  • Patent number: 10775858
    Abstract: A liquid immersion cooling tank includes a reservoir and a liquid flow tube. The reservoir contains an insulating coolant to immerse an electronic device. The liquid flow tube includes an adjusting member. The reservoir includes an inlet and an outlet. The inlet and the outlet are respectively arranged at opposite ends of the electronic device. The liquid flow tube is located inside the reservoir. The liquid flow tube is coupled to at least one of the inlet and the outlet. The adjusting member faces the electronic device to control an amount of inflow or outflow of the insulating coolant. When the electronic device is immersed in the reservoir for cooling, the insulating coolant flows through the electronic device. The liquid flow tube coupled to the inlet or the outlet of the reservoir uses the adjusting member to control the amount of inflow or outflow of the insulating coolant.

  • Patent number: 10413754
    Abstract: Radiotherapy is one of the most effective treatments for cancer and its success depends critically on accurate targeting and delivery of the correct radiation dose. Accurate dosimetry is therefore essential to maintain and improve patient survival rates. However, size and long wait times currently limit water and graphite based calorimeters to standards laboratories leaving field-based dosimetry to ionization chamber measurements which depend upon a reference field-specified calibration factor. It would therefore be beneficial to provide radiotherapy equipment operators a direct approach of clinical reference dosimetry wherein the dosimeter provides increased independence on dose, dose rate, radiation energy, and energy type, etc. It would be further beneficial for such novel clinical dosimeters to be compact, function as secondary standards used routinely for measurements and allow radiotherapy doses to be measured directly and in an absolute manner.

  • Patent number: 9004752
    Abstract: 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.

  • Patent number: 8746966
    Abstract: A thermoanalytical instrument, and especially a differential scanning calorimeter, has first and second measurement positions, a heater and a temperature sensor associated with each of the measurement positions, and a controller. The controller, which has an associated means for setting a predetermined temperature program, controls a heating power of the first heater to cause the temperature measured at the first position to follow the temperature program. The controller also controls both heaters to eliminate any temperature difference between the measured first and second temperatures. The controller also provides a means for determining the lower of the measured first and second measured temperatures and applies additional power to the heater associated with that lower measured temperature.

  • Patent number: 8708556
    Abstract: A thermal analyzer heats and cools a sample placed inside a furnace for measuring a thermal characteristic of the sample during heating and cooling. The thermal analyzer has a multilayer structure for covering the furnace and its surroundings so as to isolate the furnace and its surroundings from an external environment. The multilayer structure includes a multilayer wall with two layers formed of a material having high thermal conductivity and heat dissipation property. The two layers are spaced apart from one another to provide therebetween an interlayer that contains a substance having a heat capacity substantially equal to a gas contained in the furnace so that heat transfer between the two layers is minimized.

  • Patent number: 8668380
    Abstract: A method for operating a calorimeter and a calorimeter that is operable to perform the method, wherein the calorimeter has a reactor (1) for receiving a reaction medium, a reactor jacket (2), an in-reactor heater (4) controlled by means of a first controller (6), an outer temperature control unit (9) in thermal contact with the reactor and controlled by a second controller (10), and a measurement sensor (5) arranged in the reactor for determining a reactor temperature (Tr). The reactor temperature is controlled by the heat which is delivered to the reactor by the in-reactor heater and by the heat that is carried in and/or out by the outer temperature control unit. A dynamic control of the heating power of the in-reactor heater and of the outer temperature control unit is used to eliminate any deviation of the reactor temperature from a reactor set-point temperature.

  • Patent number: 8637138
    Abstract: A thin substrate has a layered structure on one surface, and can also have a layered structure on the other. Each layered structure can include a part of at least one patterned layer that, if patterned by photolithography, would frequently result in damage to the substrate due to fragility. For example, the substrate could be a 3 mil (76.2 ?m) or thinner polyimide film and one patterned layer could be a semiconductor material such as vanadium oxide, while another could be metal in electrical contact with semiconductor material. The layer part, however, can be patterned by a printing operation or can include a printed patterned artifact such as an uneven boundary or an alignment. The printing operation can be direct printing or printing of a mask for etching or liftoff or both. The layered structure can include an array of cells, each with layer parts on each substrate surface.

  • Patent number: 8613545
    Abstract: The present invention describes a scan adiabatic resistive calorimeter (SARC) 1 with ohm heating of the sample 20, which measures the heating enthalpy and is formed of an inner cylinder 11 and a couple of pistons 15 and 16, thus forming said elements a cylindrical chamber hermetically closed 10, which avoids that during its operation can be material losses by leaks. Pistons 15 and 16 have, in one of their ends an electrode 31 and 36 respectively and they pass the electrical heating flow through the sample 20. In reference to this electric flow, the applied power is calculated and therefore, the supplied heat to the sample 20, which is equal to the specific enthalpy. To assure that the whole of the electric flow is conducted through the sample 20, the inner cylinder 11 is electrically isolated.
