Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method for dry cooling coke using the sensible heat which is formed during the dry cooling.  According to the invention, a combustible gas which is used as a circulating gas, after leaving the waste gas steam boiler and before entering the coke cooling chamber, is cooled down approximately to coolant temperature in a combined washer cooler thus removing dust therefrom.  Further-more, the circulating waste gas leaving the said washer cooler is passed through a cooling unit such as a heat pump like unit before entering the coke-cooling chamber. Adjustment of the calorific value of the combustible gas is effected by feeding nitrogen or cleaned flue gas into the cold circulating gas ahead of the coke dry cooler and/or by feeding air into the hot circulating gas after the dry cooler.  Ahead of the dry cooler, excess cold circulating gas is withdrawn and is mixed with the under-grate-firing gas fed to the coke ovens.          The excess circulating gas may be withdrawn between the dry cooler and the preheating unit, it may be passed through a waste gas boiler, and mixed with the gas leaving the said preheating unit.  The operating temperature may be adjusted by feeding the cooled gas into the duct running from the dry cooler to the said preheating unit.

Abstract: ABSTRACT         There is described a snorkel mast for a submersible vehicle.  The mast terminates at the upper end in an inverted U-shaped snorkel head pipe section closed by a butterfly valve.      The butterfly valve is operated by a bell-crank lever having a float at one end and a water impact flap at the other.  Operation of the bell-crank lever by water level action against the float or by water impact action on the flap if a wave washes over the top of the snorkel mast acts to close the butterfly valve.  The mast carries a fairing which comprises a number of fairing elements of airfoil cross-section, vertically spaced on the mast so as to be freely rotatable thereon in water lubricated bearings.  The seg-mented fairings on the snorkel mast maintains hydrodynamic stability during high speed turns.

Abstract: METHOD AND APPARATUS FOR ANALYZING A POROUS NONHOMOGENEOUS                 CYLINDRICAL OBJECT            ABSTRACT        Nondestructive analysis of a porous, inhomogeneous, generally cylindrical object, such as a soot boule, comprised of n known components, where n is an integer, is achieved by scanning the boule with a beam comprised of photons, each having a distinct energy within one n-1 energy groups.  The intensity of the photons within each of the n-1 energy groups leaving the boule is detectedby a detector and is measured by a pulse height/scaler analyzer at each of a plurality of separate heights ti of the beam as measured from the center of the boule.  A computer determines each of n-1 attenuation coefficients µ1(r), µ2(r),...µn(r), representing the attenuation of the intensity of the photons in each of the n-1 energy groups, respectively, at each height ti of the beam in accordance with the output data furnished by the scaler/analyzer.  From the n-1 attenuation coefficients, the computer determines the density p(r) and the respective molecular mass fractions x1(r), x2(r)...xn(r) of the n molecular components of the boule at each height ti of the beam.

Abstract: OPTICAL FIBER CONNECTORS AND METHODS OF MAKING            Abstract In order to connect two optical fibers (26-26), each of two plugs (40-40) each having a passageway (41) in which is received an optical fiber are mounted in a connector body (42).  The plugs are destined to be received in a sleeve (75) of a coupler (60) such that their longitudinal axes are coaxial.  Alignment  of the passageways, at least radially of the longitudinal axes, is accomplished by locating for each plug the intersection of a radial line which extends through the centroid of an opening of the passageway with the periphery of the plug.  Each plug is mounted in its connector body such that the intersection is aligned radially with a pin extending from the connector body.  The connector bodies are inserted into opposite ends of the coupler sleeve to cause each pin of each connector body to be received in a slot in the coupler.  The slots are aligned so that when the connector bodies are inserted into the coupler, the plugs are caused to be inserted into the sleeve such that the centroids of the passageways, and of the optical fibers, are aligned, at least along a plane that originates at and extends radially from the longitudinal axes.

Abstract: ABSTRACT OF THE DISCLOSURE          In an optical recording system using a semiconductor diode laser and having both read and write capabilities, the laser power must be carefully controlled at appropriate different levels for reading and writing.  A continuous read beam is emitted by the laser while write pulses at a higher power level are generated.          The laser power control loop of the present disclosure maintains both the read and write output power levels of the laser within predetermined limits.  A light sensing diode is used to determine laser output power and operate the control circuit by adjusting the read and write current to the laser.  The sensing diode vol-tage is passed through a read/write switch which is controlled by write pulses, which also control the laser.  In read mode a DC signal is sent to a quad comparator circuit for read power control.          In write mode a pulsed signal is sent to a sample and hold circuit whose output goes through an amplifier to another quad comparator circuit for write power control.  The outputs of the comparators update the read and write power control circuits which determine the current levels to be provided to the laser diode during these operations.  The power control circuits are counters which step up or down after every power measurement, if necessary, and a D/A converter controlled by the counter which drives the current sources.  When the counters reach the end of the range limit this signals that the laser is close to a failing condition and at this time a warning signal is emitted.  Error status signals are emit-ted if the read or write power signals indicate the absence of, or an improper signal.

All types of textile fabrics, wool, made-up goods, tufted carpets, etc. may be treated by the process. Thus made up goods such as pullovers can be dyed by applying the dyebath mist while the goods are rotating in a closed drum; textile fabrics can be treated continuously by passing them through an impregnation chamber contg. the dyebath mist. The impregnated materials are then heat treated to fix the dye, washed and dried. The process gives even dyeing of the materials while using ver low bath ratios, thus, which causes less problems with effluent water disposal than known dyeing processes.
