摘要： The invention determines density of a sample while the sample is immersed in a gaseous medium having variable density. The apparatus includes a chamber for containing the gaseous medium and the sample, means for selectively varying the density of the gaseous medium over a range of densities, and means for producing electrical signals related to the density of the gaseous medium. In the chamber is a balance beam having a sample pan at a first end and a coil assembly at an opposing second end. Also at the second end of the beam is a first counter-weight having a volume and mass which is substantially equivalent to the volume and mass of sample pan, and which creates a moment that is substantially equivalent to the moment created by the sample pan. At the first end of the beam is a second counter-weight having a volume and mass which is substantially equivalent to the volume and mass of the coil assembly, and which creates a moment which is substantially equivalent to the moment created by the coil assembly. A magnet assembly is disposed adjacent to and magnetically interacts with the coil assembly. A controller provides a coil current to the coil assembly, thereby generating a magnetic field which interacts with the magnet assembly. According to the invention, the interaction between the magnetic field of the coil assembly and the magnet assembly applies a force to the second end of the beam to keep the beam balanced as the density of the gaseous medium in the chamber is varied over the range of densities. A computing device receives the electrical signals related to the density of the gaseous medium and the electrical signal related to the coil current, and calculates the density of the sample based thereon.

摘要： A float fitted with a magnet is immersed in the liquid whose density is to be measured. A generator sends a ramp current periodically to a main coil, thus causing a progressively increasing attraction towards the bottom of the float. At the moment the float sinks suddenly, a moment depending on the density of the liquid, the sudden movement is detected by a second coil which sets a flip-flop. At this time the intensity which caused this drop is recorded in a buffer storage unit. This information is subsequently stored, during the interval between two readings, in a second storage unit which controls the data indication units in a quasi-continuous manner.

摘要： The measuring device has bobs 10, 17 suspended from a weight 12 with wires 11, 16. The hook 13 of the weight 12 is hung from a suspensor thread 15 extending downwards from a balance 14. The weight 12 may be omitted by using the upper bob 10 for dead weight. The bobs 10, 17 and the wires 11, 16 may be coated with a coating layer unreactive to the melt 19 whose density is to be measured. The weights of the measuring device is measured by the balance 14 under the first condition that the lower bob 17 is immersed in the liquid 19 and the second condition that the bobs 10, 17 are both immersed in the liquid 19. The density of the liquid 19 is calculated from the two measured values without the influence of the surface tension of the liquid 19 applied to the wires 11, 16.

摘要： Apparatus and method are described for measuring and recording as a function of time the resultant-weight of a test object immersed in a fluid medium. The apparatus and method are particularly suitable for determining a change in a chemical and/or physical property of a material exposed to a fluid, and for measurements such as of the floating forces produced by buoyant pharmaceutical dosage forms. An electronic toploader balance, with a weight-transmitter device connected to an electromagnetic measuring module of the balance, is positioned above a container so that the lower end of the weight-transmitter device extends into a solvent within the container. The weight transmitter device performs the double function of holding the test object submerged in the solvent and of transmitting to the balance the reacting force, that is the resultant-weight of the test object.
