摘要： A direct expansion ammonia refrigeration system and a method of direct expansion ammonia refrigeration is described and which includes a source of liquid ammonia refrigerant which is delivered in fluid flowing relation to a plurality of evaporator tubes which incorporate wicking structures, and which through capillary action facilitated by the wicking structures are effective for drawing liquid ammonia refrigerant along the inside facing surface of the evaporator tubes so as to substantially reduce any stratified and/or wavy flow patterns of the liquid ammonia refrigerant within the evaporator tubes. The invention further includes a novel accumulator vessel and heat exchanger vessel which are coupled in fluid flowing relation relative to the direct expansion ammonia refrigeration system and which facilitate the removal of water from the ammonia refrigerant in order to enhance the operation of the direct expansion ammonia refrigeration system.

摘要： A system for determining polarization of a gas comprises a container that contains the polarized gas. An oscillator circuit comprises an Nuclear Magnetic Resonance (NMR) coil that is positioned adjacent to the container. A pulse generator circuit is configured to generate an electrical pulse that may be transmitted to an optical cell through the NMR coil to excite the polarized gas responsive to a control processor. A Q-reduction circuit that is independent of the pulse generator circuit is configured to reduce oscillations in the oscillator circuit from the transmitted electrical pulse responsive to the control processor. A receive circuit is responsive to an electrical signal that is induced in the oscillator circuit due to the electromagnetic excitation of the polarized gas. The control processor is configured to determine the polarization of the gas based on the output signal of the receive circuit. A polarimetry circuit for determining polarization of a gas includes an NMR coil that may be configured to excite a polarized gas and be responsive to an electromagnetic signal generated by the excited, polarized gas. The polarimetry circuit has a reproducible polarization measurement variability of less than 2% when the NMR coil is exposed to a temperature in a range of about 0° C. to about 200° C. Moreover, circuit-to-circuit polarization measurement variability may be less than about 3%.

摘要： A radiation therapy system produces a treatment beam that is detected by an electronic portal imaging device (EPID) after it passes through the subject being treated. A chopper wheel modulates low energy components of the beam while leaving the higher energy components substantially unmodulated. Modulated components in the image signals produced by the EPID are detected and used to produce portal images.

摘要： A heat exchanger is described and which includes an exterior container having an internal cavity; a refrigerant distribution tube is positioned within the internal cavity and which is further coupled in fluid receiving relation relative to a first source of refrigerant; and a multiplicity of closely nested refrigerant tubes are located within the internal cavity and are further disposed in a closely spaced, radially outwardly oriented positions relative to the refrigerant distribution tube, and which additionally have a predetermined and similar length dimension, and individually form helical coils which have a given and similar length dimension, and a variable pitch, and which are further coupled to a second source of a refrigerant.
