Abstract: ABSTRACT OF THE DISCLOSURE     A thermocompressor is disclosed as including a free piston which coasts upwardly and downwardly in a bypass region of a cylinder between cold and hot rebound chambers at cold and hot ends of the cylinder located at the top and bottom of the cylinder. A compressible fluid alternately flows downwardly and upwardly between the cold and hot cylinder ends via the cylinder bypass in response to the alternate upward and downward coasting of the piston. This alternate fluid flow, in conjunction with a thermal lag heating chamber, regenerator, and cooling chamber, causes an alternate heating and cooling of the fluid which produces a cyclical fluid pressure variation utilizable for driving a load. Although the regenerator, and generally the cooling chamber, are located in the bypass, the thermal lag heating chamber is located beyond the bypass and communicates separately with the lower or hot end of the cylinder for thermal lag driving of the piston during a hot rebound portion of the cycle. During the upward coasting of the piston, fluid is directed out of the hot end of the bypass in a substantially defined stream which flows through a portion of the volume of the hot cylinder end and thence into the heating chamber via e heating chamber inlet port and inlet conduit, thereby producing the required heating during coasting. The inlet port is positioned within the cylinder and very close to the lower or hot end of the bypass for capturing substantially all of the above-mentioned stream of fluid substantially independently of the choice of fluid. The lower or hot end of the free piston is concavely shaped such that it does not strike or undergo substantial frictional contact with the cylinder end-wall defining the inlet port and inlet conduit even though the lower edge of the piston moves below the port during the hot rebound.

Abstract: QUANTITATIVE ANALYSIS OF NUCLEAR MAGNETIC RESONANCE SPECTRA HAVING          SOLVENT PEAKS               Abstract of the Disclosure A method is described for the quantitative analysis of a solution in which the solvent produces a nuclear magnetic resonant (NMR) spectral peak that dominates the system.  A first spectrum containing the peak is made by operation of a nuclear magnetic resonant spectrometer at a first gain setting.  The NMR apparatus is a pulse-modulated, Fourier-transform type spectrometer. A second spectrum is produced in which a 180° pulse is applied to invert the spectral component magnetization followed after a period of time by a 90° pulse.  The period of time is sufficient to allow the solvent or component producing the unwanted peak to relax from the inverted state to a point where there is minimum magnetization along the longitudinal axis.  At this point, in many solutions the other components have completely relaxed so that the 90° pulse produces a free induction decay signal which, after undergoing the Fourier-transformation, yields a spectrum that does not include any significant peak due to the solvent.  Thereafter, the quantitative analysis is performed by measuring the areas under the respective component peaks and simultaneously solving a series of equations in which the weight of the various components is proportional to the respective areas under the peaks and to gain settings of the spectrometer.

Abstract: VIR-CONTROLLED COLOR CORRECTION FOR COLOR VIDEO SIGNAL RECEIVING APPARATUS     ABSTRACT OF THE DISCLOSURE     Hue and color saturation are controlled in response to a received VIR signal, the latter having a chrominance reference portion and a luminance reference portion.  The level of a pre-selected one or more demodulated color signals which are produced by the color demodulator in color video signal receiving apparatus is detected during the time that the VIR signal is received.  The level-detected demodulated color signal is used to produce a con-trol signal for controlling the hue or color saturation.  A storage circuit, such as a capacitor, is provided to store the control sig-nal throughout the duration which separates successive VIR signals.          A VIR detector is provided for detecting the presence of a VIR signal in the received video signal; and when the absence of a VIR signal from the received video signal is detected, the control signal storage circuit is preset to a predetermined value.  By so presetting the storage circuit, the time required for successful VIR-controlled color correction is minimized when the video signal receiving apparatus is switched from, for example, one broadcast channel which does not include a VIR signal to another broadcast channel which does include a VIR signal.          In a preferred embodiment, both hue and color saturation are controlled in response to a VIR signal.  The level of a selected color difference signal (R-Y), produced during the chrominance ref-erence portion of the VIR signal, is used to control hue; and the level of a simulated color drive signal (B), also produced during the chrominance reference portion of the VIR signal, is used to control color saturation.                             -i-
