| 20130086984 | SPECIFIC GRAVITY MEASURING APPARATUS - A specific gravity measuring apparatus includes a liquid bath, a measured object receiving member which is housed in the liquid bath via a support means in a non-contact manner and into and out of which a liquid within the liquid bath can freely flow, an aerial mounting member which is supported by the support means and on which a measured object is placed in order to measure gravity thereof in the air, and a weighing apparatus receiving and supporting the measured object receiving member via the support means. The weighing apparatus | 04-11-2013 |
| 20140041451 | Non-Radioactive Density Measurement In Oilfield Operations - The current application discloses a non-contact, non-radioactive densitometer system, comprising a curved tube containing an oilfield fluid, a mass measuring device connected to the curved tube, and a data acquisition system connected to the mass measuring device. The mass measuring device measures the mass of the curved tube and the data acquisition system calculate the density of the oilfield fluid in the curved tube. In one embodiment, the non-contact, non-radioactive densitometer system further comprises an antilog amplifier that is connected between the mass measuring device and the data acquisition system, where the antilog amplifier transforms the mass of the curved tube into an exponential value which is then fed into the data acquisition system. | 02-13-2014 |
| 20160025700 | METHOD AND PROBE FOR MEASURING BUOYANCY IN CONCRETE - The method can determine a density of concrete based on the measured buoyancy of a buoy immersed in fresh concrete contained in a ready mix drum and rotatable therein as the drum is rotated, the method can include obtaining a first measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete, obtaining a second measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete by rotation of the cylindrical wall, obtaining an indication of the buoyancy of the buoy in the concrete including factoring out the yield effect based on at least the first measurement and the second measurement. | 01-28-2016 |
| 20160047726 | Method and Apparatus for Optimizing Sorptive Storage of Gas - A system for optimizing storage of gas in a storage vessel includes a storage vessel, a gas supply source selectively coupled to the storage vessel to supply gas to the storage vessel, a pressure gauge to measure a pressure within the storage vessel, a plurality of adsorbent materials, a measurement device configured to determine at least one of a weight or a mass of at least the storage vessel, and a computing device. Each of the plurality of adsorbent materials is separately disposed in the storage vessel for individual evaluation. The computing device is communicatively coupled to the measurement device and configured to process information based on the measured weight or mass determined by the measurement device. The computing device is configured to determine a density, an adsorption capacity, and a deadsorption rate of each adsorbent material disposed in the storage vessel based on information determined by the measurement device. | 02-18-2016 |

| 20090282913 | METHOD AND APPARATUS FOR MEASURING THE VOLUME OF AN ANIMAL PAW - Disclosed is an improved method for measuring the volume of an animal paw, suitable for use in a rat paw edema assay. Also disclosed is a novel apparatus for measuring the volume of liquid displaced by the insertion of an object into a liquid filled cup ( | 11-19-2009 |
| 20140318240 | Soak Chamber and System to Measure the Seed Density Hydration Profile of Seeds - Apparatuses, systems, and methods for measuring the hydration profile of seeds during Soaking. In some example embodiments, the volume change of irregular-shaped seeds during soaking is measured as the difference in the volume for a given chamber and the volume of water to fill a chamber with seeds at pre-defined time intervals. A device according to some example embodiments of the present general inventive concept includes a soak chamber to hold the seed, a water bath as a source of the input water, and a measuring tank where the water volume can be determined with a level sensor. The soaking temperature is maintained constant by water baths with a circulating tank surrounding the soak chamber to reduce heat loss. | 10-30-2014 |
