  • Patent number: 5178543
    Abstract: A trainer, mounted and housed within a mobile console, is used to teach and reinforce fluid principles to students. The system trainer has two centrifugal pumps, each driven by a corresponding two-speed electric motor. The motors are controlled by motor controllers for operating the pumps to circulate the fluid stored within a supply tank through a closed system. The pumps may be connected in series or in parallel. A number of valves are also included within the system to effect different flow paths for the fluid. In addition, temperature and pressure sensing instruments are installed throughout the closed system for measuring the characteristics of the fluid, as it passes through the different valves and pumps. These measurements are indicated on a front panel mounted to the console, as a teaching aid, to allow the students to observe the characteristics of the system.

  • Patent number: 5166627
    Abstract: A method and apparatus for determining the extent of contact between an electrically conducting tube and an electrically conductive tubesheet surrounding the tube, based upon the electrical resistance of the tube and tubesheet. A constant current source is applied to the interior of the electrically conducting tube by probes and a voltmeter is connected between other probes to measure the voltage at the point of current injection, which is inversely proportional to the amount of contact between the tube and tubesheet. Namely, the higher the voltage measured by the voltmeter, the less contact between the tube and tubesheet.

  • Patent number: 5127258
    Abstract: An improved apparatus is provided for sampling a gaseous mixture and for measuring mixture components. The apparatus includes two sampling containers connected in series serving as a duplex sampling apparatus. The apparatus is adapted to independently determine the amounts of condensable and noncondensable gases in admixture from a single sample. More specifically, a first container includes a first port capable of selectively connecting to and disconnecting from a sample source and a second port capable of selectively connecting to and disconnecting from a second container. A second container also includes a first port capable of selectively connecting to and disconnecting from the second port of the first container and a second port capable of either selectively connecting to and disconnecting from a differential pressure source. By cooling a mixture sample in the first container, the condensable vapors form a liquid, leaving noncondensable gases either as free gases or dissolved in the liquid.

  • Patent number: 4748592
    Abstract: In a vacuum, recording is conducted by exposing a solid surface to a neutral particle beam or an ion beam modulated with a recording signal and converged, thereby to locally develop a change in composition on the solid surface. Then, reproducing is conducted by exposing said solid surface to an electron beam, an ion beam or a neutral particle beam which has been converged, thereby to emit electrons from the solid surface, and detecting the emitted electrons to read out the change in composition. If necessary, erasing is conducted by exposing the solid surface to the same beam as used in reproducing, thereby to eliminate the change in composition.

  • Patent number: 4744295
    Abstract: A printing mechanism is described comprising a plurality of type carriers (12, 34) which on their outer peripheral face carry in one region printing types and in another region indicator types (44). The printing types can be brought by turning the type carriers (12, 34) into a printing position. A setting means (32, 20, 24) including an actuating knob (32) can be brought into a drive connection with each of the type carriers (12, 34) for rotation thereof. Stop means (100, 102, 104, 106, 110) limit the turning travel of the type carriers (12, 34). With a detent moment governed by their spring hardness resilient detent elements (96) hold the actuating knob (32) against a rotation relatively to the type carrier (12, 34) in drive connection with the setting means (32, 20, 24), the detent moment being greater than the torque necessary to rotate the type carriers (12, 34).
