Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided herein for the ignition of a coal dust annular burner flame having an internal back flow region.  The ignition energy is supplied at least partially by a dust-ignition flame and  is introduced centrally into the internal back flow region of the coal dust annular burner flame.  The ignition burner flame is operated with a fuel dust which differs from the main fuel in at least one of the properties of granular size and consistency.  The dust air-dust weight ratio for the dust-ignition flame is smaller (0.5 to 1.0) than that of the main burner flame (1.5 to 2.0).  The dust ignition flame is operated at a smaller air number (.lambda. =0.8 to 1.1) than the main burner flame (.lambda. =1.1 to 1.3) thus providing the main burner with a core-air passage.  The com-bustion air is supplied to the ignition burner flame by means of that core-air passage.

Abstract: ABSTRACT     Compositions which are stable in the absence of oxygen are obtained by mixing the following substantially in the  absence of oxygen (A)  100 parts by weight of an ingredient selected from either (1) at least one mercapto-functional copolymer, said copolymer containing both silicon-free organic segments and organosiloxane segments or (2) a mixture of at least two different types of components selected from the following types (a) at least one copolymer as described in (A)(1) above, (b) at least one silicon-free mercapto-functional organic compound and (c) at least one mercapto-functional organosilane or organosiloxane; (B)  0 to 200 parts of at least one filler; and (C)  a catalytic amount, preferably from 0.1 to 6 parts, of a metal carbonyl catalyst selected from the group consisting of Fe(CO)5, Fe2(CO)9, Fe3(CO)12, dicyclopentadienyldiiron tetracarbonyl, butadieneiron tricarbonyl, cyclohexadiene-iron tricarbonyl, Ni(CO)4, dicyclopentadienyldinickel dicarbonyl, Mn2(CO)10, methylcyclopentadienylmanganese tricarbonyl and dicyclopentadienylcobalt dicarbonyl.     Such compositions polymerize or cure to form higher molecular weight product  upon exposure to oxygen at room temperature.  The higher molecular weight products formed are useful as coatings, impregnants for porous materials and elastomeric sealants.  Cured products possessing a combination of some of the advantages possessed by organosiloxanes and some of the advantages possessed by organic polymers are easily obtained by exposing these compositions to oxygen.

Abstract: ABSTRACT OF THE DISCLOSURE:         A heat-exchanger co-planar with parallel flat-sided pipes connected, at a distance inwardly of their ends, to manifolds for the supply and return flow of a fluid medium.  The flat pipes have very small internal clear widths and the ratio of the internal cross-sectional area to the outer circumferential length of each pipe is less than or equal to 2.5.  When the heat-exchanger serves as a heater body, the heating medium flows with correspondingly greater velocity through the flat-sided pipes because of the relatively small pipe cross-section.  From this, there results a smaller thermal inertia and a better heat transfer for the heat-exchanger.  The flat pipes are closed at their inwardly bent ends by means of a welding seam.  Outwardly pressed wall regions of the manifold surround bores therein and are connected by welding with corresponding wall regions of the flat pipe, the welding taking place from the inside of the manifold.  The manifold consists of at least two parts which are secured together into a rectangular-section manifold by means of welding seams running along the length of the manifold.

Abstract: ABSTRACT OF THE DISCLOSURE A process for gasifying coal and other carbon-aceous matter is disclosed which produces fuel gas con-taining low concentrations of polycyclic aromatic hydro-carbons.   In this process the polycyclic aromatic hydro-carbons released by the coal during devolatilization and formed during pyrolysis of volatile matter are decomposed thermally in the presence of hydrogen, at a sufficiently high partial  pressure  (obtained by increasing the total pressure  in  the  gasifier)  to prevent  polymerization of free  radicals  formed  during pyrolysis.   A  relationship between the  temperature,  the gas residence tine  in the gasification  reactor, the hydrogen partial pressure (i.e., total pressure in the gasifier), and the coal feed condi-tions are specified to achieve "clean" coal gasification

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus is provided herein for inhalation rewarming for the treatment of victims of hypothermia.  The apparatus includes a water reser-voir.  A steam chamber communicates with ambient air.  A heater means is associated with such water chamber, for the generation of steam into such steam chamber.  An opening is provided admitting air to the steam chamber, thereby to provide an air-steam mixture.  A first conductor is connected to the steam chamber for the conducting of the air-steam mixture from the steam chamber in a first direction.  A valve is provided in the first con-ductor for varying the inflow of the ambient air while simultaneously re-ciprocally varying the inflow of the air-steam mixture and providing a sub-stantially constant volume flow into the first conduit means.  The valve includes actuated operator means for initially introducing sufficient ambi-ent air into the air-steam mixture in the first conductor means to provide a continuous flow of the water-saturated air at the temperature of about 35°C- about 45°C.  A flexible conduit leads from the valve means for con-ducting the water-saturated air in the first direction.  Finally a breath-ing mask is connected to  the flexible conduit means downstream of the valve means.  The breathing mask includes one-way valves therein to permit the water-saturated air-to flow only in the first direction to the breathing mask, whereby the water-saturated air at the temperature of about 35°C-about 45°C is drawn into the breathing mask by the negative pressure pro-duced by human inhalation, and exhaled air produced by human inhalation is vented.  Thus, a simple, effective apparatus for inhalation rewarming has been provided which has special relevance to first-aid treatment of accidental hypothermia.

Granted: 1982-04-27
Abstract: ABSTRACT A vapor fraction containing hydrogen and at least one hydrocarbon selected from the group consisting of C1 to C4 hydrocarbons is separated from a hydrogen-rich refinery off-gas feed to give a liquid product fraction. The refinery off-gas is fed to and compressed in a com-pressor/expander having compressor means and expander means mounted and driven on a common shaft, and then cooled and partially condensed to form a two-phase fluid in a heat exchanger followed by separation of the vapor and liquid product phases of the fluid in a separator or a separator/fractionation column stabilizer unit. The separated vapor phase is transmitted to the compressor/ expander unit wherein the vapor is depressurized and partially condensed, thereby driving the compressor. The partially condensed depressurized vapor fraction from the expander and, optionally, the liquid phase product fraction from the separator are transmitted in separate streams to the heat exchanger for separate thermal contact with the compressed feed gas wherein the partially con-sensed depressurized vapor fraction is fully vaporized and the feed gases are cooled. The fully vaporized fraction and the liquid product fraction are recovered in separate streams.
