title: Low field mobility separation of ions using segmented cylindrical faims
Inventor: GUEVREMONT ROGER
IPC: H01J49/00
Filed: 2005-08-05
Granted: 2009-11-24
Abstract: A method of separating ions is disclosed. The method includes a step of providing a FAIMS analyzer region for separating ions, the FAIMS analyzer region including at least one region of segmentation. The segmentation permits ion trapping, and a combination trapping and gating that permits high efficiency of ions collection from continuous ion sources. The ions are separated in segmented FAIMS, according to their high-field mobility properties, and by using the method described herein according to their low-field mobility. The ions are separated by low field mobility using stationary potential gradients formed by voltages applied to the segments, and by traveling potential gradients of various shapes. The ions are separated along the longitudinal direction in cylindrical FAIMS, and may be detected in a time-of-arrival fashion as the ions leave the ion outlet of FAIMS or optionally the ions other than selected are caused to collide with the electrodes and only the selected ions transmitted. This is a high resolution separation, combining the ion properties at high-field, as well as the low-field mobility properties, for selection of specific ions from very complex mixtures.

Title: Fuel injector with vop loss resistant valve spring for emissions-compliant engine applications
Inventor: COWDEN GARY L
IPC: F02M63/00
Filed: 2005-09-27
Granted: 2010-06-08
Abstract: A fuel injector assembly for an emissions-based EMD 710 locomotive diesel engine. The fuel injector assembly includes a needle slidably positioned within a bore of a valve body of the injector assembly, where fuel pressure introduced into a bore chamber causes the needle to open a spray tip. A spring mounted within the bore forces the needle to close the spray tip when the fuel is not being applied. The spring is a dead coil spring including inactive coils where at least portions of the coils at both ends of the spring are in intimate contact with each other so as to reduce spring wear during operation of the assembly. Because the dead coil spring has reduced wear, the VOP set point of the fuel injector assembly can be reduced, which reduces NOx emissions.

Abstract: A die cushion device of a pressing machine, wherein a controller controls the opening of a proportional flow control valve to a proper opening to control a flow flowing out from the lower chamber of a hydraulic cylinder supporting a cushion pad before a slide collides with the cushion pad by using a die cushion pressure instruction instructed from an instruction device beforehand and a slide speed signal inputted from a slide speed detector. Thus, the occurrence of a surge pressure produced when the slide collides with the cushion pad at a high speed can be suppressed.
