Abstract: ABSTRACT OF THE DISCLOSURE      To measure stomatal resistance of a leaf, signals are obtained from:  (1) a small thermocouple positioned adjacent to the leaf in a cuvette to measure tempera-ture of the leaf without conducting excessive heat;          (2) a thermistor in the cuvette chamber; and (3) a moisture sensor in the chamber.  The moisture signal automatically controls a magnetically operated bypass valve from a source of air flowing through the cuvette chamber  so that the moisture remains constant while the flow rate of the air is varied.  The flow rate is measured in a flow meter having two laminar paths in series, composed of equal-length equal-diameter tubes but differing in the number of tubes, with the flow rate being measured in a different one of two tubes in each path for different scale measurements.

Abstract: L'invention est relative à un circuit filtre qui agit comme un filtre passe-bas qui possède une grande constante de temps. Le circuit filtre comprend un circuit d'entrée qui reçoit un signal de tension à être filtré. Un circuit d'addition compare ce signal d'entrée à un signal analogique de sortie d'un circuit accumulateur et émet un signal d'écart correspondant à la différence entre les signaux d'entrée et de sortie. Ce signal d'écart alimente un oscillateur commandé par variation de tension qui génère un signal de fréquence proportionnel au signal d'écart. Ce signal de fréquence est divisé par un coefficient de division prédéterminé à l'aide d'un circuit diviseur de fréquence faisant partie de l'accumulateur pour contrôler la basse fréquence de coupure du circuit filtre de sorte à en accroître le temps de réponse. Un accumulateur intègre alors le signal de fréquence divisé. Le signal analogique de sortie est formé à partir du signal de fréquence intégré .

Abstract: ABSTRACT OF THE DISCLOSURE         A method for producing a sealed rope of braided or twisted filaments.  Heat-shrinkable filaments are braided or twisted about a core of a thermoplastic material to form a rope and the rope is placed under tension and treated to cause the thermo-plastic core material to melt.  Simultaneously the rope is main-tained at a temperature sufficient to cause the heat-shrinkable filaments to shrink but not to melt, whereby the shrinking of the filaments, while the rope is under tension, reduces the cross section of the rope and causes the material to penetrate into the openings between and to surround and seal the filaments of the rope.

Abstract: ABSTRACT      A low temperature method for the cleaning and disin-fection of heat and liquid-sensitive articles that are brought into physical contact with patients during diag-nostic evaluation, surgery or therapy.  These articles, such as endoscopes, bronchoscopes and related equipment are thus subject to contamination by microorganic pathogens and consequently may serve as transmittal agents for noscomial infection.  In the method of this invention, quick, pene-trating and adequate disinfection can be obtained by the use of a vapor consisting essentially of from 40 to 100% isopro-panol and the remainder consisting predominantly of water vapor. The aforesaid articles are brought into direct contact and totally enveloping contact with the vapor at a temperature between 45°C. and 65°C. for a period effective to destroy the pathogens.     When the articles are then removed from vapor contact, any condensed isopropanol on the surfaces of the article quickly evaporates.  This method can be operated in a disinfection chamber at constant atmospheric pressure or a vacuum can be drawn prior to introduction of the vapor into the chamber.  disinfection generally results in from 1/2 hour to 1 1/2 hours, with shorter times possible in the vacuum cycle.

Abstract: ABSTRACT A pumpable slurry of pulverized coal in a coal-derived hydrocarbon oil carrier which slurry is useful as a low-ash, low-sulfur clean fuel, is produced from a high sulfur-containing coal. The initial pulverized coal is separated by gravity differentiation into (1) a high density refuse fraction containing the major portion of non-coal mineral products and sulfur, (2) a lowest density fraction of low sulfur content and (3) a middlings fraction of intermediate sulfur and ash content. The refuse fraction (1) is gasified by partial combustion producing a crude gas product from which a hydrogen stream is separated for use in hydrogenative liquefaction of the middlings fraction (3). The lowest density fraction (2) is mixed with the liquefied coal product to provide the desired fuel slurry. Preferably there is also separately recovered from the coal lique-faction LPG and pipeline gas.
