Abstract: ABSTRACT         A method of controlling exposure in the production of photographic prints by scanning an original point-by-point and determining the neutral density of each point of the picture, the densities being processed to provide exposure data to control the exposure of sensitised paper to produce a print from the original.  To provide the optimum print quality as required by this method, the picture area of the original is divided up into tones, each of which as at least two picture points, the density values obtained by scanning the original are processed with a density value of a point in a reference picture to provide intermediate density values for each zone in accordance with processing instructions which vary from zone to zone, the intermediate values then serving to form an end density value to control the exposure of the print material.  When printing in colour the colour original is scanned to provide density values in each of the three primary colours at each point of a zone and the three colour density signals are then similarly processed to provide the exposure data for the colour print material.

Title: Low pressure gas burner
Inventor: BECKMANN MARTIN J
IPC: F23G7/08

Granted: 1978-10-03
Abstract: "LOW PRESSURE GAS BURNER"                 ABSTRACT OF THE DISCLOSURE              The burner comprises inner and outer tubular concentrically arranged conduits having their outlets positioned approximately in the same plane.  The inner conduit is connected to a high pressure gas source; the outer conduit is connected to a low pressure gas source.  The end face of the inner conduit forms a valve seat in which a Coanda-type valve body seats.          The valve body is axially displaceable away from the valve seat so as to co-operate therewith to form an annular passage.  A tubular shroud concentrically surrounds the conduit outlets and valve body in spaced relation therewith.  In operation, high pressure gas unseats the valve body and flows at high velocity through the annular passage.  This gas flow follows the surface of the valve body in the form of an attached jet and creates a low pressure zone adjacent said valve body surface, with the result that low pressure gas is sucked or drawn out of the outer conduit and simultaneously air is drafted into the annulus formed between the shroud and the valve body.  The three streams mix in the annulus to form a combustible mixture.  The burner is advantageous in that it provides improved suction and mixing, thereby using a relative-ly low amount of high pressure gas in its operation.

Abstract: ABSTRACT OF THE DISCLOSURE         Hydrocarbons are formed of coal and water.  The water is converted or dissociated separately into hydrogen and oxygen in a first chemical reactor by thermochemical and/or electrolytic processing.  The resulting hydrogen is then reacted with the coal in a second reactor to pro-duce the hydrocarbons.  Residual carbon from the second reactor is reacted in a third reactor with oxygen derived from the first reactor to produce carbon monoxide.  The carbon monoxide is reacted with residual hydrogen from the second reactor or hydrogen from the first reactor to produce additional hydrocarbons.  The energy for the endothermic and/or electrolytic processing in the reactors and for auxiliary equipment of the apparatus is supplied by a very high-temperature, gas-cooled, nuclear reactor by heat interchange with the cooling gas, helium.  The cooling gas operates through heat-exchange means which isolates the cooling gas from the processing apparatus.

Abstract: ABSTRACT         Earth boring apparatus is mounted above ground and directs an annulus of high powered laser energy downwardly for boring a cylindrical hole by fusing successive annular regions of the stratum to be penetrated at a power level that shatters and self-ejects successive cores from the hole.  A first fluid blast above the hole deflects the ejected core as it exits from the hole.  A second fluid blast above the hole ejects fluid to provide adequate fluid at the strata to be penetrated prior to actuation of the laser for promoting a thermal shock capable of shattering and ejecting the core.         Optical sensing separately detects the core shattering and the core ejection to control timed actuation of the system components.

Abstract: VARIABLE P-R INTERVAL PACEMAKER            ABSTRACT         A pacemaker has circuitry which allows the time between the detection of an atrial contraction and the provision of an electrical stimulus to cause a ventricular contraction to vary with the rate of the sensed atrial contractions.  The circuitry includes a differential amplifier having a reference voltage applied to one input and a capacitor coupled to the second input.  The capacitor is charged from the time the atrial contraction is sensed to the time the charge equals the reference vol-tage, at which time the electrical stimulus is provided and the capacitor is discharged between the time the elec-trical stimulus is provided and the next atrial contraction is sensed.  As the heart rate increases, the time between the atrial contractions decreases, and thus the capacitor discharges for a shorter time, or in other words, to a larger voltage and the time required for the capacitor to recharge to the reference voltage becomes less.

Abstract: TRIM POSITION INDICATOR FOR MARINE MOTORS                 Abstract of the Disclosure A marine jet drive unit includes a nozzle which is mounted in a gimbal ring for pivoting about a horizontal axis for trimming of the drive jet.  An electric motor drives a gear train including a rotating actuator shaft having an Acme nut actuator connected by a rigid linkage to the gimbal ring for trim positioning of the nozzle.  A potentiometer is mounted within the gear housing with an input shaft parallel to the actuator shaft.  The outer ends of both shafts are exposed in laterally spaced, aligned relation. A  large driven disc element is secured to the potentiometer shaft and has a radium slightly less than the spacing between the two shafts.  A pair of small, disc elements are mounted on the actuator shaft with a small flat spring establishing a spring force urging the small, disc elements into clamping engagement with the periphery of the large disc.  The gear and actuator shaft are driven through less then one complete revolution by the motor for the complete  angular trim orienta-tion of the nozzle. During the initial installation, auto-matic alignment of the shafts is produced by moving the nozzle to its limit positions. The potentiometer moves to an appropriate limit position during at least  one of the trim positions, with slippage between the large and small clamping disc elements permitting the nozzle to move to its limit position and thereby produce proper alignment at The maximum trim position.

Abstract: Abstract  of  the  Disclosure The present invention relates to a method of and a cryogenic installation for distributing gases.     From a storage tank at low pressure, successive portions of cryogenic liquid are withdrawn to an enclosure, which is isolated by closing a valve.          After this a further valve is opened, the effect of which is to cause the pressure in a receptacle to rise to the high distribution pressure and to allow the gas concerned to condense to a certain degree so that said enclosure is filled with liquid under pressure.  The liquid evaporates partially at the periphery and is thus transferred to a heater and from there to a buffer container.    The invention is applicable in particular to the distribution of oxygen, nitrogen and argon under pressure.

Abstract: Canadian Abstract The life of copper-containing catalysts in the low temperature shift reaction of carbon monoxide with steam is limited as a result of slow poisoning by halogen and/or sulphur compounds.  It has been found that the poisoning reaction and the shift reaction occur almost entirely on the surface of the catalyst pellets, and that the rate at which a catalyst charge loses activity can be decreased by having the catalyst in an inlet zone in a form more accessible to the reacting gas than that catalyst downstream thereof.  The inlet zone catalyst pieces can be smaller and/or formed with indentations or protrusions and/or more macroporous in order to provide better access.
