摘要： Apparatuses and methods are disclosed for performing a light-absorption measurement on a test sample and a compliance measurement on a reference sample. A method includes moving a reference sample receptacle carrier of an apparatus to position a first reference sample receptacle received in the carrier at a second position in a light path, directing light from an illumination system to a detection system along the light path to perform a light-absorption measurement on a first reference sample at the second position, moving the carrier to position the first receptacle out of the light path, placing a test sample receptacle in a test sample receptacle holder of the apparatus in the light path at a first position different from the second position, and directing light along the light path to perform a light-absorption measurement on a test sample in the test sample receptacle holder at the first position.

摘要： A weigh module (1) includes a load cell (2), a base plate (3), a top plate (6), a force-transmitting member (3) serving to transmit the weighing force from the top plate (6) to the load cell (2), and movement-restricting means (9, 10) which serve to limit the horizontal floating movement of the top plate (6) relative to the base plate (3) within a confined range of free play and to transmit lateral force components directly from the top plate (6) to the base plate (3). One part of the movement-restricting means (9, 10) has the form of a channel whose top edges (11) are rigidly connected to the top plate (6) and whose flat bottom extends parallel to the base plate (3) at a clear distance from the latter. The other part of the movement-restricting means (9, 10) is a bolt whose shaft (15) is anchored in the base plate (3) and passes with all-around clearance through a passage (14) in the channel bottom (13), and whose head (16) is larger than the passage (14) and arranged above the channel bottom (13) with a vertical clearance gap from the latter

摘要： 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.

摘要： A container is filled to a predetermined target mass of a free-flowing substance with the help of a device that dispenses measured doses of the substance. The device has a valve for variably adjusting the mass flow rate of the substance from a reservoir into the container. The device further includes a means for measuring the elapsed time from the beginning of the filling process, a balance for determining the mass of the substance in the container, and a controller unit for controlling the valve. The controller unit includes an adjustment module, and a memory unit wherein a desired mass flow rate is stored. At an elapsed time, if the mass flow rate is smaller or larger than the desired mass flow rate the flow rate is respectively increased or decreased by a flow rate adjustment.

摘要： A sampling device allows samples to be taken from a fluid that is pressurized and/or contains volatile components. The sampling device has a sampling housing (121, 521), an inlet (10, 110, 510), an outlet (11, 111, 511), a measuring cell (17, 317, 517) and a valve unit (118, 534). The valve unit has a valve which, in a first position, connects the inlet to the outlet by way of the measuring cell. In a second position, the valve connects the inlet directly to the outlet, while also disconnecting the measuring cell from both the inlet and the outlet. The valve unit also has at least one adjustable flow restrictor, through which the flow of the fluid through the sampling device is regulated.

摘要： 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.

摘要： A system and method for releasably coupling an extendable element to an actuator. Such a system may include an actuator housing with a specially adapted integral connecting end having a cavity therein. An extendable element may extend into the cavity through an opening in the connecting end of the housing and be coupled to a motive element of the actuator by a rotatable collar that resides in the cavity. A cover plate forms a part of the actuator housing connecting end. The cover plate compliments the integral portion of the connecting end and, in conjunction therewith, encloses the collar and the coupled portion of the extendable element. A substantially hollow end cap is passed over the extendable element and releasably attached to the actuator housing to enclose the distal connecting end thereof. In some embodiments, the coupled extendable element may reciprocate within an outer tube that is also releasably attached to the actuator housing.

摘要： The disclosed embodiments describe force-transmitting devices for use in gravimetric measuring instruments. The force-transmitting devices scale the force from a calibration weight to facilitate calibration and weighing. The devices comprise unidirectional coupling elements. The unidirectional coupling element comprises coupling element parts. The elements may be adapted to transmit only a tensile force or only a compressive force to a measurement transducer. Adapting the unidirectional coupling element to transmit one type of force or the other may be done by selecting an appropriate arrangement of coupling element parts. The coupling element parts are adapted to transmit force along a midline axis by either a projection and v-shaped groove coupling or projections on the first part mated with surfaces on the second part adapted to receive and guide the first part.
