Patent number: 9004752Abstract: A viable strategy to enhance the bioavailability of poorly soluble drugs is to use amorphous solids in place of the more commonly used crystalline solids in pharmaceutical formulations. However, amorphous solids are physically meta-stable and tend to revert back to their crystalline counterpart. An effective approach to stabilizing an amorphous drug against crystallization is to disperse it in a polymer matrix. The drug's solubility in the chosen polymer defines the upper limit of drug loading without any risk of crystallization. Measuring the solubility of a drug in a polymer has been a scientific and technological challenge because the high viscosity of polymers makes achieving solubility equilibrium difficult and because pharmaceutically important drug/polymer dispersions are glasses, which undergo structural relaxation over time. The invention provides a method based on Differential Scanning calorimetry (DSC) for measuring the solubility of crystalline drugs in polymeric matrices.Type: GrantFiled: April 29, 2009Date of Patent: April 14, 2015Assignees: Abbvie, Inc., Abbvie Deutschland GmbH & Co KG, Wisconsin Alumni Research FoundationInventors: Geoff G.

A method using the measuring instrument has at least the steps of determining the change over time of the sample as a function of temperature based on the recorded image/time data and actual temperature/time data, and of determining the dropping- or softening point of the sample based on the observed change over time as a function of temperature.Type: ApplicationFiled: August 28, 2012Publication date: March 7, 2013Applicant: METTLER-TOLEDO AGInventors: Mario Crevatin, Markus Tuor, Benjamin Arnold, Pascal Wildbolz, Daniel Scherrer

Publication number: 20130016755Abstract: A brake oil boiling point detector includes a handle, a positioning base, a thermometer, a heater, and a level detector. The positioning base is combined with the handle using a fixing part. The positioning base has spaces for brake oil to enter via through holes. The level detector heats and boils the brake oil when detecting that the height of the brake oil is sufficient for the heater to be immersed. The thermometer detects the boiling point and displays the temperature.Type: ApplicationFiled: July 15, 2011Publication date: January 17, 2013Inventor: Tien-Tsai TSENG

Patent number: 8348500Abstract: A hygrometer and dew-point instrument is provided that is structurally simple while reducing the workload during maintenance. The hygrometer measures relative humidity of a measurement space, and has a main body that encapsulates a working fluid therein and causes a heat-pipe phenomenon. The main body is disposed across the measurement space and an external space spaced from the measurement space by a heat-insulating part and has a temperature lower than the measurement space. A first temperature deriving part derives the temperature of the main body in a section where the working fluid evaporates. A space temperature detecting unit detects the temperature of the measurement space. A computation unit calculate relative humidity of the measurement space based on the temperature of the main body derived by the first temperature deriving part and the temperature of the measurement space detected by the space temperature detecting unit.Type: GrantFiled: March 26, 2008Date of Patent: January 8, 2013Assignee: Espec Corp.Inventor: Shinichirou Sakami

Patent number: 8292501Abstract: A cryogenic turbo-pump with an inducer and a system for detecting an onset of cavitation at the blade tips of the inducer. An IR imaging sensor is used to view the blade tips during operation of the turbo-pump for a temperature drop that indicates the onset of cavitation. The imaging sensor includes a means to vary the image capture rate to that the rotating blade tip will appear to be stationary in order to measure the blade tip temperature. A window is formed in the inducer housing in which the imaging sensor can view the blade tips during operation.Type: GrantFiled: March 22, 2011Date of Patent: October 23, 2012Assignee: Florida Turbine Technologies, Inc.Inventor: Elizabeth V Stein

Publication number: 20120155505Abstract: In a method for detecting the freezing of water within a fuel cell, precise detection can be performed using a phenomenon specific to the time when water starts to freeze to allow a reduction in erroneous activation. Detection at an early stage after the start of freezing is allowed, and hence measures can be taken against an output reduction before the water within the fuel cell completely freezes.Type: ApplicationFiled: February 23, 2012Publication date: June 21, 2012Applicant: CANON KABUSHIKI KAISHAInventors: Akira Morita, Jun Yamamoto, Kazuyuki Ueda, Taihei Mukaide

Patent number: 8201992Abstract: New sensors and methods for qualitative and quantitative analysis of multiple gaseous substances simultaneously with both high selectivity and high sensitivity are provided. The new sensors rely on a characteristic difference in energy between the interaction of a particular substance with a catalyst coated heat transfer device (HTD) and a non-catalyst coated (or one coated with a different catalyst) reference HTD. Molecular detection is achieved by an exothermic or endothermic chemical or physical reaction between the catalytic surface of the sensor and the molecule, tending to induce a temperature change of the sensor. Both high temperature and non-destructive low temperature detection are possible. The magnitude and rate of endothermic or exothermic heat transfer from a specific molecule-catalyst interaction is related to molecular concentration.Type: GrantFiled: November 6, 2007Date of Patent: June 19, 2012Assignee: Sensor Tech, Inc.Inventors: Michael L. Horovitz, Karl F. Anderson
