Abstract: ABSTRACT     A PROCESS FOR CONVERTING COAL AND/OR HEAVY PETROLEUM  FRACTIONS INTO HYDROGEN OR AMMONIA SYNTHESIS GAS.     Hydrogen or ammonia synthesis gas consisting substantially only of hydrogen and nitrogen is prepared from coal and/or heavy petroleum fractions by gasification with steam and an oxygen-containing gas, cooling the thus-formed crude gas by quenching and/or steam production, scrubbing the cooled gas to remove soot and other solid impurities, re-heating by heat exchange with exit gas from a subsequent conversion step, shift-converting the re-heated, soot-free crude gas to convert its CO by passing the gas through one ore more catalyst beds of one or more sulfur-resistant shift catalysts, removing acid gases (notably H2S and CO2) from the shift-converted gas and finally subjecting the gas to a catalytic methanation to convert remaining amount of carbon oxides to methane. If the process is used for preparing ammonia syngas, the gasification is conveniently carried out with oxygen-enriched air and steam.

Abstract: BAYONET JOINT BACKSET ADJUSTMENT FOR LATCH CONSTRUCTIONS          Abstract of the Disclosure:         A bolt is conventionally reciprocal in a stationary casing with each being formed of longitudinally telescoped parts and with the parts of each being bayonet joint connected.          Each bayonet joint connection is comprised of a projection of one part selectively movable in a pair of longitudinally spaced, transverse slots separated by a longitudinal slot in the other part, whereby each may be selectively long-itudinally adjusted the same determined amount for increasing or decreasing the backset distance between the forward extremities of the casing and the latch operator transverse axis  the same determined amount.  The transverse cross sections of certain slidably reciprocal mating parts of the bolt and casing are formed generally mutually rectangular so that rotational movements of one during the backset adjustment will positively require the same rotational movements of the other.  A spring-pressed friction member between the casing telescoped parts frictionally resists movement therebetween minimizing any danger of non-planned, accidental backset adjustment.

Abstract: ABSTRACT OF THE INVENTION       This invention relates to the preparation of aqueous dispersions of film-forming polymer particles wherein the dispersions comprise both pre-formed polymer and polymer formed in situ, and to the use of these dispersions in coating compositions which can be applied by cationic electrophoresis.        Previous dispersions of the general type hereinabove described can be cationically electrodeposited but do not give films of adequate integrity and adhesion.        The present invention overcomes these drawbacks by using a process wherein (a) pre-formed polymer or polymer plasciciser is dissolved in polymerisable monomer and the resulting solution stably dispersed in water in the presence of a surface active agent, and (b) the monomer is polymerised to give a particulate dispersion. Prior to polymerisation the dispersion must comply with specific pH requirements involving ensuring instability within the pH range 10-11 and the surface active agent must be cationic and have an H.L.B. value of at least 8.

Abstract: Abstract of the Disclosure An automatic flue gas heat recovery system for supplementing or replacing a conventional, separate hot water system.  In the example described, the heat recovery system is applied to a pizza restaurant where large quantities of heat energy are normally wasted up an oven chimney stack, and large quantities of hot water also are required for restaurant operations.  An electric motor driven pump circulates water in a closed loop between a storage tank and a heat exchanger tube located in the oven chimney stack.  A thermostat control automatically starts the pump when the open heats the chimney stack to an effective water heating temperature.  When temperature in the storage tank reaches a predetermined maximum, the thermostat control stops the pump, opens a drain valve, and dumps water quickly and completely from the heat exchanger tube.  Three different embodiments are shown and described illustrating systems with one or more storage tanks and one or more pumps.  In the plural storage tank embodiments, an-existing hot water heating tank may be converted for use to augment a main tank supplied with the present system.

Abstract: ABSTRACT OF THE DISCLOSURE      Control apparatus having n time division chan-nels, controls an m-stage data processing pipeline (n> m> l) for performing operations interleaved and overlapped in time relative to n circuit channels. This apparatus contains m serially coupled control modules associated with respective stages of the pipeline and a source of address signals linked to a first module in the series.  Each module includes a control memory, an address register for addressing the memory, an output register for latching addressed control words read out from the memory, and means coupled to the output register for controlling the associated stage of the data pipeline.  The address registers are serially coupled to form an address pipeline paralleling the data pipeline.  A read/write memory supplies addresses associated with the n channels to a first stage in the address pipeline on a time interleaved basis.  These addresses are shifted through the address pipeline in parallel with the movement of associated data through the data pipeline.  Simultaneously, new addresses associated with channels currently completing a round of service in the data pipelines, are written into the address memory.  Each new address is composed selectively from information in an address register, a control memory output register and the data pipeline.  In the preferred embodiment each circuit channel has plural sub-channels, or activity levels, to each of which a unique location is dedicated in the address memory. Readout access to such dedicated locations is varied dynamically, for each channel, as a function of control word information and external conditions relating to associated sub-channels.  Such variations effect transfers of control between activity levels.

Abstract: ABSTRACT              Apparatus for Use in Processing a Substance in a Fluidized Bed The apparatus comprises a process vessel (11) containing a process bed (16) of fluidized particles, having a submerged entrance port (19) at one end and a submerged exit port (24) at the other end.  Preferably the exit port (24) provides an exit path for particles from the process bed (16) to a second fluidized bed (41) of particles in a second vessel (40) and the entrance port (l9) provides an entrance path for particles to enter the process bed (16) from the second bed (41).  The bottom of the entrance port (19) is defined by a ramp (20) which slopes downwardly from a location (e.g. in the second bed (40)) outside the process vessel (11) to a sump area within the process vessel (11), the base of the sump area being defined by a first gas distributor (23).  A second gas distributor (28) extends horizontally at a higher level from a side of the sump area to the vicinity of the exit port (24) and preferably a step (29) defines the side of the sump area.  Vigorous fluidization of particles in the sump area removes particles from the lower end of the ramp (20) faster than they can accumulate thereby promoting a flow of particles from the entrance port (19) to the exit port (24).  A similar combination of a sloping ramp (25) and distributors (43,44) at two levels in the second vessel (40) promotes particle-circulation in one sense through both fluidized beds (16,41).  A relatively low density substance (e.g. coal) added (31) to the sump area of the process bed (16) is largely retained in the process bed (16) while denser particles (e.g. Ca0 and CaS04) circulate from the process bed (16) to the second bed (41) and return to the process bed (16).  The second bed (41) is preferably for oxidation and heating the denser bed particles.
